Society
Build a chain worth keeping. The runtime, the pallets, and the governance are open to contribution - and the people who put their time in shape what ships next.
Why contribute
Five reasons a serious developer invests time in Taler.
Open development
Open by design. The runtime, the pallets, and the contracts are auditable and forkable.
On-chain governance
Any holder can propose a referendum. Votes are weighted by conviction and recorded on-chain - approved calls execute through the runtime.
Engineering depth
Rust, Substrate, WebAssembly, Schnorrkel/sr25519 signatures, BLAKE2-256 hashing. Substance over surface.
Influence the runtime
Your contribution becomes the protocol that other developers build on.
Forkless evolution
Improvements ship through governance, without splitting the community or the codebase.
Where you fit in
Five paths into the network, each with a different way to shape what ships.
Developers
Build runtime pallets, ship ink! contracts, contribute to client libraries. Every commit lands in the open repository, every PR is reviewed in public.
Validators
Run nodes, take part in consensus, secure the network. Operational depth backed by bonded TAL, with liveness tracked through heartbeat messages and slashing on prolonged unresponsiveness.
Researchers
Audit security, model economics, propose protocol improvements. Findings flow into Democracy referenda - the strongest arguments ship.
Educators
Write tutorials, run workshops, onboard new contributors. The first developer reading the docs deserves the second one's help.
Designers
Improve developer experience, refine documentation, shape the brand language that carries across the ecosystem.
Governance
Membership is participation.
Anyone can propose. Holders vote. The runtime executes the result on-chain.
Democracy lets any stakeholder propose a change. Referenda use coin-weighted voting with conviction multipliers - longer locks deepen the vote. The Council, elected every seven days, cancels dangerous referenda and approves Treasury spending.
The Technical Committee handles urgent and emergency situations: it can move a proposal to a three-day fast-track vote or block a malicious motion before it reaches a referendum. The Treasury, funded by 80% of every transaction fee, finances ongoing development.

Engineering choices that protect the network also protect the planet.
Nominated Proof of Stake replaces energy-hungry mining with deterministic validator election. Six-second blocks and weight-metering keep computation efficient by design.
Fewer wasted cycles. Lower hardware demands. A smaller energy footprint than mining-based chains. The same engineering rigor that makes Taler fast also makes it responsible.
Where the network goes next is up to who shows up.
Builders, validators, researchers, educators - every layer of Taler grows through the people who put their time in.
The codebase is open. Governance is on-chain. The path to your first contribution is one walk-through away.
