In September, the cryptocurrency market experienced dramatic fluctuations, with both Bitcoin and Ethereum experiencing massive sell-offs at the beginning of the month. However, the Federal Reserve announced a 50 basis point interest rate cut last night, which became a turning point in the market and pushed the public chain sector to regain vitality.
In the Layer 2 field of Bitcoin, the vigorous development of expansion plans is particularly significant, and TVL (Total Locked Value) has increased significantly, attracting widespread attention from investors. At the same time, Ethereum’s Layer 2 network is under considerable pressure and is still down about 30% since its TVL high in June. Nonetheless, industry giants like Sony joining the Ethereum ecosystem have become a recent bright spot.
Although the overall crypto market value has shrunk, as the Fed's policy tone of rate cuts becomes clearer, technological innovations in the Bitcoin and Ethereum Layer 2 fields will undoubtedly become the key driving force for the growth of cryptocurrency market value in the future.
Ethereum Layer2 Status
For many, Ethereum represents the primary settlement layer on the Internet of Value. The network remains front and center for Web3 development and innovation. But it has issues with scalability, throughput, and high gas costs that make it difficult to use.
Ethereum is currently unable to scale effectively because its network infrastructure is limited by its design, which prioritizes decentralization and security over scalability. The Ethereum mainnet processes all transactions on a single layer, leading to congestion during periods of high demand. This congestion results in slower transactions and increased fees.
According to Etherscan data, Ethereum's highest gas fee today reached 32 Gwei, a 7-day high.
While solutions like rollups, sidechains, and the upcoming Ethereum 2.0 upgrade aim to address these issues, they introduce trade-offs and are still in the early stages of development or adoption. The network’s reliance on these complex and evolving solutions slows its ability to scale effectively in the short term.
Ethereum has been exploring various solutions to increase transaction speed and reduce fees, each with different tradeoffs. Here are the main solutions and the compromises they introduce:
Optimistic Rollups: Optimistic Rollups batch transactions and publish them to the Ethereum mainnet (L1) after execution off-chain. The batches will be considered valid unless someone challenges them within seven days. This approach reduces fees and increases speed, but introduces significant latency. Users must wait for the challenge period to end before transactions can be fully settled on the mainnet. Additionally, the responsibility for detecting fraud also falls on the user. Today’s Optimistic Rollups also rely on centralized orderers and proposers, which can lead to transparency and trust issues because the mempool (the queue of pending transactions) is not fully transparent.
Zero-knowledge (zk) Rollups: Zk Rollups also bundle and verify transactions before publishing a cryptographic proof to L1 that the executed state is correct. This approach ensures that the state submitted to L1 is accurate without the need for a challenge period. However, similar to optimistic Rollups, zk Rollups currently rely on a centralized sorter with an opaque memory pool and centralized proposers. This centralization may be a concern for users who prioritize decentralization and transparency.
Validiums: Validiums operate similarly to zk rollups, but only publish the state root to L1. The network itself is responsible for ensuring that chain data is available to users in order to settle back to L1. This reduces the load on the Ethereum mainnet and improves scalability. However, the compromise here is that the burden of ensuring data availability falls on the network. If the network fails to maintain transparency, users may have difficulty verifying state or recovering assets.
Sidechains: Sidechains are independent blockchains connected to the Ethereum mainnet via a bridge. They maintain their own consensus mechanisms and process transactions independently of Ethereum. Sidechains can provide faster and cheaper transactions, but there are significant trade-offs in terms of security. Because they rely on a separate consensus mechanism, they may not be as secure as Ethereum's mainnet. Additionally, the bridges that connect sidechains to the mainnet may be vulnerable to attacks, putting cross-chain transactions at risk.

Each of these solutions improves transaction speed and cost, but they also introduce new challenges, particularly in terms of security, centralization, and user trust. Balancing these factors is key to the continued development of Ethereum scalability solutions.
