Taproot Economic Gap™
Two P2TR proportions on one axis: the share of P2TR outputs among outputs of the four types P2TR, P2WPKH, P2SH and P2PKH, and the share of the circulating supply held in Taproot outputs. The chart compares their levels; the gap is not, by itself, a measure of dust or of economic transfers.
What is it?
The Taproot Economic Gap™ overlays two proportions computed over the same period: the share of P2TR outputs among outputs of the four types the calculation sums, P2TR, P2WPKH, P2SH and P2PKH, and the share of total BTC supply held in P2TR outputs. The first is a flow of created outputs, the second is a stock of unspent coins, and their denominators differ: the sum of outputs of those four types on one side, total supply on the other. Outputs of other script types are not counted in the first proportion. The gap between the two curves therefore describes a relation between two proportions. It does not classify outputs by use and does not measure a quantity of dust.
How to read
Two lines on the same chart. The P2TR output line is the share of P2TR outputs among outputs of the four types P2TR, P2WPKH, P2SH and P2PKH, by count. The P2TR supply line is the share of total supply held in P2TR outputs. When the first exceeds the second, P2TR outputs account for a larger share of the four types' output total than of the value held. When the two lines converge, the two proportions are close. The chart does not say which activity produces either proportion.
Key zones
The ratio between the output share and the supply share summarises the comparison. A ratio above 1 means the output share exceeds the supply share. A ratio below 1 means the opposite. The chart sets no threshold beyond which a particular cause would dominate, and no zone qualifies the uses.
What to observe
Monitor the trend of each proportion and of their ratio. A move in the output share can come from a change in the total of the four counted output types without any change in the P2TR output count. A move in the supply share can come from a change in total supply or from spending P2TR coins. The most robust reading compares the two curves over the same window and relates them to the other Taproot metrics, supply share and output count.
Historical context
Taproot was activated at block 709,632 on 14 November 2021. The P2TR share of the four counted output types stayed low during the first months, then rose from 2023. The share of supply held in P2TR outputs progressed more slowly over the same period. The chart shows these two trajectories; it does not establish what caused them.
Expert notes
The two series do not share the same basis: a flow of counted outputs on one side, a stock of unspent coins on the other. The denominator of the first proportion is the sum of P2TR, P2WPKH, P2SH and P2PKH outputs, not the whole network output set. Their ratio therefore does not read as an average value attached to a single output. Change outputs also matter: a transaction can create a P2TR output that returns to the same holder and corresponds to no economic transfer. Those outputs are counted as P2TR, like any other.
Common mistakes to avoid
The gap is neither a measure of dust nor a classification of uses. It does not attribute a rise to a category of activity, and it does not judge Taproot's success. A wide gap does not prove that P2TR outputs are small in absolute value: it only indicates that their share of the output count exceeds their share of the supply held. Finally, the two proportions have different denominators, so a rise in one does not read as a mechanical fall in the other.
