  • Privacy is Security
Jarrad Hope

Jarrad came to Bitcoin in early 2011 through agorism, counter-economics & crypto-anarchy, seeing that Bitcoin could operate a monetary policy in a hostile environment, he began to view public blockchains as a voluntary social order, one that didn’t depend on a monopoly of violence. From there he participated in early attempts to generalise the bitcoin script to advance institutional libertarianism, ultimately becoming an early contributor to Ethereum. While Jarrad advances privacy technologies through developing an e2e and p2p private messaging client & super app, Status, he realised that privacy technologies are not enough and now is advocating for self-sovereign crypto-networks, the realisation of a latent cypherpunk dream, the crypto-state.

The TAM project was initiated as a Parallel Polis internal solution to the centuries-old question: "How do I store my crypto for inheritance?".
