Ethereum's Major Upgrade Draws Closer with Successful Testnet Implementation
The most notable update to the Ethereum$2,315 -2.42% blockchain since early 2023 has successfully launched on the second of three test networks. This brings the highly-anticipated Dencun project, along with its pioneering feature - proto-danksharding, a step nearer to realization.
Proto-danksharding's Impact on L2 Blockchains
Proto-danksharding has been engineered to decrease the transaction costs for layer-2 blockchains, while also making data availability more cost-effective. This is achieved by introducing a novel compartmentalized space for data referred to as blobs. As the number of Layer-2 chains built on Ethereum is rapidly increasing, this update is recognized as a crucial part of the ecosystem's plan to support this growth.
Dencun's Rollout on Testnets
The Dencun upgrade was implemented on the Sepolia testnet on Thursday at 22:51 UTC (5:51PM ET) and concluded at 23:10 UTC. Sepolia is the second of three testnets to simulate the Dencun upgrade.
Earlier this month, Dencun was initiated on the Goerli testnet, but initially failed to finalize. The next phase will occur on Feb. 7, when Dencun will be launched on its last Ethereum testnet, Holesky. Upon successful completion, the developers will determine a date to activate Dencun on the main blockchain.
Low-stakes Environment for Protocol Changes
Testnets mimic a main blockchain, providing developers with an environment to make adjustments to the protocol or its decentralized applications without high risks.
Dencun Upgrade: A Significant Milestone for Ethereum
Originally scheduled for the last quarter of 2023, the Dencun upgrade will represent the most significant improvement to Ethereum since the Shapella update in March of the same year. The latter update enabled the withdrawals of staked ether (ETH).
