1. A UAV (unmanned aerial vehicle) logistics operation and air traffic control method based on blockchain technology, comprising functions to receive an aerial transport order, arrange a UAV flight, make airway planning and submit an application for flyable airspace to an ATCC (air traffic control center) for approval, and carry out a flight mission by a UAV pilot and characterized in that: Each of an ATCC, a UAV pilot and a flight in an airway is taken as a node and a variety of information for UAV, flight and airway is recorded with a blockchain infrastructure for creation of a block;A plurality of waypoints are planned for an airway and a distance between two waypoints is defined as a flight segment wherein a block related to a waypoint passed by a flight will be broadcasted to other participating nodes on the blockchain network in which a waypoint just passed by and/or a next waypoint to be passed by the flight and/or another flight and a block consisting of timestamps are recorded such that air traffic status of all flights in an airway and availability of a flight segment are added into broadcasted information of the blockchain network for data consistency among all participating nodes;An ATCC monitoring real-time service conditions of an airway for appropriate traffic control optimizes availability of an airway, ensures a safe separation distance between flights and collision prevention, and avoids events jeopardizing air safety such as malicious invasion, tampering, hacker's hijacking or illegal manipulation. 2. The UAV logistics operation and air traffic control method based on blockchain technology as claimed in claim 1 wherein the blockchain infrastructure is a permissioned blockchain infrastructure. 3. The UAV logistics operation and air traffic control method based on blockchain technology as claimed in claim 1 wherein a block for a flight should be signed with a private key of the ATCC and re-encrypted with a public key of the flight, which is encrypted with a private key of the flight for data consistency between nodes. 4. The UAV logistics operation and air traffic control method based on blockchain technology as claimed in claim 1 wherein a block consists of (a) a block header comprising version number, records of a previous block, path-segment tree root nodes and timestamps and featuring a fixed size and (b) a block body comprising registered UAV electronic ID certification, detailed information for an airway and a flight, labels for a departure point and a destination of a flight segment in a current block, information of a completed flight segment and timestamps. 5. The UAV logistics operation and air traffic control method based on blockchain technology as claimed in claim 4 wherein the block body further comprises generated time, hash of a referred reply, index tag of a reply record, coordinate of a departed waypoint, coordinate of an arrived waypoint, times of completed replies in a flight segment, digital signature of a reply, record size and protocol version. 6. The UAV logistics operation and air traffic control method based on blockchain technology as claimed in claim 1 wherein a procedure for each flight mission comprises steps as follows: Information of each waypoint passed by a flight is first broadcasted to other participating nodes on a blockchain network;Several unverified hashes for flight status are collected in a block by all nodes such that the block comprises multiple flight status;A node to encrypt flight status is decided based on a protocol;A node which is granted the authority to encrypt flight status and complete encryption early will broadcast a new block to other participating nodes;The new block is verified by and connected to all nodes;All flight status is authenticated completely. 7. The UAV logistics operation and air traffic control method based on blockchain technology as claimed in claim 1 wherein a transaction procedure for a UAV flight in a relevant blockchain comprises steps as follows: An ATCC launches a flight mission of a UAV flight for an airway in order to process encryption with a public key produced by the private key of the UAV flight that owns a detailed UAV electronic ID tag for a block wherein an instruction for a flight mission, which is unapproved or tampered and detected during verification, is neither written into a block nor executed;The instruction for a flight mission is sent to the UAV flight for broadcasting a new transaction to all participating nodes;The flight mission of the UAV flight is enabled and a calculated hash is written into a block for the UAV flight after the instruction for the flight mission is verified as a correct and non-tampered instruction;The calculated hash is broadcasted to all nodes, each of which will initiate a write-in step for completion of a block and data consistency;The instruction correctly written into a block is verified, decrypted by the private key of the UAV flight and received;The UAV flight in a flight mission broadcasts its real-time position and a token for relevant data, for example, a waypoint was passed or a previous flight segment safely passed is available, to all nodes according to previous steps for encryption/decryption operated repeatedly. 8. The UAV logistics operation and air traffic control method based on blockchain technology as claimed in claim 1 wherein multiple blockchains of different airways are connected with one another in series to create a blockchain inside another blockchain for B2B scenarios such as communications, transactions or liquidations between UAV transportation task management systems operated by different organizations. 9. The UAV logistics operation and air traffic control method based on blockchain technology as claimed in claim 1 wherein flight status of a UAV flight having passed a waypoint is broadcasted to other members on the network through a token with which safe barrier-free flight segments to be passed are known to other UAV flights and several available flight segments that have been passed are released for update of the token. 10. The UAV logistics operation and air traffic control method based on blockchain technology as claimed in claim 1 wherein several air channels are developed in an identical flight segment by planning an airway in airspace based on the concept of pipeline, both a constant UAV flying speed and a safe separation distance between UAVs as required are set according to a blockchain-based node reply mechanism, and multiple UAV flights are arranged in different air channels inside an identical flight segment simultaneously or deployed at front and rear ends of an identical air channel for optimum utilization of an airway. 11. The UAV logistics operation and air traffic control method based on blockchain technology as claimed in claim 10 wherein planning and design of an airway depends on defined flight parameters, which comprise a safe width of an air channel, a basic length of a flight segment, a required safe separation distance, a UAV flight speed, a blockchain mechanism, etc. attributed to a modeling resolution, to derive a mechanism optimizing an UAV flight speed and a safe separation distance for maximum utilization of an airway and safe air traffic.
