Session
Existing studies of coinjoin ecosystem offer little information beyond tx detection and aggregation of stats visible on-chain. The talk explain combination of on-chain tx analysis, coordinators monitoring, and active coinjoin participation to: 1) estimate the number of active users at a time, 2) detect previously unknown coordinators, 3) retrospectively observe prominent activity patterns and 4) deliver continuously updated ecosystem insights at https://crocs-muni.github.io/coinjoin/. The goal is to support informed decisions by coinjoin end-users.
