Brief Overview of Ethereum Layer 2 Scaling Solutions: Rollup and Plasma Principles and Current Adoption

Finance is the scenario where blockchain is most easily implemented. Over the past year, we have seen various decentralized financial products in the Ethereum ecosystem, many bearing the shadow of traditional financial products, such as decentralized lending, trading, and derivatives. However, finance pursues efficiency, and Bitcoin's network processes 5 transactions per second, Ethereum 15 transactions per second, compared to Visa's average of 2,000 transactions and peak of tens of thousands, they seem like products from different eras. Blockchain's TPS (transactions per second) largely limits the adoption of blockchain, which in turn limits inclusive finance.
