The digital asset authentication platform 2 It is a node of blockchain public chain 5;

Specifically, the blockchain public chain 5 includes several public chain nodes 51, and the digital asset authentication platform 2 is a node on the blockchain public chain 5. Because the blockchain network has the characteristics of decentralization and has the effect of non-repudiation, the digital asset certification platform 2 as the node of the blockchain public chain 5 can ensure the credibility of the data in the digital asset certification platform.

The client 11 is configured to perform the following steps:

The authentication request is sent to the digital asset authentication platform 2. The authentication request includes the digital asset to be authenticated or the digital asset entity to be authenticated and the authentication code.

In one scenario, the buyer wants to purchase the seller's digital asset, but the buyer needs to authenticate the digital asset or digital asset entity provided by the seller in order to determine the authenticity of the digital asset or digital asset entity. In general, the seller sends the digital asset to be authenticated or the entity and the authentication code to the buyer, and the buyer sends an authentication request with the digital asset to be authenticated or the entity to be authenticated and the authentication code to the digital asset authentication through the client 11 Platform 2. The digital asset authentication platform 2 subsequently processes the authentication request, and finally obtains the authentication result. Therefore, it can be understood that, in the embodiments of the present application, the expression of the term "authentication" includes "confirmation".

The digital asset authentication platform 2 is configured to perform the following steps: receiving an authentication request; specifically, the digital asset authentication platform 2 receives an authentication request sent by the client 11.

Specifically, a digital signature operation is performed on the digital asset to be authenticated or the digital asset entity to be authenticated in the authentication request, and the digital signature operation uses the same algorithm and algorithm parameters as the digital signature operation for obtaining the signature string A.

Compare whether the signature string A and the signature string B are the same. If they are the same, the digital asset to be authenticated or the digital asset entity to be authenticated is successfully authenticated, indicating that the digital asset or digital asset entity provided by the seller is true; if it is not the same, it is to be authenticated The digital asset or digital asset entity to be authenticated fails to be authenticated, indicating that the digital asset or digital asset entity provided by the seller is fake. The digital asset authentication platform 2 sends the authentication result to the client 11.

The client 11 is configured to perform the following steps:

As shown in Figure 10, if it exists, obtain the digital asset or the signature string A of the digital asset entity in the digital asset package summary;

According to the signature string A, the digital asset to be authenticated or the digital asset entity to be authenticated is authenticated, and the authentication result is sent to the digital asset authentication platform;

If it does not exist, according to the authentication code, through the dedicated sub-chain agent node 4, search the digital asset package summary 6 in the blockchain public chain 5, if found, obtain the digital asset or the signature of the digital asset entity in the digital asset package summary String A;

According to the authentication code, the dedicated sub-chain proxy node 4 searches for the digital asset package summary in the public blockchain connected to the dedicated sub-chain. The specific process is: as shown in Figure 11, if the digital asset package summary 6 is stored on the blockchain public chain, and the authentication code is passed, the digital asset package summary can be found; as shown in Figure 12, if the digital asset package summary 6 is stored On the sub-chain nodes of other dedicated sub-chains, it is impossible to find the digital asset package summary 6 in the blockchain public chain 5. At this time, further in the blockchain public chain, query and store the target dedicated sub-chain of the digital asset package summary 6 , And then search the corresponding private sub-chain through the public node of the blockchain public chain and the target private sub-chain to obtain the digital asset package summary 6.

According to the signature string A, the digital asset to be authenticated or the digital asset entity to be authenticated is authenticated, and the authentication result is sent to the digital asset authentication platform.

The process of obtaining the digital asset or the signature string A of the digital asset entity in the digital asset package summary is the same as the process in Embodiment 3, but the execution subject is different. Embodiment 1 uses a digital asset authentication platform, and this embodiment uses digital assets. Agent platform 9.

In a possible implementation manner, the digital asset agency platform 9 is further configured to perform the operation of authenticating the digital asset to be authenticated or the digital asset entity to be authenticated according to the following steps:
