What Bitcoin’s Post-Quantum Migration Actually Requires
A new output type, a signature algorithm choice, a fee-market renegotiation, and a multi-year UTXO sunset. The engineering pieces of Bitcoin's PQC migration, and…
Ethereum’s Five Quantum Vulnerabilities and Who Owns Each Fix
One network, three cryptographic primitives, five layers, five different sets of owners. Ethereum as a worked example in reading a cryptographic inventory.
Why Signature Migration Needs the Longer Runway
A post-quantum plan is two migrations under one label. Sorting the signature work by who has to agree before you can change an algorithm…
Trust Now, Forge Later: The Signature Half of the Migration
Harvest Now, Decrypt Later sets its clock by data retention. The signature side of the quantum problem sets its clock by deployment lifetime, and…
