+OVM sources compute from decentralized and verifiable providers, known as Open Nodes, ensuring high-performance execution for intensive workloads.
 
 ### Interoperability
 
 OVM is EVM-compatible, which means that it supports native execution of Solidity smart contracts.
 
 In fact, it interoperates with any blockchains, EVM or not.
