You want to fight cancer with even more potent strain (of the same). If you don't cure greed, you won't have trust. And you simply cannot replace human trust with (reverse) surveillance and allegedly "incorruptible records." (Btw. AFAIK blockchains are hackable -- GIYF.) In any case, what you propose is Sumer on steroids, the "ultimate Babylon." You may manage to postpone the inevitable, but that will be it; only, the fallout will be multiplied.
