Bitcoin Esplora Complete Substream

A Bitcoin blockchain data processor that extracts and processes Bitcoin block data, implementing core functionality inspired by the Esplora API.

🚀 What It Actually Does

This Substream processes Bitcoin blocks and extracts:

✅ Currently Implemented:

• Block Information: Hash, height, timestamp, version, difficulty, merkle root
• Transaction Data: TXID, version, locktime, size, weight, fee calculations
• Address Extraction: P2PKH, P2SH, P2WPKH address parsing from script pubkeys
• Network Statistics: Fee calculations, block metrics, transaction counts
• Webhook Events: Block and transaction event generation

🔄 Data Processing:

• Processes Bitcoin block headers and transactions
• Extracts addresses from transaction outputs
• Calculates transaction fees and block statistics
• Generates structured data for all major Bitcoin data types

📊 Data Structures

The Substream processes Bitcoin data into comprehensive structures:

• BlockInfo: Complete block metadata
• TransactionInfo: Full transaction details with inputs/outputs
• AddressInfo: Address statistics and UTXO information
• NetworkStats: Network-level metrics and statistics
• WebhookEvent: Real-time event notifications

🛠️ Technical Implementation

Current Status:

• ✅ Compiles successfully with Rust/WASM
• ✅ Packages correctly as .spkg file
• ✅ Processes real Bitcoin data from blockchain
• ✅ Ready for authentication with JWT tokens
• ✅ All data models defined for Esplora API compatibility

Architecture:

• Input: Bitcoin blocks via sf.bitcoin.v1.Block
• Processing: Rust-based Bitcoin data extraction
• Output: Structured data compatible with Esplora API format
• Storage: Ready for FoundationalStore integration

🚀 Usage

Building:

cargo build --release --target wasm32-unknown-unknown
substreams pack

Running:

# With authentication token
export SUBSTREAMS_API_TOKEN="your_jwt_token_here"
substreams run . map_esplora_complete_data --start-block 800000 --stop-block 800001

Package Information:

• Name: bitcoin-esplora-complete
• Version: v0.1.1
• Network: bitcoin
• Repository: https://github.com/PaulieB14/Bitcoin-Explorer-Substream

📋 What's Working vs. What's Planned

✅ Currently Working:

• Real Bitcoin block processing
• Transaction data extraction from actual blocks
• Address parsing and classification
• Fee and network statistics calculation
• Complete data structure definitions
• Compilation and packaging

🔄 Next Steps (Future Development):

• FoundationalStore data persistence
• Full protobuf output implementation
• Advanced address clustering
• Mempool analysis
• Liquid/Elements support

🎯 Use Cases

This Substream is ideal for:

• Bitcoin Analytics: Block and transaction analysis
• Address Monitoring: Track Bitcoin address activity
• Network Statistics: Real-time Bitcoin network metrics
• Data Indexing: Build Bitcoin data indexes
• API Development: Create Bitcoin data APIs

🔧 Development

Dependencies:

• substreams = "0.0.21"
• prost = "0.11.9"
• hex = "0.4.3"
• sha2 = "0.10.8"
