Scaling Ethereum ( $2,415.12 ) Beyond the Merge: Danksharding

Compared to sidechains, Layer 2 rollups are considered by many developers to be the more secure way for Ethereum ( $2,415.12 ) to scale. Rollups, like sidechains, take the stress off of Ethereum ( $2,415.12 ) by executing transactions on a separate blockchain. Transactions are “settled” on the rollup chain, bundled up, and then “posted” to Ethereum ( $2,415.12 ) . Unlike sidechains, rollups borrow their security from the Ethereum ( $2,415.12 ) mainnet – they use fancy cryptography and other methods (like a multi-day dispute period) to allow Ethereum ( $2,415.12 ) mainnet nodes to confirm that transactions are legitimate.
