Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

sha256d is the answer.
To save others time searching for what sha256d is, it is just sha256 done twice, so "d" probably stands for "double".

Bitcoin PoW algorithm is double sha256, just like it uses double sha256 for computing transaction hashes.
