Steven Noni Feb 16 · 6 min read Over the past few months, we’ve built a prototype, hosted a hackathon, hired a whole new team, specced out RPCh as a service to give wallets (and users) their first private blockchain gateway, and built a sandbox version to show that it was all feasible. If that … Read more
Steven Noni Feb 1 · 6 min read We returned from Colombia with a new team and a new drive. RPCh would be the first product on top of HOPR — a clear use case for the protocol which didn’t just provide a vague privacy upgrade but which solved an urgent and timely problem in … Read more
