Software protection. 136µs startup overhead. Zero hot-path impact.
Per-build uniqueness. Analysis-resistant by design. Angr ran 53 automated analysis steps in 0.4 seconds. Zero keys found. The challenge is open.
Execution passes through three virtual machine layers sequentially. Static analysis sees a different surface at each layer.
Protection is not a gate around the computation. It is part of the computation. Removing it produces wrong answers.
RDRAND shuffles opcodes at build time. Every customer binary is structurally distinct. A working crack on one build is useless on another.
Produce a 64-character hex key that causes the unmodified binary to print LICENSE VALID. Binary patching does not count. The key must generalize. Per-build RDRAND opcode shuffles mean each binary is unique. A patch on this build transfers nowhere.

One call at startup. Your code runs unchanged.
// Initialize once at startup
lacuna_init("your-license-key");
// Your code runs unchanged
void process_data(Data* d) {
// Zero overhead here
d->compute();
