Yet another cryptocurrency exchange leaves SegWit2x agreement.

This time this is the Latin American Bitcoin exchange, SurBTC, refused to support SegWit2x just a month before the planned November hardfork. 

The company claims that the new hardfork could be unsafe and is not supported by the Bitcoin Core developers. Indeed, Bitcoin.org has just published a “blacklist” of websites that continue to support the SegWit2x hardfork, arguing that storing any BTC on such services is strongly not recommended. 

We’ve always loved SegWit and we see a small increment (2mb) in the size of the block as a good idea as it would relieve pressure, lower fees and give some time to other more definitive scaling alternatives such as the Lightning Network to develop. Nevertheless, we can’t pretend to be bitcoin “scaling experts”. We don’t believe in trying to force a change bitcoin’s core developers don’t feel safe with.

The company also highlights that they haven’t seen proper support and they "don’t like what they currently see on the btc1 code repository in terms of technical considerations and open source collaboration".

SurBTC argues to be defending the interests of a growing Latin American user community that feels strongly against a new contentious hardfork. Thus, if the hardfork does happen, the exchange could eventually list both assets but will allow for sure its users to at least withdraw both. Due to practical reasons, SurBTC will continue to list BTC, and they will incorporate B2X (or the names that catch on among the industry) later.

Samourai Wallet: SegWit2x is an attack on the network

Another Bitcoin-related company expressed its position regrading upcoming SegWit2x
18 October

Samourai Wallet team said that the SegWit2x is a controversial and unnecessary change in the current rules of the network and it is the attempt of a small group of players to take control over the development of the open code of bitcoin. This is stated in the official blog of the company.

As noted in the statement, Samourai Wallet supports the development of open source code by the Bitcoin Core team, which, according to company representatives, timely introduces all the necessary updates. In this regard, the service will support the longest chain of blocks, compatible with Bitcoin Core 0.15 nodes.

The S2X hard fork is particularly troubling as the development team have NOT added an important safeguard known as ‘replay protection’ to their software. Without replay protection any transaction sent on either of the chains may also be sent on the other chain (‘replayed’), leading to the high potential of users losing funds. Because of the willful insistence by the developer(s) to not add replay protection, we are classifying this hard fork as an attack on the network.

In this regard, the service will offer additional measures to protect against repetitive playback in the case of hard-core.

It is also stressed that Samourai Wallet will not provide users with access to the equivalent number of S2X tokens, and will offer to convert them to BTC at the market price.
