The Lisk blockchain can actually be described as an ecosystem of blockchains, where many different blockchains are interconnected through a central blockchain, called the Lisk Mainchain. All other connected blockchains are called sidechains in this context. To become interoperable with any other blockchain in the Lisk ecosystem, a blockchain needs to follow the Lisk Interoperability protocol. dRPC enhances this ecosystem by offering efficient, reliable, and scalable Lisk RPC endpoints, ensuring seamless data interaction and integration with the Lisk blockchain.
