A distributed ledger lets many independent validators agree a unit of renewable electricity was generated exactly once, without a central authority.
block confirmed when votes >= threshold * nodes
REC == 1 MWh renewable generation, unique serial
- Validator nodes — nodes in the distributed ledger network confirming REC issuance.
- Network connectivity — how densely validators gossip transactions to each other.
- Certificate issuance rate — pace at which renewable generators mint new certificates.
- Consensus threshold — fraction of validators that must agree before a REC is confirmed, preventing double-counting.
Blockchain-tracked RECs solve the double-counting and greenwashing problems that plague paper renewable-energy certificate registries.
