1. is BCC use a different public key/ address format than BTC?
No. They are using the same underlying technology for private/public keys... ie. ECDSA. At the moment, the only differences are the "consensus rules"... whereby BCH is allowing up to 8MB blocks... and in the transaction signing algorithm which was done to prevent "Replay Attacks"... (ie. BCC transaction is not valid on BTC chain, and BTC transaction is not valid on BCC chain)Quote
2. when I use a address generator like paper wallet to generate a bitcoin address / public key, is the bitcoin or BCC network aware of this address? or until I use it?
Technically, all addresses already exist... as they're just very large numbers. Having said that, until an address is used in a transaction which is then broadcast and confirmed, there is no record of it on the blockchain.Quote
3. if BCC address and BTC address is same, does it means I can use a BITCOIN paper wallet to generate a paper wallet and use it on BCC network?
Yes.Quote
4. if question 3 is false, where can I find a paper wallet generator and an wallet app that shows or support import address from public/private key pair.
See #3.Quote
5. is there a web site like https://blockchain.info for BCC network?
So far, I have found:Blockchair: https://blockchair.com/bitcoin-cash/blocks
Blockdozer: http://blockdozer.com/insight/
Thanks so much for the detail.
now I feel more confident.
