Solana and Newer Blockchains May Be Better Positioned Than Bitcoin for Quantum Computing Threats

Key Points

1. Newer blockchains such as Solana, Sui, and Near use EdDSA, which offers enhanced security against quantum attacks compared to ECDSA used by Bitcoin and Ethereum.

2. Quantum computers running Shor’s Algorithm can rapidly factor large numbers, threatening cryptographic systems like RSA and ECDSA, making Bitcoin and Ethereum vulnerable.

3. Governments are mandating the deprecation of vulnerable algorithms like ECDSA and RSA by 2030-2035 to protect digital assets, pushing blockchain communities to prioritize quantum-resistant upgrades.

4. EdDSA avoids vulnerabilities like weak random number generation and nonce reuse found in ECDSA, making it more secure and easier to implement post-quantum cryptographic standards.

5. Experts emphasize the urgency of post-quantum upgrades, with some predicting the need for action by 2030 or 2035 to maintain blockchain security and credibility.
