+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.
