Chapter 5: Bitcoin Mining This chapter is all about mining. We’ve already seen quite a bit about miners and how Bitcoin relies on them — they validate every transaction, they build and store all the blocks, and they reach a consensus on which blocks to include in the block chain. We also have already seen […]
