Questions on: merkle-tree

The idea (as I understand it) is that the Merkle tree allows for you to verify transactions as needed and not include the body of every transaction in the block header, while still providing a way to verify the entire blockchain (and therefore proof
Once a miner has found a block, how easy it is for him to add or remove a tx included in that very block? It is impossible. The solved block depends on every byte of transaction data, nothing can be changed. It is important that it be this way
Edit: Have a look at MSG_MERKLEBLOCK. Included information is: Block Header, Transaction Count, Hash Count, hashes, flag byte count, and flags. hashes include everything from the leaf to root, and flags gives the positions of the leaf in the Merkle t
I think I understand the basic operation of the Bitcoin protocol. Blocks are the "long-term memory" of the network used to prevent double spending (and the way the network agrees in first place). Proof of work is sort of brute-forcing the nonce so th
One compute-intensive part of the server work is creating new merkle roots. As mckoss mentions this becomes a lot faster if you only recalculate the merkle branch that is changed by the new generation transaction instead of recalculating the entire m
No, you can't. The block chain is a linked list of blocks, and each block contains an array of transactions. Block headers commit to a Merkle tree of the transactions in them, but they are sorted chronologically, not by txid, so you need a linear sea
Merkle trees are a fundamental part of what makes blockchains tick. Although it is definitely theoretically possible to make a blockchain without Merkle trees, simply by creating giant block headers that directly contain every transaction, doing so p
An example of a binary hash tree. Hashes 0-0 and 0-1 are the hash values of data blocks 1 and 2, respectively, and hash 0 is the hash of the concatenation of hashes 0-0 and 0-1. In cryptography and computer science, a hash tree or Merkle tree is a tr
