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.

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 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.

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?
