All of a sudden, 0. On the other hand, the engineers and developers realized that the diminishing block mining rewards will need to be compensated by transaction fees. Therefore, in order for Bitcoin to keep its security, a fee market must develop as a financial supplement for miners. Info: In a nutshell, Bitcoin fees went from preventing transaction spam to becoming an essential element of the mining profitability. And as the mining rewards get reduced in half every four years, fees will become even more important in the economic game theory of the network.

Most modern wallets enable you to set the Bitcoin fee in a simple and comprehensive way. For convenience and ease of use, lots of them opt in for a priority system: you can either opt for a high fee in order to get a confirmation in the next block, or you can pay less and potentially delay the process.

However, the more technical and lesser newbie-friendly presentation makes it more fitting for users who are well-versed with the mechanisms of the Bitcoin network. After you check either of these resources to make sure that your transaction will not get stuck in the mempool, you are ready to manually set your Bitcoin fees. On the other hand, if you simply want to use a system of priority and estimation, you can also rely on the tools that developers have added to remove the requirement for technical understanding.

For instance, Bitcoin Core the free and open-source desktop wallet that runs a full Bitcoin node offers multiple options for time preference. This means that you can bump the fee after your transaction gets broadcast and registered in the mempool, so that it becomes a priority for miners.

Wasabi Wallet takes the design of selecting the fee to the next level of elegance with a bar that you simply drag from left to right in order to choose when you want your transaction to be delivered and how much you want to pay in USD. The CoinJoin-friendly desktop wallet chooses the most intuitive way of allowing the user to determine costs, and the implementation is worthy of praise. Blockstream Green is one of the friendliest yet feature-packed wallets on the market.

The Blockstream Green design for determining fees is based on three presets that highlight time preference: fast for confirmation within 30 minutes , medium the default setting, which should confirm within 2 hours , and slow whose lower cost will bring the first confirmation in about four hours. The system is popular among mobile wallet developers, as it appeals to newbies and gets the job done without causing confusion. Things to Consider with Fee Estimators These are the estimated fees you should use depending on how fast you would like to obtain the first confirmation for a typical transaction.

The transaction fee you pay will only affect the time you have to wait until the first confirmation. When making a Bitcoin transaction, recipients usually require somewhere between 2 and 6 confirmations to consider the transaction as valid. Once your transaction is included in a Bitcoin block and thus obtains the first confirmation, you will need to wait approximately 10 minutes for each additional confirmation.

After the first confirmation, the waiting time for each additional confirmation is completely independent of the transaction fee you paid. Because of the decentralized nature of the Bitcoin network and the fact that there is sometimes congestion in the available block space because of the 1 MB limit , the amounts shown here are probabilistic and there are no guarantees that they will work.

To calculate the feerate for your transaction, take the fee the transaction pays and divide that by the size of the transaction currently based on weight units or vbytes but no longer based on bytes. For example, if a transaction pays a fee of 2, nanobitcoins and is vbytes in size, its feerate is 2, divided by , which is 10 nanobitcoins per vbyte this happens to be the minimum fee Bitcoin Core Wallet will pay by default. When comparing to the feerate between several transactions, ensure that the units used for all of the measurements are the same.

For example, some tools calculate size in weight units and others use vbytes; some tools also display fees in a variety of denominations. Bitcoin transactions can depend on the inclusion of other transactions in the same block, which complicates the feerate-based transaction selection described above. This section describes the rules of that dependency system, how miners can maximize revenue while managing those dependencies, and how bitcoin spenders can use the dependency system to effectively increase the feerate of unconfirmed transactions.

Each transaction in a block has a sequential order, one transaction after another. Each block in the block chain also has a sequential order, one block after another. For example, if Alice pays Bob in transaction A and Bob uses those same bitcoins to pay Charlie in transaction B, transaction A must appear earlier in the sequence of transactions than transaction B. Often this is easy to accomplish because transaction A appears in an earlier block than transaction B:. But if transaction A and B both appear in the same block, the rule still applies: transaction A must appear earlier in the block than transaction B.

This complicates the task of maximizing fee revenue for miners. Normally, miners would prefer to simply sort transactions by feerate as described in the feerate section above. But if both transaction A and B are unconfirmed, the miner cannot include B earlier in the block than A even if B pays a higher feerate.

This can make sorting by feerate alone less profitable than expected, so a more complex algorithm is needed. For example, consider the following four transactions that are similar to those analyzed in the preceding feerate section:. To maximize revenue, miners need a way to compare groups of related transactions to each other as well as to individual transactions that have no unconfirmed dependencies.

To do that, every transaction available for inclusion in the next block has its feerate calculated for it and all of its unconfirmed ancestors. In the example, this means that transaction B is now considered as a combination of transaction B plus transaction A:. These transaction groups are then sorted in feerate order as described in the previous feerate section:. Any individual transaction that appears twice or more in the sorted list has its redundant copies removed.

Finally, we see if we can squeeze in some smaller transactions into the end of the block to avoid wasting space as described in the previous feerate section. Except for some edge cases that are rare and rarely have a significant impact on revenue, this simple and efficient transaction sorting algorithm maximizes miner feerate revenue after factoring in transaction dependencies.

Note: to ensure the algorithm runs quickly, implementations such as Bitcoin Core limit the maximum number of related transactions that will be collected together for consideration as one group. As of Bitcoin Core 0. Wallets that explicitly support this feature often call it child pays for parent CPFP because the child transaction B helps pay for the parent transaction A.

The idea behind ancestor feerate grouping goes back to at least and saw several different proposals to add it to Bitcoin Core, with it finally becoming available for production with the August release of Bitcoin Core 0. The following sections describe the behavior of the reference implementation as of version 0. Earlier versions treated fees differently, as do other popular implementations including possible later versions.

By default, Bitcoin Core will use floating fees. Sometimes, it is not possible to give good estimates, or an estimate at all. Furthermore, Bitcoin Core will never create transactions smaller than the current minimum relay fee.

This section describes how the reference implementation selects which transactions to put into new blocks, with default settings. All of the settings may be changed if a miner wants to create larger or smaller blocks containing more or fewer free transactions.

Then transactions that pay a fee of at least 0. For Bitcoin Core 0. Transactions are added highest-priority-first to this section of the block. However, the rule that all outputs must be 0. To prevent "penny-flooding" denial-of-service attacks on the network, the reference implementation caps the number of free transactions it will relay to other nodes to by default 15 thousand bytes per minute.

As of May , the following sites seem to plot the required fee, in satoshi per kilo byte, required to get a transaction mined in a certain number of blocks. Note that all these algorithms work in terms of probabilities. Historically it was not required to include a fee for every transaction.

A large portion of miners would mine transactions with no fee given that they had enough "priority". Today, low priority is mostly used as an indicator for spam transactions and almost all miners expect every transaction to include a fee. ASIC mining hardware keeps Bitcoin secure through proof of work. The block reward started at 50 bitcoins per block.

Currently, it is 25 bitcoins per block. In July it will drop to Mining fees are paid each time a user sends a transaction on the network. In the example below, a user sent 0. Fees incentivize miners to include transactions in a block. Once a transaction has been included in a block it is confirmed. Unconfirmed transactions sit in something called the mempool until they are confirmed.

Transactions sent with low fees may get stuck in the mempool. Posts about stuck transactions like the one below are published many times per day on Bitcoin message boards. Transactions sent with proper fee amounts are confirmed in about 10 minutes. The miner or mining pool that includes a transaction in a block collects the transaction fee. In the example above, Antpool mined block This block included transactions with a total of 0.
