Key terms and concepts

Iterati Label

The Iterati physical authenticity label is an encrypted, non-cloneable, NFC based authenticity label which creators attach to their physical artworks as part of the certification process. Labels are tamper-evident and cannot be removed/reattached to another object after initial application.

Certificate of Authenticity

Iterati's Certificates of Authenticity are digital descriptors/profiles linked to every physical label that contain metadata about the label and its associated physical artwork. Certificates of Authenticity are stored using a decentralized data store called the Ceramic Network.

Collection Enrollment

Enrollment is the process of adding a new collection to the Iterati platform, either by importing an existing NFT smart contract or deploying a new custom NFT smart contract through Iterati.


A collection is a logical grouping of artworks. Traditionally, artworks that share a common aesthetic, theme or are meant to be displayed together are grouped into collections. On Iterati, artworks within the same collection are minted to the same smart contract and share a single storefront, which creators are able to customize with collection-level metadata.


Adding an artwork to Iterati can be thought of as creating a digital profile for a physical artwork. This digital profile contains text and image based metadata that gets seen by collectors who tap its associated NFC label.


Certification describes the process of attaching an Iterati NFC label to a physical work and linking that NFC label to a digital profile on Iterati with a Certificate of Authenticity.

Underlying Technologies


NFC or Near-Field-Communication is a short-range wireless communication protocol, typically requiring a distance of 4 cm or less to initiate a connection. NFC lets you share small payloads of data between an NFC tag and powered devices like modern smart phones.


AES-CMAC, based on the Advanced Encryption Standard (AES), is a highly secure method for verifying the authenticity and integrity of information. It generates a unique code (or tag) for data, making it extremely difficult for unauthorized parties to alter or forge the data without detection. Iterati labels use AES-CMAC to ensure every NFC tap is authentic.


The Interplanetary File System (IPFS) is a decentralized file system for storing and discovering content over a peer-to-peer network of nodes.

Ceramic Network

The Ceramic Network is a decentralized data network built on top of IPFS enabling applications to upload, mutate, and index data stored on IPFS nodes.

Non-Fungible Token (NFT)

Non-fungible tokens (NFTs) are unique cryptographic assets on a blockchain with unique properties and metadata that distinguish them from each other.
