Welcome to the Jörmungandr User Guide.
Jörmungandr is a node implementation, written in rust, with the initial aim to support the Ouroboros type of consensus protocol.
A node is a participant of a blockchain network, continuously making, sending, receiving, and validating blocks. Each node is responsible to make sure that all the rules of the protocol are followed.
Jörmungandr refers to the Midgard Serpent in Norse mythology. It is a hint to Ouroboros, the Ancient Egyptian serpent, who eat its own tail, as well as the IOHK paper on proof of stake.
