Cosmos Labs rolled out the Ledger Security 2026.1 suite, integrating ML-DSA signature algorithms standardized under FIPS 204. According to crypto-economy.com, the release is designed to future-proof the network against emerging quantum computing threats.

The update introduces core upgrades to Cosmos SDK v0.55.0 and CometBFT v0.40.0, alongside the new cosmos/kms v0.1.0 module. This technical milestone facilitates the transition of validators to post-quantum signature algorithms once a two-thirds voting power threshold is achieved.
