Adoption Velocity

Definition

Whether an output type is gaining or losing ground, rather than how much it holds. A line above zero means that type's share of outputs grew over the window; below zero means it shrank.

The figure is in percentage points, not percent. Taproot going from 22% of outputs to 11% fell by 11 points and by 50%. Both describe the same move, and this chart plots the first.

The share is smoothed before it is differenced, so a point compares the trailing average now against the same average one window earlier, reaching back about twice the window: roughly two months daily, two days per block.

Every type is drawn, so the lines always add up to zero, which does not mean users moved between them. Through April 2026 P2WPKH rose more than thirteen points while Taproot fell more than eleven, for separate reasons: inscriptions dropped by about two thirds, roughly halving Taproot output creation, while P2WPKH's own output count rose by more than a quarter.

How it is measured

Each type's outputs as a share of the nine classified output types, averaged across the window, minus that same average one window earlier.

The window follows the resolution. Per block it is 144 blocks, a day at the ten-minute target, though a real day has held between 98 and 197 blocks over the last year. At daily resolution it is 30 days.

All nine classified output types are drawn: P2PKH, P2SH, P2WPKH, P2WSH, P2TR, P2PK, bare multisig, pay-to-anchor and unclassified scripts. Because they are the whole denominator, the lines sum to zero at every point, so whatever one type gains the others gave up.

Each of the quiet ones has its own era rather than being permanently flat. P2PK held virtually every output in January 2009 and about 12% of them by late 2010. That handover is the largest move on the chart, and it is why P2PK and P2PKH are mirror images through 2009 and 2010: no other address type existed yet, so one type's loss was the other's gain, by more than 40 points.

What P2PK keeps after that is almost entirely the block reward. Across late 2010 and early 2011 the count of P2PK outputs and the count of coinbase outputs are within half a per cent of each other, so what the line tracks from then on is miners paying themselves to a public key while ordinary payments had moved to P2PKH.

Bare multisig peaks during the Stamps period in 2023 and P2WSH during the Ordinals ramp. P2A is the newest line and the busiest of the quiet ones: pay-to-anchor outputs did not exist before June 2024 and have moved almost four points in a thirty-day window since. Unclassified scripts are whatever is left once the eight named types are taken out, and that now averages about a hundredth of a per cent. On a short range most of them sit on zero; use the legend to hide any line that crowds the one you are reading.
