Problem
In traditional systems, trust requires giving up control to a central authority. Blue flips this model—each participant maintains their own signed record while sharing only what others need to know.
Here's how it works in practice: When Alice buys a course with a 7-day refund guarantee, she posts her `RequestRefund` to her timeline. Stripe sees this request, checks the contract terms (Is it within 7 days? Is this a valid request?), and posts its own `RefundProcessed` event. Bob, the course creator, sees the refund on his dashboard with proof of exactly why it happened. No arguments about whether the request was on time—the verified timeline evidence is clear.
This approach means every change has a verifiable source. It's like having a receipt that proves not just what happened, but who did what and when—all without requiring everyone to maintain a copy of every transaction in existence.
Timeline options range from convenient MyOS managed timelines to institutional timelines with strong identity verification to blockchain-based options for maximum decentralization.
The result? No screenshots as evidence. No disputes about what was said or done. Just verifiable events that create transparency for all participants.
