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.
However, another company withdraws its support for SegWit2x leaving NYA Bitcoin agreement. Thus, Bitcoin peer-to-peer lending platform Wayniloans made the announcement indicating a change in their minds. Wayniloans co-founder Juan Salviolo claims that, when they signed the NYA, they did not realize how contentious the scaling proposal would be. Specifically, they cited concerns that Core developers universally oppose it and that it is unpopular in Latin America.
On Wayniloans part or our business is achieved thanks to Bitcoin, and on May we agreed to a sentence to reach consensus for the good of the ecosystem….At the time we didn’t know that existing developers wouldn’t support it, or that most Latin American Bitcoin users, our customers, would view it as an contentious proposal. <...> Also, without mandatory replay protection (not opt-in) on SegWit2x, we wouldn’t be able to operate the crypto part of our business without risk of missing funds or legal actions.
Wayniloans criticizes NYA proponents for not implementing mandatory, opt-out replay protection, which would prevent attackers from broadcasting transactions on both blockchains and stealing coins from unwitting victims.
