Solana’s Outage and Future — CoinShares’ Perspective
Recently Solana experienced its first outage in over 11 months. An infinite loop was propagated across the network’s validators due to a faulty implementation inside of the core software via the Berkley Packet Filter which is the mechanism to deploy, upgrade and execute programs on Solana. Block production halted, impeding the chain’s progress (in layman’s terms, it went offline). Validators then manually verified, inside of a Google Sheet, a snapshot of the last valid block. For the chain to restart, at least 80% of validators began running the patched software for blocks to be added to the chain.
