BetterSign™
Your identity stays the same for life while the keys securing it rotate freely — like keeping your phone number when you swap the SIM.
A Verifiable Long-lived ADdress binds a nonce to the CID of a WASM verification function. It commits to a verifier, not a key, so it survives unlimited rotations.
A stable name on the outside, freely changeable keys on the inside.
The picture
A VLAD is like a phone number that stays the same when you get a new phone. You keep the number; the SIM card inside changes. In BetterSign, you keep your name while the keys inside it change.
The VLAD is a nonce + WASM-CID tuple that addresses your provenance log. The keys advertised under /pubkey rotate with every entry, but the identifier the DHT resolves to never changes.
What it fixes
How it works
You create an identity, which gives you a VLAD — your permanent name
BetterSign starts a signed logbook for it
Every key change adds a new signed page to the logbook
Anyone can replay the logbook and check every page is legitimate
They always end up with your current, correct keys — without asking anyone
The building blocks
A VLAD remains stable while its keys and protected metadata rotate.
Every state transition is hash-linked and authorized by the previous log state.
VLADemlia helps peers locate current records without becoming the trust root.
Key changes become signed updates that followers can verify and apply.
The jargon, translated
Questions
No. Point your tools at a VLAD and BetterSign keeps the keys current for you — SSH that doesn't break when keys rotate, TLS that renews itself, API tokens you can rotate freely.
Recovery is built in. A stronger, better-protected backup key can fix things if a normal key is lost or stolen — no out-of-band scramble.
The longer a single key stays in use, the more chances a copy ends up somewhere it shouldn't. Rotating retires old risk — like changing the locks now and then.
No. A VLAD is owned by you and no one else, proven by math anyone can check, and still verifiable years later — even offline.
