It is known in the world of the blockchain that the blocks that make up the blockchain carry transaction details and fees, as well as the ability to write notes and messages on them.

Yesterday, Ethereum 2.0 was launched, starting the first phase of the expansion upgrade on the world’s second largest blockchain by market capitalization.

While the launch was as planned and without issues, except for one surprising thing.

In the first block, a message was written that no one understood at first.

Instead of honoring the launch of Ethereum 2.0 for the first time, or targeting and monetizing banks as has been the case in previous writings on Bitcoin blocks, the message carried by the first block of the Ethereum 2.0 blockchain was a little more exotic.

she was the message bear the following phrase:

Mr. F was here.

What does this message mean? And who is Mr. “F”?

At first, some thought this was a reference to the popular TV series “Arrested Development” because it was the name of the fifth episode of season three.

In an episode of the series, no one knows who Mr. “F” is, until it is revealed that it is an inappropriate acronym.

But it turns out that the naming of Mr. “F” in the Ethereum 2.0 blockchain is completely different.

Mr. “F” is named after the nickname “Fahrenheit” who had the honor of writing his name on the first Ethereum 2.0 block.

Surely you are now asking, and who is Mr. Fahrenheit?

Mr. Fahrenheit is a decentralized application (dapp) developer, who was one of the prominent and veteran developers in the development of the Ethereum ecosystem prior to his move to the Tron Blockchain.

In January 2019, Mr. Fahrenheit was running Team Tron Shrimp, which created a game and decentralized app called Tron Shrimp Farm, on the Tron blockchain.

The game was popular for a brief period, as its number of users rose to more than 31,671 users in a single day but it is no longer as active as before.

Before the launch of Ethereum 2.0, Fahrenheit noted and wrote the following:

Does that mean I’m in block 0 or 1?

Mr. Fahrenheit was then asked on Discord if the writing on the block indicated that he had stopped developing.

And he answered:

No, it’s short for “Mr. Fahrenheit” as in the Queen’s Song.

And if you look at the signature of “Vitalik Buterin” it is an acronym for “Mr. Farrenheit” instead.

Mr. Fahrenheit then posted a photo of the signature in question as shown in the tweet above.

So, simply put, the letter “F” published in the first block of Ethereum 2.0 refers to Mr. “Fahrenheit” in recognition of his contributions to the development of Ethereum.
