While Nostr and AT Protocol (used by Bluesky social) may appear similar on the surface, there are subtle differences between them.

Nostr can be seen as a self-contained protocol where relays are capable of implementing their own content moderation policy and store only the content that users have transmitted to the relay.

It is the clients that implement their own User Interface and algorithm.

Conversely, the Authenticated Transfer Protocol (AT Protocol) is intended to serve as the underlying protocol for multiple social networks (applications).

Using AT Protocol, each application can implement its own user interface and content moderation, but the data is held in the users' own data repository.

Additionally, users will be able to select the algorithm used to surface content. These competing algos will be available in a marketplace.

Similarities:

- Both are protocols

- Both are open source

- Both utilise public key cryptography for identity

- Both are used to enable a social network experience

Differences:

Data storage -

Nostr users transmit data (notes) to relays who store these notes.

AT Protocol users have a Data Repository, which applications can request access to read.

This Data Repository stores content, such as:

- Identity

- Profile

- Social graph

- Content (posts, comments, likes, media blobs, etc.)

This data is saved locally on your laptop / phone, depending on available storage, and is .

Key Rotation -

Nostr uses a simple pub / priv key pair for authentication. It does not natively support key rotation.

If the private key is compromised, the user cannot easily revoke access to the compromised key.

AT Protocol natively supports a root private key (Recovery Key), which is used to authorise a signing key.

If the signing key is compromised, the user can issue a new signing key using their Recovery key.

Moderation -

Nostr relays and/or clients are able to implement their own moderation policy.

Relays and/or clients may(?) be responsible for compliance and takedown requests.

Applications built on top of the AT Protocol are able to implement their own moderation policy and are responsible for takedown requests, however this data would still exist in the users Personal Data Repository.

Account Portability -

Competing social networks (think Instagram, Facebook, and Twitter) can use the AT Protocol to request access to this data, which is controlled by the user.

This makes account portability possible, meaning it would be possible to login to competing social media platforms, with their own interfaces, features and moderation policies, but still retain your contacts and supported content.

So who is the winner?

Based on my (extremely limited) understanding of both, AT Protocol is more complex but is superior from a user data, key management and algorithm selection perspective.

The Personal Data Repository structure allows users to store their data and authorise or revoke access to this data by applications.

Additionally, users are able to rotate keys in the event that their signing key is compromised and select the algorithm used to surface content.

他这前半段我很同意。

最后一段太打消我学哲学的积极性了，不同意，反对😡

绝大部分人的知识差距并不需要到拼智商程度，

反而学习的兴趣、方法和毅力更重要。

比如相对论、欧拉公式、傅立叶级数、偏微分方程、线性代数、群论基础知识等，完全理解这些浅显的数学概念并不需要太高智商。

普通本科生通过名校公开课程和维基百科便可理解得很透彻。

至于说比拼那些社会学知识（哲学、宏观经济学、宗教、语言学、政治学等各种主义），更不用需要依靠什么纯逻辑推理知识了，靠记忆堆叠掉书袋即可。

昨天四海老师猜测，大陆可能会重开比特币挖矿，推动算力回归。很多朋友说，矿老板又不是傻子，谁还敢回去。我感觉大家多虑了。

资本的重要特征，除了不怎么睡觉之外，就是乐于火中取栗。别说中国了，就是朝鲜，只要放开，立刻有大把的钱往里冲，个个都是聪明人，都觉得铁拳砸不到自己。

太平盛世，提前离场，不赚最后一个铜板的，只有李嘉诚。要不说他是李超人呢？

资本逐利，加上本民族的千年老斯德哥尔摩，但凡上头雷霆变雨露，立刻感激涕零、赴汤蹈火。这属于膝跳反应，搂不住的。

咱们当今这位u no who，虽然只有小学文化，虽然脖子压歪了都不知道换肩， 但是作为一个经历斗争、成功上位的独裁者，基本的驭民之术还是有的。这些年颠过来倒过去地折腾，除了确实是文化水平不高、不懂经济之外，最主要的原因就是有恃无恐，精准拿捏了人矿的尿性。

前两天邓屠夫祭日，很多人出来歌功颂德，说再不济也是功过几几开。这就是典型的久治不愈的陈年人矿，是我党最坚实的基本盘。

所以不用担心，只要矿老板们还有余粮，一旦放开，肯定冲。其他行业也一样。

NostrGraph is currently connected to around 200 relays and processing 6,300 events/minute (105/sec). Around 12.4MM (non-spam+valid) Nostr events total.

There’s about 3,000 events/minute that are valid (not spam or invalid). And around 250 unique (valid+deduplicated) events/minute.

An average of around 80 reactions, 75 notes, 50 contact list/relay updates, 30 metadata (no spam filtering) and 10 reposted events per minute.

And thanks to async rust, I’m about 50% 4x (shared) CPU usage with 8GB ram. Plus the server is doing other work too.

意识，是信息处理系统输出的内容。对于人脑来说，如果意识最终不驱动动作或话语或其他信息向外输出的话，那么就相当于没有屏幕的电脑。

生成意识要有感官，将外部信号通过神经系统传递到大脑，由大脑神经元丛进行运算。电脑的键鼠是将外部信号输入进来的主要途径，网络是键鼠的另一个表征。

所以一个意识系统，核心就相当于没有键鼠和屏幕的电脑。

当然很多人认为没有键鼠和屏幕的电脑， 就不是电脑。

How Emotions Are Made，提到这本书，主要是说，感官并没有存储处理信息的能力，都是神经系统传递到大脑的，如果你再读读神经科学方面的论文，会发现，所谓的肌肉记忆，主要是海马体在干活。

哪个论文说肌肉记忆是感官干的？How Emotions Are Made，去读一读？

哪个论文说肌肉记忆是感官干的？How Emotions Are Made，去读一读？

哪个论文说肌肉记忆是感官干的？How Emotions Are Made，去读一读？

没有键鼠和显示器的电脑，依然是电脑。

“做时间的朋友，不如做领导的朋友”真正在中国资本市场如鱼得水的人告诉我的

从国外各个发展阶段的数据来看，确实能得到这个结论。

但是中国有没有可能是个例外呢？比如权力极度集中、户籍制度、极高的贫富差距…

现在对意识到底依附在什么之上没有什么统一的共识，不少学者认为 我们的感官系统也是组成我们意识的一部分。 这样的话，需要脊髓和其他感官器官都做出来，最简单的方式就是要做一个复制人了。

这涉及到一个“意识完整性”的问题，例如 高位截瘫前后的人 是否还是同一个意识。 生理结构上 确实已经天翻地覆了。或者问 人是否有不变的 “核心”。

对我而言没那么复杂， 所有的事物都一直在变化。 我们也无法接触到其他人的“核心”，只能从表面的蛛丝马迹去推敲。 重要的是 “即使那个人再怎么不一样了，现在这一刻，到底我还愿意付出多少精力，去接触，理解那个人。”

如果1:1仿造一个大脑仍然没法产生自我意识，就好玩了😆
