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.

Grassroots outreach and action, especially through local Bitcoin meetups, have been instrumental in transforming Bitcoin from a niche technology into a permanent fixture in finance.

Bitcoin's narrative is not shaped, for example, by an official marketing department or spokesperson, but by the persistent efforts of everyday people like you. This is why we are launching Blockstream Local, a new initiative designed to empower communities with the necessary tools and support to carry forward the legacy of grassroots Bitcoin education.

By joining Blockstream Local, your meetup will receive curated education resources, early access to new Blockstream products, and the ability to create a revenue stream, all of which can significantly amplify impact in your local community.

As we enter a new era powered by Bitcoin, those who have historically been left behind could lead the charge in scaling financial trust (by disintermediating it) not just locally but on a global scale. In doing so, they would transform from their status as outsiders into outstanding examples for us all of how to build fairer and more inclusive financial systems.

Today, we’re launching the next generation of Bitcoin mining investments: the Blockstream Mining Note 2 (BMN2). It offers investors direct exposure to hashrate generated at our Bitcoin mining facilities through a tradable security token on Liquid.

BMN2 builds on the success of BMN1, which recently matured, generating over 1,212 BTC with net returns of up to 102% over its three-year term. BMN2 offers a similar structure but extends the investment period to 48 months.

Starting today, our fully open-source hardware wallet, Blockstream jade, supports Mininoscript.

Use timelocks and more complex multisig arrangements for greater peace of mind and planning by pairing Jade with the Liana software wallet.
