This section introduces the origin and development of blockchain
Now answer the question of the previous section

Now start this section:
The origin and development of blockchain
In the knowledge course I studied, the development of blockchain technology to the present is divided into three periods and a coveted future period
They are the 1.0 era, the 2.0 era, the 3.0 era and the future era
These periods are now described separately
1. Blockchain 1.0: Encrypted Digital Currency
Bitcoin was born after the 2008 financial crisis
2. Blockchain 2.0: Smart Contracts
3. Blockchain 3.0: Enterprise Applications
4. Blockchain 4.0: The Future
Let us blockchain people work hard with hope and make it happen one day in the future!
The same small thought question:
Which of the following statements about blockchain is true
- A: Ethereum is an open source blockchain platform that supports smart contracts
- B: Bitcoin is an encrypted digital currency

- D: We can develop blockchain applications based on Ethereum
The answer is revealed in the next section, and the content of this section is over.
