Research on partitioning Bitcoind nodes: "Eclipse Attacks on Bitcoin’s Peer-to-Peer Network" | Ethan Heilman | Mar 23 2015

Ethan Heilman on Mar 23 2015:
Hi All,
There has been much discussion lately on the dev list about
misbehaving peers and attacks on the P2P network. We'd like to share
our research on partitioning Bitcoind nodes from the rest of the
network.
Eclipse Attacks on Bitcoin’s Peer-to-Peer Network
Abstract: We present eclipse attacks on bitcoin's peer-to-peer
network. Our attack allows an adversary controlling a sufficient
number of IP addresses to monopolize all connections to and from a
victim bitcoin node. The attacker can then exploit the victim for
attacks on bitcoin's mining and consensus system, including
N-confirmation double spending, selfish mining, and adversarial forks
in the blockchain. We take a detailed look at bitcoin’s peer-to-peer
network, and quantify the resources involved in our attack via
probabilistic analysis, Monte Carlo simulations, measurements and
experiments with live bitcoin nodes. Finally, we present
countermeasures, inspired by botnet architectures, that are designed
to raise the bar for eclipse attacks while preserving the openness and
decentralization of bitcoin’s current network architecture.
Full paper available here:

Thanks,
Ethan

Hans Moog: War and Peace

Hans Moog: War and Peace...
Basically, IOTA is truly going to rule them all and have the best, safest, and fastest network after Shimmer, Mana, and eventually sharding and or clustering is implemented.
If you have any doubts or any theories of weaknesses against the Coordicide solution, you just have to put in about an hour of reading.
If you have any assumptions that the Coordicide solution is "just" like Avalanche, again, put the work in and read.
If you still have any doubts or theories after reading this, then please, we the IOTA community begs you to prove when it gets put on the public testnet. FYI, this is not a "simulation testnet", this is a real live public net, just for testing purposes, but acts just like the mainnet. So hook up a node and prove your theory or your doubts. If you can, you will help improve the tech and even make a name for yourself, and if you can't, then there is no more arguments.
--- The attached is a .txt file that includes Hans Moog's discussions over the past few days. He specifically discusses: - Why shimmer holds up against splitting attacks - How Coordicide solution protects itself against eclipse attacks - How Mana works and how Mana is not like DPos - How Mana can not be monopolized by a few and attack the network - How Mana supports the "value" of the token - How Auto-Peering and secrete nodes protect against eclipse attacks - How double spending is pretty much not possible - How there is no difference between TPS & CTPS but rather "liked" (confirmed) and finality. Ie: a coffee shop looks for a confirmed transaction (1 ms or 1 second) and a person selling their house looks for finality ( 5 or 10 minutes)... (FYI that is HUGE) - How once a transaction or a piece of the Tangle is considered final, no amount of PoW or Mana in the world can "reorg" or change the past. - How after finality is confirmed, through hashes, the Tangle can be querried 10 years ago and checked for legitimacy; and that 10 years of such data can fit on a thumb drive (still confused on this). - Also, how Coordicide is as much as to Avalanche as Ethereum is to Bitcoin, or even as much as AVA is to IOTA.
Enjoy!

Failing shortcuts in an attempt to accomplish Quantum Resistance
Content:
Hashing public keys
“Instant” transactions
FIFO
Standardized fees
Multicast
Timestamped transactions
Change my mind: If a project doesn't use a Quantum Resistant signature scheme, it is not 100% Quantum Resistant.
Here are some of the claims regarding Quantum Resistance without the use of a quantum resistant signature scheme that I have come across so far. For every claim, I give arguments to substantiate why these claims are incorrect.
“We only have public keys in hashed form published. Even quantum computers can't reverse the Hash, so no one can use those public keys to derive the private key. That's why we are quantum resistant.” This is incorrect.
This example has been explained in the previous article. To summarize: Hashed public keys can be used as an address for deposits. Deposits do not need signature authentication. Alternatively, withdrawals do need signature authentication. To authenticate a signature, the public key will always need to be made public in full, original form. As a necessary requirement, the full public key would be needed to spend coins. Therefore the public key will be included in the transaction.
The most famous blockchain to use hashed public keys is Bitcoin. Transactions can be hijacked during the period a user sends a transaction from his or her device to the blockchain and the moment a transaction is confirmed. For example: during Bitcoins 10 minute blockchain, the full public keys can be obtained to find private keys and forge transactions. Page 8, point 3 Hashing public keys does have advantages: they are smaller than the original public keys. So it does save space on the blockchain. It doesn't give you Quantum Resistance however. That is a misconception.
“Besides having only hashed public keys on the blockchain, we also have instant transactions. So there is no time to hijack a transaction and to obtain the public key fast enough to forge a transaction. That's why we are quantum resistant.” This is incorrect and impossible.
There is no such thing as instant transactions. A zero second blocktime for example is a claim that can’t be made. Period. Furthermore, transactions are collected in pools before they are added to a block that is going to be processed. The time it takes for miners to add them to a new block before processing that block depends on the amount of transactions a blockchain needs to process at a certain moment. When a blockchain operates within its maximum capacity (the maximum amount of transactions that a blockchain can process per second), the adding of transactions from the pool will go quite swiftly, but still not instantaneously.
However, when there is high transaction density, transactions can be stuck in the pool for a while. During this period the transactions are published and the full public keys can be obtained. Just as with the previous hijacking example, a transaction can be forged in that period of time. It can be done when the blockchain functions normally, and whenever the maximum capacity is exceeded, the window of opportunity grows for hackers.
Besides the risk that rush hours would bring by extending the time to work with the public key and forge transactions, there are network based attacks that could serve the same purpose: slow the confirmation time and create a bigger window to forge transactions. These types are attacks where the attacker targets the network instead of the sender of the transaction: Performing a DDoS attack or BGP routing attack or NSA Quantum Insert attack on a peer-to-peer network would be hard. But when provided with an opportunity to earn billions, hackers would find a way.
For example: https://bitcoinmagazine.com/articles/researchers-explore-eclipse-attacks-ethereum-blockchain/
For BTC: https://eprint.iacr.org/2015/263.pdf
An eclipse attack is a network-level attack on a blockchain, where an attacker essentially takes control of the peer-to-peer network, obscuring a node’s view of the blockchain.
That is exactly the recipe for what you would need to create extra time to find public keys and derive private keys from them. Then you could sign transactions of your own and confirm them before the originals do.
This specific example seems to be fixed now, but it most definitely shows there is a risk of other variations to be created. Keep in mind, before this variation of attack was known, the common opinion was that it was impossible. With little incentive to create such an attack, it might take a while until another one is developed. But when the possession of full public keys equals the possibility to forge transactions, all of a sudden billions are at stake.
“Besides only using hashed public keys as addresses, we use the First In First Out (FIFO) mechanism. This solves the forged transaction issue, as they will not be confirmed before the original transactions. That's why we are quantum resistant.” This is incorrect.
There is another period where the public key is openly available: the moment where a transaction is sent from the users device to the nodes on the blockchain network. The sent transaction can be delayed or totally blocked from arriving to the blockchain network. While this happens the attacker can obtain the public key. This is a man-in-the-middle (MITM) attack. A MITM is an attack where the attacker secretly relays and possibly alters the communication between two parties who believe they are directly communicating with each other. No transaction is 100% safe from a MITM attack. This type of attack isn’t commonly known amongst average usergroups due to the fact communication is done either encrypted or by the use of private- public key cryptography. Therefore, at this point of time MITM attacks are not an issue, because the information in transactions is useless for hackers. To emphasize the point made: a MITM attack can be done at this point of time to your transactions. But the information obtained by a hacker is useless because he can not break the cryptography. The encryption and private- public key cryptography is safe at this point of time. ECDSA and RSA can not be broken yet. But in the era of quantum computers the problem is clear: an attacker can obtain the public key and create enough time to forge a transaction which will be sent to the blockchain and arrive there first without the network having any way of knowing the transaction is forged. By doing this before the transaction reaches the blockchain, FIFO will be useless. The original transaction will be delayed or blocked from reaching the blockchain. The forged transaction will be admitted to the network first. And First In First Out will actually help the forged transaction to be confirmed before the original.
“Besides having only hashed public keys, we use small standardized fees. Forged transactions will not be able to use higher fees to get prioritized and confirmed before the original transactions, thus when the forged transaction will try to confirm the address is already empty. This is why we are quantum resistant.” This is incorrect.
The same arguments apply as with the FIFO system. The attack can be done before the original transaction reaches the network. Thus the forged transaction will still be handled first no matter the fee hight.
“Besides the above, we use multicast so all nodes receive the transaction at the same time. That's why we are quantum resistant.” This is incorrect.
Multicast is useless against a MITM attack when the attacker is close enough to the source.
“Besides the above, we number all our transactions and authenticate nodes so the user always knows who he's talking to. That's why we are quantum resistant.” This is incorrect.
Besides the fact that you’re working towards a centralized system if only verified people can become nodes. And besides the fact that also verified nodes can go bad and work with hackers. (Which would be useless if quantum resistant signature schemes would be implemented because a node or a hacker would have no use for quantum resistant public keys and signatures.) There are various ways of impersonating either side of a communication channel. IP-spoofing, ARP-spoofing, DSN-spoofing etc. All a hacker needs is time and position. Time can be created in several ways as explained above. All the information in the transaction an original user sends is valid. When a transaction is hijacked and the communication between the user and the rest of the network is blocked, a hacker can copy that information to his own transaction while using a forged signature. The only real effective defense against MITM attacks can be done on router or server-side by a strong encryption between the client and the server (Which in this case would be quantum resistant encryption, but then again you could just as well use a quantum resistant signature scheme.), or you use server authentication but then you would need that to be quantum resistant too. There is no serious protection against MITM attacks when the encryption of the data and the authentication of a server can be broken by quantum computers.
Only quantum resistant signature schemes will secure blockchain to quantum hacks. Every blockchain will need their users to communicate their public key to the blockchain to authenticate signatures and make transactions. There will always be ways to obtain those keys while being communicated and to stretch the period where these keys can be used to forge transactions. Once you have, you can move funds to your own address, a bitcoin mixer, Monero, or some other privacy coin.
Conclusion
There is only one way to currently achieve Quantum Resistance: by making sure the public key can be made public without any risks, as is done now in the pre-quantum period and as Satoshi has designed blockchain. Thus by the use of quantum resistant signature schemes. The rest is all a patchwork of risk mitigation and delaying strategies; they make it slightly harder to obtain a public key and forge a transaction but not impossible.
Addition
And then there is quite often this strategy of postponing quantum resistant signature schemes
“Instead of ECDSA with 256 bit keys we will just use 384 bit keys. And after that 521 bit keys, and then RSA 4096 keys, so we will ride it out for a while. No worries we don’t need to think about quantum resistant signature schemes for a long time.” This is highly inefficient, and creates more problems than it solves.
Besides the fact that this doesn’t make a project quantum resistant, it is nothing but postponing the switch to quantum resistant signatures, it is not a solution. Going from 256 bit keys to 384 bit keys would mean a quantum computer with ~ 3484 qubits instead of ~ 2330 qubits could break the signature scheme. That is not even double and postpones the problem either half a year or one year, depending which estimate you take. (Doubling of qubits every year, or every two years). It does however have the same problems as a real solution and is just as much work. (Changing the code, upgrading the blockchain, finding consensus amongst the nodes, upgrading all supporting systems, hoping the exchanges all go along with the new upgrade and migrate their coins, heaving all users migrate their coins.) And then quite soon after that, they'll have to go at it again. What they will do next? Go for 512 bit curves? Same issues. It's just patchworks and just as much hassle, but then over and over again for every “upgrade” from 384 to 521 etc.
And every upgrade the signatures get bigger, and closer to the quantum resistant signature sizes and thus the advantage you have over blockchains with quantum resistant signature schemes gets smaller. While the quantum resistant blockchains are just steady going and their users aren’t bothered with all the hassle. At the same time the users of the blockchain that is constantly upgrading to a bigger key size, keep on needing to migrate their coins to the new and upgraded addresses to stay safe.

