Bitcoin's Layer 1, revered for its unparalleled security and decentralization, has faced scrutiny over its scalability, cost, and throughput limitations. These constraints catalyzed the emergence of alternative networks like Ethereum, designed with smart contracting capabilities at their core. However, the narrative is shifting. With the introduction of Layer 2 solutions that integrate DeFi functionalities to Bitcoin, it’s poised to expand its utility far beyond a store of value.
In this article, we delve into the intricacies of Bitcoin Layers, and explore some of the projects in the space we’re most excited about.
As a team that is continually researching new technologies and exploring promising narratives, we’re thrilled to expand our expertise in the Bitcoin economy and collaborate with key players building in this ecosystem.
Before delving into the nuances of Bitcoin Layer 2 solutions, let's take a step back and understand the core concept of Layer 2s. A Layer 2 is built on top of the base chain (Layer 1) to improve scalability and transaction throughput.
Bitcoin and Ethereum are Layer 1 protocols, serving as the settlement layer for all transactions on their respective networks. Layer 2 solutions offer a way to increase transaction speeds and scale the network while benefiting from the security of the main chain.
While numerous Layer 2 solutions, such as rollups, side chains, and channels, are already building on Ethereum, and Bitcoin Layer 2s have been in development for some time, several projects are now closer to launching and expanding Bitcoin's utility. However, scaling Bitcoin presents unique intricacies that need to be addressed.
The most crucial requirement for a Bitcoin Layer 2 solution lies in deriving its security from Bitcoin's own security model, a task that proves challenging in practice. To effectively secure a Layer 2, Bitcoin must possess the computational capability to validate the behavior of the Layer 2. However, Bitcoin's current computational capacity falls short compared to Ethereum's Layer 2 solutions.
For instance, Ethereum rollups derive their security from the Layer 1 by either verifying a zero-knowledge proof (zk-rollup) or confirming a fraud proof (optimistic rollup). Nevertheless, there are ongoing proposals aimed at enhancing Bitcoin's functionality to enable the base layer to validate zk-Proofs submitted by rollups. Additionally, initiatives like BitVM strive to implement fraud proofs without necessitating alterations to the base layer.
While solutions are emerging to address this challenge, they bring their own set of architectural choices and leverage novel technologies to find viable solutions. As the development of Bitcoin Layer 2s progresses, the ecosystem will need to carefully evaluate the trade-offs and implications of each approach.
Bitcoin's Layer 2 solutions face unique challenges in trying to improve upon the base layer. These challenges revolve around three main goals: handling more transactions, maintaining robust security, and ensuring that the system remains decentralized. Here's a simpler look at each goal:
By focusing on these three areas, Bitcoin's Layer 2 aims to enhance the base layer's capabilities while adhering to the principles of scalability, security, and decentralization. This approach ensures that the network can grow and adapt to new demands without compromising on its core values.
In this section, we explore a few Bitcoin L2s that we’re excited about, and provide a quick overview of the project.

Lava is designed to enhance access scalability to various blockchains. This network has the ability to accommodate any RPC and API in a flexible manner,. Lava boasts of a lightning-fast network that is hyper-scalable, and permissionless with nearly 100% uptime.
A Remote Procedure Call, or RPC, is a lightweight software communication protocol, that allows for developers to run code that can be executed on servers remotely.
On Lava, blockchain and rollup developers can quickly bootstrap a network of infrastructure providers, without waiting for major providers to add support. The protocol's initial focus is directed towards RPC infrastructure, a service that aids developers to access over 30 diverse chains, from EVM to Cosmos.
In this section, we break down the different architectural elements of the Lava Network:
Specs - Specs, otherwise called Specifications, are the foundational blueprints for Lava's multichain support, outlined in JSON format. These specifications delineate the minimum requirements necessary for an API to function on Lava effectively. Through these specs, Lava identifies the supported chains and methods while also setting up the associated costs, prerequisites, and validations. Each time the ecosystem requires a fresh API, a new specification is seamlessly integrated. This flexible method seamlessly weaves modularity into the protocol, guaranteeing that Lava stays up-to-date and flexible.
Peer-to-Peer Lava SDK - The Lava SDK is a decentralized, peer-to-peer blockchain RPC for developers who are exploring the cross-chain functionality the ecosystem is offering. It offers a simplified setup for multi-chain RPC, where adding a new chain can be done with a few lines of code.

