Bearer Proof

In the XYO ecosystem, not all data comes from traditional blockchain transactions. One powerful feature that makes XYO fast, private, and scalable is something called a Bearer Proof.

Bearer Proofs are a lightweight, privacy-focused cryptographic feature in the XYO Layer One blockchain. They enable fast, secure verification of data without exposing the full dataset, making the network more efficient, scalable, and private.

What Are Bearer Proofs?

A Bearer Proof is a small, secure piece of information that proves something exists in the blockchain, without needing to show the entire blockchain. Think of it like a concert ticket:

You don’t need to bring your whole purchase history to get into the show. You just show your ticket.

In XYO, that “ticket” is your Bearer Proof. It says, “Yes, this data is valid and part of the system,” without revealing all the data behind it.

Why Does This Matter?

Blockchains are made of long chains of blocks. Normally, to confirm something like a transaction or a data entry, you’d have to scan the whole chain. That takes time and energy.

With Bearer Proofs, you only need:

• The block or data you’re proving

• A small set of linked blocks that show how it fits into the chain

This process is lightweight, secure, and fast—and it protects your privacy by sharing only the minimum data needed.

How It Works: Steps and Step Hashes

In XYO Layer One, Bearer Proofs are not queries or ad hoc hash checks—they are a structural element deeply embedded into the blockchain’s design. The core mechanism behind Bearer Proofs lies in how the chain organizes its data using Steps and Step Hashes.

Each block in XYO Layer One exists inside Steps, "containers" that group blocks together. These Steps are mathematically defined using a primorial-based function. Specifically, each Step size is calculated as the product of the first n + 2 prime numbers, plus one. This produces a predictable but non-overlapping set of increasingly spaced intervals, like:

• StepSize1 = 2 × 3 + 1 = 7

• StepSize2 = 2 × 3 × 5 + 1 = 31

• StepSize3 = 2 × 3 × 5 × 7 + 1 = 211

• …and so on.

Because of this hierarchical nesting of Steps, with smaller Steps embedded in larger ones, the system forms a structure that progressivley includes more of the blockchain’s history, creating a multi-resolution view of the chain.

Think of Steps like versions of a photo stored at different resolutions on your phone. You might keep a thumbnail for quick browsing, a medium version for social media, and the full-resolution image for printing. Each larger version includes more detail, but they all represent the same photo.

In XYO, smaller Steps give you quick proof of recent data, while larger Steps contain more of the blockchain’s history. You only need the level of detail that fits your purpose — just like you wouldn’t load a full 4K photo to view a tiny thumbnail.

This nested Step structure enables efficient Bearer Proofs. When someone needs to prove that a particular block is part of the chain, such as to confirm a balance or transaction, they do not need to walk backward through every block. Instead, they provide the target block along with a compact path of Step Hash-linked blocks that show how that block fits into the broader chain. This path typically includes no more than 100 blocks and is sufficient for validation.

Because this system is embedded into the structure of the chain, the resulting Bearer Proof is lightweight, fast, and cryptographically verifiable. It enables one node to prove inclusion without requiring the other party to scan the entire blockchain. Importantly, it does so without exposing unrelated data, preserving both efficiency and privacy.

Steps also power other important mechanisms in XYO Layer One. For example, Step Rewards, the system’s core reward pool, are issued based on activity within specific Step intervals. This makes Steps not only a structural navigation tool but also an economic unit for incentive distribution.

In short, Bearer Proofs are made possible by XYO’s Step-based design. They are structural, not procedural. They are an outcome of how the chain is built, not a workaround for how it is used.
