Node Block Count Discrepancy

Node Block Count Discrepancy
Hi All, I wasn't sure where to post this or who to ask so I'm putting out to the community to see if anyone here may know what exactly is happening. As of about a minute ago I noted a large discrepancy between my person node's count vs. what blockstream dot com is show as far as the bitcoin block height (it said 630734 vs. my 630732). To me there should not be a 2 block delta but I'm not the expert there. Do anyone here know how or why this would be the case? It seems quite concerning to me. Thanks in advance for you help here~

removed screen shot and my block is now in synch. Thanks to all who commented.

The First Handshake

On the 615817th Bitcoin block height, the BTC blockhash will be committed into the Handshake genesis block. While it can be immediately mined, the genesis block is only locked in after six confirmations. After the first six confirmations of valid Bitcoin blocks with the genesis block will not change even with a deep reorg. The code will be available for download on February 1, 2020.

Written by Steven M.

To help understand the upcoming Bitcoin SC hard fork, this article will compare the hard forks for Bitcoin Cash (ABC) and Bitcoin Satoshi Vision, review the technical approach and parameters for these forks, and compare with Bitcoin SC’s approach.

Intro to Hard Forks


Blockchain hard forks happen when protocol or consensus rules are updated in node software to produce blocks and transactions that are not compatible with non-updated versions of nodes. This is generally described as the software not being “backward compatible” which is a bit of a misnomer, since the new version nodes are compatible with older blocks and transactions, thus preserving the full history of a blockchain. Node software enforces the protocol change at a block height certain. What is incompatible after a hard fork is the blocks going forward. After a hard fork, the blockchain is split and exists as two blockchains with separate characteristics.

For “consensus” hard forks, where the community agrees on the updates to a blockchain, a single “official” new blockchain will continue after the hard fork, and perhaps a split chain for laggards who didn’t update in time. However, if there is developer support for both chains after a hard fork, and technology — business — community interest in supporting two versions of the blockchain, the hard fork will give two blockchains going forward.

This report compares three blockchain splits from hard forks which are shown schematically below.

https://preview.redd.it/oxk7fj852oq41.jpg?width=1400&format=pjpg&auto=webp&s=aa6b7dfa017cdaf621c653be747a7c7630f46639
This timeline shows the Bitcoin Cash split from Bitcoin was on August 1, 2017, the Bitcoin SV split from Bitcoin Cash on November 15, 2018, and Bitcoin SC will split from Bitcoin in the June timeframe at a block height TBD.

Next, consideration of some of the technical issues for these hard forks.

Block Size


Block size is an important parameter in blockchain configuration since it controls scaling for transaction capacity, transactions per second, and node requirements. Block size has been a contentious issue in the blockchain community and has been a motivating factor for past chain splits.

Table 1 - Block Size

Bitcoin launched with a 1.0 MB block size, and has retained this size although adjustments using block “weight” for SegWit transactions allow larger blocks. Bitcoin Cash launched with an initial block size of 8 MB, and hard forked in May 2018 to a size of 32 MB.

Bitcoin SV features very large blocks, launched with 128 MB, and implemented the Quasar protocol in July 2019 allowing blocks up to 2 GB.

Bitcoin SC will launch with 2.0 MB blocks and is scalable up to 32 MB size (plus the SegWit “weight” adjustment).

Another way to examine block size and TPS is to see actual usage of blocks on-chain. Blockchains are occasionally overloaded, but most run at a lesser capacity than full blocks.

getchaintxstats give some statistics for the blockchain capacity usage over the past 4,320 blocks or 30 days. Table 2 gives transactions during the last 30 days (window_tx_count) and TPS (txrate) and shows an actual usage rate over the last month of 3.4 TPS for Bitcoin, 0.5 TPS for Bitcoin Cash and 6.3 TPS for Bitcoin SV.


Table 2 - getchainxstats

The commonly used value for Bitcoin TPS is 4, implying a transaction size of 417 bytes, and using SegWit transactions would give higher throughput. Bitcoin SC with 2 MB block size would give 2x Bitcoin TPS.

