Detailed Project Description (no more than 3-4 sentences)

HashD is a command line tool that can create an identity by generating two key pairs, the first signs a block. The other is output a mnemonic which is stored offline only, this is can be used to recover a hacked or lost account. To broadcast a message a new block added to an id's chain with proof of work attached. This reduces gossip spam by tying it to a single identity and adding cost to producing messages that propagate widely. To add more immutability, these chains are timestamped into bitcoin(not implemented)

Describe your tech stack (e.g., protocols, languages, API’s, etc.)

We have two partial implementations one in Rust and one in Python, mainly using indy-crypto library for BLS signatures, and uses BIP39 mnemonic
