Table of Contents
Install
To install libyobicash add in your Cargo.toml:
# Cargo.toml
[dependencies]
libyobicash = "^0.1"
and in the root of your crate:
//main.rs
extern crate libyobicash;
Usage
Look at the documentation or at the tests for guidance.
// main.rs
// Bob wants to send some data to Alice through Yobicash and has found
// a node offering a good price for broadcasting the data.
// let plain = some super important secret.
// let alice_pk = Alice public key;
let bob_sk = SecretKey::random();
let bob_data = Data::new(bob_sk, alice_pk, &plain)?;
// let bob_coins = some spendable coins Bob owns that pay the fee
// required by the node;
// let bob = the output to the node that will broadcast Bob writes operation;
// One secret instance from Bob. Bob will use it to permit the network to
// delete his data.
let bob_instance = Scalar::random();
// The write operation containing the encrypted data that only
// Bob and Alice can read. After confirmation, it will be broadcasted
// to the network.
let bob_write = WriteOp::new(&bob_coins, &bob_data, bob_instance, &bob_fee)?;
println!(write_op.to_json()?);
// Now that the secret is not needed anymore, Bob and Alice agree that it
// can be erased from the dagchain. Bob finds a node with making a good offer
// to get rid of that data and broadcast the operation to the network.
// let node_coins = some spendable coins the node owns that pay Bob's fee;
// let node_fee = the fee promised to Bob by the node;
// Bob generates the proof of the bob_write witness instance to send to the node
// using the fee that the node will use and bob_write itself.
let bob_proof = DeleteOp::proof(&bob_write, &bob_instance, &node_fee)?;
// The node creates a delete operation with Bob's witness.
// The node will delete bob_writes' Data after node_delete get confirmed.
// The other nodes of the network will do the same.
let node_delete = DeleteOp::new(&node_coins, &bob_write, &bob_proof, &node_fee)?;
println!(node_delete.to_json()?);
