Instruxi 與 Space and Time 合作實現超大規模資料可用性

Instruxi (IX)很高興地宣布與Space and Time (SxT) 建立合作夥伴關係並進行集成，Space and Time (SxT) 是一種尖端資料倉儲，可保護低階資料管理任務，同時保持業界最關鍵工作負載所需的性能標準。

Instruxi 是一家致力於創建安全、透明的資料共享平台的公司，該平台優先考慮用戶同意和隱私。Instruxi 使用戶能夠控制誰有權存取其資料以及如何使用資料。

Instruxi 的方法被稱為“意圖和同意”，為用戶提供了更大的透明度和對其數據的控制，這有助於在數據共享過程中建立信任和信心。透過細粒度地強制執行同意，Instruxi 可確保使用者了解其資料的使用方式，並且如果使用者對預期用途不滿意，可以撤回同意。

Instruxi 方法的另一個好處是，它使組織能夠更輕鬆、更有效率地共享數據，而不會影響安全或隱私。透過提供安全、透明的資料共享平台，Instruxi 有助於降低資料外洩和其他安全威脅的風險，同時確保資料僅與擁有適當權限的授權使用者共用。

Instruxi 透過一種名為「策略證明」的新穎協議來促進這一點。Proof-of-Policy 是 Instruxi 開發的協議，旨在實現 Web2 服務的通用資料共享，同時確保資料消費是在資料所有者的正確意圖和同意的情況下完成的。該協議的工作原理是定義管理資料使用的策略並創建基於智能合約的系統來執行這些策略。

Instruxi 在兩個方面整合空間和時間

首先，Instruxi 的 SxT 連接器與其資料網格平台 Neutrino Mesh 捆綁在一起，供所有使用者使用。借助此連接器，網格開發人員可以建立複雜的資料產品，將 SxT 的可驗證資料與大多數外部資料來源（從 ERP 系統到傳統 SQL 資料庫，再到高吞吐量流來源）混合在一起。這意味著網格開發人員可以使用相同的 SQL 查詢來查詢多個資料來源，包括 SxT。這也意味著用戶可以從 30 個本機 Neutrino Mesh 連接器中的任何一個提取和轉換數據，並將該數據從任何受支援的系統直接載入到 SxT 中。Neutrino Mesh 旨在抽象化連接多個資料來源、在 SxT 中配置公私金鑰授權的複雜性，並最終允許資料擁有者專注於使用策略證明來管理高度可用的資料目錄。

為了獲得授權，使用者發起質詢並使用其公鑰提交簽署的回應。公鑰必須與相關策略的所有者相對應才能接收 JWT 令牌。此令牌包含在 Instruxi 的空間和時間連接器上產生查詢範圍所需的元資料。有關更多詳細信息，請參閱Trino 。

‍

其次，Instruxi 很高興地宣布其首次實現虛擬 NFT (vNFT) 將於 2023 年春季上線。vNFT 是 Instruxi 創造的術語，是一種新型動態 NFT，只能透過 SxT 提供的加密驗證資料來實現。如今動態不可取代代幣（dNFT）的主要問題是它們本質上是僵化的。這些 NFT 的元資料是使用預言機或由鏈外實體發起的交易在幕後熱交換的，因為元資料通常保存在某些不可變託管服務（如 IPFS）的 URI 中。vNFT 是一種不可替代的代幣，其元資料儲存在鏈下資料倉儲中。vNFT 是動態的，並且會隨著資料倉儲中基礎資料的變化而變化。這意味著單一 vNFT 可以代表複雜且不斷發展的資料集，使其成為資料驅動的應用程式和服務的強大工具。

以下是 Instruxi 提議的 vNFT 元資料規範的範例：

NFT 智能合約通常不會直接保存數據，而是使用元數據 URI 來引用鏈下數據。 有關更多信息，請參閱 OpenSea 的元資料標準，或在此處查看完整的 vNFT 範例元資料規格。

vNFT 的主要好處之一是它們可以幫助提高資料共享的透明度和問責制。透過使用 vNFT 來表示資料集，使用者可以對他們正在使用的資料的準確性和來源更有信心，因為 vNFT 可以作為資料來源和完整性的加密證明。

借助 SxT 和 SQL 證明，vNFT 能夠增加標記大量資料所需的規模水平，而不會影響傳統去中心化技術提供的加密保證。SxT 透過使用區塊鏈預言機中的行業標準來驗證傳入查詢，確保下游應用程式的結果集防篡改，從而實現這一點。

