Architecture
The Icelite Solution
Native packet interception paired with deterministic physics simulation. Zero lag, zero false bans.
1. Low-Level Netty Packet Interception
Icelite hooks directly into Netty's channel pipeline before packets reach the Minecraft main tick loop. Illegal combat packets are cancelled instantly in sub-millisecond time.
Evaluated asynchronously across dedicated worker threads with zero main-thread TPS drop.
2. Deterministic Vanilla Physics Engine
Simulates the exact vanilla Minecraft movement formulas to eliminate false flags:
- Ground friction calculation based on block type (Ice, Slime, Soul Sand).
- Inertia decay and gravity acceleration tracking per player tick.
- Precise bounding-box raycasting against player position history buffers.
Combat checks compute exact mathematical line-of-sight to prevent bypasses without hindering legitimate PvP mechanics.
3. Cloud Heuristics & Replay Profiling
Complex pattern detection runs out-of-band on isolated threads and cloud heuristic clusters.
Suspicious patterns are evaluated across thousands of ticks. Sudden bursts, rotation irregularities, and click jitter are cross-referenced with millisecond accuracy.
4. Proxy-Aware Multi-Server Synchronization
Whether running standalone Paper servers or a 100-instance Folia network behind Velocity or BungeeCord, Icelite synchronizes player violation data across nodes in real-time.
Staff alerts, automated freezes, and Discord webhook notifications fire across all lobbies simultaneously.
