I have a question about the block part, if i take a 100MB video and add it into IPFS, then a person take that video and cut the file in half and add the file again, will duplicate the 50% of the blocks or will share the blocks ?
(first posted on the wrong place https://github.com/ipfs/go-ipfs/issues/2575)
so my new question is there any chance to save space and dont duplicate blocks even if is 1%
