Transaction Pool

Options and methods for configuring and monitoring the transaction pool include:

Dropping Transactions when Transaction Pool Full

Once full, the Pantheon transaction pool accepts and retains local transactions in preference to remote transactions. If the transaction pool is full of local transactions, the oldest local transactions are dropped first. That is, a full transaction pool continues to accept new local transactions by first dropping remote transactions and then by dropping the oldest local transactions.

Replacing Transactions with Same Nonce

If a transaction is received with the same sender and nonce as a pending transaction but a higher gas price, the pending transaction is replaced by the new one with the higher gas price.

Size of Transaction Pool

Decreasing the maximum size of the transaction pool reduces memory use. If the network is busy and there is a backlog of transactions, increasing the size of the transaction pool reduces the risk of transactions being removed from the transaction pool.
