On Friday, Nov. 16, the developers behind the full node projects Bcoin and Bcash announced an application that allows users to complete cross-chain atomic swaps between both the BCH and BTC chains. The Bcoin programmers have also released a guide, videos and code for beginners and experts who want to swap BTC for BCH in a decentralized fashion.

BCH and BTC Cross-Chain Swaps With No Middlemen
The Bcoin developers recently released an application for users who want to learn how to execute atomic swaps between the BCH and BTC blockchains. Cross-chain atomic swaps have generated a lot of buzz lately, as the process allows people to swap two different cryptocurrencies, but without the need for third parties. Both Bcoin and Bcash are full node BTC and BCH implementations built with Javascript/NodeJS. With the atomic swap application, the Bcoin programmers wholeheartedly believe that in order “to protect both users, there must be no scenario in which one person can control both coins at the same time.”
“Atomic swaps enable some of the coolest layer-two technology in crypto, like Lightning and DEXs,” the . “We put together an illustrated guide to walk you through the process, complete with code and videos.”
Bcoin’s written by Matthew Zipkin, gives readers a comprehensive look into the technology under the hood. Similar to other types of second-layer technologies, cross-chain swaps use a protocol called Hash Time Locked-Contract (HTLC). Bcoin’s website explains the process through written descriptions and shows visuals of Alice and Bob performing an atomic swap. The guide also shows how the script is written by creating HTLC scripts with the Bcoin and Bcash libraries. Additionally, the walkthrough details how to fund swaps and redeem them once the funds are sent to the designated addresses. The atomic swap templates are accompanied by a of the cross-chain trade.
Centralized Exchanges and Hacks Bolster
the Need for Atomic Swaps
Over the last year concepts such as cross-chain atomic swaps have been growing more popular because of issues with centralized exchanges, which are still being hacked to this day. The decred (DCR) development team was the a cross-chain atomic swap between DCR and LTC back on Sept. 20, 2017. In the Bcoin and Bcash atomic swap guide, Zipkin cites the decred atomic swap Github repository.
There have also been a few other individuals and teams from various cryptocurrency projects who have been attempting to produce viable and decentralized models. Three months ago, BCH developer Mark Lundeberg a proof-of-concept of a way to do peer-to-peer atomic swaps without an “obvious on-chain fingerprint.” Lundeberg’s “Swap Channels” essentially hide atomic swaps using ordinary payment channels.
The Bcoin application’s documentation further explains how users can install to Windows, Mac and Linux, with accompanying videos for each operating system. The platform’s developers have also released for programmers who want to integrate the protocol into websites or other types of applications. In addition, the Bcoin team said users can make requests at the and contributors can earn bounties.

Innovative technology companies are leveraging blockchain technology to build next-generation business models and Content Delivery Networks (CDNs) for video streaming, a multibillion-dollar industry that continues to grow. According to data revealed by Theta Labs, one of the companies covered below, the video content and streaming market accounts for 67 percent of current internet traffic and could reach 82 percent by 2020. The new players promise to decentralize global video streaming, while at the same time making it more efficient.
LBRY
According to Jeremy Kauffman, co-founder and CEO of the blockchain-based content distribution platform , blockchain technology could transform the monetization of online content by altering the way that creators get paid, and .
The LBRY protocol allows creators to publish online, making their content discoverable with a small payment in LBRY’s own cryptocurrency token. Viewers pay creators in LBRY tokens to see their work.
“[Blockchain technology] allows us to build technology that’s owned by the users rather than any one party,” Kauffman . “That’s the problem that blockchain [technology] solves.”
Kauffman explained that under the LBRY model, creators are paid without an intermediary taking an inappropriately large cut. Since LBRY is a protocol, the company can’t control what gets discovered.
Kauffman said that LBRY recruited 4,000 YouTubers in specifically targeted demographics, several of which have 500,000 or more subscribers, which seems a good first step toward challenging YouTube in its own turf.
Theta Labs
YouTube’s co-founder Steve Chen himself, as well as Justin Kan, co-founder of Twitch, are among the advisors of , a subsidiary of live video streaming company , which is announcing a new blockchain-based decentralized video streaming network.
“Theta’s innovation is set to disrupt today’s online video industry much in the same way that the YouTube platform did to traditional video back in 2005,” said Chen. “One of our biggest challenges had been the high costs of delivering video to various parts of the world, and this problem is only getting bigger with HD, 4K and higher quality video streams. I’m excited to be part of the next evolution of the streaming space, helping Theta create a decentralized peer-to-peer network that can offer improved video delivery at lower costs.”
Theta is developing a new blockchain-based network, outlined in the , which could enable users worldwide with unutilized PC bandwidth and resources to cache and relay video streams to others in the network, while mining Theta tokens at the same time, similar to bitcoin and Ethereum. According to the company, the new peer-to-peer decentralized network will allow for much more efficient, high-quality streaming without the need to develop expensive content delivery network infrastructure.
In December, Theta will implement its first generation of ERC20-compliant tokens on the SLIVER.tv platform. These application tokens can be used for virtual gifting and incentivizing streamers. Eventually, these ERC20 tokens will be 1:1 exchangeable for native Theta tokens when the new blockchain launches at the end of 2018.
“We’ve been on the cutting edge of live streaming technology, and by leveraging blockchain [technology] we will truly be able to transform the video and entertainment industry,” said Mitch Liu, co-founder and CEO of Theta Labs. “Theta will be uniquely built to leverage the incentive mechanisms of the blockchain, enabling end-users to contribute their excess PC bandwidth and resources to relay video streams to others and earn Theta tokens at the same time. It’s a win-win for all stakeholders in the ecosystem.
“We’re committed to solving the challenges of today’s video streaming industry,” Liu told bitcoin Magazine. “We think there’s a huge opportunity to democratize the video delivery infrastructure, to reward end users with excess PC resources and bandwidth to help stream to their neighbors and friends.”
“I think the Theta team is going to revolutionize video delivery with its new native blockchain,” Theta advisor and CEO told bitcoin Magazine. “I’m thrilled to be part of this innovative, organic platform to decentralize streaming. This will impact a number of industries from esports to advertising, benefiting our esports fans as well as influencers and content creators. I can see how Theta’s peer-to-peer mesh network will empower our G FUEL community, rewarding them with Theta tokens when they help stream to others in the network.”
Stream
Another new video platform, , has received $5 million to back its Ethereum-based Stream Token in an advisor round of funding led by blockchain investment firms including Pantera Capital, Fenbushi Capital and CoinFund, as well as individual participants like Jed McCaleb, David Johnston and Andrew Yashchuk.
Founded by , Stream wants to facilitate direct transactions between content creators and consumers with a zero-fee structure. Yu was a successful early cryptocurrency investor who became an internet celebrity with videos that received tens of millions of views. In 2011, Yu left his studies at Harvard and accepted a $100,000 , like Ethereum creator Vitalik Buterin before him, eventually launching and Stream.
The Stream Token to allow digital media creators to earn a fair living from their work, without being exploited by streaming platforms that take unreasonably large shares of their revenue. It is also designed to free content creators from the strictures of advertising models that limit creativity and freedom of expression.
“Stream Token is part of the larger Silicon Valley movement to fulfill the original intention of the internet: universal access to information. We can finally reward those who share information without curtailing freedom of expression. Content creation doesn’t have to be a zero sum game,” said Greg Kufera, CTO of Stream. “And we’re ensuring it won’t be.”
