Danksharding and proto-danksharding enhance Ethereum scaling by optimizing layer-2 communication with the main chain.
Danksharding and proto-danksharding are critical components in upgrading the Ethereum consensus layer. These technologies aim to enhance Ethereum’s scalability and efficiency, particularly in the context of layer-2 rollup solutions.
Danksharding is a layer-2 scaling solution designed to empower the world’s second most popular blockchain, Ethereum, to achieve its full potential. Proto-danksharding is an intermediate step in the danksharding roadmap. Proto-danksharding, approved as part of EIP-4844, has been officially incorporated into Ethereum improvement proposals within the Ethereum Cancun-Deneb upgrade.
