Bitcoin L2s help crypto miners in Asia supplement income with staking

One crypto narrative that has garnered significant traction across the Asian technological landscape is the rise of Bitcoin layer-2 (L2) solutions. 

Chinese miners are still an important part of the Bitcoin BTCUSD mining ecosystem — reportedly accounting for over 50% of the network’s hashrate — the rise of these solutions seems to be bolstered by miners seeking to create alternative revenue streams for themselves, especially in the wake of the recent Bitcoin halving.

The Bitcoin halving, a programmed event that reduces BTC mining rewards by half, has traditionally been challenging for miners. The most recent halving, which concluded on April 19, reduced the digital asset’s reward ratio from 6.25 BTC to 3.125 BTC, making it tougher for miners to stay profitable.

However, the rapid emergence of Bitcoin L2 technologies seems to be offering a lifeline to these critical network participants. Robbie Liu, head of Asia at blockchain protocol Polyhedra Network, told Cointelegraph:

Liu elaborated on the dominance of Asian projects within the Bitcoin L2 space, highlighting that many of the region’s L2 offerings — such as Singapore-based Bitlayer — are leaders in total value locked (TVL). 

“We are also witnessing the emergence of some notable Western projects like Stacks, BOB and Anduro,” he added.

Despite numerous regulatory challenges and periodic crackdowns, Chinese miners have shown remarkable resilience and adaptability. Bitcoin L2s have further helped them stay profitable by providing supplemental income streams through staking. 

Staking, restaking and capital inflows

One of the most significant developments in the Bitcoin L2 space over the past year or so has been the introduction of various staking and restaking mechanisms, which allow Bitcoin holders (including miners) to earn additional income streams without selling their holdings.

Yongjin Kim, CEO of crypto futures exchange Flipster, told Cointelegraph that projects with staking are opening up new possibilities for capital efficiency, citing protocols like Babylon as an example.

He said that the platform allows stakers to earn rewards in a trustless and self-custodial manner. Furthermore, on the importance of utilizing BTC’s dormant capital, Kim went on to say:

The potential to extend Bitcoin’s utility within areas such as RWAs has not gone unnoticed by investors. Recently, there has been a significant surge in capital flowing into the ecosystem, accelerating infrastructure development across Asia.

This influx of funding can attract more developers and entrepreneurs to the space while fueling further innovations. Alex Zuo, vice president of Singapore-based crypto asset management platform Cobo, told Cointelegraph:

In his view, this expansion is crucial for Bitcoin’s long-term viability as a platform for diverse financial applications. Zuo highlighted the Bitcoin L2 Merlin Chain, stating that the project was able to amass over $3.5 billion in TVL within just 30 days of its mainnet launch back in February. 

Zuo believes that the success of projects like these can potentially lay the foundational proof-of-concept for future L2s.

Innovations galore, but work still needs to be done

Despite the enthusiasm surrounding Bitcoin’s L2 ecosystem, challenges still remain, particularly in terms of BTC’s existing asset and security management protocols.

The complexity of these systems and the high stakes involved in managing large amounts of Bitcoin create unique security considerations.

Alvin Kan, chief operating officer for Bitget Wallet, told Cointelegraph that these challenges arise primarily due to the inherent complexity and risks of managing decentralized systems.

He pointed to projects like the Lightning Network, Rootstock and Liquid Network as examples of initiatives addressing these issues through various approaches, from offchain transactions to smart contract platforms and federated sidechains.

The Lightning Network, for example, focuses on improving scalability and reducing transaction fees through offchain transactions. It uses a network of bi-directional payment channels, allowing users to transact quickly and efficiently.

This approach is particularly promising for enabling micropayments and other high-frequency, low-value transactions that would be impractical on the main Bitcoin blockchain.

Rootstock brings Ethereum-compatible smart contracts to the Bitcoin network, opening up new possibilities for decentralized applications and complex financial instruments built on top of Bitcoin. The platform emphasizes security through contract audits and formal verification, addressing one of the key concerns of the L2 space.

The Liquid Network, developed by Blockstream, takes yet another approach. As a federated sidechain solution, it enhances privacy and speeds up transactions, addressing liquidity management and inter-exchange settlement issues. This could be particularly valuable for institutional investors and large-scale Bitcoin holders looking for more efficient ways to manage their assets.

Adoption of Bitcoin L2s to grow

As more developers and projects in Asia continue to focus on Bitcoin L2s, the ecosystem seems poised for significant growth and evolution.

Kan predicts several trends that can shape the future of this space over the coming years, namely the widespread adoption of solutions like the Lightning Network, especially among countries with high remittance inflows, and substantial growth in decentralized finance applications built on Bitcoin L2 platforms.

Another trend is the expansion of cross-chain interoperability solutions. As the blockchain ecosystem becomes increasingly diverse, the ability to move assets seamlessly between different networks will become more crucial. Bitcoin L2s that can facilitate this interoperability could play a key role in the broader blockchain ecosystem.

The rise of L2s in Asia seems to be part of a broader trend, with countries such as Vietnam, Thailand, Singapore and Hong Kong concurrently positioning themselves as crypto-friendly jurisdictions.

These countries’ crypto-friendly regulations aim to attract high-quality talent and capital from around the world while providing a supportive ecosystem for projects to flourish.

Looking ahead, China’s dominance within the BTC mining realm seems to be setting the stage for Asia to lead the charge in Bitcoin L2 innovation.

As miners adapt to the realities of a post-halving world and developers flock to build on these new platforms, they have the potential to transform not only the Bitcoin network but also the broader financial landscape across Asia.
