大家早上好，今天和大家聊聊 @cookiedotfun 上10大項目的鏈上安全問題，先指出 Web3 項目在鏈上安全的常見問題，再分別介紹各個項目在鏈上安全方面的舉措及注意事項。

@OpenledgerHQ 在鏈上安全方面，依托分布式加密存儲築牢數據安全防線，去中心化身份體系保障用戶身分不被冒用，智能合約權限控制嚴格限制非授權操作，零知識證明技術在保護隱私的同時也增強了交易安全性。此外，平台會定期對安全策略進行審計和更新，核心是讓用戶始終掌控自己的資產和數據安全。#OpenLedger​
@recallnet 致力於實現鏈上數據安全使用，其設計理念在保障數據可用的同時，通過特定技術手段減少安全漏洞。不過該項目相對較新，鏈上安全的實際效果還需要經過代碼全面檢查和實際應用檢驗，所以用戶使用時要提高警惕，妥善保管相關憑證，確保鏈上操作安全。#Recall​
@LABtrade_ 注重鏈上安全防護，採用分布式加密存儲保護數據不被篡改和泄露，去中心化身份認證確保用戶身分真實可靠且安全，智能合約權限控制嚴謹規範操作流程，零知識證明技術爲交易和數據交互增添安全保障。平台會定期審計並更新安全策略，讓用戶在匿名操作的同時，也能安心保障鏈上資產和數據安全。#LAB​
@vooi_io 推測會運用多種鏈上安全技術，比如交易加密、存儲安全防護等手段來保障鏈上安全，具體的安全機制細節還有待官方公布。作爲新平台，其鏈上安全的實際效果需要經過充分的測試驗證，用戶在使用初期需謹慎對待。#VOOI​
@build_on_bob 基於 BOB 鏈的 ZK-Rollup 架構，在鏈上安全方面，零知識證明技術爲交易提供了安全隱私保障，鏈下加密計算減少了鏈上數據暴露的安全風險，交易數據脫敏上鏈進一步降低了信息泄露風險。用戶私鑰自持增強了資產控制權的安全性，支持權限自定義讓用戶能根據自身需求設置安全策略。但由於是新生態，安全機制的穩定性和可靠性還需驗證，用戶使用時務必管理好私鑰，確保鏈上安全。#BuildOnBOB​
@tenprotocol 依靠硬件加密隔離技術，從硬件層面爲鏈上數據和操作提供安全保障，靈活的隱私控制機制也間接增強了鏈上安全，分散驗證方式避免了單點故障帶來的安全風險，在兼顧合規和開發靈活度的同時，爲鏈上安全保駕護航。#TenProtocol​
@Almanak__ 通過隔離資產控制權，防止非授權方對資產進行操作，隱藏策略執行減少了因策略暴露帶來的安全威脅，運用加密技術和權限管理雙重手段，確保鏈上數據和操作在可用範圍內的安全性，實現了鏈上資產和策略的安全防護。#Almanak​
@elympics_ai 以隔離資產控制保障資產不被隨意動用，隱藏數據減少了數據泄露引發的安全問題，採用 TEE、鏈外計算等技術以及權限管理機制，爲鏈上安全提供了多重保障，同時還將安全理念融入遊戲經濟，讓鏈上安全在娛樂場景中也能得到體現。#ElympicsAI​
@antix_in 專注於鏈上安全防護，雖然具體的安全技術細節尚未完全公開，但據了解其在智能合約安全審計、交易安全驗證等方面有着自己的一套機制，致力於爲用戶打造安全的鏈上環境。不過作爲新興項目，其安全效果還需要時間和實踐來檢驗。#AntixIn​
@VeloraDEX 在鏈上安全方面，着重於交易過程的安全保障，通過優化智能合約代碼減少漏洞，建立嚴格的交易驗證機制防止異常交易，同時注重用戶資產的安全存儲和管理，爲去中心化交易場景下的鏈上安全提供支持。#VeloraDEX
The main drawbacks of Web3 projects in terms of on-chain security are as follows: Smart contract vulnerabilities are prone to attacks, threatening asset security; inadequate security mechanisms during cross-chain interactions pose risks of data leakage and asset loss; and security loopholes in decentralized identity management make user information vulnerable to theft.​
@OpenledgerHQ, in terms of on-chain security, relies on distributed encrypted storage to build a solid defense line for data security. Its decentralized identity system ensures that user identities are not fraudulently used. Strict control over smart contract permissions restricts unauthorized operations, and zero-knowledge proof technology enhances transaction security while protecting privacy. In addition, the platform regularly audits and updates its security strategies, with the core being to allow users to always have control over the security of their assets and data. #OpenLedger​
@recallnet is committed to enabling the secure use of on-chain data. Its design concept, while ensuring data availability, reduces security vulnerabilities through specific technical means. However, since the project is relatively new, the actual effect of its on-chain security still needs to undergo comprehensive code inspections and practical application tests. Therefore, users should be vigilant when using it, properly keep relevant credentials, and ensure the security of on-chain operations. #Recall​
@LABtrade_ focuses on on-chain security protection. It adopts distributed encrypted storage to protect data from tampering and leakage. Decentralized identity authentication ensures that user identities are authentic, reliable, and secure. Strict control over smart contract permissions standardizes operational processes, and zero-knowledge proof technology adds a security guarantee to transactions and data interactions. The platform regularly audits and updates security strategies, allowing users to safely protect their on-chain assets and data while operating anonymously. #LAB​
