The blockchain

Infrastructure for
the AI era.

TOS is an open-source Layer 1 with a masterchain, shardchains, native TVM contracts, post-quantum validator authentication, and a shielded native-asset implementation.

What the chain makes possible.

AUTHORITY

Authenticate consequential actions

Validator signatures authenticate consensus. Account contracts define who may act, under which limits, and how authority changes.

VALUE

Transfer and settle value

Native TOS pays network fees and funds contracts. Shielded notes add a defined privacy layer; escrow contracts implement explicit settlement rules.

STATE

Coordinate shared state

Contracts maintain deterministic account state. Messages connect accounts across shards, and validator certificates authenticate accepted chain history.

Why blockchain for agents?

Autonomous programs need durable identities, enforceable budgets, deterministic contracts, and verifiable settlement. TOS brings these requirements into the account and execution model.
