在與Bitlayer的關鍵貢獻者Charlie Hu的獨家採訪中，討論了比特幣橋接技術的未來

In a exclusive interview with BeInCrypto, Charlie Hu, a key contributor to Bitlayer, delves into the future of Bitcoin bridging technologies, including the Finality Bridge and the BitVM Bridge.

在對Betlayer的關鍵貢獻者Charlie Hu的獨家採訪中，深入研究了比特幣橋接技術的未來，包括Finality Bridge和BitVM Bridge。

These groundbreaking solutions aim to solve Bitcoin’s limitations in scalability, programmability, and DeFi integration, offering a more secure and efficient way to move Bitcoin assets across blockchain ecosystems.

這些開創性的解決方案旨在解決比特幣在可伸縮性，可編程性和DEFI集成方面的限制，從而提供了一種更安全有效的方法，可以在區塊鏈生態系統中移動比特幣資產。

Hu elaborates on the technical differences between traditional multisig setups and the innovative trust-minimized approach offered by the BitVM Bridge. He also highlights how the Finality Bridge enables Bitcoin holders to engage in DeFi activities, ultimately contributing to the growth of the DeFi space and improving liquidity.

Hu詳細闡述了傳統的Multisig設置與BITVM Bridge提供的創新信任最小方法之間的技術差異。他還強調了最終橋樑如何使比特幣持有人從事Defi活動，最終為Defi空間的增長做出了貢獻並提高了流動性。

The Role of the Finality Bridge and BitVM Bridge

最終橋樑和BITVM橋的作用

The Finality Bridge and BitVM Bridge represent the next evolution in Bitcoin bridging technology. These solutions aim to enhance Bitcoin’s ability to interact with decentralized finance (DeFi) ecosystems, which has traditionally been a challenge due to Bitcoin’s lack of programmability.

最終橋樑和BITVM橋代表了比特幣橋接技術的下一個演變。這些解決方案旨在增強比特幣與分散財務（DEFI）生態系統互動的能力，由於比特幣缺乏可編程性，傳統上這是一個挑戰。

Charlie Hu explains that the BitVM Bridge is the third generation of Bitcoin bridging solution technology.

查理·胡（Charlie Hu）解釋說，BITVM橋是第三代比特幣橋接解決方案技術。

“The BVM bridge is the third-generation Bitcoin bridging solution technology. We have wrapped Bitcoin, which relies on an older multisig setup—a federation of signers where the majority must be honest. However, it’s clear that we can’t rely on wrapped Bitcoin as a long-term bridging solution. We need a new generation of technology that is more trust-minimized and doesn’t depend on the current multisig structure to bridge Bitcoin liquidity from Bitcoin Layer 1 (L1) to EVM (Ethereum Virtual Machine) or other programmable environments,” Hu said.

“ BVM橋是第三代比特幣橋接解決方案技術。我們包裹了比特幣，該比特幣依賴於較舊的Multisig設置，這是一個簽名人聯合會，大多數人必須是誠實的。但是，很明顯，我們不能依靠包裹的比特幣作為長期橋接解決方案。我們需要一種新一代的技術，該技術更具信任度最低，並且不取決於當前的多型結構，以將比特幣流動性從比特幣1（L1）（L1）橋接到EVM（以太坊虛擬機）或其他可編程環境。”

Previous systems, like wrapped Bitcoin, relied on older multisig setups, where a federation of signers needed to maintain honesty to ensure security. However, this structure has proven to be unreliable and exposes users to potential risks.

以前的系統，例如包裹的比特幣，都依賴於較舊的Multisig設置，在該設置中，簽名者需要保持誠實以確保安全性。但是，這種結構已被證明是不可靠的，並使用戶面臨潛在的風險。

“In contrast, the BitVM bridge is more trust-minimized. We only need to trust one signer to be honest, and that signer can unlock the funds through the two-way pegging mechanism,” Hu continues.

“相比之下，BITVM橋更加信任。我們只需要信任一個簽名人誠實，該簽名人可以通過雙向固定機制解鎖資金，”胡繼續說道。

This improvement reduces the potential for malicious actors to compromise the system, addressing vulnerabilities exposed by recent incidents like the Bybit hack. Unlike wrapped Bitcoin, which relied heavily on multisig setups, the BitVM Bridge uses Bitcoin scripts and two-way pegging mechanisms to ensure more secure and efficient transactions between Bitcoin Layer 1 (L1) and Ethereum Virtual Machine (EVM) environments.

