Blockchain Layer 2 Rollups, Optimistic vs zero knowledge
Ohm Patel · INTERNATIONAL JOURNAL OF ADVANCED RESEARCH IN ENGINEERING & TECHNOLOGY · 2023
The current Layer 1 blockchain, such as Ethereum and Bitcoin, has several problems related to scalability and cost.Layer 1 blockchain networks have always been a struggle for Ethereum over scalability.Many of these factors can be attributed to the network's nature of linear processing of transactions.During high traffic, these networks get crowded, slow the transaction time, and charge high fees.For many industries, these have made blockchains unusable, even though previously, I described them as getting from bad to worse in terms of functionality.To tackle these issues, developers have a singular aim in mindto craft blockchain scaling solutions that improve efficiency, expand capacity, and bring down costs of transactions so that blockchains can deliver the high performance demanded of them to match today's digital world.Rollups have become one of the most promising innovations in satisfying the stated need.Rollups can be described as a particular class of blockchains whose primary function is to increase the transactional capacity.Rollups, in the case of blockchain, are 'layer 2' scaling solutions that improve the transaction rate of the blockchain network.Thus, "Rollups" accurately name what they dothey combine several transactions into batches outside the mainstream network before performing these operations as one transaction in the mainnet.
