The fourth major feature of blockchain assets is that they cannot be copied. The so-called non-replicability means that you cannot send a 1BTC copy to someone else, and you still have this 1BTC, which is a double flower problem. The Bitcoin blockchain is mainly used by miners to verify that the transaction input exists in UTXO and the timestamp to deal with the "double flower" problem.
Not only is Bitcoin difficult to copy, but other data that exists on the blockchain is difficult to copy.
On the information Internet, information ownership is difficult to guarantee, and all visible information uploaded to the Internet can be copied and distributed at will. The data that exists in the blockchain relies on cryptography to ensure the security of data transmission and access, and the ownership of the information belongs to the producer of the information.
For example, you can upload your personal consumption preference data to the blockchain for data trading. Only the authorized entity can have the right to view or use all/part of the data. Who can see the data, completely by you Decided that the ownership of the data is still in your hands.
This advantage can be effectively applied to copyright protection, helping to solve the current problem of difficult to prove and difficult to prove. Original works (text works/audio/video, etc.) are time stamped when uploaded to the blockchain. The record of "Who created what works" will send a copy to the entire network and cannot be tampered with.
All records of the use of this work will be recorded in the blockchain in detail, transparent and open. Once someone tries to tamper with the copyright certificate record, it will be found different from most other honest nodes. To facilitate effective proof. Of course, the premise is that cooperation with the judicial appraisal agency is required to ensure that the copyright certificate registered on the blockchain is legally binding.
Non-replicability is an important factor in ensuring that it becomes an asset.
