Confirmations & Transaction Speed

Most of the API responses for blocks and transactions also return the number of confirmations. This is the number of blocks that are ontop of the block that contains your transaction. The number of confirmation required to be confident in the chain depends on whether the transaction was send via FAST transaction or SLOW transaction.

SLOW transactions are included in the block that the miners mine and will take approximately 2 minutes to be mined. FAST transactions are send instantly as a new FAST block is minted every 2 seconds on demand. Therefore for FAST transactions confirmations are not applicable because FAST transactions are written into FAST blocks which are guaranteed to be written into the chain.

When sending transactions it's recommended to use FAST transactions.

  • Confirmations for SLOW transacations: 7

  • Confirmations for FAST transactions: 0
