sBTC 首次登陸 Stacks 主網，標誌著可編程比特幣的新時代

sBTC 旨在釋放比特幣 (BTC) 的流動性，是在 Stacks 於 8 月底啟動中本聰升級之後推出的。

Bitcoin (BTC)-related decentralized finance (DeFi) protocols are set to witness a surge in activity following the mainnet launch of a programmable 1:1 Bitcoin-backed asset, dubbed sBTC.

在主網推出可編程 1:1 比特幣支援資產（稱為 sBTC）後，與比特幣 (BTC) 相關的去中心化金融 (DeFi) 協議的活動將會激增。

Announced by Bitcoin L2 Labs, the core development team behind Stacks (CRYPTO:STX), on Monday, the launch of sBTC marks a major step toward building an on-chain Bitcoin economy.

Stacks（CRYPTO：STX）背後的核心開發團隊 Bitcoin L2 Labs 週一宣布，sBTC 的推出標誌著朝著建構鏈上比特幣經濟邁出的重要一步。

The development comes after the delivery of faster transactions and 100% Bitcoin finality to the Stacks network with the Nakamoto Upgrade in October.

這項進展是在 10 月透過 Nakamoto 升級向 Stacks 網路提供更快的交易和 100% 比特幣最終確定性之後實現的。

For the broader Bitcoin community, the launch of sBTC signals a new era of programmable Bitcoin, enabling the world’s most secure blockchain to participate actively in DeFi.

對於更廣泛的比特幣社群來說，sBTC 的推出標誌著可編程比特幣的新時代的到來，使世界上最安全的區塊鏈能夠積極參與 DeFi。

Designed to Unfold Broad DeFi Opportunities

旨在釋放廣泛的 DeFi 機會

The launch of sBTC follows Stacks initiating the Nakamoto Upgrade in late August, and it is designed to unlock Bitcoin (BTC) liquidity.

sBTC 的推出是在 Stacks 於 8 月底啟動中本聰升級之後推出的，旨在釋放比特幣 (BTC) 的流動性。

The development will enable BTC holders to access DeFi opportunities while retaining Bitcoin’s unmatched security principles.

這項進展將使 BTC 持有者能夠獲得 DeFi 機會，同時保留比特幣無與倫比的安全原則。

Specifically, users can engage in DeFi applications, such as lending and borrowing on protocols like Zest, decentralized exchanges (DEXs) like Bitflow and ALEX, or even AI-based tools like aiBTC.

具體來說，用戶可以參與 DeFi 應用，例如在 Zest 等協議上進行借貸，Bitflow 和 ALEX 等去中心化交易所（DEX），甚至 aiBTC 等基於人工智慧的工具。

“Unlike locking BTC in proof-of-stake systems, sBTC is fully expressive and enables an on-chain Bitcoin economy. It can power decentralized lending, DEXs, AI bots, and more while inheriting 100% Bitcoin hash power security,” said Muneeb Ali, Stacks founder, in a press release shared with BeInCrypto.

「與將 BTC 鎖定在權益證明系統中不同，sBTC 具有充分的表現力，可以實現鏈上比特幣經濟。它可以為去中心化借貸、DEX、人工智慧機器人等提供動力，同時繼承 100% 的比特幣算力安全性。

Key Features of sBTC: A Closer Look

sBTC 的主要特點：仔細觀察

Among the key features of sBTC is a 1:1 Bitcoin backing, where the pioneer crypto fully collateralizes each sBTC token.

sBTC 的主要特點之一是 1:1 的比特幣支持，先鋒加密貨幣完全抵押每個 sBTC 代幣。

Secondly, there is the institutional signer network, which reduces reliance on single entities, thereby enhancing trust.

其次，機構簽署者網路減少了對單一實體的依賴，從而增強了信任。

Additionally, sBTC has 100% Bitcoin finality, which means it is secured by Bitcoin hash power, ensuring strong security. Furthermore, the product has transparent, open-source code, which offers transparency and verifiability for developers and users.

