When you make a cryptocurrency transaction, one of the most crucial steps is the confirmation process. 

This step plays a key role in determining the safety and finality of your transaction. 

When you send or receive cryptocurrency, the network must check and verify your transaction.

People call this process “confirmation.” It helps ensure that someone performs the transaction and that it is not fake.

Until the network confirms a transaction, it’s not fully complete, and the money remains unsafe.

Read on to find out more about what confirmation means, how it works, and why it’s a key part of keeping your cryptocurrency transactions safe.

What is Confirmation in Cryptocurrency?

In cryptocurrency, people use the term “confirmation” to describe the process of verifying that someone has added a transaction to the blockchain.

A confirmation occurs when the blockchain network accepts a new block that contains several transactions.

When a miner adds a new block to the blockchain, one “confirmation” has taken place.

This action verifies that all the transactions in that block are confirmed and now belong to the blockchain.

As miners add more blocks to the chain, your transaction receives more confirmations.

For instance, if miners add three more blocks after the block with your transaction, your transaction now has four confirmations. The more confirmations there are, the more secure the transaction becomes.

Why Do Confirmations Matter?

Confirmations play an important role by validating transactions and preventing them from being undone, which keeps the blockchain safe and trustworthy.

Without confirmations, a transaction lacks full security, and someone could potentially cancel or reverse it. Confirmations prevent people from attempting to spend the same cryptocurrency twice, a practice known as ‘double-spending.’ As a transaction receives more confirmations, it becomes increasingly secure.

Each cryptocurrency requires a specific number of confirmations for full acceptance.

Bitcoin transactions are usually safe after six confirmations, while Ethereum transactions often need around 30 confirmations to be secure.

How Do Confirmations Work?

When you send cryptocurrency, your transaction is grouped with other transactions into a “block.” This block then needs to be verified by miners or validators (depending on the type of cryptocurrency). 

Once verified, the block is added to the blockchain, and your transaction gets its first confirmation.

Each time a new block is added after your transaction, you get an additional confirmation. For example:

• 1 confirmation: Your transaction is in the blockchain but only just added.
• 3 confirmations: Three new blocks have been added after your transaction, making it more secure.
• 6 confirmations: Generally considered very safe, as six blocks have been added on top of your transaction.

How Many Confirmations Are Needed?

The number of confirmations needed depends on the cryptocurrency and the platform you are using. 

• Bitcoin (BTC): Usually requires 6.
• Ethereum (ETH): Typically considered secure after 30.
• Litecoin (LTC): Around 6.
• Dogecoin (DOGE): Requires 60.
• Bitcoin Cash (BCH): Needs 15.
• Monero (XMR): Requires 10.
• Polygon (MATIC): Needs 127.
• USDT (ERC-20): Typically secure after 14.
• USDT (TRC-20): Just 1 confirmation is required.

Some exchanges may require fewer or more confirmations, depending on their security policies.

How Long Do Crypto Confirmations Take?

The time it takes for a cryptocurrency confirmation depends on the specific blockchain network and its design.

Bitcoin confirmations generally take around 10 minutes per block. However, to ensure the transaction is fully secure, many services require 3 to 6 confirmations, which can take 30 minutes to an hour.

Ethereum confirmations are much faster, taking roughly 5 minutes per block. 

Similar to Bitcoin, the number of confirmations required for complete security varies, but 12 to 30 confirmations may take only a few minutes.

In short, the time varies depending on the network’s block time and the required number of confirmations.

How Do I Check My Crypto Confirmations?

To check your crypto transaction confirmations, you need to follow these simple steps:

1. When you make a transaction, you’ll receive a unique transaction ID (TXID). This ID can be found on your wallet or the exchange where you made the transaction.

2. Go to a blockchain explorer that matches the cryptocurrency you’re using like Bitcoin, Ethereum, Cardano Explorer.

3. Paste the transaction ID in the search bar of the blockchain explorer.

4. Check the confirmation status, the explorer will show the details of your transaction, including how many confirmations it has received so far. 

You can track this until your transaction has the required number of confirmations for it to be considered final.

What Affects Confirmation Time?

1. Network Congestion

When lots of transactions are waiting to be confirmed, it might take longer for them to be processed.

2. Transaction Fees

Transactions with higher fees are usually processed faster because miners prioritize them. Lower-fee transactions might take longer.

3. Type of Cryptocurrency

Some cryptocurrencies have faster block times than others. For example, Bitcoin takes around 10 minutes to create a new block, while Litecoin is faster, at about 2.5 minutes per block.

Conclusion

Confirmation is an essential part of how cryptocurrency transactions work. It verifies that a transaction is legitimate and secure, preventing issues like double-spending or fraud. 

The more confirmations a transaction has, the safer it becomes. 

When you trade Bitcoin, Ethereum, or any other cryptocurrency, understanding the confirmation process will increase your confidence in how the blockchain processes and secures your transactions.
