Use a proposal instead.
Thanks. I've had a look at proposal and seems it's more complex and costs more if I understand correctly. Please correct me if I'm wrong.
Say I have a "multisig" account which is controlled in 2/3 way with active and owners PkA,PkB and PkC. What I want is simply transfer fund from "multisig" account to "someone".
To my understanding,
1. I need a transaction which contains proposal_create_operation. I don't even know who will pay the fee as I have only the multisig account.
2. I need PkA to sign a transaction containing proposal_update_operation to add his/her approval, again I don't know which account to pay the fee.
3. I need PkB to sign a transaction containing proposal_update_operation to add his/her approval, again where can PkB pay the fee.
4. The proposal executes.
As I understand, this will be more complex and fee is about <0.0277 BTS for proposal create + 2*0.00092 BTS for proposal update> where as simple transfer costs about 0.0033 BTS. The proposal way will cost about 10x of simple transfer.
