What this record proves

One record, three answers.

Every Purchase Receipt holds the same set of answers, in the same format — that is what makes the network checkable by anyone.

01
Who bought
The buying account, identified in whatever way the supporter chose to make public.
02
How much was bought
The credit type and the amount, in metric tons.
03
From which certificates
Every certificate in the allocation — the trail back to the MassIDs it came from.

Position in the cycle

Where the Purchase Receipt fits.

Five contract families cover the path from the material to the attribution of the outcome, across four stages. Each record points back to the one before it.

  1. 01

    Record

    The batch of material is verified and enters the network as a permanent record.

  2. 02

    Certification

    The reduction or the recycling is certified under an active methodology, and the credit is issued.

  3. 03

    Purchase

    The credit purchase becomes a public record, tied to the certificates it came from.

    • Purchase Receipt
  4. 04

    Registration

    The credit leaves circulation and the environmental outcome is attributed for good.
