Bound Witness: Real-World Examples

Selfie at a Concert

Imagine two friends meet at a concert. To prove they were both there, they take a selfie together and each saves a copy on their phone. Later, if someone asks whether they really went, they can each show the same signed photo. Neither has to trust the other’s word alone — they both have a shared, verifiable record.

Bound Witnesses in the XYO system work similarly—when two devices agree on an event and cryptographically sign it, their shared record becomes a trusted piece of data.

The Handshake Business Analogy

Think of a Bound Witness like an old-fashioned business handshake — but with receipts. Two people meet, agree on something, and both write it down and sign it. If one later denies the meeting, the other still has proof — and ideally, both records match.

In XYO, when two nodes interact, they exchange information and both digitally sign the event. Each keeps a record in its own ledger. That mutual signing creates a trustless proof — like a handshake sealed with cryptography — that can’t be faked or denied later.
