SignCTRL is a high availability solution for Tendermint that enables the creation of a highly available, self-managing set of validators that uses the blockchain itself as a perfectly synchronous communication line for double-signing protection.
⚠️ SignCTRL is still beta software and not considered ready for production, yet. Use at your own risk.
- Built-in double-signing protection
- Very lightweight (no additional communication overhead for coordination work)
- No more sentry nodes are needed, as the validators in the set back each other up
- Minimal setup requires only two nodes
- Go
v1.16+ - Tendermint
v0.34+(with protobuf support)
