Expand description

Interpreter’s context (blockchain state)

Fields

height: u32

Current height

self_box: Rc<ErgoBox>

Box that contains the script we’re evaluating (from spending transaction inputs)

outputs: Vec<Rc<ErgoBox>>

Spending transaction outputs

data_inputs: Option<TxIoVec<Rc<ErgoBox>>>

Spending transaction data inputs

inputs: TxIoVec<Rc<ErgoBox>>

Spending transaction inputs

pre_header: PreHeader

Pre header of current block

headers: [Header; 10]

Fixed number of last block headers in descending order (first header is the newest one)

extension: ContextExtension

prover-defined key-value pairs, that may be used inside a script
