## Bitcoin Op Tech #3 Podcast Summary: Schnorr & Building on Bitcoin
This episode of the Bitcoin Op Tech newsletter (June 10, 2018) dives into several key developments impacting the Bitcoin ecosystem, including a proposed Schnorr signature format, updates on Bitcoin Core development, and a recap of the Building on Bitcoin conference held in Lisbon. The episode highlights ongoing efforts to improve Bitcoin's scalability, privacy, and developer tooling, while also addressing some immediate concerns regarding infrastructure vulnerabilities and relay fees. The discussion reflects a time when Bitcoin’s price was significantly lower than its current value, influencing considerations around minimum relay fees.
Main Topics Discussed:
- Schnorr Signatures: A detailed discussion of Peter Wolley's draft specification for Schnorr signatures, focusing on their potential to reduce signature size (approximately 10%), improve blockchain capacity, enable faster signature verification, and enhance privacy through signature aggregation.
- Bitcoin Core Minimum Relay Fees: Ongoing discussions to potentially reduce the minimum relay fee in Bitcoin Core, with Gregory Maxwell planning a pull request. A misunderstanding regarding signature size (71 vs. 72 bytes) was identified as a cause for some services creating underfunded transactions.
- Bitcoin Core 0.17 Development: The nearing conclusion of development for Bitcoin Core 0.17, with potential features including transaction output scanning, partial signature support, delayed transaction sending, and a Rust re-implementation of the Electron Server.
- Building on Bitcoin Conference Recap: Highlights from the Lisbon conference, including talks on merchant adoption, user experience for Lightning wallets, blind signatures, Lightning Network history, and Coin Join XT.
- Bitcoin Infrastructure Vulnerability: A disclosed vulnerability affecting older versions of Bitcoin Core (0.12 and earlier) requires users to check their infrastructure.
- Privacy Enhancements: Discussions around Coin Join XT and signature aggregation as potential privacy-enhancing technologies.
Key Quotes:
- "The proposal focuses on signature aggregation and acknowledges that it may be pursued later due to the complexity of other Bitcoin script improvements." - Regarding the Schnorr signature proposal.
- "Development of new features for Bitcoin Core 0.17 will soon cease to allow for testing and documentation." - Highlighting the impending end of development for a key Bitcoin Core release.
