Why dual-anticheat architecture works best

Ecstacy is not a traditional simulation anticheat and never tries to be. Movement hacks (Fly, Speed, NoFall, Phase) are solved geometrically by server-side tick simulation engines like GrimAC and Vulcan.

In contrast, combat automation (Crystal Aura, Anchor Macro, Auto Totem) is an adversarial timing and behavioral problem that simulation cannot solve without severe false bans against tier-1 PvP players. Running Grim or Vulcan alongside Ecstacy is the optimal architecture: let the movement engine manage movement flags, while Ecstacy protects combat integrity with 99.9% precision.

Network proxies, ViaVersion, and Geyser placement

On a proxy network (Velocity / BungeeCord), player packet timestamps and combat sequences are processed on the backend game servers, not the proxy.

Always ensure that ViaVersion and Floodgate / Geyser are installed directly on each backend Paper/Folia instance in addition to any proxy installation. This guarantees that inbound client packets are translated into normalized 1.21 protocol form before reaching PacketEvents and Ecstacy's telemetry collectors.

Zero open ports & network firewall requirements

Ecstacy dials outbound over TLS to our scoring cluster at cloud.ecstacy.ac:5001. It never binds to local ports and never listens for inbound connections.

You do not need to open, forward, or configure any ports on your firewall or hosting provider. If your host blocks arbitrary outbound TCP traffic, simply allow outbound connections to port 5001.
