I'm trying to setup a private network of bitcoin nodes for testing and experimentation. From what i understand, i have two choices while setting up a network:
- I can run
bitcoind -testnetand connect to the public test network. The testnet has nodes that will facilitate the mining of my transactions as long as i just broadcast them.
- I can configure the node with
regtest=1and manually run the
generatecommand whenever i want to create blocks.
What i don't understand is how any of these mining softwares interact with the bitcoin node. Does it periodically poll through the JSON RPC to check if the transaction pool has reached a certain threshold (in numbers or size)? If not, what triggers the beginning of a mining operation? Can the bitcoin node send out events when the transaction pool reaches a threshold?
I want to setup a similar automated process for creating blocks in my
regtest network, but using the
generate command instead of any mining software. I don't need a robust PoW setup in my local network. My aim is to just build an app which interacts with the nodes and makes transactions. Is writing an RPC client which periodically queries the pool size and fires a
generate command on reaching a threshold the right way to proceed? Or does the bitcoin node itself provide some way to setup periodic generation of blocks?
Thanks in advance.
P.S. I'm very new to bitcoin development, so apologies if this is an obvious question.
