Biography
Danno Ferrin is a cryptography and protocol engineer with over 20 years of experience building secure, large-scale systems. His work focuses on post-quantum cryptography migration -- the practical challenge of replacing the cryptographic algorithms that underpin today's digital infrastructure before quantum computers can break them. He has hands-on experience implementing NIST-standard PQC primitives at the protocol level, from consensus and transaction signing to key management and developer tooling.
Danno has spent his career at the intersection of cryptography, distributed systems, and protocol design. He has held engineering leadership roles at Tectonic Labs, the Ethereum Foundation, Swirlds Labs (Hedera Hashgraph), ConsenSys, Reddit, and Google, and has contributed to open standards across multiple ecosystems.
