 The next question comes from SesameMeow asks, Lightning on Bitcoin on Liquid, and it has a quote from Adam Back. Lightning on Bitcoin on Liquid, Liquid being a side-chain connected to Bitcoin, which trades in liquid Bitcoin or LBTC. Bitcoin layers connecting and converging. People may not know that Lightning can bridge multiple networks. How does this work? Are there multiple Lightning networks? How do they interact with each other? This is a really interesting early proof of concept. Not many people realize that Lightning is not just a Bitcoin project. Lightning is an interledger project. It is basically a protocol that can connect different blockchains to each other. Any blockchain that can support a few basic primitives, specifically the ability to have a time-locked contract that can be unlocked using a hash-pre-image, also known as a hash-time-locked contract, or HTLC, and you can build these with very simple primitives. Basically, if Bitcoin can support it, a lot of other blockchains can support it. Bitcoin script and language is quite simple. Any blockchain that can support these fundamental primitives can then implement the Bolt protocols. Bolt is the basics of Lightning technology and is the interoperability specification or standard for Lightning. If a project implements the Bolt protocols, then they can participate in the Lightning network. The question from Sesame is, are there multiple Lightning networks? How do they interact with each other? No, it is one network. The interesting thing is that you can have channels that connect peers that are trading or making payments with Bitcoin. Those channels are anchored and enforced by the Bitcoin blockchain. You can also have peers today that have payment channels between them using Litecoin. When the Lightning network launched, it was Bitcoin and Litecoin. Those peers are exchanging payments through payment channels that are anchored and secured by the Litecoin network. Recently, with the introduction of liquid BTC clients that can implement the Bolt protocols, you can have nodes that have payment channels with each other that are on the liquid sidechain, which is a blockstream project for connecting exchanges together, primarily large liquidity providers. If you have nodes that operate on the Bitcoin blockchain, the Litecoin blockchain, and the liquid blockchain, or any pair of those, then that node can have payment channels on Bitcoin and payment channels on Litecoin or liquid, and can then route payments between them, which means that you can send a payment. By sending it via this node, you can originate a payment in Bitcoin that then gets transmitted in liquid Bitcoin or Litecoin at the other end. Theoretically, at least, you could write smart contracts that implement this in Ethereum, so you could route payment channels that make payments from Bitcoin that get paid in Ether. You could do this across any limited number of blockchains. As long as there are some nodes that enable you to make that conversion with a specified exchange rate, then you can route your payments and effectively use the Lightning network also as a decentralized exchange. This is one of the really fascinating features of Lightning, which is that in fact, it is an interledger protocol between multiple different blockchains, and as a result, can help bridge these blockchains and allow payments to flow in multiple currencies and be exchanged by this decentralized exchange capability. With all of the advantages of privacy and all of the advantages of very, very fast payments, with very, very low to zero fees. Now, imagine for example where you have a payment that originates in Bitcoin, gets routed through a liquid node. Now, liquid also has confidential transactions, so you could use that capability potentially in the future to increase the privacy and then route it back out into a Bitcoin payment. Now, effectively, you've introduced a privacy hop in the middle of a Bitcoin transaction. You can also use it to do the equivalent of atomic swaps, because every payment channel that converts prices is effectively an atomic swap. So you can use it to exchange one currency to another. You could have a Litecoin, Liquid, and Bitcoin node simultaneously connected to the network, and then you can very quickly and very cheaply exchange Bitcoin for Litecoin for Liquid. This is kind of one of those hidden features of Lightning Networks that most people don't know about, but which could become a very powerful feature in the future. And this is not limited to Lightning. Any layer-to-technology that uses these kinds of fundamental cryptographic primitives, like time locks and hashes and threshold signatures and things like that, could support some form of payment channels, as long as they are based on an interoperable standard, and in the case of Lightning, that's called BOLD. Then these nodes can talk to each other, and they can effectively exchange currencies. Russ asks a follow-up question on the Lightning-based exchanges. How does one control the pricing? As a follow-up to the previous question, how do you control the pricing or exchange rate between two currencies when you're swapping them on the Lightning network? That's one of the things you simply do with the routing protocol, which means that when you pick a path, the node that you pick to do the exchange advertises its exchange rate just like it advertises its fees, and therefore you can select a path that gives you the optimal exchange rate.