@vooi_io is speculated to utilize a variety of on-chain security technologies, such as transaction encryption and storage security protection, to ensure on-chain security. The specific details of its security mechanisms have yet to be announced by the official. As a new platform, the actual effect of its on-chain security needs to undergo sufficient testing and verification, and users should be cautious in the initial stage of use. #VOOI​
@build_on_bob, based on the ZK-Rollup architecture of the BOB chain, in terms of on-chain security, zero-knowledge proof technology provides security and privacy guarantees for transactions. Off-chain encrypted computing reduces the security risks of on-chain data exposure, and desensitized transaction data being uploaded to the chain further lowers the risk of information leakage. Users' self-holding of private keys enhances the security of asset control rights, and support for permission customization allows users to set security strategies according to their own needs. However, as a new ecosystem, the stability and reliability of its security mechanisms still need to be verified. When using it, users must manage their private keys properly to ensure on-chain security. #BuildOnBOB​
@tenprotocol relies on hardware encryption isolation technology to provide security guarantees for on-chain data and operations at the hardware level. Its flexible privacy control mechanism also indirectly enhances on-chain security, and the decentralized verification method avoids security risks caused by single points of failure. While balancing compliance and development flexibility, it safeguards on-chain security. #TenProtocol​
@Almanak__ prevents unauthorized parties from operating assets by isolating asset control rights. Hiding strategy execution reduces security threats caused by strategy exposure. It uses dual means of encryption technology and permission management to ensure the security of on-chain data and operations within the available range, achieving security protection for on-chain assets and strategies. #Almanak​
@elympics_ai ensures that assets are not arbitrarily used through isolated asset control. Hiding data reduces security issues caused by data leakage. It adopts technologies such as TEE and off-chain computing, as well as permission management mechanisms, to provide multiple guarantees for on-chain security. At the same time, it integrates security concepts into the game economy, allowing on-chain security to be reflected in entertainment scenarios. #ElympicsAI​
@antix_in focuses on on-chain security protection. Although the specific details of its security technologies have not been fully disclosed, it is understood that it has its own set of mechanisms in aspects such as smart contract security auditing and transaction security verification, dedicated to creating a secure on-chain environment for users. However, as an emerging project, its security effect still needs time and practice to verify. #AntixIn​
@VeloraDEX, in terms of on-chain security, focuses on ensuring the security of the transaction process. It reduces vulnerabilities by optimizing smart contract code, establishes strict transaction verification mechanisms to prevent abnormal transactions, and pays attention to the secure storage and management of user assets, providing support for on-chain security in decentralized trading scenarios. #VeloraDEX