Key notes from the White Paper

http://docs.neo.org/en-us/
 
Digital Assets
Digital assets are programmable assets that exist in the form of electronic data. With blockchain technology, the digitization of assets can be decentralized, trustful, traceable, highly transparent, and free of intermediaries.
 
Digital Identity
Digital identity refers to the identity information of individuals, organizations, and other entities that exist in electronic form.
Our verification of identity when issuing or using digital identities includes the use of facial features, fingerprint, voice, SMS and other multi-factor authentication methods.
 
Smart Contracts
The NeoContract smart contract system is the biggest feature of the seamless integration of the existing developer ecosystem. Developers do not need to learn a new programming language but use C#, Java and other mainstream programming languages in their familiar IDE environments (Visual Studio, Eclipse, etc.) for smart contract development, debugging and compilation. NEO's Universal Lightweight Virtual Machine, NeoVM, has the advantages of high certainty, high concurrency, and high scalability. The NeoContract smart contract system will allow millions of developers around the world to quickly carry out the development of smart contracts.
 
Economic Model
NEO has two native tokens, NEOand NeoGas NEO represents the right to manage the network. Management rights include voting for bookkeeping, NEO network parameter changes, and so on. The minimum unit of NEO is 1 and tokens cannot be subdivided. GAS is the fuel token for the realization of NEO network resource control. The NEO network charges for the operation and storage of tokens and smart contracts, thereby creating economic incentives for bookkeepers and preventing the abuse of resources. The minimum unit of GAS is 0.00000001.
 
Distribution Mechanism
NEO's 100 million tokens are divided into two portions. The first portion is 50 million tokens distributed proportionally to supporters of NEO during the crowdfunding. This portion has been distributed.
The second portion is 50 million NEO managed by the NEO Council to support NEO's long-term development, operation and maintenance and ecosystem. The NEO in this portion has a lockout period of 1 year and is unlocked only after October 16, 2017. This portion will NOT enter the exchanges and is only for long-term support of NEO projects. The plans for it are as below:
▪ 10 million tokens (10% total) will be used to motivate NEO developers and members of the NEO Council
▪ 10 million tokens (10% total) will be used to motivate developers in the NEO ecosystem
▪ 15 million tokens (15% total) will be used to cross-invest in other block-chain projects, which are owned by the NEO Council and are used only for NEO projects
▪ 15 million (15% total) will be retained as contingency
▪ The annual use of NEO in principle shall NOT exceed 15 million tokens
 
GAS distribution
GAS is generated with each new block. The initial total amount of GAS is zero. With the increasing rate of new block generation, the total limit of 100 million GAS will be achieved in about 22 years. The interval between each block is about 15-20 seconds, and 2 million blocks are generated in about one year. According to this release curve, 16% of the GAS will be created in the first year, 52% of the GAS will be created in the first four years, and 80% of the GAS will be created in the first 12 years. GAS will be distributed proportionally in accordance with the NEO holding ratio, recorded in the corresponding addresses. NEO holders can initiate a claim transaction at any time and claim these GAS tokens at their holding addresses.
 
Consensus mechanism: dBFT
The dBFT is called the Delegated Byzantine Fault Tolerant, a Byzantine fault-tolerant consensus mechanism that enables large-scale participation in consensus through proxy voting. The holder of the NEO token can, by voting, pick the bookkeeper it supports. The selected group of bookkeepers, through BFT algorithm, reach a consensus and generate new blocks. Voting in the NEO network continues in real time, rather than in accordance with a fixed term.
 
Cross-chain assets exchange agreement
NeoX has been extended on existing double-stranded atomic assets exchange protocols to allow multiple participants to exchange assets across different chains and to ensure that all steps in the entire transaction process succeed or fail together. In order to achieve this function, we need to use NeoContract function to create a contract account for each participant. If other blockchains are not compatible with NeoContract, they can be compatible with NeoX as long as they can provide simple smart contract functionality.
 
Cross-chain distributed transaction protocol
Cross-chain distributed transactions mean that multiple steps of a transaction are scattered across different blockchains and that the consistency of the entire transaction is ensured. This is an extension of cross-chain assets exchange, extending the behavior of assets exchange into arbitrary behavior. In layman's terms, NeoX makes it possible for cross-chain smart contracts where a smart contract can perform different parts on multiple chains, either succeeding or reverting as a whole. This gives excellent possibilities for cross-chain collaborations and we are exploring cross-chain smart contract application scenarios.
 
Distributed Storage Protocol: NeoFS
NeoFS is a distributed storage protocol that utilizes Distributed Hash Table technology. NeoFS indexes the data through file content (Hash) rather than file path (URI). Large files will be divided into fixed-size data blocks that are distributed and stored in many different nodes
 
Anti-quantum cryptography mechanism: NeoQS
The emergence of quantum computers poses a major challenge to RSA and ECC-based cryptographic mechanisms. Quantum computers can solve the large number of decomposition problems (which RSA relies on) and the elliptic curve discrete logarithm (which ECC relies on) in a very short time. NeoQS (Quantum Safe) is a lattice-based cryptographic mechanism.
 

