Make any blockchainmore secure

Discover the Fern protocol

How it works


Many blockchain networks are controlled by a single or small group of entities. This renders them exposed to a Sybil attack, where nodes, or the people controlling them, act, collude or bribe, to undermine the integrity of the blockchain ledger and defraud users.

Fern protocol

Fern makes any blockchain network more decentralised and secure by connecting identified node and oracle providers through an anonymous protocol. Fern combines enterprise compliance requirements with trustless network fundamentals.

Pictogram trust

Anonymous selection and connection to blockchain protocol network: trustless

Live demo

Once a blockchain application network has connected with independent providers of nodes and oracles, they’ll be able to view all activity from their dashboard.
