In brief: AccelOne built Billetera Activa, a private blockchain platform for the Government of San Luis, Argentina, replacing paper graduation award certificates, which lost value to Argentina's inflation, with USD-backed digital tokens. The platform launched in 5 months, achieved 100% student account creation, an 84% token redemption rate, and a 25% voluntary savings rate, meeting all government objectives for accessibility, security, and financial inclusion.
The Government of the Province of San Luis, Argentina had been running a successful student graduation incentive program since 2010. The program offered financial awards to students who earned their high school diplomas, boosting provincial graduation rates by 20% and positioning San Luis above the national average.
But the mechanism for delivering those awards had a structural problem. Students received paper certificates that they redeemed physically at a bank for Argentine pesos. Given Argentina's persistently high inflation, the value of those awards eroded rapidly, whether students redeemed immediately or waited. The program's impact was being undermined by the very currency it depended on.
San Luis Governor Dr. Alberto Rodríguez Saá had already positioned digital inclusion as a provincial priority, stating:
By 2020, provincial leaders saw blockchain as the mechanism to modernize the graduation award program, protect its value, and promote financial literacy among digital-native students. They asked AccelOne to build it.
AccelOne created Billetera Activa, a private blockchain platform that replaces paper graduation certificates with digital tokens backed by the U.S. dollar. Because the tokens are USD-pegged, their value is preserved regardless of Argentine peso devaluation, whether a student redeems immediately after graduation or saves for months.
The solution addressed the government's core requirements: entice digital-native users, make financial data accessible and secure, and encourage savings and smart money habits by removing the inflation vulnerability of the original paper-based system.
AccelOne's team worked in an agile environment with parallel streams of analysis, design, development, and quality assurance to meet the five-month launch deadline. An independent third party was engaged to conduct cybersecurity testing, ensuring enterprise-grade security for government infrastructure.
The full technology stack:
Security was built into the core architecture. The platform implements multi-factor authentication (MFA), biometric validation for transactions, and digital identity verification using Know Your Customer (KYC) best practices. Government officials can create and manage ASL tokens with fully auditable transactions and restricted access controls.
The platform launched successfully, with measurable outcomes across adoption, engagement, and financial behavior:
Billetera Activa was designed with scalability as a core requirement. The platform enables government officials to create and manage ASL tokens for any eligible population, with fully auditable transactions and the ability to restrict access by user type or program.
Multi-factor authentication (MFA) and biometric validation for all transactions
Digital identity verification via Know Your Customer (KYC) standards
Auditable token issuance and redemption ledger
Configurable access controls for different user groups
Scalable infrastructure to extend beyond the initial student cohort
The architecture enables San Luis, or any government, to extend the model to other social programs, grants, or digital inclusion initiatives without rebuilding the underlying platform.
What is Billetera Activa?
Billetera Activa is a private blockchain platform built by AccelOne for the Government of San Luis, Argentina. It allows students to store and redeem digital tokens backed by the U.S. dollar, replacing paper graduation award certificates. The platform protects award value against Argentina's high inflation and promotes financial literacy among digital-native students.
How did AccelOne solve Argentina's inflation problem for student graduation awards
AccelOne replaced paper graduation certificates, which lost value rapidly due to Argentina's inflation, with USD-backed digital tokens stored in a mobile wallet app. Because the tokens are pegged to the U.S. dollar, their value is preserved regardless of peso devaluation, whether students redeem immediately or save for later.
What technology stack was used to build Billetera Activa?
Billetera Activa was built using Hyperledger Fabric for the private blockchain, Flutter for the mobile wallet app, Node.js for the API and integrations, ReactJS for the back-office web application, AWS for cloud services with CI/CD pipelines, and Docker containers. Security features include multi-factor authentication (MFA), biometric validation, and KYC digital identity verification.
How long did it take AccelOne to build and launch Billetera Activa?
AccelOne built and launched an operational version of Billetera Activa in five months, in time for December graduation ceremonies. The team used an agile methodology with parallel analysis, design, development, and QA to meet the hard deadline. An independent third party also conducted cybersecurity testing before launch.
What were the results of the Billetera Activa blockchain platform?
100% of eligible students created accounts and 84% redeemed their tokens. Nearly 25% of students chose to save their tokens rather than redeem immediately, demonstrating the financial literacy outcomes the program was designed to promote. The platform met all client objectives for accessibility, stability, security, fraud detection, and regulatory compliance.
Can blockchain technology be used for government financial inclusion programs?
Yes. The San Luis, Argentina case demonstrates a replicable model. AccelOne's Billetera Activa uses a private blockchain to issue and manage government-backed digital tokens with fully auditable transactions, restricted access controls, MFA, biometric validation, and KYC compliance, meeting the security and regulatory requirements of government financial programs while remaining scalable to new user groups and programs.
