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.
