Fault-Tolerant Data Feed Architecture

We design and implement redundant, multi-source oracle architectures with automated failover and Byzantine fault tolerance, guaranteeing data availability and integrity for mission-critical financial or operational contracts.
Chainscore © 2026
overview
RELIABLE FOUNDATION

Blockchain Infrastructure & Node Management

Enterprise-grade node infrastructure with 99.9% uptime SLA for mission-critical Web3 applications.

We architect and manage your core blockchain infrastructure, eliminating the operational overhead of running nodes in-house. This includes multi-cloud deployment, automated failover, and real-time monitoring for chains like Ethereum, Polygon, Solana, and Avalanche.

  • Dedicated, Bare-Metal Nodes: Full control and performance, not shared resources.
  • RPC & API Endpoints: High-availability access with load balancing and rate limiting.
  • Archive & Tracing Nodes: Full historical data for analytics and indexing.
  • Validator Management: Secure staking operations with slashing protection.

Focus on building your product. We guarantee the foundational layer with predictable costs and enterprise SLAs.