Reasons for choosing dBFT over PoW and PoS

 
With the phenomenal success of Bitcoin and its increasing mainstream adoption, the project’s unbounded appetite for energy grew accordingly. Today, the average Bitcoin transaction costs as much energy as powering 9.3 average American homes for 1 day.
https://digiconomist.net/bitcoin-energy-consumption#assumptions
This mind boggling amount of energy is not, as it is commonly believed, being wasted. It is put to good use: securing the Bitcoin network and rendering attacks on it infeasible. However, the cost of this security mechanism and its implications for an increasingly warming and resource hungry planet led almost the entire crypto industry to the understanding that an alternative has to be found, at least if we’re interested in seeing blockchain technology gaining overwhelming mainstream adoption.
The most popular alternative to PoW, used by most alternative cryptocurrency systems, is called Proof-of-Stake, or PoS. PoS is highly promising in the sense that it doesn’t require blockchain nodes to perform arduous, and otherwise useless, cryptographic tasks in order to render potential attacks costly and infeasible. Hence, this algorithm cuts the power requirements of PoS blockchains down to sane and manageable amounts, allowing them to be more scalable without guzzling up the planet's energy reserves.
As the name suggests, instead of requiring proof of cryptographic work, PoS requires blockchain nodes to proof stake in the currency itself. This means that in order for a blockchain node to be eligible for a verification reward, the node has to hold a certain amount of currency in the wallet associated with it. This way, in order to execute an attack, a malevolent node would have to acquire the majority of the existing coin supply, rendering attacks not only costly but also meaningless, since the attackers would primarily harm themselves.
PoS, as well as PoW, simply cause the blockchain to fork into two alternative versions if for some reason consensus breaks. In fact, most blockchains fork most of the time, only to converge back to a single source of truth a short while afterwards.
By many crypto enthusiasts, this obvious bug is very often regarded as a feature, allowing several versions of the truth to survive and compete for public adoption until a resolution is generated. This sounds nice in theory, but if we want to see blockchain technology seriously disrupt and/or augment the financial sector, this ever lurking possibility of the blockchain splitting into two alternative versions cannot be tolerated.
Furthermore, even the fastest PoS blockchains out there can accomodate a few hundred transactions per second, compare that to Visa’s 56,000 tx/s and the need for an alternative becomes clear as day.
A blockchain securing global stock markets does not have the privilege to fork into two alternative versions and just sit and wait it out until the market (or what’s left of it) declares a winner. What belongs to whom should be engraved in an immutable record, functioning as a single source of truth with no glitches permitted.
After investigating and studying the crypto industry and blockchain technologies for several years, we came to the conclusion that the delegated Byzantine Fault Tolerance alternative (or dBFT) is best suited for such a system. It provides swift transaction verification times, de-incentivises most attack vectors and upholds a single blockchain version with no risk of forks or alternative blockchain records emerging - regardless of how much computing power, or coins an attacker possesses.
The term Byzantine Fault Tolerance (BFT) derives its name from the Byzantine Generals problem in Game Theory and Computer Science, describing the problematic nature of achieving consensus in a distributed system with suboptimal communication between agents which do not necessarily trust each other.
The BFT algorithm arranges the relationship between blockchain nodes in such a way that the network becomes as good as resilient to the Byzantine Generals problem, and allows the system to remain consensus even if some nodes bare malicious intentions or simply malfunction.
To achieve this, Antshare’s version of the delegated BFT (or dBFT) algorithm acknowledges two kinds of players in the blockchain space: professional node operators, called bookkeeping nodes, who run nodes as a source of income, and users who are interested in accessing blockchain advantages. Theoretically, this differentiation does not exist in PoW and most PoS environments, practically, however, most Bitcoin users do not operate miners, which are mostly located in specialized venues run by professionals. At Antshares we understand the importance of this naturally occurring division of labor and use it to provide better security for our blockchain platform.
Accordingly, block verification is achieved through a consensus game held between specialized bookkeeping nodes, which are appointed by ordinary nodes through a form of delegated voting process. In every verification round one of the bookkeeping nodes is pseudo-randomly appointed to broadcast its version of the blockchain to the rest of the network. If ⅔ of the remaining nodes agree with this version, consensus is secured and the blockchain marches on. If less than ⅔ of the network agrees, a different node is appointed to broadcast its version of the truth to the rest of the system, and so forth until consensus is established.
In this way, successful system attacks are almost impossible to execute unless the overwhelming majority of the network is interested in committing financial suicide. Additionally, the system is fork proof, and at every given moment only one version of the truth exists. Without complicated cryptographic puzzles to solve, nodes operate much faster and are able to compete with centralized transaction methods.

OnChain

 
It is important to note the technical difference between Onchain and NEO. Onchain is a private VC-backed company with over 40 employees. NEO is a public platform with different community-led groups contributing to this public project. There exists NEO council comprised of the original NEO creators, employees from Onchain, full time NEO council members and there is also the first Western based group called City of Zion.
Onchain, a Shanghai-based blockchain R&D company, first started developing Antshares in February of 2014 which will eventually become the foundation of DNA. Onchain was founded by CEO Da HongFei and CTO Erik Zhang in response to the attention from private companies garnered by the development of Antshares, China’s first public blockchain. In contrast to the weeks-old start-ups launching ICOs that is happening currently in the blockchain world, it took them 22 long months of R&D to even begin providing services to their first customers. Finally, in April 2016, the first whitepaper on consensus protocol from China was born — the dBFT (delegated Byzantine Fault Tolerance) protocol.
2016 was a busy year for Onchain and they really picked up the pace that year. Other than continuing the development of Antshares, brushing shoulders with Fortune 500 companies, Onchain became the first Chinese blockchain company to join Hyperledger — an open source blockchain project started by the Linux Foundation specifically focusing on the development of private and consortium chains for businesses.
In June of 2016, during the first of many future partnerships with Microsoft China, Onchain founded Legal Chain specifically targeting the inadequacies of the digital applications within the legal system. In 2005, (Digital Signature Act) was passed into national law which permitted an effective digital signatures to gain the same legal rights as a real signature.
In company with Microsoft China, they are also aiming to integrate the technology with Microsoft’s face and voice recognition API function to kick start this digital revolution within the legal system. At the same time, a partnership was formed with FaDaDa, a third-party platform for electronic contracts that has processed over 27 million contracts to date, to provide secure evidence storage with DNA. If that’s not enough, they were also voted as KPMG’s top 50 Fintech Company in China and established a relationship with the Japanese Ministry of Economy, Trade and Industry which led to the recent tour to Japan. Finally, at the end of 2016 they announced a partnership with Alibaba to provide attested email service for Ali Cloud with Legal Chain where it provides a proof-of-existence for a blockchain-powered email evidence repository for enterprise-level use.
Fosun Group, China’s largest private conglomerate, have recently invested into Onchain in order to apply DNA across all of its businesses. Currently, Fosun International has a market cap of 102.98 billion dollars on the Hong Kong Stock Exchange and that is only its international branch.
The role of Onchain so far is reminiscent of Ethereum’s EEA in addition to a stronger emphasis of governmental cooperation. Onchain has identified the shortcomings of present laser focus of hype on public platforms such as NEO and Ethereum and addressing that with DNA. DNA envisions a future where a network of assorted, specifically designed blockchains serving private enterprises, consortiums, government and the public communicating with each other forming an interconnected blockchain network.
This is the goal of DNA — infiltrating every little inefficient niche that had no better alternatives before the invention of blockchain. What is especially critical to remember during this explosive time of hype driven partly by the obscene degree of greed is that not every little niche that blockchain can fill will be holding its own little ICO. Some of those efficiencies gained will simply be consumed by companies privately or by public systems such as the legal system.

Networks proves itself with the first ICO

 
ICOs, on other platforms such as Ethereum, often resulted in a sluggish network and transaction delays. While NEO’s dBFT consensus algorithm is designed to achieve consensus with higher efficency and greater network throughputt, no amount of theoretical calculations can simulate the reality of real-life conditions.
 

Key Observations

 
Smart Contract Invocations:
A total of 13,966 smart contracts invocations were executed on the NEO network over this time period, of which, nearly all called the RPX smart contract method mintTokens. A total of 543,348,500 RPX tokens were successfully minted and transferred to user accounts, totalling 10,097 smart contract executions.
 
Refunded Invocations:
A total of 4182 refund events were triggered by the smart contract method mintTokens. (Note: RPX has stated that these refunds will be processed within the next two weeks.)
 
Crowdsale Statistics:
A successful mintTokens execution used around 1043 VM operations, while an execution that resulted in a refund used 809 VM operations. Within the hour and six minutes that the token sale was active, a total of 12,296,409 VM operations were executed. A total of 9,575 unique addresses participated in the RPX ICO. Half of these, approximately 4,800 unique addresses, participated through CoZ’s Neon wallet. The top 3 blocks with the most transactions were block 1445025 (3,242 transactions), block 1444902 (2,951 transactions), and block 1444903 (1609 transactions).
 
Conclusion on Network Performance
At the moment, the consensus nodes for the NEO network are operated by the NEO Council in China. By Q1 2018, NEO Council aims to control less than two-thirds of the consensus nodes.
We are pleased to note that the NEO network continuted to operate efficiently with minimal network impact, even under extreme network events. Block generation time initially slowed down to 3 minutes to process the largest block, but quickly recovered to approximately 25 seconds. Throughout the entire RPX ICO, consensus nodes were able to achieve consensus and propagate new block transactions to the rest of the network. In closing, while we consider this performance to be excellent, NEO Council and City of Zion areworking closely together on upgrades, that will increase the throughputs of the NEO network.

Upcoming Roadmap

 
Decentralization of consensus nodes
▪ P2P Network optimization – Network optimizations to ensure fast block generation after decentralization.
▪ Voting Algorithm Optimization – Adjustments in voting algorithm to prevent identified attack vectors.
▪ Candidate List Website – Published list of candidates so that voters know who they are voting for.
▪ NEO Council Consensus Node < 2/3 – NEO Council shall operate less than two thirds of consensus nodes by the end of quarter 1, 2018.
 
