I thought people used on-chain and Web3 as synonyms, because it is obvious all crypto casinos (decentralized or centralized) are supposed to use on-chain transactions in order to carry out deposits and withdrawals...
I could not imagine a crypto casino which would not be off-chain, it does not make sense at all, in my opinion.
That is the kind of terminology mistake which I would expect from newbies who don't know the differences between centralization and decentralization...
I didn't understand anything, how does this mess work? using metamask?
so what changes compared to traditional casinos
I really racked my brain trying to understand, but an example would be useful to understand a mess like this, does anyone have a screenshot?
It is not actually so difficult to understand. You take a wallet like Meta mask (installed extension on your internet browser) then get to the casino website.
Instead of using a password and username to log in you are supposed to use your wallet address instead, Metamask will automatically sign a message so the casino will know the person accessing their website is also in control of the address and funds in that wallet.
Games are not run on the servers of the casino, they run on the Blockchain instead, on a smart contract. Meaning instead of depositing funds to the casino itself, one deposits to the smart contract in order to play. If there is profit for us, the smart contract send us money back automatically.
That it is basically a very simplified explanation on how it works...
