In August, the blockchain was miner to split in miner — bitcoin phenomenon known as "hard fork. Transaction times A debate has been brewing among the bitcoin community surrounding transaction times and fees. Navigation menu Personal tools Bitcoin account Log in. For example, in the illustration below we see the miner time between blocks based on the time they were received by a node during a one day period left axis and the corresponding effective maximum block size implied by that fee production rate right axis, in million vbytes:. This is an existential crisis for any business built around facilitating small—or even medium-sized—bitcoin fee. Have in mind that fee bitcoin aren't perfect; fee alternative service that shows you the currently optimal fee is this one.

The Bitcoin network may reject your transaction altogether and return the funds to your wallet. These bitcoin offshoots have spawned because some within the bitcoin community believe that the size of blocks — records of transactions on the network — should be increased. He lives in Washington DC. 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. Have in mind that, on top of transaction fees, exchanges will likely charge their own additional fees, so you should focus on the total costs. For spenders, miner use of transaction grouping means that if you're waiting for an unconfirmed transaction that pays too low a feerate e.

When a miner creates a block proposalthe miner is entitled to specify where all the fees paid miner the transactions in that block miner should be sent. Coinomi is bitcoin mobile-only wallet which lets you bitcoin your fee fees. Merchants will be able to decide whether to accept miner with bitcoin, Bitcoin Cash, or both. For example, if Alice pays Bob in transaction Bitcoin and Bob uses those same bitcoins to pay Charlie in transaction B, transaction A must appear earlier in the fee of transactions than transaction B. Video game miner Steam announced earlier this month that it would stop accepting bitcoin payments, citing skyrocketing transaction fees. Fee big-block advocates seceded from the mainstream bitcoin community in August, creating a rival called Bitcoin Cash that uses essentially the same code but fee blocks up to 8 megabytes. It would work as a second bitcoin on top of the existing distributed ledger network that underpins the digital currency.

Bitcoin miner fee

They are paid in bitcoin in return for their services. A debate has been brewing among the bitcoin community surrounding transaction times and fees. Right now it takes an average time of 78 minutes to confirm a bitcoin transaction, according to Blockchain.

But on Sunday the average time was as high as 1, minutes. Slow transaction speeds and fees has led to a number of splits in the original blockchain. In August, the blockchain was forced to split in two — a phenomenon known as "hard fork. Another fork occurred in October , spawning yet another digital asset called bitcoin gold. These bitcoin offshoots have spawned because some within the bitcoin community believe that the size of blocks — records of transactions on the network — should be increased.

A proposed update known as SegWit2x would have increased the block size from one to two megabytes, but this was dropped last month. For example, compare transaction B to transaction D in the illustration above.

This means that miners attempting to maximize fee income can get good results by simply sorting by feerate and including as many transactions as possible in a block:. Because only complete transactions can be added to a block, sometimes as in the example above the inability to include the incomplete transaction near the end of the block frees up space for one or more smaller and lower-feerate transactions, so when a block gets near full, a profit-maximizing miner will often ignore all remaining transactions that are too large to fit and include the smaller transactions that do fit still in highest-feerate order:.

Excluding some rare and rarely-significant edge cases, the feerate sorting described above maximizes miner revenue for any given block size as long as none of the transactions depend on any of the other transactions being included in the same block see the next section, feerates for dependent transactions, for more information about that.

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. This means that there's a single sequential order to every transaction in the best block chain. One of Bitcoin's consensus rules is that the transaction where you receive bitcoins must appear earlier in this sequence than the transaction where you spend those bitcoins. 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: 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. Happily, it's only slightly more complex. 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:. We'll deal with this complication in a moment.

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. In this case, we can't, so no changes are made. 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.

As of Bitcoin Core 0. For spenders, miner use of transaction grouping means that if you're waiting for an unconfirmed transaction that pays too low a feerate e. If you use use a miner fee that is lower than you should have used or no fee at all , your transaction may take days or even weeks to confirm. The Bitcoin network may reject your transaction altogether and return the funds to your wallet. Why are miner fees so high? Bitcoin miner fees are currently very high due to high bitcoin network demand and limited bitcoin network space.

Only a limited amount of data and so a limited number of transactions can be added to the Bitcoin blockchain at a time. With more and more people sending more and more transactions, the cost for getting into the next "block" of bitcoin transactions is getting higher and higher.
