Cambridge Blockchain

Cambridge Blockchain, Inc. was a blockchain-based digital identity and compliance software company founded in 2015 and headquartered in Cambridge / Boston, Massachusetts. Its enterprise platform let financial institutions deliver strong digital identities to end users while meeting KYC/AML and data privacy obligations (including European GDPR), giving individuals control over their own personal identity data shared across institutions. The company was backed by investors including Partech and PayPal, and was acquired by Blockchains, Inc. in December 2020, after which its team and identity technology were folded into Blockchains' digital identity product. The former company website (cambridge-blockchain.com) is no longer served; the surviving public developer surface is its GitHub organization and two first-party npm cryptographic libraries. No public HTTP API, OpenAPI specification, developer portal, or hosted documentation was ever published.

Cambridge Blockchain is profiled on the APIs.io network. Tagged areas include Company, Financial-Services, Digital Identity, Blockchain, and KYC.

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