### (Optional) Autounlock LND wallet

Since version 0.13, LND can read the wallet password from a file.
There are many options to (more or less) securely store the password in a file.
LND [describes two options](https://github.com/lightningnetwork/lnd/blob/master/docs/wallet.md#auto-unlocking-a-wallet): an easy but insecure one, and a more secure option using additional software like a password mangager.

We explain an easy approach that is pretty secure for remote attacks (the main threat in our opinion), but not very secure if someone gains physical access to your RaspiBolt node. The main advantage of this method is that only the `root` user has access to the password, and it is exposed to the `bitcoin` group on startup in memory only.

* As user "admin", create a new directory, prepare it and create an empty file to which only `root` has access

bitcoind-monitor.py

Updated to work with Bitcoin Core 16.0 and newer.

This is a script written in Python intended to run alongside a Bitcoin node and export statistics for monitoring purposes. It assumes the existence of bitcoin-cli in the PATH and access to the RPC interface over localhost.

It tracks stuff like: block height, difficulty, number of peers, network hash rate, errors, uptime in seconds, mempool size, size of recent blocks, number of transactions within blocks, chaintips, total bytes received and sent, and transaction inputs and outputs. These Bitcoin metrics are refreshed once every 5 minutes.

# Review of the "Virtual Markets Integrity Initiative" of the Office of the New York State Attorney General
## Mid-term assignment DFIN-522 by Roland Stadler, University of Nicosia


## Introduction
As one of the financial centers of the World, the State of New York has a defining role dealing with financial markets and its service providers. It is a leading player in creating legislation regarding consumer protection and prosecuting fraudulent market participants. The Office of the Attorney General (OAG) "is charged with the statutory and common law powers to protect consumers and investors" (1). As "People's Lawyer" it strives to protect customers of virtual currency platforms (exchanges) and to increase transparency by its "Virtual Market Integrity Initiative" report.