Block Height Delta

As you know, difficulty is adjusted every 2,016 blocks (~ 2 weeks) to maintain the 10-minute block spacing. In a perfect world, after splitting from the Bitcoin blockchain, the split chains would run block height roughly in sync with Bitcoin block height. However, various tweaks attempting to improve difficulty adjustment can decouple block height on the split chains.

By definition, at the hard fork block height, the main chain and split chain are exactly in sync. There are minimal practical issues with these different block heights, although it is nice when software does what you are expecting for block spacing. Perhaps the only implication for different block heights is that halvings will occur at different times, so more for reference, the approximate block height offsets are shown below.


Table 3 - Block Height Offset

Again, the practical implication of these block height offsets is that Bitcoin Cash and Bitcoin SV will reach their halvings a little over a month earlier than Bitcoin.

Bitcoin SC may use a more frequent and gentler difficulty adjustment algo, effectively tracking closer to the Bitcoin block height.

Replay Attacks


Since the addresses, private keys and coins are otherwise identical between Bitcoin and a forked chain, developers of the new split chain can add replay protection. Without replay protection, a signed transaction from one chain will validate and execute on the split chain in a “replay attack”, as Ethereum discovered in 2016.

Bitcoin Cash added replay protection in their hard fork by adding a marker so that signatures wouldn’t match between Bitcoin and Bitcoin Cash (two-way replay protection). Bitcoin SV did not initially add replay protection (for philosophical reasons). Bitcoin SC will add replay protection using a modified signature similar to Bitcoin Cash.

Opcodes and Bytecodes


Bitcoin and its forks use script opcodes for basic programming operations executed on a stack. By design, script has limited capability for safety and of the ~100 opcodes available, relatively few are used for normal transactions (pay2pubkeyhash, multi-sig, etc.).

Table 4 - Opcodes

There is a slight variation in opcodes between these projects. Table 4 shows the count in current release GetOpName() function. The Bitcoin SV count includes 16 opcodes (OP_1 — OP16) for pushing onto the stack but otherwise is in the same size range as Bitcoin and Bitcoin Cash.

Bitcoin SC, forked from Bitcoin v0.19, will include additional opcodes for interfacing with the smart contract layer, which will offer Turing-complete on-chain smart contract execution with ~100 bytecodes (e.g., a Constantinople-class virtual machine). In contrast to Bitcoin and these other forks, Bitcoin SC is a fully programmable blockchain, capable of running on-chain applications such as decentralized exchanges and DeFi solutions.

The future of cryptocurrencies from from the perspective of privacy and anonymity

The future of cryptocurrencies from from the perspective of privacy and anonymity
Cryptocurrency, also known as digital currency and virtual currency, is a kind of monetary system represented by BTC, which is based on public account technology. *
According to coinmarketcap, there are 2,473 cryptocurrencies and more than 400 exchanges in the world. The global market value is about $260 billion.

https://preview.redd.it/pln7ame1rii31.png?width=601&format=png&auto=webp&s=e1b365980768fe53655d5c6e56b42ad4677c35d8
In 2019, the cryptocurrency field showed its strong vitality. It has been more than 11 years since Satoshi Nakamoto published the whitepaper of bitcoin in 2008, and the blockchain technology has derived tokenize, STO (Security Token Offering), IOT (Internet of things), product traceability, financial derivatives (share option, future goods, prompt goods) and other industrial applications from the initial peer-to-peer electronic cash.
This paper focuses on the anonymity of cryptocurrency, so it divides cryptocurrency into 'non-anonymous cryptocurrency' and 'anonymous cryptocurrency' to discuss and research.
The merits and demerits of non-anonymous cryptocurrency
First of all, we have to admit that the non-anonymous currency does not mean the real name and all the non-anonymous currencies have a certain degree of anonymity, which is embodied with its address (it can be regarded as the bank card number) that consists of dozens of letters and numbers. The blockchain browser allows us to track the past transaction records and the amount of coin held in each address.

