由AI赋能的应用普及的那一天，就是自主权数字身份彻底绽放异彩的时刻。AI的发明是为了服务人、帮助人、解放人，这一切的前提是对人的身份与权限的鉴别。未来AI在替某人进行任何操作之前，必然会问：这10块USDC他能花吗？这辆车他有使用权吗？这份合约他有权利签字吗？对人的标识，对财物的使用和控制权，对各种主体之间权限和支配关系的判断，是AI可以进行有价值工作的前提。
未来人与智能体之间的交互，必然不会再是基于存储在一个个离散的小数据库内的用户名密码的形式。为什么？首先是数据的离散和碎片化不利于大一统的AI操作系统的使用。其次，鉴于AI算法的不断壮大，AI去修改数据是再正常不过的事情。我们有理由认为任何普通数据库内存储的身份信息、操作规则和鉴权方法都会失效。
所以，人与物的数字身份，必然会进化为某种可以让AI直接理解和进行互操作的形态，但是又不能让AI直接控制、操纵和篡改。那么基于密码学的数字身份与数字凭证，就是最自然的选择了。一力降十会。纵使强大如GPT，在密码学绝对的算力墙面前，还是要甘拜下风，束手就擒。而后量子时代的密码学进展会为这种方法再加上一层铜墙铁壁。如此未来，真正可期。

用于自主权数字身份的公钥基础设施有两个有趣的需求，在设计的时候必须都能覆盖到：
第一天，他说他是至尊宝，那他可以证明他真的是至尊宝。
第二天，他说他不是至尊宝，那你仍然可以证明他就是至尊宝。

GPT-4带来了有一个很有意思的问题，那就是它彻底颠覆了过去基于网页点击和流量的互联网行业模式：如果我可以直接从GPT-4那里获得我想要的信息，那我为什么还要去点击谷歌搜索的链接？如果我不点击链接了，那谷歌广告还能存在吗？网站的流量还能存在吗？
那么问题来了，靠广告和流量作为收入的创作者，他们的收入怎么办呢？如果他们因为收入骤减而停止了创作，那么也就没有更多优秀的语料去训练和提高GPT-4了。这种局面，OpenAI应该也不愿意看到。
解局的方法是什么？就是Web3的核心：个人主权数据。让GPT-4的在使用我的数据时，直接给我带来经济收入。比如这段文字，因为有了我的数字签名，也就宣示了我的数据主权。

I think compared to PGP, the W3C got most of the stuff standardized, especially the part with verifiable data registry—the storage of the identifier and associated public keys. But the most important part is actually verifiable credentials and DID is like setting up a stage for it. I guess we don't have that with PGP.

Some pos supporters will argue that with money, you can buy mining machines to generate proof of work. And with money, you can buy coins to generate proof of stake. So really, how is pow and pos different if both can be purchased with cash?

A DID is a unique identifier of an entity. This identifier is generated by cryptographic method, just like a Nostr key, and you hold the private key. So you can say it is self-sovereign because only you ave control over this DID. In reality, this identifier is linked to a series of keys for you to use in different scenarios.

Nostr has delivered user Self-Sovereign Data with one simple json export. Your social relations, your notes, your replies, your reactions... all in one json file. So simple, so reliable, so elegant!

2023-02-26 01:25:02

用户自主权数据，Nostr又一次实现了世界第一。Iris客户端，现在可以一键下载你的所有社交关系，一键下载你的所有社交活动，包括所有发帖、回复、点赞等事件。全部以一个json文件形式存储在你自己本地，并且可以在新的客户端一键恢复。
我自己2个月正常使用的社交活动文件有多大呢？500KB。这个大小是什么概念？我的iPhone能装52万个这么大的文件。
“Web3要让用户拥有自己的数据”，口号喊得再响，也不如一个简简单单存储在本地的json文件让人心安。一切皆文件，Unix精神永存。

AI技术的三大支柱是：算法（模型）、数据与算力。而零知识证明的技术要素与之非常相似：也是算法、数据与算力。目前，ZKP的算法与算力（挖矿）已经得到了充分的重视和讨论，但是ZKP计算所需要的数据却很少被谈及。要知道，如果不能从源头上保证输入数据的真实性，那ZKP就真的成了 garbage in, garbage out.
The three pillars of the AI technology is algorithm(model), data and computation power. Interestingly, they are also the pillars of zero-knowledge proof. As of now, enough attention and discussion have been given to the ZKP algorithm and computation power (ZK-mining), but little given to the data used in ZKP. Know this, if the data authenticity/validity cannot be guaranteed, a ZKP just becomes "garbage in, garbage out".

用zk做证明有一个前提，那就是你要使用真实的数据进行证明。如果源头的数据就是假的，那做出来的zk证明是无效的。

I agree the term has lost its original meaning. It is sadly true that many projects just use it as a fancy concept to shill their token. But I liked the idea of returning the control of user identity to the users—what Nostr is enabling.

2月1号在国内安利了Damus，这几天Nostr话题太热闹了。再简单说两句。
其实，Nostr的核心不是无审查的社交网络，而是用极精简的协议实现了自主权身份标识(公钥)和自主权数据(带Schorr签名的event)两个核心技术。至于relay、client和社交的部分，那都是赠品。
这套极为简单却又极为先进的去中心化数字身份与自主权数据架构，才是下一代互联网真正的雏型。这一点，只有Jack自己投资的Bluesky能与之匹敌。但是Nostr出现得更早，又是来自于比特币社区、继承了比特币精神的原生产物。配合闪电网络支付，未来的玩法可谓千变万化。
继续期待，继续buidl。
