The 4K Protocol acts as the foundational infrastructure for allowing anyone to convert physical assets into physically-backed NFTs. The protocol consists of Physical Validators, Oracles, and Guardians which are incentivized via a token system to create a decentralized web of storage provision and authentication. The 4K Protocol will be leveraged by a myriad of future applications that require the infrastructure of the Physical-Digital Bridge.

The 4K Marketplace acts as a discovery and aggregation layer on top of the 4K Protocol. The 4K Marketplace is the defacto home for discovery and trade of physically-backed NFTs enabled by the 4K Protocol.