Our original plan was to start decentralize in Q1 2018. We are however growing faster than expected and cannot accept the risk with being as centralized as we currently are. The conclusion is that we re-prioritize and start the process of decentralizing today. We believe that NEO community groups and exchanges will be suitable to run consensus nodes; community groups already know the technology, and exchanges are already running full nodes with high uptime and monitoring. We welcome interested parties to reach out to us on [email protected]. A NEP to encourage voting will be presented in the coming weeks.
https://neo.org/blog/Details/3016
 
Universal Data Format for Wallet/Node Prog.
▪ NEP2 – Private Key Encryption/Decryption (2017Q4) - Method for encrypting and encoding a passphrase-protected private key.
▪ NEP3 – Universal Data Format (2017Q4) – Standard data format to allow easier wallet and node programming.
https://neo.org/en-us/blog/details/65
 
Promotion/Ecosystem
▪ Globally Legal Token-raising Framework (2017Q4) – Following government interest to regulate ICO’s, NEO will complete a framework to raise tokens legally in all major markets by the end of 2017.
▪ NEO DevCon 1 (2017Q4) – First NEO Development Conference! More details at later date.
▪ CoZ Funding (2017Q4) – Continuous funding plan for CoZ covering next 5 years.
▪ Seed Projects (2017Q4) – First seed projects to be cross-invested with the dedicated NEO pool.

ICO Firm

 
Projectico
A service that helps others launch a token sale if it is right for their cause and will be using NEO in most instances going forward. We have created a foundation that is bringing compliance and trust to the marketplace for ICOs and allowing international people to still participate.

Key notes from the White Paper

http://docs.neo.org/en-us/
 
Digital Assets
Digital assets are programmable assets that exist in the form of electronic data. With blockchain technology, the digitization of assets can be decentralized, trustful, traceable, highly transparent, and free of intermediaries.
 
Digital Identity
Digital identity refers to the identity information of individuals, organizations, and other entities that exist in electronic form.
Our verification of identity when issuing or using digital identities includes the use of facial features, fingerprint, voice, SMS and other multi-factor authentication methods.
 
Smart Contracts
The NeoContract smart contract system is the biggest feature of the seamless integration of the existing developer ecosystem. Developers do not need to learn a new programming language but use C#, Java and other mainstream programming languages in their familiar IDE environments (Visual Studio, Eclipse, etc.) for smart contract development, debugging and compilation. NEO's Universal Lightweight Virtual Machine, NeoVM, has the advantages of high certainty, high concurrency, and high scalability. The NeoContract smart contract system will allow millions of developers around the world to quickly carry out the development of smart contracts.
 
Economic Model
NEO has two native tokens, NEOand NeoGas NEO represents the right to manage the network. Management rights include voting for bookkeeping, NEO network parameter changes, and so on. The minimum unit of NEO is 1 and tokens cannot be subdivided. GAS is the fuel token for the realization of NEO network resource control. The NEO network charges for the operation and storage of tokens and smart contracts, thereby creating economic incentives for bookkeepers and preventing the abuse of resources. The minimum unit of GAS is 0.00000001.
 
Distribution Mechanism
NEO's 100 million tokens are divided into two portions. The first portion is 50 million tokens distributed proportionally to supporters of NEO during the crowdfunding. This portion has been distributed.
The second portion is 50 million NEO managed by the NEO Council to support NEO's long-term development, operation and maintenance and ecosystem. The NEO in this portion has a lockout period of 1 year and is unlocked only after October 16, 2017. This portion will NOT enter the exchanges and is only for long-term support of NEO projects. The plans for it are as below:
▪ 10 million tokens (10% total) will be used to motivate NEO developers and members of the NEO Council
▪ 10 million tokens (10% total) will be used to motivate developers in the NEO ecosystem
▪ 15 million tokens (15% total) will be used to cross-invest in other block-chain projects, which are owned by the NEO Council and are used only for NEO projects
▪ 15 million (15% total) will be retained as contingency
▪ The annual use of NEO in principle shall NOT exceed 15 million tokens
 
GAS distribution
GAS is generated with each new block. The initial total amount of GAS is zero. With the increasing rate of new block generation, the total limit of 100 million GAS will be achieved in about 22 years. The interval between each block is about 15-20 seconds, and 2 million blocks are generated in about one year. According to this release curve, 16% of the GAS will be created in the first year, 52% of the GAS will be created in the first four years, and 80% of the GAS will be created in the first 12 years. GAS will be distributed proportionally in accordance with the NEO holding ratio, recorded in the corresponding addresses. NEO holders can initiate a claim transaction at any time and claim these GAS tokens at their holding addresses.
 
Consensus mechanism: dBFT
The dBFT is called the Delegated Byzantine Fault Tolerant, a Byzantine fault-tolerant consensus mechanism that enables large-scale participation in consensus through proxy voting. The holder of the NEO token can, by voting, pick the bookkeeper it supports. The selected group of bookkeepers, through BFT algorithm, reach a consensus and generate new blocks. Voting in the NEO network continues in real time, rather than in accordance with a fixed term.
 
Cross-chain assets exchange agreement
NeoX has been extended on existing double-stranded atomic assets exchange protocols to allow multiple participants to exchange assets across different chains and to ensure that all steps in the entire transaction process succeed or fail together. In order to achieve this function, we need to use NeoContract function to create a contract account for each participant. If other blockchains are not compatible with NeoContract, they can be compatible with NeoX as long as they can provide simple smart contract functionality.
 
Cross-chain distributed transaction protocol
Cross-chain distributed transactions mean that multiple steps of a transaction are scattered across different blockchains and that the consistency of the entire transaction is ensured. This is an extension of cross-chain assets exchange, extending the behavior of assets exchange into arbitrary behavior. In layman's terms, NeoX makes it possible for cross-chain smart contracts where a smart contract can perform different parts on multiple chains, either succeeding or reverting as a whole. This gives excellent possibilities for cross-chain collaborations and we are exploring cross-chain smart contract application scenarios.
 
Distributed Storage Protocol: NeoFS
NeoFS is a distributed storage protocol that utilizes Distributed Hash Table technology. NeoFS indexes the data through file content (Hash) rather than file path (URI). Large files will be divided into fixed-size data blocks that are distributed and stored in many different nodes
 
Anti-quantum cryptography mechanism: NeoQS
The emergence of quantum computers poses a major challenge to RSA and ECC-based cryptographic mechanisms. Quantum computers can solve the large number of decomposition problems (which RSA relies on) and the elliptic curve discrete logarithm (which ECC relies on) in a very short time. NeoQS (Quantum Safe) is a lattice-based cryptographic mechanism.
 

Reasons for choosing dBFT over PoW and PoS

 
With the phenomenal success of Bitcoin and its increasing mainstream adoption, the project’s unbounded appetite for energy grew accordingly. Today, the average Bitcoin transaction costs as much energy as powering 9.3 average American homes for 1 day.
https://digiconomist.net/bitcoin-energy-consumption#assumptions
This mind boggling amount of energy is not, as it is commonly believed, being wasted. It is put to good use: securing the Bitcoin network and rendering attacks on it infeasible. However, the cost of this security mechanism and its implications for an increasingly warming and resource hungry planet led almost the entire crypto industry to the understanding that an alternative has to be found, at least if we’re interested in seeing blockchain technology gaining overwhelming mainstream adoption.
The most popular alternative to PoW, used by most alternative cryptocurrency systems, is called Proof-of-Stake, or PoS. PoS is highly promising in the sense that it doesn’t require blockchain nodes to perform arduous, and otherwise useless, cryptographic tasks in order to render potential attacks costly and infeasible. Hence, this algorithm cuts the power requirements of PoS blockchains down to sane and manageable amounts, allowing them to be more scalable without guzzling up the planet's energy reserves.
As the name suggests, instead of requiring proof of cryptographic work, PoS requires blockchain nodes to proof stake in the currency itself. This means that in order for a blockchain node to be eligible for a verification reward, the node has to hold a certain amount of currency in the wallet associated with it. This way, in order to execute an attack, a malevolent node would have to acquire the majority of the existing coin supply, rendering attacks not only costly but also meaningless, since the attackers would primarily harm themselves.
PoS, as well as PoW, simply cause the blockchain to fork into two alternative versions if for some reason consensus breaks. In fact, most blockchains fork most of the time, only to converge back to a single source of truth a short while afterwards.
By many crypto enthusiasts, this obvious bug is very often regarded as a feature, allowing several versions of the truth to survive and compete for public adoption until a resolution is generated. This sounds nice in theory, but if we want to see blockchain technology seriously disrupt and/or augment the financial sector, this ever lurking possibility of the blockchain splitting into two alternative versions cannot be tolerated.
Furthermore, even the fastest PoS blockchains out there can accomodate a few hundred transactions per second, compare that to Visa’s 56,000 tx/s and the need for an alternative becomes clear as day.
A blockchain securing global stock markets does not have the privilege to fork into two alternative versions and just sit and wait it out until the market (or what’s left of it) declares a winner. What belongs to whom should be engraved in an immutable record, functioning as a single source of truth with no glitches permitted.
After investigating and studying the crypto industry and blockchain technologies for several years, we came to the conclusion that the delegated Byzantine Fault Tolerance alternative (or dBFT) is best suited for such a system. It provides swift transaction verification times, de-incentivises most attack vectors and upholds a single blockchain version with no risk of forks or alternative blockchain records emerging - regardless of how much computing power, or coins an attacker possesses.
The term Byzantine Fault Tolerance (BFT) derives its name from the Byzantine Generals problem in Game Theory and Computer Science, describing the problematic nature of achieving consensus in a distributed system with suboptimal communication between agents which do not necessarily trust each other.
The BFT algorithm arranges the relationship between blockchain nodes in such a way that the network becomes as good as resilient to the Byzantine Generals problem, and allows the system to remain consensus even if some nodes bare malicious intentions or simply malfunction.
To achieve this, Antshare’s version of the delegated BFT (or dBFT) algorithm acknowledges two kinds of players in the blockchain space: professional node operators, called bookkeeping nodes, who run nodes as a source of income, and users who are interested in accessing blockchain advantages. Theoretically, this differentiation does not exist in PoW and most PoS environments, practically, however, most Bitcoin users do not operate miners, which are mostly located in specialized venues run by professionals. At Antshares we understand the importance of this naturally occurring division of labor and use it to provide better security for our blockchain platform.
Accordingly, block verification is achieved through a consensus game held between specialized bookkeeping nodes, which are appointed by ordinary nodes through a form of delegated voting process. In every verification round one of the bookkeeping nodes is pseudo-randomly appointed to broadcast its version of the blockchain to the rest of the network. If ⅔ of the remaining nodes agree with this version, consensus is secured and the blockchain marches on. If less than ⅔ of the network agrees, a different node is appointed to broadcast its version of the truth to the rest of the system, and so forth until consensus is established.
In this way, successful system attacks are almost impossible to execute unless the overwhelming majority of the network is interested in committing financial suicide. Additionally, the system is fork proof, and at every given moment only one version of the truth exists. Without complicated cryptographic puzzles to solve, nodes operate much faster and are able to compete with centralized transaction methods.

