Ethereum's Dencun Upgrade Reaches Final ‘Holesky’ Testnet, Starting Countdown to Data 'Blobs'
Summary
Ethereum's upcoming Dencun upgrade underwent its final dress rehearsal on the Holesky test network. The test simulated "proto-danksharding," a feature designed to reduce transaction costs for rollups and make data availability cheaper through the introduction of "blobs," a new space for data storage. The successful upgrade brings Dencun closer to activation on the mainnet blockchain, expected in the next few weeks. Holesky, the newest and largest of three testnets, was the last to simulate Dencun. Ethereum developers will meet to finalize a date for the mainnet Dencun upgrade, projected for late February or early March.
