Blazing the Trails: Improving LND Pathfinding Reliability 🛤️

Bitromortac
May 23, 2024

In Part 1 of the pathfinding blog post series we saw that with empirical engineering one can already design a reasonable and transparent probability estimator essential for improving payment success. However, it has limitations regarding predictability and is not very flexible. Thus, we introduced an alternative estimator that employs a more rigorous mathematical approach to estimate probabilities. This method, formalized in a seminal publication is based on an assumed liquidity distribution…

A Technical Walkthrough of Hash Time Locked Contracts and Lightning Channel Operations

Elle Mouton
June 28, 2023

This post will walk through the different operations of a Lightning channel by following a long-running example with plenty of explanatory diagrams. First, we explore how Hash Time Locked Contracts (HTLCs) are added to a channel and how channel peers commit to a new state including these HTLCs. Next, we discuss how a channel’s normal flow is re-established after a disconnection. And finally, we finish with how a cooperative channel closure happens. These topics are all covered in Bolt 2 for…
