Fabian Jahr

Fabian Jahr is a Berlin-based Bitcoin Core (the standard reference software for the Bitcoin network) developer. His work spans a wide range of efforts to improve the stability and scalability of the Bitcoin protocol — from research on Schnorr signature–based technologies, to in-depth review of critical pull requests, to development of ASMap (a technology that improves the geographic and network decentralization of nodes). In recognition of his research, he was recently selected as a CISA (Cross-Input Signature Aggregation, a Bitcoin signature aggregation technique that can significantly improve transaction efficiency) Research Fellow at the Human Rights Foundation (HRF), and published a 38-page industry report analyzing the impact CISA could have on the Bitcoin ecosystem. At this conference, he will draw on this experience to discuss recent developments in Bitcoin Core, and what the next generation of protocol upgrades — including CISA and Schnorr signatures — means for Bitcoin.
