SignCTRL

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.

⚠️ Be mindful of key security as SignCTRL currently only supports Tendermint's file-based signer. Make sure to properly secure your validator instance from unauthorized access.

Why SignCTRL?

1. Built-in double-signing protection.
2. Very lightweight due to not introducing any additional communication overhead for coordination work.
3. No more sentry nodes are needed, as the validators in the set back each other up.
4. A minimal setup requires only two nodes to be run.

Requirements

• Go v1.15+
• Tendermint v0.34+ (with protobuf support)
