BIP91 vs August 1st

BIP91 reaches 80.5% network support
19 July 2017   3771

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

Bitcoin community has lost sleep for a couple of months over SegWit2x and the Bitcoin User Activated Soft Fork (UASF) which is to be activated on August the 1st.

Now, while a significant part of users is concerned about a possible hardfork in the Bitcoin network, the miners begin to vote for BIP91 proposal as it is considered to have good chances to become an unexpected compromise solution in the debate on consensus.

In fact, it is the only proposal actively preventing a Bitcoin chain split right now. The bigger question is whether or not BIP91 can gain enough traction in the coming days.

The support for BIP91 is certainly on the rise. Various mining pools are actively signaling support for this solution right now: 80.5% of blocks mined over the past 24 hours support this solution. It goes without saying that scaling Bitcoin without a chain split should be in everybody’s best interest.

Why BIP91?

The implementation of softfork in the Bitcoin network requires miners to include a special signal bit into the blocks, thereby showing their willingness to adopt the new rules. The original version of Segwit2x required the inclusion of the fourth signal bit (bit 4) in order to support BIP141, and that's when the conflict appeared, because the BIP141 code had been already written to respond to the first signal bit (bit 1).

To bypass this conflict, BIP91 uses an additional bit signaling the mandatory acceptance of the original first signal bit. Accordingly, there is no need to change the already existing SegWit activation logic.

Thus, if BIP91 to be activated before July 31th, it will replace BIP148, which also assumes the activation of SegWit, but carries the risk of splitting the Bitcoin network into several blockchains.

However, if one big mining pool stops signaling it, BIP91 will be back below 80% pretty quickly. Given that some pools like to play games with the rest of the Bitcoin community, BIP91 may never happen in the end. After all, there are less than two weeks to see it get locked in, which means time is of the essence.

CB is a series of premium Blockchain events that connect ICO companies with the brightest industry minds and the latest in technological innovation. CB is the place where the future of Blockchain Industry is unboxed and brought to life. And when you consider this study by U.K. research firm Juniper Research, more than half of the world’s large corporations are looking into blockchain (distributed ledger technology), then it’s a high time you consider the blockchain technology. The research highlights that 57 percent of large corporations- defined as any company with more than 20,000 employees- were either actively considering or in the process of deploying blockchain. And two-thirds of companies surveyed said that they expected the technology to be integrated into their systems by the end of 2018.

It is clear that companies across the board have a significantly greater understanding of blockchain technology than was the case 12 months ago. This stems in part from a surge in R&D (research and development) both internally and in partnership with third parties, with a recognition that blockchain has the potential to be deployed in a variety of use cases.
As the number of research projects has increased, so too has awareness, both amongst the participants and elsewhere in their industries, with competitor companies in turn beginning to consider whether they too should seek to gain competitive advantage from deployment.
