Layer2 scaling solutions refer to the middle layer network built on Ethereum, aiming to improve the performance of Ethereum by increasing its TPS and reducing the gas fee.
The Ethereum community realized the importance of scalability three years, and successively came upw ith solutions such as state channels, side chains, and Plasma.
However, Rollup solution is most respected by Ethereum founder Vitalik Buterin, which is considered to have combined the advantages of solutions such as state channels, side chains, and Plasma.Optimistic Rollup, zk Rollup, ZKSync, StarkWare, etc. are often mentioned by Vitalik.
The Rollup solution also attracted the attention of institutions. Optimistic Rollup received $28.5 million investment from institutions such as A16Z and Paradigm. StarkWare received $76 million from Coinbase Ventures, Multicoin Capital, Bitmain, Intel, Sequoia Capital, Paradigm, and Vitalik himself.
The Optimistic Rollup mainnet will be launched in March. Recently, Arbitrum Rollup financing information is circulating, but the target amount is hard to reach.
Except the Optimistic Rollup and Arbitrum Rollup, what are the other solutions for Ethereum Layer 2? And which projects have annouced to support these solutions?
