In responses provided to Bitcoin.com News, La Rose, who is also the founder of the EOS Network Foundation, said such an integration not only helps sustain miner revenue but also “enriches the blockchain ecosystem by boosting the overall utility and adoption of Bitcoin.” Overall, this integration results in what the Exsat CEO calls a “triple win” for the Bitcoin network: enhanced scalability and engagement, increased functionality and adoption for L2s, and diversified revenue streams for miners.

Concerning the impact of the recent halving event on miners, La Rose said that while the reduced block rewards are likely to favor established miners in the short term, the latest halving could also lead to unexpected shifts in the mining landscape. For instance, major miners may scale back operations to conserve resources during bearish periods. This, in turn, will open opportunities for smaller mining collectives, which are not encumbered by high overhead costs.

Elsewhere in his written responses, La Rose offered his views on the prospects of Bitcoin decentralized finance (defi) overtaking Ethereum defi, as well as why the Bitcoin network is not able to support complex smart contracts at scale. Below are La Rose’s answers to the questions, presented verbatim.

Yves La Rose (YLR): Bitcoin’s design prioritizes security and decentralization over scalability and complex functionality. Its scripting language is intentionally limited, making it challenging to support complex smart contracts directly on the Bitcoin main chain. This simplicity, while foundational to Bitcoin’s unmatched security, restricts the functionality needed for more complex decentralized applications (dapps).

Ethereum was invented specifically to address these limitations. Vitalik Buterin recognized the need for a more flexible and powerful blockchain platform capable of supporting complex smart contracts and dApps, which is what led to Ethereum and eventually DeFi.

The introduction of protocols like Exsat is crucial in addressing Bitcoin’s limitations. Exsat extends Bitcoin’s capabilities by incorporating a hybrid consensus mechanism and supporting Ethereum Virtual Machine (EVM) compatibility with Bitcoin, thus bridging the gap for more complex applications.

YLR: Absolutely, the reduction in miner rewards due to bitcoin (BTC) halving necessitates new revenue models for miners, and this will undoubtedly act as a catalyst for innovation within the Bitcoin ecosystem. As transaction fees become a more critical component of miner revenue, there’s an increased incentive to adopt and develop solutions that enhance transaction throughput and network efficiency. This includes integrating with advanced Layer 2 solutions, which not only improve scalability but also expand the functionality of Bitcoin to include features like ordinals and BRC-20 tokens—despite their current criticisms for using up block space.

Our Exsat platform plays a pivotal role in this transition, serving as a docking layer that facilitates seamless interactions between Bitcoin and these Layer 2 technologies. This integration not only helps sustain miner revenue through more diverse transaction fees but also enriches the blockchain ecosystem by boosting the overall utility and adoption of bitcoin. The result is a triple-win: enhanced scalability and engagement for bitcoin, increased functionality and adoption for Layer 2 solutions, and more robust and diversified revenue streams for miners, all of which secure network operations and drive further innovation.

YLR: Exsat is a novel Docking Layer solution designed to address the core challenges of trust, functionality, scalability, utility, and interoperability in the Bitcoin ecosystem. By extending Bitcoin’s data consensus through a hybrid consensus mechanism, Exsat combines the strengths of Proof of Work (PoW) and Proof of Stake (PoS). This hybrid approach not only maintains Bitcoin’s robust security but also enhances its capabilities for more complex transactions and smart contract applications.

The Docking Layer concept of Exsat is central to its ability to link Bitcoin with its Layer-2 (L2) solutions. The Docking Layer serves as an intermediary layer that synchronizes Bitcoin’s Unspent Transaction Output (UTXO) data into an on-chain structured database leveraging the high-speed low-latency capabilities of EOS RAM. This is achieved by involving mining pools as synchronizers, which ensures that all data is generated directly from raw BTC blocks and supported by consensus. We recently announced Spiderpool, which has the 7th-ranked Bitcoin hash power in the world, as our first validator for Exsat.

By providing a comprehensive index of Bitcoin’s UTXO data and ensuring its availability on-chain, Exsat allows for the seamless integration of various L2 solutions. This integration facilitates the development of decentralized applications (dapps) that can operate across different blockchain ecosystems while leveraging Bitcoin’s security and data integrity. Additionally, Exsat’s architecture supports the creation of customizable BTC Layer-2 solutions, such as Zero-Knowledge (ZK) rollups and sidechains, making it easier and more efficient for developers to build and deploy scalable applications.

For the future of the Bitcoin ecosystem, Exsat represents a significant leap forward. It enhances Bitcoin’s utility beyond being a store of value, paving the way for more advanced applications and services. By addressing the scalability and interoperability issues, Exsat is poised to unlock new economic opportunities and drive mass adoption of Bitcoin-based technologies. The Docking Layer approach ensures that Bitcoin can remain at the core of a diverse and interconnected blockchain ecosystem, fostering innovation and expanding its use cases​.

YLR: Ethereum currently leads in DeFi due to its advanced smart contract capabilities and extensive Layer-2 ecosystem. However, Bitcoin DeFi (BTCFi) has the potential to rival and possibly overtake Ethereum DeFi, provided it can effectively address its scalability and interoperability challenges. Bitcoin’s unmatched security and widespread recognition as a store of value give it a strong foundation.

With the ability to support complex dApps and seamless cross-chain interactions, Bitcoin can attract a broader range of developers and users. If BTCFi can leverage its security and integrate the advanced smart contract functionalities, it could offer a compelling alternative to Ethereum DeFi, especially for users who prioritize security and stability in their financial transactions​.

YLR: Bitcoin mining locations tend to concentrate where economic, regulatory, and technological conditions are most favourable. While the halving might initially seem to favour established miners with the capital and infrastructure to manage reduced rewards, it could also lead to unexpected shifts in the mining landscape. As these major players potentially scale back operations to conserve resources during bearish periods, opportunities might arise for midsize and smaller mining collectives.

These groups could be less tied to the boom-bust cycles due to lower overheads and more flexible operation scales. Adding to the unpredictability are governments worldwide, which represent a significant wildcard. Should more countries follow El Salvador’s example in adopting Bitcoin in various capacities, it could radically alter the BTC mining terrain. It was just announced recently that the El Salvador government has already mined 474 BTC and this is a trend that we are likely to see increase as more geographic areas try to mimic their success.

This scenario could see the emergence of new mining centres, where a confluence of favourable conditions—such as supportive regulations, access to affordable energy, and technological advancements—aligns, contributing to a more decentralized and resilient mining ecosystem.