OnChain

 
It is important to note the technical difference between Onchain and NEO. Onchain is a private VC-backed company with over 40 employees. NEO is a public platform with different community-led groups contributing to this public project. There exists NEO council comprised of the original NEO creators, employees from Onchain, full time NEO council members and there is also the first Western based group called City of Zion.
Onchain, a Shanghai-based blockchain R&D company, first started developing Antshares in February of 2014 which will eventually become the foundation of DNA. Onchain was founded by CEO Da HongFei and CTO Erik Zhang in response to the attention from private companies garnered by the development of Antshares, China’s first public blockchain. In contrast to the weeks-old start-ups launching ICOs that is happening currently in the blockchain world, it took them 22 long months of R&D to even begin providing services to their first customers. Finally, in April 2016, the first whitepaper on consensus protocol from China was born — the dBFT (delegated Byzantine Fault Tolerance) protocol.
2016 was a busy year for Onchain and they really picked up the pace that year. Other than continuing the development of Antshares, brushing shoulders with Fortune 500 companies, Onchain became the first Chinese blockchain company to join Hyperledger — an open source blockchain project started by the Linux Foundation specifically focusing on the development of private and consortium chains for businesses.
In June of 2016, during the first of many future partnerships with Microsoft China, Onchain founded Legal Chain specifically targeting the inadequacies of the digital applications within the legal system. In 2005, (Digital Signature Act) was passed into national law which permitted an effective digital signatures to gain the same legal rights as a real signature.
In company with Microsoft China, they are also aiming to integrate the technology with Microsoft’s face and voice recognition API function to kick start this digital revolution within the legal system. At the same time, a partnership was formed with FaDaDa, a third-party platform for electronic contracts that has processed over 27 million contracts to date, to provide secure evidence storage with DNA. If that’s not enough, they were also voted as KPMG’s top 50 Fintech Company in China and established a relationship with the Japanese Ministry of Economy, Trade and Industry which led to the recent tour to Japan. Finally, at the end of 2016 they announced a partnership with Alibaba to provide attested email service for Ali Cloud with Legal Chain where it provides a proof-of-existence for a blockchain-powered email evidence repository for enterprise-level use.
Fosun Group, China’s largest private conglomerate, have recently invested into Onchain in order to apply DNA across all of its businesses. Currently, Fosun International has a market cap of 102.98 billion dollars on the Hong Kong Stock Exchange and that is only its international branch.
The role of Onchain so far is reminiscent of Ethereum’s EEA in addition to a stronger emphasis of governmental cooperation. Onchain has identified the shortcomings of present laser focus of hype on public platforms such as NEO and Ethereum and addressing that with DNA. DNA envisions a future where a network of assorted, specifically designed blockchains serving private enterprises, consortiums, government and the public communicating with each other forming an interconnected blockchain network.
This is the goal of DNA — infiltrating every little inefficient niche that had no better alternatives before the invention of blockchain. What is especially critical to remember during this explosive time of hype driven partly by the obscene degree of greed is that not every little niche that blockchain can fill will be holding its own little ICO. Some of those efficiencies gained will simply be consumed by companies privately or by public systems such as the legal system.

Networks proves itself with the first ICO

 
ICOs, on other platforms such as Ethereum, often resulted in a sluggish network and transaction delays. While NEO’s dBFT consensus algorithm is designed to achieve consensus with higher efficency and greater network throughputt, no amount of theoretical calculations can simulate the reality of real-life conditions.
 

Key Observations

 
Smart Contract Invocations:
A total of 13,966 smart contracts invocations were executed on the NEO network over this time period, of which, nearly all called the RPX smart contract method mintTokens. A total of 543,348,500 RPX tokens were successfully minted and transferred to user accounts, totalling 10,097 smart contract executions.
 
Refunded Invocations:
A total of 4182 refund events were triggered by the smart contract method mintTokens. (Note: RPX has stated that these refunds will be processed within the next two weeks.)
 
Crowdsale Statistics:
A successful mintTokens execution used around 1043 VM operations, while an execution that resulted in a refund used 809 VM operations. Within the hour and six minutes that the token sale was active, a total of 12,296,409 VM operations were executed. A total of 9,575 unique addresses participated in the RPX ICO. Half of these, approximately 4,800 unique addresses, participated through CoZ’s Neon wallet. The top 3 blocks with the most transactions were block 1445025 (3,242 transactions), block 1444902 (2,951 transactions), and block 1444903 (1609 transactions).
 
Conclusion on Network Performance
At the moment, the consensus nodes for the NEO network are operated by the NEO Council in China. By Q1 2018, NEO Council aims to control less than two-thirds of the consensus nodes.
We are pleased to note that the NEO network continuted to operate efficiently with minimal network impact, even under extreme network events. Block generation time initially slowed down to 3 minutes to process the largest block, but quickly recovered to approximately 25 seconds. Throughout the entire RPX ICO, consensus nodes were able to achieve consensus and propagate new block transactions to the rest of the network. In closing, while we consider this performance to be excellent, NEO Council and City of Zion areworking closely together on upgrades, that will increase the throughputs of the NEO network.
 

Hyperledger

 
Members and governance of Hyperledger:
Early members of the initiative included blockchain ISVs, (Blockchain, ConsenSys, Digital Asset, R3, Onchain), well-known technology platform companies (Cisco, Fujitsu, Hitachi, IBM, Intel, NEC, NTT DATA, Red Hat, VMware), financial services firms (ABN AMRO, ANZ Bank, BNY Mellon, CLS Group, CME Group, the Depository Trust & Clearing Corporation (DTCC), Deutsche Börse Group, J.P. Morgan, State Street, SWIFT, Wells Fargo), Business Software companies like SAP, Systems integrators and others such as: (Accenture, Calastone, Credits, Guardtime, IntellectEU, Nxt Foundation, Symbiont).
The governing board of the Hyperledger Project consists of twenty members chaired by Blythe Masters, (CEO of Digital Asset), and a twelve-member Technical Steering Committee chaired by Christopher Ferris, CTO of Open Technology at IBM.

Upcoming Roadmap

 
Decentralization of consensus nodes
▪ P2P Network optimization – Network optimizations to ensure fast block generation after decentralization.
▪ Voting Algorithm Optimization – Adjustments in voting algorithm to prevent identified attack vectors.
▪ Candidate List Website – Published list of candidates so that voters know who they are voting for.
▪ NEO Council Consensus Node < 2/3 – NEO Council shall operate less than two thirds of consensus nodes by the end of quarter 1, 2018.
 
Our original plan was to start decentralize in Q1 2018. We are however growing faster than expected and cannot accept the risk with being as centralized as we currently are. The conclusion is that we re-prioritize and start the process of decentralizing today. We believe that NEO community groups and exchanges will be suitable to run consensus nodes; community groups already know the technology, and exchanges are already running full nodes with high uptime and monitoring. We welcome interested parties to reach out to us on [email protected]. A NEP to encourage voting will be presented in the coming weeks.
https://neo.org/blog/Details/3016
 
Universal Data Format for Wallet/Node Prog.
▪ NEP2 – Private Key Encryption/Decryption (2017Q4) - Method for encrypting and encoding a passphrase-protected private key.
▪ NEP3 – Universal Data Format (2017Q4) – Standard data format to allow easier wallet and node programming.
https://neo.org/en-us/blog/details/65
 
Promotion/Ecosystem
▪ Globally Legal Token-raising Framework (2017Q4) – Following government interest to regulate ICO’s, NEO will complete a framework to raise tokens legally in all major markets by the end of 2017.
▪ NEO DevCon 1 (2017Q4) – First NEO Development Conference! More details at later date.
▪ CoZ Funding (2017Q4) – Continuous funding plan for CoZ covering next 5 years.
▪ Seed Projects (2017Q4) – First seed projects to be cross-invested with the dedicated NEO pool.

