Blockchain infrastructure company Blocknative has released a new tool called ethernow.xyz, which examines the "mempool" of pending transactions on Ethereum. The tool is designed to help reduce instances of block-level manipulation and protect users from front-running bots. It is also intended to help researchers understand why certain transactions fail or succeed, and how they are added to certain blocks. The tool was made possible through a grant from the Ethereum Foundation and was presented at the Columbia CryptoEconomics Workshop in New York. Blocknative underwent a restructuring in October, resulting in a reduction of a third of its headcount.
