Linux Foundation Decentralized Trust Lab

A currency of
expertise.

Learning Tokens turns the learning process itself into verifiable credit. Every unit of competence — attendance, a score, an act of help — is minted on-chain the moment it happens, not certified years later at graduation.

The thesis

Learning happens in steps. So should its recognition.

  1. 01

    Recognition arrives too late

    A degree summarises years into a single line. The partial efforts — the assessment passed, the concept mastered, the peer helped — leave no durable trace anyone can verify.

  2. 02

    Skills are the missing unit

    Learning Tokens records competence at the granularity it actually happens, tagged with standard fields of knowledge (CIP) and skills (WEF Reskilling Revolution taxonomy).

  3. 03

    The learner owns the proof

    Each token is a portable, tamper-evident credential the learner holds — threadable across curricula, institutions and borders, without asking a registrar for permission.

The instruments

Four tokens, one taxonomy

Two templates built on the InterWork Alliance Token Taxonomy Framework: a non-fungible formula for attendance and scores, and a fungible formula for help.

Non-fungible

Attendance for Learners

Proof of presence to acquire a unit of competence. Minted by the instructor once the learner’s attendance is confirmed — the first link in the chain of engagement.

Non-fungible

Score for Learners

The value of acquiring a competence, awarded against the scoring guide. Metadata records the field of knowledge, the skill, and the course, instructor and institution IDs.

Fungible · ERC-20

Help for Learners

Recognition of collaborative support — answering forum questions, reviewing peers, grading together. Fungible by design, so help can be exchanged for waivers, scholarships and standing.

Non-fungible

Score for Instructors

Learners assess teaching performance at set points in a course. Feedback becomes a credential for the instructor, closing the loop between teaching and outcomes.

Scoring guides act as the oracle — the transparent grading policy that authorises every mint and transfer.

The lifecycle

From institution to verifier, in five moves

01

Institution

Registers on Learning Tokens and receives a verifiable institution ID — the root of trust for everything minted beneath it.

02

Instructor

Is registered by the institution, then registers a course with its fields of knowledge (CIP) and skills (WEF taxonomy).

03

Course

Publishes a scoring guide: the transparent policy of points available at each step. This guide is the oracle.

04

Learner

Enrols, attends, is assessed and helps peers. Each recognised act mints a token transferred to the learner’s wallet.

05

Verifier

Any employer or institution reads the learner’s tokens directly from the ledger — no phone call to a registrar required.

The bridge · ltsdk

Plug in the LMS you already teach on

The Learning Tokens SDK connects your existing Learning Management System to the protocol. It unifies authentication, pulls course and grade data, and shows it in a dashboard so your team can review everything before any token is issued.

Credentials never leave your machine — the SDK stores them locally and keeps them out of git and the published package.

OAuth consent flow

$ npm install ltsdk

✓ access key verified
✓ auth server   → localhost:5002

Under the hood

An open, modular stack

Every layer is open source and independently runnable — deploy to a local Hardhat node in minutes, or to a permissioned enterprise network.

Smart contracts

Solidity · Hardhat

LearningToken contracts define the mint and transfer rules for every token template.

Backend

NestJS · TypeScript

Registers institutions, instructors and courses; orchestrates minting against scoring guides.

Dashboard

React · Vite · Tailwind

The console where teams review LMS data and issue tokens to learners.

SDK

ltsdk · npm

The LMS bridge and local review dashboard that runs on the implementer’s machine.

Network

Hyperledger Besu · Quorum

Runs on a local EVM node, a testnet, or a permissioned Besu / Quorum network.

Talent Angels

If Learning Tokens mints the proof of skills, Talent Angels helps you navigate them. One agentic AI — Graph-RAG over the world’s occupational taxonomies — that owns your goal end to end: reads the intent, plans a route, and answers with evidence and confidence. Built by the same mentorship lab under LF Decentralized Trust.

One assistant · four navigation skills

Locate

Free text to a precise point on the map, with confidence.

Connect

Neighbors, hierarchy and gaps around any point.

Pathfind

Routes between two points, under the rules you set.

Evaluate

Score and rank those routes by a documented policy.

Skills are the currency of talent

One assistant plans, then dispatches its skills — no maze of hand-off agents. Determinism lives in the graph tools; the model decides what to ask and how to answer, over a living ontology of talent.

Built by four cohorts of mentees

Learning Tokens has been a mentorship Lab since 2022. Every line below is someone who spent a term of the Linux Foundation mentorship program building part of this protocol — and whose own skills, fittingly, are recorded in the ledger they helped write.