關於策略證明的更多信息

政策證明是執行意圖和同意的基礎。策略定義了資料可以被存取、使用和共享的條件。這些策略可以進行定制，以滿足不同資料所有者的特定需求，並且可以涵蓋廣泛的場景，例如定義誰有權存取資料、如何使用資料以及可以儲存多長時間。

Neutrino Mesh 智能合約衍生的策略提供了所有資料交易的防篡改記錄，確保資料使用透明且可審計。該系統還確保所有資料交易都符合資料所有者定義的策略。這有助於防止未經授權的存取或濫用數據，並確保數據用於預期目的。

與其他資料共享協定（例如依賴集中中介或複雜存取控制機制的協定）相比，策略證明的設計更加透明、安全和有效率。透過使用戶能夠控制誰有權存取其數據以及如何使用數據，策略證明可以幫助降低資料外洩和其他安全威脅的風險，同時還促進更有效的資料共享和協作。

對 Instruxi 來說，SxT 不僅是另一個強大的資料倉儲，更重要的是，它是 Instruxi 與使用者建立信任的一種方式。Instruxi 的精神植根於道德資料管理、分發和商業化的理念。Instruxi 與 Space and Time 的合作標誌著安全性、通用資料共享向前邁出了重要一步。透過利用 SxT 資料倉儲，Instruxi 能夠為其客戶提供無與倫比的見解和資料驅動的解決方案，促進他們的分析和人工智慧專案以及應用程式和 dApp 的建置。數據共享的未來看起來一片光明，Instruxi 很高興能與 SxT 在這個新興市場的前沿合作。

On-chain privacy refers to the ability of a blockchain network to protect the privacy of its users. In traditional blockchain networks, all transactions are visible on the blockchain, making it easy to track the flow of funds and trace the identity of the sender and receiver. This lack of privacy has been a major concern for many users, particularly in the financial sector. On-chain privacy solutions aim to address this issue by introducing privacy-enhancing technologies to the blockchain.

One such solution is Manta Network, a privacy-focused decentralized exchange (DEX) built on the Polkadot network. Manta Network is designed to provide users with a high level of privacy and security, while still allowing them to trade a wide range of assets. It achieves this through the use of zero-knowledge proofs, which allow users to prove that they own a particular asset without revealing any information about the asset or its owner.

Zero-knowledge proofs are a powerful tool for ensuring privacy in decentralized networks. In simple terms, a zero-knowledge proof is a cryptographic method that allows one party to prove to another party that they know a particular piece of information without revealing the information itself. This means that users can prove that they have the right to perform a particular action, such as transferring an asset, without revealing any information about themselves or the asset in question.

Manta Network leverages zero-knowledge proofs to ensure that all transactions on its network are private and secure. This means that users can trade assets on the network without worrying about their transactions being traced or their identity being revealed. In addition, Manta Network is designed to be fully decentralized, meaning that there is no central authority controlling the network. This ensures that users have full control over their assets and can trade them with complete confidence.

In conclusion, privacy is a fundamental right that is becoming increasingly important in our digital world. On-chain privacy solutions like Manta Network are essential for ensuring that users can trade assets with complete confidence, while still maintaining their privacy and security. Zero-knowledge proofs are a powerful tool for achieving this goal, and we can expect to see more blockchain networks and decentralized applications leveraging this technology in the future.

On-chain privacy refers to the ability to keep transactions and data confidential on a blockchain network. This is particularly important in public blockchain networks like Bitcoin and Ethereum, where all transactions are visible to everyone. While this transparency is a crucial aspect of blockchain, it also poses a challenge for privacy. On-chain privacy solutions aim to overcome this challenge by providing a way to keep sensitive data confidential while maintaining the integrity and security of the blockchain network.

Manta Network is one such solution that aims to provide on-chain privacy for DeFi (decentralized finance) transactions. Manta Network is a privacy protocol built on the Polkadot network that allows users to conduct private transactions on-chain. It uses zero-knowledge proofs, a cryptographic method that enables the verification of a statement without revealing any information beyond the statement itself. Zero-knowledge proofs provide a way to prove that a transaction is valid without revealing any details about the sender, receiver, or transaction amount.

The Manta Network achieves its privacy goals by implementing two core components: the Manta Protocol and the Manta Bridge. The Manta Protocol is responsible for providing privacy protection for DeFi transactions by enabling the use of zero-knowledge proofs. The Manta Bridge, on the other hand, is a decentralized exchange (DEX) that allows users to trade cryptocurrencies anonymously without revealing their identity.

