Bluzelle (BLZ), a decentralized data network, has spotted vulnerability in the Tendermint consensus algo employed by the Cosmos (ATOM) interchain covenant.
The company identified a glitch in Tendermint in the course of validators competition, which saw 220 competitors assess a Tendermint-powered testnet.
In fact, the vulnerability caused the blockchain to halt completely during the competition.
Validators who took part in the contest were not able to restart their work even after bring back the blockchain live. Bluzelle forwarded a detailed bug report to Cosmos, after the crash happened in June, and the issue was resolved on July 2. The tech firm’s CTO and co-founder, Neeraj Muraka, said:
“Although our team’s uncovering of the bug threatened to derail our entire validator competition, it proved to be a valuable exercise for everyone involved. […] A competition intended to incentivize validators to stake and participate in consensus suddenly became an impromptu bug bounty, with heads coming together to diagnose and resolve the problem.”
Bluzelle CEO Pavel Bains has pointed out that Bluzelle is not a Cosmos sidechain and the network was created using Cosmos software builder. Therefore, it uses Tendermint.
Additionally, he highlighted that Bluzelle also intends to utilize Cosmos after the latter shifts to Inter-Blockchain Communication Protocol for linking with other chains.
Bluzella rolled out its main network in April. The company has pointed out that its network has brought together some feature of edge computing and distributed ledger technology.
The Bluzelle blockchain is segregated into clusters that can also be set up on the basis of geographical location, leading to negligible computing latency.
