When a new block arrives, it counts the number of transactions in each bucket and the total amount of fee rate paid in each bucket. Then it calculates how many blocks Y it took each transaction to be mined and tracks an array of counters in each bucket for how long it to took transactions to get confirmed and increments all the counters from Y up to the highest bucket. This methodology prevents the fee estimates from being skewed by several potential problems:. For example:. This had ripple effects:.
If a fee estimate algorithm fails to correctly predict the future state of the fee market then transactions can get stuck. Another method for correcting low-fee transactions is to use Child Pays For Parent, where you add much larger fees to new transactions that spend outputs of your stuck low-fee transactions. This incentivizes miners to prioritize confirming the entire set of your transactions.
Improvements can be made that incorporate forward-looking data by examining unconfirmed transactions in the mempool. By using mempool data you can bump up fees during times that the mempool grows in size and pull down fees during times that the mempool is nearly empty.
Services that create bitcoin transactions should also set minimum fee thresholds and maximum fee sanity checks, preferably dynamically. If you set a static maximum fee threshold and it becomes obsolete, you may find yourself in an emergency situation where you or your users have to upgrade software because it suddenly becomes impossible to create transactions. The fee market can be volatile, but over longer time periods it tends to spike and settle in a somewhat predictable range while remaining in an upward channel.
At time of writing, low fee transactions paying under 50 satoshis per byte can usually get confirmed over the weekend, though we have noted that as of March sometimes there is no weekend slack. They have been chosen to be as conservative and useful for the average user as possible.
But just as many people use Bitcoin for many different things, so do different users have different needs in terms of confirmation times. As this article was being written, Bitcoin Core contributor Alex Morcos released code to overhaul the fee estimate algorithm and additionally expose more tunable options via new RPC calls!
There is one common use case that receives little to no discussion: finding the minimum viable fee for the lowest priority sends. This becomes important for enterprise wallets that receive high volumes of low value outputs. Eventually they have to consolidate these outputs so that they can spend the value in regular transactions. You can view our 1, block target estimate here.
Bitcoin Average Transaction Fee
At BitGo our goal is to underbid median fee rates and overperform transaction confirmation times. Because transaction fee rates have continued to rise dramatically in , I spent some time in April working overhauling our fee estimate system once again. Running our internal metrics again, this time against a Monday in May:. Thus it looks like our new estimates are saving a bit less money but resulting in much better time-to-confirm performance.
However, the rest of the wallets in the ecosystem have since developed and improved upon their own fee estimate algorithms, making the fee market more competitive. The fee market is much more competitive than it used to be. If we accept the premise that competition is healthy for free markets, then it behooves all bitcoin transaction creators to make their fee estimates accessible via public APIs. I suspect that the fee estimate algorithms themselves will often remain closed source, but if the estimates are public then we can more easily watch for abnormal activity.
I suspect that it would be quite similar to what Antoine is currently offering as a visualization on p2sh. Binance must pay these fees to miners to ensure that transactions are processed. Since transaction fees are dynamic, users will be charged according to the current network conditions.
