Clients of the Starcoin Blockchain create transactions and submit them to a full node. Then the full node decides the order of transactions according to certain rules. A full node contains the following logical components:

Txpool

• Txpool is a buffer that holds the transactions that are “waiting” to be executed.
• When a new transaction is added to a node’s txpool, this node’s txpool shares this transaction with other nodes.

Consensus

• The consensus component is responsible for ordering blocks of transactions and agreeing on the results of execution by participating in the consensus protocol with other nodes in the network.

BlockChain

• BlockChain maintains the internal state of the chain, providing context for other components to function properly.

Executor

• The executor component utilizes the virtual machine (VM) to execute transactions.

Virtual Machine (VM)

• Txpool use the VM component to perform validation checks on transactions.
• VM is used to run the program included in a transaction and determine the results.

Miner

• Calculate hash by certain rules.

Storage

• The storage component is used to persist agreed upon blocks of transactions and their execution results.
