Segwit2x working group unveils hard fork plan

Segwit2x working group has announced hard fork roadmap
10 August 2017   1006

Segregated Witness is the process by which the block size limit on a blockchain is increased by removing signature data from Bitcoin transactions. When certain parts of a transaction are removed, this frees up space or capacity to add more transactions to the chain. 

Now, SegWit has locked-in and the Segwit2x working group has announced its roadmap for the next several months. The team of developers have detailed they are going forward with the 2MB block size increase that miners and businesses agreed upon at the New York Agreement.

During the month of November 2017, approximately 90 days after the activation of Segregated Witnesses in the Bitcoin blockchain, a block between 1MB and 2MB in size will be generated by Bitcoin miners in a move to increase network capacity. At this point it is expected that more than 90% of the computational capacity that secures the Bitcoin network will carry on mining on top of this large block.

According to the announcement, the upgrade to 2MB blocks has been agreed first during the Bitcoin Roundtable Consensus in Hong-Kong on February 2016, and then ratified by the Bitcoin Scaling Agreement in New York on May 2017. These agreements stipulate the activation of Segregated Witness support and an increase of the maximum block size from 1MB to 2MB.

As the working group claims, now that Segwit has locked-in, the ecosystem should update to Segwit-compatible software if they want to benefit from the protocol. The announcement also explains “readiness” preparation for the fork including port changes, network changes, DNS seeds, and the Segwit2x “Testnet5.”  

The November 2017 upgrade to 2MB blocks is a hard-fork, but necessary changes are trivial to perform. Some SPV clients are expected to work without any change at all. Most clients will need to tweak only two constants to remain compatible with the new larger blocks.

The Segwit2x hard fork is to take place on the block 494,784, while the client will be incompatible with the current version of Bitcoin Core and the software of the node holders that support UASF.

It's worth mentioning that the Segwit2x proposal continues to be criticized by a significant part of the community. The main reason is that it was accepted behind closed doors without broad discussions. In addition, there is already a blockchain with larger blocks (Bitcoin Cash) and the original chain, having successfully survived one shock, hardly needs another one.

CB is a series of premium Blockchain events that connect ICO companies with the brightest industry minds and the latest in technological innovation. CB is the place where the future of Blockchain Industry is unboxed and brought to life. And when you consider this study by U.K. research firm Juniper Research, more than half of the world’s large corporations are looking into blockchain (distributed ledger technology), then it’s a high time you consider the blockchain technology. The research highlights that 57 percent of large corporations- defined as any company with more than 20,000 employees- were either actively considering or in the process of deploying blockchain. And two-thirds of companies surveyed said that they expected the technology to be integrated into their systems by the end of 2018.

It is clear that companies across the board have a significantly greater understanding of blockchain technology than was the case 12 months ago. This stems in part from a surge in R&D (research and development) both internally and in partnership with third parties, with a recognition that blockchain has the potential to be deployed in a variety of use cases.
As the number of research projects has increased, so too has awareness, both amongst the participants and elsewhere in their industries, with competitor companies in turn beginning to consider whether they too should seek to gain competitive advantage from deployment.
