Vitalik Buterin Proposes Cross-rollup Scaling Solution

Ethereum’s co-founder Vitalik Buterin has come up with a proposal to link the different second layer scaling solutions so that they can ‘talk’ to each other to maintain defi composability and synergy. There are now numerous second layer protocols, Optimistic being the latest with it to launch soon. Despite their many differences, they’re all basically a smart contract based network which you enter by depositing to the smart contract, with that smart contract then keeping account of ownership changes of transactions within it without communicating with the wider ethereum network unless there’s an onchain settlement or transaction. The problem is that unless everyone is using the same smart contract second layer, then something like Synthetix can’t ‘talk’ to Uniswap and so Y strategies can’t work unless it’s all done on-chain. Still, any scaling is better than none. Thus most main dapps are launching some ‘isolated’ second layer smart contract which…
