Oct 10, · One confirmation usually takes up to 10 minutes.

Dec 03, · Once that block is created and the new transaction is verified and included in that block, the transaction will have one confirmation. Approximately every ten minutes thereafter, a new block is created and the transaction is reconfirmed by the Bitcoin network.

Ethereum is working to scale quickly to take on more users, and through Proof of Stake, confirmations should be even quicker. There are multiple methods for speeding up your transaction and deciding on the best gas price when sending your Ethereum transaction. You can try ETH Gas Station to see an overview of gas usage, and you can see how many transactions are pending by using Etherscan. Etherscan is particularly popular since you can order transactions by gas price simply click on the GasPrice column.
Blockchain confirmations are essential for securing your transactions. The best way of ensuring a faster confirmation is by paying a higher fee. As all blockchains begin scaling up to prepare for even more users, it will be interesting to see how that affects the prices we pay and the times we wait.

See our guide on Bitcoin Mining. Moreover, miners are bound to act in a way that incentivizes them the most and in case of mining these miners prefer to take those transactions first that have more transaction fees attached to it.
Miners receive I know you are thinking, how block mining fee is related to your transaction not getting picked from the mempool? Block is merely a collection of transactions, and each transaction has a transaction fee attached to it. Hence it makes economic sense for the miners to pick up those transactions first from the mempool which has higher fees attached to it. And miners are quite proactive in this, as all the miners keep their mempool in descending order of transaction fees bitcoin mempool fees attached to it.
But as we know that a Bitcoin confirmation will minimum take 10 minutes and hence for six confirmations one needs to wait atleast 60 minutes provided the transaction is included in the very next block. But this is an ideal scenario that is often different from reality because there are enough chances that your transaction will not be included in the very next block.
Also, these confirmations are nothing but the number of blocks added after your transaction is included on the chain and first confirmation means your transaction is included in the most recent block mined.
Yes, of course, there are some Bitcoin transaction time estimators that you can use, but they all rely on the Bitcoin transaction fees you have attached to that particular transaction.
So this way you can easily calculate your approximate Bitcoin confirmation time and know exactly how long does Bitcoin takes to transfer? In addition to this you can also use Block explorer to check your transaction confirmations. All you need to do is enter your wallet address or the transaction ID which looks something like this:.
The average block time of Bitcoin is 10 minutes. But not all transactions are confirmed in 10 minutes. It could take hours or it could even take a day to get 1 confirmation and it depends on few factors.
In Bitcoin all transactions are processed only through miners and due to this transactions are subject to delays. Two reasons that causes delay in transaction are network congestion and low transaction fees. Miners prioritize transactions that pays higher fees. If your transaction is taking a long time to get 1 confirmation then you might have not included a reasonable transaction fees.
To learn more transaction fees and time we suggest you read this topic on Mempool. Actually you can spend the output of transaction that has 0 confirmations. Zero confirmation is nothing but a transaction that is not yet part of the blockchain. The transaction that has 1 confirmation means it is accepted by the blockchain.
If you are receiving a payment from a trusted party you can accept their transaction even if it has 0 confirmations unconfirmed. If you are a merchant accepting Bitcoin then for small payments 1 confirmation is enough. But remember that a transaction that has 0 and 1 confirmations can be easily reversed. Zero confirmation transactions are more prone to Race attack and Finney attack.
With 0 and 1 confirmation double spending double-spend attack is possible. Double spending is a practice in which an user attempts to spend same money more than ones. This is why majority of exchanges require 2 to 3 confirmations. But the industry standard is 6 confirmations which takes approximately 1 hour and it is considered safe and secure. So why 6 confirmations? Bitcoin transactions are recorded in a distributed ledger.
There is no central authority to consult whether if a transaction is successful or not. Since the system is decentralized the community considers transaction confirmation numbers as a validity. There is nothing special about 6 confirmations.
This number is chosen assuming that it would cost an attacker more in order to double spend. With 6 confirmations it becomes practically impossible for an attacker to reverse a transaction, create an alternate chain faster than the original chain.
