L2 Block Format Specification

Abstract

This LP defines a standardized block format specification for L2 rollups on Lux Network, optimizing for compression, efficient state transitions, and specialized metadata for AI computations. The format supports multiple transaction types including standard transfers, smart contract calls, AI inference requests, and distributed training updates. It implements advanced compression techniques achieving 10-20x reduction in data size, batch aggregation for efficient L1 settlement, and cryptographic commitments for state integrity. The specification includes extensions for cross-rollup communication and quantum-resistant signatures.

Activation

Parameter	Value
Flag string	lp505-l2-block-format
Default in code	false until block X
Deployment branch	v0.0.0-lp505
Roll‑out criteria	1M blocks produced
Back‑off plan	Legacy format support

Motivation

Current L2 block formats lack:

1. Compression Optimization: Inefficient data encoding
2. AI Metadata: No support for compute workload tracking
3. Batch Efficiency: Poor aggregation for L1 submission
4. Cross-rollup Standards: Incompatible formats between L2s
5. Future-proofing: No quantum-resistant signature support

This specification provides:

• 90% Size Reduction: Advanced compression techniques
• AI-Native Support: Built-in compute metadata fields
• Efficient Aggregation: Optimized for batch submission
• Interoperability: Standard format across rollups
• Quantum Resistance: Support for post-quantum signatures

Rationale

Block Structure Design

The nested structure provides:

• Modularity: Separate concerns (header, transactions, state)
• Efficiency: Optimal field ordering for compression
• Extensibility: Metadata fields for future additions
• Compatibility: Support for existing Ethereum transactions

Compression Strategy

Multi-level compression approach:

1. Field Extraction: Common fields stored once
2. Delta Encoding: Only store differences
3. Dictionary Compression: Shared dictionaries for common patterns
4. Algorithm Selection: Choose optimal per data type

Expected compression ratios:

• Standard transfers: 15-20x
• Smart contract calls: 8-12x
• AI metadata: 5-8x
• State deltas: 10-15x

AI Metadata Inclusion

Following emerging standards for AI workload tracking:

• Resource Accounting: Precise compute usage tracking
• Performance Metrics: Latency and throughput monitoring
• Model Versioning: Checkpoint and version tracking
• Verification: Proofs of correct computation

Quantum Resistance

Preparing for post-quantum era:

• Hybrid Approach: Classical + quantum signatures
• Algorithm Agility: Support multiple PQ algorithms
• Graceful Migration: Upgrade path for existing accounts
• NIST Standards: Following standardized algorithms

Backwards Compatibility

The format maintains compatibility through:

1. Version Field: Indicates format version
2. Legacy Support: Can encode as standard Ethereum blocks
3. Progressive Enhancement: New fields are optional
4. Migration Tools: Converters between formats

Security Considerations

Data Integrity

1. Hash Verification: Every component has merkle proofs
2. Signature Validation: Multiple signature schemes supported
3. Compression Safety: Decompression bombs prevented
4. Canonical Encoding: Prevents malleability attacks

Compression Security

1. Size Limits: Maximum decompressed size enforced
2. Dictionary Validation: Shared dictionaries verified
3. Algorithm Safety: Only approved algorithms
4. DoS Prevention: Complexity limits on decompression

Quantum Security

1. Algorithm Selection: NIST-approved algorithms only
2. Key Sizes: Minimum 256-bit security level
3. Hybrid Mode: Classical + quantum for transition
4. Side Channels: Constant-time implementations

Cross-Rollup Security

1. Message Authentication: Signatures required
2. Replay Protection: Nonces and chain IDs
3. Inclusion Proofs: Merkle proofs of message
4. Timeout Handling: Messages expire after deadline

Economic Impact

Storage Cost Reduction

Data Type	Original Size	Compressed	Savings
Transfers	200 bytes	10 bytes	95%
Contract Calls	500 bytes	50 bytes	90%
State Updates	1 KB	100 bytes	90%
AI Metadata	2 KB	400 bytes	80%

L1 Settlement Costs

• Before: $10 per 100 transactions
• After: $0.50 per 100 transactions
• Annual Savings: $10M+ at 100K tx/day

Performance Improvements

• Block Production: 10x faster
• State Sync: 5x faster
• Light Client Verification: 20x faster

Open Questions

1. Optimal Compression Dictionary: Size vs efficiency tradeoff
2. Quantum Migration Timeline: When to enforce PQ signatures
3. Cross-Rollup Standards: Industry-wide standardization
4. Compression Algorithm Updates: Upgrade mechanism
