Introducing the 4K Physical Guardian Protocol
The ability to connect the physical and on-chain worlds has long been one of the holy grails of blockchain. Though to date, attempts to bridge these worlds have been centralized, ad-hoc, and rife with misaligned incentives. At 4K, we’re building a decentralized protocol for connecting the on-chain and physical worlds. While a centralized approach would be easier, we believe that only a decentralized approach is capable of making physical assets a new, trusted web3 primitive. A decentralized a...

The 4 Different Types of NFTs for Bringing Real World Assets On-Chain
Bringing real world, physical objects on-chain has long been a “holy grail” for the world of crypto. NFTs and the underlying blockchain technology offer new forms of value creation, making a Web3 transition the next logical step for industries dealing in physical goods. There are a number of Web3 projects aiming to tether the physical world to the digital one. We’ve identified the strengths and weaknesses across different classes of “phygital” solutions to demonstrate where they succeed and w...

At 4K we are building the Physical-Digital™ bridge, a decentralized protocol that enables anyone to bring physical assets on-chain as physically-backed NFTs.
To understand this innovation, we must understand the importance of bringing physical-assets on chain in the first place.

The physical world is fundamentally uncertain, especially with trust-based transacting. Say you're buying a Rolex on the secondary market from a reseller — how are you sure the watch is authentic? How can you accurately trace provenance without bypassing the reseller who acts as a gatekeeper?
This is one of the problems solved by an NFT. By bringing a physical asset on-chain, you're creating a transparent ledger of your asset's history. You're able to track every previous owner, maintenance and repair reports, condition grades, and any supplemental evidence of authenticity. This can apply to all NFTs backed by physical-assets, including sneakers, handbags, tradings cards, and high-end collectibles.
A physically backed NFT allows you to sell your asset without it ever having to be re-authenticated or re-graded. The NFT grants full transparency for the authenticity of your physical asset.

A major issue with current Web 2.0 marketplaces are the excessive fees on seller transactions.

A major issue with current Web 2.0 marketplaces are the excessive fees on seller transactions.
With an NFT, you're able to accept crypto as a payment and sell your asset for a premium. NFTs allow you to seamlessly trade on a variety of Web 3.0 platforms that have significantly lower fees than traditional Web 2.0 platforms (eBay, Stock X). For instance, if you wanted to sell your NFT on our 4K marketplace (4K.com), you would only pay a 1% transaction fee.
Also, with traditional Web 2.0 marketplaces, you're at the mercy of out-dated protocols. Transactions and settlement times are slower, difficult to scale up due to logistics, and you have limited access to international markets or goods.
With an NFT, transaction and settlement times are fast, efficient, and scalable, opening the world to easier global commerce.

An NFT backed by your physical asset opens the door to various financial opportunities through Decentralized Finance (DeFi).
Anyone can use physically-backed NFTs as collateral in a loan, a means of fractionalization, or even as the basis of a stablecoin.

People will no longer need to be in physical proximity of a physical asset in order to use it. Idle physical assets will be brought into the Metaverse, become the basis for membership into social clubs, and enable other use cases we can't yet imagine.

As you can see, there are many benefits to physically-backed NFTs. 4K is dedicated to acting as the premier coordination layer between the physical and digital worlds, unlocking the newfound, limitless possibilities of physical assets on the blockchain.
