Summary
Antoine Poinsot and the Bitcoin Core team have disclosed a vulnerability within Bitcoin Core versions prior to 25.0, alongside announcing a new security policy aimed at enhancing transparency and security through regular updates on potential system vulnerabilities. Full details of the disclosed vulnerability and the new policy can be found on Bitcoin Core's website and their security advisories page, respectively.
Ava Chow highlighted the availability of Bitcoin Core version v28.0rc2 binaries, marking a significant step towards the final release of this new major version, with details and preliminary release notes accessible on Bitcoin Core's official website and GitHub. This update signifies the release candidate stage, crucial for rigorous testing and final adjustments before the official launch.
ZmnSCPxj presented the SuperScalar mechanism, a novel construction for efficient offchain liquidity allocation in the Bitcoin Lightning Network, which utilizes Decker-Wattenhofer decrementing-nSequence mechanisms, timeout trees, and laddering strategies to address the Last-Mile Problem (LMP) without blockchain consensus changes. More in-depth discussion on this mechanism and its implications for the Lightning Network can be explored at DelvingBitcoin.org.
Finally, halseth introduced the utxozkp tool, advancing privacy in Lightning Network channel announcements by enabling zero-knowledge proof of UTXO set inclusion. This development not only enhances privacy but also serves as a potential anti-DOS mechanism. The tool, based on the RISC Zero STARK platform and the Utreexo data structure, is still in its early stages, with details available for review on GitHub.