https://preview.redd.it/6h2j7ij2rii31.png?width=677&format=png&auto=webp&s=b03355c3330bf544d087100081029ddb4a2d4f7e
[The bitcoin blockchain browser data, from blockchaininfo]
The above is the partial transaction packaged by bitcoin block height #591204 on 7: 49, 22 August, 2019, New York time. We can clearly see the both parties’ addresses, transaction amount and gas fee. If you click any address, you can check any past transactions of this address.
Open and transparent account has its scientific basis, which has the following advantages: reducing the cost of trust; collective maintenance to reduce the centralized risk; reliable database and its source is always available and traceable.
But behind value shaping is the price that must be paid.
We can assume that if an address sends a transaction for illegal purposes, and the address is put on the watchlist of the law enforcement, does it mean that all transactions passing through this addresses will be affected? If I receive these bitcoins through normal transactions without knowing it, does it mean that I, as an ordinary person, will be forced to get involved?
Secondly, every time we send a transaction, my balance is known to others. If I hold a large amount of bitcoin and both parties know each other's identity, who will guarantee my personal safety? Some people have proposed the decentralized management of bitcoin. Have you ever thought about the cost of secure storage of decentralized management? And with the technology development, in the future, the big data technology will not be difficult to crack the holders by behavior analysis and address transaction trajectory analysis.
Anonymous cryptocurrency is coming
In April 2014, monero(XMR)* was officially launched, focusing on privacy, decentralization and scalability. Unlike many cryptocurrencies derived from bitcoin, Monero is based on the CryptoNote protocol and has significant algorithm differences in block chain fuzzification.
On 10 January, 2017, by using the Ring Confidential Transactions algorithm of Gregory Maxwell, a Bitcoin Core developer, the privacy of monero transactions was further enhanced from #1220516 block. The ring signature algorithm does not reveal the amount involved in a transaction to people who are not directly involved in the transaction, thus increasing the confidentiality.
The above is monero memorabilia on privacy protection. There are three aspects of its privacy: privacy
ring signature - sender, untraceable
aliasing address - receiver, unlinkable
ring confidentiality - hiding transaction amount
Monroe is at the top of improving privacy and anonymity. It perfectly solves the privacy problem of the bitcoin network. We can understand that each transaction you receive or send can be effectively confirmed by only you and your counterparty.

[The monero blockchain browser, from moneroblocksinfo]
So menlo became a hotbed of illicit trade and the target of public criticism --
On 18 March, 2018, Coincheck said it would remove three anonymous cryptocurrencies: XMR, DASH and ZEC. Many other exchanges in Korea and Japan also removed such cryptocurrencies with untraceable and anonymous transmission and transaction ability such as XMR, ZEC, DASH and so on, which is speculated to be related to the requirements of government regulators.
To find a balance between anonymity and non-anonymity
In July 2019, cryptozoic(VCC)* was born. Its original ‘aliasing anonymous mechanism’ and ability compatible with ‘semi-anonymous digital currency’of ETH (Ethereum) have been making waves in the digital currency industry.
According to the Cryptozoic(VCC) whitepaper, cryptozoic is a DApp operating environment compatible with ethereum. In addition, it has distributed anonymous computing systems beyond BTC and ETH. The anonymous blockchain system adopts UTXO model +DAG and virtual machine program to write and execute smart contract.
Anonymity + Public Verifiability

https://preview.redd.it/d6vt54p4rii31.png?width=655&format=png&auto=webp&s=dfd30886eff499c16a220ce8a1bb7dec7ebe643f
[The VCC blockchain browser, from vccscancom]
As can be seen from the figure above, in the blockchain transaction of VCC network, the sender's address is hidden and the receiver's address is displayed. We can still check the balance data by clicking the receiver's address. But for the transaction record, outsiders cannot access accurate data except for the owner of the address. In this way, VCC has a place between absolute anonymity and absolute transparency: public verification + law enforcement review. At this point, VCC has taken a unique step forward.
High Concurrency + High Scalability
Pure POW mining coins like bitcoin, are limited by the block time and block size, so their TPS are very limited, which can handle only seven transactions per second on average. In 2017, CryptoKitties, a popular blockchain game based on ethereum, was jammed for hours due to the huge number of participants. VCC, combined with the mining advantages of DPOS+POW, maintains the transaction rate with DPOS super node on the premise of ensuring the fairness of POW, which theoretically can reach 80,000 transactions per second and perfectly solves the problem of transaction congestion.
VCC adopts directed acyclic graph (DAG) *, which is a promising new approach to scalability problems and is considered considered as the solution of machine-to-machine economy(M2M).