The Manta Network provides several benefits for users who value their privacy. Firstly, it ensures that transactions remain confidential, so users don't have to worry about their financial information being exposed to others. Secondly, it provides a way to conduct transactions anonymously, which is particularly important for individuals who want to maintain their privacy. Finally, it enhances the security of the blockchain network by preventing malicious actors from accessing sensitive information.

In conclusion, privacy is an essential aspect of our lives, and it's crucial to protect it in the digital age. On-chain privacy solutions like the Manta Network provide a way to keep sensitive data confidential while maintaining the transparency and security of the blockchain network. With zero-knowledge proofs, Manta Network ensures that transactions remain private and secure, giving users the confidence they need to conduct transactions on the blockchain network. As the blockchain ecosystem continues to grow, the need for privacy solutions will only increase, and the Manta Network is well-positioned to meet this demand.

随着区块链数量的激增，参与者对互操作性解决方案的需求也会随之而来。截至目前，市场上已有超过40个跨链桥项目，仅从以太坊L1转移出去的资产就达到了260亿美元以上。

这还不到加密市场3万亿美元总市值的1%，而随着跨链桥基础设施变得强大，以及跨链流动性变得更强，我们可以预期这个百分比会变得更高。由于加密市场本身有足够的增长空间（相比之下，全球股票市场的规模为122万亿美元），跨链基础设施市场也可能会达到数万亿美元的规模。

今天，大多数的跨链桥解决方案都是特定于链、资产或特定于应用的，虽然它们是将以太坊用户迁移到L2 的有效短期解决方案，但当流动性不再分散时，加密网络的真正潜力就会被释放，并且应用程序从一开始就可实现跨链原生。

Connext正在努力使这一愿景成为现实，Connext 是一种互操作性协议，其可在兼容EVM 的区块链之间实现快速、非托管的跨链传输和合约调用。

Connext 是一个流动性网络：一个由节点（router）组成的链下点对点网络，这些节点（router）持有发送和接收链上的资产“库存”。用户通过与可访问所需资产流动性的router网络进行交易来跨链转移资金。

用户在发送链上“锁定”资金，并在接收链上“解锁”相应金额（减去费用）。 反之亦然，router在交易开始时会在接收链上为用户锁定资金，并在发送链上除了收取费用外，还可以claim锁定的资金。

随着经济吞吐量的飙升，跨链传输的长期基础层应该具有最大的可扩展性和高度安全性。而流动性网络非常适合这一点，因为它们是：

1、信任最小化：由于锁定机制，用户可以确认router不会卷款逃跑。Connext 的非托管跨链传输协议 (NXTP) 是唯一不添加新信任假设的通用互操作性解决方案。依赖外部验证器的跨链桥，从根本上来说不太安全，因为用户需要信任第三方验证者提供资金和数据。

2、可扩展：使用链自己的验证器集来验证交易的跨链桥，具有更强的信任保证。但是，它们需要为每个链对定制，并且不能像liquidity networks那样快速添加对新链的支持（例如，以太坊rollup桥只能在该rollup和以太坊L1之间使用）。而Connext可以轻松地将新的链连接到网络，从而快速扩展到其他生态系统。

3、资本效率：担保/保险桥解决方案要求验证者抵押资产来为网络提供服务。这种抵押品需要与跨链桥的经济吞吐量成比例地扩展，否则激励就会失效。对于像Connext这样的流动性网络，网络可安全促进的经济吞吐量没有博弈论上限，因为资本锁定与安全模型是解耦的。

4、更优的用户体验：由于验证在流动性网络中本地进行（在交易对手之间，而不需要全局共识），因此跨链转移速度很快。只要链与EVM兼容，Connext协议就可以快速支持，无论L1还是L2。此外，Connext还可以让用户完全避免L1交易成本。

这些权衡使得 Connext 处于跨链转移和合约调用的最佳位置。

套利激励下的流动性再平衡

跨链交易量是流动性网络的关键增长指标，然而，单方向的大量交易会迅速耗尽另一侧的流动性。

为了解决这个问题，Connext 在 AMM 曲线上动态定价流动性，模仿像 Curve 这样的AMM。资产价格随着每条链上可用流动性比率的变化而变化。流动性越不平衡，这种价差就越大。

这为做市商提供了诱人的套利激励，他们已经在 Uniswap 等 AMM 中利用了此类机会。使用 Connext 的虚拟 AMM，也可以执行跨链套利。

虚拟 AMM 和router拍卖一起不断地重平衡整个网络的流动性，允许在保持跨链价格平衡的同时扩大交易量。

此外，由于交易对手在链外协商路线和定价，因此第三方不可能进行抢先交易。
