Olaoluwa Osuntokun has proposed the addition of Elliptic Curve operation op codes to Bitcoin's scripting language to enhance its smart contract capabilities, utilizing Taproot to enable more dynamic and versatile applications like optimized Discreet Log Contracts and EC-based sigma protocols. This advancement, detailed in the Bitcoin Improvement Proposal accessible here, aims to significantly extend Bitcoin's scripting functionalities and is accompanied by a reference implementation for btcd found here.

Meanwhile, the release of Bitcoin Core version v29.1rc2, as announced by fanquake, introduces the latest binaries and source code available for community testing here and here respectively. This step is crucial for identifying critical issues before the official release, emphasizing the importance of community feedback through the GitHub issue tracker.

In a separate development, Ben Westgate has suggested integrating BIP-0093 with BIP-0085 to generate codex32 backups from BIP-0032 master keys, enhancing deterministic wallet backups and seed management. The proposal, which aims to standardize the use of codex32 for better error correction and secret sharing capabilities, is elaborated on here and is supported by a draft PR for Bitcoin Core, available at PR 32652.

The bitcoinfuzz project, initiated by bruno and further developed with contributions from Erick Cestari and Morehouse, underscores a concerted effort to bolster security across Bitcoin and Lightning Network implementations through differential fuzzing. Having identified over 35 bugs in key projects, the venture seeks to integrate with OSS-Fuzz and enhance its infrastructure for broader fuzzing capabilities, as documented here. This endeavor exemplifies the ongoing commitment within the Bitcoin community to refine and secure its underlying technologies.
