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.
