Frequently Asked Questions
What is a blockchain transaction?
A transaction is a transfer of value or data on a blockchain. It includes inputs (where the value comes from), outputs (where it goes), and a digital signature proving ownership.
What is the mempool?
The mempool (memory pool) is a holding area for unconfirmed transactions. Miners and validators select transactions from the mempool to include in the next block, usually prioritizing higher fees.
Why do transactions have fees?
Transaction fees compensate miners or validators for their work and prevent network spam. Fees are typically calculated based on transaction size and network congestion.
What is a confirmation?
A confirmation occurs when a block containing your transaction is added to the blockchain. Each subsequent block adds another confirmation, making the transaction more secure.
