Quorum

Founded by J.P. Morgan, Quorum is an enterprise-focused version of Ethereum. It modifies Ethereum’s core and therefore, can incorporate the Ethereum updates seamlessly and quickly. Similar to Ethereum, Quorum is also open-source and free to use the blockchain platform in perpetuity. Unlike other blockchain platforms, it uses vote based and different algorithms to process hundreds of transactions per second. Designed to be permissioned, the networks using Quorum won’t be open to everyone. It can handle applications requiring high throughput processing and speed of private transactions.
