For an enterprise, there is a need to effectively manage the fixed assets in the warehouse, in use and in transit, and improve the utilization rate of the fixed assets, thereby improving the profit level of the enterprise.
At present, in the fixed asset management of enterprises, fixed asset accounts are often established, fixed assets are checked on time or at any time, and some enterprises also stick or install bar codes, radio frequency identification tags or smart cards on the fixed assets to master the conditions of the fixed assets at any time and perform fixed asset and optimized configuration inside the enterprises so as to obtain higher fixed asset utilization rate.
Although the fixed asset account is established by enterprises in a paper and electronic mode, the paper account is easy to lose, be modified and the like, and the electronic account existing in a computer database and the like is also easy to be modified and deleted artificially. Under the condition that the fixed asset is lost, stolen or damaged, if the specific standing book of the fixed asset is not available, the use condition of the fixed asset is difficult to trace, and responsible personnel are specific.
The blockchain is a distributed, public, transparent, trusted book containing the complete records of transactions since the system began to run. Since all transactions must be recorded on the blockchain, the trader needs to sign the transaction for verification and accept supervision from other personnel. The block chain is public to all related personnel, and supports to check all data of the block chain at any time; once the transaction is recorded in the blockchain, the data cannot be tampered and deleted, or cannot be tampered and deleted at great expense, unless more than half of the relevant personnel permit it.
