Here's the weekly update for this week. As the BlockDAG ecosystem continues to showcase its strength, scalability, and potential as a leading blockchain platform. With every milestone achieved, we reinforce our commitment to innovation, transparency, and community growth. 
Let’s take a closer look at the latest key statistics that define our progress:

 

• BlockDAG Price: The current value of BlockDAG stands at $0.0234, marking its position as a promising and accessible asset in the blockchain space. With a foundation built for growth, the potential for value appreciation is immense.
• Total Blocks: With an impressive 553,785 blocks created, the BlockDAG network demonstrates its technical prowess and ability to sustain heavy operational loads. Each block represents a step forward in building a reliable and scalable blockchain ecosystem.
• Last Safe Block: At 553,784, the most recent safe block highlights BlockDAG's robust security and efficient consensus mechanism, ensuring trust and reliability for users and developers alike.
• Total Transactions: Surpassing 730,141 transactions, the BlockDAG network solidifies its position as a high-performing blockchain platform capable of meeting increasing demand with unmatched efficiency.

These metrics are more than just numbers; they represent our commitment to providing a blockchain platform that is secure, scalable, and sustainable. They underscore the network's readiness to handle a wide range of use cases, from decentralized applications to enterprise-level solutions.

We are excited to unveil a new developer release for the BlockDAG project, reflecting our unwavering commitment to innovation and technical excellence. This update introduces critical enhancements designed to empower users and developers within our ecosystem. Below is a comprehensive overview of the key updates:
Contract Verification Feature
Our team has successfully deployed an advanced contract verification feature within the BlockDAG Explorer, enabling users to validate ERC-20, ERC-721, and ERC-1155 contracts seamlessly. Verified contracts grant users access to both read and write functions, ensuring greater transparency, interactivity, and trust.

Bytecode Verification Process:
 

• Extract the bytecode from the deployed contract on the BlockDAG network.
• Compare the extracted bytecode against the source code compiled with specific compiler settings.
• Utilize cryptographic algorithms like SHA-256 to generate a hash for both sets of data.
• If the hashes match, mark the contract as verified. Otherwise, reject the verification request.

Sample Pseudocode:
 def verify_contract(deployed_bytecode, source_code):
    compiled_bytecode = compile_source_code(source_code)
    if hash_function(deployed_bytecode) == hash_function(compiled_bytecode):
        return "Verified"
    return "Verification Failed"
 

1. ABI Decoding Pipeline:
   • Parse the Application Binary Interface (ABI) to extract function signatures and input/output parameters.
   • Employ multi-threaded decoding algorithms to enhance speed and accuracy.
2. Sample Algorithm:
   • Input: ABI JSON file
   • Output: Read/Write interface
   • Steps:
     1. Parse JSON to identify function signatures.
     2. Map functions to readable UI components.
     3. Integrate safety checks for unrecognized functions.
3. Metadata Retrieval and Display:
   • Integrates with decentralized storage (e.g., IPFS) to fetch contract metadata such as compiler version, optimization flags, and license information.
   • Ensures seamless user experience by embedding metadata within the Explorer UI.
4. Security Enhancements:
   • Implements access control mechanisms to ensure only authorized developers can submit verification requests.
   • Employs anomaly detection algorithms to flag suspicious verification attempts.

This feature represents a significant step forward in creating a developer-friendly environment that fosters transparency and collaboration.

The "parent gap" issue in blockchain systems arises when the difficulty adjustment mechanism fails to appropriately regulate block production rates. This document explains the root cause of the issue, the implemented fix, and its impact on system behavior, specifically focusing on dynamic difficulty adjustment and prevention of excessive block production.

Old Logic

In the previous implementation of the RequiredDifficulty function, the difficulty adjustment logic relied on a constant difficulty value under specific conditions. Here is the relevant snippet from the old logic:
if !m.needAjustPowDifficulty(block, powInstance.GetPowType(), needAjustCount) {
    return m.findPrevTestNetDifficulty(block, powInstance), nil
}The function m.findPrevTestNetDifficulty returned a static difficulty value when difficulty adjustment was deemed unnecessary (!m.needAjustPowDifficulty(...) condition true). 

This static difficulty:

• Ignored real-time blockchain conditions.
• Failed to account for the rapid production of blocks.

As a result, excessive block production occurred, leading to a "parent gap" issue where newly mined blocks could not properly reference their immediate predecessors, disrupting the chain's integrity.
 

Updated Logic
To resolve the issue, the logic was updated to return the oldDiff (difficulty of the most recently mined block) instead of the static value from m.findPrevTestNetDifficulty. Here is the updated logic:
if !m.needAjustPowDifficulty(block, powInstance.GetPowType(), needAjustCount) {
    return oldDiff, nil
}

1. Dynamic Adjustment:
   • The returned difficulty now reflects the current state of the blockchain (oldDiff).
   • This allows the system to adapt to real-time block production rates.
2. Elimination of Static Difficulty:
   • By removing reliance on a constant difficulty value, the system avoids artificially accelerating block production.

1. Dynamic Adjustment of Difficulty

• The oldDiff value evolves naturally with the blockchain, ensuring that difficulty aligns with the network's mining activity.
• Prevents long-term discrepancies in block production rates.
   

2. Prevention of Excessive Block Production

• In the old implementation, static difficulty values enabled miners to produce blocks rapidly.
• The new dynamic adjustment mechanism ensures that difficulty scales appropriately, slowing down block production to sustainable rates.
   

3. Resolution of Parent Gap Issue

• By maintaining appropriate block production rates, the new logic ensures that blocks reference their immediate predecessors correctly.
• This fix restores the integrity of the blockchain's structure.

We're excited to introduce a critical update to the difficulty adjustment logic, replacing the static m.findPrevTestNetDifficulty with the dynamic oldDiff. This enhancement ensures real-time difficulty adjustments, prevents excessive block production, and resolves the parent gap issue, strengthening chain continuity and robustness. By safeguarding blockchain integrity and maintaining network stability under varying conditions, this change reinforces scalability and paves the way for a more resilient and future-ready blockchain ecosystem.
