how does bitcoind functions in bitcoin exchange model?

how does bitcoind functions in bitcoin exchange model?

i mean exchange allows every users a unique BTC deposit address

different users sends btc to different addresses but BTC endsup in same wallet

can i create multiple receiving address by bitcoind (getnewaddress) or i will have to use HD wallet for that for our users (we are building lotto system on bitcoin)

bitcoin node: what is the difference between simnet and regtest?

bitcoin node: what is the difference between simnet and regtest? btcd, and presumably other bitcoin node implementations, seem to have 4 network options: mainnet testnet regtest simnet. I get that mainnet and testnet both are "public" in that your node will communicate with other nodes and that both have an existing blockchain and genesis block. However, from what I can tell, both simenet and regtest both create a local only blockchain, and both will create a new genesis block. I this case, what is the difference, and which is better (easier) for developing bitcoin applications? This is what the documentation has to say: --regtest Use the regression test network --simnet Use the simulation test network https://ift.tt/2TAMkwe

How to check if Electrum is masking my IP with the Tor proxy?

How to check if Electrum is masking my IP with the Tor proxy? When i start Electrum from the command line i see this mensage: (python3:7069): dbind-WARNING **: 14:09:58.452: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken What does it mean?

When mining with 2 computers, do I need to use 2 separate wallets addresses?

When mining with 2 computers, do I need to use 2 separate wallets addresses? I understand that each miner is working on a different block. Correct me if I'm wrong but this is because the first transaction in a block basically contains my wallet address so I can receive the bonus of solving the block. Obviously everyone wants to receive the bonus so that first transaction will be pointing to everyone's separate wallet addresses. Assume that I have two computers solo mining with both pointing to my wallet address, wouldn't this mean my computers are solving the same block? Continuing with this train of thought, wouldn't that mean that my slower computer is basically useless because it would be generating the same hashes as my faster computer? Now how does this apply to pooled mining? In a pooled community, is everyone solving the same block which has the first transaction pointing to the pool owner who then distributes the coins? http://bit.ly/2SZOBAI
