BLZ – Decentralized data network Bluzelle discovered a bug within the Tendermint consensus algorithm employed by the Cosmos [ATOM] interchain protocol.
In line with a recent Bluzelle announcement, the firm discovered a bug in Tendermint within its validators competition. The competition, involved 220 participants maintaining a Tendermint-based a testnet, at one point saw the blockchain halt completely due to the bug.
Bug Is Successfully Fixed
Validators participating within the competition were unable to resume their activities even after the blockchain was restarted. Bluzelle sent an in depth bug report back to Cosmos after the incident happened earlier in June. The reported issue was thereby fixed later on 2nd July. The firm’s chief technology officer and co-founder, Neeraj Muraka, added:
“Although our team’s uncovering of the bug threatened to derail our entire validator competition, it proved to be a valuable exercise for everybody involved. […] a contest intended to incentivise validators to stake and participate in consensus suddenly became an impromptu bug bounty, with heads coming together to diagnose and resolve the matter.”
Bluzelle CEO Pavel Bains added that – while Bluzelle isn’t a Cosmos sidechain – the network in question was built using the Cosmos software development kit and consequently uses Tendermint. Moreover, he added that within some upcoming time, till Cosmos Inter-Blockchain Communication Protocol is launched, Bluzelle will also use it to connect to other chains.
Bluzelle launched its main network earlier in April this year. The company claims that this network combines a number of the features of edge computing with DLT [Distributed Ledger Technology]. The Bluzelle blockchain is split into swarms which will even be created supporting their geographical location, allowing lower computation latency.
