The primary limiting factor is memory. As N increases, memory starts to become the most expensive component, whether's it's in a GPU or an ASIC. For example, let's say the memory needed to achieve a certain level of parallelization costs $800. Now a GPU chip costs $400, while an ASIC chip costs $100. So the GPU costs $1,200 overall while the ASIC costs $900. ...
To do an atomic swap, you essentially need two things:
The ability to do 2-of-2 multisignatures. Basically every cryptocurrency supports this, including Bitcoin and Monero, though with varying degrees of ease-of-use. In Bitcoin you can use CHECKMULTISIG opcode; in Monero (and eventually Bitcoin, I hope) you can do 2-party Schnorr signatures which are more ...
You actually don't use the addresses, but the RPC info for the daemons. For example you'd start the pool with the following switches:
python run_p2pool.py --net vertcoin3 --merged http://*RPCuser1*:*LongRPCpass1firstname.lastname@example.org:6888 --merged http://*RPCuser2*:*LongRPCpassemail@example.com:7817
You will see "Got new merged mining work!" in console as confirmation.
Download the official wallet : https://vertcoin.org/wp/get-started/
Then, install it and wait for full sync (aka vertcoin blockchain download)
During the sync, look how to build a simple appropriate vertcoin.conf file which had to be store in the appropriate vertcoin folder (%appdata%/vertcoin in windows)It basically look like this :
