Da2ce7:New Transaction

New Transaction is an proposal for a new extendable method of creating transactions.
Each new transaction is defined by a random txnumber that should be unique globally.
Advanced functions, such as transaction scripts, and importing and exporting can appropriately be done using the group of supporting functions.

Transaction life-cycle

Every New Transaction goes through the following steps. (not always in the same order)

Build

In this stage, a transaction is being built:

• Any feature of the transaction may be modified.
• Users can add, remove, any input, output or script.

Ready

In this stage, only certain features may be modified:

• Only inputs may be changed. (is this correct, or will past signatures be destroyed if we change them?)
• Any other attribute that doesn't effect the existing signatures.

Done

In this stage, the transaction is complete, and would be accepted by the network:

• User still can add inputs, however all the outputs have already been fulfilled, these new inputs will be counted as fees.
• After any change, a 'done' transaction gets automatically demoted to 'Ready' state.

Submitted

In this stage the transaction has been published to the bitcoin network and is in/or is awaiting to be included in a block.

Terms

txnumber is a random string given to every transaction for identification purposes.
pubkey is assumed to be owned by the client that preforms the 'readying' of the transition (build > ready states)

This entire processing is lazy! Bitcoin will automatically fill-out everything just as it dose at-the-moment with the readytransaction stage.

Please not this draft doesn't include all possible error responses.
