I'm interested to hear people's opinions on this.

What are the advantages of using a blockchain over a block lattice? Neither has been "hacked", at least at this point, and the block lattice seems to just be way faster (at least with my experience using Nano), and there aren't any confirmations etc so you can use the funds immediately.

Is there any reason to continue using blockchains in the future rather than try to build new coins on a Lattice architecture?
