Sports brand Nike patented a system dubbed CryptoKicks that tokenizes shoes on the
The patent, published on the 10th of December describes a digital asset for footwear and its
use cases. One feature of the technology described is an Ethereum ERC72/ERC1155 token
used to verify and transact the physical shoe.
Shoewear on the blockchain
Unlocking the token would be done by purchasing the corresponding physical shoe. In
practice, this is performed by linking a 10-digit identification code with the owner
identification code. The purpose of the system is to ensure the authenticity of goods. This is
described as following in the patent:
''Prospective and current owners [...] may buy and sell digital assets through one or more
ledgers operating on the decentralized computing system. [...] By way of
example, and not limitation, a user may buy a new pair of highly sought after sneakers from
a verified vendor who may provide authenticated provenance records for the sneakers. [...]
After receiving the shoebox containing the purchased sneakers, the user scans the box UPC
with a barcode scan feature in a sneakers app operating on the users smartphone.
Fascinating is that Nike also implicates that token creation may be linked to physical shoe
sales. This would allow for the verification of the scarcity of the shoes in circulation. The
When a consumer buys a genuine pair of shoes a digital representation of a show may be
generated, linked with the consumer, and assigned a cryptographic token, where the digital
shoe and cryptographic token collectively represent a CryptoKick.
If the footwear is sold, ownership of the digital token is passed on alongside with the
physical product. The storage of those tokens would be managed in an exclusive Nike app,
increasing brand engagement.
Nike to allow breeding shoes on blockchain
Reading the patent, it becomes apparent that Nike has done its homework. Certain concepts
have been taken from the successful blockchain game CryptoKitties. More specific, an idea is
described in which footwear owners can breed new shoes. The patent reads:
Using the digital asset, the buyer is enabled to securely trade or sell the tangible pair of
shoes, trade or sell the digital shoe, store the digital footwear in a cryptocurrency
other digital blockchain locker, intermingle or breed; the digital shoe with another digital
shoe to create shoe offspring, and, based on rules of acceptable shoe manufacturability,
have the newly bred shoe offspring custom made as a new, tangible pair of shoes.
