Reference Case · Public Sector · Digital Assets
A sovereign wallet that holds its value when the currency doesn't.
A private-blockchain wallet that converts a public incentive program into USD-pegged digital tokens — preserving value through inflation, and turning a paper handout into an auditable, programmable intelligence layer for the state.
The thesis
Value engineered to stay flat while the peso falls.
The original award was paid in pesos, so inflation quietly taxed every recipient between issuance and redemption. Pegging the token to the U.S. dollar removes that erosion — the line holds whether someone cashes out at graduation or saves for months.
The challenge
The Government of the Province of San Luis, Argentina had run a successful student graduation-incentive program since 2010, offering a financial award to every student who earned their high-school diploma. It worked: provincial graduation rates climbed roughly 20%, positioning San Luis above the national average.
But the mechanism for delivering those awards had a structural problem. Students received paper certificates, redeemed physically at a bank for Argentine pesos. Given Argentina's persistently high inflation, the value of each award eroded rapidly — whether a student redeemed immediately or waited. The program's impact was being undermined by the very currency it depended on.
The program's impact was hostage to the currency it depended on. The fix wasn't a bigger award — it was a better instrument.
San Luis Governor Dr. Alberto Rodríguez Saá had already named digital inclusion a provincial priority:
The first human right is one that is not born from the economy, but from science and technology.
By 2020, provincial leaders saw blockchain as the mechanism to modernize the award program, protect its value, and promote financial literacy among digital-native students. They brought in our team — then operating as AccelOne Argentina, the entity Volkom acquired — to build it.
The Volkom approach
Volkom created Billetera Activa, a private-blockchain platform that replaces paper graduation certificates with digital tokens backed 1:1 by the U.S. dollar. Because the tokens are USD-pegged, their value is preserved regardless of peso devaluation — whether a student redeems immediately after graduation or saves for months.
The solution met the government's core requirements: draw in digital-native users, make financial data accessible and secure, and encourage savings and smart money habits by removing the inflation vulnerability baked into the original paper-based system.
The work ran in parallel streams — analysis, design, build, and QA at once — against a hard, non-negotiable launch date tied to the graduation calendar. An independent firm ran adversarial security testing before a single token was issued.
When we started this project, we knew there were opportunities to serve our community with blockchain technology, with a very specific goal in a very short amount of time. Our team was able to envision the opportunity to make a real impact. We are very grateful for the team's responsiveness and willingness to work together from the beginning — taking our idea and turning it into an application with real impact on the community, giving their engineers the autonomy to be creative and diligent.
The product
One wallet: balance, transfers, and savings — held in ASL tokens.
Billetera Activa. Onboarding by national ID, a live balance in Activos San Luis (ASL) tokens shown alongside its peso equivalent, peer-to-peer transfers, and in-app services — built mobile-first for a digital-native population.
The architecture
Security & governance
Government money demands government-grade controls. Security wasn't bolted on — it was the architecture. Officials issue and manage tokens through a controlled console, while every movement writes to a ledger no one can quietly edit.
Identity, authorization, and auditability were treated as first-class features, validated by independent penetration testing prior to launch.
- Multi-factor authentication on every account
- Biometric validation for transactions
- KYC-based digital identity verification
- Fully auditable issuance & redemption ledger
- Role-based, restricted access controls
- Independent third-party cybersecurity testing
Outcomes
Beyond the first program
Scalability was a requirement, not an afterthought. The same platform can issue and govern tokens for any eligible population — other grants, subsidies, or inclusion initiatives — without rebuilding the core.
One platform, many programs. The state gets a reusable rail for value distribution instead of a single-use disbursement.
Configurable access by user type, an auditable ledger across every program, and infrastructure built to extend mean the model travels: from one province's graduates to any government's social-program portfolio.
Questions, answered
What is the platform, in one line?
A private-blockchain wallet that issues USD-pegged digital tokens, replacing paper award certificates and protecting their value against local inflation.
How does it solve the inflation problem?
Tokens are pegged 1:1 to the U.S. dollar, so purchasing power is preserved whether a recipient redeems immediately or holds for months — unlike a peso payout that erodes daily.
What's the technology stack?
Hyperledger Fabric for the permissioned ledger, Flutter for the mobile wallet, Node.js for APIs and integrations, ReactJS for the back-office console, and AWS with CI/CD plus Docker for delivery and runtime. Security spans MFA, biometric validation, and KYC.
How fast can it launch?
This reference build went from concept to production in five months against a fixed deadline, using parallel analysis, design, build, and QA, with independent security testing before launch.
Can it extend to other programs?
Yes. The ledger, identity, and access-control layers are program-agnostic, so a government can stand up new token programs on the same platform without rebuilding it.
