ECO/CPO-DAG: Reference Implementation

Year: 2026

Type: software

Abstract: Reference implementation of the ECO/CPO-DAG contradiction-based accountability layer for adversarial supply chains, accompanying the paper. Includes the ecodag protocol package (Event Claim Objects, Contradiction Proof Objects, the five EPCIS 2.0 constraint predicates, blame resolution, and a zero-knowledge quantity range proof), a standalone independently-citable contradiction benchmark, a seed-reproducible measured evaluation (scripts/reproduce.py + results/), and the test suite. Honesty notes: commitments/ZK run over a MODP integer group with a naive Sigma protocol (a conservative upper bound, not curve-based Bulletproofs); hashing is BLAKE2b; all traces are synthetic.
