The Challenge of Large Blocks in BCH
As a leading example of big-block blockchain technology, Bitcoin Cash (BCH) faces unique challenges in block propagation efficiency. Larger blocks demand more robust hardware from full-node operators (primarily mining farms) and complicate home computer setups for average users. This makes optimizing block propagation speed a top priority for the BCH community.
Past Innovations in Block Propagation
Developers have pioneered several solutions to address these challenges:
- Compact Blocks: Minimizes redundant data transmission
- Xthin Blocks: Ultra-thin block compression technology
- Graphene: BU team's advanced compression protocol
- Xthinner: Jonathan Toomim's CTOR-powered solution achieving 99.54% compression in optimal cases (April 2023 tests)
Introducing BDN: A Game-Changing Solution
Chicago-based bloXroute Labs recently unveiled breakthrough test results with BCH miners:
| Propagation Method | Time for 32MB Block | Speed Improvement |
|---|---|---|
| Standard | 193 seconds | Baseline |
| BDN Network | 2-18 seconds | 10-96x faster |
How BDN Works
- Network Architecture: Decentralized relay nodes forming a global distribution mesh
- Performance Metrics: Processes up to 1,000 TPS (per company CEO Eyal Markovich)
- Efficiency Gains: Reduces Beijing node processing time from 17,151s → 37s
Real-World Testing
- Duration: 2 months on BCH testnet
- Participants: Major mining pools including BTC.com, F2Pool, Rawpool
- Future Plans: ETH network tests followed by BTC/BCH mainnet deployment
Triple Benefits for BCH Ecosystem
- Bandwidth Reduction: Smaller data footprint per transaction
- Fork Recovery: Accelerated reconciliation of missed transactions
- Economic Advantage: Maintains low fees despite 32MB block capacity

FAQs About BDN Implementation
Q: Will BDN require changes to existing BCH nodes?
A: No – it operates as an optional overlay network compatible with current implementations.
Q: How does BDN compare to Xthinner?
A: While Xthinner optimizes single-block compression, BDN enhances network-wide propagation efficiency.
Q: When will BCH miners see tangible benefits?
A: Significant improvements are expected post-mainnet launch, currently projected for Q4 2024.
