Vuvuzela: private messaging system that protects metadata
Vuvuzela seems great except your anonymity is guaranteed by a set of high availability and capacity servers.<p>Those servers need to independently operated and resistant to global compromise.<p>We don't really have a good template for a system like this. We have centralized HA systems and decentralized high churn systems like Bittorrent and Tor.<p>I've been intrigued by the observation that forthcoming "proof of stake" blockchain systems have very similar requirements in terms of availability and capacity to anonymous messaging systems. I wonder if we can use the nodes in a PoS system to bootstrap an anonymity system like Vuvuzela.
