The 'Practical Application' of Blockchain

A residential community in Shenyang has 66 locks on its gate, hailed as the 'cheapest access control system': each lock corresponds to a car owner, and one can only enter or exit by using their own key to unlock it.

Car owners jokingly refer to it as a self-made 'simplest blockchain'! Key features:

✅ Decentralized: No need for centralized management

✅ Traceable: One lock per person

✅ Immutable: Each lock corresponds to a specific owner

Saving money and effort, and no fear of parking space theft!

This is the clearest understanding I have had of blockchain...
