Bigchaindb

BigchainDB is an open-source blockchain database that combines the developer experience and query power of a database with blockchain properties: decentralized (Byzantine fault-tolerant) control, immutable append-only data storage, and built-in support for registering and transferring assets. Developed by BigchainDB GmbH (Berlin) with the IPDB Foundation overseeing the software and public networks, it exposes a simple versioned HTTP API on each node (default port 9984) for creating and reading transactions, assets, outputs, metadata, blocks and validators. Applications sign transactions with Ed25519 crypto-conditions, so authorization is enforced at the payload level rather than via transport authentication. Official Python, JavaScript and Java drivers are published, and the maintained continuation of the codebase is the Planetmint project.

Bigchaindb publishes 7 APIs on the APIs.io network, including Assets API, Blocks API, Metadata API, and 4 more. Tagged areas include Company, Crypto, Blockchain, Database, and Decentralization.

Bigchaindb’s developer surface includes documentation, getting-started guide, engineering blog, and 15 more developer resources.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 80 points between them, because the conditional facet above carries the other 20. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 80% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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/bigchaindb: open an issue to ask a question, or submit a pull request to add artifacts.
