Layer-2 Networks Essential for Bitcoin Functionality

Heightened Bitcoin (BTC) network activity has resulted in prolonged processing durations and increased transaction fees.

This has prompted a significant rise in Bitcoin layer-2 (L2) development. Bitcoin L2 solutions aim to enhance Bitcoin’s scalability, lower transaction expenses, and introduce virtual machine programmability to the network.

For example, the Bitcoin L2 Lightning Network was created to facilitate BTC transfers more swiftly than on the Layer-1 network. Layer-2 solutions have also contributed to the emergence of decentralized finance (DeFi) on the Bitcoin network.

A recent report from crypto exchange Bybit indicates that there are over 74 Bitcoin L2 solutions, the majority of which have been developed in the last two quarters. The report highlights that Bitcoin L2s include sidechains, rollups, and state channels.

Bitcoin Usability Relies on L2s

Rena Shah, COO of Trust Machines – a collective of committed Bitcoin developers – informed Cryptonews that Bitcoin usability has increasingly depended on Layer-2 infrastructure.

“For Bitcoin Builders, this seemed evident, but we are finally witnessing it unfold in real-time,” Shah stated. “Most transactions can be settled more quickly and affordably on the L2, while the Bitcoin L1 concentrates on high-value settlements.”

Shah further noted that a vast amount of potential can be unlocked for Bitcoin through L2 solutions.

“Bitcoin as a decentralized foundational layer for applications is finally becoming a reality,” she remarked.

Bitcoin L2s Exhibit Significant Growth

Daniel Fogg, CEO of Rootstock – a well-established Bitcoin sidechain – shared with Cryptonews that Rootstock has experienced record transaction volumes in the past three months.

“According to block explorer data, there have been over 13 million transactions to date on the Rootstock network, with more than 670,000 transactions occurring in the last three months alone,” Fogg stated.

Fogg also mentioned that Rootstock has integrated several decentralized applications (dApps) and wallet functionalities.

“In just the last three months, over 25 dApps and protocols have been incorporated into the Rootstock ecosystem, providing users with new avenues to access, build, and expand on Rootstock,” he noted.

For instance, the well-known decentralized exchange (DEX) SushiSwap launched on Rootstock last month. As per Token Terminal, SushiSwap boasts over 438,000 active monthly users and 113,000 active weekly users.

“The integration enables Sushi users to trade and provide liquidity on Rootstock, utilizing Bitcoin’s security and decentralization,” a SushiSwap blog post highlighted.

This also allows Sushi users to leverage Bitcoin assets for DeFi purposes.

L2s Facilitate Liquidity and DeFi Applications

Jeff Yin, Founder of the L2 solution MerlinChain, believes that enhancing liquidity across Bitcoin L2s will further encourage individuals to engage in trading and other DeFi activities on Bitcoin.

Yin informed Cryptonews that MerlinChain has commenced building significant liquidity across its network.

“Currently, the Bitmap and Rune token liquidity on the Merlin DEX is nearing $10 million,” Yin stated. “We aim to swiftly elevate this to $30 million, $50 million, or even $100 million. This is a crucial initial step as improved liquidity will promote participation from users of other chains.”

The BTC L2 narrative mindshare is growing.

Fast & cheap transactions on Bitcoin, the hardest crypto asset, are an attractive narrative.

But the complexities of building a REAL decentralized L2 that inherits the security of BTC are significant.

Karan Bharadwaj, CEO of the L2 staking network Arithmic, informed Cryptonews that Arithmic also aims to unlock liquidity across the Bitcoin network. He explained that Arithmic achieves this through native restaking, which integrates both Bitcoin and Ethereum L2s.

“This consolidates liquidity, streamlines the bridging process, and enables users to maximize opportunities across platforms, delivering a seamless and efficient experience,” Bharadwaj stated.

Challenges Linked to Multiple L2s

Bharadwaj added that native restaking is becoming essential with the increasing number of Bitcoin L2s today.

“The primary challenges currently confronting Bitcoin L2s include liquidity fragmentation, complexities in bridge usage, and scalability issues amid rising transaction volumes,” he remarked.

Bharadwaj believes that these challenges can be addressed by concentrating on interoperability standards to unify liquidity across Bitcoin and Ethereum L2s.

“Engaging and nurturing a supportive community around L2 developments will also be crucial in overcoming these challenges and promoting broader adoption in the crypto ecosystem,” Bharadwaj added.

Justin Wolfskehl, Community Core Team Member of The Bitcoin Name System (BNS) – a platform that enables users to register and manage BNS domain names – told Cryptonews that he perceives the greatest challenge facing L2s is acceptance.

“Everyone desires to use Bitcoin more quickly and affordably, but it remains uncertain which solution will gain mainstream acceptance,” Wolfskehl stated.

Indeed, while it is noteworthy that Bitcoin L2s are increasing, only a limited number of these solutions are likely to be widely adopted.

“As the COO of a company developing the largest ecosystem of Bitcoin applications to maximize the value of the Bitcoin network, we are pleased to witness the emergence of so many L2s,” Shah remarked. “Hundreds will be created, but only a select few will achieve the mass adoption and capital necessary to succeed.”

Bitcoin L2s Continue to Flourish

Despite the challenges, industry experts remain optimistic that Bitcoin L2s will persist in evolving and maturing.

Recently, the interoperability protocol ZKM announced plans to introduce a Bitcoin L2 solution named “GOAT Network.” According to a press release, the network will launch with a decentralized sequencer model. Sequencer node operators will assist in securing the network while earning a yield on their Bitcoin.

Although GOAT Network claims to be the first genuinely decentralized L2, achieving decentralization remains a challenge for Bitcoin L2s.

“The more decentralized the solution is, the more difficult it is to construct,” Wolfskehl pointed out. “The less decentralized it is, the easier. However, most users indicate that they place a high value on decentralization, making it challenging to find a balance.”

In addition to the launch of GOAT, crypto startup Hamilton announced tokenized United States Treasury bonds on Bitcoin L2 blockchains. Hamilton U.S. T-Bills (HUST) will soon be accessible on Stacks, Core, and BoB (Build on Bitcoin) L2s.

“BTC remains the king of all assets, and everyone aims to deploy it because it solidifies an on-chain world,” Shah stated.

Wolfskehl added that upcoming updates on the Stacks L2 solution will contribute to advancing the ecosystem.

“Stacks has an upgrade called ‘Nakamoto’ that is scheduled for release in August,” he said. “Transactions on Stacks are linked to Bitcoin blocks, meaning each transaction on Stacks takes approximately 10 minutes. The Nakamoto upgrade promises to reduce block times to seconds while still ensuring Bitcoin finality, meaning transactions are as secure as Bitcoin itself.”

According to Wolfskehl, the Nakamoto upgrade will make dApp interactions, such as token swaps or domain name registrations, comparable to experiences on Ethereum or Solana.

“I believe the Nakamoto upgrade will be significant for Stacks, BNS, and the entire BTC L2 ecosystem,” Wolfskehl remarked.
