Bitcoin Software Wars: The Case Against Replay Attack Protection

The Question Remains — Who Should Add Replay Attack Protection?

Jeff Garzik: ‘A Whole Lot of For Thee, But Not For Me Going On’
Now that Opt-in replay has been added to the Segwit2x fork, many bitcoin proponents now believe if Core developers really want a better safeguard — they should be the team to deploy one. Two weeks ago Segwit2x lead developer Jeff Garzik asked bitcoin proponents why Core hasn’t contemplated adding any replay protections. “Any idea when bitcoin Core will add replay protection? There’s a whole lot of ‘For Thee, But Not For Me’ going on,” Garzik asks his Twitter followers. In another conversation over Twitter with Dmitry “Rassah” Murashchik and Blockstream CEO Adam Back, the former Mycelium employee asks Back, “Are you worried that the other chain would win? That’s really the only reason for replay protection.” This is after Back tells his followers that the lack of Segwit2x’s replay protection is “inexcusable.”Daniel Krawisz: ‘You Can’t Win With That Attitude’

Krawisz’s opinion reflects his past statements about hard forks and his thoughts about the Bitcoin Cash network and how investors are “Gods” who choose the best protocol in the end. “To me, the bitcoin developers are like the Dynasty and investors are like the mandate from heaven,” Krawisz details. “Sometimes the Dynasty becomes corrupt, and there needs to be new blood, and a new family takes over the empire — Then they have the mandate from heaven. That’s what the investors do, so if bitcoin forks they choose which one wins.”You need to be saying, “ No I am the ‘true bitcoin’ I’m going to defeat you — You should implement replay attack protection against me.” Yeah, that’s how it should work.

A Fork of a Different Color
With a significant amount of business support and a majority of the hashrate, the Segwit2x developers believe the fork will be the ‘true’ bitcoin. As Jeff Garzik stated in the past on the BTC1 Github repo, “The goal of Segwit2x is to upgrade Bitcoin — to be Bitcoin — not create an altcoin.” Whether this happens or not is a different story, and cryptocurrency enthusiasts will watch another historic moment in bitcoin history as this fork will likely be rather different than the one on August 1. What do you think about the hard fork that’s approaching this November? Do you think we will see another network split?
