Quantum Computing Could Threaten Bitcoin by 2030
Bitcoin Quantum Computing Could Threaten Bitcoin by 2030Report warns quantum computers may break blockchain cryptography by 2033.Researchers say 6.9M Bitcoin may already be exposed to future quantum attacks.NEAR Protocol is preparing post-quantum upgrades to reduce long-term cryptographic risks. Project Elevens blockchain security report warns that quantum computing could threaten major crypto networks, including Bitcoin, within the next decade. In response, NEAR Protocol has started integrating post-quantum cryptography into its ecosystem. Quantum Computing Concerns Grow Across Crypto The report, titled “The Quantum Threat to Blockchains – 2026 Report,” said current blockchain cryptography used by Bitcoin, Ethereum, and Solana may become vulnerable as early as 2030 to 2033. Project Eleven referred to the potential arrival of a machine capable of breaking current encryption as “Q-Day.” Also, the project noted that breakthroughs in quantum hardware, error correction, and algorithm efficiency have also accelerated development beyond earlier expectations. The researchers added that these advances could reduce the computational resources needed to break encryption. To prevent this threat, the report argued that blockchains must migrate to post-quantum cryptography urgently because decentralized networks may require years to coordinate protocol upgrades, wallet migrations, and validator changes. Why Blockchains Face Unique Risks In particular, the researchers explained why blockchains are at risk, citing Shors algorithm as
