== Description

Contains all the previous outputs consumed by all transactions in a specific block. Internally it holds a nested vector. The top level vector has an entry for each transaction in a block (in order of the actual transactions of the block and without the coinbase transaction). This is exposed through xref:btck_TransactionSpentOutputs-05.adoc[`btck_TransactionSpentOutputs`]. Each btck_TransactionSpentOutputs is in turn a vector of all the previous outputs of a transaction (in order of their corresponding inputs).
