Quantumproof blockchain

This invention describes a method for tracking public keys and transactions on a blockchain, specifically Bitcoin. It involves maintaining a central record (a hash table) that links fixed public keys to individual users and flags any associated malicious activity. The claims narrow the invention to this specific tracking and identification system, rather than a general quantum-proof blockchain.

Why it matters: The general threat of quantum computers breaking current blockchain cryptography has become more urgent since 2024. While the claims describe a specific tracking system, not a quantum-resistant blockchain, this increased threat makes any complementary security layer for existing systems more relevant.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSoftware logic, blockchain integration, cryptographic expertise
