Rebar Shield v1.1.0: Fee Rate-Based Ordering

---

Rebar Shield v1.1.0 introduces revolutionary fee rate-based transaction ordering, replacing the previous latency-based mechanism. This major architectural change aligns economic incentives with transaction priority, providing developers with predictable and controllable transaction ordering through fee rate optimization.

---

• New Architecture: Transaction position within blocks determined by fee rate rather than latency
• Economic Alignment: Direct correlation between fee payment and transaction priority
• Predictable Outcomes: Developers can guarantee transaction ordering through fee rate optimization
• Fair Market Dynamics: Transparent pricing mechanism for transaction priority

• Expanded Network: Additional mining pools integrated into Rebar Shield network
• Improved Security: Enhanced cryptographic protocols for miner communication
• Performance Optimization: Reduced latency in miner transaction relay
• Private Channels: Secure transaction distribution to participating miners

---

• Support for higher transaction volumes with fee-rate ordering
• Optimized queue management algorithms
• Improved resource allocation for large-scale operations

• More efficient memory usage for transaction queue management
• Reduced computational overhead
• Enhanced database performance

• Real-time fee rate analytics dashboard
• Transaction priority visualization
• Performance optimization suggestions

Include fee rate parameters in all transaction submissions:

// Old approach (deprecated)
submitTransaction(tx);

// New approach (v1.1.0)
submitTransaction(tx, { 
  feeRate: calculateOptimalFeeRate(),
  priority: 'high' 
});

Implement dynamic fee rate calculation based on priority needs:

• High priority: 150+ sats/vByte
• Medium priority: 50-150 sats/vByte
• Low priority: 10-50 sats/vByte

New error responses for fee rate validation:

• FEE_RATE_TOO_LOW: Increase fee rate for desired priority
• INVALID_FEE_RATE: Check fee rate format and value
• PRIORITY_MISMATCH: Adjust fee rate to match priority level

Validate transaction ordering with various fee rate scenarios using our simulation tools.

Important: The latency-based ordering mechanism is deprecated. While there's a 30-day transition period with fallback support, immediate migration is recommended.

• Latency-based transaction ordering
• Legacy submission endpoints without fee rate parameters
• Time-based priority calculations

• New required fee_rate parameter in transaction submission
• Updated response format with fee rate information
• Enhanced error codes for fee-related issues

---
