Mithril signer 1.0.0: production-ready on @Cardano mainnet The Mithril signer has reached version 1.0.0, its first stable release, delivered with the 2617.0 distribution. It is now officially production-ready on the Cardano release-mainnet network. This milestone follows nearly three years of continuous development. Since the mainnet beta launch in July 2023, the signer has been progressively improved, hardened, and validated in production by the community of stake pool operators running it on release-mainnet. Version 1.0.0 reflects that the software now meets the bar for stability and operational maturity across four dimensions: Stability: a settled public API, configuration model, and operational behavior Performance: validated across supported platforms, including Linux x86_64 and Linux ARM64 Security: the outcome of many iterations of review and hardening of the signing pipeline Reliability: suitable for long-running production deployments on release-mainnet From this release onward, the Mithril signer adopts semantic versioning. Any backward-incompatible changes will be communicated in advance through dedicated dev blog posts, giving operators clear visibility into upgrade implications. Operators running a signer on release-mainnet or release-preprod should upgrade to 1.0.0 as part of the 2617.0 distribution rollout. No configuration changes are required. Thanks to the stake pool operators who have run the Mithril signer and contributed feedback since its earliest iterations. This stable release is a direct result of their engagement and of the collaboration that continues to strengthen the Cardano ecosystem. #Cardano #Mithril #Blockchain #Infrastructure #StakePoolOperators
