The last month has continued 2021's trend of sucking up yet more names into the cryptoverse, from Adidas to Discord and even the US constitution! Though some of these ended in failure, the drift towards web3 is inevitable. We also celebrated one year of the Beacon chain with a roadmap for Ethereum development (made up of blocks termed Merge, Surge, Verge, Purge and Splurge - fine rhythm work over at the Ethereum Foundation).

Over at Etherscan, we made long-awaited changes to the Transaction page: adding transaction navigation, tweaking the UI, and supporting Flashbots private transactions.
