US Patent 10135607 Distributed ledger interaction systems and methods

Distributed public ledger interaction methods and systems are presented by which one or more elements of a first smart contract are privately recorded on a secure ledger node. In some variants the first smart contract is executed so as to retrieve public ledger node data from a first public ledger node so as to configure at least one transaction that is thereafter executed at least to the first public ledger node or to a second public ledger node (or both).
