Solving the 0-conf problem using forfeits

by /u/awemany

Overview

The problem of ensuring good security for unconfirmed transactions in Bitcoin is repeatedly discussed in the community. Right now these so-called 0-conf transactions are usually expected to be of low risk in the case of small amounts and face-to-face interaction of merchant and customer.

The PATH is an important concept when working on the command line. It's a list of directories that tell your operating system where to look for programs, so that you can just write script instead of /home/me/bin/script or C:\Users\Me\bin\script. But different operating systems have different ways to add a new directory to it:

Windows

1. The first step depends which version of Windows you're using:

• If you're using Windows 8 or 10, press the Windows key, then search for and

0-Confirmation Double-Spend Protocol

The problem

Bitcoin-accepting merchants want to receive payment and provide services instantly. However, block construction times can be as much as 10 minutes after the moment a bitcoin transaction is broadcast. In the time after a transaction but before a block’s creation, that transaction can be superseded by another transaction with a larger fee paid to miners.

With the change in the mempool protocol from first-seen-first-included and the rejection of conflicting double spends, to the inclusion of double spends and prioritizing transactions with larger fees attached, 0-conf transactions can no longer be reasonably secure for any sized transaction.

The idea of replace-by-fee was that miners will follow their immediate self-interest, and if miners sporadically act that way, could potentially decrease trust in the system. Now that this approach has been assumed and is the default behavior of miner software, we might consider amending t

How to automatically start ssh server on boot on Windows Subsystem for Linux

Microsoft partnered with Canonical to create Bash on Ubuntu on Windows, running through a technology called the Windows Subsystem for Linux. Below are instructions on how to set up the ssh server to run automatically at boot.

1. Edit the /etc/ssh/sshd_config file by running the command sudo vi /etc/ssh/sshd_config and do the following
   1. Change Port to 2222 (or any other port above 1000)
   2. Change PasswordAuthentication to yes. This can be changed back to no if ssh keys are setup.
2. Restart the ssh server:
   • sudo service ssh --full-restart
3. With this setup, the ssh server must be turned on every time you run Bash on Ubuntu on Windows, as by default it is off. Use this command to turn it on:
