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, 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?

Twitter CEO: BTC to be Single Currency in Decade

Jack Dorsey has a strong belief in the future potential of bitcoin

CEO Twitter Jack Dorsey believes that after 10 years bitcoin will bypass the importance of the US dollar and become the most relevant currency in the world, which will be used by billions of users around the world. The businessman said this in a commentary to the British edition of The Times.

The world ultimately will have a single currency, the internet will have a single currency. I personally believe that it will be bitcoin.As more and more people have it, those things go away. There are newer technologies that build off of blockchain and make it more approachable.

Jack Dorsey

CEO, Twitter

Despite the fact that at the moment the bitcoin continues to experience certain problems that, according to Dorsey, prevent him from becoming an "effective currency," further development of the protocol, he believes, will inevitably lead to necessary changes.

The last thought of Jack Dorsey, who is also the founder of the payment start-up Square, seems to refer to the Lightning Network technology - the second layer of bitcoin scaling, which allows for instant and exceptionally cheap microtransactions.
