Chain is a cloud blockchain infrastructure that enables organizations to build better financial services from the ground up. The chain launched Chain Core, a permissioned and open-source blockchain, and Sequence, its ledger-as-a-service offering. Customers can receive discounts and pay business fees through chain tokens (XCN), and participate in community protocol governance and access advanced features.

Chain has launched the chain improvement proposal CIP-007, which will implement a series of changes to the chain protocol, including token burning, time lock expansion and so on. The proposal also calls for renaming Chain Protocol to Onyx Protocol, Chain DAO to Onyx DAO, and Chain Token to Onyxcoin, using the same XCN code
