Block context in LEE: a design exploration

[sergei-tikhomirov]

Added an exploration on time-related primitives as used in uni-directional and bi-directional payment channels as well as payment streams, with implications for LEE-based implementations of off-chain payment protocols:

Off-Chain Payment Protocols on LEE

This post is a follow-up on Block context in LEE: a design exploration. This document identifies requirements for time-information exposure in LEE programs to support off-chain payment protocol implementations. Off-chain protocols need timelocks to enforce temporal ordering of on-chain settlement actions. Without timelocks, depositors cannot guarantee refund access if a counterparty disappears, and honest parties cannot be given time to respond to fraudulent settlement attempts. The specific …
