Nearly 29% of staked SOL went offline early Wednesday after a routing fault at hosting provider Teraswitch, bringing Solana within 4 percentage points of the 33% threshold at which the network stops finalizing blocks. The network recovered without a full halt.
A critical consensus flaw allowed invalid blocks onto the Ravencoin blockchain starting August 7 at block height 4,487,776. Two mining pools controlling majority hashpower are building a replacement chain from before the exploit, threatening to reverse four days of deposits, withdrawals, and payments.
A demonstrated consensus flaw let invalid blocks onto Ravencoin starting at block height 4,487,776 on August 7. Pools controlling majority hashpower are mining a replacement chain, putting deposits and withdrawals made since then at risk.
