I wrote the algorithm to solve it but it's taking forever. Is the following approach correct? I'm able to get result when I set difficulty to 1,2,3 but anything above it is taking a long time to compute. #JavaScript block{..} function calculateHash(block){ return sha1(block.blockNumber+block.parentHash+block.difficulty+block.resumeHash+block.position+block.name+block.minedBy+block.nonce); } function mineBlock(block,difficulty) { while (calculateHash(block).substring(0, difficulty) !== Array(difficulty + 1).join("0")) { block.nonce++; console.log(block.nonce) } console.log("BLOCK MINED: " + this.hash); } mineBlock(block,<custom_difficulty_level>) // try with 1,2,3 ..it works. console.log(calculateHash(block))
