Cambridge Blockchain

Cambridge Blockchain, Inc. was a blockchain-based digital identity and compliance software company founded in 2015 and headquartered in Cambridge / Boston, Massachusetts.

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.
