Years into the great Bitcoin scaling debate no solution is in reach. Neither bigger blocks nor Segregated Witness have anywhere near consensus support. With the conflict escalating, a Bitcoin fork has become a real possibility. Electrum Developer Thomas Voegtlin joined us to discuss the state of the Bitcoin scaling debate. We discussed Bitcoin Unlimited, ASICBoost, SegWit activation without miner support and how a Bitcoin fork could play out. Possible outcomes include that Bitcoin Unlimited gains a majority of hashing power and starts mining bigger blocks. In the event of a fork, a proof-of-work change could be done to defend the minority chain from miner attacks. And lately a proposal was brought forward to activate SegWit without the support of the hashing power. Topics discussed in this episode: ASICBoost and its potential role in the conflict How a Bitcoin fork could happen How to split coins in case of a fork How UASF could be used to activate SegWit without miner support Requirements for UASF to be safe How Electrum would handle a fork Episode links: Electrum Bitcoin Wallet ASICBoost – Hacker Noon Bitcoin's New Controversy: The AsicBoost Allegations Explained - CoinDesk Timo Hanke on ASICBoost and SegWit Non-Activation From AsicBoost to UASF: Greg Maxwell on Bitcoin's Path Forward - CoinDesk [bitcoin-dev] Thomas Voegtlin: Soft Fork Threshold Signaling Proposal UASF Working Group [bitcoin-dev] Greg Maxwell: I do not support the BIP 148 UASF Thomas Voegtlin: Electrum, SPV Wallets And Bitcoin Aliases — Epicenter This episode is hosted by Brian Fabian Crain and Sébastien Couture.
