9-year-old Bitcoin Concept, Looking Back at the First Block in the Blockchain Chain

This article examines 9-year-old Bitcoin Concept, Looking Back at the First Block in the Blockchain Chain. It presents the main facts, practical implications, and key points in a clearer, easier-to-follow format.

Today is the Genesis Block 9th anniversary, the first block in the bitcoin chain. Since the advent of virtual currency, so many changes have been made, and this first block is the starting point for the bitcoin chain on the way to becoming a revolution in peer-to-peer sharing.

What Is Genesis Block?

Genesis Block is the first Bitcoin block, or primitive block, with hash code.

Later, it was called block 0 but it was previously counted as block 1. Genesis Block is especially in that there is no reference to the previous block. Below is an illustration of this block in a comment about the old version of Bitcoin. The first paragraph is the necessary variables to recreate the block. The second paragraph is the block in the standard printblock format, containing the data collapsed from the previous paragraph.

This block comes with the text ' The Times 03/Jan/2009 Chancellor on brink of second bailout for banks. ' (a sentence in a British Times article) probably used as evidence that this block was created. on January 3, 2009 as well as commenting on unrest due to the bank's proportional reserve.

Genesis Block

At that time, (in 2009) the GPU digging was probably not used, but it must be around 2011. The first Google Trends reference for 'GPU mine Bitcoin' started in April 2011.

So Satoshi probably dug on the CPU. But exactly how much CPU did you use to dig this first block?

Satoshi's version 0.1 source code does not have a special cycle or command to dig Genesis Block. In fact, it is straightforward (hardcore) which means creating from another software with no source code. Moreover, because the BTC at that time was also worthless, there was no competition between the diggers, so it could be assumed that Satoshi dug on his own (and only one) computer.

Satoshi's Computer

In 2009, a good CPU could perform about 2 caps of 22 hash pairs per second (double-hashes/second). If two microprocessors are used, there will be 2 threads to dig. Satochi's 0.1 client is not optimized for dual hashing (by backing up, restoring the intermediate state of the second hash application).

What computer does Satoshi use to dig the first block?

According to calculations, after only 6 days, there is only 17% chance that he will find Genesis Block. So is he lucky or deliberately digging for 6 days? Compare the time of Block 0 and Block 1:

Block 0: 2009-01-03 18:15:05 Block 1: 2009-01-09 02:54:25 (6 days later)

Although the average time between blocks is 10 minutes, the time between block 0 and block 1 is 6 days. Someone thought that Satoshi had worked with bitcoin before but deliberately released it on the right day according to the content of the newspaper, then continued to dig up the Genesis Block that used hours in the past. It may also be due to slow hashing so he spends 6 days digging with the same timestamp before switching to block 1.

The Reward for Being Trained by Genesis Block

The first 50 BTC to be delivered to the address. 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa, although it cannot be used. It is unclear whether this is unintentional or intentional but Genesis Block received 1073 transactions with more than 16 BTC added. Nobody knows why the reward for Genesis Block digging is not available, but bitcoin and all its derivative products also have an initial bonus that is not possible. The total amount of bitcoin circulated cannot exceed 21 million BTC.