I decided to post this here as I saw some questions on the QRL discord.

Is elliptic curve cryptography quantum resistant?
No. Using a quantum computer, Shor's algorithm can be used to break Elliptic Curve Digital Signature Algorithm (ECDSA). Meaning: they can derive the private key from the public key. So if they got your public key, they got your private key, and they can empty your funds. https://en.wikipedia.org/wiki/Elliptic-curve_cryptography#Quantum_computing_attacks https://eprint.iacr.org/2017/598.pdf
Why do people say that BTC is quantum resistant, while they use elliptic curve cryptography? (Here comes the idea from that never reusing a private key from elliptic curve cryptography (and public key since they form a pair) would be quantum resistant.)
Ok, just gonna start with the basics here. Your address, where you have your coins stalled, is locked by your public- private key pair. See it as your e-mail address (public key) and your password (Private key). Many people got your email address, but only you have your password. If you got your address and your password, then you can access your mail and send emails (Transactions). Now if there would be a quantum computer, people could use that to calculate your password/ private key, if they have your email address/ public key.
What is the case with BTC: they don't show your public key anywhere, untill you make a transaction. So your public key is private untill you make a transaction. How do they do that while your funds must be registered on the ledger? Wel, they only show the Hash of your public key (A hash is an outcome of an equation. Usually one-way hash functions are used, where you can not derive the original input from the output. But everytime you use the same hash function on the same original input (For example IFUHE8392ISHF), you will always get the same output (For example G). That way you can have your coins on public key IFUHE8392ISHF, while on the chain, they are on G.) So your funds are registered on the blockchain on the "Hash" of the public key. The Hash of the public key is also your "email address" in this case. So you give "G" as your address to send BTC to.
By the way, in the early days you could use your actual public key as your address. And miners would receive coins on their public key, not on the hashed public key. That is why all the Satoshi funds are vulnerable to quantum attacks even though these addresses have never been used to make transactions from. These public keys are already public instead of hashed. Also certain hard forks have exposed the public keys of unused addresses. So it's really a false sense of security that most people hang on to in the first place.
But it's actually a false sense of security over all.
Since it is impossible to derive a public key from the Hash of a public key, your coins are safe for quantum computers as long as you don't make any transaction. Now here follows the biggest misconseption: Pretty much everyone will think, great, so BTC is quantum secure! It's not that simple. Here it is important to understand two things:
1 How is a transaction sent? The owner has the private key and the public key and uses that to log into the secured environment, the wallet. This can be online or offline. Once he is in his wallet, he states how much he wants to send and to what address.
When he sends the transaction, it will be broadcasted to the blockchain network. But before the actual transaction that will be sent, it is formed into a package, created by the wallet. This happens out of sight of the sender.
That package ends up carrying roughly the following info: The public key to point to the address where the funds will be coming from, the amount that will be transferred, the public key of the address the funds will be transferred to.
Then this package caries the most important thing: a signature, created by the wallet, derived from the private- public key combination. This signature proves to the miners that you are the rightfull owner and you can send funds from that public key.
So this package is then sent out of the secure wallet environment to multiple nodes. The nodes don’t need to trust the sender or establish the sender’s "identity." And because the transaction is signed and contains no confidential information, private keys, or credentials, it can be publicly broadcast using any underlying network transport that is convenient. As long as the transaction can reach a node that will propagate it into the network, it doesn’t matter how it is transported to the first node.
2 How is a transaction confirmed/ fullfilled and registered on the blockchain?
After the transaction is sent to the network, it is ready to be processed. The nodes have a bundle of transactions to verify and register on the next block. This is done during a period called the block time. In the case of BTC that is 10 minutes.
If you comprehend the information written above, you can see that there are two moments where you can actually see the public key, while the transaction is not fullfilled and registered on the blockchain yet.
1: during the time the transaction is sent from the sender to the nodes
2: during the time the nodes verify the transaction.
This paper describes how you could hijack a transaction and make a new transaction of your own, using someone elses address to send his coins to an address you own during moment 2: the time the nodes verify the transaction:
https://arxiv.org/pdf/1710.10377.pdf
"(Unprocessed transactions) After a transaction has been broadcast to the network, but before it is placed on the blockchain it is at risk from a quantum attack. If the secret key can be derived from the broadcast public key before the transaction is placed on the blockchain, then an attacker could use this secret key to broadcast a new transaction from the same address to his own address. If the attacker then ensures that this new transaction is placed on the blockchain first, then he can effectively steal all the bitcoin behind the original address."
So this means that practically, you can't call BTC a quantum secure blockchain. Because as soon as you will touch your coins and use them for payment, or send them to another address, you will have to make a transaction and you risk a quantum attack.
Why would Nexus be any differtent?
If you ask the wrong person they will tell you "Nexus uses a combination of the Skein and Keccak algorithms which are the 2 recognized quantum resistant algorithms (keccal is used by the NSA) so instead of sha-256, Nexus has SK-1024 making it much harder to break." Which would be the same as saying BTC is quantum resistant because they use a Hashing function to hash the private key as long as no transaction is made.
No, this is their sollid try to be quantum resistant: Nexus states it's different because they have instant transactions (So there wouldn't be a period during which time the nodes verify the transaction. This period would be instant.) Also they use a particular order in which the miners verify transactions: First-In-First-Out (FIFO) (So even if instant is not instant after all, and you would be able to catch a public key and derive the private key, you would n't be able to have your transaction signed before the original one. The original one is first in line, and will therefore be confirmed first. Also for some reason Nexus has standardized fees which are burned after a transaction. So if FIFO wouldn't do the trick you would not be able to use a higher fee to get prioritized and get an earlyer confirmation.
So, during during the time the nodes verify the transaction, you would not be able to hijack a transaction. GREAT, you say? Yes, great-ish. Because there is still moment # 1: during the time the transaction is sent from the sender to the nodes. This is where network based attacks could do the trick:
There are network based attacks that can be used to delay or prevent transactions to reach nodes. In the mean time the transactions can be hijacked before they reach the nodes. And thus one could hijack the non quantum secure public keys (they are openly included in sent signed transactions) who then can be used to derive privatekeys before the original transaction is made. So this means that even if Nexus has instant transactions in FIFO order, it is totally useless, because the public key would be obtained by the attacker before they reach the nodes. Conclusion: Nexus is Nnot quantum resistant. You simply can't be without using a post quantum signature scheme.
Performing a DDoS attack or BGP routing attacks or NSA Quantum Insert attacks on a peer to peer newtork would be hard. But when provided with an opportunitiy to steal billions, hackers would find a way. For example:
https://bitcoinmagazine.com/articles/researchers-explore-eclipse-attacks-ethereum-blockchain/
For BTC:
https://eprint.iacr.org/2015/263.pdf
"An eclipse attack is a network-level attack on a blockchain, where an attacker essentially takes control of the peer-to-peer network, obscuring a node’s view of the blockchain."
That is exactly the receipe for what you would need to create extra time to find public keys and derive private keys from them. Then you could sign transactions of your own and confirm them before the originals do.
By the way, yes this seems to be fixed now, but it most definately shows it's possible. And there are other creative options. Either you stop tranasctions from the base to get out, while the sender thinks they're sent, or you blind the network and catch transactions there. There are always options, and they will be exploited when billions are at stake. The keys can also be hijacked when a transaction is sent from the users device to the blockchain network using a MITM attack. The result is the same as for network based attacks, only now you don't mess with the network itself. These attacks make it possible to 1) retrieve the original public key that is included in the transaction message. 2) Stop or delay the transaction message to arrive at the blockchain network. So, using a quantum computer, you could hijack transactions and create forged transactions, which you then send to the nodes to be confirmed before the nodes even receive the original transaction. There is nothing you could change to the Nexus network to prevent this. The only thing they can do is implement a quantum resistant signature scheme. They plan to do this in the future, like any other serious blockchain project. Yet Nexus is the only of these future quantum resistant projects to prematurely claim to be quantum resistant. There is only one way to get quantum resistancy: POST QUANTUM SIGNATURE SCHEMES. All the rest is just a shitty shortcut that won't work in the end.
(If you use this info on BTC, you will find that the 10 minutes blocktime that is used to estimate when BTC will be vulnerable for quantum attacks, can actually be more then 10 minutes if you catch the public key before the nodes receive them. This makes BTC vulnerable sooner thatn the 10 min blocktime would make you think.)
By the way, Nexus using FIFO and standadrized fees which are burned after the transaction comes with some huge downsides:
Why are WOTS+ signatures (and by extension XMSS) more quantum resistant?
First of all, this is where the top notch mathematicians work their magic. Cryptography is mostly maths. As Jackalyst puts it talking about post quantum signature schemes: "Having papers written and cryptographers review and discuss it to nauseating levels might not be important for butler, but it's really important with signature schemes and other cryptocraphic methods, as they're highly technical in nature."
If you don't believe in math, think about Einstein using math predicting things most coudldn't even emagine, let alone measure back then.
Then there is implementing it the right way into your blockchain without leaving any backdoors open.
So why is WOTS+ and by extension XMSS quantum resistant? Because math papers say so. With WOTS it would even take a quantum computer too much time to derive a private key from a public key. https://en.wikipedia.org/wiki/Hash-based_cryptography https://eprint.iacr.org/2011/484.pdf
What is WOTS+?
It's basiclally an optimized version of Lamport-signatures. WOTS+ (Winternitz one-time signature) is a hash-based, post-quantum signature scheme. So it's a post quantum signature scheme meant to be used once.
What are the risks of WOTS+?
Because each WOTS publishes some part of the private key, they rapidly become less secure as more signatures created by the same public/private key are published. The first signature won't have enough info to work with, but after two or three signatures you will be in trouble.
IOTA uses WOTS. Here's what the people over at the cryptography subreddit have to say about that:
https://www.reddit.com/crypto/comments/84c4ni/iota_signatures_private_keys_and_address_reuse/?utm_content=comments&utm_medium=user&utm_source=reddit&utm_name=u_QRCollector
With the article:
http://blog.lekkertech.net/blog/2018/03/07/iota-signatures/
Mochimo uses WOTS+. They kinda solved the problem: A transaction consists of a "Source Address", a "Destination Address" and a "Change Address". When you transact to a Destination Address, any remaining funds in your Source Address will move to the Change Address. To transact again, your Change Address then becomes your Source Address.
But what if someone already has your first address and is unaware of the fact you already send funds from that address? He might just send funds there. (I mean in a business environment this would make Mochimo highly impractical.) They need to solve that. Who knows, it's still a young project. But then again, for some reason they also use FIFO and fixed fees, so there I have the same objections as for Nexus.
How is XMSS different?
XMSS uses WOTS in a way that you can actually reuse your address. WOTS creates a quantum resistant one time signature and XMSS creates a tree of those signatures attached to one address so that the address can be reused for sending an asset.

