Abstract: Systems, devices, and methods for cross-chain interoperability protocol privacy are disclosed for privately transferring cross-chain transactions from a source chain to a destination chain. Transfer of information and/or assets between blockchains is encrypted and decrypted, leading to improved functionality and privacy for each respective chain.

Abstract: A system and method for providing a randomness function to a smart contact on a decentralized network. An oracle receives a request for at least one random value to be supplied to a smart contract executing on a decentralized network, the request including a seed. The oracle generates the at least one random value based on the seed, and a secret key associated with the oracle, wherein the oracle is identified on the decentralized network by a public key associated with the secret key. The oracle generates a cryptographic proof based on the at least one random value and the public key and sends the at least one random value and the cryptographic proof to the decentralized network, whereby the proof, and thus the randomness of the at least one random value, can be verified.

Abstract: A system and method for providing a randomness function to a smart contact on a decentralized network. A decentralized oracle network receives a request for at least one random value to be supplied to a smart contract executing on a decentralized network, the request including a seed. The oracle network generates the at least one random value based reports from a verified quorum of oracle nodes of the oracle network. The oracle network broadcasts a report including a randomness function to the smart contract.

Abstract: A system and method in which a network of offchain oracle nodes are used to provide dynamic information to consuming smart contracts in a decentralized computing environment. The off-chain oracle network and a corresponding protocol reduces the likelihood of damage from rogue oracles acting in concert. Periodically, the oracle nodes, jointly and in concert, run the protocol to sign a report containing observations from many of the oracles in the network. The report is transmitted to a smart contract C running on a DLT. The smart contract C can validate the report, pay each oracle node that contributed an observation to the report and expose the median, or other calculated value, of the reported values to the on-chain consuming smart contracts.

Abstract: Systems, methods, and storage media for implementing a secure state machine implemented as computer logic in a networked computing environment are disclosed. Exemplary implementations may: generate a public key/private key pair for each of multiple participants respectively; provide a switch parameter for the state machine; specify time parameters for reporting, by an offchain oracle, the value of the switch parameter; and specify terms for reporting, by the offchain oracle, the value of the switch parameter to executable logic recorded on the distributed ledger. The executable logic making payment to pseudonymous wallet addresses associated with the keys in response to a value of the switch parameter received from the off-chain oracle.
