hash locked multisig, can one cosigner sign without the pre-image?

hash locked multisig, can one cosigner sign without the pre-image?

Consider Alice and Bob created the following native segwit script:

hash SHA256 defined as H | Alice PubKey | Bob Pubkey

Only Bob has the pre-image (plain text that hashes [sha256] to H). Can Alice just sign a transaction without revealing H, and just hand over the partially signed transaction off chain to Bob so he can reveal H + add his signature, make the transaction final and spend it?

The catch here is that neither Alice and Bob to be in total and exclusive control of the funds, but for Bob to have to reveal an additional secret as spending condition.

On Coinbase Pro does anybody know what criteria are used to decide if a limit order should be rejected due to insufficient funds?

On Coinbase Pro does anybody know what criteria are used to decide if a limit order should be rejected due to insufficient funds? I'm playing around with their sandbox api and trying to figure out when a buy order will be rejected due to insufficient funds. It seems that market orders will be rejected only if you give the order funds greater than the amount of USD you have in your wallet. That seems straight forward enough. The case for limit orders seems a little bit more complicated. If I have $1000 in my wallet and I specify a buy order for 1 BTC for $1000 the order will be rejected due to insufficient funds. I'm guessing this is because I need money for any possible fees. However if the order goes on the order book as a maker order. My question is do I need enough USD for possible fees regardless if the order becomes a maker or a taker order? http://bit.ly/2EHpQ7R
