Onyx (formerly Chain) is a cloud-based blockchain infrastructure that helps organizations build improved financial services from the start. Chain previously released Chain Core, a permissioned, open-source blockchain, along with Sequence as its ledger-as-a-service offering. With Onyx Core, institutions can set up and run a blockchain network or join an expanding set of other networks that are changing how assets move globally. The Onyx Protocol lays out the rules for how assets are issued, sent, and governed on a blockchain network. It enables either one entity or a coalition of organizations to operate a network, accommodates multiple kinds of assets, and is compatible with other standalone networks. Onyx Core is built to meet the performance requirements of modern financial environments, with transaction creation, signing, and validation taking place in milliseconds.

Sequence is a ledger-as-a-service designed to let organizations securely monitor and transfer balances in token form. With Sequence, organizations can manage their financial assets as tokens on private ledgers and, soon, transfer them smoothly across public networks.

Users can get discounts and cover commercial costs using Onyx Tokens (XCN), while also taking part in community protocol governance and unlocking premium features.
