That's basically how hashes and signatures work anyways. They basically take in the result of the previous block and integrate it into the new block so that if you change any part of the previous parts, the whole thing breaks.
Edit: I should specify this is how the algorithms themself work. Implementations can fuck this up (and they do a lot).
- jimktrains2 3y agoThere are also Merkel trees, which are closer to the signature -on-"subdocuments" mentioned above. Also blockchains that explicitly include the previous block's hash.
