When you work on vulnerabilities/exploits, the best ones are chains.
Q: Why am I looking to exploit EtherDelta orders for orders from an exchange that died in 2017?
A: Because I can extract the signed orders and get remaining fill... to buy Wyvern DAO token (died 2021)... to get a majority stake on this dead exchange... to cause a protocol upgrade... to execute the admin backdoor in prior OpenSea contracts... because tokens still approve them... so I could show those tokens can be taken... because... ... ... because it's Wednesday.
So the lesson learned is that if I passed out with my kids reading Harry Potter stories on Wednesdays, I wouldn't find these things.

@MHeadd RE civic.io/2026/03/16/end…
There's many studies in the open source world about the impact of AI on our repositories.
They usually measure impact in terms of lines of code.
But this is missing the major point because the main measure is time. And every self-respecting open source participant has a long backlog of projects that won't change their career or their fortune and just remain side projects.
These projects will forever remain in the backlog. No amount of AI is going to change that.

Anthropic, in its mission to build systems that people can rely and not committing mass surveillance or fully autonomous lethality, has identified that the US Department of Defense is a supply chain risk. Therefore they have stopped using DoD technology including:
- the Internet, TCP/IP
- Intel/AMD chip fabrication, x86 architecture
- NIST-influenced cryptography

@GeoCities_eth You are claiming this is you. Other than the trademark that you are claiming you purchased, do you have anything else going here?
English

Does anyone want to be part of brining back GeoCities to the internet?
It’s not just an idea, we own GeoCities®️ and the brand.

Operating in stealth mode is almost always a mistake. Talk publicly about what you're building. You’ll build momentum, get real feedback, and someone will reach out with the other half of your idea you didn’t realize you were missing.

Are you using Polymarket or other prediction markets? How has your experience been? Do you have any advice for me?
William Entriken@fulldecent
I have been writing an automated trading bot against @Polymarket and want to share some of what I learned and open source most of the code. Do you think you're smart and want to build generational wealth by vibecoding and taking money off of fish? Then here you go, have fun!

In closing, here's the code. I'm dropping the first part today.
Ask me anything about betting markets data.
Have a great day!

As for why am I publishing this, I'm interested to connect with other people that are doing this kind of data science. And we are all here to learn, that's the point of life.
I remember meeting a girl once, I forgot her name, but her license plate number was "ERC-721". And we were talking about this exact same question. She is a professional quant trader and she told me: why publish alpha?
Well, here's my answer: everything that everybody says is alpha. That's why humans have ears, so we can get the alpha into our heads!

@ethereumfndn The community should affirm the promise of Ethereum.
And the existence of EF's AllCoreDevs and the anonymous ownership of Ethereum.org is actually censorship in itself of community control. lol

@ZainanZhou Notes added to EM. But the file itself also a broken link. Also noted in EM.

@fulldecent Oh, maybe i didnt ellaborate it well enough, could you suggest edits?
English

@ZainanZhou That is all correct.
And there is a specific reason that zeros are cheaper. And the market shows us that this specific reason is more important than choosing any other prefix digits. So this specific reason should be cited in the document, since it is not obvious.
English

Thank you, William.
Our ERC does not strictly require the use of zero; it can also be other numbers. You can see that these can be represented using the same subscript extension method.
However, I chose zero when developing PrettySafe for the following reasons:
1. Industry Adoption: There is already significant industry adoption from projects I have listed, such as Uniswap and ENS.
2. Technical Efficiency: In many circuits, zero is much simpler to use for comparisons.
3. Cost: Using zero is relatively cheaper than using other numbers.