We know that Bitcoin has won the trust of crypto enthusiasts around the world with its unparalleled security and rock-solid decentralization mechanism. Ethereum, on the other hand, has attracted the favor of countless developers with its powerful smart contracts and vibrant ecosystem. If we can perfectly combine the two and create a modular protocol that integrates the advantages of Bitcoin and Ethereum, users and developers will be able to enjoy the best security, scalability, and interoperability on one platform. Such an ambitious innovation is the protagonist we are going to unveil today - Hemi Network.
Hemi Network Introduction
Hemi Network is a modular layer 2 network that facilitates Ethereum smart contract functionality secured by the Bitcoin network. The chain introduces the Hemi Virtual Machine (hVM), which integrates a full Bitcoin node within the Ethereum Virtual Machine (EVM), Ethereum's core smart contract engine. HVM allows developers to create smart contracts that interact with the Bitcoin state, unlocking Bitcoin-based DeFi applications including staking, lending markets, and a democratized MEV market.
Compared to other Layer 2 (L2) rollup solutions, the Hemi Network introduces a more decentralized approach to data publishing and verification, solving key issues that exist in current L2 setups:
Decentralized Roles: Introducing a decentralized approach where publishers handle key roles asynchronously, mitigating risks associated with centralized control in other L2 networks.
Incentivized Participation: Allows public participation by staking tokens using Ethereum-side validation contracts, promoting consistent and incentivized data sharing even during periods of increased fee activity.
Fault tolerance and reward system: Implement a system to discourage malicious behavior, slashing the stake of publishers who submit invalid data while rewarding challengers who discover faults, thereby promoting network integrity.
Efficient Ethereum Fee Management: Rewards are managed through Ethereum-side validation contracts, ensuring that publishers receive consistent incentives despite fluctuations in Ethereum fees.
Hemi's core features include:
Easy to develop
The Hemi Virtual Machine (hVM) integrates a full Bitcoin node within the Ethereum Virtual Machine (EVM), providing developers with a familiar programming interface while leveraging the power of both Bitcoin and Ethereum.
Bitcoin’s Programmability
Building with the Hemi Bitcoin Kit (hBK) provides smart contracts with a highly granular, indexed view of the Bitcoin state, unlocking Bitcoin DeFi applications that were previously impractical or impossible to execute via the EVM.
Bitcoin’s Superfinality
Hemi’s Proof-of-Proof (PoP) consensus mechanism ensures transactions surpass Bitcoin’s security levels in just a few hours.
Security is a core priority for the Hemi Network. To address the shortcomings of existing cross-chain solutions, Hemi operates as an Ethereum Layer 2 and is secured by Bitcoin's Proof of Work (PoW) through a protocol called Proof of Proof (PoP). PoP allows Hemi to inherit Bitcoin's strong security while maintaining Ethereum's flexibility. Here's how it works: Hemi miners publish the network's consensus data to the Bitcoin blockchain. When these blocks are confirmed by Bitcoin, they reach finality and receive the same level of security as Bitcoin itself. In addition, the Hemi Virtual Machine (hVM) also plays a key role. The hVM is a full Bitcoin node encapsulated in the Ethereum Virtual Machine (EVM) and connected to the Bitcoin P2P network, which enables Hemi to track the state of Bitcoin in real time. This setup ensures that Hemi has full knowledge of Bitcoin's state without relying on third-party services for data relay, thereby reducing the risk from external validators or relayers.
Trustless cross-chain portability
hVM’s unique awareness of the state of Bitcoin and Ethereum enables secure and seamless asset transfers between Hemi and other chains through its “tunneling” functionality.
Hemi’s direct connection to the Bitcoin state enables secure and efficient cross-chain functionality that was previously difficult to achieve. Here’s how it solves some of the main challenges in cross-chain interoperability:
Eliminate third-party risk: Hemi has built-in awareness of Bitcoin’s state, eliminating the need for third-party relayers, thereby reducing points of failure and increasing trustlessness. This enables the development of secure Bitcoin-based decentralized applications (dApps) directly on Hemi without the need for additional intermediaries.
