Authenticate consequential actions
Validator signatures authenticate consensus. Account contracts define who may act, under which limits, and how authority changes.
The blockchain
TOS is an open-source Layer 1 with a masterchain, shardchains, native TVM contracts, post-quantum validator authentication, and a shielded native-asset implementation.
Validator signatures authenticate consensus. Account contracts define who may act, under which limits, and how authority changes.
Native TOS pays network fees and funds contracts. Shielded notes add a defined privacy layer; escrow contracts implement explicit settlement rules.
Contracts maintain deterministic account state. Messages connect accounts across shards, and validator certificates authenticate accepted chain history.
Autonomous programs need durable identities, enforceable budgets, deterministic contracts, and verifiable settlement. TOS brings these requirements into the account and execution model.
