Blockchain the budget bill: Game-changer or pipe dream?

DECODED: TECH, TRUTH, AND THREATS

By Art Samaniego

For many Filipinos, the term “blockchain” can sound unfamiliar and overly technical. But at its core, it’s a digital ledger or a notebook that keeps a record of every transaction, written down and stored so that it can’t be changed or erased.

The difference is that this notebook is not kept in a single drawer in one office. Instead, it is copied and shared across many computers. Whenever something is added, whether a payment, a budget release, or a record, it appears on all copies simultaneously. Once written, it cannot be erased or changed without everyone noticing.

Think of it like the barangay’s logbook during fiestas or projects. When expenses are recorded in ink, barangay residents can check the notebook to see how money was used. Blockchain applies that idea on a national scale, using computers to make the record more permanent and harder to tamper with.

The promise of transparency

Senate Bill No. 1330, dubbed the “Blockchain the Budget Bill” and filed by Senator Paolo Benigno “Bam” Aquino, is ambitious: it seeks to place every peso of the national budget on a blockchain-powered system.

The proposal would mandate the Department of Information and Communications Technology (DICT), in collaboration with the Department of Budget and Management (DBM) and the Commission on Audit (COA), to develop a National Budget Blockchain System that enables real-time tracking of funds by anyone.

At first glance, the appeal is clear. Blockchain’s immutable ledger ensures that once money flows from the General Appropriations Act to agencies, contractors, or local governments, those records are stamped, permanent, and visible. This could empower citizens, journalists, and watchdog groups to “follow the money” with unprecedented accuracy.

The technical foundation

Senate Bill No. 1330 is not an abstract idea. The DBM has already tested BayaniChain, logging budget documents onto the Polygon blockchain since July 2025. (The problem is, I tried it and I couldn’t understand how it works.

After a few minutes, I was lost. The terms were unfamiliar, the process felt abstract, and I wasn’t even sure what I was looking at half the time.) The DICT, meanwhile, is piloting eGovChain to secure government transactions. These efforts form the technical foundation that SBN 1330 seeks to institutionalize on a national scale.

If expanded, the system could turn budget monitoring into a public-facing dashboard, eliminating the information gap that fuels suspicion and corruption.

The obstacles ahead

1. Political resistance. Transparency threatens entrenched interests. The very actors who benefit from opaque budgeting processes may resist full implementation, slowing progress or limiting coverage to select projects.

2. Garbage in, garbage forever. Blockchain ensures the integrity of records once they are entered. However, if the data uploaded is already compromised, such as padded project costs or ghost suppliers, the system merely preserves falsehoods on-chain.

3. Scalability. The Philippine budget involves millions of transactions annually. Replicating each movement of funds on a blockchain requires infrastructure, bandwidth, and training across agencies, resources that are often scarce.

4. Cybersecurity risks. While blockchain itself is tamper-resistant, the nodes, wallets, and application programming interfaces (APIs) connected to it are still vulnerable. A compromised node could undermine confidence in the system.

5. Public accessibility. Transparency is meaningless if the interface is too complex. For this bill to succeed, the system must be usable by ordinary citizens, not just auditors and IT specialists.

A cautious outlook

In the short term, the “Blockchain the Budget Bill” could produce pilot dashboards that serve more as proof-of-concept than systemic reform. In the medium term, selective integration of budget releases might improve oversight in specific agencies. In the long term, when paired with procurement and auditing tools, blockchain has the potential to transform how Filipinos perceive public funds.

But success hinges on more than code, it requires political will, sustained funding, and a cultural shift toward open governance.

Bottom line

Blockchain cannot eliminate corruption on its own. What it can do is raise the cost of hiding it.

Whether the “Blockchain the Budget Bill” becomes a historic step in public finance transparency or just another digital experiment depends not on the technology itself, but on the willingness of institutions to let the sunlight in and get rid of the ghosts.
