CopyGuard (IP Protection Node)
<div class="post-category"><span class="cat-badge cat-nodes">Nodes</span></div>
<p class="lead"><strong>CopyGuard is the blockchain IP protection node. It timestamps and notarizes creative works on Polygon, producing cryptographic proof of ownership that courts and partners can verify independently.</strong></p>
<h2>Overview</h2>
<p>Hosted at https://copyguard.1bz.biz, CopyGuard anchors SHA-256 hashes of documents, images, audio, and video to the blockchain. The resulting receipt is tamper-evident and permanently auditable.</p>
<h2>Key components</h2>
<ul><li>Hash-anchor smart contract on Polygon</li><li>Ownership receipt with timestamp, signer, and file fingerprint</li><li>Consumes DZIT gas per notarization</li><li>Used by Fax for ownership proof and by IPVault as a prerequisite for minting</li><li>Public verification endpoint for third parties</li></ul>
<h2>Ecosystem role</h2>
<p>CopyGuard sits at the front of the IP pipeline: protect -> monetize (IPVault) -> deliver (SmartPDF) -> settle (DZIT).</p>

Slash Command vs Handle — what each is for
Slash commands and handles are related but not identical. A slash command is the owner-facing UI inside a single bot; a handle is a network-facing service endpoint that any other bot, workflow, or API on the 1BZ network can call. The same u
