Breakdown of a Ravencoin Asset Transfer Transaction

This document presents the raw transaction for an asset transfer on the Ravencoin testnet blockchain, and decodes the purpose of every byte in the transaction.

Note that asset operations are always encoded as extra information appended to the scriptPubKey of outputs having a value=0

For details about the Ravencoin asset operation encoding method, please see HERE

Transaction Structure:

2 inputs:

0) the source of RVN for the transaction fees
1) the source of the asset tokens

3 output:

0) the target for the asset tokens
1) change for the remaining RVN
2) the change back for the remaining assets

Note that asset operations are always encoded as extra information appended to the scriptPubKey of outputs having a value=0
