|
||||
* Indices and Identifiers:
|
||||
* The word "index" is used ambiguously throughout this code. It is
|
||||
* particularly confusing when talking about the output or transaction
|
||||
* tables since their indexing can refer to themselves or each other.
|
||||
* I have attempted to clarify these usages here:
|
||||
*
|
||||
* Blocks, transactions, and outputs are all identified by a hash.
|
||||
* For storage efficiency, a 64-bit integer ID is used instead of the hash
|
||||
* inside the DB. Tables exist to map between hash and ID. A block ID is
|
||||
* also referred to as its "height". Transactions and outputs generally are
|
||||
* not referred to by ID outside of this module, but the tx ID is returned
|
||||
* by tx_exists() and used by get_tx_amount_output_indices(). Like their
|
||||
* corresponding hashes, IDs are globally unique.
|
||||
*
|
||||
* The remaining uses of the word "index" refer to local offsets, and are
|
||||
* not globally unique. An "amount output index" N refers to the Nth output
|
||||
* of a specific amount. An "output local index" N refers to the Nth output
|
||||
* of a specific tx.
