Shared Sequencing: Defragmenting the L2 Rollup Ecosystem - HackMD # Shared Sequencing: Defragmenting the L2 Rollup Ecosystem As Ethereum has grown, its scalability worries have gone from theoretical to practical. Especially during periods of high network activity, many users have been priced out of sending transactions over the Ethereum blockchain. A solution to this problem is moving the execution of transactions off-chain through [rollups](https://joncharbonneau.substack.com/p/rollups-arent-real). At a high level, rollups outsource a L1 blockchain’s computation to a single party, which in tu
