The live broadcast acquisition terminal comprises but is not limited to related equipment capable of acquiring live broadcast contents, such as a mobile phone, a computer, a PAD (PAD application program), a VR/AR (virtual reality/object distance) camera and the like, the selection of the live broadcast acquisition terminal is not limited by the above list of the embodiment of the application, and the equipment with the function of acquiring the live broadcast contents can be selected for use. The preprocessing in the second live content formed after the first live content is preprocessed comprises but is not limited to encoding and packaging operations, and optional schemes can also be splicing and the like to realize direct conversion of video streams or processing processes of live content which can be viewed by a user; it should be noted that, when the preprocessing process is encoding and packaging, that is, links with relatively high requirements on computing power, such as video splicing, are moved to cloud processing, so as to reduce the requirements on processing power of the acquisition-side device. At the moment, the acquisition end does not perform video splicing, but transmits the original video shot by the VR camera to the cloud end for splicing. Through a 5G network communication protocol and by utilizing a 5G wireless network, the data transmission delay is reduced, and the user experience is improved.
The main chain adopts POW algorithm consensus, realizes decentralization, and ensures that live content data is safely and reliably stored and is not easy to be attacked to cause data loss and the like; the branch chains are in consideration of running speed, a POS or DPOS algorithm with high consensus speed is adopted, cross-link communication is carried out between the main chains, between the branch chains and between the main chains and the branch chains through an API gateway protocol, the API gateway protocol accelerates the cross-link data transmission speed, data are processed in a high-concurrency mode, the response speed of DAPP applications such as intelligent contracts on the main chains and the branch chains is increased, live content uploading experience is guaranteed, and time delay is reduced.

As an optional implementation manner of this embodiment, the second transaction is one of a non-asset transaction or an asset and non-asset mixed transaction. An asset transaction refers to the occurrence of a transaction accompanied by the transfer of asset value, such as Token, virtual value carrier, etc. Non-asset transactions refer to the occurrence of transactions accompanied by the uplink storage, exchange, modification, etc. of data information to ensure that the uplink data is not tampered with. The mixed transaction of assets and non-assets refers to the occurrence of transaction, which is accompanied by the uplink, exchange, modification and the like of data information, and the transfer of asset value, such as Token, the transfer of virtual value carrier and the like. For a first data packet or a second data packet, the types of information carried by the first data packet or the second data packet are different due to different types of the first transaction or the second transaction, and when the first transaction or the second transaction belongs to an asset transaction, the first data packet or the second data packet comprises asset value transfer data, such as Token and virtual value data transfer information; when the first transaction or the second transaction belongs to a non-asset transaction, the first data packet or the second data packet includes data information which needs to be uplink stored, exchanged, modified and the like, such as an evidence uplink for preventing data tampering, a copyright uplink and the like; when the first transaction or the second transaction belongs to the mixed transaction of assets and non-assets, the first data packet or the second data packet comprises asset value transfer data and data information needing uplink storage, exchange, modification and the like, and uplink storage, exchange, modification and the like of data can be carried out while value transfer is carried out. Namely, when live broadcast content is uploaded, the commercial application scene can be expanded along with the transfer of asset value, and the method has high economic popularization value.
As an optional implementation manner of this embodiment, the branched chain is a public chain, a union chain, or a private chain; and the branched chains are communicated with each other in a cross-chain mode through an API gateway protocol.

as an optional implementation manner of this embodiment, the branched chain is provided with a programmable intelligent contract, and the intelligent contract adopts an API interface. The programmable intelligent contract arranged on the branched chain can expand the application range and the field of the branched chain, and can quickly receive data through the API interface.

The edge node receives a second transaction, broadcasts the second transaction, utilizes one of three data types which can be processed by edge calculation, namely image object data, the second transaction belongs to the image object data, the second transaction comprises a second data packet, the second data packet comprises first content and a result of encrypting the first content by combining an AES encryption algorithm and a Hash algorithm, after the edge node receives the second transaction, the edge node analyzes the second data packet, utilizes the AES encryption algorithm and the Hash algorithm to combine the encrypted calculation result of the first content according to the first content and compares the encrypted calculation result with the encrypted result in the second data packet, if the encrypted calculation result is consistent with the encrypted result in the second data packet, the edge node passes verification of the second transaction, after a plurality of second transaction passes verification, the second transaction is packaged into a second block, the second block is broadcast between the edge nodes on the branched chain, after the verification passes, the second block is sent to the main chain to be packaged and commonly identified, and after the commonly identified is, the second block, the second transaction, the second data packet and the first content are stored in the cloud, the first content is spliced and encoded and pushed to form live content.
As an optional implementation manner of this embodiment, the second transaction is created by using a ring signature or a zero-knowledge proof method. And the security is increased, compared with multiple signatures, the signature mode of the ring signature or zero knowledge proof method does not influence the speed of creating the second transaction, and the time delay is reduced.
