As someone mentioned earlier, the LEAT asset on counterparty seems to have something to do with this puzzle. Seems to be spelled LEAT instead of LEET because https://counterpartychain.io/asset/LEET is already taken, but possibly also because 347 (EAT in LEET) seems to be an important number to the puzzle creator.

Anyway, there are a total of 347 LEAT created (https://counterpartychain.io/address/1MArwmcosCBy18fMob8wgCbLWiqGuD2nqs). 346 of them are owned by our very own 1FLAMEN6rq2BqMnkUmsJBqCGWdwgVKcegd, and the other 1 LEAT is owned by 15fx1Gqe4KodZvyzN6VUSkEmhCssrM1yD7. Maybe we need to get them combined somehow into the full 347 LEAT to make something happen?

It's also interesting that the 1 LEAT given to 15fx1... was given in block # 343373. I doubt that's a coincidence.