The EigenLayer ecosystem has emerged as a crucial driver of innovation and expanding the capabilities of the Ethereum network. As a leading node operator, we have taken a strategic, Safety over Speed approach to identifying and onboarding some of the most exciting Actively Validated Services (AVSs) that are set to transform the industry.
Let's dive into the first batch of EigenLayer AVSs that Chorus One is registering:
1. EigenDA: Scaling Data Availability for Rollups [Onboarded]
At the heart of the scalability challenges faced by Ethereum lie the complexities of data availability. EigenDA aims to tackle this problem head-on by providing a secure and scalable data availability solution for optimistic and zero-knowledge (ZK) rollups. By leveraging the restaking primitive developed by EigenLabs, EigenDA empowers rollups to access lower transaction costs, higher throughput, and robust security across the EigenLayer ecosystem.
Why we onboarded EigenDA: As the first AVS to launch on the EigenLayer mainnet, and its impressive $1 billion in total value locked (TVL), we see immense potential in supporting EigenDA and positioning it as a preferred solution for leading Layer 2 ecosystems, including the OP Stack.
2. Brevis: Trustless Co-Processing for Data-Rich Applications [Onboarded]
Brevis belongs to a class of solutions that thrive within the EigenLayer ecosystem – co-processor networks. These specialized networks extend the functionality of a stack to handle computationally intensive tasks, such as verifying complex data points for decentralized applications (dApps).
Brevis tackles the challenge of "data-rich" use cases, where retrieving and validating on-chain data can be both time-consuming and costly. By leveraging a novel "propose-challenge" model, Brevis generates ZK proofs to ensure the accuracy of its results, empowering applications in DeFi, user-segment optimization, and beyond to operate in a truly trustless manner.
Why we onboarded Brevis: Our decision to onboard Brevis as its second AVS was driven by the project's open-source codebase and the alignment with the team's vision. As a modular and efficient solution, Brevis aligns perfectly with Chorus One's commitment to driving innovation and supporting the growth of the decentralized ecosystem.
3. Eoracle: Bringing Transparency and Security to Oracle Networks

Eoracle aims to address this issue by creating an Ethereum-native oracle solution that leverages the decentralization, transparency, and security of the Ethereum network.
Why are we onboarding Eoracle: As the "Data Validator" AVS operated by Chorus One, Eoracle connects node operators to compute, validate, and publish off-chain data to dApps in a secure and trustless manner. By tapping into the Ethereum validator set through EigenLayer, Eoracle represents a crucial step towards building a more robust and reliable oracle infrastructure for the decentralized ecosystem.
4. Lagrange: Cryptographically secured proofs for the Multichain Future
Inspired by Ethereum’s Sync Committee, Lagrange’s State Committee seeks to provide a robust, scalable, and shared security solution for cross-chain interoperability. This works by enabling multiple protocols to derive security from a shared security zone made up of a single, dynamic set of Ethereum nodes. Operators can deploy the Lagrange State Committees in combination with restaking through EigenLayer, to address the challenges with current approaches to cross-chain interoperability.
Why we are onboarding Lagrange: As the first zero knowledge AVS on Eigenlayer, we are excited to work with an innovative solution like Lagrange. With 15+ committed professional operators and over $2 billion in pledged security by leading LRTs, we feel confident in supporting Lagrange in addressing the security question in cross-chain interoperability.
5. AltLayer: Bridging the Rollup Ecosystem
AltLayer offers two key services that are highly relevant to the Ethereum ecosystem. The first is their Rollup-as-a-Service (RaaS) solution, which enables the fast and customized deployment of rollups. The second, and more pertinent to Chorus One, is their "Restaked Rollups" – a vertically integrated suite of three AVSs that leverage EigenLayer's shared security to support decentralized rollups.
Why are we onboarding AltLayer: AltLayer's Restaked Rollup solution addresses key challenges facing decentralized rollups, such as the need for a decentralized sequencer (SQUAD), a robust verifier (VITAL), and fast finality (MACH). By onboarding this comprehensive suite of AVSs, starting with their MACH AVS in this iteration, we aim to provide critical infrastructure and support to the broader rollup ecosystem, accelerating the growth and adoption of scalable decentralized applications.
