Dev Release-207

This development release outlines our latest progress across the BlockDAG ecosystem, spanning Explorer enhancements and EVM blockchain load testing. As we move towards a more robust and developer-centric platform, our focus remains on high performance, real-time data fidelity, and intelligent miner-device interactions.
 

From backend logic that ensures contract-level transaction traceability to load-tested DAG-EVM compatibility and fine-tuned session management in the X10 hardware, this release continues our momentum toward a seamlessly integrated Web3 and mining ecosystem.

To document and communicate recent technical upgrades around DAG-EVM performance, Explorer’s evolving contract and data layer intelligence, and the reinforced reliability of the X10 miner framework. This release sets the foundation for stability under scale, ecosystem transparency, and hardware-software harmony.

• Explorer now supports contract calls with multiple transactions, each now independently traceable.
• DAG-EVM load testing was successfully executed with a focus on UTXO-free stability.
• Miner difficulty tuning underway for consistent 1-second hash rate targets.
• Session management test coverage added for the X10 miner to ensure reliability under real-world usage.
• Faucet module rendering issue resolved, users can now seamlessly request test tokens.

These changes directly impact the performance, usability, and scalability of the BlockDAG platform:

• More Accurate: Explorer can now parse and display every transaction in a contract call flow.
• More Resilient: Load-tested blockchain logic reveals real-world strength under stress.
• Hardware Aligned: X10 session behaviors are now thoroughly test-covered, reducing device-side errors.
• Developer Empowered: Data integrity tracking ensures reliable testnet sync and contract execution.

Multi-Transaction Smart Contract Visibility

Smart contracts with multiple internal transactions will now have each transaction distinctly visible in the Explorer UI. This ensures full traceability of contract behavior and user interactions, enabling developers and auditors to debug complex logic more transparently.

Missing Block Detection & Recovery Logic

A new backend mechanism was introduced to:

• Scan and compare expected block ranges with current DB entries.
• Identify and log missing blocks.
• Queue missing block numbers for recovery attempts.

This mechanism enhances chain completeness and resilience, particularly in distributed or delayed network sync scenarios.

EVM Load Testing

Our blockchain team ran rigorous load tests on the DAG-EVM setup. 
Key goals were:

• Validate EVM compatibility under high transaction throughput.
• Ensure zero UTXO code remains in the current model.
• Identify memory or sync bottlenecks under stress.

Results showed acceptable performance under simulated real-world conditions, marking a strong readiness for public testnet operations.

Miner Difficulty Adjustment: 1-Second Hash Rate

A new dynamic difficulty adjustment mechanism is in development. 
Objective:

• Align the mining device output to one valid hash per second.
• Create predictable block production and optimize reward distribution fairness.
• Stabilize mining pool behavior across X1, X10, and future X30 devices.

This update is vital for ensuring balanced mining across heterogeneous device setups and fostering network consistency.

Test Coverage for Session Management

Comprehensive testing now backs the session management module on X10 devices:

• Unit Tests: Session creation, expiration, heartbeat (ping) handling, and status flag changes.
• Integration Tests: Simulated pings, notification dispatch flows, and reactivation edge cases.

These tests significantly reduce regression risk and elevate hardware-software interaction reliability, critical for scaling miner adoption in varying environments.

• Faucet list rendering now works correctly on the Explorer UI.
• Smart contract visibility improves when multiple internal messages are invoked.

• Advanced Filter (To/From – Include/Exclude) not fully functional; fix in progress.
• TPS (Transactions Per Second), TPB (Transactions Per Block), and Avg Time metrics not loading; backend patch upcoming.

Continue benchmarking DAG-EVM stack under sustained contract execution load.

With this release, BlockDAG is taking another leap toward a modular, hardware-aware, developer-empowered blockchain platform. We’ve laid the groundwork for strengthening the Explorer as a full-stack contract debugger and pushed the mining experience into stable, test-covered territory.

Stay tuned for testnet launches, deeper DAG insights, and an exciting future of scalable decentralized computing!
