The interop overview discusses the possibility of using interop protocol to find bottlenecks in smart contract systems and horizontally scale them. Interop protocol can fundamentally change the developer experience for smart contract applications by providing an equivalent experience between end-end chains. The author believes that it will always be cheaper and simpler to do interop between two op stack chains than between an orbit or P stack chain. The Ethereum Community is supportive of low Laten interoperability between ecosystems, but it's unclear if incentives are set up for it to happen. Interoperability solutions that work between cross-r frameworks will be developed and tested to see which ones are cheaper and which ones will win. The bottleneck for scaling is vertical scaling, and it's going to be difficult to scale to the entire world no matter how much vertical scaling is done. The Interop overview aims to attack both vertical and horizontal scaling problems by implementing new standards for interop implementation and implementing new interoperability solutions. The article also discusses the need to avoid state filters and filters for state and state-of-the-table transactions, as well as the use of pre-distributed and distributed ledgers and blockchains. Additionally, the article discusses the importance of using pre-chain and pre-blockchain transactions to improve the scalability and scalability of the Ethereum network.
