Fern adds security and trust to decentralised application networks. Fern provides decentralisation as a service. Our goal is to allow any blockchain to add security and trust to their network by providing access to a community of identifiable, yet anonymous, node and oracle providers. Blockchains that require additional, independent nodes and oracles can request them from the Fern community. These third-party nodes from Fern provide the additional decentralization that can allow members of limited-node networks to be trusted and applications to grow.
