Midnight on Arkhia — Q1 2026​

March 2026

Arkhia now supports the Midnight network — a privacy-focused Layer 1 blockchain built on zero-knowledge proofs. Enterprise clients can access Midnight ZK-PaaS and Midnight RPC endpoints through Arkhia, with granular per-project controls for advanced ZK features.

Proof Server Version

Current Proof Server: v7.0.0

🚀 What's New​

🌙 Midnight ZK-PaaS Endpoints​

Zero-knowledge proof infrastructure via the Midnight ZK-PaaS service.

Endpoints:

  • POST /prove-tx — Submit a single ZK transaction proof
  • POST /prove-batch — Submit up to 20 proofs in a single batch request

Details:

  • Available on Preprod — Mainnet coming soon
  • Binary validation applied to prove-tx payloads
  • All requests require a valid Arkhia API key scoped to a Midnight ZK-PaaS project

🔗 Midnight RPC Endpoints​

JSON-RPC node access for querying the Midnight blockchain state.

Supported Methods:

  • Chain info queries
  • Ledger version queries
  • API version queries

Details:

  • GET and POST method support
  • Available on Preprod — Mainnet coming soon
  • Request usage tracked separately from ZK-PaaS in the credit system

💸 Sponsored Wallet​

Automatic DUST token gas fee management for Midnight transactions.

Details:

  • Enable per-project from the ZK Project Settings panel in the dashboard
  • When enabled, DUST token fees are paid automatically — users no longer need to hold or manage DUST tokens
  • Controlled via the sponsored request header in the Arkhia proxy
  • Password-protected toggle; changes propagate within 30 minutes

⚡ ZK Prove Batch​

High-throughput batch proof submission for production ZK pipelines.

Details:

  • Submit up to 20 ZK proofs per request via /prove-batch
  • Enable per-project from the ZK Project Settings panel
  • Requests exceeding the 20-proof limit are rejected with a clear error message
  • Password-protected toggle; changes propagate within 30 minutes

🔒 Relay to Confidential Space (Preview)​

Route transactions to a secure, isolated compute environment for maximum privacy.

Details:

  • Transactions are relayed to a sandboxed confidential environment
  • Provides an additional privacy layer beyond standard ZK proofs
  • Controlled via the zk_relay_to_space per-project setting
  • Currently available as a preview feature — disabled by default; contact support to enable

⚙️ ZK Project Settings UI​

New per-project settings panel in the Arkhia dashboard for managing all Midnight-specific features.

  -H "Content-Type: application/octet-stream" \
  --data-binary @proof-payload.bin
# Prove a batch (up to 20 proofs) — requires Prove Batch to be enabled
curl -X POST "https://arkhia.io/midnight/zkpaas/<API-KEY>/prove-batch" \
  -H "Content-Type: application/json" \
  -d '{"proofs": [...]}'
