Nearly nine months after the Senate approved the measure unanimously, 17–0, CADENA remains pending in the House of Representatives.
The Senate unanimously passed Senate Bill No. 1506, the Citizen Access and Disclosure of Expenditures for National Accountability (CADENA) Act, on December 15, 2025.
In the House, several related measures are also pending, including House Bill No. 6761, filed by Rep. Javier Miguel Lopez Benitez, and House Bill No. 6898, filed by Rep. Leila M. de Lima. These bills have been with the Committee on Information and Communications Technology since March 18, 2026.
The CADENA Timeline
Legislative movement begins with SB 1330 introduced amid public scrutiny over discretionary spending.
The bill evolved into CADENA Act, passing the Senate unanimously (17–0) and certified as a LEDAC priority.
The Executive branch re-affirms CADENA as a top priority for mid-2026 enactment.
Sen. Bam Aquino publicly questioned why CADENA had disappeared from the shortened priority list.
The Senate-approved CADENA bill remains pending in the House. It has not become law.
The delay points to a classic tension in reform politics.
Passing a transparency bill through the Senate is easy when public pressure peaks, but steering it through the House—where local project allocations face real-time exposure—is another matter entirely.
How the Proposal Changed
Senator Bam Aquino introduced Senate Bill No. 1330 in September 2025, widely known as the “Blockchain the Budget Bill.” It sought to use digital technology to make government budget and spending information more accessible and traceable.
The proposal subsequently evolved into SB 1506, the CADENA Act. The Senate-approved version establishes a Digital Budget Portal and calls for government budget transactions to be published through a system designed to be timely, accurate, tamper-resistant, interoperable and traceable.

The Vendor-Lock-In Debate
The shift toward a technology-neutral framework also matters in light of a separate debate over how government blockchain systems should be built.
Technologists including Ann Cuisia and Jason Torres raised concerns about vendor bias and potential vendor lock-in, arguing that government requirements should determine the technology—not the other way around. The concern was particularly relevant to the government's emerging blockchain projects, where existing commercial infrastructure could influence future architecture and migration costs.
The concern is not that using a private technology provider is inherently improper. The issue is whether government retains sufficient data ownership, interoperability, portability and freedom to change providers over time.
What We Know
The Senate-approved CADENA text requires disclosure of government budget transactions through a Digital Budget Portal and establishes the National Budget Transparency and Accountability Council (NBTAC) to oversee implementation.
The bill also provides for phased implementation rather than immediate government-wide deployment.
That distinction matters.
CADENA is designed to improve the integrity, accessibility and traceability of government records. It does not, by itself, establish a system capable of independently verifying whether a physical project was actually completed, whether materials were delivered, or whether a project's price was reasonable.
Those questions would still require auditing, procurement review, investigation and, where appropriate, physical inspection.
What the Bill Says vs. What It Doesn't
Public Messaging vs. Legislative Text
“Complete spending disclosure across all government levels.”
Creates a disclosure framework for government transactions covered by the measure. It should not be described as an automatic mandate covering every local-government transaction.
“Real-time, day-one budget tracking.”
The bill provides for phased implementation rather than full government-wide deployment on day one.
“Technology that automatically ends corruption.”
A tamper-resistant record can make alteration and concealment harder to hide. It cannot establish that a physical project was completed, that materials were delivered, or that a government purchase was reasonably priced.
The Numbers
The Senate-approved CADENA bill contains specific compliance requirements and penalties.
Compliance Mandates & Criminal Penalties
The bill provides a seven-working-day disclosure period for covered records.
The bill provides for a fine of up to ₱3 million for specified violations.
Section 17 provides severe imprisonment terms of six years and one day up to 15 years for specified willful violations.
The implementation framework is phased, with full government-wide implementation contemplated within three years.
The Counterargument
One argument against moving too quickly is administrative readiness.
A system requiring agencies to publish, certify and maintain machine-readable government records would require reliable connectivity, digitized records, trained personnel, cybersecurity controls and sustained funding.
The bill addresses implementation through a phased rollout and assigns DICT responsibilities for technical assistance and systems integration.
The practical question is therefore not simply whether the technology can work. It is whether government agencies can implement and maintain the required systems consistently, securely and accurately.
The Gap
The central issue in CADENA is the difference between data integrity and physical reality.
A cryptographically protected record can make it significantly harder to alter a transaction history without detection. But the technology cannot independently establish that a government-funded road was actually built, that a flood-control structure works as intended, or that the price paid for a project was reasonable.
If an agency pays ₱100 million for an overpriced flood-control structure, CADENA could preserve and expose the digital trail of that transaction. Determining whether the structure was properly built, whether the price was justified and whether the public received value for money would still require the work of auditors, investigators, journalists and citizens.
In other words: CADENA can strengthen the paper trail. It cannot replace oversight.
What Remains Unclear
The House's official legislative records show that the principal House counterparts remain pending with the Committee on Information and Communications Technology.
What is less clear is why the measures have not yet advanced to a House vote.
Unless House leadership or the committee provides a specific explanation, it would be premature to attribute the delay to political resistance, an unwillingness to expose local spending, or any other particular motive.
The verifiable fact is simpler: the Senate has passed its version, while the House has yet to complete its legislative process.
The Unpeeled Verdict
CADENA represents a significant attempt to use digital infrastructure to strengthen transparency in public spending.
Its most important feature may not be the use of blockchain or distributed-ledger technology itself, but the proposed requirement that government financial records become more accessible, traceable and resistant to undisclosed alteration.
At the same time, the bill should not be sold as a technological cure for corruption.
A transparent digital record can show where money went. It cannot, by itself, prove that the government received what it paid for.
The Senate has already acted. The next question is whether the House will advance its counterpart measures and, ultimately, whether Congress can agree on a final version.
Until then, CADENA is a proposal—not a law.
The Final Question
If the public is being asked to trust a system designed to make government spending more visible, the standard should be simple:
Can citizens independently see what was approved, what was spent, who was paid, and what was actually delivered?
That is the promise CADENA can realistically be judged against.
