The ledger
Try to tamper with it
Pick a committed block, change what it says the balance was, and verify the chain. This is the same check a real auditor would run — nothing here is hidden from you.
What this demo is, and isn't
What's real here
The hashing is genuine SHA-256, computed by your browser as you interact — nothing is precomputed or faked. The fund itself is never withdrawn: it keeps its full yield every year. The citizen instead draws on a credit facility secured by the fund, hard-capped at 75% of its value — a draw that would push past that ceiling is refused outright, checked before anything commits, not after. Government's share, by contrast, is a genuine outflow that does leave the fund, but it's capped at that year's yield so the fund itself can never shrink. Tampering with a past entry breaks verification the same way it would in the tested backend.
What's simulated
The 13-validator quorum shown on each block is illustrative here — this page doesn't run real independent signing processes. The actual multi-validator consensus, with genuine Ed25519 signatures from independently-keyed validators, is implemented and tested in Python (78 assertions, including the exact Byzantine-fault boundary). This page is a demonstration of the mechanics, not the production network — see the investor overview for what that distinction means in practice.