https://preview.redd.it/a7rn9si5rii31.png?width=661&format=png&auto=webp&s=672639aeff6923500300e71a6865a8c4d5db2c10
[DAG diagram]
DAG allows multiple blockchains to coexist and to connect to each other without an edge with the parent node. Nodes can exist in parallel as long as information is directed in the same way. It opens a whole new set of possible confirmation options to eliminate the need for block time and reduce the amount of work wasted on abandoned [isolated chain]. The final result is that: there is huge potential for highly scalability and fast information flows on the completely decentralized network.
Conclusion: the absolute transparency may hurt the innocent, while the absolute anonymous protection becomes the hotbed of illegal industry. Perhaps the future of cryptocurrencies can be found in VCC (Crypotozoic), which is a fabulous non-absolute anonymous and highly scalable digital currency.

Lightning Bitcoin: The DPoS based Forked Bitcoin

Lightning Bitcoin: The DPoS based Forked Bitcoin
Cryptocurrency has been a global phenomenon. However, there is an inherent issue with the concept. The slower functionality and higher transaction charges are the two concerns being addressed with the aid of Lightning Bitcoin which forked on December 18, 2017. The Forked crypto coin is set to launch Smart Contracts and Zero Knowledge Proof in 2019.

Lightning Bitcoin – A Complete hard fork of Bitcoin blockchain

The Lightning Bitcoin is the unique coin that adopts DPoS Consensus mechanism. The technology aims at improving the concept of bitcoin and solving the problems associated with centralization of miners and network congestion you would have observed in Bitcoin Blockchain.
Lightning Bitcoin itself should be indicative of the fast transaction speed as compared to the regular Bitcoin features. As Dan Larimer, the creator of DPoS consensus mechanism claims “This design was chosen to ensure that delegates technically have no direct power and that all changes to the network parameters are ultimately approved by the stakeholders”.

https://preview.redd.it/f3giwubnwyi11.jpg?width=3496&format=pjpg&auto=webp&s=4dfa79dce8686205ff4a2413c01bdf6d18d969c6
What makes LBTC a unique project is the DPoS Consensus Mechanism it adopts. It reduces the negative effects algorithm from PoW consensus mechanism, which is congestion and centralization. In fact, it offers a better solution for network decentralization, which leverages the power of stakeholder approval voting to resolve consensus issues democratically. This can go a long way in enhancing the profits for the coin holders – whether promoters or investors and the complete efficiency of the network. The DPoS consensus lets the network get an improved transaction speed as a result of the enhanced consensus speed.
In fact, DPoS gives a specific schedule for the addition of next block to the blockchain. Thus you would not need specialized computers for solving mathematical algorithms in sharp contrast to PoW. Moreover, it reduces the chances of centralisation, unlike PoW where anyone with huge mining capacity has the options to form centralized mechanism. DPoS lets the coin holders choose who can validate the transactions. This improves the transaction performance and a high degree of decentralization.
The Lightning Bitcoin forked at the Bitcoin block height 499,999 on December 18th, 2017. The mainnet launched in February 2018. Currently, Lightning Bitcoin is actively developing core technology part and expanding its presence on cryptocurrency exchanges. LBTC has already been listed on six exchanges like CoinEgg, BTCTrade and supported by Cobo and Bitpie mobile wallets. Future development steps imply addition of creating smart contracts and DApps on the Lightning Bitcoin networks that would allow an alternative solution for the cross-chain atomic transaction.

