Public procurement at the Central Bank of Liberia, on the record.

Every tender notice, sealed bid, evaluation score, award, and contract amendment is recorded in a hash-chained audit substrate and anchored hourly to a public timestamp authority. Register your firm, read the rules of the game, and bid with confidence.

Every transition rule-gated

Each state change — from publication to award — is validated against encoded PPCC clauses and donor-framework rules. The system cites the rule and shows the evaluation.

Sealed bids, compartmentalised review

Bids are X25519-sealed at submission and decrypted only at quorum opening. Evaluator workspaces redact identity so scoring runs on substance, not familiarity.

Hash-chained audit, anchored

Every action emits an immutable event. The chain is hash-linked, signed hourly to a public timestamp authority, and externally verifiable end-to-end.
