The blockchain is essentially a distributed database plus a set of integration systems. In 2013, our view of bitcoin is that Nakamoto has created an unrepeatable Internet. The blockchain guarantees that data cannot be tampered with, which is the most essential. In the blockchain, the data is open, and whoever send a coin to others can be seen by everyone and so the transaction cannot be denied.
But at present, the blockchain is more difficult to execute blockchain in the real world project. Give an example of milk traceability. I shipped a box of milk from Beijing to Tianjin. If I have already written it on the blockchain, but I actually have a car accident on the road, what should I do if the milk turns over? Every link in real life is likely to have problems. The data on-chain and off-chain the blockchain is difficult to get through. The perfect blockchain is not reliable right now.
If the blockchain is to be commercialized, I think three infrastructures are needed to be established.
First, there is a high performance public blockchain to execute the application;
The second, there are stable coins that can be accepted by ordinary merchants;
The third, the blockchain user identity system can be traced and supervised.
I personally feel that before the implementation of these three infrastructures, the blockchain implement to real world is basically a joke.
By connecting the parts that need to be anchored within and outside the chain to the regulatory and stable currency, the blockchain can achieve the unification of the chain and the external data, and problems can be received in the real world.
At present, most of blockchain projects will be highlighted, but in fact the blockchain is still not available. Really landed like Mobai, ofo, everyone can see it when they look up. At present, the blockchain industry has at least RMB 100-200 billion to enter the market. Is there a implement? Did not implement. It doesn't make sense to implement the blockchain only in the concept.
