# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.xyo.network/xyo-layer-one/xyo-layer-one-features/bound-witness/bound-witness-real-world-examples.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
