Overview
- Mysten Labs’ Kostas Chalkias cautions that quantum computers running Shor’s algorithm could eventually derive private keys from ECDSA, with reports warning that legacy wallets expose as much as a quarter of Bitcoin to higher risk.
- NIST and ENISA are advancing post‑quantum cryptography standards, and coverage cites recommendations to phase out ECDSA and RSA by roughly 2030–2035, yet major networks have been slow to implement upgrades.
- Analysts cited say moving Bitcoin and Ethereum to quantum‑resistant signatures would require hard forks, new address formats, and large‑scale fund migrations that pose significant technical and governance challenges.
- Only a handful of projects are testing quantum‑resistant schemes today, including Sui, Ethereum, and Algorand, with Sui working on backward compatibility, while EdDSA‑based chains such as Solana, Sui, and Near are described as better positioned for upgrades.
- A Cornell study referenced in the coverage finds AI agents tied to blockchains can be manipulated via tampered memory or prompts, underscoring broader AI‑enabled threats as cybercriminal tools proliferate.
