Digital Identity Attestation · Earn Points, Exchange Point, Get Real USDT
You can fake a follower.
You can't fake a decade.
MBGExchange reads the history you already have, from accounts you already own, and turns it into proof that a real person has been here for years. We never ask for a password or keep a copy of your data.
Free · Takes about a minute · No wallet needed
Connect your socials
Pick whichever you have had the longest.
Age is what matters here, not how active you are. Each source is approved separately via Vana — your data stays in your own store.
YouTube
The day your channel was created and what you watch.
GitHub
When you joined and what you have built.
Spotify
A listening life — your playlists and saved tracks.
Your career path, education, and who knows you.
The posts and moments that make up your life.
Each source is approved separately via Vana. Approving opens Vana Desktop — approve there, and keep both tabs open until it says connected. We never see a password, and you can revoke access from your Vana account whenever you want.
🛡️ Anti-Sybil protection is active. One source account and one Vana account can each be linked to only a single profile.
The one thing that cannot be bought
Followers can be bought. Posts can be uploaded. Time cannot.
Somebody running a thousand fake accounts can buy every signal the internet normally uses to decide whether you are real. Followers, activity, a filled-in profile. All of it is for sale.
What they cannot buy is a decade. So MBGExchange scores the things that only exist because time passed, and treats everything else as secondary until there is real history underneath it.
Your ChainScore is account age first — every year your oldest account has existed is worth points — plus a smaller bonus for each source that confirms it.
YouTube and GitHub are the only sources that prove account age — the main signal (+3 pts per year, up to +60). Spotify, LinkedIn, and Instagram add the +8 source bonus, and LinkedIn adds a +10 bonus on top. Spotify adds a limited-time +20 bonus if connected before the Vana Cup countdown ends.
Real stakes
Prove you are real. Get paid for it.
