On average, the miners create a new blockchain every 10 minutes, containing information of all prior transactions and a new transaction block. Every two weeks, Bitcoin’s source code is made for the adjustment of the amount of Bitcoin mining power required for the creation of new blockchains, which is required to provide the average creation interval of 10 minutes. If mining power gets enhanced during these two weeks, then it becomes difficult to form new blockchains for the subsequent two-week span. On the other hand, if mining power declines, it is easier to form new chains. However, for most of Bitcoin’s history, there is a demand for greater mining power.

Each computer in the blockchain network makes its own copy of the blockchain, which reflects that there could be thousands of it, and in the case of Bitcoin, there could be millions of copies of the same blockchain. Each copy of the blockchain is exactly identical, that makes the distribution of that information across a network of computers more difficult to manipulate. In order to manipulate a single block, a hacker requires to change every single block after it on the blockchain, which leads lots of recalculations.
