Cardano bug reportedly allows nodes to illegally manipulate transaction orders
Stake pool operators (SPOs) in Cardano (ADA), according to the co-founder of Adahandle and the operator of Blade Pool, one of SundaeSwap’s Scoopers, may potentially circumvent transaction ordering in the blockchain’s Mempool and thus prioritize certain transactions.As a response to a tweet that was posted on October 16 by $conread, who claimed that he had tested and proven that SPOs could.
Cardano is built on a transaction processing architecture in which transactions may be processed based on the fees the sender is prepared to pay. On Cardano, a user creates a transaction on their Cardano client software, which is then disseminated to all other nodes and forms part of the blockchain. This reportedly is a vulnerability, making it a potential attack vector that causes price manipulation. Apparently, this could be used to deny someone financial access because of a blacklisted AdaHandle, according to $conrad.
