Welcome to the latest edition of the Lightning Lab, a newsletter filled with Lightning Network updates, community coverage, and, of course, memes! In this issue, we discuss how the Lightning Network community continues to build and grow despite broader market turbulence, a State of Lightning report from Arcane Research, a call to action to build Decentralized Finance on Bitcoin and Lightning from Ross Stevens, Nic Carter, and Allen Farrington, and a host of new network statistics and ecosystem updates including a Bitcoin 2022 recap!
Back to the Bitcoin Future 🚙🔌
Summer 2022 has kicked off with global markets in turmoil: inflation at 40 year highs, real rates moving higher as the economy begins to slow, NASDAQ down 30% from all-time highs, and general strife in the altcoin market. At the same time, the Lightning Network has been unaffected as our community of builders continues to focus on building the future of money. Public network capacity has grown by 20% already YTD to over 4000 BTC, and, like Doc and McFly in a DeLorean getting struck by Lightning, we’re just getting started. 🤓
This past weekend, Ross Stevens, Nic Carter, and Allen Farrington wrote a paper titled “On Impossible Things Before Breakfast.” They follow-up an insightful critique of the Terra stablecoin collapse and DeFi in general with a focus on the signal in the noise: the Lightning Network, Taro making Lightning a multi-asset network, and the possibilities that will be built on said network. The authors want us to:
“Imagine an ecosystem in which the building blocks of financial and capital markets are freely accessible to all without navigation of technical bottlenecks or economic middlemen; in which their workings are transparently inspectable and auditable on the basis of free and open-source code; in which the architecture of all marketplaces operate on these principles; in which this constitution lends itself naturally to programmability at origin and interoperability thereafter; and, in which, due to the combination of the aforementioned factors, no individual or entity can maliciously or politically impact market activity in any form, including advantaging themselves or disadvantaging others.”
That’s the future we’re going back to, building an ecosystem of globally available, permissionless, and universally verifiable financial services. Already today, as the authors note, “The Lightning Network will allow anyone – individuals, SMEs, institutions, etc. – to send domestic or international payments of any size, with unlimited frequency, without bank intermediaries, nearly instantly, and essentially for free.” We look forward to expanding on that ecosystem with Taro soon. 🍠
Several weeks ago, Arcane Research published their State of Lightning Volume 2 report that went in depth on the usage of the Lightning Network, and highlighted exactly the builders that continue to propel us forward!
The report includes a foreword from the inimitable Lyn Alden, an Ecosystem Overview, aggregated transactional data from private Lightning companies, discussion about the fundraising activity in the Lightning Network, and a 🔥 update to their market map.
Their research uncovered a new data point in favor of one of our favorite themes: Lightning’s high utility-to-speculation ratio. The below chart shows Lightning payment volume in two categories: speculative usage with exchanges (gray) and non-speculative usage everywhere else (black).
This makes it even more clear that while speculators come and go, the Lightning Network has found product market fit with a core group of transactors who are growing its network effect by transacting on a daily basis. We discussed this network effect in depth last November, specifically how large capital increases in public network capacity are actually a lagging indicator of increasing network utility. This utility will only continue to grow as those transactors convince friends, local merchants, and new businesses to join the network. We can’t wait to see what this chart looks like in 6 months!
We highly recommend reading the full report to understand exactly what’s going on in the Lightning ecosystem, where growth is coming from, and what to expect next. Congratulations to Arcane Research for another great report, we look forward to more research institutions producing content like this as the network continues to grow! 📈

Now's the Time to Build With Lightning ⚡️🍠
Builders in the Lightning ecosystem continue to build like the future depends on it! In April, the global Bitcoin community descended upon Miami for Bitcoin 2022, and, just like last year’s Bitcoin 2021 conference, Lightning was ubiquitous. The conference sold tickets over Lightning powered by OpenNode, vendors inside the conference sold refreshments over Lightning powered by Ibex Mercado, and Lightning developers were a mainstay on stage. Not only was Lightning ubiquitous, however, but the accelerating pace of adoption this newsletter has cataloged over the last year seems to have itself accelerated: new Lightning launch and fundraise announcements are happening faster and at a bigger scale than ever before!
