TOP-5 Methods to Speed Up Bitcoin Transactions
Payments in bitcoins continue to gain popularity worldwide. In November 2021, the price of bitcoin reached an all-time high, approaching $69,000. The record volume of transactions was registered in August 2023 — in one day the network processed over 610 thousand operations.
With the growing number of users wishing to make bitcoin transfers, network load increases. As a result, users may face delays in processing transactions.
It is important to remember that bitcoins and other cryptocurrencies operate on blockchain technology. This technology represents a chain of data blocks, each of which has a limited capacity. In the case of bitcoin, the block size does not exceed 4 megabytes.
Therefore, during periods of high network usage, some transactions enter a waiting queue called the “mempool.” Sometimes a transaction may remain in the mempool for several days before it is processed by a miner and included in a block. The transaction status can be checked using specialized blockchain explorer services.
Nevertheless, there are methods that allow you to speed up bitcoin payments. We will discuss them below.
Brief Bitcoin Overview
The history of bitcoin begins on October 31, 2008, when Satoshi Nakamoto published the paper “Bitcoin: A Peer-to-Peer Electronic Cash systеm,” which outlined the rules of the systеm. On January 3, 2009, the first block of the cryptocurrency was created, in which 50 bitcoins were mined.
The bitcoin exchange rate was first set on October 5, 2009: 13 bitcoins for one cent. The first known purchase with bitcoins took place on May 22, 2010, when a US resident, Laszlo Hanyecz, exchanged 10,000 bitcoins for two pizzas, which became the first real-life use of the cryptocurrency. In February 2011, the bitcoin rate equaled the US dollar, and interest in it continued to grow.
Bitcoin attracted users due to decentralization and relative anonymity. Each transaction is confirmed by miners, who record it in blocks forming the blockchain. All network participants have access to this chain of data.
Miners receive a reward for confirming transactions in the form of a fee paid by the sender. The size of the fee directly affects the speed of transaction processing. In addition, miners receive a reward for each mined block, which halves every 210,000 blocks — a process called halving. Details on how halving affects the market can be found in our separate article.
Factors Affecting Bitcoin Transaction Speed
1. Transaction Fee
The user can set the transaction fee themselves or use the recommended amount by the systеm. Since blocks have a fixed capacity and each transaction takes up a different number of bytes, miners choose to process operations with the best “fee / transaction weight” ratio.
For more details on calculating fees, read our article “What is a Blockchain Network Fee and How to Calculate It.”
2. Network Congestion
During periods of sudden increase or decrease in demand, a transaction may “get stuck.” The BTC network processes a maximum of about 7 transactions per second. Miners always prioritize transfers with higher fees. Current network load information can be found on Blockchair.
3. Transaction Size
The larger the transaction, the higher the fee. Typically, for every 1,000 bytes, you need to pay at least 0.0005 BTC. Therefore, larger transfers automatically receive higher priority in the network.
Considering these factors, several methods can be highlighted to speed up bitcoin transactions.
Methods to Speed Up Transactions
1. Increasing the Transaction Fee
The optimal fee is calculated as: transaction weight in bytes multiplied by the price per byte in satoshis (1 BTC = 100 million satoshis). The weight considers the size of the transaction itself (approximately 10 bytes), all inputs (about 148 bytes each), and outputs (about 34 bytes each). The price per byte increases with the demand for transactions.
For example, if the transaction weight is 374 bytes and the price per byte is 138 satoshis, the fee will be 51,612 satoshis (0.00051612 BTC), which at a bitcoin price of $10,000 equals $5.16.
2. rеplace-by-Fee (RBF)
If the transaction fee is too low, miners may delay confirmation. RBF allows replacing an unconfirmed transaction with a new one with a higher fee. This feature is supported by popular wallets: Armory, GreenAddress, Electrum, Exodus, Trezor, etc. Miners receive a reward for both transactions, speeding up processing.
3. Child Pays for Parent (CPFP)
This method works only with bitcoin. The principle is “child pays for parent.” A new transaction is created, spending funds from an old (even unconfirmed) transaction, with a higher fee. Miners are interested in confirming the new transaction, which means the old one is confirmed first. To use CPFP, a wallet that supports this function is required, such as Electrum, Exodus, Trezor, etc.
4. Increasing Transaction Priority
The transaction can be moved to the front of the mempool queue:
- Avoid sending small amounts — they are processed later;
- Use digital signatures or multisignature to increase transaction trust;
- Send the transaction via a trusted server so that external observers mark it as important.
These measures make the transaction more attractive to miners.
5. Transaction Accelerators
If a transaction “gets stuck,” external accelerators can be used. There are free services in the network (bitAccelerate.com, Blockchain.com, bitTools, bitNitro, bitcoinjumper.com) and paid ones (antPool, viaBTC), with acceleration costing from $20.
The principle is simple: the sender enters the transaction hash, and it is pushed through the mempool until confirmed by a miner. Paid services increase the fee and incentivize miners to process the transaction faster.
How to Choose a Method
The simplest way to speed up is to increase the fee, which is supported by most wallets (imToken, Atomic Wallet, Blockchain, etc.). Other methods require skills: for RBF and CPFP, the wallet must support fee editing and creating “child” transactions.
Accelerators carry the risk of fraud, so it is important to check the service reputation and read Bitcoin community reviews before using them.
Conclusion
The speed of transaction confirmation depends on its attractiveness to miners. A high fee and digital signature increase transaction priority. If the transfer is small and not urgent, it is better to choose a period with low network load.
Thus, the correct choice of method and fee calculation allows speeding up bitcoin transactions, minimizing delays, and safely conducting operations via blockchain.
