Transaksi Off-Chain - Indodax Academy

Off-chain transactions refer to transactions that occur on crypto networks that move value outside the blockchain. Due to the zero/low fees, off-chain transactions are gaining popularity, especially among large participants. Off-chain transactions can be contrasted with on-chain transactions.

Off-chain transactions can be better understood when compared to on-chain transactions. On-chain transactions, simply called transactions, occur and are considered valid when the blockchain is modified to reflect transactions on the public ledger. It involves transactions being validated and authenticated by a suitable number of participants, recording transaction details in the appropriate blocks, and broadcasting the required information across the blockchain network, making it immutable.

Transactions of this kind can be undone only after most of the network’s hashing power has come to an agreement. Basically, every step associated with an on-chain transaction takes place on the blockchain, and the state of the blockchain is modified to reflect the occurrence and validity of the transaction.

Advantages of Off-chain Transactions

  1. Can be executed instantly. On-chain transactions, on the other hand, can have long lag times, depending on the network load and the number of transactions waiting in the queue to be confirmed.
  2. Off-chain transactions usually have no transaction fees, as nothing happens on the blockchain. Since there are no miners or participants required to validate transactions, there are no fees, making it an attractive option, especially if large amounts are involved. On-chain transactions, meanwhile, can sometimes incur high fees, leading to the issue of Bitcoin Dust, a situation where small amounts of bitcoin cannot be transacted due to high transaction fees.
  3. Off-chain transactions offer participants more security and anonymity as the details are not publicly broadcast. In the case of on-chain transactions, it is possible to partially determine the identity of the participant by studying the transaction pattern.
