Shardian

Building high-assurance infrastructure for hostile networks.

We specialize in hardened P2P fabrics, applied cryptography, and low-level C++20 performance. We operate where determinism, temporal security, and resilience matter more than surface polish.

Engineering philosophy

Shardian tackles problems that force you to drop to the kernel, design modern cryptographic primitives, and optimize every cycle to preserve correctness under adversarial conditions. Our culture pairs academic rigor with pragmatic execution: we ship invisible engines that keep running when the rest of the stack collapses.

EphemeralNet

EphemeralNet is a secure, ephemeral C++20 P2P network with a proprietary relay that pierces hostile NATs and renegotiates routes in milliseconds. It is built for sensitive workloads that demand anonymity, low attack surface, and cryptographic consistency.

  • Dynamic topology with deterministic discovery and bounded latency.
  • Integrated relay/turn stack for environments guarded by aggressive firewalls.
  • Ephemeral, end-to-end encrypted sessions with automated key rotation.
