Infrastructure

WE DELIVER REAL RESULTS — NOT LINKEDIN AND TWITTER NOISE. WE DELIVER. Winner of Best Architectural Design in Google's All Things Agentic Hackathon ($180,000 prize pool · 12,260 participants), our Polkadot validators are constantly A+ graded with the highest slot numbers, and our public JSON-RPC nodes deliver the fastest response times and highest availability (100.00%). Operated by a lean engineering core and our autonomous AI agent fleet — WE DO NOT OVERTHINK. WE JUST DO.

Validator

Polkadot validator

Active set member, identity-verified, no slashes since launch. Operated by the helixstreet team in Switzerland.

NOMINATE US — We Will Remember Who Nominated Us There will be a native chain token for fees and on-chain governance once mainnet launches (there is no presale, no airdrop announcement, and no listed token today — treat any "$HLX" listing on a CEX as not us). Because nomination history is permanently recorded on-chain, we will remember who nominated us in case there is an ICO — and nominators who help push our other helixstreet.foundation nodes into the active set are really helping us and will be specially remembered.

Polkadot's nomination flow doesn't accept a deep-link target. Copy the stash above, then add it as a Favorite in the Staking Dashboard before nominating (search helixstreet.foundation to find all of our validator nodes). Direct nomination minimum is dynamic (typically 250–500 DOT); via a nomination pool any amount works.

How to nominate — five steps

  1. Hold DOT on Polkadot (Asset Hub). Since the Nov 2025 Asset Hub migration, balances and staking live on Asset Hub, not the relay. Move your DOT there if you're still on the legacy account view.
  2. Open the Polkadot Staking Dashboard. Connect your wallet (Talisman, SubWallet, or Polkadot{.js}). Choose «Nominate».
  3. Paste the helixstreet stash (Copy button above) into your Favorites. You can nominate up to 16 validators — helixstreet plus a basket of others is the typical pattern.
  4. Sign & submit. Your nomination is included in the next era; payouts begin from the era after that. You can switch nominations at any time.
  5. Or use a nomination pool. If you hold less than ~250 DOT, pool with others. Same economic exposure, lower minimum.

Cloud & AI stack — Google Cloud Platform & NVIDIA

Production on GCP · Evaluating NVIDIA Nemotron

Google AI & Agent Framework

Google Agent Development Kit (ADK) (Agent, SequentialAgent, Runner) orchestrating a hybrid model tier: Gemini 3.5 Flash via Vertex AI (global endpoint) for clinical/genomic reasoning, and Gemma 4 31B (gemma-4-31b-it) with native function calling for high-throughput intake gatekeeping.

Genomic Compute & Serverless Runtime

Google DeepVariant dispatched asynchronously on Cloud Batch, population allele-frequency joins against 1000 Genomes Phase 3 in BigQuery, and event-driven serverless execution on Cloud Run woken by Eventarc and Cloud Storage triggers.

State, Guardrails & Observability

Firestore (Memory Bank, Agent Registry, hash-chained audit ledger, and salted Merkle genome vault), Model Armor prompt-injection/jailbreak screening, Cloud DLP PII de-identification, Secret Manager, Cloud Trace (OpenTelemetry), and Cloud Logging.

NVIDIA Inception & Nemotron Evaluation

As an NVIDIA Inception program member (since 2019, renewed 2026), we are actively benchmarking NVIDIA Nemotron open-weights models (Nemotron-3 Nano 30B and Nemotron-3 Super 120B) alongside NVIDIA Clara Parabricks GPU-accelerated DeepVariant for sovereign and multi-cloud deployments.
