July 6, 2020

The decentralized data network Blood cell (BLZ) discovered a bug in the consensus algorithm Delicate mint is used by the Cosmos Inter-Chain Protocol (ATOM).

According to a Bluzelle announcement shared with Cointelegraph on July 6, The company discovered a bug in Tendermint during its validation competition. The competition, in which 220 participants took part, maintained a test network based on tenders at a certain point in time saw the blockchain come to a standstill as a result of a mistake.

Validators who took part in the competition They were unable to resume their activities even after the blockchain was restarted. Bluzelle sent Cosmos a detailed bug report after the June incident The problem was solved on July 2nd. The company’s chief technology officer and co-founder, Neeraj Muraka, said:

“Although our team’s discovery of the error threatened to derail the entire validation competition, it turned out to be a valuable exercise for everyone involved.

Bluzelle CEO, Pavel Bains explained that although Bluzelle is not a Cosmos sidechain, the network in question was created using the Cosmos software development kit and therefore use tendermint. He also mentioned that as soon as the next communication protocol between Cosmos blockchains has started, Bluzelle will also use it to connect to other chains.

Bluzelle started its mainnet in April. The company claims that This network combines some of the functions of edge computing with Distributed Accounting Technology (DLT). Bluzelle’s blockchain is divided into shoals that can also be created based on your geographic location to help reduce network latency.
