Bitfury Group is a blockchain technology company founded in 2011 as one of the earliest Bitcoin mining hardware makers and full-cycle infrastructure providers, and now operating as a technology incubator headquartered in London with data-center and hardware operations behind Bitcoin transaction processing. Its developer-facing surface is Exonum, the open-source (Apache-2.0) framework Bitfury Group Limited built for private and permissioned blockchain applications: an Exonum node exposes REST and WebSocket endpoints through its explorer service, system API plugin, supervisor and time-oracle services, and ships light clients for JavaScript, Python and Java plus a Rust crate family, a node CLI and published Protobuf message definitions. Bitfury also anchors permissioned chains into the Bitcoin blockchain and incubates Cipher Mining, Crystal, LiquidStack and Axelera AI.
