Delta (product website) describes an integrity layer or "network of networks" intended to enable developers to add blockchain-like guarantees (verifiable rules, auditable outcomes, settlement guarantees) to existing web backends without rewriting those backends into smart contracts. The stated goal is to enable teams to maintain existing stacks (languages, APIs, databases, CI/CD) while Delta provides a settlement and verification layer with cryptographic proofs and a shared ledger for assets and accounts.
Delta's documentation presents a two-layer model:
- Domains: independent execution environments (implemented as web services) where applications run and users transact.
- Base layer: a shared state machine that secures assets and validates state updates from domains according to global rules ("global laws") plus optional domain-specific rules ("local laws").
Vendor documentation describes the following integration and UX characteristics:
- Integration via a Gateway and an OpenAPI connector intended to avoid rewriting backend logic into smart contracts.
- Asynchronous proof generation intended to preserve application responsiveness while settlement finality occurs later.
- A privacy model described by the vendor in which inputs, state, and code remain on the developer's server; only proofs and public outputs are posted to the network.
- The vendor states there are no gas fees and that passkey authentication is integrated, presenting an experience closer to conventional web applications than wallet-centric crypto UX.