What’s unique about Lightning Bitcoin’s DPoS

DPoS Consensus is what makes LBTC stand out from the rest of the Bitcoin forks. What exactly is DPoS and how does it benefit Lightning Bitcoin? Well, DPoS refers to the Delegated Proof of Stake. It offers the power of voting to the token holders to delegate the right of bookkeeping to trusted nodes and thus works along the lines of true democracy.
What we mean by democracy is the fact that it completely decentralizes the entire bitcoin network. There is no central power that controls the miners or the functioning of the network. However, the dynamic structure of 101 trusted delegates that keep turns in forging blocks. To borrow the words of LTBC itself, “DPOS consensus significantly reduces the number of participating verification nodes, 101 nodes in case of LBTC, and help LBTC reach consensus in seconds and boost the transaction speed to be as fast as lighting really”. LBTC works with instant transaction verification mechanism. The transactions are verified within block forging time, which is 3 seconds. This instant verification is excellent for a swapping vast and small amount of coins with low transaction costs.

The Future Ahead

The LBTC network is still under development. It is quite easy to get into the delegates board right away. If you want to be one of the delegates, you just need to meet the technical requirements, pay your registration fees and get a sufficient number of votes to qualify for the top 101 list – no need for coin lock up or network checks of any kind.
To prevent the network centralization by the delegate pool, there will be an integration of delegate committee system and lightning nodes elections. This will set requirements on coins lock up like it is in EOS or Vechain, delegates will have to provide information about their profiles thus turning the voting process into clear transparent mechanism based on delegate weight in the community.
In any case, we would look at Lightning Bitcoin as an attempt at an enhanced network with the all-powerful and democratically correct DPoS Consensus that makes the forked Bitcoin service one of the excellent alternatives to the host of Bitcoin clones you may come across while looking to invest in the cryptocurrency arena. From that perspective, it is indeed something we will have a close look at. Of course, there is no whitepaper available as yet, but we would indeed foresee a great future for the most democratic version of the cryptocurrency and a forked Bitcoin network that would indeed offer the best investment options.

Looking for more development help

A big thing from the meeting today that became apparent is that we need more development help before we can plan a timeline for Bitcoin Private.
The first steps are:
  1. Appending the Bitcoin UTXO set as coinbase inputs on top of the Zclassic blockchain for any Bitcoin block height
  2. Implementing Zclassic replay protection
  3. Setting up a testnet.

BTN strategic cooperation with QTUM

On January 9, the New Bitcoin Foundation (BTN) announced that it has entered into a strategic cooperation with Qtum, a world-renowned blockchain platform, and both sides will conduct in-depth discussions on cryptography, smart contracts and consensus mechanisms in the blockchain Exchange, future or together to create a blockchain ecosystem.
 
Based on their mutual recognition, the Foundation has decided to replace 1% of Qtum with a BTN of 2% of the total, and the market capitalization of BTN with a birth rate of just over two weeks exceeds $ 2.5 billion. In addition, Qtum founder and CEO Patrick Dai will serve as Chief Advisor to the New Bitcoin (BTN) Foundation.
 
New Bitcoin (BTN) is a digital token dominated by the BTN Foundation and bifurcated at Bitcoin block height 501000 at 2:26 am on December 26, 2017, Beijing time. BTN Foundation upholds the principles of fair game, shared spirit, open source ecology and decentralization, and is committed to building one of the world's largest distributed application platforms.
 
Qtum was officially launched in March 2017 and is now traded on exchanges. As the first smart contract platform based on evidence of equity, the Qtum is widely recognized for its security, scalability, and business friendliness, with nearly 3 million community users worldwide and nearly 250 developers.
 
Zhang Yu, secretary general of BTN Foundation, said the cooperation shows the mutual recognition and affirmation of both sides. In the meantime, Zhang Yu also revealed that the new Bitcoin (BTN) has recently completed a series of tasks ranging from the construction of the mine pool to the commissioning of wallets. The digging procedure has also been opened to the outside world. The online exchange is proceeding in an orderly manner. Announce specific issues.
 
