Bitcoin Layer 2: Lessons from Ethereum – A Comedy of Errors Awaits!

by

Bitcoin Layer 2s: Ah, the grand race to elevate the venerable Bitcoin into the splendiferous realm of DeFi! Our courageous contenders like Bitlayer are valiantly attempting to bestow upon Bitcoin the enchanting prowess of Ethereum-like capabilities. 💪

Yet, despite holding the impressive title of the largest cryptocurrency by market cap, Bitcoin finds itself entangled in the quagmire of inefficiency. Almost 99% of its glittering treasure remains locked away in digital vaults, yearning for the day it can frolic in the lively world of real-world applications. Alas, this task resembles attempting to teach a cat to fetch. 🐱

Meanwhile, Ethereum, with its well-honed fiendish cleverness, has been tirelessly developing Layer 2 solutions, gaining an early lead in this digital relay race. This spirited endeavor has fostered a dazzling ecosystem filled with innovations, hard-won wisdom, and cautionary tales from which our Bitcoin Layer 2s may whimsically benefit.

This delightful discourse features the eloquent musings of Bitlayer Co-Founder Kevin He, who shares invaluable insights for the builders who dare to scale the mighty Bitcoin.

As we craft our exquisite Bitcoin Layer 2 solutions, it is most prudent to glean the vital lessons bestowed upon us by Ethereum’s whimsical escapades into Layer 2.

Before joining the ranks of Bitlayer, Kevin was busy adornments such as Vice President at New Huo Tech, Senior Technical Director at Huobi, and Chief Scientist at YOUChain. Someone give this man a crown! 👑

Bitcoin Layer 2 Must Focus on Onchain Verification

From Stacks to Rootstock and the bold newcomers como Bitlayer and Botanix, the Bitcoin Layer 2 landscape is blossoming like a spring garden! 🌸 These endeavors strive to inject programmability into our cherished Bitcoin but must confront a lingering query: What pearls of wisdom can be harvested from Ethereum’s juicy Layer 2 tales?

Kevin elucidates the pressing matters at hand:

First, we find that rollups are the charming courtiers of the scaling court, managing to maintain a delicate equilibrium between scalability and security, all while holding fast to Bitcoin’s impressive trust assumptions.

However, dear builders, it stands to reason that the prioritization of onchain verification is non-negotiable. This allows for proofs or disputes to be settled directly on Bitcoin’s majestic base chain, minimizing reliance on the dubious whims of off-chain actors. Let us safeguard our decentralization! 🛡️

In the grand theater of Bitcoin, the engine of Spot BTC ETFs and their burgeoning alliance with traditional institutions has sparked new confidence. 📈 In the past year, Bitcoin’s value has tickled upwards by about 18%, playfully flirting with the $100,000 mark, before settling around a much more reasonable $81,575 as Trump Tariffs take a scenic detour.

Second—to add a pinch of spice to our tale—data availability (DA) is undoubtedly crucial for our beloved rollups, but Bitcoin’s ecosystem should graciously adopt adaptable solutions rather than enforcing one-size-fits-all designs. Think of it as a splendid buffet rather than a meager three-course meal. 🍽️

Embracing Bitcoin’s wonderfully community-driven spirit encourages delightful experimentation. By treating DA as a nimble and flexible component, Bitcoin Layer 2s can satisfy a variety of appetites, all while remaining true to our minimalist ideals.

In short, dear connoisseurs, anchor our foundations on trust-minimized onchain verification while letting modularity for DA joyfully frolic. Our hearts beat in sync with Bitcoin’s core tenets: decentralized, secure, and happily resistant to censorship!

On a related note, the wise sages over at Rootstock recently proclaimed plans to unveil a Software Development Kit, inviting eager developers to embark on their own Bitcoin Layer 2 odyssey.

Bitcoin didn’t need to change. It needed a layer to grow on.

User Experience Is Everything

Our scholarly friends in Ethereum L2s—Arbitrum, Optimism, and the merry band of others—discovered early that making users adopt new technology merely because it is speedier or cheaper is akin to trying to make a cat swim. Users crave an experience without friction akin to butter gliding on warm toast! 🥖

With their gleaming standards in user experience—swift transactions and seamless wallet interfaces—Bitcoin L2s must roll up their sleeves and aim to keep pace. Here, Kevin divulges the secrets to achieving this:

Bitcoin Layer 2s must skillfully balance enhancements in user experience while preserving the sanctity of protocol purity by adopting a subtle, layered architecture—comprised of Layer 1, Layer 2, and the tantalizing Unified UX Layer.

In the enchanting world of Layer 2 UX fragmentation, interoperability is not just a wish; it is our inevitable future! Bitcoin’s L2s should welcome the utopia of multichain interactions while deftly sidestepping forced protocol changes for the sake of convenience. Rather, let our user experience evolve organically through delightful tools like universal wallets.

Are we not in an age where managing multiple bank accounts through sleek apps is the norm? Let us embrace the future that allows decentralization and convenience to waltz together! 💃

Since the dawn of 2021, the kingdom of Bitcoin Layer 2 solutions has expanded with joy, growing from a mere 10 projects into a blossoming garden of 75—more than sevenfold! According to astute forecasts, by the year 2030, over $47 billion worth of BTC may gracefully waltz onto the Layer 2 catwalks.

Is Bitcoin DeFi The Future?

According to the scribes of Binance Research, our beloved Bitcoin DeFi (BTCFi) has rapidly ascended to one of the swiftest-growing sectors. With dApps blossoming like flowers in spring, it now competes gracefully among the top three DeFi ecosystems, boasting a current Total Value Locked (TVL) of a dazzling US$8.6B.

Kevin muses, “Bitcoin Layer 2s can catalyze a liquidity flywheel, but with a distinct driver: migrating value from off-chain (e.g., centralized exchanges, custodial services) to on-chain Bitcoin-native ecosystems.” 🌀

Essentially, the key to this lively dance will be a confluence of elements: the BitVM bridge, High-Performance L2s, and Native Yield Opportunities!

Enter the BitVM Bridge, ingeniously crafted and maintained by the capable hands at Bitlayer. It promises to be a trust-minimized protocol, effortlessly bridging Bitcoin with an array of blockchain ecosystems, including our esteemed Ethereum and other EVM-compatible realms.

This marvelous bridge facilitates the seamless infusion of Bitcoin’s liquidity into the whimsical world of decentralized finance (DeFi), much to the delight of those who partner with notable players like Arbitrum, Statknet, Base, SonicSVM, and Plume Network.

The enchanting flywheel shall commence as users migrate their BTC from custodial platforms into the fair arms of L2s for DeFi access. This, in turn, will attract developers galore to conjure tools, which will summon forth even greater liquidity.

Thus, we labor tirelessly on developing the BitVM Bridge, facilitating the seamless transition of Bitcoin into our sprawling Bitlayer ecosystem, enabling its integration into BTCFi, our burgeoning decentralized financial infrastructure.

Final Lesson for Developing Bitcoin Layer 2s

Thus, the fancies of our romantic tale instruct us that Bitcoin L2s may glean numerous lessons from Ethereum’s escapades fraught with peril—security breaches, bridge calamities—but amidst these myriad lessons, one final sentiment resonates:

Bitcoin’s crowning glory lies within its community’s steadfast commitment to security. Bitcoin Layer 2s can evade Ethereum’s security snafus by adopting a proactive, Bitcoin-native defense mechanism—prioritizing robustness over the quagmire of hastily amassed features.
