As a result, mining is a very competitive business where no individual miner can control what is included in the block chain. Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:. As Finney hypothesized:. Forget mining. Mining creates the equivalent of a competitive lottery that makes it very difficult for anyone to consecutively add new blocks of transactions into the block chain. Could users collude against Bitcoin? However, these features already exist with cash and wire transfer, which are widely used and well-established.

In short, all transactions are hashed and those hashes are paired before being hashed again, and so forth until you reach the parent hash of all transactions, called the Merkle Root. Again, what this basically does is it converts all that data into a string of characters that uniquely identifies that block and its data. As payment for goods or services.
