Summary

Nov 17 - Nov 20, 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

Recent discussions in the Bitcoin development community highlight several innovative proposals and tools aimed at enhancing the network's functionality, security, and user experience. The draft Bitcoin Improvement Proposal introduces a standard for on-chain identity publication using canonical CBOR payloads and a Poseidon-based nullifier_hash, alongside an optional Ed25519 signature wrapper for increased security, calling for community feedback on interoperability and security considerations (view the PR here). Concurrently, updates to the Bitcoin backbone focus on re-implementing BIP324, eradicating bugs, and introducing a simplified transaction relay stack and mempool buffer to optimize transaction processing and enhance resilience against DoS attacks, with detailed information available at bitcoinbackbone.org.

Innovative approaches are being explored to manage objectionable content on the blockchain, proposing consensus and client-level changes to allow node operators to filter and remove disagreeable content post-mining without compromising the blockchain's integrity. This discussion underscores the immutable nature of blockchain technology and the challenges in content moderation (more details). Penlock's public release introduces a tool for securely managing digital assets by mechanically splitting a 12-word seed phrase into a 2-of-3 backup format, enhancing user experience with a paper-optimized splitting algorithm and an on-paper error correction algorithm, further detailed at Penlock.

Moreover, discussions extend to theoretical and practical enhancements within the Bitcoin network, such as the cluster mempool proposal aimed at maximizing fee structures within the mempool and addressing quantum vulnerabilities by proposing different policy frameworks for handling quantum-vulnerable UTXOs post-"Q-day" (general thoughts on quantum vulnerabilities). Additionally, the development of raw₿it, a visual, node-based editor, revolutionizes learning and building Bitcoin transactions, offering an in-depth, hands-on learning experience through a user-friendly interface (explore raw₿it). These discussions and developments underscore a proactive and innovative approach to addressing current and future challenges within the Bitcoin ecosystem, fostering a collaborative environment for continuous improvement and adaptation.

  • There is concern over the stigma of disclosing AI use in Bitcoin Improvement Proposals.

  • The main issue is when and if to label BIPs with "AI use" due to ambiguities.

  • This situation indicates a broader dilemma on AI acknowledgement in research work.

  • Enhancing programming practices involves selecting random offsets from a prefill set.

  • Direct communication of offsets, like "offset=[0,1,2]," is theoretically simple but risks dishonesty.

  • The approach underscores designing robust systems that mitigate risks in collaborative environments.