microhash - 06/28/2018 Thanks for the advice, guys. Already told eric that I'm interested, now it's up to the IF.
dom - Today at 3:04 AM no, we do not work with Bosch on Jinn
Fahad Sheikh - Today at 3:14 AM There is a lot to look forward to, didn't ya'll see the Project List that Edward posted in Medium? Coordicide being the most interesting one IMO.
Come-from-Beyond - Today at 6:34 AM [bro which company will manufacture the jinn processors] Nvidia, joke :trollcfb:
Eric Hop - Today at 5:10 AM If you are thinking there isn't much response from IF on Discord at the moment: we're all together at a summit working closely together. We're doing team building (we're from all over the globe) and work shops. Cross team presentations. And working in research groups to boost most projects forward.
7/20
David Sønstebø - Today at 1:27 AM The lightweight trinary hashfunction that IOTA set out to create with the Curl-P project will indeed be created by world leading cryptographers who specialize in exactly this field within cryptography. and yes, this has begun.
7/27
Ralf RottmannLast Monday at 5:53 PM 1.) IOTA Foundation has been very clear about the importance of manual tethering and that understanding deployment topologies will be an ongoing research topic. IOTA Foundation has also made clear, that better support for finding neighbours is a topic under active research. As the current status clearly shows, the solution is not as simple as what Nelson brings to the table. So in essence, Nelson forces IOTA Foundation to shift priorities. These things happen all the time and we are not that worried about it. We knew this ride wouldn't be easy!
2.) In an open source, permissionless environment, Roman and his team do not have to ask for permission and do not have to cooperate with anybody. They can do whatever they think might be valuable for the community, the network and its many different stakeholders. It will always be up to the users and various parties who are having an interest into the technology, to decide whether they see value being added or damage done. There is no objective judge empowered to decide. On the contrary, everyone is entitled to freely voice praise, concerns and opinion at any time.
3.) It already is public knowledge, that IOTA Foundation has been discussing ways to actively collaborate with Roman and his team a while ago but we couldn't agree around technicalities and commercials and ultimately mutually decided, that it would help the community at large, if Roman and his team stay completely independent and IOTA Foundation continues its research and development, with network topology just being a tiny part of the grand vision.
4.) Roman has publicly stated, that he is not interested in forking the project and only wants to do good for IOTA. I personally appreciate him being very clear about this, because it takes away uncertainty and speculation and I trust Roman to be genuinely honest with us. It does, however, come with the territory, that forks might happen at any time. I personally do not worry that much, should we ever see an attempt from anybody to embark on a fork. My decision to follow such an undertaking (with time, effort and money), would always be based on the likelihood of the effort to having enough funds to exist long-term. IOTA is not just about a network of nodes. Bringing the complete vision to life is an enormous effort, that will take years to come, the commitment of large corporate and public partners and affording a strong global team, to holding the pieces together. I have seen many similar initiatives failing. So far, IOTA Foundation has done very well and I'm confident we're just getting started. I hope this somewhat sets the record straight for what I've been stating on Twitter and elsewhere!
dom Last Monday at 4:01 AM sidetangles are something that we are actively researching right now with a university. Quite frankly, at the current stage, they serve little purpose on the mainnet for any of our use cases or products we intend to build.
dom Last Monday at 4:02 AM I'm not sure if they will be disabled by this fix entirely - I don't think so. But I will let our engineers answer that.

David Sønstebø 07/20/2018 [Any news about IOTA and the e-krona in the past weeks? ] Nothing to report right now, in Scandinavia it is summer vacation
David Sønstebø Last Wednesday at 4:43 AM [any information about work with partners, like VW, Cisco, Schindler.... etc] @DvorNick When it comes to updates with organizations we work with, it is equally in their hands. It's unfortunately an incredibly tedious process, the people we work with are excited to get news out, but they have to jump through 10 hoops to get it approved
David Sønstebø Last Wednesday at 4:52 AM 1) If the community had to choose, what do you want: founders and Foundation members that can communicate in a friendly, transparent and open fashion, including the candid joking chats or shadows in ivory towers with personality cults?
2) I refuse to believe CfB has ever said: "I guarantee the price will be X"
Our vision, our status updates etc. are 100% honest. That's what you need to focus on. We don't cater to speculators, we just put the truth out there, then you can interpret and speculate as you want
Come-from-Beyond Last Wednesday at 4:55 AM I just said that IOTA will be #1 on CMC
Come-from-Beyond Last Wednesday at 4:55 AM roughly 5 months left
David Sønstebø Last Wednesday at 4:58 AM @Ryan G. 100%. 6 degrees of separation is no joke. For IF right now it's more about quality over quantity, we got way more demand than we can supply, but there's certainly a few things that will come to mind
David Sønstebø Last Wednesday at 5:08 AM [You have selected great advisors for IF, well done! question: how do you work with them in the organisation?] @ets Thanks. It differs from person to person, some we are working with on a nearly daily basis, others we speak with once a week about the bigger picture, or more actively within a certain project
Ralf Rottmann Last Monday at 5:07 PM @Th3B0Y We are actively engaging with Eclipse Foundation. They have governance figured out for large projects like ours.
Ralf Rottmann Last Monday at 5:15 PM [will IF always decide, for example, what changes and what doesn't on IRI?] @Th3B0Y No. That's exactly what Eclipse Foundation will bring to the table. It has clearly outlined and well established processes around these things and will help us to bring in large contributors (like corporate partners) down to individuals. We are already engaging with key partners who are keen to help contributing to our code base. Moving under Eclipse Foundation involves some complex legal matters around trademarks, which is why we are not "just doing it" right away.
Ralf Rottmann Last Monday at 5:22 PM [ if the IF doesn't want something to change/be added but many devs want, will it be "merged" anyway? or will they simply have to fork it?] @Th3B0Y There will be a process around it with IOTA Foundation not having sort of the ultimate power. That was never our intention. It's just required at the early stage we're at. –– Of course, everybody can decide to fork at any time and everyone can decide to go with a fork. I personally would make such a decision primarily based on the likelihood of any fork to having enough funds for supporting an undertaking as big as the IOTA vision. We have to keep it mind, it's not just about setting up a basic network! (Something we tend to forget.)

