Overview#

During a major ransomware investigation, an analyst needed to query archived Bitcoin transaction data going back three years without relying on a third-party API that might rate-limit or log the request. A self-hosted full node provided that data with complete sovereignty, no external dependencies, and sub-second response times for the investigation's most sensitive queries. That kind of infrastructure control matters when the stakes are high.

The Blockchain Node Infrastructure module delivers enterprise-grade node management across multi-chain blockchain operations. It continuously monitors blockchain nodes across multiple networks, tracking sync status, block height, peer connections, and response latency in real-time. When nodes fail or performance degrades, routing algorithms automatically redirect traffic to healthy endpoints with no manual intervention required. This infrastructure underpins every other blockchain module, ensuring investigations are never blocked by connectivity issues.

Key Features#

  • High-Availability Architecture: Redundant node infrastructure with automatic failover ensures continuous blockchain data access across all supported networks
  • Intelligent Health Monitoring: Continuous monitoring of sync status, block height, peer connections, and response latency with predictive health scoring to identify failing nodes before complete outage
  • Automatic Failover: Traffic automatically redirects to healthy endpoints within seconds of detecting node degradation, with no manual intervention required
  • Multi-Provider Strategy: Hybrid approach combining self-hosted nodes with reliable providers to optimise cost, performance, and data sovereignty
  • Load Balancing: Distributes query traffic across node pools based on health scores, latency, and capacity to maintain optimal performance
  • Multi-Network Support: Manages node connectivity across major blockchain networks from a unified management layer
  • Sync Monitoring: Tracks blockchain synchronisation status across all nodes with automated alerting for sync lag or data staleness

Supported Networks#

  • Self-Hosted Full Nodes: Bitcoin (complete blockchain history for sovereign investigation capabilities)
  • Major EVM Networks: Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, Base, Avalanche, Fantom, Gnosis
  • Layer 2 Solutions: zkSync Era, Polygon zkEVM, Scroll, Linea, Mantle, Blast, and more
  • Non-EVM Networks: Solana, Tron, Sui, Aptos, Near, TON, Cardano
  • Additional Chains: Cronos, Moonbeam, Aurora, Celo, and dozens more

Infrastructure Capabilities#

Node Health Monitoring#

  • Real-time tracking of node sync status, block height lag, and response latency
  • Predictive health scoring identifies degrading nodes before they impact service
  • Automated alerting when nodes fall behind chain tip or exhibit anomalous behaviour

Failover and Redundancy#

  • Automatic failover to healthy nodes when primary connections degrade
  • Multi-region redundancy ensures availability even during regional infrastructure disruptions
  • Graceful degradation with cached data when temporary connectivity issues occur

Performance Optimisation#

  • Intelligent query routing selects the optimal node based on latency, health, and data availability
  • Caching architecture reduces redundant blockchain queries and improves response times
  • Batch request optimisation minimises round-trip overhead for bulk operations

Data Sovereignty#

  • Self-hosted Bitcoin full node provides complete blockchain history without third-party data exposure
  • Configurable node selection policies allow organisations to control data routing preferences
  • No dependency on any single external provider for critical investigation data

Investigation Use Cases#

Continuous Investigation Support#

  • Reliable blockchain data access ensures investigations are never blocked by infrastructure issues
  • High-availability design means real-time monitoring and alerting continue without interruption
  • Archive node access provides complete historical data for deep forensic analysis

High-Volume Transaction Analysis#

  • Enterprise-grade throughput supports high-volume transaction screening and compliance operations
  • Load balancing prevents query bottlenecks during peak investigation activity
  • Batch processing capabilities enable efficient bulk address and transaction analysis

Cross-Chain Operations#

  • Unified node management simplifies multi-chain investigation workflows
  • Consistent data quality and availability across all supported networks
  • Automatic handling of chain-specific node requirements and configurations

Open Standards#

  • JSON-RPC 2.0: All communication with EVM-compatible blockchain nodes uses the JSON-RPC 2.0 wire protocol, including direct node calls for methods such as eth_blockNumber, eth_getBalance, and eth_getTransactionReceipt.
  • Ethereum JSON-RPC API (EIP-1474): The infrastructure exposes and proxies the standard Ethereum execution-layer JSON-RPC method set (eth_*, net_*, web3_*) across all 16 supported EVM networks, ensuring client compatibility regardless of which node handles the request.
  • EIP-155 (Replay Attack Protection / Chain ID): Every EVM chain is identified and routed by its canonical numeric chain ID (e.g., 1 for Ethereum Mainnet, 137 for Polygon), as standardised in EIP-155, preventing cross-chain transaction replay.
  • ERC-20 / ERC-721 / ERC-1155: The node layer stores and serves token transfer events conforming to these Ethereum token standards, enabling higher-level modules to query fungible and non-fungible asset flows without additional normalisation.
  • Bitcoin P2P Network Protocol (BIP standards): The self-hosted Bitcoin full node participates in the Bitcoin peer-to-peer network, implementing the serialisation formats and consensus rules codified across the relevant Bitcoin Improvement Proposals (BIPs) to maintain a complete, sovereign copy of the chain.
  • TLS 1.3 (RFC 8446): All data in transit between the node infrastructure and consuming services is encrypted using TLS 1.3, as stated in the compliance section of the module.
  • ISO 8601: All timestamps produced by the node monitoring, health scoring, and query-response pipeline are serialised in ISO 8601 format, ensuring interoperability with downstream investigation and audit systems.

Compliance#

  • Self-hosted node options support data sovereignty and residency requirements
  • Infrastructure designed for enterprise reliability with high-availability guarantees
  • Complete audit logging of all node operations and data access
  • Encryption for data in transit (TLS 1.3) and at rest
  • SOC 2 Type II certified infrastructure
  • Cloud-agnostic architecture supporting diverse deployment requirements
