Shentu

Shentu Chain is a blockchain with a strong focus on security, utilizing a delegated proof-of-stake system to ensure reliable execution of critical applications such as DeFi, NFTs, and autonomous vehicle systems. It emphasizes cross-chain compatibility, functioning as a Cosmos Hub with full support for both EVM and Hyperledger Burrow, as well as compatibility with eWASM and AntChain from Ant Financial. The Security Oracle provides security assessments across protocols by monitoring and flagging various potential threats to on-chain transactions before they cause harm. Based on their security ratings, blockchain projects that undergo audits may qualify for ShentuShield membership—a flexible, decentralized reimbursement program for crypto assets that are lost or stolen due to security lapses. This membership is accessible to community members involved with these qualifying blockchain projects, offering a safeguard for crypto asset holders in case of unexpected events.

Projects can naturally develop in DeepSEA, a highly secure programming language backed by the Ethereum Foundation, Qtum Foundation, and IBM. DeepSEA integrates seamlessly with the Shentu Virtual Machine (SVM), which ensures complete compatibility with EVM. The SVM leads the way in providing smart contract and blockchain security information, allowing for novel access, evaluation, and integration of risk considerations into smart contract decisions. CTK serves as the native digital utility token of Shentu Chain, acting as the primary resource for executing functions like operating the Security Oracle and ShentuShield systems, covering transaction fees on Shentu Chain, and participating in governance votes within the network.

The Security Oracle operates as a decentralized network of operators deploying top-tier security technologies to assess the trustworthiness of essential smart contracts, particularly those in DeFi applications. These operators earn CTK rewards for providing real-time, constantly updated security scores. The Security Oracle is compatible with any protocol, enabling users to make informed choices before engaging with smart contracts. Smart contracts connected to the Security Oracle can detect and block malicious transactions, thus safeguarding crypto assets from potential loss. Additional information can be accessed here.

ShentuShield offers a decentralized membership framework designed to facilitate the reimbursement of cryptocurrency that has been lost or stolen from any protocol. Reimbursement decisions are exclusively managed by ShentuShield members, who can be either blockchain projects or individual community supporters. Participants can join as Collateral Providers, contributing their own collateral, or as Shield Purchasers, obtaining protection for their crypto, or they can choose to do both. Collateral Providers receive staking rewards on their staked CTK and share in the fees paid by Shield Purchasers. Shield Purchasers secure funds from the Pool for potential reimbursements of their crypto assets, paying a CTK fee that benefits Collateral Providers. A continually updated list of publicly auditable clients is available here.

DeepSEA is a secure programming language and compilation toolchain that works seamlessly with the SVM, EVM, eWASM, and AntChain from Ant Financial. It has received research grants from the Ethereum, IBM-Columbia, and Qtum foundations to advance its development as a hyper-secure programming language. While coding in DeepSEA, automatic generation of mathematical proofs ensures alignment between the intended specifications and the actual code, enhancing the depth of formal verification and correctness.

Although fully compatible with EVM, the Shentu Virtual Machine (SVM) is designed following the widespread x86–64 OS process model found in computers globally, with potential future extensions to arm64. The SVM allows the implementation of on-chain security parameters, enabling smart contracts to interact with varying levels of risk tolerance. Furthermore, the SVM includes a smart contract sandbox feature, which isolates the operation of smart contracts, particularly those not yet secured, from the broader system environment.
