ink-quill

Inspired by Random Oracle, The ink-quill library is a Rust package for efficient and reliable transcript construction. The library provides an efficient way to group various pieces of information, making it easier for verification, storage, or exchange of data.

Usage

[dependencies]
ink-quill = "0.1.0"

TranscriptBuilder

Here's an example of how to create a transcript and add data to it:

use ink_quill::{TranscriptBuilder, TranscriptBuilderInput};

async fn main() {
    let mut builder = TranscriptBuilder::empty("example domain");
    builder = builder.with("nonce", &0)
        .with("transaction", &"deposit")
        .with_prefix("amount".to_string())
        .with("value", &1000_u64)
        compile();
}

TranscriptBuilderInput

For your own data types, you can implement the TranscriptBuilderInput trait:


struct MyData {
    pub value: u64,
}

impl TranscriptBuilderInput for MyData {
    const TYPE: &'static str = "MyData";

    fn to_transcript_builder_input(&self) -> Vec<u8> {
        self.value.to_be_bytes().to_vec()
    }
}
