A description of known problems in Satoshi Nakamoto's paper, "Bitcoin: A Peer-to-Peer Electronic Cash System", as well as notes on terminology changes and how Bitcoin's implementation differs from that described in the paper.

Abstract

The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power.

To remove a submodule you need to:

• Delete the relevant section from the .gitmodules file.
• Stage the .gitmodules changes git add .gitmodules
• Delete the relevant section from .git/config.
• Run git rm --cached path_to_submodule (no trailing slash).
• Run rm -rf .git/modules/path_to_submodule (no trailing slash).
• Commit git commit -m "Removed submodule "
• Delete the now untracked submodule files rm -rf path_to_submodule

burn-btc: create a bitcoin burn address

By James C. Stroud

This program requries base58 (https://pypi.python.org/pypi/base58/0.2.1).

Call the program with a template burn address as the only argument::

#include <QtQml/QQmlApplicationEngine>
#include <QtWebEngine/qtwebengineglobal.h>
 
int main(int argc, char *argv[])
{
  QGuiApplication app(argc, argv);
  QtWebEngine::initialize();
  QQmlApplicationEngine appEngine;
  appEngine.load(QUrl("main.qml"));
