Long-Term Support For Andrew Toth

OpenSats is pleased to announce its long-term support for Andrew Toth in recognition of his ongoing contributions to Bitcoin Core. His work has focused on performance and privacy enhancements that improve the experience of running a fully validating node.

Andrew is an active, long-time contributor to Bitcoin Core, with contributions spanning initial block download (IBD), block-connection logic, caching behavior, and RPC performance.

His improvements to IBD and block-connection speed for pruned nodes have provided significant changes for users operating with limited disk resources, and he has continued refining critical performance areas of the codebase as network conditions and hardware constraints evolve.

In addition to working on performance, Andrew authored BIP 374 and co-authored BIP 375, which together help support silent payments through PSBTs.

He has also been involved in testing and reviewing Bitcoin Core's private-broadcast work, with the goal of improving network-level privacy for users who operate their own nodes.

Andrew's other contributions to projects such as bitcoinjs, rust-bitcoin, and Electrum Personal Server reflect his commitment to the benefit of the Bitcoin ecosystem.

I’m grateful and honored to receive this grant to continue my work on Bitcoin Core. Performance and privacy are essential for using Bitcoin in a self-sovereign way, and I’m glad to see these efforts recognized and supported.

With support from this LTS grant, Andrew plans to continue work on several areas of Bitcoin Core, including:

• Continued improvements in IBD and block-connection performance.
• Advancing private transaction broadcast and contributing to the follow-up changes to make it reliable for users.
• Refining caching and validation code to simplify performance-sensitive paths and improve maintainability.
• Providing ongoing review across validation, performance, and privacy-related changes within Bitcoin Core.

Our mission at OpenSats is to provide sustainable funding for the builders and maintainers of critical open-source infrastructure within the Bitcoin ecosystem.
