Add authority for simplicity, will modify for multiple validators in the future
Modify Transaction format to include a nonce (will be used for challenges) When an exit gets finalized, the coin's balance value will be written with the exit's balance value
If an operator tries to submit an earlier state the user can challenge by submitting a signed transaction by the operator for some nonce The operator has to respond, otherwise the challenge goes through Finalizing a channel challenge initiates an exit for the coin under the challenge and awards the WHOLE coin to the user, even if the operator previously owned a part of it in the off-chain state This is experimental and the technique may be subject to change

Implementing Plasma Debit. Very experimental, still no spec for conciseness.
Currently supports partial withdrawals where a user will get
aand the operatorv-a.If the operator cheats and submits an earlier nonce they can get challenged and forfeit the whole coin in a similar fashion to how the whole value inside a payment channel goes to the challenger if they win the dispute. Response still not impemented but will require the op to prove that a tx with a higher nonce was either signed by the user or was the one included in the block in question (probably?)
Also supports liquidity injections by the operator in a coin