此外，sBTC 具有 100% 比特幣最終確定性，這意味著它受到比特幣算力的保護，確保了強大的安全性。此外，該產品具有透明的開源程式碼，為開發人員和使用者提供透明度和可驗證性。

However, the current mainnet phase introduces deposit-only functionality, which is capped at 1,000 BTC.

然而，目前的主網階段引入了僅限存款功能，上限為 1,000 BTC。

Despite this limitation, the cap will provide initial liquidity for developers and enable further integrations with institutional custodians and ecosystem partners.

儘管有此限制，該上限仍將為開發者提供初始流動性，並實現與機構託管人和生態系統合作夥伴的進一步整合。

According to the press release, withdrawals will only become available in Q1 2025 as the system transitions toward a fully open, permissionless signer set.

根據新聞稿，隨著系統向完全開放、無需許可的簽署者集過渡，提款將在 2025 年第一季開放。

Depositors will also earn annual rewards of up to 5% in sBTC for holding the asset, presenting a unique yield opportunity for Bitcoin holders.

持有該資產的儲戶還將獲得高達 5% 的 sBTC 年度獎勵，這為比特幣持有者提供了獨特的收益機會。

Bringing Bitcoin Closer to DeFi Dominance

讓比特幣更接近 DeFi 的主導地位

Meanwhile, sBTC’s launch is poised to propel Bitcoin closer to Ethereum’s dominance in the DeFi space.

同時，sBTC 的推出有望推動比特幣進一步接近以太坊在 DeFi 領域的主導地位。

While Ethereum boasts a total value locked (TVL) approaching $80 billion, according to DefiLlama data, Bitcoin is fast approaching after flipping Binance Smart Chain (BSC).

根據 DefiLlama 的數據，雖然以太坊的總鎖定價值 (TVL) 接近 800 億美元，但比特幣在翻轉幣安智能鏈 (BSC) 後正在快速逼近。

The successful rollout of sBTC sets the foundation for a stronger Bitcoin Layer-2 ecosystem. The gradual lifting of the BTC cap, the introduction of withdrawals, and the transition toward a permissionless signer network could drive further adoption.

sBTC 的成功推出為更強大的比特幣 Layer-2 生態系統奠定了基礎。比特幣上限的逐步取消、提款的引入以及向無需許可的簽名者網路的過渡可能會推動進一步的採用。

With sBTC Bitcoin is no longer just a store of value but a versatile asset for decentralized applications (dApps).

有了 sBTC，比特幣不再只是一種價值儲存手段，而是一種去中心化應用程式 (dApp) 的多功能資產。

“With sBTC, Bitcoin becomes highly capable beyond a store of value, unlocking the full potential of BTC in decentralized applications,” Andre Serrano, Head of Product at Bitcoin L2 Labs, emphasized.

比特幣 L2 實驗室產品主管安德烈·塞拉諾 (Andre Serrano) 強調：“通過 sBTC，比特幣變得超越了價值存儲，從而釋放了 BTC 在去中心化應用中的全部潛力。”

The development also enhances opportunities for DeFi builders. Zest Protocol, for instance, allows users to earn additional rewards while holding sBTC.

這一發展也增加了 DeFi 建造者的機會。例如，Zest Protocol 允許用戶在持有 sBTC 的同時獲得額外獎勵。

“Earn more Zest points. Just holding sBTC gives users a 5% yield, thanks to the Stacks rewards program. With Zest, users can supercharge their yield with sBTC,” the platform noted.

「賺取更多熱情積分。由於 Stacks 獎勵計劃，僅持有 sBTC 讓用戶獲得 5% 的收益。借助 Zest，用戶可以透過 sBTC 大幅提高收益。

As Bitcoin capital flows into DeFi protocols, builders, developers, and users will benefit from enhanced liquidity and innovative financial tools.

隨著比特幣資本流入 DeFi 協議，建構者、開發者和用戶將受益於增強的流動性和創新的金融工具。
