Snowblossom Improvement Proposal 4

SIP4: Add optional Transaction Input

Change

In this change, we add an optional field to TransactionInput for the value of the input. If it is set (non-zero) transaction validation will ensure that it accurately represents what is happening in the transaction. Validation will fail if it is set (non-zero) and is incorrect.

This change makes it so that an offline transaction signer can have a more complete view of a transaction before signing it. This also enabled the Rosetta API offline /construction/parse .

Code

Work in progress.
