Every VPN has the same weak point: a server that hands out the list of where to connect. Block that one address, and the apps go dark — they can't find a way in anymore. It's the first thing a censor goes after, and it works.
Cascade is our answer. Instead of asking one server for the list, the app reads it from the Solana blockchain.
How it works
The server list lives in a Solana account — encrypted and signed by us. Your app reads it over public RPC, the same infrastructure that powers Solana wallets, NFTs, and payments. There's no single domain to seize and no API to switch off.
- On-chain. The list sits in a Solana account, not on one company server.
- Hard to block. The app rotates through 100+ public RPC endpoints. Block ninety of them and the rest still answer.
- Same tunnel. Cascade only changes how the list is delivered. Your traffic still runs over the same WireGuard and AmneziaWG tunnel.
Blocking every Solana RPC means blocking Solana itself — its DeFi, NFTs and payments. For most censors that's too expensive to be worth it.
What you need to do
Nothing. Cascade is rolling out gradually across iOS, macOS and Windows, and the normal API stays in place as automatic fallback. When the API is reachable, the app uses it; when it isn't, the app reads the chain. You just connect.

Cascade keeps AkcaVPN reachable even when the API gets blocked. See how it works.
