What is Genesis block or primary block in Blockchain?

The Genesis block is the first block recorded in each Blockchaink. This block is also known as block 0 or sometimes block 1. Genesis Block is also called “Genesis Block”.

Since there is no other block to refer to before the first block, the genesis block is placed in the Blockchaink with hardcode.

In the Bitcoin blockchain, the first blockchain was created on January 3, 2009. The reward for this block was 50 bitcoins, which will not be spent forever. This block does not contain any transactions.

Each bitcoin block contains information about the transactions made in that block. But these blocks also contain other data; Previous block hash. For example, block number two, in addition to transaction information, also contains hash block number one, so that all blocks are connected like a chain; That’s why we call this technology blockchain. But before block one, no block is generated that hash is used in block one. For this reason, Satoshi Nakamoto has created the number zero block or Genesis block itself as a hard code.

Hidden message Satoshi

In Genesis Block Bitcoin, Satoshi wrote a message that is forever recorded in history. In the coinbase parameter, along with the usual block data, the following message was inserted, which is one of the headlines of the Times:

January 3, 2009: The Treasurer [سلطنتی انگلستان] On the eve of the second financial assistance to banks.

Times Magazine;  Issue for January 3, 2009
Times Magazine; Issue for January 3, 2009

This message was probably inserted as a timestamp to prove that the block was not created before January 3rd. However, the chosen headline is also strongly related to the original cause and purpose of bitcoin creation.

Communication with religious texts

Genesis has a special place in all religions and the process of creation of the world is explained in the form of this concept. Nomination for the first block in the Blockchain is also related to this issue. Also, the second block (block number 1) in the Bitcoin Blockchain was registered exactly six days after the first block.

  • Block 0: 03-01-2009
  • Block 1: 09-01-2009

The cause of the break is unknown at this time, but the hypothesis is that Satoshi was either resting for the past six days or intending to relate those six days to the story of the creation of the Bible in the six days. سازد. The second scenario is more likely.
