5 Things You Need to Know About “Irreversible” in Blockchain

Jakarta, Pintu News – Irreversibility is the nature of blockchain transactions that makes them secure, transparent, and final, but it also brings great responsibility on users. Understanding this nature is an important step to avoid mistakes and losses in the crypto world.

1. Irreversible means what?

In the context of blockchain, irreversible means that a confirmed transaction cannot be reversed, changed, or deleted from the network. Once data is entered into a block and validated by the network, the transaction becomes permanent and is stored forever in the digitalledger.

This term differs from the traditional banking system which still allows for cancellation or chargeback under certain conditions.

2. Irreversible Scenario Example

• Bitcoin (BTC) transactions: After 6 confirmations on the network, the transaction is considered final and cannot be reversed.
• Transfer Ethereum (ETH) to the wrong address: Funds will be permanently lost if the recipient is unwilling or unable to return them.
• Purchase of NFTs on an on-chain marketplace: Once the payment is processed and the NFT changes hands, this process cannot be reversed except through the voluntary agreement of the recipient.

3. Pros of Irreversible System

• Security & Trust: Avoid fraud such as double spending.
• Transaction Finality: Ensure every transaction is valid and complete without the risk of being canceled unilaterally.
• Transparency: All transactions are permanently recorded on the blockchain and can be publicly verified.

4. Irreversible Drawbacks or Risks

• There is no turning back: Incorrect address or quantity cannot be corrected.
• Risk of Fraud: If funds are sent to scammers, the chances of recovery are almost zero.
• Full Responsibility on the User: No third party can cancel a transaction for you.

5. Safe Ways to Deal with Irreversibility

• Check the Destination Address: Use copy-paste and verify the start-end characters of the address.
• Use Small Amounts to Test: Send a minimal amount first before a large transfer.
• Use a Trusted Platform: Official exchanges like Pintu, Indodax, or Binance have extra security procedures before transactions.
• Enable Layered Confirmation: Utilize two-factor authentication (2FA) and email/SMS verification before sending funds.
