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 Links mentioned in this episode: - Electrum Bitcoin Wallet: https://electrum.org/#home - ASICBoost – Hacker Noon: https://medium.com/@samcole_74219/asicboost-655a73d48ae4 - Bitcoin's New Controversy: The AsicBoost Allegations Explained - CoinDesk: http://www.coindesk.com/bitcoins-new-controversy-asicboost-allegations-explained/ - Timo Hanke on ASICBoost and SegWit Non-Activation: https://twitter.com/timothanke/status/849896505653706753 - From AsicBoost to UASF: Greg Maxwell on Bitcoin's Path Forward - CoinDesk: http://www.coindesk.com/asicboost-uasf-greg-maxwell-bitcoins-path-forward/ - [bitcoin-dev] Thomas Voegtlin: Soft Fork Threshold Signaling Proposal: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2017-April/014146.html - UASF Working Group: http://www.uasf.co/ - [bitcoin-dev] Greg Maxwell: I do not support the BIP 148 UASF: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2017-April/014152.html - Thomas Voegtlin: Electrum, SPV Wallets And Bitcoin Aliases — Epicenter: https://epicenter.tv/episode/069/ Sponsors: - Jaxx: Wallets that Unify the Blockchain Experience Across Devices - http://jaxx.io This episode is also available on : - Epicenter.tv: https://epicenter.tv/179 - YouTube: http://youtu.be/18QdbsSo8T8 - Souncloud: http://soundcloud.com/epicenterbitcoin/eb-179 Watch or listen, Epicenter is available wherever you get your podcasts.
