# 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.
