Bitcoin Average Confirmation Time is at a current level of , down from yesterday and down from one year ago. This is a change of %. A Bitcoin user can't reverse a Bitcoin transaction after confirmation. However, they can cancel a transaction if unconfirmed. A confirmation is when a transaction makes its way from the transaction pool in to the blockchain. Or in other words, it's when a bitcoin transaction. HOE BETALEN MET BITCOINS DEFINITION

A Bitcoin transaction, or any cryptocurrency transaction must be confirmed on a blockchain to verify that the transaction is legitimate. A confirmed transaction means that the transaction has been included in a block, and therefore included in the blockchain.

That means the transaction has now been officially recorded and verified, the payment can now be processed, and it can no longer be reversed. Only you have access to this key, and the key is automatically generated and unique for each transaction. Once it has been solved by a miner, the miner adds it to their own version of the blockchain ledger. By being added as part of a block to the blockchain, your transaction is now confirmed.

Each block in the blockchain is mathematically connected to the block that came before it. After the block containing your transaction is added to the chain, any block that follows acts as further confirmation. So, each block that follows the first confirmation is another confirmation that your transaction is legitimate.

Bitcoin blocks, containing all the most recent transactions, are added to the blockchain every 10 minutes. That means in theory, your transaction will receive its first confirmation within 10 minutes of the request being sent. The number of confirmations needed for a crypto transaction to be processed will depend on the exchange, and sometimes depend on the amount being transferred.

Some exchanges will process a transaction after just one confirmation, many require three confirmations, while some may require up to six.

The transactions that were included in those blocks are discarded and eventually go back to the transaction pool and are considered for inclusion in a later block.

When a fork occurs, it is uncertain as to which branch will be permanently kept in the blockchain and which branch es will be discarded. Therefore, the inclusion of a transaction in a block is insufficient to declare it as confirmed or durable in terms of ACID properties. How can we ensure that a transaction is permanently included in a block? While the immutability of a blockchain using Nakamoto consensus is probabilistic, the probability rapidly increases as the chain of blocks grow please refer to Bitcoin whitepaper for proof.

Therefore, once a transaction is included in a block, we could wait for subsequent blocks to be built along the same chain of blocks. If the chain of blocks containing the block with our transaction grows sufficiently long, it is safe to assume that the transaction is included in the longest chain with very high probability. Therefore, we could adopt a strategy where we wait for a certain number of blocks x to be generated after the transaction is included in a block. After x blocks, we can consider the transaction to be committed and thus perceived as immutable.

In case the block containing the transaction is no longer in the longest chain while we wait for x blocks, the process needs to restart.

Some mining enterprises may hide their hash power across several mining pools. Also mining ASICs can be temporarily overclocked to increase their hash power. This is less power-efficient but could be used for a brief burst of hashrate. See also: Irreversible Transactions. Each additional confirmation is a new block being found and added to the end of the blockchain.

Miners create blocks by solving the proof of work for their proposed block. The block interval has an average of 10 minutes but not every block interval is exactly 10 minutes. It follows a statistical process known as a poisson process , where random events happen with the same probability in each time interval.

Another way of expressing this is that the mining process has no memory, at every second a block has the same chance of being found. Poisson processes are well-understood but can be unintuative. There are lots of block intervals with a time less than 10 minutes but then a few block intervals much longer which bump up the average to 10 minutes. So the bitcoin network can get unlucky and a block won't be found for a whole hour. So approximately two-thirds of the time a block will be found in 10 minutes or less.
