Not sure if this exists but digital privacy awareness apps and mini games for educating people. (graphical content)

Self-sovereign identity, with granular information sharing, and good encryption/signing support. I want to:

• be able to create ad-hoc identities
• own my identities independent of any third-party provider
• be able to slice identity information and selectively share subsets of possibly signed data
• cryptographically attest other peoples shared data
• have all of this on blockchain, rather than depending on service providers

There's a fair amount of almost solutions, and except for blockchain, nostr has most of the necessary structure. What's missing is a NIP for an identity/profile data format standard, and a spec for data handling. But mainly, apps that make it easy to use, to publish, to verify and validate, and to authorize.

I'm sick of having hundreds of distinct identites scattered around the internet. Having the option to be anonymous or a distinct persona is important, but it shouldn't be necessary every time, and I should always be the owner of that identity.

A good note taking application kinda like Joplin but where I can draw over the text notes without having to draw in a separate program and then Import it as an image. I want to take notes while in class, so it should be fast to begin drawing.

Features:

• able to draw
• Sync with my other devices (Linux laptop and desktop) preferably via my nextcloud instance.
• Place images where I want and not just on its own line
• Supports latex or katex
• Syntax highlighting for code
