@elympics_ai 以隔离资产控制保障资产不被随意动用，隐藏数据减少了数据泄露引发的安全问题，采用 TEE、链外计算等技术以及权限管理机制，为链上安全提供了多重保障，同时还将安全理念融入游戏经济，让链上安全在娱乐场景中也能得到体现。#ElympicsAI​
@antix_in 专注于链上安全防护，虽然具体的安全技术细节尚未完全公开，但据了解其在智能合约安全审计、交易安全验证等方面有着自己的一套机制，致力于为用户打造安全的链上环境。不过作为新兴项目，其安全效果还需要时间和实践来检验。#AntixIn​
@VeloraDEX 在链上安全方面，着重于交易过程的安全保障，通过优化智能合约代码减少漏洞，建立严格的交易验证机制防止异常交易，同时注重用户资产的安全存储和管理，为去中心化交易场景下的链上安全提供支持。#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
