In this article, you will learn what is confirmation meaning in blockchain. When you send cryptos from your wallet to another crypto wallet, you will have to wait for the assets to be put in the receiving wallet. The duration you wait for is for the confirmations before your transaction is validated.
What is Confirmation Meaning in Blockchain?
Confirmation on a cryptocurrency blockchain occurs when the transaction in question is included in a block that is added to the blockchain, and how long confirmations take depends on the coin, as each coin has a different time frame for how quickly blocks are mined.
Transactions on blockchains are not executed as soon as you make the request. You have to wait until the block is completed, locked, and added to the chain. Until then, your transaction is not considered immutable and can be reversed. However, even the Completion of just one block is not enough to ensure the permanence of a transaction.
Sometimes, when miners are racing against each other to break the cryptographic code, two or more miners reach the solution simultaneously. So, all of them are selected as validators for the time being, and each mines his or her own block. All these blocks are then added as extended branches of the most recent block.
The network then waits for the next few blocks. Once a certain number of blocks have been added, the length of each of the extended branch chains is observed. Only the chain with the longest length is kept, and the rest of the branch chains are discarded. All the transactions recorded in the discarded blocks are reversed, and users are returned their funds as if they were never transferred.
Users have to wait until more newly mined blocks are added next to the block containing their transaction records. Each attached block will be counted as one blockchain confirmation. The more confirmations a transaction has, the lesser its chances of being reversed, and the more secure it will be.
Apart from being immutable now, transactions with larger confirmation numbers are also safe from hacking attacks. This is because all blocks are connected in a chronological sequence. In this way, every block on the blockchain is essentially a succession to the one before it.
How Long Does a Blockchain Confirmation Take?
The time needed to add one confirmation to a transaction will vary from one blockchain to another. It entirely depends on how long the network takes to mine one block.
For example, in the case of Bitcoin, a new block is added every 10 minutes. So, in order to get ten confirmations on a transfer, you may have to wait almost one and a half hours. However, Ethereum and Solana, being proof of stake blockchains, take a lot less time to mine one block. That's why you need to wait only a few minutes to get as many as a few hundred confirmations.
Bottom Line
Blockchain confirmations are essential for securing your transactions. The best way of ensuring a faster confirmation is by paying a higher fee. If you are interested in cryptocurrencies, knowledge about what is confirmation meaning in blockchain is needed.
