比特币的减半是一种重复，在这种周期性的重复中，比特币的符号身份得到改变。用黑格尔的话，比特币的概念作为主体能动地演进。在每一次减半之后，“比特币是什么”这样命题宾语也在发生改变。

对比特币的认可和比特币的这种重复是相伴相生的。对比特币认可的人往往经历过对它的误认

齐泽克对历史中的重复的解读很有启发，在重复中，事件改变了其符号身份。当它第一次发生时，它被体验为偶然性创伤，体验为某个非符号化的入侵。

只有通过重复，这一事件的符号必然性才会得到认可，即在符号网络中找到自己的位置。可以说，对事件第一次出现的误认，直接构成对它的最终认可

基于Nostr的网盘存储🤯🤯

quoting note1l2h…jaqs

While I was in Mediera with all the other awesome people at the first SEC cohort there where a lot of discussions around data storage on nostr and if it could be made censorship-resistent

I remember lots of discussions about torrents, hypercore, nostr relays, and of course IPFS

There were a few things I learned from all these conversations:

All the existing solutions have one thing in common. A universal ID of some kind for files

HTTP is still good. we don't have to throw the baby out with the bath water

nostr could fix this... somehow

Some of the existing solutions work well for large files, and all of them are decentralization in some way. However none of them seem capable of serving up cat pictures for social media clients. they all have something missing...

An Identity system

An identity system would allow files to be "owned" by users. and once files have owners servers could start grouping files into a single thing instead of a 1000+ loose files

This can also greatly simplify the question of "what is spam" for a server hosting (or seeding) these files. since it could simply have a whitelist of owners (and maybe their friends)

What is blossom?

Blossom is a set of HTTP endpoints that allow nostr users to store and retrieve binary data on public servers using the sha256 hash as a universal id

What are Blobs?

blobs are chunks of binary data. they are similar to files but with one key difference, they don't have names

Instead blobs have a sha256 hash (like b1674191a88ec5cdd733e4240a81803105dc412d6c6708d53ab94fc248f4f553) as an ID

These IDs are universal since they can be computed from the file itself using the sha256 hashing algorithm ( you can a files hashing on linux using: sha256sum bitcoin.pdf )

How do the servers work?

Blossom servers expose four endpoints to let clients and users upload and manage blobs

GET /<sha256> (optional file .ext)

PUT /upload

Authentication: Signed nostr event

Returns a blob descriptor

GET /list/<pubkey>

Returns an array of blob descriptors

Authentication (optional): Signed nostr event

DELETE /<sha256>

Authentication: Signed nostr event

What is Blossom Drive?

Blossom Drive is a nostr app built on top of blossom servers and allows users to create and manage folders of blobs

What are Drives

Drives are just nostr events (kind 30563) that store a map of blobs and what filename they should have along with some extra metadata

An example drive event would be
{
  "pubkey": "266815e0c9210dfa324c6cba3573b14bee49da4209a9456f9484e5106cd408a5",

  ]
}
There is a lot going on but the main thing is the list of "x" tags and the path that describes the folder and filename the blob should live at

If your interested, the full event definition is at github.com/hzrd149/blossom-drive

Getting started

Like every good nostr client it takes a small instruction manual in order to use it properly. so here are the steps for getting started

1. Open the app

Open https://blossom.hzrd149.com

2. Login using extension

You can also login using any of the following methods using the input - NIP-46 with your https://nsec.app or https://flare.pub account - a NIP-46 connection string - an ncryptsec password protected private key - a nsec unprotected private key (please don't) - bunker:// URI from nsecbunker

3. Add a blossom server

Right now https://cdn.satellite.earth is the only public server that is compatible with blossom drive. If you want to host your own I've written a basic implementation in TypeScript github.com/hzrd149/blossom-server

4. Start uploading your files

NOTE: All files upload to blossom drive are public by default. DO NOT upload private files

5. Manage files

Encrypted drives

There is also the option to encrypt drives using NIP-49 password encryption. although its not tested at all so don't trust it, verify

Whats next?

I don't know, but Im excited to see what everyone else on nostr builds with this. I'm only one developer at the end of the day and I can't think of everything

also all the images in this article are stored in one of my blossom drives here

通过Mostr好像可以关注长毛象用户，但是不知道长毛象用户能不能看到Nostr用户的回帖。

Nostr不是VPN，抗审查的点主要在于人说自己想说的话并“可以”被传播出去，相比于中心化平台的禁言销号有质的不同。

当然墙还在那里，对大部分人来说通往Nostr的路还是给断了。
