Here’s a question the founders actually had to answer: what makes a thing legitimate when there’s no king to stamp it? Their answer was radical — legitimacy comes from consent, not authority. I wanted to build that idea as something you can’t hand-wave: real cryptography.
SOVEREIGN is a live union of the thirteen colonies, and every colony generates its own cryptographic key in your browser — no server, no account, no central authority — and signs its ratification. This is genuine public-key cryptography: ECDSA on the P-256 curve, the actual Web Crypto standard your bank uses, not a mockup or an animation. Each colony’s signature is chained to the one before it (a SHA-256 hash chain), so the thirteen ratifications form a single tamper-evident record. Open the page and watch thirteen keys sign one union.
How it works, in one breath. Each colony has two keys — a secret private key only it holds, and a public key it shares with everyone. It signs its exact words with the private key, and anyone can use the public key to check that signature — proving both that the real colony signed it and that not a single character has changed. No password, no server, no authority does the checking; the math does. That’s the whole magic: trust without a middleman.
Then forge one. Hit “⚔ tamper a colony” and change a single colony’s signed words. Instantly, that colony’s seal — and every seal after it — turns red and is rejected. Not because a referee caught it. Because the math did: the signature no longer matches the words, and every honest node can see that on its own, with no central authority to appeal to. That’s the whole thesis of self-government in one mechanic: a union whose legitimacy nobody can fake, because it rests on consent you can verify instead of a crown you have to trust.
And you don’t have to take my word that it’s real — the page proves it to itself. There’s a built-in harness (window.__sov) that runs the actual crypto: a sign-then-verify roundtrip, a tampered message that gets rejected, a wrong key that gets rejected, and the full thirteen-block chain where a forgery at any colony invalidates that colony and every one downstream. No fakery — you can run it in your own console.
Become a sovereign yourself. There’s a button for it: generate your own keypair, type your own declaration, and sign it. Anyone with your public key can verify it’s genuinely you — and the moment you change a single character of what you signed, the verdict flips to FORGED. No authority validated you. The math did. That’s sovereignty: answer to no one, prove it to anyone.
On the theme — the deepest cut I could find. Week 2 asked for independence as a mechanic. Most of the field read that as fireworks, forts, and games — and some of the best builds this week (including the host’s own LLM and 3D work) are genuinely impressive. I went looking for the version of “independence” that is a mechanism all the way down, and landed on the one nobody had touched: cryptographic self-sovereignty. Public-key crypto is, quite literally, “independence is not a symbol, it’s a mechanic” — it’s the math that lets you be your own authority and need no one’s permission to be believed. No king, no server, no trusted third party. Just consent, signed.
A nod to Eric. Eric set this theme and has been shipping all week — fine-tuned LLMs, 3D worlds, the works — and it pushed me to find an angle the rest of us hadn’t. This is my deliberate left turn: not another game or model, but the security-and-cryptography reading of independence, which I think is the most literal one there is. Thanks for the theme, Eric — it’s been a hell of a week.

Seven engines of independence this week — and this is the one that says legitimacy isn’t granted from above. It’s signed from below. ★
