Zallet is my first blockchain project with a wallet. I wrote it in zig and used Ed25519 Signing to encrypt transactions between wallets. I used Sha256 to hash the blocks on the chain. I used the proof by work method to verify blocks on the blockchain.
3D Flight Map is a flight statistics viewer with graphs, queries and a 3D globe that displays the airports and flights all around the world.
