I learn about all kinds of cryptography, and try to use it to make the world a little better. You can see a few explorations at voboda.com

"[Palantir workers] joined a company that promised to stop abuses of power, and they are watching it build the tools that make those abuses faster, wider, and harder to undo. The question they are left with is ... at what point does building the machine make you responsible for what it does?"

Had quite a few "oh shit" moments reading this. And it's mostly stuff I thought I knew. sockpuppet.org/blog/2026/03...
jbp.io/2025/05/02/g... "I view GHA runners as public, unsecured shell boxes that I can run scripts on. They can check out and build public code, but at no point should they be given any kind of privileges or secrets."

You use a bare Git repo with a `post-receive` shell script hook. I use GitHub Actions: remote YAML, swiss-cheese key management, OIDC trust glue, job orchestration, delimiter-delimited metadata, opaque internal headers, microservice spaghetti, bug bounties, and CVEs to match. We are not the same.
… are fucking kidding me. A github.com cross-account RCE due to the most pedestrian of injection attacks along the obvious exposed surface… and they actually have a globally shared “git” UNIX user!! This is not what taking the role of supply chain stewards seriously looks like.

It's pencils down at the hackathon. I put 236 years of US copyright law into a git repository. Every Act of Congress from 1790 to today is a commit. Still some work to be done, and things got frantic at the end, but I'm proud of this! github.com/katelynsills...

"Crypto was a community that had been building for almost a decade. Economic design was what they did. And nobody had addressed the economic design problem that made their conference weeks full of over-hyped but mostly empty events?" Here is my attempt. blog.voboda.com/density-index/
Working on zkal, I realised I was tackling a general problem: returning to the benefits of open data for communities, but with modern privacy protection for the individual. Came up with a pattern that might be useful (or flawed!) blog.voboda.com/proof-projec...
"using network architecture to solve issues of power distribution simply shifts bottlenecks rather than eliminating them. A decentralised protocol does not automatically produce decentralised governance, it also moves power to different, less visible places." connectedplaces.online/reports/fedi...

The Moltbot rename and supply-chain attacks that followed: www.malwarebytes.com/blog/threat-... I run all my dev in a hardened container, but this type of attack grabs API keys silently, and uses them to watch communication. Any ideas on mitigation?

I'm glad this is coming to the forefront. I was deeply inspired by Nikolai Mushgian's attitude to this ( see nikolai.fyi and look at dmap, dpack and minicash's doc ) I even made a little game about this philosophy for Devcon SEA: immutalists.infinite.build
Just called pledge on trustlessness.eth.limo A bit late as it came out in a very busy time of my life due to @devcon.org - but now finally found some time finally process the manifesto and sign. Signed it as ligi.ethereum.eth Thanks to Marissa Posner, Yoav Weiss, @vitalik.ca for the initiative!
