Federated Trust Model

Definition ∞ A Federated Trust Model is a security arrangement where trust is distributed among a select, pre-approved group of entities rather than being fully centralized or entirely open. These chosen entities collectively validate transactions, maintain the system, or perform specific governance functions. It offers a middle ground between permissionless and fully centralized systems, providing some decentralization with controlled access.
Context ∞ This model is often employed in permissioned blockchains or hybrid systems that seek a balance between efficiency, control, and a degree of distributed authority. Discussions frequently revolve around the transparency, accountability, and selection process of the chosen federators. Its suitability depends on the specific use case and the required level of trust distribution.
