Blockchain technology is valuable in every aspect and is useful for everyone. The major use case advantages are mentioned below.
- For Supply chain management - Ensures traceability and cost-effectiveness.
- For Quality Assurance - Can detect irregularities in supply chain thus helps execute prompt corrective actions.
- For Accounting - Guaranteed accuracy of records and highly traceable audit trail.
- For Smart Contracts - Eliminates need of mediators saving time and money.
- For Voting - Removes electoral fraud.
- For Stock Exchanges - Can cut down intermediaries, (Clearing Houses) speed up process, saves considerable time and Money.
- For Energy Supply - Can accurately track usage and can help track clean energy.
- For Peer to Peer Global transactions - Enables fast, secure and cost-effective fund transfers across the world.
- Transparent Economies - All these processes will result in minimizing corruption, Forced & Improved utilization of allocated funds across every sector/ organization including Governments, resulting Increased per capita income and overall global growth.
These are all use cases, not an explanation of how value is created
The main value comes by limiting the human involvement in transactions/processes which takes considerable time whereas with blockchain technology big transactional volumes can be validated automatically.
That makes a lot of sense. However all use cases you described are run by it systems as well, so how do blockchains actually create these efficiencies since they are arguably less efficient than centralized systems.
Right now, Blockchains are most efficient technology available as it automates the transactions and processes. Blockchains creates Trust, accuracy and consistency most efficiently. Spreading wrong perception of inefficiency will not work for long. Because most of the categories in every segment is already covered in different countries. The only area where government is directly involved is taking more time since you need specialized brains and governments willingness/preparedness to cover, example; Nasa, security, Voting, Military and others.
again u are selling features instead of explaining the value creation
Blockchains create efficiencies by lowering the cost, improving the record keeping and by enabling complete transactional traceability.
