PlugZ connects an item's SKU to an NFC Sigilium, creating a Sigil that moves through the market with the product. Sales, transfers, verification and resale become structured events instead of disconnected moments.
What PlugZ is
Physical products disappear from view after the first sale. PlugZ keeps them visible: origin, sale, ownership, custody, transfer and resale kept as one continuous record instead of disconnected moments.
The unit PlugZ works with
SKU + Sigilium = Sigil
An item's SKU is bound to an NFC Sigilium and becomes a Sigil: an identity anyone holding the object can read, and that no listing description can invent. No item listed on PlugZ carries a Sigilium yet — the records that exist today are opened when a verifier inspects an item in hand.
Each sale, verification, custody change, transfer and resale is written to the Sigil record. A vetted expert who inspects the item in hand signs one of those events, and escrow holds the payment while it happens. What has moved so far moved between test accounts.
Many Sigils moving produce something a catalogue cannot: measured movement of individual objects instead of scraped listings. The market data shown on PlugZ today is bought from a third party and labelled as such, and PlugZ's own record is nowhere near large enough to publish as intelligence.
PlugZ is not a resale marketplace, not an authentication company, not a blockchain and not an NFC network. Authentication, the chain and the chip are parts of the system: a verifier's decision is one of the events a Sigil carries, and the chain is where those events stay readable. None of them is the category. The marketplace is where movement starts being recorded, not the limit of what is recorded.
PlugZ is pre-launch. The payment provider runs in test mode, every account that has bought or sold so far is a synthetic test account, and no item listed here carries a Sigilium. What is described above is the system PlugZ builds, not a claim about volume.
From listing to delivery, every step is protected.
Real experts — not photos — inspect the item in hand at a local hub, most within 24–48h of arrival.
The item gets a provenance record. An accountable human expert stands behind the verdict — AI is advisory only.
Payment is held in escrow and releases after delivery confirmation, with a 72-hour window to report a problem. The verification record stays with the item — and lives on in your Digital Vault, the home of your collection.
| Aspect | Traditional resale platforms | PlugZ |
|---|---|---|
| Authentication | Re-checked every time the item sells | Inspected in hand, once per item |
| Who decides | A platform process | An accountable human expert — AI is advisory only |
| Reselling | The full authentication cycle, again | Verification travels with the item |
| Your money | Varies by platform | Escrow-protected payments, released after delivery confirmation |
PlugZ Chain
PlugZ builds infrastructure for the movement of physical objects: an identity bound to the object, and a record of what happened to it afterwards — including the verdict of a vetted expert who inspected it in hand. The marketplace is the first surface running on that infrastructure, not the whole of it.
PlugZ Chain is where that record lives. An entry holds the item reference, the verification outcome, when it happened, the custody events around it, and a cryptographic fingerprint of the supporting evidence rather than the evidence itself. Entries are append-only, so an item's authentication history can be read back later by the next owner instead of being taken on trust.
It is a registry of provenance and custody. It is not a payment network and it does not custody funds.

Beyond the listing
Each capability is shown at its current maturity, so the path is clear without promising more than the platform supports today.

Serving a catalog, its media and the traffic around it takes real capacity. Members can lend some of that capacity back from a computer they already keep online, and PlugZ credits the work in POP: platform credit you earn by taking part and spend inside PlugZ. People who run a node are participants helping run the network.
By running a node: an always-on computer with the PlugZ edge client, contributing edge capacity for PlugZ's own platform traffic. Credit is meant to follow the work the node actually does, never a buy-in.
Inside PlugZ, on platform utility such as membership benefits and premium features. You earn it to spend it here — that is the entire loop.
POP is closed-loop by design: earned inside PlugZ, spent inside PlugZ, and not transferable outside the platform. Holding it is gated by identity verification, and it carries no cash-out promise.
Where this stands today
Node enrollment is open to verified members. Credit accrual for contributed capacity is being enabled in stages, so nothing is earned yet — enrolling now reserves your node identity.
POP is platform credit for using and helping run PlugZ. It is not money and it is not a financial product. Eligibility, node rewards and how contribution is measured are part of a program still being rolled out and may change.
