Signing Provider for TMKMS overview


In Proof-of-Stake (POS) blockchains such as the ones that rely on the Ignite (formerly, Tendermint) or the Evmos stacks, validator nodes do not expend resources to “mine” the next block. Rather, they validate and sign proposals and votes. The new requirement on the operators of validator nodes is to maintain long-lived keys online securely such that they are always available.  

Key Features


Maintain keys online with SaaS

DSM is available as a global cloud service with centralized visibility and control. Validator keys can be securely managed and retrieved online.


Cluster-based architecture with HA/DR

The platform maintains high availability, based on a cluster architecture with in-built resilience. It also supports disaster recovery to avoid loss of digital assets.


Seamless integration with TMKMS

The Fortanix Signing Provider for TMKMS solution includes an integration of Fortanix DSM SaaS into Tendermint KMS (TMKMS) which is an open-source project freely available under the Apache 2.0 license.
