VanityBlocks are regular nfts, who's mint transaction takes
up a whole ETH block, meaning there aren't any other transactions in that block!
In addition to wasting lots of ETH on fees we only mint blocks that have pretty numbers, like
14114114, 14360063, 14401440....
You can think of ETH blocks as train rides, each train ride has a number, the first one was #0, the next #1, currently we're around #15,000,000,
when you send someone eth, mint an nft, trade an nft or sign some blockchain related transaction, that transaction is only vaild == "in the blockchain"
when that transaction has "ridden" a specific train ride, there are a limited amount of seats in each train, usually around 200-300 transactions "ride" it.
When we mint vanityblocks, we buy up all the tickets on a specific train ride with a pretty number say 14401440, and mint just 1 nft with it.
So the collector can kinda "own" the train ride
Think of ETH Blocks as pages in the New York Times newspaper, if you want to send someone eth, buy an nft, etc..., you have to buy a small ad on some page of the news paper,
so that everyone can see that you sent your eth to the recepient, so that your transaction can be finalized, what we do is buy up a whole page ad in this "newspaper",
and mint an nft with it, so you can kinda "own" this whole page forever
Also, all the ad pages are numbered and we buy up only ones that have pretty numbers like
14114114, 14360063, 14401440....
