Zodl Begins OHTTP Rollout to Shield Zcash Wallet Users’ IP Addresses

Zodl, a Zcash (ZEC) wallet, began a Nov. 9 rollout of infrastructure that routes wallet requests through relays, keeping users’ IP addresses from the ZODL servers that process them.

The system uses the IETF’s Oblivious HTTP (OHTTP) standard. A Cloudflare or Fastly relay can see a user’s IP address but cannot read the encrypted request. ZODL processes the request without the originating IP, so its servers cannot directly connect the request to that address.

Zodl previously relied on community-operated lightwallet servers. The new infrastructure is rolling out gradually on Android and iOS over the week following Nov. 9. F-Droid and GitHub releases are expected later this week. Users need version 3.20.0.
