The deployment was announced around October 26, 2026. It drew wider media coverage on November 9-10, 2026.
Each evidence container carries a QR code. When someone scans that box or a lab produces a result, the system generates a SHA-256 hash, which is a fixed-length digital fingerprint of the underlying data.
That fingerprint is then anchored to the Cardano blockchain. If anyone later alters the record, its fingerprint will no longer match the one stored onchain.
The blockchain does not hold the evidence itself. It holds proof of what the evidence record looked like at a specific moment.
Each person who handles evidence gets a unique identifier. This targets chain-of-custody risk, the weak point where evidence passes between officers, storage rooms and labs and nobody can say for certain who had it and when.
Officers keep their usual workflows, scanning boxes and logging results, while the blockchain activity happens in the background.
The numbers so far
The FMS has recorded more than 156,000 transactions on the Cardano mainnet. That works out to an average of approximately 11,000 transactions per month.
The project did not appear out of nowhere. TrivolveTech previously received 550,000 $ADA through Catalyst Fund 12, the community-driven grant program run within the Cardano ecosystem.
The developer now wants a much bigger slice of the treasury. It has proposed a follow-on project called the Police Force Management System, or PFMS, and is seeking 9.6 million $ADA from the Cardano treasury to build it.
That request is roughly 17 times the earlier Catalyst grant. As of late October 2026, the proposal was under community vote.
TrivolveTech is targeting an estimated 1.53 million transactions in the PFMS’s first year. That would be nearly ten times the total the FMS has recorded to date. On a monthly basis, it implies an average of more than 127,000 transactions, compared with the current pace of about 11,000.
Why this matters beyond Cardano
Chain of custody is one of the oldest problems in criminal justice. A piece of evidence is only as credible as the paper trail behind it, and a gap in that trail can weaken an entire case.
Traditional systems rely on signatures, logbooks and centralized databases. A public blockchain offers a record that sits outside any single department’s control.
The Cardano Foundation plans to publish a detailed case study on the initiative.
What this means
The treasury vote is the near-term event to watch. Cardano’s on-chain governance lets the community decide how treasury funds are spent, and a 9.6 million $ADA request is a meaningful test of how voters weigh proven deployments against new proposals.
There are caveats worth keeping in mind. Transaction counts measure activity, not impact, and the case for the system ultimately rests on whether it improves how evidence holds up in investigations and courtrooms.
For other governments weighing similar tools, the wallet-free design may be the most transferable lesson. Asking police officers to manage private keys would be a hard sell. Hiding the blockchain behind a QR scanner removes that barrier.
