hashmeme

It's the year 2099 and historians are debating who first published this and that meme.

If only there was a system that could trace origins of memes...

Introducing HashMeme, a tool for keeping an immutable logs of memes using Hedera services.

Nix Installation (optional)

This uses nix to get a development environment up.

This is optional but highly recommended to get up a reproducible development environment.

For more detailed instructions for your system see: https://nixos.org/download.html

make install

Start nix daemon

Start a daemon in one terminal window

sudo /nix/var/nix/profiles/default/bin/nix-daemon

Start a nix-shell

This is your development environment

nix-shell --pure

Building

make build

# Check ./target for runnable

Making a GUI frontend

make gui

# or if not using nix:
make gui-nonix

Running tests

make tests

How it works

• User saves keys locally in a .env file
• User provides an image path as an input.
• HashMeme creates a hash of the image.
• HashMeme also tries to detect the text with OCR.
• HashMeme sends the payload of (Author,ImageHash,TextContent)to the Hedera Consensus Service
• Any user can then look up against the HCS based against the content.

FAQ

Some design decisions were taken that can be answered by the following:

Why Go?

• It's simple, efficient, stable
• The UI framework can compile to native binaries across MacOS, Windows, Linux, Android, and iOS.
• ..and it's got an official SDK with Hedera.

Why run locally?

• It's a simple implementation and your keys remain safe locally (assuming you know how to keep your local files secure).
• Maybe in the future there could be a wallet integration once that is more mature.

Why did you choose the Hedera Consensus Service? Why not the Hedera Token Service or the Hedera File System to store memes?

• The Consensus service is a lot cheaper with predictable fees, which you can read more about it here: https://docs.hedera.com/guides/mainnet/fees#transaction-and-query-fees
• Current ownership isn't what we're solving for as with an NFT, we just care about when did this meme first appear out in the wild.
• The consensus service is a better fit when it comes to arriving to an agreement when a certain thing first appeared. In this case, it's a hash of an image with it's text content in the field.

Ok this is silly isn't it?

• Yeah, it is mostly for the lols, but it's a proof of concept of what you can do with the consensus service.
• There is a widespread problem of misinformation and fact checking out there.
• This use case can be extended for verifying facts in the real world.

How can this be extended?

• Native wallet integration
• Support for video formats
• Support for more image formats
• Web version
