PEAC Protocol: an open protocol for policy, payments, and receipts
Apache-2.0 licensed. Works anywhere. Adopt just the parts you need.
Path to Standard Adoption
We are working toward multiple independent implementations before 1.0
Originary reference implementation
Independent conformant implementations
Broad adoption and ecosystem
No single implementation has privileged status. Originary is one implementation; we welcome others.
PEAC is designed for adapter-based interoperability. Multiple implementations ensure the protocol remains neutral, open, and resilient.
