Chain, a provider of blockchain technology solutions, on Monday released Chain Core Developer Edition, a free and open source version of its distributed ledger platform that enables organizations to issue and transfer assets on permissioned blockchain networks.

Visa recently said it is working with Chain to build a new platform to give financial institutions a secure and fast way to process business-to-business payments globally.  The platform, Visa B2B Connect, uses Chain Core, an enterprise blockchain infrastructure that facilitates financial transactions on scalable, private blockchain networks.

Building on this technology, Visa is developing a new near real-time transaction system designed for the exchange of high-value international payments between participating banks on behalf of their corporate clients, the company said.

According to Chain, this is the first time developers can download and install Chain Core to start or join a blockchain network, build financial applications, and access in-depth technical documentation and tutorials.

Users have the option to run their prototypes on a test network, or “testnet,” operated by Chain, Microsoft, and the Initiative for Cryptocurrencies and Contracts (IC3), a collaboration of Cornell University, Cornell Tech, UC Berkeley, University of Illinois at Urbana-Champaign, and the Technion, said Chain.

“Chain Core Developer Edition provides a seamless end-to-end experience to design, build, and test prototypes on a system we created from the ground up to suit the scalability and security requirements of the financial industry,” said Ryan Smith, CTO of Chain.
