Hello,

I'm wondering (related to the CryptoBridge shutdown), why it's not sufficient for exchanges (like CB), to just outline in their Terms of Service that they do not accept US/EU customers and are therefore not affected by the AMLD5...

Wouldn't be a simple checkbox at the sign up asking "Are you from US/EU?" enough?
If the user clicks yes, they are not allowed to registered.

Hello everyone,
I'm quite new to the world of crypto and have been wondering, how different blockchains prevent miners/forgers from breaking it.
As far as I know, (in PoS, for instance) a forger get's selected to validate a block of transactions.
But theoretically speaking, he could create different versions of the new block he is validating.

Example:
The miner/forger received 100 transactions and is including all of them in his block A.
Also, he creates a block B that only holds 95 of the transcations.
Now, he broadcasts block A to 50% of the network and block B to the rest.
Both blocks are valid and are signed by him -> he created two different blockchains.


What am I missing / how are do blockchain projects adressing this issue?
Thanks.
