I see more ICO are complying with KYC. I wonder what exactly means for the crowdsale smart contract. Is the latter rejecting eth coming from unregistered addresses? Then, how is this managed? With a huge table inside the crowdsale?

Thx for any clue.

Yeah, that's what it usually is. If you check the source of the Raiden crowdsale contract, what you're looking for is the functionality around the array whitelist, as that is where they stored their KYC verified contributors.
