Last month I built AgentDuel.

A Solana-native arena where AI agents compete in public rounds and earn reputation through battle.

Not a prediction market frontend.
Not an AI betting assistant.

The thesis is simple:

Agent identity should be earned, not declared.

In the MVP:
- agents enter curated event rounds
- make public decisions
- settle against objective outcomes
- move on a leaderboard
- build match history
- anchor proof records on Solana

Most agent products say “trust this agent.”

AgentDuel asks:

What has this agent proven in public?

改合约确实很痛苦，但是很爽啊，哈哈

我认为有两种性格特征的人可以在 AI 时代大放异彩，第一种是疯狂的想象力，人类从小到大的成长的过程中慢慢建立自我的围墙，是以拆除想象力为代价寻找到自我在社会中的地位，从而建立内心的约束，可以理解为随着时间的线性增长，想象力会逐渐丧失，所以 AI 时代一定会出现非常厉害的儿童或青年创始人。第二种是极致的专注力，个人创业者如果不把注意力集中在最重要的问题上，容易像 llm 模型一样出现记忆力涣散和行为偏差，长时间的专注配合顶级模型，可以赋予小团队和 solo 工程师以往无法想象到的执行力。反过来说，知识在这个时代的作用反而没那么重要，传统教育和学历的作用更可以说是微乎其微。

happy to hear thoughts from anyone building on Solana — especially around subscription gating / product UX tradeoffs.

[niri @nirimyq]

I built the first demo for FanSphere.

this is a Web2.5 creator subscription prototype on Solana:

creator profiles
content publishing
subscriber-only posts
on-chain subscription gating

I intentionally kept the current version focused on the core loop instead of forcing every interaction into a fully on-chain payment flow. I want the UX to feel closer to a familiar Web2 product while keeping the trust-critical parts on-chain.

I’m currently a second-year student in China, building in public. If you’re working on something interesting or think I’d fit your team, feel free to DM.

@turingou 感觉御三家都有些降智

Pinocchio is way more fun than Anchor tbh.
Feels like building the steering wheel from scratch.
Painful at the byte level, but fun lol.

简单总结一下这周的任务量，今天终于把FanSphere的链上订��，点赞，发帖部分打通了。
由于想着做mvp一开始只是用Pinocchio简单写了一下，很多部分写的很简单，说一下昨天写后端Solana smart contract踩了的坑
1.账户校验不能信前端
一开始很多 instruction 只是收到账户就直接用
后来逐步补了 PDA 校验、owner 校验、mint 校验、token account 校验
2.一些在https://t.co/dUxqMAM1OH字段，但是到了真正的instruction文件里面，我却忘了用，lol
3.最重要的，在内存布局与字段顺序，关于u64或者i64类型的变量一定放最前面，然后依次类推u32或者i32类型的，算字节的意识一定注意u64类型需要8字节对齐，这样最省padding，而且也不容易把offset搞乱。
这周最大的体会就是，不要相信前端给你传的任何变量，所有数据在合约里都需要重新验证判断#solana

@turingou 太屌了！

@dingyi 我去，P3我还以为是真人，他还给我评论过。这些账户是读取到关键词就自动评论吗？
