Bitcoin Optech newsletter #364 is here: - summarizes a vulnerability affecting old versions of LND - describes an idea for improving privacy when using co-signer services - examines the impact of switching to quantum-resistant signature algorithms on HD wallets, scriptless multisig, and silent payments - summarizes popular Q&A from Stack Exchange - Optech Newsletter #364 Recap Matt Morehouse posted to Delving Bitcoin about a vulnerability affecting past versions of LND that he previously responsibly disclosed... Jurvis Tan posted to Delving Bitcoin about research he performed with Jesse Posner into improving the privacy and security of multisig collaborative custody... Jesse Posner posted to Delving Bitcoin several links to research papers that indicate that quantum-resistant signature algorithms provide comparable primitives to those currently used in Bitcoin... Selected Q&A from Bitcoin Stack Exchange: - How does Bitcoin Core handle reorgs larger than 10 blocks? - Advantages of a signing device over an encrypted drive? - Spending a taproot output through the keypath and scriptpath? Bitcoin Optech will host an audio recap discussion of this newsletter on Riverside.fm Tuesday at 16:30 UTC. Join us to discuss or ask questions!
