Swarm-based parallel probing with cryptographic consensus
"Security through consensus, not configuration."
|
BLSMESH combines two powerful paradigms:
The result is a pure Rust, single-binary security research tool where specialized agents probe LLMs for vulnerabilities, with findings emerging through cryptographic consensus. |
|
BLSMESH is a distributed adversarial security evaluation framework for Large Language Models. Instead of running attacks sequentially, a swarm of agents probes the target in parallel, with findings emerging through cryptographic consensus rather than central orchestration.
