Solana pitches Quantumglow to protect Alpenglow from quantum attacks

Solana has promoted Quantumglow, a proposed post-quantum adaptation of Alpenglow designed to protect consensus while preserving the network’s fast finality. Quantumglow proposes changes to validator signatures and block authentication without announcing a deployment date. Anza published the underlying research in July, before Solana’s latest video explainer. Alpenglow’s mainnet activation is separate from the proposed post-quantum changes to its cryptography. Bitcoin’s BIP-360 targets exposed public keys, with additional signatures needed for more complete protection. Solana Developers described the proposal in an Oct. 22 video post, presenting it as a way to secure agreement between validators against quantum attacks. Solana’s main account shared the explainer and said the network “has been early in quantum readiness and remains ahead in its preparation.” https://twitter.com/solana_devs/status/2113308459860988100 Neither announcement supplied an activation date or identified a Quantumglow-specific…