Ralf Rottmann Last Tuesday at 12:11 AM Sergey Ivancheglo is a honorary member & founder. He is not legally employed by IOTA Foundation, as many others. CfB developed the first version of COO. IOTA Foundation runs and operates COO instances and has full access to the source code.
Edward Greve Last Tuesday at 12:58 AM [CFB is creating a significant portion of Tangles technology] @Deep_Sea_Hopper Not since 2016
Edward Greve Last Tuesday at 12:58 AM CFB hasn't contributed to IRI (or any other IF maintained repo) to my knowledge since then
Edward Greve Last Tuesday at 1:02 AM Ict, at the moment, is being worked on by CFB alone. We (IF) have seen the code, but are not working on it until he's "done" with it and then gives it to us to fix / polish / improve and release publicly. The same thing happened with IRI ~2 years ago...
Ralf RottmannLast Tuesday at 1:07 AM @Deep_Sea_Hopper For the sake of completeness and because it has been said before: We were considering working with Roman's team but the technicalities and commercials haven't worked out. We are confident, that our very own teams will figure out a solution while at the same time spending our funds in line with our charitable, non-profit boundaries. -- There are some good news in this: We all seem to be completely aligned about the various problem statements. The various parties can now start working on fixes.
Edward GreveLast Tuesday at 1:15 AM He is saying that Ict represents the swarm nodes, and doesn't expect them to work in the current mainnet environment due to his assumption that the Ict nodes and autopeered nodes will form separate clusters, with the vast majority of transactions happening outside of the Ict cluster.
Edward GreveLast Tuesday at 1:21 AM Ideally, we would have a well-researched auto peering solution, which answers all of the open questions. I don't see it happening that quickly though. It's a complex problem.
Ralf RottmannLast Tuesday at 3:31 AM @lluisin I have explained it before: We did take a thorough look at Nelson and decided, that we leverage our engineering team, to address the problem of automatic peering. As a charitable non-profit foundation (sorry for constantly reminding everyone of this), we need to pick carefully, where we spend money. We currently cannot justify to enhance a "product" that we ultimately do not believe in as a solution to a core challenge. As towards collaboration with Roman in a professional capacity, we did discuss this openly with him and his brother but couldn't agree on the technicalities and commercials.
Ralf RottmannLast Tuesday at 3:39 AM Applied to what Roman and his team do, this means we can't invest into Field, which is not yet open source and not developed in the open. Same is true for Hercules. We could potentially invest into Nelson but don't think it's solving the problem the right way. We haven't done an exhaustively deep analysis. We haven't prepared a laundry list of points, that Roman and his team could work upon to make Nelson better. Nelson is not our product. We don't believe in it. Hence we're not "wasting" the Foundation's time and money on improving it. We (have to) live with the consequences it causes and instead ramp up our own efforts to eliminate the root issues. Thanks to the many donors who believe in the project, we have the funds to work on this for years to come and are confident that time and dedication will bring us there.
Ralf RottmannLast Tuesday at 3:46 AM I absolutely understand that humans tend to jump on apparent short term fixes and it's extremely difficult to stay patient. And there is one other aspect: Workarounds like Nelson constantly challenge the network and our basic assumptions. They help surfacing what we don't know. It's not always fun, but it certainly helps driving IOTA forward! So we are eternally grateful for having Roman and every other community developer around. We also believe, there are vast commercial opportunities for the community in IOTA. Spending Foundation money on those just is a totally different story. For the Semko brothers there is absolutely nothing to worry about. There also is no attitude. I think this very open debate is a testament to exactly that. The community has asked for more transparency. We hopefully have established that. Since my very first day in this community, I always said what I mean. You can either ask for my honest opinion or should not ask me. It would have been way easier to respond with some generic paragraph about how much we appreciate every contribution and move on. The fact of the matter is: We are all in this together for a multitude of different reasons. That is what makes IOTA so fascinating. As the only party, who is a regularly audited charitable non-profit, we are legally required to make all of our decisions transparent. Hence we sometimes cannot rush out fixes, release untested software or do quick investment decisions. When the IOTA founders chose a non-profit foundation, they did so for a reason. One thing everyone can be absolutely assured at any time: IOTA Foundation is not in this for any commercial purposes. It has no shareholders. No beneficiaries. No owners. It is owned by itself. That's a major advantage. (And also, why I'm not at all nervous about the potential of any forks. Going with a fork that's not governed as a charitable non-profit would be borderline stupid.)
Ralf RottmannLast Tuesday at 4:07 AM Getting back to Nelson: As Roman stated earlier, we had Mathew Yarger looking into Nelson. We do plan to send our findings and questions to Roman by the end of the week. Out of respect, I would leave it up to Roman whether he wants to share publicly and to which extend he sees value in keeping the community updated about our interaction.
Come-from-BeyondLast Tuesday at 4:53 AM I'm back guys, has anyone reviewed my claim that current Nelson's strategy contradicts to what was recommended in that paper about reaching consensus? (https://www3.nd.edu/~mhaenggi/pubs/jstsp11.pdf)
Ralf RottmannLast Tuesday at 5:04 AM [Okay so the lower rotation frequence creates wormholes? ] @PatriQ That’s actually the entire point. It’s a hard problem to solve. Needs research. Thoroughly reading relevant papers. Rushing out a workaround and hoping it “just works” is not the way the foundation can handle things. And we take the liberty to occasionally highlight this aspect.
Come-from-BeyondLast Tuesday at 5:04 AM [Okay so the lower rotation frequence creates wormholes?] Higher rotation frequency does. Also make sure that you have not more than 3 active neighbors with manual tehtering we use 5-7 assuming that some neighbors will die
PatriQLast Tuesday at 5:06 AM Okay so we figured out couple of points: 1# Higher rotation frequency creates wormholes. 2# Max 5-7 neighbors (thats included with Nelson) What else?
Ralf RottmannLast Tuesday at 5:16 AM @Deep_Sea_Hopper We did an analysis and Roman is in touch with Mat.
Come-from-BeyondLast Tuesday at 5:42 AM @PatriQ 2# Max 5-7 neighbors (thats included with Nelson) 3 neighbors if Nelson is used (assuming those neighbors are active ones)
David SønstebøLast Tuesday at 9:34 AM Today has been an interesting one. Some topics need to be clarified right away: The IOTA Foundation is 100% supportive of any third party actors such as the Semko brothers, the IOTA project is an open and permissionless one; therefore everyone has the right to develop on top of it. In fact, the entire IOTA project is dependent on it. Independent entities, whether big or small, getting involved and developing in conjunction with or independent of the IOTA Foundation is a mantra we have been preaching since the very inception of IOTA. It is the vision we still have for the future of IOTA. As an open source project, this is crucial for success. Another vital aspect is a drastic improvement in communication, bilaterally between IF and third parties, as well as in general to the broader community. We are happy to say that this is the number one priority of the foundation at the moment. We know that people can become confused and begin to speculate, rightfully so, when there is a vacuum in communication. If something is going on with the network that we have not communicated beforehand, then Fear, Uncertainty and Doubt kicks in. What we are working on right now is weekly newsletters, weekly update blog posts on certain days, and a roadmap that is continually up to date, that will give everyone a clear insight into where the different projects are, both from development and research perspectives, as well are defined ETAs. The IOTA community is a smart and driven one, but no one can be expected to predict the future or read our minds; therefore it is incumbent upon the IOTA Foundation to communicate in a fashion that gives people predictable roadmaps and status updates to avoid excessive worrying. Finally, everyone should feel absolutely free to raise their opinions and ask whatever questions they feel like. At the end of the day we are all in this together, and while the work being conducted by IF now is more efficient and focused than ever before, it is ultimately our responsibility that this is reflected in our communication and thus permeates the attitude of the project overall.

domYesterday at 5:27 PM network protocol and syncing is something we are looking deeper right now. But the network layer is the number one bottleneck of IOTA right now.
domYesterday at 5:50 PM waiting on the Desktop release, then we will work on the Ledger integration. but the community already did a fantastic job there
domYesterday at 5:51 PM yeh, Trinity Desktop will be amazing I really want to see an IOTA App Marketplace evolve around that, where people can then test various use cases. Like the TipBot, secure audit trails, timestamping documents, paying for storage etc. it can become a gateway for a sort of sandbox environment, where you can try these apps out and just contribute through that (experimenting with new IOTA-based apps).
domYesterday at 6:02 PM btw, I think IOTA is one of the few projects where the community is contributing a lot of great development, making this really a more decentralized ecosystem. Ethereum has that, and maybe Bitcoin, but I don't know of any other project that has fully working core clients, libraries ,node deployment scripts and services (like the tipbot) like we do
domYesterday at 6:43 PM [I was quoting David a few months ago where target was > 100 CTPS EOY 18] we still aim for that
domYesterday at 6:48 PM [wasn't the tangle taken down regularly by attackers even with the COO? How is a large corp going to commit?] we have a technical roadmap and we stick to that - this includes achieving the KPI's mentioned above. Right now we have to resolve a lot of technical debt from previous years, but we are quickly catching up and making IRI more robust. Private Tangles are great for corporates to experiment right now.
Ralf RottmannYesterday at 3:49 AM I understand the rationale behind it but don’t like how the idea, once people get used to it, might pave the way to transaction-fees. Of course everyone can built businesses on top of IOTA and that is a huge part of building an ecosystem. I just wouldn’t personally endorse the idea to prioritize value tx at this stage of the project. Not meant as an offense!
Roman SemkoYesterday at 4:06 AM Not taken as offence, @Ralf Rottmann ! We are all grown ups to discuss this in a civilized manner. I am not intending to keep this tipsel algo. It is just one temporary node targeting to solve current bottleneck. Nothing more. I am of the same opinion as you on this one.
Ralf RottmannYesterday at 4:08 AM Thanks, @Roman Semko. May I cross-post this to twitter? People seem to somehow think the two of us are enemies... I plan to add Hercules nodes to IOTA.FM over the weekend. If that doesn’t prove otherwise, I don’t know!
