Description

technical field [0001] The present invention relates to the technical field of traceability of physical property right assets of the Internet of Things, specifically a blockchain-based traceability system of physical property right assets of the Internet of Things. Background technique [0002] The digital economy is booming, and more and more traditional industries are transforming to digital. In the traditional way, the manufacturing industry represented by factory processing, or the agriculture represented by farm planting, both use physical objects as outputs. In the process of circulation and sales of physical items, their value is easy to measure, that is, the value of an item refers to its use value, which can be stipulated in the sales contract. [0003] As an important part of fixed assets, the orchard’s output (fruit) use value is easy to realize, that is, the annual output can be directly sold to obtain income, but because the fixed asset (plant itself) is within...

However, the buyer cannot track the change process of the fixed asset throughout its life cycle. The method of purchasing fixed assets at a discounted price in the current period is equivalent to opening a blind box.

The digital certificate can only prove the existence of the transaction and its source can be traced, it is difficult to prove the real-name identity of the creator of the digital certificate, and whether the creator himself authorizes the assets to be digitally uploaded to the chain
