So for a merkle tree with 1 million transactions, you'll need about 20 iterations of the loop, maybe 300 cycles. That's about the cost of a 2-3 memory accesses. I can't imagine a scenario where it would be worth optimizing this function or using a heuristic. If you plan on allocating the memory for that merkle tree, you'll spend several orders of magnitude longer doing that. How can I calculate the merkle root of a hyperledger fabric? I have a hard time finding merkle root in Fabric. The block header contains number , prefix_hash , data_hash . Are any of the above three related data related to the merkle root? Or can I calculate a merkle root manually? I have hashed the data I used when I submitted the data to the ... The Bitcoin wiki Vocabulary article explains why the Merkle root exists:. Every transaction has a hash associated with it. In a block, all of the transaction hashes in the block are themselves hashed (sometimes several times -- the exact process is complex), and the result is the Merkle root. Final step is to combine hashes of pairs and calculate hash of them, so-called Merkle root. This is the fingerprint of your 4 files. Bitcoin uses Merkle trees to verify which transactions and in which order are included in any given block. When you send Bitcoin transaction it lands in a set of unconfirmed transactions distributed over thousands of computers called mempool. Then each miner ... I'd like to calculate a Merkle tree on chain, and then only store the root. The tree will track all balances for an ERC20 token. How many accounts would this be feasible for? If there are 1000 ba...
