Confirmations

Definition

A cryptocurrency transaction is considered confirmed when it is included in a block on the blockchain. Each new block after the first one is an additional confirmation for that transaction.

In the world of web3, confirmation refers to verifying and finalizing a transaction on a blockchain network. It’s like getting a thumbs-up from the network that your transaction has been processed and is now part of the permanent record.

Here’s a breakdown of what happens during a confirmation:

  • Transaction initiation: You initiate a transaction, such as sending tokens or deploying a smart contract.
  • Broadcasting: The transaction is broadcast to the network of nodes responsible for validating transactions.
  • Mining/verification: Miners or validators work to verify the transaction’s validity and ensure it complies with the network’s rules.
  • Adding to block: Once verified, the transaction is included in a block of transactions.
  • Confirmation: As additional blocks are added on top of the block containing your transaction, the number of confirmations increases.

Generally, the more confirmations a transaction has, the more secure and final it is. This is because it becomes increasingly difficult to reverse or tamper with a transaction once it has been buried under many subsequent blocks.

Your next trade takes three taps.
