The company announced on its blog:
The library is available as an NPM and Bower package, and encapsulates all the logic necessary to work with Openchain, including transaction serialization in protocol buffers format and signing. The library relies on Bitcore for signing and key management given that Openchain uses the same cryptography as Bitcoin.
The Coinprism development team has also rewritten the Openchain wallet to make use of that new library.
Openchain, which Coinprism describes as a “transaction chain”, is a distributed ledger but not literally a blockchain. It does not group transactions into blocks but instead links transactions to the chain as soon as they are submitted to the network. As a result, Openchain is able to offer real-time confirmations, and the reason it is dubbed a “transaction chain”.
