LRP protocol

Overview

LRP protocol allows buyer and seller to make a p2p payment while the cryptocurrencies of the buyer have locked until the seller delivers the order. The below diagram will explain the logic of LRP protocol when the sellers integrate with Libra Network.

Payment state transition

Data structure of payment

Payment<T: Config> {
  pub id: u128,
  pub payer: AccountOf<T>,
  pub payee: AccountOf<T>,
  pub amount: BalanceOf<T>,
  pub currency_id: CurrencyIdOf<T>,
  pub description: Vec<u8>,
  pub status: PaymentStatus,
  pub receipt_hash: <Runtime as system::Config>::Hash,
  pub created_at: MomentOf<T>,
  pub updated_at: MomentOf<T>,
  pub updated_by: AccountOf<T>,
}
