比特幣的門戶網站宣布將其原子交換擴展到Solana區塊鏈

無用的十字鏈基礎設施比特幣的門戶網站宣布將其原子交換擴展到Solana區塊鏈，以實現無信任的BTC-SOL交換。

Portal to Bitcoin, a bridgeless crosschain infrastructure, announces the expansion of its atomic swaps to the Solana blockchain to enable trustless BTC-SOL swaps.

無用的十字鏈基礎設施比特幣的門戶網站宣布將其原子交換擴展到Solana區塊鏈，以實現無信任的BTC-SOL交換。

No other network comes close to Bitcoin when it comes to robustness and security. However, it has a catch: The massive liquidity circulating within the Bitcoin blockchain stays largely isolated from the rest of decentralized finance (DeFi) ecosystems due to technical limitations.

在魯棒性和安全性方面，沒有其他網絡接近比特幣。但是，它有一個捕捉：由於技術局限性，比特幣區塊鏈內的大量流動性在很大程度上與分散的金融（DEFI）生態系統隔絕。

As Bitcoin remains the most secure and valuable digital asset, its liquidity has often been difficult to tap for fast-growing ecosystems like Solana and Ethereum. Different blockchains usually require costly or complex bridging methods — involving custodial risk or wrapped assets — to access Bitcoin’s liquidity.

由於比特幣仍然是最安全，最有價值的數字資產，因此對於Solana和Ethereum等快速增長的生態系統，其流動性通常很難利用。不同的區塊鏈通常需要昂貴或複雜的橋接方法（涉及託管風險或包裝資產）才能獲得比特幣的流動性。

Breaking down blockchain barriers

打破區塊鏈障礙

Portal to Bitcoin is a bridgeless, non-custodial, crosschain infrastructure that offers an innovative solution to the limitations that have kept Bitcoin’s liquidity locked away from broader DeFi applications. Following a successful rollout of trustless Bitcoin-to-Ethereum swaps in its testnet, Portal to Bitcoin has announced that it will expand its swap services to Solana.

Bitcoin的門戶網站是一種無用的，無限制的，交叉鏈基礎架構，為使比特幣的流動性鎖定在更廣泛的DEFI應用程序中的局限性提供了創新的解決方案。在其測試網中成功推出了無信任的比特幣到埃里姆交換之後，對比特幣的Portal宣布，它將擴大其掉期服務對Solana。

Once rolled out, the Portal Testnet V2 will enable users to swap Bitcoin (BTC) into Solana (SOL) and Solana Program Library (SPL) assets without turning to centralized intermediaries, wrapped assets or traditional bridging solutions.

一旦推出，Portal TestNet V2將使用戶能夠將比特幣（BTC）交換為Solana（Sol）和Solana Program庫（SPL）資產（SPL）資產，而無需轉向集中式中介機構，包裝資產或傳統的橋接解決方案。

Interoperability enables Bitcoin to be more than a store of value, enriching its role in DeFi, boosting adoption, and spurring innovation.The problem? Trusting middlemen to shuttle BTC across blockchains.This is where Portal steps in! 🧵👇 pic.twitter.com/1rgaJN5Ozq

互操作性使比特幣不僅僅是價值存儲，豐富了其在Defi，提高采用和刺激創新的作用。問題？信任中間商跨越區塊鏈穿梭BTC。這是門戶網站介入的地方！ 🧵👇pic.twitter.com/1rgajn5ozq

Unlike many crosschain approaches that add complexity or impose custody risks, Portal’s new integration maintains full user control throughout the transaction process. This means holders never relinquish ownership of their BTC while swapping into Solana’s high-throughput ecosystem, which boasts near-instant transaction finality and notably low fees.

與許多增加複雜性或施加監護風險的十字鏈方法不同，Portal的新集成在整個交易過程中保持了完整的用戶控制。這意味著持有人在交換Solana的高通量生態系統時永遠不會放棄其BTC的所有權，該生態系統具有近乎固有的交易終結性和尤其是低費用。

In practical terms, Bitcoin holders can soon engage directly with popular Solana-based decentralized exchanges (DEXs), lending protocols, memecoins and even NFT marketplaces, expanding the range of potential use cases for their BTC, while being able to safely swap back right into native BTC without taking any bridge, smart contract or custody risks.

實際上，比特幣持有人很快就可以直接與流行的基於Solana的分散交易所（DEX），貸款協議，成員甚至NFT市場直接互動，從而擴大了其BTC的潛在用例，同時能夠在不採取任何橋樑，智能合同或監護權的情況下將其安全地交換為本機BTC。

Integrating Bitcoin to Solana: Why it matters

將比特幣集成到Solana：為什麼重要

Solana’s appeal lies in its ability to process thousands of transactions per second with minimal cost. By tapping into Bitcoin’s liquidity pool, Portal’s integration has the potential to drive greater DeFi adoption on Solana.

