Tx is the core operation that can be performed. The tx uses the UTXO model. Specifically, a txs inputs will consume previous txs outputs. A tx will be valid if the inputs have the authority to consume the outputs they are attempting to consume and the inputs consume sufficient state to produce the outputs.
