This sounds like Core War [1] meets blockchain.

Indeed it is, thank you for the link!

This seems similar to 857Coin https://github.com/davidlazar/6.857coin

It looks like they are not too much similarities, except that they are both took some structure from the Bitcoin. Hackchain is less about signatures, public keys, mining the blocks; and is more about the output/input scripts in the transactions.
