In an era where blockchain technology promises a decentralized future, the security and correctness of digital assets and smart contracts have never been more paramount. With over $4 billion lost to hacks in 2019 alone, adequate security measures are necessary. As blockchain’s openness often exposes it to vulnerabilities, Shentu Chain emerges as a foundational element of trust and security. Utilizing advanced technologies, it aims to decentralize security, offering on-chain solutions that maintain the integrity of digital assets. Through its strategic approach, Shentu Chain serves as a key player in establishing provable trust within the blockchain domain, ensuring the technology’s potential benefits everyone.

What is Shentu (CTK)?

Founded in 2018 by Columbia University graduate Ronghui Gu and his Ph.D. advisor, Yale University graduate Zhong Shao, Shentu (originally CertiK) embarked on a mission to elevate the security of blockchain ecosystems. As professors of Computer Science with a passion for programming languages, Gu and Shao sought to mitigate the vulnerabilities inherent in blockchain technology. Their ambition led to the creation of CertiK, a company dedicated to enhancing the security of blockchain projects, monitoring them, and ensuring the safety of smart contracts through comprehensive stages: pre-development, development, and post-development.

To achieve this, CertiK launched a mainnet initially named CertiK Chain, later rebranded as Shentu Chain. This move symbolized the platform’s commitment to offering multi-faceted protection, incorporating tools such as the Shentu Security Oracle, the DeepSea programming language, and ShentuShield.

Shentu’s innovative approach attracted significant attention, leading to a successful fundraising effort. The project raised $39.43 million through two rounds of private token sales, selling 38.00% of the total CTK token supply at prices of $0.77 and $1.90 per CTK during the first and second sales, respectively. This financial backing underscored the blockchain community’s confidence in Shentu’s potential to contribute to the ecosystem’s security and trustworthiness significantly.

How Does Shentu Work? Virtual Machine and Security Features

At the heart of Shentu’s innovative approach to blockchain security lies the Shentu Certified Virtual Machine (CVM), a groundbreaking platform that redefines the role of security in blockchain technology. Traditional virtual machines, while integral to blockchain operations, have typically treated security as an external, off-chain concern. These traditional systems perform formal verification outside of the virtual machine environment, rendering the results invisible to both chain operation and VM execution. This separation limits the potential for dynamic, on-chain responses to security assessments, a gap the CVM aims to bridge.

The CVM introduces a paradigm shift by embedding security as a core value within its operational framework. This integration allows for a more nuanced interaction among smart contracts, enabling them to adjust their behavior based on the security profiles of their counterparts. Such a mechanism mirrors real-world practices where the perceived security or trustworthiness of entities often influences decisions. By allowing smart contracts to differentiate interactions based on security levels, the CVM fosters a more secure and efficient blockchain ecosystem.

Supporting this advanced framework, the CVM utilizes the DeepSEA programming language, designed to facilitate the development of highly complex code while ensuring its formal verification through mathematical proofs. This approach significantly reduces the trusted computing base (TCB), enhancing the overall security of the VM code. The CVM is not only capable of executing bytecode and proofs generated by DeepSEA’s certified compiler but also enforces a rigorous standard of security, sandboxing, and isolation for code that has not undergone complete formal verification.

Through its sophisticated design, the CVM establishes a clear hierarchy of VM code security, allowing diverse technologies and vendors to coexist and interact with transparency and mutual understanding. This hierarchy ranges from the highest security level, characterized by trustless VM code backed by complete mathematical proof, to lower levels where non-secure VM code may operate with certain restrictions. This inclusive yet stratified approach ensures that the CVM can support various smart contract functionalities while maintaining stringent security standards.

The Shentu Certified Virtual Machine (CVM) stands as a cornerstone of Shentu’s security architecture, bringing the concept of on-chain security intelligence to the forefront of blockchain technology. By making security a dynamic, integral part of the blockchain environment, the CVM paves the way for safer, more reliable smart contract interactions. This security foundation is further augmented by Shentu’s innovative features, such as the Security Oracle and ShentuShield, which will be explored in the following sections, underscoring Shentu’s comprehensive approach to blockchain security.

Security Features

Shentu’s innovative approach to blockchain security is further enhanced through two pivotal features: the Shentu Security Oracle and ShentuShield. These components serve as the backbone for a secure, trustworthy blockchain ecosystem, addressing critical needs for real-time security insights and financial protection against losses.

The Shentu Security Oracle emerges as a critical mechanism, bridging the gap between the blockchain’s on-chain activities and the off-chain world of security assessments. In traditional settings, oracles serve as bridges for external data, but Shentu’s Oracle innovates by focusing specifically on security intelligence. It harnesses a decentralized network of security experts who assess the reliability of smart contracts, with their insights aggregated into a dynamic, on-chain security score. This score enables users and smart contracts to gauge the security of interactions in real-time, influencing decisions on transaction sizes or even halting potentially risky engagements based on the assessed security level. This continuous, agile assessment model ensures that projects can adapt and enhance their security posture, keeping pace with the evolving landscape of threats.

ShentuShield then builds on this foundation by providing a decentralized financial safety net for the blockchain community. In an ecosystem where billions have been lost to hacks and errors, ShentuShield offers a communal pool of CTK—the native currency of Shentu Chain—set aside to reimburse losses due to hacks, code malfunctions, or other irretrievable loss scenarios. This dual-layer system allows participants to either contribute to the pool, earning rewards while providing a safety net, or reserve a portion of this pool for protection against asset loss. The process is governed democratically, with the community voting on reimbursement claims, ensuring the system remains fair and resistant to manipulation.

The synergy between the Security Oracle and ShentuShield addresses two of the most pressing concerns in the blockchain space: ensuring the security of interactions and providing a mechanism to mitigate the consequences of security failures. By embedding these functionalities directly onto the blockchain, Shentu offers a more transparent, responsive, and democratic approach to security and asset protection.

In conclusion, Shentu’s Security Oracle and ShentuShield are more than just features; they represent a comprehensive approach to blockchain security and asset protection. These innovations offer dynamic, real-time security assessments and a decentralized safety net, respectively, addressing the dual challenges of securing blockchain interactions and providing recourse in the event of loss. Together, they embody Shentu’s commitment to elevating trust and security in the blockchain ecosystem, making it safer and more reliable for all users.
