As the Liquid Network's technical provider, Blockstream is committed to making it easier to build on Liquid and the broader L2 ecosystem. These recent development efforts have culminated in the new Liquid Wallet Kit (LWK), a collection of Rust tools to build Liquid wallets.

The aim of LWK is to provide all the necessary building blocks for Liquid wallet applications development and simplify the life of developers by addressing common pain points of the current tooling. We want LWK to be a reference tool that can help reduce friction for Liquid integration, define ecosystem standards and productionize Liquid innovation.

Last year, we improved upon Green's security and privacy fundamentals by wholly redesigning the mobile wallet for a more refined self-custody experience. In the latest 2.0.0 release of Green Desktop, users will get this same refreshed experience, including a more user-friendly interface for hardware wallet users, the ability to have one recovery phrase for both your Bitcoin and Liquid accounts, an all-new dashboard with Bitcoin price and fees, and much more!

Yesterday, we joined forces with leading digital assets platform Bitfinex Securities for the launch of ‘Bitcoin Capital,’ a new virtual roundtable series designed to explore the dynamic intersection of blockchain technology and traditional finance.

The first hour-long session featured legendary cryptographer and Bitcoin pioneer Dr. Adam Back, CEO and co-founder of Blockstream, and Paolo Ardoino, CTO of Bitfinex Securities. Together, they explored a range of topics, touching on everything from the projected impact of the recent Bitcoin ETF approvals to the role of tokenization in transforming the issuance of traditional financial instruments like securities, bonds, and even mortgages.

A proposed solution to #Bitcoin scalability and lack of expressivity is the addition of new covenant opcodes. Each proposal has its own advantages, disadvantages, and trade-offs, but all include a certain level of Miner Extractable Value (MEV) risk. Given these inherent traits in the nature of programmable money, what level of risk is acceptable?

We explore this question by examining MEV and the limitations of Bitcoin Script. We also look at some of the covenant proposals, such as CAT + CSFS and CTV, as well as the new Simplicity blockchain language, an alternative to Bitcoin Script that is more expressive with static analysis and formal verification.

The idea of advancing Bitcoin’s smart contract functionality is undeniably promising and exciting. But it’s important to acknowledge that each new proposal carries some degree of MEV risk—albeit likely not to the extent that we see on other chains. As we think about bringing more programmable money to Bitcoin, there are questions we have to ask:

- Can we build a protocol with zero MEV risk, or is this an unattainable ideal?
- Given the inherent risks of MEV in many proposals, what level of MEV risk is acceptable?
- And finally, what represents the simplest proposal that offers the greatest degree of expressivity?

On Bitcoin’s 15th birthday, we celebrate a tremendous year in Bitcoin development. We formalized the Blockstream Research team, revamped the Blockstream Green UX, and built out Blockstream Jade to service a planetary scale.

We launched the Greenlight Lightning-as-a-Service, fully open-sourced the Liquid Network functionary code, and helped integrate splicing to the Lightning Network spec through the Core Lightning development process.

We’re grateful to all of you who HODL’d alongside us throughout the journey. Thank you for engaging with our content, sharing your feedback, contributing to the open-source projects we maintain, and always challenging us to make Bitcoin infrastructure better and more accessible.

We’re excited to keep pushing towards hyperbitcoinization in 2024, and we hope you’ll join us for the ride! 📈

After several months of gathering feedback and additional testing, Greenlight is now officially available for commercial-grade use worldwide.

Greenlight is a Lightning-as-a-Service (LaaS) solution that offloads the complexities of operating a Lightning node to Blockstream experts while keeping keys in the user's control for greater security.
https://image.nostr.build/e530aac4e34748b7c5c22527b691e8ec289cd572cc8edd985f4d99f2827bd511.png

For Lightning developers, this not only reduces the risk and liability of holding user funds but frees up resources that would otherwise go to node operations—so that you can focus on your business and create the best app possible.

In the spirit of Bitcoin and to encourage the growth of the non-custodial Lightning options, we are offering a free Greenlight plan designed to empower small businesses. The plan allows developers to deploy up to 1,000 on-demand nodes.

For enterprises with higher volumes, we offer custom pricing plans that expand the node limits and provide uptime and availability guarantees.

Good key management lies at the heart of proper bitcoin custody and keeping your funds safe. This is why we have always been passionate about building better custody solutions, whether through creating feature-rich wallets like Green and Jade, contributing to open-source federated networks such as Fedimint and Liquid, or developing cutting-edge signature schemes like MuSig2 and ROAST.

Our new partnership with Swan, which helps bring collaborative custody to Bitcoin novices and veterans alike, continues this tradition. At the center of the initiative is Blockstream Jade, our entirely open-source hardware wallet, which will be the sole signing device featured in Swan Vault upon its debut.
