Proposals are messages sent from Daemon to Client providing data Client needs to proceed in the protocol execution. They propose transactions, presents counterparty signatures and adaptor signatures to Client. With these data, Client is able to create valid, fully signed transactions.

### The `cosign_arbitrating_cancel` Proposal
**Send by**: Alice|Bob daemon
- data:
- [`u16`: `cancel_tx_len`]
- [`cancel_tx_len * byte`:`cancel (d)`] The `cancel (d)` transaction

### The `sign_adaptor_buy` Proposal
**Send by**: Bob daemon
- data:
- [`buy (c)`] buy transaction

### The `fully_sign_buy` Proposal
**Send by**: Alice daemon
- data:
- [`u16`: `buy_adaptor_sig_len`]
- [`buy_adaptor_sig_len * byte`: `buy_adaptor_sig`] The `Bb(Ta)` `buy (c)` adaptor signature

### The `sign_adaptor_refund` Proposal
**Send by**: Alice daemon
data:
- [`u16`: `refund_tx_len`]
- [`refund_tx_len * byte`:`refund (e)`] The refund transaction

### The `fully_sign_refund` Proposal
**Send by**: Bob daemon
- data:
- [`u16`: `refund_tx_len`]
- [`refund_tx_len * byte`:`refund (e)`] The `refund (e)` transaction
- [`u16`: `refund_adaptor_sig_len`]
- [`refund_adaptor_sig_len * byte`: `refund_adaptor_sig`] The `Ar(Tb)` `refund (e)` adaptor signature

### The `sign_arbitrating_lock` Proposal
**Send by**: Bob daemon
- data:
- [`u16`: `lock_tx_len`]
- [`lock_tx_len * byte`:`lock (b)`] The `lock` transaction

### The `sign_arbitrating_punish` Proposal
