Live Bitcoin network

Public data from independent explorers. Numbers are labelled as measurements or estimates, never blended into false precision.

Live pulse

Four gauges refreshed every minute: the countdown to the next halving, how busy blockspace is, the latest blocks, and the upcoming difficulty adjustment.

    Blocks

    Block height

    What does this mean?
    The number of blocks in the longest valid chain. Each block is a batch of transactions locked in by proof of work.

    Transactions in latest block

    What does this mean?
    How many transactions the miner included in this block. It varies with demand and transaction sizes.

    Latest block size

    What does this mean?
    Blocks are bounded by weight (4 million weight units), not by a fixed byte count.

    Mempool

    Pending transactions

    What does this mean?
    Transactions nodes have seen but that are not in a block yet. Each node keeps its own view.

    Mempool size

    What does this mean?
    Combined virtual size of all pending transactions. Roughly 1 MvB equals one block's worth of work.

    Suggested fee (~30 min)

    Estimate
    What does this mean?
    An estimate derived from the current mempool. Fees are a market: any estimate degrades when demand spikes suddenly.

    Just-arrived transactions

    Refreshes every 15 s

    Unconfirmed transactions public nodes have just seen. They are in no block yet and can still be replaced.

    Mining

    Hashrate (3-day average)

    Estimate
    What does this mean?
    Hashrate cannot be measured directly. It is inferred from how quickly blocks are found at the current difficulty.

    Next difficulty change

    Estimate
    What does this mean?
    Difficulty retargets every 2,016 blocks so that blocks take ten minutes on average.

    Current block subsidy

    Protocol rule
    What does this mean?
    The new bitcoin created per block. It halves every 210,000 blocks and is fixed by consensus rules, not estimated.

    Supply

    Issued supply

    Protocol rule
    What does this mean?
    Computed from block height and the issuance schedule. This is not the same as spendable coins: lost keys are still counted.

    Maximum supply

    Protocol rule

    21,000,000BTC

    What does this mean?
    An upper bound implied by the halving schedule. Because subsidies round down to whole satoshis, the real final total lands slightly below it.

    Lightning

    Public Lightning data describes announced nodes and channels only. Private channels exist and are not counted, so treat these figures as a floor, not a total.

    Announced nodes

    What does this mean?
    Publicly announced Lightning nodes.

    Announced channels

    What does this mean?
    Channels announced to the public graph.

    Public capacity

    What does this mean?
    Sum of public channel capacity. Private channels are missing, so treat this as a floor.
