Blockchains progress one block at a time. The data these blocks contain is based on the data that previous blocks have. This is what makes them in essence chained to one another, and this function allows us to understand with a degree of certainty that the transactions we make, can be made. In other words, without data from previous blocks you cannot verify whether or not the funds that are being transacted can be transacted and have not been spent already. This applies to all blocks in the Bitcoin blockchain, except for one: the Genesis Block.
The First in the Chain
Satoshi Nakamoto designed the Genesis Block to be hard coded into Bitcoin’s software. This block anchors basically all the other blocks in the chain, and has 1073 transactions that were sent to it, but the block has no previous reference in the chain. It is the only block in the blockchain that does not require data from a previous block to be validated because it is hard coded in the software, but its rewards cannot be spent due to what is described by the Bitcoin wiki as a “quirk in the way the Genesis Block is expressed in the code.”
The next block in the chain came only 6 days after Satoshi mined the Genesis Block. Since blocks in the Bitcoin chain are set to be released more or less every 10 minutes, there are 3 main theories that explain the delay according to Bitcoin’s wiki:
- One theory sustains that Satoshi released the Genesis Block, conducted some tests for 6 days, erased the test blocks and then mined the second block in the chain.
- The second theory sustains that it took 6 days to mine the next block due to low hash rates on the blockchain.
- Another theory sustains that Satoshi was inspired by the January 3rd, 2009, headline in The Times of London and back-dated the time stamp on the Genesis Block to match that headline.
The Times Headline and Bitcoin’s Message
Given that Satoshi designed Bitcoin to overcome many of the shortfalls of fiat currency, including fractional banking, it would be fitting to time stamp the Genesis Block on January 3rd, 2009. On that day, The Times’ headline was “Chancellor on brink of second bail out for banks.” Nakamoto included this headline in the coinbase parameter of the Genesis Block, probably as a declaration of what Bitcoin was intended to be, but it is highly unlikely that his timing was so perfect.
Therefore, the theory that sustains that the time stamp on the Genesis Block was back-dated, has some credibility. After all, this was the first block in the chain, so it would have been easy to manipulate that time stamp. The symbolism of the launch date given the headline on The Times on that day is regal.
What is the Significance of Bitcoin’s Genesis Block?
There is no doubt that the Genesis Block is like no other block in the blockchain. It is technically different than subsequent and symbolically significant for anyone who is looking for an alternative to the fiat monetary system. The Genesis Block ushered in a new era for money, international trade, distributed data systems and many other industries or sectors in the economy.
