# Decentralization **Decentralization is at the heart of Trac Network** * Transaction settlement and smart contract execution are separated: * Transactions are performed by the Main Settlement Bus (MSB). * MSB validators accept transaction requests and sign those. * Smart Contract operations are performed by individual nodes in the network (the apps). * Consensus is separated between MSB and apps. * Apps represent their own network and use their own consensus to settle smart contract operations. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
