Decentralized data network Bluzelle (BLZ) discovered a bug in the Tendermint consensus algorithm used by the Cosmos (ATOM) interchain protocol.
According to a Bluzelle announcement shared with Cointelegraph on July 6, the firm discovered a bug in Tendermint during its validators competition. The competition, which involved 220 participants maintaining a Tendermint-based a testnet, at one point saw the blockchain halt completely due to the bug.
