Purse.io, a blockchain-based commerce platform, also offers a solution for Bitcoin's expansion technology 'extension blocks'. Its team of developers has proposed a blockchain scaling solution, extension blocks. The solution emphasises the ability to reconcile the two camps of the Bitcoin scaling debate by separating block capacity from the network's consensus rules, essentially allowing peers in the network to limit block capacity in a way that is consistent with their own version. Bitcoin Core developer Luke Dashjr has said that Purse's initial proposal to expand the block specification may "create a lot of additional technical debt", and Johnson Lau, author of an earlier proposal to expand blocks, has said that logically, such as SegWit is not secure enough, and that such a BIP would only be worse.