Solana的吸引力在於其每秒以最低成本處理數千筆交易的能力。通過利用比特幣的流動性池，門戶網站的集成有可能推動對Solana上的更大採用。

Developers and liquidity providers stand to benefit from broader user participation, while retail and institutional investors gain a more straightforward avenue to diversify into the Solana ecosystem. At the same time, it removes the need for offchain custodial services or crosschain bridges, vaults, multi-sigs and other custodial solutions, all of which have proven vulnerable in the past.

開發商和流動性提供商將從更廣泛的用戶參與中受益，而零售和機構投資者則獲得了更直接的途徑，以使Solana生態系統多樣化。同時，它消除了對離鏈託管服務或交叉鏈橋，保險庫，多核心和其他託管解決方案的需求，所有這些解決方案過去曾證明了過去的脆弱性。

Trustless BTC-SOL swaps via proprietary technology

通過專有技術的無信任的BTC-SOL交換

From a technical standpoint, Portal leverages its proprietary BitScaler technology to facilitate atomic swaps directly between BTC and SOL. Unlike many crosschain platforms that rely on multisignature bridges or wrapped assets, BitScaler leverages the implementation of a Channel Factory, modified with other advanced features such as Taproot, policy language, multiparty-HTLCs and others to make a native AMM possible on Bitcoin.

從技術的角度來看，門戶網站利用其專有的Bitscaler技術來促進直接在BTC和SOL之間的原子交換。與許多依靠多符號橋樑或包裝資產的十字鏈平台不同，Bitscaler利用了通過其他高級功能（例如Taproot，Policy Langue，Multiparty-HTLCS和其他）進行修改的頻道工廠的實現，以使比特幣上的本機AMM成為可能。

Operating as a true crosschain state channel/payment channel scaling framework built on Bitcoin, BitScaler allows multiple transactions to be processed efficiently without modifying Bitcoin’s base protocol.

BITSCALER作為建立在比特幣上的真正的交叉鏈狀態通道/支付通道縮放框架，允許在不修改比特幣的基本協議的情況下有效地處理多個交易。

BitScaler’s modified channel factory design enables multiple peer-to-peer channels from a single onchain transaction, further reducing onchain fees compared to Lightning while keeping LP funds and traders’ funds safe and non-custodial. This hub-and-spoke design also helps mitigate liquidity fragmentation by pooling resources in a shared channel system, thereby reducing transaction costs and increasing throughput for DeFi users across multiple networks.

BITSCALER修改的頻道工廠設計可以通過單個OnChain交易實現多個點對點渠道，與Lightning相比，還可以進一步降低OnChain費用，同時保持LP資金和交易者的資金安全且非監測。這種樞紐和輻條設計還可以通過在共享的渠道系統中匯總資源來減輕流動性分散，從而降低了交易成本並增加了多個網絡的Defi用戶的吞吐量。

“With BitScaler, we’ve not only solved the long-standing challenges of Bitcoin scaling but have also opened up new possibilities for the entire ecosystem. This is the future of decentralized finance on Bitcoin,” said Chandra Duggirala, CEO of Tides.Network, Inc., the core developer of Portal to Bitcoin.

“有了BITSCALER，我們不僅解決了比特幣縮放的長期挑戰，而且還為整個生態系統開闢了新的可能性。這是對比特幣分權財務的未來。”

Security without compromise

沒有妥協的安全性

Portal’s methodology prioritizes decentralization and user control. Rather than relying on a governance token for security, the platform focuses on trustless, policy-based transaction scripts designed to uphold Bitcoin’s core principles.

門戶網站的方法優先考慮權力下放和用戶控制。該平台不依靠治理令牌來進行安全，而是專注於旨在維護比特幣核心原則的基於政策的交易腳本。

In addition, Portal employs Merkle tree synchronization and Partially Signed Bitcoin Transactions (PSBTs) that carry extra metadata, ensuring all parties remain aligned throughout the process. By removing custodial intermediaries and maintaining end-user autonomy, Portal addresses many pitfalls observed in past crosschain protocols that introduced unnecessary vulnerabilities.

此外，門戶網站還採用默克爾樹的同步和部分簽名的比特幣交易（PSBT），這些交易（PSBT）攜帶額外的元數據，確保所有各方在整個過程中保持對齊。通過刪除保管中介機構並保持最終用戶自治，門戶網站解決了在過去引入不必要漏洞的過去的交叉鏈協議中觀察到的許多陷阱。

Implications for broader DeFi and NFT markets

對更廣泛的Defi和NFT市場的影響

For Bitcoin holders, Portal’s integration promises speedier transactions, lower costs and access to a growing suite of Solana-based applications. They can trade BTC directly on Solana-native decentralized exchanges, NFT marketplaces and lending protocols without relying on centralized platforms. This ease of movement could significantly expand liquidity across both

對於比特幣持有者，Portal的集成承諾將較快的交易，較低的成本以及不斷增長的基於Solana的應用程序的訪問權限。他們可以直接在索拉納本地分散交易所，NFT市場和貸款協議上直接交易BTC，而無需依靠集中式平台。這種輕鬆的移動可以大大擴大兩者的流動性
