FREQUENTLY ASKED QUESTIONS
Concise answers to the most common questions about the Bitcoin network state shown above.
What is the mempool?
The mempool is the queue of Bitcoin transactions that have been broadcast to the network but not yet included in a block. Miners pick transactions from the mempool based on fee rate. When the mempool is full, fees rise; when it is empty, fees drop.
What does sat/vB mean for Bitcoin fees?
sat/vB is satoshis per virtual byte - the price you pay per unit of block space your transaction occupies. A higher sat/vB fee means a miner is more likely to include your transaction in the next block. Typical next-block fees range from a few sat/vB during quiet periods to hundreds during congestion.
When is the next Bitcoin halving?
Bitcoin halves the block subsidy every 210,000 blocks, roughly every four years. The next halving occurs at block 1,050,000. The countdown above estimates the date based on the current block height and the 10-minute average block time.
How is network hashrate measured?
Hashrate is the total computational power miners contribute to securing Bitcoin, expressed in exahashes per second (EH/s). It is estimated from the rate at which blocks are being mined relative to the current difficulty. Mempool.space uses a three-day moving average for the figure shown here.
What is the difficulty adjustment?
Bitcoin re-targets its mining difficulty every 2,016 blocks (about two weeks) so that blocks are produced roughly every 10 minutes on average. If miners are finding blocks faster, difficulty rises; if slower, difficulty falls. The percentage above is the projected change at the next retarget.
How often does this page update?
The underlying snapshot from mempool.space is refreshed every five minutes by a server-side cron. While this page is open in your browser, it polls the snapshot every 60 seconds and updates the numbers in place. No personal data is involved on the read path.
