Solana came within roughly 4.5 percentage points of losing transaction finality early Wednesday, when 28.83% of staked SOL went delinquent, according to staking protocol Marinade Finance.
Marinade said the episode affected 90 validators and cost them a combined 333 SOL in rewards. The reported delinquency remained below the 33.34% threshold Marinade said would stop finality. Solana’s public status page listed no incident for Aug. 12.
On Solana, a block becomes confirmed after at least 66% of stake votes on it; finalization also requires at least 31 subsequent confirmed blocks, according to infrastructure provider Helius. The function most directly threatened by losing more than one-third of stake is therefore confirmation and finality: an online leader can still produce a “processed” block before it receives the stake-weighted votes required for confirmation.
Marinade said that if delinquency had exceeded one-third, “nothing finalizes.”
PeeringDB identifies Teraswitch as the operator of AS20326. Marinade said AS20326 carried 118.89 million SOL — more than one-quarter of all staked SOL — and that 94% of it went dark at once.
