Hanzo Hasashi

Security-focused platform engineer building high-trust infrastructure for HPC, core systems, and digital-asset platforms.

Focus

  • HPC + platform security (multi-tenant isolation, scheduler/runtime hardening)
  • Confidential computing + attestation-driven trust boundaries
  • Bitcoin custody and key-management architecture
  • Threat modeling and production security controls

Current Direction (2026)

HPC + Core Engineering + Security + Platforms

I’m optimizing for principal-level infrastructure security work where performance, reliability, and security constraints all matter at once.

Selected Projects

attested-custody
Attested threshold custody architecture (whitepaper + Go reference implementation + STRIDE model).

btc-custody
Threshold-signing custody prototype with policy controls and HSM integration.

lnaudit
Lightning infrastructure security auditing with automated checks and remediation guidance.

terraform-aws-bitcoin-enclave-node
Hardened Bitcoin Core deployment path with Nitro Enclave integration.

secure-infra-roadmap
Public roadmap for the HPC/platform-security trajectory.
