Bitcoin Rollup Citrea 籌集了 1400 萬美元的 A 輪融資，透過 ZK 證明使 BTC 成為可編程資產

Citrea 表示，讓比特幣區塊鏈發揮更大效用的目標幾乎是生死存亡的重要目標之一。

Bitcoin project Citrea, which aims to expand the original cryptocurrency’s utility with zero-knowledge technology, said Thursday it raised $14 million in Series A funding.

比特幣計畫 Citrea 週四表示，其 A 輪融資籌集了 1,400 萬美元，該計畫旨在透過零知識技術擴展原始加密貨幣的實用性。

The investment was led by Peter Thiel’s Founders Fund and included contributions from angel investors Erik Voorhees and Balaji Srinivasan, according to an announcement shared with CoinDesk.

根據與 CoinDesk 分享的公告，這筆投資由 Peter Thiel 的創始人基金牽頭，天使投資人 Erik Voorhees 和 Balaji Srinivasan 也參與了投資。

Citrea, which raised $2.7 million of seed funding in a Galaxy-led round in February, uses the BitVM computing paradigm that is designed to allow Ethereum-style smart contracts on Bitcoin.

Citrea 在 2 月由 Galaxy 主導的一輪融資中籌集了 270 萬美元的種子資金，它使用 BitVM 運算範式，旨在允許在比特幣上使用以太坊式智慧合約。

"Citrea is an EVM-compatible layer, meaning all the applications on Ethereum can simply deploy on Citrea without having to change anything," Orkun Mahir Kılıç, CEO of Citrea builder Chainway Labs, told CoinDesk in an interview last month.

「Citrea 是EVM 相容層，這意味著以太坊上的所有應用程式都可以簡單地部署在Citrea 上，而無需進行任何更改，」Citrea 建構者Chainway Labs 的執行長Orkun Mahir Kılıç 在上個月的一次採訪中告訴CoinDesk。

The project aims to transform the Bitcoin blockchain into a venue for smart contracts by making bitcoin (BTC) a programmable asset through the use of zero-knowledge (ZK) technology.

該專案旨在透過使用零知識（ZK）技術使比特幣（BTC）成為可編程資產，從而將比特幣區塊鏈轉變為智慧合約的場所。

ZK technology allows data to be transferred securely between parties through the ability to demonstrate knowledge without actually revealing the data and without the prover and verifier interacting.

ZK 技術透過展示知識的能力，允許數據在各方之間安全地傳輸，而無需實際洩露數據，也無需證明者和驗證者互動。

"Citrea enhances the capabilities of Bitcoin blockspace with ZK technology and enables the Bitcoin network to support diverse on-chain applications and platforms," Citrea said.

Citrea 表示：“Citrea 透過 ZK 技術增強了比特幣區塊空間的功能，使比特幣網路能夠支援多樣化的鏈上應用和平台。”

The goal of allowing greater utility is one of "critical" importance, according to Citrea. While BTC has served well as a form of digital gold, it risks being sidelined by users relying on intermediaries and external networks to provide scalability, Citrea said.

Citrea 表示，實現更大效用的目標是「至關重要」的目標之一。 Citrea 表示，雖然 BTC 作為數位黃金的一種形式表現良好，但它面臨著被依賴中介機構和外部網路提供可擴展性的用戶邊緣化的風險。

Bitcoin is therefore being undermined by the absence of a "proper scalability solution," hindering its role in decentralized finance (DeFi), which means it "risks losing its relevance in DeFi and becoming obsolete as a network."

因此，比特幣因缺乏「適當的可擴展性解決方案」而受到損害，阻礙了其在去中心化金融（DeFi）中的作用，這意味著它「有失去在DeFi 中的相關性並作為網絡被淘汰的風險」。

The use of intermediaries to expand Bitcoin's utility is being explored by projects like layer-2 BOB, which aims to create bridges to other networks like Ethereum for the execution of transactions that are ultimately anchored on Bitcoin.

Layer-2 BOB 等計畫正在探索利用中介機構來擴展比特幣的效用，該計畫旨在建立與以太坊等其他網路的橋樑，以執行最終錨定在比特幣上的交易。
