Description (written by the developer; not a statement by this register)
Test place to push SLVM to its limits! SLVM is a sandboxing utility to run untrusted code on the server. SLVM allows you to make your own rules at runtime. SLVM is based on FiOne (a better version of LBI, aka Lua Bytecode Interpreter) and operates inside the Virtual Machine's instructions such as GETGLOBAL and GETTABLE. Any vulnerability (sandbox evasions) should be disclosed to the ASense Communication Server. Known Blocked Attacks: - Sandbox Evasion (EX: Spawning a part in workspace) - Server Crasher (JMP, FORLOOP, TFORLOOP) - Console Spam Crasher (string.rep) SLVM Global: - SLVM_ALLOWED_INSTANCE (A folder located in workspace. It is EXTREMELY restricted! Made for Instance behavior testing) Shutdows are frequent. They are most likely due to updates. Blocked globals (set manually via the SLVM Api): require, getfenv, setfenv, Stats, stats, UserSettings, printidentity, Instance, game, workspace, task.synchronize and desynchronize

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
