Approach Analysis
Topic: Bitcoin's consensus protocol and its purpose. We'll evaluate each option to see why it may or may not be true. Option 1: 'Bitcoin uses a consensus protocol so that no nodes may be tampered with.' While consensus helps protect the network from inconsistent views, saying no nodes may be tampered with is too strong; nodes can be compromised, but the protocol aims to ensure agreement on a single history even in the presence of faulty nodes. This statement mischaracterize......Login to view full explanation

A 5​1‐percent attacker​ is someone who controls 51 percent or more of the mining power in the Bitcoin network. Let’s say the 51 percent attacker creates an invalid block that contains an invalid transaction that represents stealing bitcoins from an existing address not belonging to the attacker and transferring them to his own address. Can the attacker subvert the consensus process? Which of the following statement(s) is/are true?

In blockchain, the longest-chain criterion is based on the idea that the blockchain data structure that comprises the least number of blocks represents the most aggregated computational effort.

A simplified version of the Bitcoin Consensus Algorithm is shown below: 1. New transactions are broadcast to all nodes 2. Each node collects new transactions into a block 3. In each round a random ​node gets to broadcast its block 4. Other nodes accept the block only if all transactions in it are valid (unspent, valid signatures) 5. Nodes express their acceptance of the block by including its hash in the next block they create Using this algorithm, can a user such as Alice, who really dislikes Bob, deny service to Bob by not including Bob’s transactions in any block that she proposes to get onto the blockchain?
