After in control, the entity is probably not capable to change earlier blocks around the chain, however it can change potential blocks. As an illustration, it may be able to reduce or reverse transactions, potentially even double-paying any copyright pending a slot during the block.
The Bitcoin blockchain collects transaction information and enters it into a 4MB file known as a block (distinct blockchains have distinct measurement blocks).
Think about you typed some info right into a doc in your Laptop or computer and sent it by way of a program that gave you a string of quantities and letters (referred to as hashing, Together with the string known as a hash).
