Project Eleven Quantum Threat Report: Cryptographic algorithms such as ECDSA may be cracked between 2030 and 2033

Foresight News reports that Project Eleven's "The Quantum Threat to Blockchains - 2026 Report" points out that the rapid development of quantum computers is posing a serious threat to blockchain security. Once a "Cryptographically Relevant Quantum Computer" (CRQC) emerges, the Shor algorithm can quickly break ECDSA (used by Bitcoin and most public blockchains) and RSA asymmetric encryption. Q-Day (quantum decryption day) is expected to arrive between 2030 and 2033, at which point trillions of US dollars in on-chain assets will be at risk. Since blockchain public keys are static for extended periods and cannot be rolled back, migration is extremely difficult. The report recommends immediately launching post-quantum cryptography (PQC) migration, including lattice-based, hash-based, and other quantum-resistant signature schemes, and gradually transitioning via hybrid solutions to prevent a full-blown quantum threat.