這種改善減少了惡意參與者損害該系統的潛力，解決了諸如Bybit Hack之類的最近事件所經歷的漏洞。與包裝的比特幣不同，該比特幣嚴重依賴於Multisig設置，BITVM Bridge使用比特幣腳本和雙向固定機制來確保比特幣1（L1）和以太坊虛擬機（EVM）環境之間更安全有效的交易。

Enabling DeFi on Bitcoin

在比特幣上啟用Defi

The limitations of Bitcoin Layer 1 in enabling decentralized finance are well-known. Bitcoin L1 does not support smart contracts, meaning it cannot facilitate lending, automated market makers, decentralized exchanges, or any other DeFi activities. Bitcoin’s UTXO-based cash system is primarily designed for payments, but it struggles with scalability and versatility in more complex scenarios.

比特幣第1層在實現分散融資中的局限性是眾所周知的。比特幣L1不支持智能合約，這意味著它無法促進貸款，自動化的做市商，分散交流或任何其他Fefi活動。比特幣的基於UTXO的現金系統主要是為了付款而設計的，但是在更複雜的情況下，它在可擴展性和多功能性方面進行了鬥爭。

To address these issues, the Finality Bridge offers a solution by connecting Bitcoin to more programmable, trust-minimized environments, like Layer 2 solutions.

為了解決這些問題，最終橋通過將比特幣連接到更可編程，信任最小的環境（例如第2層解決方案）來提供解決方案。

“Without the bridge, you can’t really do DeFi. Bitcoin L1 doesn’t have smart contract capabilities or programmability. You can only make payments. To enable Bitcoin DeFi—where Bitcoin holders want to earn yield, engage in on-chain options, liquid staking, and other creative DeFi use cases—you need to bridge to a programmable, trust-minimized environment like a Layer 2 solution,” Hu explains.

“沒有橋樑，您就無法真正做過defi。比特幣L1沒有智能合同功能或可編程性。您只能付款。為了啟用比特幣Defi（比特幣持有人想要賺取收益率，參與鏈上的選擇，液體蒸發和其他創意的Defi用例），您需要橋接到可編程，信任最小的環境（如第二層解決方案），” Hu解釋說。

Bitcoin L1’s scalability is constrained by its ability to process only seven transactions per second (TPS), which results in network congestion. This can lead to high fees and failed transactions as users compete to pay for limited block space.

比特幣L1的可伸縮性受到僅處理每秒7次交易（TPS）的能力，從而導致網絡擁塞。隨著用戶競爭以支付有限的塊空間，這可能會導致高費用和失敗的交易。

“Many users experienced this during the 2023 ordinals mint,” Hu recalls. “People paid for gas fees, but their transactions failed because they paid too little compared to others who were paying higher fees. This led to a situation where everyone was fighting to pay higher fees, but in the end, they burned their Bitcoin and the transactions still failed.”

“許多用戶在2023年的典型造幣廠中都經歷了這一點，”胡回憶道。 “人們支付了汽油費，但是他們的交易失敗了，因為與支付更高費用的其他人相比，他們支付的費用太少了。這導致了每個人都在努力支付更高費用的情況，但最終，他們燒毀了比特幣，交易仍然失敗了。”

The Finality Bridge solves these problems by enabling Bitcoin to interact with Layer 2 solutions, thereby allowing Bitcoin holders to participate in DeFi activities and scale their transactions without the limitations of Bitcoin L1.

最終橋樑通過使比特幣與第2層解決方案進行交互來解決這些問題，從而允許比特幣持有人參與DEFI活動並擴展其交易而無需比特幣L1的局限性。

The Versatility and Future of the Finality Bridge

最終橋樑的多功能性和未來

One of the significant advantages of the BitVM Bridge is its ability to bridge Bitcoin assets to a wide range of ecosystems, including both EVM and non-EVM chains. Through its recent partnerships with chains such as Arbitrum, Plume, Base, Starknet, and Sonic, the BitVM Bridge is positioning itself to be an essential component in the future of cross-chain interoperability.

BITVM橋樑的重要優勢之一是它可以將比特幣資產橋接到各種生態系統（包括EVM和非EVM鏈）的能力。通過與仲裁，羽流，基礎，斯塔克網和聲波等連鎖店的伙伴關係，BITVM橋將自己定位為跨鏈互操作性的未來的重要組成部分。

Sonic, for example, uses Solana VM, which opens the door for Solana ecosystem integration, despite its indirect connection to Bitcoin.

例如，Sonic使用Solana VM，儘管與比特幣的間接連接，但它為Solana生態系統集成打開了大門。

“Our bridge is versatile, supporting both EVM and non-EVM chains, making it highly adaptable,” says Hu. “For example, Sonic (which uses Solana VM) connects us

Hu說：“我們的橋樑是通用的，支持EVM和非EVM鏈，使其具有高度適應性。” “例如，Sonic（使用Solana VM）連接我們
