Welcome to BlockDAG Dashboard! 👋


Dev Release 34

May 20, 2024

Greetings BlockDAG Community,


Today, our development team focused on enhancing the offchain work for miners in our BlockDAG architecture. By leveraging offchain computation, miners can perform complex tasks more efficiently, reducing the load on the blockchain and speeding up the mining process. Here’s a detailed look at what we accomplished today, including key algorithms and mathematical formulas, and the immediate benefits this brings to our ecosystem.

Today's Focus: Offchain Computation for Miners

Offchain computation allows miners to execute resource-intensive operations outside the main blockchain network, ensuring that only the essential results are recorded onchain. This approach enhances overall performance and reduces network congestion.


Key Achievements Today


Optimized Mining Algorithms:
We developed and implemented optimized mining algorithms that can be executed offchain. These algorithms allow miners to solve cryptographic puzzles more efficiently.

Steps Taken:

  • Designed new mining algorithms that split computational tasks between onchain and offchain processes.
  • Implemented offchain modules to handle the heavy lifting of hash computations.
  • Developed protocols to securely transfer computed results back to the blockchain.


Algorithm for Offchain Mining Computation:

function offchainMine(blockData, targetDifficulty): 

     while true: 

nonce = generateRandomNonce() 

partialHash = offchainSHA3(blockData, nonce) 

        if meetsDifficulty(partialHash, targetDifficulty): 

           return partialHash, nonce 




  • Secure Offchain Result Verification:

Ensuring the integrity and authenticity of the offchain computed results is crucial. We designed protocols for secure result verification.

Implementation Details:

  • Established secure channels for transmitting offchain computation results to the blockchain.
  • Used cryptographic techniques to ensure the integrity of the offchain results during transmission.
  • Implemented onchain smart contracts to verify the validity of the results submitted by miners.


Mathematical Formula for Result Verification:
Given a dataset D, nonce n, and target difficulty T, the verification formula is:
Where H is the hash function (e.g., SHA-3). The miner’s goal is to find a nonce n such that the hash of the block data and nonce is less than the target difficulty.

  • Distributed Offchain Mining:

We explored and implemented a distributed offchain mining approach where multiple miners collaborate on solving the same cryptographic puzzle.

Progress Made:

  • Set up a network of miners to share computational tasks.
  • Developed protocols for distributing workload and aggregating results.
  • Implemented consensus mechanisms to validate collaboratively obtained solutions.


  • Mathematical Formula for Distributed Mining:

Let M be the number of miners and Wi the work done by miner i. The total work W is distributed as:
The goal is to minimize the time T to find a valid nonce, achieved by parallelizing the computation:
Where Tsingle is the time taken by a single miner to find a valid nonce.


Immediate Benefits

  • Enhanced Mining Efficiency:
    Offloading complex computations to offchain environments reduces the time required for miners to solve cryptographic puzzles, enhancing mining efficiency.
  • Reduced Blockchain Congestion:

By performing heavy computations offchain, the overall load on the blockchain network is reduced, leading to lower congestion and faster transaction processing.

  • Improved Scalability:

Offchain computation allows for handling a higher volume of mining operations without compromising the performance of the blockchain, resulting in improved scalability.

  • Cost Efficiency:

Offloading computations reduces the onchain processing costs, making the mining process more cost-effective for miners.
Applications and Use Cases
Today's advancements in offchain computation for miners unlock new possibilities for various applications:

  • Mining Pools: Miners can form offchain pools to collaboratively solve cryptographic puzzles, enhancing the chances of successfully mining new blocks.
  • Decentralized Applications (dApps): Offchain computation can be used to handle intensive computational tasks required by dApps, improving their performance and user experience.
  • Blockchain-Based Research: Offchain computation allows researchers to perform complex simulations and analyses without overloading the blockchain network.


Today’s progress in integrating offchain computation for miners marks a significant step forward in enhancing our BlockDAG system's capabilities. By offloading resource-intensive tasks from the main blockchain, we can achieve greater efficiency, scalability, and cost-effectiveness, paving the way for more advanced and innovative applications.
