Bitcoin infighting did not end with the BCH fork two months ago. The saga over the future of the network and payment scaling proceeds with the SegWit2X fork dawning on the community. Some would argue that this fork is not relevant, since SegWit was already activated and a fresh cryptocurrency with thicker blocks but no SegWit already hit the market. The SegWit2X agreement was designed – at least in part – to prevent the split that brought BCH into the market. Therefore, logically at least, there shouldn’t be a reason to deploy a SegWit2X hard fork, but then again, SegWit is supposed to be a malleability fix and not a scaling one.
Spare me the Technical Details About SegWit2X Fork and Let’s Talk Economics!
This is exactly the point at which the debate starts getting technical. We will leave all the technical aspects of the SegWit2X fork to those who specialize in technical issues. There are a few critical implications about the fork itself that are crucial on the economic side. This is the side of the SegWit2X fork that we will concentrate on and these are the implications that could affect it:
- The fork might bring the risk of replay attacks, in which valid transactions can be fraudulently repeated.
- Confusion about which is the “real” bitcoin – both versions of the coin could stake a claim to the bitcoin name. Exchanges that support 2X could claim that this is in effect bitcoin, and stir users arbitrarily onto a version of bitcoin – or a fresh coin – that users don’t necessarily agree with.
- There is a possibility that addresses on both chains will be similar, creating confusion and lost coins on transactions of coins on one chain to addresses on the other.
SegWit2X Fork: Incentives
The economics of the SegWit2X fork become more complicated when considering the incentives of the miners, companies and users. As of now, an tremendous majority of miners support 2X. Around 94% of the last 1,000 blocks mined support the 2X proposal. Bitcoin.org, however, has reminded all of us once again that miners do not “rule” the network. The concentrate then goes onto knots – users – but there is still a risk that many other economic actors apart from miners will support SegWit2X. If the companies that signed the NYA stay the course and support the SegWit2X fork, users who do not support the fork could be compelled into a corner.
Is the SegWit2X fork debate about to warmth up? Could this fork be even more contentious than the BCH fork?
This makes the post fork situation a complicated one. The market will ultimately determine which is the real bitcoin by virtue of usage and acceptance, but this might not be as clear cut as it was with the BCH fork. While some signatories of the NYA have since withdrawn their support, there is still a substantial number of economic actors that can become market makers, supporting 2X. It will all come down to the incentives, but in the meantime, bitcoin prices can suffer.
SegWit2X Fork Readiness Similar to Prep for UASF
It is therefore prudent for users to prepare themselves for the fork just like they did for the August 1 st UASF. Users need to take control over their private keys ahead of the possible split. This fork might not become a ‘dividend’ like the last one, so it is significant for each user to determine how much risk they are willing to take. Following the fork, prices might be affected and transactions could be slowed down if a significant part of the miners budge onto SegWit2X – 94% of them are supporting it already – prompted by the proclaimed support from all the potential market makers.
The Solution That Became a Problem
Evidently, despite the BCH fork it is clear that bitcoin is not out of the forest yet. All those Twitter users who were gladfully proclaiming that August 1 st would be Independence Day failed to take the SegWit2X fork into account. The Silbert Agreement – NYA – did not go away and now it is suspending over the network. This compromise designed to prevent the very first split and provide an alternative to the turmoil is now bitcoin’s main source of endogenous instability. It seems that SegWit2X is the solution that became a problem, and regardless of its objective relevance, it could end up pulling bitcoin prices down. Hopefully as the late November fork deadline approaches, the picture will become clearer.
