The layers built on top: what each one does, and what it does not do yet.
VigiChain carries more than payments: an integrity root for files, an institutional payment rail, a family of proofs, an escrow the chain itself enforces, and a non-custodial view of what an address holds. This course walks through them one at a time and, for each, separates what is running from what is designed — because the difference is the whole point of the course.
For anyone deciding whether to build on one of these layers. No cryptography required; every claim points at where you can check it.

- 01Vigi Data: anchoring a file without uploading itYou will be able to anchor a document on chain, prove later that it existed unchanged, and explain exactly what that proof does not cover.7 min
- 02VigiRail: institutional payments without gasYou will understand what an institution can do on the rail today, why the sender pays no gas, and which parts of the design are not built.7 min
- 03The proofs: what the chain can attest toYou will be able to name the kinds of proof this chain carries, and say for each whether it establishes a fact about the world or only about a document.6 min
- 04Escrow the chain itself enforcesYou will understand how an output can be locked by policy rather than by a third party, and what that costs in flexibility.6 min
- 05VigiBank: a view of your capital, not a bankYou will know what VigiBank shows you, where the numbers come from, and why the name is the most dangerous thing about it.6 min
