The monitor thread read the core's merged stdout/stderr and dropped
every line:
process.inputStream.bufferedReader().use { reader ->
reader.forEachLine { _ -> }
}
so the only trace of a core that died at startup was "Xray process
exited with code 23", with nothing to say why. That exit is real and
intermittent - it showed up on both a handset and an emulator - and
was undiagnosable in the field.
Keep at most 40 lines, and only from the core's first 10 seconds, then
log them when the exit code is non-zero. A core up longer than that may
be carrying traffic and its log can name destinations, which must never
reach the device log (rule 95), so past the window the buffer is
dropped rather than kept.

ReVoltVPN
A free VPN app for Android. Open-source client, transparent infrastructure. Watch an ad, get 2 hours of full-speed traffic — no accounts, no logs, no subscriptions.
How it works
- Watch a short rewarded ad
- Server creates a temporary VLESS session (2 hours / 10 GB)
- Your traffic routes through a single server in Finland at full speed
- When time or data runs out, session ends — watch another ad to continue
- No throttling, no slow lane, no mid-session punishment
No email. No password. No payment. The ad pays for the server.
Protocol
- Transport — VLESS over XHTTP (HTTP/2 multiplexed, path-hidden behind
/revolt) - Obfuscation — Xray Reality spoofs a real website's TLS. To any DPI box, your tunnel looks like a browser visiting that website
- Encryption — TLS 1.3 with borrowed certificate (Reality). No certbot, no domain ownership required
- API — Standard HTTPS to a separate domain. Tunnel destination is IP-pinned — domain compromise is DoS only
Stack
| Layer | Technology |
|---|---|
| App | Flutter (Android) |
| VPN | VLESS + Xray Reality + XHTTP |
| Backend | Python Flask ("Hivemind") — session management, quotas, stats |
| Ads | Google AdMob rewarded, verified server-side |
| Server | Debian, single Hetzner box in Finland |
Limitations
- One server, one location (Finland)
- 2 vCPU / 4 GB RAM — not built for thousands of concurrent users
- Android only
Privacy
Your traffic routes through Finland. We don't log it, inspect it, or sell it. Hivemind tracks only session liveness and byte counters for quota enforcement — no packet contents, no destination IPs, no DNS queries.