6. Witness Chain: Incentivizing Fraud Proofs for Optimistic Rollups
Optimistic rollups offer a promising path to Ethereum scalability, but their security properties have been limited by the lack of clear incentives for validators to diligently search for and submit fraud proofs. Witness Chain addresses this challenge with its Watchtower protocol – a programmable, trustless, and decentralized service that uses a novel "proof of diligence" mechanism to incentivize validators to support optimistic rollups.
Why are we onboarding Witness Chain: By onboarding Witness Chain as an AVS, we aim to continue our ongoing commitment to strengthening the security and decentralization of the L2 ecosystem, which is a crucial component of Ethereum's scalability roadmap. As optimistic rollups continue to gain traction, Witness Chain's services will play a vital role in ensuring the long-term viability and trust in these scaling solutions.
Stay tuned for Part 2 of this series, where we'll explore the additional exciting AVSs that Chorus One is onboarding to the EigenLayer network, further expanding the potential of the EigenLayer and Restaking ecosystem.

We are thrilled to share the latest update from the EigenLayer ecosystem – a highly anticipated upgrade that promises to provide stakers with greater control and flexibility over their staked assets. Effective today, April 9th, the EigenLayer mainnet launch unlocks a suite of new features and functionalities for both stakers and node operators.
EigenLayer M2 builds upon the existing M1 contracts that have been operational on the Ethereum mainnet. This major upgrade introduces a crucial new capability: the ability for users to delegate their restaked Ethereum (ETH) or liquid staking tokens (LSTs) to the node operator of their choice.
And as one of the leading node operators, we’re thrilled to announce that users can now delegate their restaked Ethereum (ETH) and Liquid Staking Tokens (LSTs) to Chorus One!
Delegating to Chorus One is a seamless and secure experience. Users can easily delegate to Chorus one via any of the following options:
OPUS Pool is designed to make the restaking process effortless for our users. Here's a quick guide on how to delegate your assets through the OPUS Pool:
You can find the detailed, step-by-step guide for OPUS Pool here: https://chorus.one/articles/your-guide-to-opus-pool-stake-mint-oseth-and-restake-with-eigenlayer
Note: Restaking LSTs with EigenLayer is currently on hold and will resume once the deposit cap is raised. In the meantime, you are welcome to use OPUS Pool to stake any amount of ETH, mint osETH, and delegate your existing restaked LSTs.
Alternatively, you can directly delegate your assets to Chorus One via the EigenLayer dashboard. Here's how it works:
By choosing either OPUS Pool or Chorus One’s operator profile on the EigenLayer dashboard, you can seamlessly delegate your assets to Chorus One and benefit from our tailored approach, enhanced MEV rewards, and top-tier security measures.
Please Note: The upgrade doesn't yet allow Operators to earn yield for services provided to an AVS or to be at risk of slashing for Operator misbehaviors.
At the heart of the M2 upgrade is the introduction of delegation capabilities, empowering stakers to choose the node operator they wish to delegate their assets to. Specifically, the M2 contracts will enable users to deposit their Ethereum (ETH) or liquid staking tokens (LSTs) into EigenLayer through the StrategyManager (for LSTs) or the EigenPodManager (for beacon chain ETH). Additionally, stakers will now be able to withdraw their assets via the DelegationManager, regardless of the asset type.
For node operators, the M2 upgrade introduces the ability to opt-in to providing services for Actively Validator Services (AVSs) using the respective AVS's middleware contracts. However, the current iteration of the M2 contracts does not yet enable node operators to earn yield for the services they provide to AVSs or expose them to the risk of slashing for any potential misbehaviors.
In contrast to node operators who may prioritize onboarding as many AVSs as possible, Chorus One has adopted a more strategic and selective approach. Security is of paramount importance to us, and we meticulously vet each AVS before providing infrastructure support.
Our dedicated team thoroughly assesses the technical architecture and risk profile of every AVS under consideration. We leave no stone unturned, carefully evaluating factors such as the robustness of their systems, the soundness of their security protocols, and their overall risk appetite. Only those AVSs that meet our stringent criteria are granted access to our staking infrastructure.
This selective approach ensures that our users can have the utmost confidence in the management of their assets. By entrusting their stakes to Chorus One, our customers can rest assured that their funds are being handled with the highest levels of diligence and care, safeguarded by our rigorous vetting process.
To learn more about Chorus One's tailored approach to restaking, we encourage you to reach out to our team at staking@chorus.one. Our team will be happy to answer any questions you might have.
