On February 4, Muneeb Ali, the CEO of Trust Machines, shared his thoughts on social media platform X after attending the Satoshi Roundtable X in Dubai (February 1-6, 2024). His message paints a picture of renewed excitement surrounding Bitcoin, fueled by advancements in Layer 2 (L2) solutions, particularly within the Stacks L2 ecosystem, the potential of BitVM technology, and the upcoming Nakamoto upgrade.

Bitcoin Basics

Think of Bitcoin as a digital currency known for its security and independence from any central authority. It stores information about all transactions on a massive public ledger called the blockchain. However, Bitcoin has some limitations:

  • High transaction fees: As more people use Bitcoin, the network can get congested, leading to higher fees for processing transactions.
  • Slow transaction times: Verifying transactions on the main blockchain can take some time, which can be inconvenient for everyday use.

Enter Layer 2 Solutions

Imagine L2 solutions as alternate lanes that help ease traffic on the main Bitcoin highway (the blockchain). These “side streets” allow transactions to process faster and cheaper, ultimately making Bitcoin more practical for everyday use. However, traditional L2 solutions often rely on centralized components, which can compromise some of Bitcoin’s core principles.

Stacks L2: Bringing Smart Contracts to Bitcoin

Stacks is a unique L2 solution that aims to bring smart contract functionality (the ability to program automatic transactions based on certain conditions) to Bitcoin, without compromising its security and decentralization. It achieves this by creating a separate layer on top of Bitcoin, where smart contracts can run, while still anchoring all activity back to the main Bitcoin blockchain for security.

BitVM: Enabling Trustless Movement of Bitcoin to L2s

BitVM is a new cryptographic technology, currently under development, that focuses on enabling trustless movement of Bitcoin between the main blockchain and L2 solutions. This means you wouldn’t need to rely on any central authority to move your Bitcoin between the main blockchain and any L2 solution, including Stacks. While currently being explored within the Stacks ecosystem for its potential benefits, BitVM itself is not formally part of the Stacks project.

The Nakamoto Upgrade

The Nakamoto upgrade is a significant upcoming improvement for the Stacks L2 ecosystem. It aims to:

  • Boost security: By leveraging Bitcoin’s security directly, further enhancing the overall trust and reliability of the Stacks L2.
  • Increase transaction speed and reduce fees: Transactions on the Stacks L2 will become faster and cheaper, thanks to optimizations introduced by the upgrade.
  • Enable sBTC: This upgrade paves the way for the introduction of sBTC, a trustless, two-way Bitcoin peg on the Stacks L2. This means users can easily move their Bitcoin between the main chain and the L2, unlocking new possibilities for decentralized finance (DeFi) and other applications.

Ali’s Key Points

  1. L2s are gaining momentum: Muneeb’s post highlights the growing interest in L2s, with the L2 session at the Roundtable being the biggest ever. He specifically emphasizes the potential of decentralized L2 solutions like Stacks.
  2. Stacks L2, BitVM, and the Nakamoto Upgrade: A Powerful Combination: Muneeb believes that the upcoming Nakamoto upgrade, combined with existing technologies like BitVM, could significantly benefit the Stacks L2 ecosystem. This would enable the development of more powerful and versatile applications built on top of Bitcoin, while leveraging its security and decentralization.
  3. Investors are taking notice: Even Bitcoin-focused startups, particularly those within the L2 space, are attracting significant interest from investors who recognize the potential of L2s to unlock new use cases for Bitcoin.
  4. Collaboration is crucial: Muneeb emphasizes that successful L2s, like Stacks, benefit everyone in the Bitcoin ecosystem. Collaboration and shared resources are essential for the overall success of L2 solutions.
  5. Bitcoin’s dominance could rise: Widespread adoption of L2s, particularly those with strong security and decentralization features like Stacks, could attract more users and capital to Bitcoin, potentially boosting its market share. This increased demand could make your existing Bitcoin holdings even more valuable.
  6. A bright future ahead: Muneeb predicts a rapid emergence of new L2 solutions, with continued development in the Stacks L2 ecosystem and the potential impact of technologies like BitVM that enhance trustless interactions between the main chain and L2s. He sees this as a new chapter for Bitcoin, driven by innovation and collaboration


If you’re interested in Bitcoin, the L2 revolution, especially developments within the Stacks ecosystem, like the Nakamoto upgrade and its potential synergy with BitVM, is something to keep an eye on. It has the potential to make Bitcoin more user-friendly, versatile, potentially more valuable, and accessible for everyday use while staying true to its core values of security and decentralization. While the technical details might seem complex, the key takeaway is that exciting developments are on the horizon for Bitcoin, and L2 solutions like those in the Stacks ecosystem are at the forefront.
