Why did our channel get force-closed?

There are a bunch of possible reasons for a force close - I will elaborate on the most common ones.

⚠ This is a work in progress and will get expanded.

WHAT HAPPENED?
An HTLC (a lightning transaction) timed out, which means it did neither succeed in arriving at it's

Silent Payments

Receive private payments from anyone on a single static address without requiring any interaction or extra on-chain overhead.

Update: This now has a BIP and WIP implementation

Overview

The recipient generates a so-called silent payment address and makes it publicly known. The sender then takes a public key from one of their chosen inputs for the payment, and uses it to derive a shared secret that is then used to tweak the silent payment address. The recipient detects the payment by scanning every transaction in the blockchain.

Description

This gist contains 3 files that can be imported into postman to play with our api:

• grapqhql_api collection which has our queries and mutations
• devnet environment variables for local testing (uses regtest network)
• staging environment variables for testing against our staging endpoint (uses testnet network)

If you already have a domain name setup with Cloudflare.com, you can easily do that, for free, without paying a VPN.

Trusting the vpn provider VS trusting Cloudflare. If that's ok for you go on :)

(for the example my domain is spiritualcomputing.com, be sure to replace it with yours) :

Go to cloudflare, dns, add 2 A records to your domain

Design for a CoinSwap Implementation for Massively Improving Bitcoin Privacy and Fungibility

25/5/2020

Abstract

Imagine a future where a user Alice has bitcoins and wants to send them with maximal privacy, so she creates a special kind of transaction. For anyone looking at the blockchain her transaction appears completely normal with her coins seemingly going from address A to address B. But in reality her coins end up in address Z which is entirely unconnected to either A or B.

Now imagine another user, Carol, who isn't too bothered by privacy and sends her bitcoin using a regular wallet which exists today. But because Carol's transaction looks exactly the same as Alice's, anybody analyzing the blockchain must now deal with the possibility that Carol's transaction actually sent her coins to a totally unconnected address. So Carol's privacy is improved even though she didn't change her behaviour, and perhaps had never even heard of this software.
