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, 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.

Bitcoin can be sent via SMS

A new app that is meant to oppose Internet censorship is announced

A group of developers of a bitcoin-wallet Samourai, prioritizing privacy above all, has announced a unique app Pony Direct. It allows sending transactions to the Bitcoin network through SMS.

In a modern world, blocking access to the Internet based on a plethora of reasons becomes a censorship tool. In order to ensure a continuous flow of transactions, a solution that uses SMS to bypass such restrictions was realized. Considering the nature of an SMS to have a limit on symbols, a datachain of a transaction is first divided into corresponding parts to fit into multiple SMSs, the messages get sent and the receiving device that has a direct access to the Internet extracts the data from the SMSs and re-assembles the chain. Then, the recovered datachain is pushed into the Bitcoin network.

The idea of using SMS is not brand new: in summer of 2017 a Czech developer Pavol Prusnak created a tiny software that allowed transacting by means of SMS. The real difference of the announced product is that it is a full fledged bitcoin-wallet. The first readers of the announcement have warmly welcomed the project.

Lastly, following the team’s spirit of open source, everyone is free to check the app out by accessing the Github project page directly.
