ETHEREUM FINALIZES 'DENCUN' UPGRADE, IN LANDMARK MOVE TO REDUCE DATA FEES

Summary from the TLDR Crypto newsletter

Ethereum has activated the Dencun upgrade, which is expected to catalyze growth on L2 networks like Arbitrum and Polygon by reducing fees. The hard fork accomplished this through "proto-danksharding", adding a new place for data storage on the blockchain at a lower cost. The upgrade is expected to make transaction settlements more efficient and cheaper for rollup networks, which will in turn bring down fees for end users.
