Blockchain p2p networking

[Steake]

This pull request sets up the foundational project structure and developer workflow for BitCell. It introduces a Rust workspace with multiple crates, comprehensive CI/CD pipelines, benchmarking, and a detailed, user-friendly README.md to guide contributors and users. The changes focus on enabling collaborative development, enforcing code quality, and providing clear documentation.

Project Structure and Workspace Setup:

• Added a Rust workspace in Cargo.toml that organizes the project into modular crates for cryptography, consensus, CA engine, ZK circuits, networking, economics, and more, with shared dependencies and unified profiles.

Continuous Integration and Quality Assurance:

• Introduced a multi-platform CI pipeline in .github/workflows/ci.yml that runs tests, formatting checks, linting, builds, security audits, and code coverage across Ubuntu, macOS, and Windows, ensuring code quality and reliability.
• Added a benchmarking workflow in .github/workflows/benchmarks.yml to automate performance measurement and store results for future comparison.

Documentation and Onboarding:

• Replaced the minimal README.md with a comprehensive, visually appealing guide that explains the protocol, architecture, quick start instructions, tournament mechanics, trust system, ZK circuits, economics, project structure, development workflow, roadmap, FAQ, and credits, making it much easier for new contributors to understand and participate.
• Added a legacy README.old.md for reference to the original project description.

The claim of completing 18-24 person-months of work 'in a focused development session' is vague and potentially misleading. Consider specifying the actual time period (e.g., '2 weeks', '1 month') to provide concrete context for readers.

Suggested change

	From an initial 400+ TODO items representing 18-24 person-months of work, we've successfully implemented the vast majority of critical and important features in a focused development session.

Test count inconsistency: this document claims 39 tests for bitcell-crypto, but line 316 states 'bitcell-crypto: 39 tests (includes ECVRF, CLSAG)' while SUMMARY.md line 37 shows 27 tests. Ensure consistency across all documentation.

Suggested change

	**Tests**: 39 passing
	**Tests**: 27 passing

[Copilot]

Test count discrepancy: This shows 148 tests but FINAL_REPORT.md line 17 claims '157+ tests passing'. Documentation should be consistent about the actual test count.

Suggested change

	**Total Tests**: 148 passing
	**Total Tests**: 157+ passing

Version number inconsistency: SUMMARY.md header states 'BitCell v0.1 Implementation' while this document claims v0.3. Clarify whether these represent different milestones or correct the version numbering.

[Copilot]

Timeline inconsistency: The document states November 2025 as current but sets December 2025 target (1 month), while line 192 estimates '36 days (5-6 weeks)'. Align the timeline estimates.

Suggested change

	**Target Completion**: End of December 2025
	**Target Completion**: Mid-January 2026

[nitpick] Variable naming is inconsistent: using 'b' for the second operand while 'a' is used for the first, but some arithmetic operations also use pattern matching. Consider consistent naming like 'operand1' and 'operand2' or 'lhs' and 'rhs' for clarity.

The production values (1024, 1000) mentioned in comments differ significantly from test values (64, 10). Add documentation explaining when to use test vs production configurations and the implications of these parameter choices.

The prune_old_blocks implementation is incomplete and appears to be a placeholder. Either implement the full pruning logic or clearly document this as a TODO with expected behavior.

Suggested change

	// Verify blocks column family exists
	self.db.cf_handle(CF_BLOCKS)
	.ok_or_else(|| "Blocks column family not found".to_string())?;
	// This is a simplified version - in production would iterate and delete
	for height in 0..prune_until {
	if let Some(header_data) = self.get_header_by_height(height)? {
	// Extract hash and delete block
	// (Simplified - would need proper header deserialization)
	let _ = header_data;
	}
	// Get column family handles
	let cf_blocks = self.db.cf_handle(CF_BLOCKS)
	.ok_or_else(|| "Blocks column family not found".to_string())?;
	let cf_headers = self.db.cf_handle(CF_HEADERS)
	.ok_or_else(|| "Headers column family not found".to_string())?;
	// Iterate and delete blocks and headers for heights less than prune_until
	for height in 0..prune_until {
	// Delete block by height
	self.db.delete_cf(cf_blocks, height.to_be_bytes())
	.map_err(|e| format!("Failed to delete block at height {}: {}", height, e))?;
	// Delete header by height

The comment on line 12 mentions 'TODO: make this 10 minutes in production' but uses 10 seconds. Consider using a configuration parameter instead of a hardcoded constant to avoid accidental production deployment with test values.

Suggested change

	/// Block production interval (10 seconds for testing, TODO: make this 10 minutes in production)
	const BLOCK_TIME_SECS: u64 = 10;
	/// Block production interval (configured via NodeConfig; set appropriately for testing or production)
	// Block time is now configurable via NodeConfig.block_time_secs

[Copilot]

The 10MB message size limit is hardcoded in multiple places (lines 380 and 401). Extract this to a named constant to ensure consistency and ease of configuration.
