In a post Wednesday, Ethereum (ETH) co-founder Vitalik Buterin expressed his desire for soulbound non-fungible tokens, or NFTs, like the eponymous item class in the popular MMORPG World of Warcraft, or WoW. In explaining his reasoning, Buterin explained that there is no way of knowing whether the person attended the auction in order to obtain it, or whether they simply bought it, if someone proves that they own an NFT that is passed through X can be purchased, e.g. B. by participating in an NFT auction on the secondary market.

The “soulbound” feature in WoW prevents an item from being traded, shipped, or sold to other players in the game’s auction house. It was designed by the developers to prevent high-level characters from “winking” to low-level characters in order to drastically speed up the grinding process of fighting monsters to gain experience.
However, they are also used to demonstrate achievements, meaning that the character earned the item by defeating challenging bosses and not a relic. The latter property seems to be of interest to Buterin, as the Ethereum co-founder addressed that on-chain offerings to store driver’s licenses, college degrees, etc. would run into problems if someone who didn’t meet the required conditions could easily acquire them she. .
Buterin also referenced the Proof of Attendance Protocol POAP project, which stores digital memories of a person’s life on-chain and issues a unique badge backed by a cryptographic record. The team behind the project encourages developers who care about portability to “check on the chain that the current owner has the same address as the original owner.” But as with soul items in WoW, removing the portability of NFTs would presumably remove their commercial viability as well.
