Subject: Re: [bitcoin-dev] Custom signet for testing full RBF
Precedence: list

Hi alicexbt

Thanks for setting this up. Generally it seems to me like an excellent idea=
 to set up custom signets (and/or get proposals enabled on the default sign=
et) for testing and experimenting with new proposals.

I have two questions.

1) In this particular case the -mempoolfullrbf configuration option is in t=
he recent Bitcoin Core 24.0 release and so can be used both on mainnet and =
the default signet, testnet etc. What could be tested on this custom signet=
 that can't be tested on the default signet with Bitcoin Core 24.0? Perhaps=
 there are some things that are easier to test with a smaller custom signet=
 network starting from scratch?

2) I know a number of people have struggled (e.g. [0], [1]) to get a custom=
 signet set up. I think the CTV signet took a while to get set up too. It s=
eems you followed the instructions on the Bitcoin wiki [2] for setting this=
 one up? Was there anything you found difficult or was counterintuitive get=
ting this custom signet set up? You are the sole block signer on this custo=
m signet. How regularly are you mining blocks (e.g. strictly every 10 minut=
es, replicating the Poisson process on mainnet, adhoc etc?) Are you running=
 this custom signet node on the same machine as a default signet, mainnet, =
testnet full node? I'm a little tentative to start joining custom signet ne=
tworks on the same machine that is already running other nodes but perhaps =
there are no problems.=20

I'm not sure yet if I have a use case in mind for this particular custom si=
gnet but I'm very interested in custom signet setup generally and the docs/=
resources to make this as easy as possible so thanks again for posting abou=
t this.

Thanks
Michael
