Today marks the unloose of Bitcoin Core version 0.13.1. This is the official introduction of Segregated Witness, the long-awaited centerpiece of Bitcoin Core’s scalability route map. Starting Nov 15, Bitcoin miners tin signal back upward for the proposed protocol upgrade, which, if activated, enables a number of novel features on the Bitcoin network every bit good every bit an effective block size bound increase.
According to Bitcoin Core developer and Ciphrex Co-CEO, Eric Lombrozo, “Segregated Witness is the biggest extension of the protocol to date.”
Segregated Witness
Segregated Witness is a proposed upgrade to the Bitcoin protocol starting fourth dimension introduced past times Bitcoin Core and Blockstream developer, doctor Pieter Wuille, at the Scaling Bitcoin conference inwards Hong Kong inwards Dec of 2015. The technological excogitation separates signature information from Bitcoin transactions. This has several advantages, including — only non express to — a malleability fix, to a greater extent than flexible programmability, in addition to an effective block size bound increase.
“It's the most pregnant improvement to the protocol to date, in addition to lots of exciting innovations expire possible every bit a result,” Lombrozo told Bitcoin Magazine. “We're going through a catamenia of tremendous excogitation in Bitcoin — the greatest innovations since Bitcoin’s inception are taking house correct now.”
Segregated Witness has been inwards the pipeline for almost year. Wuille started coding it inwards Nov 2015, in addition to was joined past times Lombrozo, Johnson Lau in addition to several other Bitcoin Core developers inwards the next months. Counting almost 5,000 lines of code, Segregated Witness was completed concluding April.
Since that time, the proposed excogitation has been land of written report to rigorous checks in addition to analysis. Lombrozo explained:
“We’ve done a lot of review, in addition to a lot of testing. We’ve had 3 dedicated Segregated Witness examination networks, in addition to it has been successfully running on Bitcoin’s master copy testnet since May. Additionally, compact blocks had to travel developed in addition to integrated inwards Bitcoin Core to mitigate latency in addition to bandwidth issues. This was included inwards the latest version, 0.13.0.”
Activation
Segregated Witness is a proposed soft fork; a alter that technically makes Bitcoin’s protocol rules to a greater extent than restrictive.
Activation volition follow the standards every bit established by Bitcoin Improvement Improsal (BIP)9. This agency that, inside a unmarried difficulty catamenia of 2016 blocks (about ii weeks), at to the lowest degree 95 per centum of blocks must travel mined past times a miner that signals back upward for Segregated Witness. If this threshold is reached, the next difficulty catamenia allows everyone who wants to upgrade the peril to job so. After that, Segregated Witness back upward is activated, in addition to Segregated Witness transactions are accepted past times Bitcoin miners.
Signaling volition start on Nov 15. In the earliest possible scenario, this agency that Segregated Witness could activate past times mid-December. That seems somewhat unlikely at this time, however. Influenza A virus subtype H5N1 relatively novel Chinese mining puddle — ViaBTC — lately indicated it volition non back upward a Segregated Witness soft fork. As ViaBTC currently controls almost ix per centum of all hash mightiness on the network, it could effectively block activation — assuming it remains to a higher house at to the lowest degree five percent.
Lombrozo indicated that the Bitcoin Core evolution squad is non besides worried, however.
“Changes to the consensus rules are hard past times design,” he said. “In this case, I holler back the benefits vastly outweigh the risks, every bit Segregated Witness enables a bunch of novel excogitation inwards Bitcoin that volition ameliorate scalability in addition to volition allow for to a greater extent than role cases. My promise is that miners volition appreciate these nifty benefits in addition to volition desire to convey wages of this pregnant improvement to the protocol.”
If Segregated Witness is non supported past times 95 per centum of hash mightiness past times Nov 15, 2017, it tin no longer activate. Until then, it’s unlikely that Bitcoin Core developers volition nowadays an option proposal, Lombrozo said.
“We've worked rattling hard to uncovering a path forwards that gives everyone inwards the ecosystem something they want,” said Lombrozo. “It's non ever possible to delight everyone, only we've made a nifty effort. We seat this forwards for the community. I promise the community appreciates our function in addition to likes what we've done. At this point, it's inwards the community's hands to create upward one's hear its fate.”
