ETH 2.0 Validator Says Medalla Testnet Incident Was a “Learning Experience”  

Prsymatic Labs, the validator in question, said the ETH 2.0 network will release as planned and that any rumors of its death were greatly exaggerated. Prysmatic Labs’ editor Raul Jordan, in a release, said the launch timetable for ETH 2.0 remains on track.

For the uninitiated, the Medalla testnet, the final multi-client testnet before ETH 2.0’s phase 0 launch, was halted halt on August 14 when a bug took most of the testnet’s validators offline.

One of the six Medalla servers was affected at the time, with the service stating the time of the day as one ahead into the future. This caused the system to average out the mishap by recording the time on all of the servers ahead by four hours.

“Validators incorrectly proposed blocks and attestations for future slots,” said Prysmatic’s official incident in a statement. It added that the bug affected everyone using the Prysm client, meaning a majority of users.

However, the risk has since passed. Jordan said the bug led to an eventual “carnage,” with over 3000 slashing events and all our internal validators slashed.” He then called the failure as “the best thing to happen to a testnet” as the incident on a mainnet would have meant dire consequences for Ethereum and loads of bad PR for the network.