Lightning Labs CEO Elizabeth Stark gave a keynote featuring the teenage founders of GenBitcoin, Ishaana Misra and Autumn Domingo. They asked about her vision for hyperbitcoinization, which led to an in-depth discussion into what “bitcoinizing the dollar” means with the new Taro protocol. They also discussed what makes Lightning different from the rest of the crypto ecosystem, with a focus on how the Lightning community prioritizes Number of People Go Up and growing bitcoin’s network effects, as opposed to building tokens on tokens on tokens with no real utility.
Elizabeth also spoke about Taro and bitcoinizing the dollar on Bloomberg TV, about the Future of Bitcoin and Lightning at Crypto Bahamas, and was named one of the top 100 most influential women in finance by Barron's!
Lightning Labs CTO Laolu Osuntokun gave a keynote on the new Taro protocol. After explaining that taro is a root vegetable with a taproot structure eaten across Africa, South America and Asia (where Lightning is being adopted at a rapid pace), and primarily produced in his home country of Nigeria, he walked the crowd through the protocol design and how Taro assets natively integrate with the Lightning Network. The audience at the high-signal Open Source Stage received Laolu’s expert tutelage in cutting-edge research at his customary Lightning speed!
Even those outside of the core Lightning community can see the rapid pace of growth and development, with world-renowned investors like Cathie Wood bullish on the prospects of what new developers can build with Lightning technology.
And for good reason, as the Lightning aspects of the conference convinced new developers to try out tools like Lightning Polar (created by Lightning Labs’s own Jamal James) for the first time. They were amazed at the frictionless experience, a testament to all the builders in the community!
A little over a month later, central bankers from 44 countries around the world traveled to El Salvador for a meeting of the Alliance for Financial Inclusion. Included in the three day agenda was a heavy dose of Bitcoin education, Lightning payment experiences, and testimony from residents of Bitcoin Beach in El Zonte. Probably nothing… 🚀
Bitcoin 2022 made it clear that Lightning adoption is progressing at a breakneck pace, that a developer friendly experience is the key to such adoption, and that the next generation of developers are ready to help take the network to the next level. Onwards! ⚡️📈👏
Lightning Labs News
Product
Over the past quarter, we have been making consistent improvements to Terminal to better meet the needs of node operators. The Loop UI received a major upgrade, making it easier than ever to manage liquidity and ensure high reliability for received payments. Additional improvements include improved stability and persistence of the connection to an operator’s node, Lightning send and receive functionality, the ability to open and close channels, ability to set fees within channels, and a channel details menu. Plus, for more security and flexibility, we have created the option for node operators to provide read-only access to Terminal. We will continue to listen to user feedback to prioritize changes and new features. Please continue to reach out with any questions or feedback through our Slack channel.
For Lightning Loop, we recently increased the max swap size from 0.6 BTC to 1.2 BTC to meet the needs of users who want larger swaps. Further, in the latest client release, we’ve added experiments around pathfinding to increase reliability especially for larger Loop swaps.
We released lnd v0.14.3, a minor release focused on a series of bug fixes including: remote signer fixes, proper handling of 3rd party anchor sweeps, and a key payment consistency fix.
Finally, we also want to highlight our Taro documentation on the Lightning Labs Builder Guide as a great reference for any developers who want to dive deeper into the Taro protocol design, and our newest developer video walking through the Taro protocol. These documents should provide a more concise overview of the protocol, but the Taro BIPs can provide more detail if necessary.
Community
We started an LND PR Review Club, where external developers can learn our codebase by performing PR reviews guided by frequent contributors.
The Review Club will happen every two weeks on Thursdays at 10am PT / 1pm ET / 5pm UTC in the lnd slack channel #review-club. We welcome suggestions for PRs and volunteers for hosting sessions.
