摘要： The present disclosure provides a photonics-aided vector terahertz signal communication system. The system includes an optical frequency comb generation module, a vector terahertz signal generation module, an optical fiber transmission module, a vector terahertz signal detection module, and a vector terahertz signal emission module that are sequentially connected, where the vector terahertz signal generation module includes a first binary sequence generator, a first electronic amplifier, and a first intensity modulator that are sequentially connected, the first binary sequence generator generates binary data representing to-be-transmitted data, the first intensity modulator performs, based on the binary data, amplitude modulation on an optical frequency comb entering the first intensity modulator, and an optical signal obtained after the modulation of the first intensity modulator is a vector terahertz signal carrying the to-be-transmitted data. In the present disclosure, a vector terahertz signal can be generated by using an intensity modulator.

摘要： The present disclosure discloses a distributed consensus algorithm and apparatus for rapidly generating a block. The algorithm includes: broadcasting a new transaction to all nodes (S110); collecting, by each of the nodes, the new transaction into a block (S120); evaluating a trust value of each of the nodes to obtain an evaluation result (S130); selecting honest miners according to the evaluation result (S140); obtaining negotiation rules (S150); creating, by the honest miners, a new block according to the negotiation rules, and broadcasting the new block to all the nodes (S160); and when all transactions in the nodes are valid but do not take effect, receiving the new block and adding the new block to a blockchain (S170).
