A transaction pool is a collection of unconfirmed transactions waiting to be added to the blockchain. When users initiate a transaction, it is broadcast to the network and enters the transaction pool until a miner or validator includes it in a new block.Transactions in the pool are prioritized based on various factors, most commonly the transaction fee paid by the sender. Higher fees generally incentivize miners to select those transactions first. This system helps manage the flow of transactions, especially during periods of high demand.Miners regularly check the transaction pool to gather pending transactions they want to include in the next block they create. Once a transaction is confirmed by being added to a block, it is removed from the pool. The transaction pool plays a critical role in maintaining network efficiency and ensuring that transactions are processed in a timely manner. It helps prevent network congestion and helps maintain a balanced load on the system.
