Summary

Oct 27 - Nov 2, 2025

Our weekly newsletter is focused on keeping you updated on what's new in Bitcoin, and summarizes the bitcoin-dev, lightning-dev and delving bitcoin mailing lists

The segOP proposal by Defenwycke marks a pivotal enhancement in Bitcoin transactions, introducing a segregated, full-fee data lane for structured on-chain data storage, reminiscent of Segregated Witness (SegWit) but focused on addressing the limitations of the current transaction format regarding arbitrary data storage. This proposal, designed as a soft fork, aims for backward compatibility and fair fee assessment, incorporating a new transaction section committed via OP_SUCCESS184 and employing TLV encoding for data management, thereby tackling inefficiencies and setting the stage for future Bitcoin innovations (source).

Juan Alemán suggests a significant restructuring of the Bitcoin repository to mitigate political influence on policy decisions, proposing the separation of consensus rules from policy implementations to ensure decentralization. This approach involves creating a new repository focused on consensus, aiming to accommodate various client needs and maintain the project’s neutrality, thereby addressing the concerns raised by the controversial changes in Bitcoin Core version 30 and averting potential network forks (source).

Jakob Widmann introduces Anticipation Transactions (ATX) to address Bitcoin's scalability issues, proposing a novel mechanism that bypasses the Lightning Network’s complexities by leveraging the mining infrastructure. This system aims to confirm transactions with a significant percentage of mining hash power, introducing a timelock feature for recipient actions and an innovative fee structure to incentivize miner participation, thereby enhancing Bitcoin’s transaction processing capabilities without necessitating immediate blockchain settlement (source).

Lastly, the v31.0 release of Bitcoin Core celebrates a decade since the adoption of libsecp256k1 for ECDSA signature validation, highlighting significant performance enhancements over OpenSSL. Continuous optimizations have made libsecp256k1 vastly superior in verifying ECDSA signatures on the secp256k1 curve, showcasing the focused efforts to improve Bitcoin's efficiency and security. This milestone underscores the importance of specialized libraries in blockchain technology and their role in facilitating secure and rapid transactions (source).
