Blockchain and NFTs have been controversial for a while now and it appears Valve wants none of it since games associated with them are getting removed from Steam.
Blockchain and NFTs are often mixed up with shady dealings as bad actors tend to scam people out of various amounts of money, going as far as millions of dollars. As such, one would have to be extremely wary of dealing in such things and it appears Valve doesn't want to get involved at all.
A series of tweets from Age of Rust creator, SpacePirate, revealed that Valve no longer allows "Applications built on blockchain technology that issue or allow exchange of cryptocurrencies or NFTs". In case some of the words in that sentence sound unfamiliar, like they do for a lot of people, here is a quick glossary:
- Blockchain is basically a digital ledger that requires massive amounts of computing power to alter so it's close to impossible to mess with
- NFTs are digital receipts, kept in the aforementioned digital ledgers
- Cryptocurrencies are used for NFT-related transactions
Valve has been fairly quiet about the situation and didn't reveal too much about the reasons for the ban on blockchain, NFTs and crypto but SpacePirate's tweet chain alleges that Steam has issues with items that have real-world value. This is a bit odd considering Steam marketplace is a thing, hinting the issue may be something else entirely.
Considering the blockchain trading are is home to vast amounts of scams currently, we would hazard a guess this is related to the ban from Steam.
