Hello World,

I was working on an intern project in last few weeks which is almost ready =
for first release. Will be helpful if devs working on Bitcoin Core and .NET=
 projects related to Bitcoin can share feedback. Pieter Wuille and Luke Das=
hjr had already shared few things before I started working on this project =
which wasn't really positive considering the use of .NET and PowerShell in =
this project. I respect their opinion and agree we could make better applic=
ations however I have tried my best to express the goal I am trying to achi=
eve with this project below.

Project repository:=C2=A0https://github.com/prayank23/bitcoin-ps

Other details about related milestones:=C2=A0https://github.com/BlockchainC=
ommons/Community/discussions/51

Project is inspired by Burp Suite and I want to create a similar applicatio=
n which is only used to test privacy and security of Bitcoin Core RPC using=
 GUI. I used WPF instead of Avalonia right now to save time. I will use it =
in future to make bitcoin-ps cross platform, most of the code will remain s=
ame and I have shared a proof of concept in milestones link above in which =
application works fine on Ubuntu with no pwsh installed. Hopefully this iss=
ue will also be resolved soon:=C2=A0https://github.com/AvaloniaUI/Avalonia/=
issues/4361

Default scripts:

1.CPU_RAM_sendtoaddress.ps1 : Check CPU and RAM usage while using some wall=
et RPCs multiple times. Results for Ubuntu and Windows were interesting. Fo=
r some reason it almost used 100% CPU in Ubuntu.

2.onlynet_i2p.ps1 : Outbound connections are made to onion peers while only=
net=3Di2p is used without any proxy

3.lock_unspent.ps1 : Check if locked UTXOs are unlocked on restart

4.custom_change_rbf.ps1: Compares the inputs for Tx1 and Tx2 where Tx1 is R=
BF transaction with 1 input, 2 ouputs (custom change address with label), T=
x2 is replacement transaction

Why PowerShell?

1.I have worked on 2 similar projects in past: A basic application for Offi=
ce 365 admins and support engineers and One project related to Infosec.
2.Testing using different languages locally doesn't impact Bitcoin Core or =
require any changes.
3.Easier to write and devs who use PowerShell scripts in their projects cou=
ld relate to it, find interesting and maybe start contributing to Bitcoin C=
ore.
4.It can be done using bash or maybe python scripts as well. For me using P=
owerShell in this project is like meeting a college friend and exploring ne=
w places.
5.PowerShell Core is open source and works on Linux, Mac etc.

Last but not least, I would like to thank Christopher, Vinay, guests in mee=
tings, other interns and everyone involved in Blockchain Commons. I have le=
arnt lot of new things during internship. Would suggest everyone to start w=
ith 'Learning Bitcoin from the Command Line' if they have recently started =
reading about Bitcoin. I wish I could do more projects, will work on DEX an=
d OfflineTx even after internship ends to complete by end of this year.
