# Blockchain sucks

For some reason I don't understand many people started to think that
"Web3 is the future", "blockchain is going to solve all your
problems", "blockchain is going to give us privacy..."

## But what is blockchain?

A blockchain is a (an append only) glorified [Linked
list](https://en.wikipedia.org/wiki/Linked_list), in which, to insert
something, you have to pay rent to some "miner".

## But it's decentralizated!

No, it is not, everyone has the same blockchain, if someone decides
that you are an idiot, the fact that you're an idiot will be
replicated on all the nodes, which is no different from going banning
you from a Minecraft server. What is decentralizated is the idiocy of
cryptobros.

Also, it is not decentralizated: [This
website](https://www.bitcoinera.app/arewedecentralizedyet/#) shows the
stats for cryptocurrency decentralization. 

## But is going to give us privacy!

1. Get my bitcoin address (bc1q59t6z2lqdve7tfu3nc56dkh9djvpzpxllwyek6)
2. Paste it in <https://blockstream.info> (Bitcoin's blockchain explorer)
3. There you have every transaction I have ever made, how much money i
   have and shit.
   
There is no way to delete something from a blockchain, once it was
recorded, it is going to be there until the last node on earth powers
itself off.

## But you can't censor anything on a blockchain!

Even is that was true, [I2P](https://i2p.net),
[Freenet](https://freenetproject.org), and many other project, can
accomplish the same without blockchains and shit.

## But we can have personal websites with the .eth thing!

Neocities exist, and you can do exactly the same thing (and, again, in
a sane way, with [I2P](http://geti2p.net/en/faq#addresses))

## But information can be stored eternally in the blockchain

We already had bittorrent, a protocol in which, to participate, you
don't have to fetch the entire blockchain.

## Conclusion

I don't expect any cryptobro to understand half of this article.
