Question 1

What is carbon attestation?

Accepted Answer

Carbon attestation is the process of cryptographically proving the carbon emissions associated with energy consumption. EnergyAtIt uses SHA-256 hash chains to create tamper-proof records linking meter readings to carbon intensity data.

Question 2

How does hash-chained carbon attestation work?

Accepted Answer

Each carbon record includes the SHA-256 hash of the previous record, creating an append-only chain. Any tampering breaks the chain, which can be verified in one API call.
