In the unspent output model, a mixing pattern shows up as a shape in the transactions. Many inputs gather into one transaction, and then a set of outputs goes out to different addresses. The address format carries no flag for it.

Reading inputs and outputs

Count the inputs that were spent into the transaction and the outputs it created. Match amounts in satoshis, because that is the unit the transaction records. The block reward page equates 5,000,000,000 satoshis with 50 BCH, so keep satoshi figures exact before converting.

Phrasing the pattern

Call it consolidation followed by distribution. Attach the transaction references, the amounts and the heights.

Frequently Asked Questions

No. An address starting with q or p says only which type of locking it uses. The pattern lives in the transactions, in how inputs and outputs are arranged.
