Justin Sun Warns Quantum Threat Could Hit Crypto Within 2 Years as TRON Pursues Resistance

TRON CEO Justin Sun warned that quantum computers could threaten cryptocurrencies in as little as one to two years. Sun said advances in fault-tolerant quantum machines could use Shor’s algorithm to break public-key cryptography, the backbone of blockchain networks, including ECDSA signatures many rely on; he added that many crypto assets are held in addresses with exposed public keys, and attackers could collect encrypted data now and decrypt it later. Current quantum computers cannot break these networks. TRON announced last month that post-quantum cryptography, designed to resist quantum attacks, is available on its testnet.