Qtum also expressed optimism about this cooperation. Qtum co founder and CEO Patrick Dai said the blockchain concept and platform design of the New Bitcoin (BTN) Foundation is impressive. Qtum has rich experience in blockchain technology and numerous project experiences. Help new bitcoin (BTN) better and faster development.
 
Recently, the 360 ​​Financial Blockchain Research Center, Qtum and the New Bitcoin (BTN) Foundation jointly announced the depth of cooperation in the underlying technology blockchain, the establishment of the bottom of the blockchain technology laboratory to promote the district Block chain technology research and development.
 
The key is that the 360 ​​Financial Blockchain Research Center, the Qtum and the BTN Foundation complement each other and will collaborate in various fields:

Guidelines for Bitcoin Holders Wanting to Claim Bitcoin Parallel and Bitcoin Parallel Clearing

According to the rules of the Bitcoin Parallel Foundation, Bitcoin Parallel (BCP) and Bitcoin Parallel Clearing (BCPC) are available to a Bitcoin (BTC) holder only if he has an address of not less than 0.01 BTC at a Bitcoin block height of 507,000 (Bitcoin Block Snapshot). The number of BCPs and BCPCs being claimed is not related to the change in the number of BTCs in the BTC address after taking the snapshot. If your Bitcoin is on an exchange, it is not possible to claim BCP and BCPC using the Bitcoin address because your Bitcoin is not at your recharge address, but is rather in an exchange-controlled wallet. You can contact your exchange and ask them to unify the BCP and BCPC and then allocate portions to each holder based on the percentage of the BTC he owns at the time of the snapshot block. For BTC holders in exchanges that do not allow them to claim BCP and BCPC, the Bitcoin Parallel Foundation is exploring new ways of making claims that would solve this problem. The foundation will announce any new policies on their website. Please keep an eye on it for announcements. If your BTC is kept in a wallet that can independently transfer Bitcoin from a specified address, you can visit the website to make a claim. Since the recently popular multi-address Bitcoin hardware and software wallets (e.g., Blockchain.info, Trezor, Ledger) can have more than one address, they usually cannot be used to transfer Bitcoin (there is no way to specify which address you want used). There are two problems that many users encounter when trying to claim BCP and BCPC using the Bitcoin Parallel Official application process: (1) not knowing the specific address of the BTC in their wallets; and (2) not being able to control their wallets in a way that allows them to transfer a specific amount from a specific address. In response to this situation, we provide our users with the following guidelines for reference: (1) Determine which addresses in your wallet are eligible for BCP and BCPC. You may do this (1) by using the Bitcoin browsing tools and (2) by analyzing the wallet transaction records. (3) You can also enter the wallet address in the application, at which time you will be asked to fill in the Bitcoin address. After a query of the website’s backstage data, you will be told whether the address is valid for claiming BCP and BCPC. (2) Make one claim at a time using valid Bitcoin addresses. Since Bitcoin wallets do not have the ability to specify from which address Bitcoin will be transferred, it is recommended that the wallet user transfer all Bitcoin balances (including the decimals) to an address that is valid for making claims from. Then use the wallet to transfer Bitcoin corresponding to the “random amount” to any address. This time, since Bitcoin is only present at the claiming address, it can only be transferred from that address. So the verification steps will work. This operation can be repeated for each address that meets the criteria. Please note that the amount of Bitcoin used in the verification is the amount at the time of the snapshot, not the amount at the time of the application (should they be different).

A math problem to help people understand the bitcoin blockchain.

I have a very mathematically orientated friend that I was trying to explain the blockchain to and decided to write it as a maths problem. He seemed to understand the concept almost instantly after looking at this.
f(x0,y0,z0)=x1 where x1 The function is a digest algorithm (irreversible). x0 is given diff0 through n is given. y is random number (transaction data) which is given. z is to be found.
I was surprised at how simple this turned out, and from there I was able to explain how difficulty is set, 51% attacks, the decentralized nature of bitcoin, block height, size and propagation problems.
I thought it might help some others.
Edit: typos
