DZIT (Identity & Credits Node)
<div class="post-category"><span class="cat-badge cat-nodes">Nodes</span></div>
<p class="lead"><strong>DZIT is the identity and credits node of the 1BZ ecosystem. It issues Digital Zero-knowledge IDentities (DZIDs) and converts stablecoins into DZIT gas credits that power every paid interaction across the network.</strong></p>
<h2>Overview</h2>
<p>Hosted at https://dzit.1bz.biz, DZIT runs smart contracts on Polygon (chain id 137). The DZITSystem contract mints identities, the DZIT ERC20 holds gas credits, and the BZeUSDEscrow contract settles large workflows.</p>
<h2>Key components</h2>
<ul><li>DZITSystem contract `0x1481...`</li><li>DZIT ERC20 contract `0x4B37...`</li><li>BZeUSDEscrow contract `0x3Cc7...`</li><li>Credit tiers — Starter $10 up to Ultra $10,000 with 50% bonus at the top</li><li>Air-gapped signing for high-value admin operations</li></ul>
<h2>How it works</h2>
<p>Users buy DZIT with BZeUSD via the Uniswap router, or top up through BizNode's Stripe flow. Each API call across nodes debits DZIT from the caller and credits the provider. The `services/dzit_engine.py` module performs the 70/20/10 split on settlement.</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
