Abstract: A transaction ordering system and method for sequencing transactions processed by a decentralized network in which nodes communicate with a peer-to-peer protocol to process transactions for the exchange of value in the form of main chain assets. Transaction sequencing is accomplished by an auxiliary decentralized network including multiple oracle nodes communication through a peer-to-peer protocol, wherein the auxiliary decentralized network does not store value in the form of mainchain assets and wherein the auxiliary decentralized network is configured to; receive a set of transactions to be executed by the decentralized network; create, based on a predetermined policy, ordering information indicating a sequence in which transactions in the set of transactions are to be processed; and transmit the ordering information to a mempool of decentralized network for execution of the transactions, by the decentralized network, in the sequence.

Abstract: Systems, devices, and methods provide for smart contract automation for triggering smart contract functions. The smart contract automation may receive log data, provide an upkeep payload to a workflow, the upkeep payload comprising one or more active upkeeps. The smart contract automation may determine, by the proposal workflow, whether the one or more active upkeeps is an eligible upkeep. The smart contract automation may determine, by the smart contract automation system, a reportable result based on the eligible upkeep and the log data. The smart contract automation may transmit the reportable result to a blockchain.

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.

Abstract: Systems, methods, and storage media for interfacing at least one smart contact stored on a decentralized architecture with external data sources are disclosed. Exemplary implementations may: receive service level information from a user; publish, by an on-chain order-matching contract, a log representing the required attributes; receive, by the on-chain order-matching contract, bids from plural external data sources based on the log of the required reputation attributes; and select, by the on-chain order-matching contract, more than one of the plural external data sources as selected data sources and notifying the selected data sources, whereby the selected data sources can be used collectively to provide information requested by the at least one smart contract.
