What does the file system of a Peer Node contain?

The file system of a Peer Node contains smart contracts and chaincode. In a blockchain network, Peer Nodes play a critical role by executing transactions and maintaining the ledger. Smart contracts are programs that automatically execute, control, or document legally relevant events and actions according to the terms of a contract or an agreement. Chaincode is a specific type of smart contract in Hyperledger Fabric, which is required for managing the state of the blockchain.

Having smart contracts and chaincode stored on the Peer Node allows the node to execute business logic defined in these contracts when transactions are invoked. This capability is essential for maintaining the integrity and functionality of the blockchain by ensuring that all nodes can execute the same transactions in a consistent manner.

While user credentials, raw transaction data, and network configuration files may be part of the larger ecosystem of a blockchain network, they are not a primary component of the file system specifically for Peer Nodes. User credentials are typically managed separately for access control, raw transaction data is handled within the blockchain ledger itself, and network configuration files are usually part of the setup and deployment process but do not reside at the core of a Peer Node's operation.
