Cypherpunk Legend Adam Back Approves Ethereum's Post-Quantum Shift

Bitcoin pioneer Adam Back has endorsed Ethereum's shift toward post-quantum security, as the blockchain replaces its custom Poseidon hashes with more proven cryptographic standards.

Cypherpunk legend and Bitcoin pioneer Adam Back has endorsed Ethereum’s cryptographic pivot away from custom Poseidon hashes in favor of time-tested security. The move addresses post-quantum vulnerabilities, aligning with Back’s long-standing advocacy for conservative cryptography. Ethereum’s shift prioritizes battle-hardened algorithms over novel designs, a decision Back co-signs as prudent for long-term network resilience.
