Optimistic Rollups
Optimistic Rollups are a Layer 2 scaling solution that is gaining popularity in the blockchain space. They are being adopted by projects such as Optimism and Arbitrum. One of the key features of Optimistic Rollups is that they are EVM Compatible, meaning that they are compatible with the Ethereum Virtual Machine. This allows developers to easily port their existing Ethereum smart contracts to Optimistic Rollups without much modification. In terms of the underlying technology, Optimistic Rollups utilize a Plasma-like construction, which combines the benefits of both Optimistic Proofs of Use (OPU) and Zero-Knowledge Rollups (ZkR). This combination allows for efficient and secure transaction processing on the Layer 2 network.
Overall, Optimistic Rollups offer a promising solution for scaling Ethereum and improving its scalability and throughput. With their EVM compatibility and adoption by projects like Optimism and Arbitrum, they are poised to play a significant role in the future of blockchain technology.
