Stable Diffusion is an AI art generation model similar to DALLE-2.
Here are some prompts for generating art with Stable Diffusion. 

Example:

- A ghostly apparition drifting through a haunted mansion's grand ballroom, illuminated by flickering candlelight. Eerie, ethereal, moody lighting. 
- portait of a homer simpson archer shooting arrow at forest monster, front game card, drark, marvel comics, dark, smooth
- pirate, deep focus, fantasy, matte, sharp focus
- red dead redemption 2, cinematic view, epic sky, detailed, low angle, high detail, warm lighting, volumetric, godrays, vivid, beautiful
- a fantasy style portrait painting of rachel lane / alison brie hybrid in the style of francois boucher oil painting, rpg portrait

Offline Transactions in Mimblewimble

Mimblewimble is a blockchain protocol that improves on bitcoin's privacy and scalability by using pedersen commitments, schnorr signatures, and a novel technique called 'cut-through'. These benefits have come at a steep cost. Building transactions have thus far required interaction between the sender and receiver to create the outputs and collectively sign the transaction. We present here a method of achieving one-sided transactions while minimizing the impact on the scalability and privacy of mimblewimble.

Current Protocol

Like bitcoin, Grin uses a UTXO model. Transactions are created by including inputs to spend, creating new outputs of equal or lesser value, and signing and building rangeproofs to verify ownership of the inputs.

Unlike bitcoin, Grin uses confidential transactions, so the inputs and outputs are pedersen commitments (r*G + v*H). Instead of the signatures being added to the inputs, there is only one signature per transaction, which is part of the

Intro

This guide is specific to getting LND 0.5-beta and Bitcoind running on Ubuntu 16.04 LTS for mainnet. It is aging rapidly and includes steps not necessary on newer versions of LND. As of April 2021 it is very out of date for bitcoind. As of December 2021 it is outdated for LND too.

Original installation guide:

• https://github.com/lightningnetwork/lnd/blob/master/docs/INSTALL.md

This guide is broken into the following sections:

• Install bitcoind and set to start automatically
• Install development tools and dependancies
