A computer-implemented method (100) and system (1) for controlling the performance of a smart contract. The method includes storing a contract on or in a computer-based repository. The contract is associated with a licence between a first user (U1) and a second user (U2). The method further includes receiving, over a communications network, a transaction comprising a transfer of a token from an agent (A) to the first user (U1) or the second user (U2). The transaction comprises metadata that includes an identifier indicative of a location where the contract is stored. The method further includes querying a peer-to-peer distributed ledger (i.e. blockchain) to determine whether the transaction comprises at least one unspent output (UTXO). The method further includes, responsive to querying the peer-to-peer distributed ledger, determining whether to modify performance of the contract. The blockchain may be the Bitcoin blockchain.

This disclosure relates to a method and device for processing cross-blockchain transactions. The method includes: acquiring a cross-blockchain transaction processing request from the source blockchain network by the first interface node, and distributing the cross-blockchain transaction processing request to the first number of relays; performing a first verification and a signature on the cross-blockchain transaction processing request by the relays to generate sub-signatures; generating a first signature of the relay system by the signature aggregation node after obtaining a second number of sub-signatures; and transmitting the cross-blockchain transaction processing request and the first signature to the target blockchain network.

Systems, apparatus, and methods for transacting, recording, validating and/or verifying agricultural products and its proceeds. The 2018 Farm Act rescinded industrial hemp from Schedule I of the Controlled Substances Act (CSA). Although industrial hemp has a variety of uses, the Government's biggest concern is the ingestion of tetrahydrocannabinol (THC) and cannabidiol (CBD). Commercial regulation typically balances a variety of factors: e.g., consumer protection, regulatory overhead, market competition, tax revenue, public policy, etc. In contrast, law enforcement has a singular purpose, and may go to extraordinary lengths to stop criminal activity. Various embodiments described herein provide a blockchain ledger-based supply chain that allows many commercial and regulatory entities to independently cooperate. Every transaction is permanently and transparently recorded within a chain-of-custody; the chain-of-custody enables a traceability; transitive linkages enable regulatory compliance. A variety of new applications are enabled by the blockchain ledger-based supply chain.

The disclosed technology is generally directed to a distributed query-and-command system. In one example of the technology, in a trusted execution environment (TEE) of a first node, database code of the first node and distributed ledger code of the first node is executed, such that execution of the distributed ledger code of the first node instantiates a first instance of a distributed ledger of a consortium blockchain, and such that execution of the query-and-command code of the first node instantiates a first instance of a query-and-command system. The consortium blockchain is distributed among a plurality of nodes, and the query-and-command system is distributed among the plurality of nodes. A first transaction that is associated with modifying the query-and-command system is received. The first transaction is executed. Changes associated with the first transaction to the distributed ledger are persisted.
