RPC Consumer (Decentralized Mode)

The RPC Consumer is Lava's decentralized RPC gateway that dynamically discovers and pairs with blockchain data providers through on-chain pairing mechanisms. It ensures data reliability through conflict detection, finalization consensus, and multi-provider validation.

When to Use RPC Consumer

Use rpcconsumer when you want:

  • ✅ Decentralized provider discovery - Automatically find and pair with on-chain staked providers
  • ✅ Data reliability - Conflict detection and finalization consensus ensure data accuracy
  • ✅ Dynamic provider rotation - Providers change based on blockchain epochs and staking
  • ✅ Trustless operation - No need to trust specific provider infrastructure
  • ✅ Full Lava protocol features - Access all blockchain validation and incentive mechanisms

For centralized/enterprise deployments with known provider infrastructure, use rpcsmartrouter instead.

Key Features

Decentralized Architecture
  • On-chain Pairing: Discovers providers through blockchain pairing lists
  • Epoch Management: Provider selection updates with blockchain epochs
  • Stake-based Selection: Providers weighted by their on-chain stake
Data Reliability
  • Conflict Detection: Automatically detects and reports provider conflicts
  • Finalization Consensus: Validates data finalization across multiple providers
  • Response Verification: Ensures responses match blockchain state
Advanced Capabilities
  • Provider Optimizer: QoS-based provider selection with multiple strategies
  • Smart Caching: Two-layer caching for improved performance
  • Relay Health Monitoring: Continuous provider health tracking
  • WebSocket Support: Full support for subscription-based APIs

Installation

# Clone the repository
git clone https://github.com/lavanet/lava.git
cd lava

# Install all binaries
make install-all

Configuration

Create a configuration file (e.g., rpcconsumer.yml):

endpoints:
  - chain-id: ETH1
    api-interface: jsonrpc
    network-address: 127.0.0.1:3333
  - chain-id: OSMOSIS
    api-interface: rest
    network-address: 127.0.0.1:3334
  - chain-id: OSMOSIS
    api-interface: tendermintrpc
    network-address: 127.0.0.1:3335
Configuration Fields
  • chain-id: Blockchain identifier (e.g., ETH1, OSMOSIS, LAV1)
  • api-interface: API type (jsonrpc, rest, tendermintrpc, grpc)
  • network-address: IP:PORT where the consumer will listen for requests

Usage

Basic Usage
lavap rpcconsumer rpcconsumer.yml \
  --from wallet_name \
  --chain-id lava-testnet-2 \
  --geolocation 1
Required Flags
  • --from: Your wallet name (used for signing relay requests and conflict detection)
  • --chain-id: Lava blockchain chain ID (e.g., lava-testnet-2, lava-mainnet-1)
  • --geolocation: Your geographic location code
Common Options
lavap rpcconsumer rpcconsumer.yml \
  --from wallet_name \
  --chain-id lava-testnet-2 \
  --geolocation 1 \
  --cache-be "127.0.0.1:7778" \
  --strategy latency \
  --metrics-listen-address ":7779" \
  --log_level debug
Strategy Options

Choose provider selection strategy with --strategy:

  • balanced (default) - Balance between all factors
  • latency - Prioritize fastest providers
  • sync-freshness - Prioritize most up-to-date providers
  • cost - Optimize for lower cost
  • privacy - Maximize privacy
  • accuracy - Prioritize data accuracy
  • distributed - Distribute across many providers
Advanced Flags
# Enable caching
--cache-be "127.0.0.1:7778"

# Prometheus metrics
--metrics-listen-address ":7779"

# Kafka analytics
--relay-kafka-addr "localhost:9092"

# Optimizer QoS reports
--optimizer-qos-server-address "http://qos-server:8080"

# Debug options
--debug-relays
--log_level trace

# Performance tuning
--max-concurrent-providers 5

Example Requests

After starting the consumer, make RPC requests to the configured endpoints:

# REST API request
curl http://127.0.0.1:3334/cosmos/base/tendermint/v1beta1/blocks/latest

# JSON-RPC request
curl -X POST http://127.0.0.1:3333 \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "eth_blockNumber",
    "params": [],
    "id": 1
  }'

# WebSocket subscription
wscat -c ws://127.0.0.1:3333
> {"jsonrpc":"2.0","id":1,"method":"eth_subscribe","params":["newHeads"]}

How It Works

  1. Blockchain Pairing: Consumer queries Lava blockchain for provider pairings
  2. Provider Selection: Selects providers based on stake, QoS, and strategy
  3. Request Routing: Routes user requests to selected providers
  4. Response Validation: Validates responses against finalization consensus
  5. Conflict Detection: Reports any conflicts to the blockchain
  6. QoS Updates: Continuously updates provider QoS scores

Architecture

User Request → RPC Consumer → Blockchain Pairing Query
                     ↓
              Provider Selection (stake-weighted)
                     ↓
              Relay to Providers (parallel)
                     ↓
              Response Validation & Consensus
                     ↓
              Conflict Detection (if needed)
                     ↓
              Return Best Response

vs. RPC Smart Router

Feature RPC Consumer (Decentralized) RPC Smart Router (Centralized)
Provider Discovery On-chain blockchain pairing Static configuration file
Trust Model Trustless (blockchain verified) Trust known providers
Provider Selection Stake-weighted + QoS QoS only
Data Validation Conflict detection + consensus Basic validation
Setup Complexity Medium (requires wallet) Simple (just config file)
Use Case Public networks, trustless Enterprises, known infrastructure
Blockchain Dependency Yes (requires Lava chain) Optional (only for specs)

Monitoring & Metrics

RPC Consumer exposes Prometheus metrics at the configured --metrics-listen-address:

# View metrics
curl http://localhost:7779/metrics

# Key metrics:
# - lava_consumer_relay_requests_total
# - lava_consumer_relay_errors_total
# - lava_consumer_provider_qos_score
# - lava_consumer_cache_hit_rate

Troubleshooting

"No pairings available"
  • Ensure your wallet has an active subscription
  • Check that providers are staked for your requested chain
  • Verify geolocation matches available providers
"Failed to get provider address"
  • Check blockchain connectivity
  • Verify chain-id is correct
  • Ensure subscription is active
Performance Issues
  • Enable caching with --cache-be
  • Adjust --max-concurrent-providers
  • Use --strategy latency for speed
  • Check provider QoS metrics
