Hello @anyagladys,
Thank you for taking interest in this class. Your grades are as follows;

The following caught my attention:

Genesis block is also known as block 0.

Right but in some blockchains it is referred to as Block 1.

The first block was mined by an anonymous developer called Satoshi Nakamoto, containing 50 bitcoins and it took him 6days to accomplish the process in 2009.

Not really. It took 6 days to mine Block 1 after Block 0 was mined.

is untradable Because it doesn't contain any transaction

The reason why those coins are untradeable is unknown for now.

000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f

This is the hash of the block and not a hex code.

Feedback and Suggestions

• You really need to try and understand the topic better so you would be able to express yourself better. Some statements were really difficult to understand.

• Always double check your work so you don't contradict yourself when writing.

• Some valuable information is missing on the Bitcoin Genesis Block while some are irrelevant.

• Pay attention to your paragraphs always.

Thanks again as we anticipate your participation in the next class.
