Projects detail

B-Harvest is working on 4 consecutive projects to strengthen the validator operation of Tendermint/Cosmos-SDK based blockchains. We want to share some progress on those projects.

1. Tendermint ADR 50 : Improved Trusted Peering

• brief introduction : strengthening trusted, internal, persistent peers by introducing unconditional_peer_ids and persistent_peers_max_dial_period
• status : spec PR accepted, implementation PR accepted
• workloads : about 4 weeks
• grant : $10,000

2. Cosmos-SDK ADR 16 : Validator Consensus Key Rotation

• brief introduction : allow validators to replace their consensus key
• status : spec PR accepted, implementation on the way
• workloads : about 8 weeks
• grant : $20,000

3. Tendermint ADR 51 : Double Signing Risk Reduction

• brief introduction : reduce double signing risk of validators by checking recent block data to check the existence of the validator's consensus key
• status : spec PR accepted, implementation on the way
• workloads : about 4 weeks
• grant : $10,000

4. Tendermint ADR 52 : Tendermint Mode

• brief introduction : introducing "Tendermint Mode" which allows operator to select mode(fullnode/validator/seednode) for each specific functionality to efficiently use resource and prevent mistakes from operators
• status : spec PR accepted, implementation on the way
• workloads : about 4 weeks
• grant : $10,000
