A community of Shenyang tell you what is Block chain with 32 locks

In order to prevent unregistered vehicles from occupying the parking space of the community, this residential area in Shenyang has 32 locks into chains for one gate, and each owner has issued a key to let themselves open their own lock. In the community, each lock has a corresponding number.

Someone teased: Isn’t this the blockchain.

It seems to be correct, I can’t refute it.
