Project Eleven is is applying post-quantum cryptography (PQC) to existing protocols, starting with Bitcoin. This will ensure they remain secure even when classical cryptography fails. Its first solution is yellowpages, a post-quantum proof of Bitcoin ownership that allows users to instantly generate quantum-resistant keys and securely link them to existing Bitcoin addresses.
SpaceComputer is a satellite-based blockchain verification layer project that provides secure and reliable transaction verification and threat protection for interplanetary finance by deploying space-based infrastructure to build an “orbital root of trust”.
