Is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen.

Today's morning, July 23, the activation BIP 91 started. Now all the blocks that do not signal support of Segregated Witness (SegWit), will be rejected.

According to xbt.eu, 97.9% of the miners support SegWit.

BIP 91 is a modified version of the BTC1 (SegWit2x), which supported a number of bitcoin-companies and mining pools, in May of 2017 signed under the relevant agreement in New York. In addition, BIP 91 is compatible with BIP 148 (UASF) - another proposal to activate the original SegWit offer, described in BIP 141.

Distributed database that is used to maintain a continuously growing list of records, called blocks.

Thus, the activation of BIP 91 also means a high probability of activation of the BTC1 protocol (SegWit2x) and the actual elimination of the risk of bitcoin hardfork due to the activation of BIP 148, which should occur on August 1.

At the same time, there is still a probability of a hardfork as a result of the increase in the block size to 2 MB, provided by SegWit2x within three months after the activation of SegWit.

BIP 91 was activated on block 477120. The next update of the level of complexity should take place on block 477792, therefore, if nothing unforeseen happens, SegWit should be fixed on 479808 (mid-August), and the direct activation of the protocol on block 481824 (end of August).

And what about Bitcoin price?

Bitcoin lost 3.15% of his price in 24 hours and now is $2729.38. Is it just a little "fall" or a harbinger of a precipitous collapse? Or Bitcoin will rise rapidly? We will see. 

On the 27th of July, another Bitcoin optimization protocol signaling stage have started - BIP141.

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.
