## Overview
The official standard library for the [Aiken](https://aiken-lang.org) Cardano
smart-contract language.
It extends the language builtins with useful data-types, functions, constants
and aliases that make using Aiken a bliss.
```aiken
use aiken/collection/list
use aiken/crypto.{VerificationKeyHash}
use cardano/transaction.{OutputReference, Transaction}
pub type Datum {
owner: VerificationKeyHash,
}
pub type Redeemer {
msg: ByteArray,
}
/// A simple validator which replicates a basic public/private signature lock.
///
/// - The key (hash) is set as datum when the funds are sent to the script address.
/// - The spender is expected to provide a signature, and the string 'Hello, World!' as message
/// - The signature is implicitly verified by the ledger, and included as 'extra_signatories'
///
validator hello_world {
spend(datum: Option, redeemer: Redeemer, _, self: Transaction) {
expect Some(Datum { owner }) = datum
let must_say_hello = redeemer.msg == "Hello, World!"
let must_be_signed = list.has(self.extra_signatories, owner)
and {
must_say_hello,
must_be_signed,
}
}
}
```
