Problems solved by technology

[0004] If a large amount of information is stored on the blockchain, the storage space on the chain will expand, and the performance of the entire blockchain will decrease. Therefore, asset information registration services cannot be provided in the existing technology

Embodiment 2

[0050] Embodiment 2: From step S201 and step S202 of Embodiment 1, it can be known that after generating the asset custody on-chain request information, the asset custody system first signs the asset custody on-chain request information, and then sends it to the asset application terminal system for signature. Finally, a double-signature asset custody on-chain request information is formed. Similarly, the asset application terminal system can first sign the asset custody on-chain request information, and then send it to the asset custody system for signature, and finally form a double-signed asset custody on-chain request information. The above-mentioned two steps of embodiment one can be replaced by following process:

[0051] (1) The asset custody system generates asset custody on-chain request information based on off-chain asset custody transfer request information and custody asset issuance information, and then sends it to the asset application terminal system.

Embodiment 3

[0054] Embodiment 3: The digital asset storage systems in Embodiment 1 and Embodiment 2 both realize lightweight storage of information, and the custody asset storage information stored in the digital asset storage system can be verified through tamper-proof information to prevent other tampered with. There are many ways to obtain the anti-tampering information, and the verification process of each way is different, and the following descriptions will be made according to the different ways.

[0055] For the case where the tamper-proof information is the hash value obtained by hashing the custody asset storage information, the specific implementation of the verification process is as follows:

[0056] (1) The asset custody system obtains the corresponding custody asset preservation information from the storage service system according to the custody asset registration index identifier of the custody asset registration index information;

[0057] (2) The asset custody system p...

Embodiment 4

[0062] Embodiment 4: The digital asset storage system in Embodiment 1 realizes the lightweight storage of information. When subsequently querying the storage information of custody assets in the digital asset storage system, it is necessary to first query the custody assets in the initial block in the asset ledger system. Asset description information, and then query the custody asset preservation information based on the custody asset registration index identifier in the custody asset description information. The specific implementation is as follows:

[0063] image 3 It is a schematic diagram of the main flow of information query by the blockchain-based digital asset storage system in Embodiment 4 of the present invention. Such as image 3 As shown, the main flow of information query in the blockchain-based digital asset storage system of Embodiment 4 of the present invention includes the following steps:

[0064] Step S301: The asset application terminal system generate...

Abstract

The invention discloses a blockchain-based digital asset storage system and method, and relates to the technical field of digital assets. A specific implementation of the system includes: the asset custody system generates custody asset preservation information and sends it to the storage service system; the storage service system receives and stores the custody asset preservation information, and then feeds back the custody asset registration index information with the signature of the storage service system to the asset custody system; the asset custody system sends the custody asset issuance request information with the signature of the asset custody system to the asset ledger system; the asset ledger system verifies the custody asset issuance request information, and after the verification is passed, the custody asset issuance request information record contains In the initial block information of the asset account book address of the asset owner. This implementation saves the custody asset preservation information to the off-chain storage system, saves the custody asset registration index information to the on-chain asset ledger system, and realizes the lightweight storage of on-chain information.

Description

technical field [0001] The present invention relates to the technical field of digital assets, in particular to a blockchain-based digital asset storage system and method. Background technique [0002] At present, blockchain technology is developing rapidly. As a new decentralized computing paradigm, blockchain provides technical support for the operation of various digital assets on distributed networks. These digital assets run on the distributed network of the blockchain, do not rely on a specific third party or central party to keep accounts, but conduct global multi-node consensus accounting through shared ledgers, and achieve a technical guarantee through encryption algorithms security system. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] If a large amount of information is stored on the blockchain, the storage space on the chain will expand, and the performance ...
