In the diagram below we can see block #277316, which contains Alice's transaction. Below it are 277,315 blocks, linked to each other in a chain of blocks (blockchain) all the way back to block #0, the genesis block. Over time, as the "height" in blocks increases, so does the computation difficulty for each block and the chain as a whole. The blocks mined after the one that contains Alice's transaction act as further assurance, as they pile on more computation in a longer and longer chain. The blocks above count as "confirmations". By convention, any block with more than 6 confirmations is considered irrevocable, as it would require an immense amount of computation to invalidate and re-calculate six blocks. We will examine the process of mining and the way it builds trust in more detail in <<mining>>.
