About this metric
What it measures
CoinJoin Output Count totals transaction outputs classified as belonging to CoinJoin activity each day, in outputs. CoinJoin combines inputs from multiple participants in a shared transaction to make input-to-output ownership links harder to infer.
How to read it
More outputs indicate greater activity under the CoinJoin classification, but may also reflect larger rounds or repeated participation. The daily count reached 32,285 on March 1, 2023, compared with a 2021 yearly high of 8,878; the scale of output creation has varied considerably across periods.
Output count is not participant count, BTC volume or proof of anonymity. Identification relies on transaction patterns, and changing round structures can alter what is recognized. The same coins can pass through several rounds, so outputs cannot be added up into a unique stock of mixed BTC.

FAQ
Why count CoinJoin outputs rather than transactions?
One collaborative transaction can create many outputs. Counting outputs captures that scale, while a transaction count would count the whole round just once.
Does a higher output count mean more unique CoinJoin users?
Not necessarily. A participant can receive several outputs or join multiple rounds, and a round can change its number of outputs without adding users.
Does CoinJoin output count measure how private Bitcoin is?
No. It records recognized collaborative output creation, not how well ownership is concealed in any particular case. Privacy depends on transaction structure and behavior before and after the round.
