Provenance

Provenance Blockchain is a public, proof-of-stake blockchain purpose-built for financial services and the tokenization of real-world assets. Built on the Cosmos SDK with CometBFT consensus, it exposes its functionality through first-party modules including marker (token/marker issuance), metadata (asset registry and the p8e contract execution environment), exchange (on-chain order book), ledger, name, attribute, hold, trigger, and msgfees/flatfees. Applications integrate over the public Cosmos REST (LCD / gRPC-gateway) API at api.provenance.io, gRPC, and Tendermint RPC at rpc.provenance.io, and via first-party SDKs (Go, Kotlin gRPC client, Rust/CosmWasm provwasm bindings, and JavaScript wallet libraries). HASH is the native staking and gas token. The chain, protobuf data model, and SDKs are open source under the provenance-io GitHub organization.

Provenance publishes 1 API on the APIs.io network. Tagged areas include Company, Blockchain, Financial-Services, Tokenization, and Real World Assets.

Provenance’s developer surface includes documentation, API reference, getting-started guide, support, changelog, authentication, and 13 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/provenance: open an issue to ask a question, or submit a pull request to add artifacts.
