Developed with the Department of Information and Communications Technology and the Department of Budget and Management, this deployment secures official budget records on blockchain. It creates a public verification layer that preserves document integrity, provenance, and long-term accountability across government systems.

The Problem
Philippine public budget records are published through official portals and agency systems, but publication alone does not guarantee long-term integrity. Once documents are released, it becomes difficult to independently verify whether a record remains final, unchanged, and aligned with the original approved version.
As records move across agencies, platforms, and administrations, confidence depends largely on custodianship rather than technical proof. Fragmented systems, limited provenance, and shifting reference points make audits, dispute resolution, and long-term accountability harder to sustain.
Solution
BYC Ventures, in collaboration with the DICT and DBM, developed the Digital Bayanihan Chain as a public reference and verification layer for official budget records, built on Lumen’s Blockchain-as-a-Service infrastructure and aligned with the Digital Public Assets framework.
The system anchors authoritative government documents to a neutral public ledger using cryptographic hashes, timestamps, and unique record structures. This creates immutable integrity proofs, preserves append-only provenance, and enables independent verification while keeping core government databases, workflows, and governance under sovereign control.
