Does anyone have a good solution for bugfixing and updating defective smart contracts yet, other than "fork the entire blockchain" Ethereum DAO passim?
If they are to be immutable then you're going to have to code to NASA standards.

This way, if a bug is found, the admin can update the smart contract module guarding the DB table directly vs having to track down the on-chain contracts for migration (if it's even possible). From a normal user's pov, they don't see a difference (unless the admin decides to change the namespace or something).
It's a subtle but important difference. When someone using Pact sends the transaction `(payments.transfer "me" "you" <amt>)` the transaction (after doing a bunch of auth with ppk-sigs) looks up the `payments.transfer` command from the on-chain smart contract and executes it with the provided args. As such, the admin can update buggy contracts without issue (and roll-back, fix tables that have bad data).
