Federated Blockchain

A federated blockchain is a permissioned distributed ledger where governance and validation authority are shared among a predetermined group of organizations rather than being fully decentralized or centrally controlled. In this model, a consortium of trusted entities collectively maintains the network, approves transactions, and makes protocol decisions. Federated blockchains combine elements of both public and private systems: they offer greater transparency and security than centralized databases while maintaining control over who can participate in consensus. This approach is particularly suited for industry collaborations where competing organizations need to coordinate on a shared infrastructure while maintaining some degree of autonomy and trust. Example: Hyperledger Fabric is a prominent federated blockchain framework where multiple organizations such as banks, supply chain partners, or healthcare providers can form a consortium. Each organization operates nodes that validate transactions, and the network requires agreement from a subset of these federated members to finalize blocks, rather than requiring approval from all participants or a single central authority. Why it matters for blockchain technology: Federated blockchains enable enterprises to gain blockchain benefits without surrendering all control, making them ideal for B2B applications requiring regulatory compliance, auditability, and coordinated governance among industry participants who need predictable consensus mechanisms.
