What? Rumors work by people discussing them.

I didn’t ask for proof.

Can I find out more about these rumors somewhere?

The mirrors are the not the expensive part.

In your example what happens if the shirt is sold to someone else? In the NFT case the signature changes.

The shirt analogy doesn’t work well, but NFTs are great for transferable tickets.

However NFTs were trying to assign value to the receipt for the Gretzky shirt.

neither has any plans to accept the other’s NFTs.

However, NFTs that are accepted by both will have higher value.

but the game itself doesn’t care.

We are starting seeing this on Roblox and Fortnite where skins can pass through to different games. .

As soon as either company crashes and goes bankrupt, everything connected will become useless and lose most or all value. Thus, blockchain wouldn’t fix the issue.

That’s exactly what blockchain is fixing. E.g. Your valuable skins don’t disappear when the company running the game you play goes bankrupt.

That’s the theory. Games companies are at the private blockchain stage but there are some small web3 game developers.

Steam cards are a good example. Imagine if stream went bankrupt. Wouldn’t be an issue with Blockchain.

Facebook started as invite only. Great for an exclusive, loyal customer.

NFTs are different to blockchain, so you’re just muddying the waters for yourself with the Walmart thing

Each item is represented by an NFT on the Walmart blockchain. The innovation in the chain of custody is that everyone is verifiably using the same database. It’s a permissioned database, so it’s proof of authority.

Private keys sign hashes. Hashes cannot sign hashes because there is no associated private key.

The legal system needs to enforce ownership and recognise the blockchain as the official ownership registry.

It’s one example of NFTs in real business. Need more?

• Walmart tracks their supply chain using blockchain.
• Starbucks loyalty scheme is NFT based

Previously you’ve not been able to transfer tickets without third party help. Nor could issuers participate in the profits in the secondary market.

Nfts will creep in slowly as efficiency gains are realized. They are already being used for airline tickets.

Is this practical? How technically difficult is it? What are the hardware requirements?
