ANECDOTE

Medalla Testnet Incident

  • The Medalla testnet experienced a critical bug causing most nodes to go down, validators to stop validating, and a mass slashing event.
  • This was caused by a time server bug and a subsequent flawed fix, highlighting the importance of multi-client testnets.
INSIGHT

Mainnet vs. Testnet Bug Response

  • If the Medalla bug occurred on mainnet, the dynamics would differ due to higher stakes.
  • Faster reactions, client-switching, and better communication would likely occur in a real-money scenario.
ADVICE

Contribute to Medalla

  • Join the Medalla testnet by running a node or validator to contribute to a safer mainnet launch.
  • Report any issues or bugs encountered to help identify and resolve critical problems before real ETH is at stake.
