Address Type Count

Daily totals of outputs by script type, one band per type

Short ranges plot one point per block, about one every ten minutes. Longer ranges plot one point per day, computed from every block in that day. How it is computed depends on the chart: some average, some total the day up, some are a ratio of the day's sums, and each chart says which. Either way a brief spike inside a day is smoothed away.

OverlaysExtra context drawn on top of the chart. Event markers are vertical lines at dated moments; a comparison series is a second set of numbers on its own axis at the right.

Event markers

Every 210,000 blocks, roughly every four years, the block subsidy halves. Fees are the other part of what a miner collects and do not halve with it. Four halvings have happened so far.

A BIP is a Bitcoin Improvement Proposal: a design document for a change to the protocol. These lines mark the dates that proposals such as SegWit and Taproot became active on the network.

Releases of Bitcoin Core, the software most nodes run. A release does not change consensus rules by itself, but it often changes what transactions a node will relay, which can show up in these charts.

Dated moments outside the protocol that moved the numbers: exchange failures, country-level bans, the first Ordinals inscriptions.

Comparison series

The BTC price in US dollars, drawn on its own axis on the right. Sampled every 4 days, which is all the source provides for the full history, so a range shorter than that cannot draw it. Price crosses six orders of magnitude, so it usually wants the logarithmic setting beside it.

The total size of the block chain on disk, growing as blocks are added. An archival node keeps every byte of it; a pruned one verifies the same blocks and then discards the old ones.

About this metric

Definition

The type of address each new output pays to. Every output commits to a script, and the shape of that script says which format the receiver gave out: a legacy '1', a '3' that commits to a hash of the spending conditions rather than to a single key, a SegWit 'bc1q' or a Taproot 'bc1p'. Modern wallets often put a SegWit program behind a '3', which is why that band did not empty when 'bc1q' arrived. One band is not an address at all: P2PK paid a public key directly, before address formats existed. It has not stopped entirely, but it arrives in bursts rather than a trickle: roughly one block in seven hundred carries one, and most days have none at all. Counting them is how the chain shows a format being adopted.

How it is measured

Counts of outputs created per script type, from the classification stored per block. Daily values are totals for the day, not per-block averages: 3.0 per block over 10 blocks is 30. Coinbase outputs are excluded, because ingestion skips that transaction.

The P2SH band is the one that hides things. A '3' output is only a commitment to a hash, so a nested SegWit program, a multi-signature arrangement and a timelock are the same shape on creation, and the script behind it is revealed only when the output is spent. This chart counts outputs as they are created, so it cannot separate them, and no column here does.

A band can also start before the rule that gave it meaning, because a script shape is valid to create before the network agrees what it means. Six P2SH outputs sit in five blocks from 2012-03-07, and the BIP-16 marker is at block 173,805 on 2012-04-01, nearly four thousand blocks later. Taproot does the same, with outputs from 2019 against a 2021 activation. Turn on the BIP activations overlay to see it: the marker lands well to the right of where the band begins.
