Cc9f267dcClaimSecurity firm Blockaid confirmed the Reth state-root calculation flaw was a code calculation error rather than an active exploit, with no stolen funds reportedAgreeDisagree
Cc9f267dcClaimReth's block-building software used vulnerable calculation code across networks built with Optimism's OP Stack, creating shared defect risks across multiple interconnected Ethereum layer-2 blockchainsAgreeDisagree
Cc9f267dcClaimIncorrect state-root calculations can cause blockchain nodes to disagree on block validity, potentially halting transaction processing or network synchronization across affected infrastructureAgreeDisagree
Cc9f267dcClaimGeorgios Konstantopoulos, chief technology officer at Paradigm, said a flaw in execution client Reth's legacy state-root calculation system could return incorrect cryptographic hashes when processing specific smart contract storage configurationsAgreeDisagree
Cc9f267dcClaimParadigm CTO Georgios Konstantopoulos clarified that Base and other OP Stack networks avoided faulty withdrawal risks because ecosystem bridge mechanisms rely on separate transaction receipts or multisignature authorizationAgreeDisagree
