Ethan Heilman

ResearcherCrypto

Cryptographer who has spent a decade stress-testing Bitcoin's foundations: the 2015 eclipse-attack research that hardened its peer-to-peer network, the TumbleBit private payment hub, BIP-347 (OP_CAT in Tapscript), and co-authorship of BIP-360, Bitcoin's first merged post-quantum proposal. A researcher at Cloudflare and MIT Digital Currency Initiative fellow, he works on the cryptographic upgrades a money must make to stay secure over the long run.
