A typical IOTA transaction

Fig. 15: Overview of an IOTA transaction. Image: © WZL | Anton Shirobokov
- hash: string: 81-trytes unique transaction (tx) hash
- message: string: 2187-trytes signature message. If values are spend, the message contains the signature of the private key. If no values are spend, either the message is empty or contains a arbitrary input
- address: string: 81-trytes address, either of the recipient or the sender
- value: integer: tx value in iota
- timestamp: integer: time and date of the tx
- currentIndex: integer: the index of this tx in the bundle
- lastIndex: integer: the total number of tx in the bundle
- bundle: string: 81-trytes bundle hash to group bundle's tx
- trunk: string: 81-trytes hash of the first tx that was approved with this tx
- branch: string: 81-trytes hash of the second tx that was approved with this tx
- nonce: string: 81-trytes hash. The nonce is required for the tx to be accepted by the network. It is generated by doing PoW.
