The Ethereum blockchain had a major upgrade in early 2023. The “Dencun” project and its “proto-danksharding” feature are now being tested on a new network, getting closer to being used for real.
Proto-danksharding is meant to make transactions cheaper for layer-2 blockchains and to make data storage less expensive by creating a new space for data called “blobs. ” There are many layer-2 chains on top of Ethereum, so this upgrade is important for supporting their growth.
The Dencun upgrade on the Sepolia testnet happened on Thursday at 5:51 PM ET and finished at 23:10 UTC.
Sepolia is the second of three trials to test a computer simulation called Dencun. Earlier this month, Dencun started to work on the Goerli testnet, but it didn’t finish at first.
Next week, on February. 7, Dencun will start using its last test version on Ethereum, Holesky. Next, developers will choose a date to start using Dencun on the main blockchain.
Testnets are like copies of a main blockchain where developers can try out different changes to the protocol and its applications without risking anything.
Dencun, which was supposed to happen in late 2023, will be the biggest improvement for Ethereum since the Shapella upgrade last March, which allowed people to take out their staked ether (ETH).
