![]() However, the wallet would still see the transaction and recognise it as valid once it was included in the blockchain. From the perspective of old wallets, the new style transactions would be missing a signature. In addition to this, old wallets and new wallets could seamlessly interact with each other and the upgrade was entirely optional: users could either upgrade to SegWit, or continue using the network as before. ![]() The network could get to 2 MB blocks, yet we avoided the problem of the upgrade being incompatible. To those that understood it, SegWit seemed like a brilliant win-win proposal. However, Luke clearly had a very strong technical understanding of Bitcoin, and his apparent non-linear thinking, which made him see things differently from others, may have helped him conceive of this hack that the other developers couldn’t quite work out. To some extent, the committed Catholic and father-of-seven was the Cassandra of the technical community exceptionally strident. Luke was not at all scared of standing out from the crowd with his non-consensus opinions. Luke was regarded as one of the most extreme small blockers and was another hate figure in the large block community, alongside Gregory Maxwell. This meant that the signature data received a discount in the calculation, but the overall limit would be around 2 MB, which is of course what many people seemed to want: a blocksize limit increase to around 2 MB.Ī Florida-based Bitcoin developer called Luke Dashjr had figured out a hack, which made SegWit possible as a compatible (softfork) Bitcoin upgrade. The weight limit was defined as four times the amount of non-signature data in bytes plus the amount of segregated signature data, in bytes. ![]() Clients that upgraded to SegWit would see a new block, which included these signatures for these newer clients, the old 1 MB blocksize limit was removed and replaced by a 4 million unit “weight limit”. SegWit was a new transaction format, where the signature would not need to be included in the old block, which still had a 1 MB limit. This signature is typically the largest part of the transaction, based on the amount of data. A Bitcoin transaction consists of various components, one of which is the signature, authorising the spend. it was a softfork rather than a hardfork). SegWit is a way of increasing the Bitcoin blocksize, without the new client being incompatible (i.e. 230000006399 behavior Effects 0.In the first session of the second day of Scaling Bitcoin Hong Kong, during one of the prime slots, Bitcoin developer Pieter Wuille gave a talk on something called Segregated Witness (SegWit).239000008186 active pharmaceutical agent Substances 0.000 description 2.238000010200 validation analysis Methods 0.000 description 5.238000005516 engineering process Methods 0.000 description 6.238000004364 calculation method Methods 0.000 description 7.Status Active legal-status Critical Current Anticipated expiration legal-status Critical Links ![]() Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)
