Quantum Also Adds Proof-of-Ownership Headaches

The development team at Near One warns that quantum computing poses a dual threat to blockchains: not only can it compromise cryptography, but it also creates uncertainty regarding proof-of-ownership for assets. CTO Anton Astafiev notes that protocols may struggle to distinguish between rightful owners and attackers, necessitating difficult decisions on freezing compromised wallets. To address this, NEAR is researching zero-knowledge proofs to verify ownership securely and implementing the FIPS-204 quantum-safe signing system. While other networks like Ethereum and Solana are also developing post-quantum safeguards, the industry continues to debate the timeline and severity of these future cryptographic threats.
