Blockchain is essentially a distributed storage system. Because it adopts a transaction bookkeeping storage model, it can also be called a distributed bookkeeping system.
1. Distributed collaboration
The blockchain requires all or part of the designated nodes in the chain to cooperate to confirm transactions and jointly maintain the blockchain network. The signature technology based on asymmetric encryption ensures that all transactions and certifications on the chain can be traced back to achieve reliable distributed collaboration of data.
2. Difficult to tamper with
Because of the special chain data structure of the blockchain and the data storage method in which all nodes have all transaction records, tampering with historical records requires at least half of the nodes to pass the verification. It is difficult for anyone to modify the data on the chain.
3. Enforcement
The smart contract code is written into the blockchain following the block generation process, which ensures the reliability and openness of the contract. When the conditions of the smart contract are triggered, the contract content will be enforced according to the specific code logic.
4. High scalability
Since blockchain nodes do not rely on any central organization or node, as long as there is one node running, the blockchain network is still running. At the same time, the cost for new participants to access the blockchain network as a new node is low, and there are almost no restrictions. The entire blockchain network has high scalability.
Blockchain + copyright protection, I think it can be summarized from three aspects: confirmation of rights, use of rights, and protection of rights.
1. Confirmation
In the confirmation of rights, the original creator saves his work to the blockchain through a certain product, calculates the hash value of the original work, and uploads it to the chain with a timestamp. In this way, your work will have a unique mark, and the hash value of the work will be synchronized to all nodes on the face of the block. The right can be confirmed through the principle of “whoever creates first, who goes online first, and who first authenticates”, and can even completely record all the changes in a work from the initial creation to the final presentation.
Second, right to use
Blockchain technology can be used to build a copyright trading platform, and the transfer of the right to use works will be tracked. The transaction process is transparent, open and traceable, so that the value of digital content of content creators can be reflected.
3. Rights protection
If there is unauthorized reprinting or misappropriation, evidence collection is required.
Therefore, the introduction of blockchain technology can indeed greatly improve the operational efficiency of intellectual property services, solve the long and complicated problems of the intellectual property industry from the three links of confirmation, use and protection of rights, and provide a perfect solution for copyright protection.
