比特币的门户网站宣布将其原子交换扩展到Solana区块链

无用的十字链基础设施比特币的门户网站宣布将其原子交换扩展到Solana区块链，以实现无信任的BTC-SOL交换。

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

无用的十字链基础设施比特币的门户网站宣布将其原子交换扩展到Solana区块链，以实现无信任的BTC-SOL交换。

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.

在鲁棒性和安全性方面，没有其他网络接近比特币。但是，它有一个捕捉：由于技术局限性，比特币区块链内的大量流动性在很大程度上与分散的金融（DEFI）生态系统隔绝。

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.

由于比特币仍然是最安全，最有价值的数字资产，因此对于Solana和Ethereum等快速增长的生态系统，其流动性通常很难利用。不同的区块链通常需要昂贵或复杂的桥接方法（涉及托管风险或包装资产）才能获得比特币的流动性。

Breaking down blockchain barriers

打破区块链障碍

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的门户网站是一种无用的，无限制的，交叉链基础架构，为使比特币的流动性锁定在更广泛的DEFI应用程序中的局限性提供了创新的解决方案。在其测试网中成功推出了无信任的比特币到埃里姆交换之后，对比特币的Portal宣布，它将扩大其掉期服务对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将使用户能够将比特币（BTC）交换为Solana（Sol）和Solana Program库（SPL）资产（SPL）资产，而无需转向集中式中介机构，包装资产或传统的桥接解决方案。

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

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.

与许多增加复杂性或施加监护风险的十字链方法不同，Portal的新集成在整个交易过程中保持了完整的用户控制。这意味着持有人在交换Solana的高通量生态系统时永远不会放弃其BTC的所有权，该生态系统具有近乎固有的交易终结性和尤其是低费用。

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.

实际上，比特币持有人很快就可以直接与流行的基于Solana的分散交易所（DEX），贷款协议，成员甚至NFT市场直接互动，从而扩大了其BTC的潜在用例，同时能够在不采取任何桥梁，智能合同或监护权的情况下将其安全地交换为本机BTC。

Integrating Bitcoin to Solana: Why it matters

将比特币集成到Solana：为什么重要

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的吸引力在于其每秒以最低成本处理数千笔交易的能力。通过利用比特币的流动性池，门户网站的集成有可能推动对Solana上的更大采用。

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.

开发商和流动性提供商将从更广泛的用户参与中受益，而零售和机构投资者则获得了更直接的途径，以使Solana生态系统多样化。同时，它消除了对离链托管服务或交叉链桥，保险库，多核心和其他托管解决方案的需求，所有这些解决方案过去曾证明了过去的脆弱性。

Trustless BTC-SOL swaps via proprietary technology

通过专有技术的无信任的BTC-SOL交换

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.

从技术的角度来看，门户网站利用其专有的Bitscaler技术来促进直接在BTC和SOL之间的原子交换。与许多依靠多符号桥梁或包装资产的十字链平台不同，Bitscaler利用了通过其他高级功能（例如Taproot，Policy Langue，Multiparty-HTLCS和其他）进行修改的频道工厂的实现，以使比特币上的本机AMM成为可能。

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作为建立在比特币上的真正的交叉链状态通道/支付通道缩放框架，允许在不修改比特币的基本协议的情况下有效地处理多个交易。

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修改的频道工厂设计可以通过单个OnChain交易实现多个点对点渠道，与Lightning相比，还可以进一步降低OnChain费用，同时保持LP资金和交易者的资金安全且非监测。这种枢纽和辐条设计还可以通过在共享的渠道系统中汇总资源来减轻流动性分散，从而降低了交易成本并增加了多个网络的Defi用户的吞吐量。

“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，我们不仅解决了比特币缩放的长期挑战，而且还为整个生态系统开辟了新的可能性。这是对比特币分权财务的未来。”

Security without compromise

没有妥协的安全性

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.

门户网站的方法优先考虑权力下放和用户控制。该平台不依靠治理令牌来进行安全，而是专注于旨在维护比特币核心原则的基于政策的交易脚本。

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，门户网站还采用默克尔树的同步和部分签名的比特币交易（PSBT），这些交易（PSBT）携带额外的元数据，确保所有各方在整个过程中保持对齐。通过删除保管中介机构并保持最终用户自治，门户网站解决了在过去引入不必要漏洞的过去的交叉链协议中观察到的许多陷阱。

Implications for broader DeFi and NFT markets

对更广泛的Defi和NFT市场的影响

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

对于比特币持有者，Portal的集成承诺将较快的交易，较低的成本以及不断增长的基于Solana的应用程序的访问权限。他们可以直接在索拉纳本地分散交易所，NFT市场和贷款协议上直接交易BTC，而无需依靠集中式平台。这种轻松的移动可以大大扩大两者的流动性