Prevent consensus attacks: By publishing cross-chain transactions as proofs to the Bitcoin blockchain, Hemi ensures that these transactions inherit the security of Bitcoin. This greatly reduces the risk of decoupled assets in cross-chain transfers, a common vulnerability in many bridge protocols.
Decentralized liquidity through the tunnel system: Hemi's tunnel system provides a secure and decentralized way to connect Bitcoin and Hemi without relying on overcollateralization or centralized parties. Instead, the tunnel system uses liquidity providers (LPs) who are rewarded for providing BTC and HEMI tokens, making the process more decentralized and efficient. This eliminates the need to lock funds with a third-party custodian, enhancing trustlessness while maintaining the scalability of the system.
Using the Hemi Bitcoin Kit (hBK), developers can create custom tunnels based on their specific needs for security, cost, and speed. This flexibility enables developers to build a range of solutions within Hemi's secure framework, opening up new opportunities for innovation.
Scalability
Hemi allows external projects to create their own chains secured by Hemi technology, promoting Bitcoin security as a service and enhancing dual-chain interoperability.
Excellent asset handling capabilities
With Hemi, advanced on-chain functionality including routing, time locks, and cryptographic protection can be achieved, improving asset management and security.
While Hemi’s Tunnel system provides a more secure and decentralized way to transfer assets, it does much more than that. With real-time visibility into the state of Bitcoin, developers can build trustless dApps that leverage both the programmability of Ethereum and the security of Bitcoin. This makes Hemi a powerful platform for building more complex decentralized applications that leverage the best of both ecosystems. Ethereum was designed to be a world computer, but Hemi takes that vision one step further by integrating Bitcoin at the protocol level. Hemi’s unique architecture makes the blockchain ecosystem more secure, trustless, and scalable, while simplifying the development of Bitcoin-based technologies. It also makes the blockchain ecosystem less fragmented by bringing the Ethereum and Bitcoin ecosystems together. The Hemi Network combines the security of Bitcoin with the flexibility of Ethereum, marking a major leap forward in cross-chain interoperability. By leveraging the security of Bitcoin’s PoW (through its Proof-of-Proof consensus), and using innovative tools like the hVM and Tunnel system, Hemi reduces trust assumptions and enhances the decentralized nature of blockchain technology. Whether used to transfer assets or build complex dApps, Hemi provides a secure, efficient, and trustless environment for Bitcoin and Ethereum to thrive together.
Team Background
Hemi was founded by Jeff Garzik, a renowned early Bitcoin developer, and Max Sanchez, a blockchain security pioneer.
Jeff Garzik is an entrepreneur and software engineer. Jeff is the co-founder and CEO of Bloq. Jeff serves on the board of directors of Coin Center and is on the advisory boards of BitFury, Bitpay, Chain.com, Netki, and WayPaver Labs. Jeff has spoken on Bitcoin and blockchain at TEDx, State of Digital Money, and numerous Bitcoin conferences, and has given private briefings to corporations, governments, central banks, and hedge funds. Jeff Garzik received his degree in computer science from Georgia Tech in 1996.
Jeff has extensive experience in early Internet technology adoption. After helping to create CNN.com on the Internet in the early 1990s, he worked for several Internet startups and service providers. At the same time, he has continued to work on open source software engineering projects for more than 20 years.
His involvement in one of the most famous open source projects, the Linux kernel, led to a long tenure at Linux leader Red Hat during open source's most mature years. Today, Jeff's work can be found in every Android phone and Linux installation in the data center.
In July 2010, Jeff stumbled upon a post introducing Bitcoin. He immediately realized the potential of a concept that had previously been thought impossible - decentralized digital currency - and did the natural thing: develop Bitcoin open source software. This gave birth to micro-enterprises based on Bitcoin. Almost by accident, Jeff found himself at the heart of Bitcoin, a revolutionary global technological phenomenon.
“The passion we have for the projects we build is reflected in the quality and enthusiasm of our investors and ecosystem partners, who understand the uniqueness and value of Hemi’s approach to scaling and integrating two leading blockchain networks, adding to the incredible growth and vitality of this particular space,” said Jeff Garzik.
