Introduction to Corda
A Corda Network is a peer-to-peer network of Nodes, each representing a party on the network. These Nodes run Corda applications (CorDapps), and transact between Nodes using public or confidential identities.
When one or more Nodes are involved in a transaction, the transaction must be notarised. Notaries are a specialised type of Node that provides uniqueness consensus by attesting that, for a given transaction, it has not already signed other transactions that consumes any of the proposed transaction’s input states.
