Obsidian

I would signup for sync yearly and get the catalyst license if I could pay with crypto

/obsidian is so close, it has "credits" you can buy but only with a credit card

Took 20-30 minutes to setup git for sync for Obsidian

Working Copy app on iOS/iPadOS for version control and SSH id management (nice auto-commit on file-edit)

Honestly this takes a bit of effort, but it's free and works great.
