Dear @peter-k ,
Thank you for participating in this Mini Crypto program, I really appreciate your good intentions and your efforts in understanding our practice this time.

• You didn't mention how a block works and how the data we write in the block becomes valid or invalid.

• You are understand about blockchain, but you didn't explain it detail.

• This learning will greatly benefit you to be in Crypto Academy later, because we are in cryptocurrency-based social media, and Cryptocurrency is in blockchain technology.

• Thank you very much, we will waiting for your next exercise, and we will waiting you at the season 4 of Crypto Academy. 👍💪
