Fern makes any blockchain network more decentralised and secure by connecting identified node and oracle providers through an anonymous protocol. As many blockchain networks are controlled by a single or small group of entities, this renders them exposed to a Sybil attack ? the nodes, or the people controlling them, can easily influence the entire network through colluding or bribing. Sybil attack undermines the integrity of the blockchain ledger and defrauds users, which contradicts the value of blockchain being trustless and secure. Fern addresses this issue by combining enterprise compliance requirements with trustless network fundamentals.
