How Bitcoin Transaction Acceleration Works

A clear explanation of why Bitcoin transactions get stuck, how BTCBoost accelerates them, and what alternatives like RBF and CPFP exist.

Why Transactions Get Stuck

01

Every Bitcoin transaction broadcasts to the global network and lands in the mempool — a waiting room for unconfirmed transactions.

Miners pick transactions from the mempool to include in the next block. They prioritize transactions offering the highest fee rate (sat/vB) — satoshis per virtual byte.

When you send with a low fee rate during periods of high demand, your transaction sits at the back of the queue. The mempool can hold thousands of transactions, and a low-fee TX may wait hours or days for confirmation.

Mempool Queue (simplified)

120 sat/vB
Mined immediately
80 sat/vB
Next few blocks
20 sat/vB
Hours wait
5 sat/vB
Stuck — days

How BTCBoost Accelerates Your TX

02

BTCBoost rebroadcasts your TXID directly to our partner mining pool API endpoints. Major pools receive a direct request to prioritize including your transaction.

We submit to multiple pools simultaneously — including ViaBTC, BTC.com, and others — covering approximately 78% of the Bitcoin network hashrate.

This doesn't change your transaction fee — instead, it puts your transaction on the radar of pool operators who can choose to include it at their discretion, especially during lower mempool activity periods.

Alternative: RBF (Replace-By-Fee)

03

If your wallet supports RBF (Replace-By-Fee), you can replace your stuck transaction with a new one that has a higher fee. Most modern wallets support this.

The replacement transaction must spend the same inputs (UTXOs) but offer a higher sat/vB rate. Miners will prefer the higher-fee version.

RBF is the most reliable way to speed up a stuck transaction, but it requires wallet support and you must pay an additional fee bump.

👨‍👧

Alternative: CPFP (Child Pays for Parent)

04

CPFP (Child Pays for Parent) works when you're the recipient of an unconfirmed transaction. You create a new transaction spending the unconfirmed output with a high enough fee to cover both the parent and child transactions.

Miners see the combined fee rate and are incentivized to confirm both transactions together. This is useful when you're waiting to receive funds.

CPFP requires a bit more technical knowledge but is built into some wallets like Electrum and Bitcoin Core.

Bitcoin Transaction Glossary

TXID
Transaction ID — a 64-character hexadecimal string that uniquely identifies a Bitcoin transaction on the blockchain.
Mempool
Memory pool — a staging area where unconfirmed transactions wait to be picked up by miners and included in a block.
sat/vB
Satoshis per virtual byte — the fee rate metric used by Bitcoin miners to prioritize transactions.
RBF
Replace-By-Fee — a protocol rule allowing a sender to replace an unconfirmed transaction with a higher-fee version.
CPFP
Child Pays for Parent — a technique where a new transaction spending an unconfirmed output pays a high enough fee to incentivize miners to confirm both.
Block
A bundle of confirmed transactions added to the Bitcoin blockchain approximately every 10 minutes.
