Shentu's Positioning and Significance

In 2020, CertiK launched Shentu (CTK), aiming to address security challenges in blockchain networks and smart contracts. As a pioneering blockchain security platform, Shentu plays a crucial role in the fields of DeFi, smart contract auditing, and network security.

As of 2025, Shentu has become a key player in blockchain security, with an active developer community and a focus on providing real-time security metrics for audited networks. This article will delve into its technical architecture, market performance, and future potential.

Origins and Development History

Birth Background

Shentu, originally launched as CertiK (CTK) in October 2020, was created to tackle the growing security concerns in the blockchain industry. It emerged during a period of rapid blockchain adoption and increasing DeFi exploits, aiming to provide robust security solutions for blockchain networks and smart contracts.

The launch of Shentu brought new possibilities for enhancing the security and reliability of blockchain projects and decentralized applications.

Important Milestones

• 2020: Main network launch, introducing real-time security metrics for audited networks.
• 2021: Rebranded from CertiK to Shentu in September, focusing on cross-chain compatibility and delegated proof-of-stake consensus.
• 2025: Ecosystem expansion, with CertiKShield offering decentralized reimbursement for lost or stolen crypto assets due to security issues.

With support from its community and the Shentu Foundation, Shentu continues to optimize its technology, security features, and real-world applications in blockchain security.

How Does Shentu Work?

Decentralized Control

Shentu operates on a decentralized network of computers (nodes) spread across the globe, free from control by any single entity. These nodes collaborate to validate transactions and ensure system transparency and attack resistance, enhancing network resilience.

Blockchain Core

Shentu's blockchain is a public, immutable digital ledger that records every transaction. Transactions are grouped into blocks and linked through cryptographic hashes, forming a secure chain. Anyone can view the records, establishing trust without intermediaries.

Ensuring Fairness

Shentu employs a delegated proof-of-stake (DPoS) consensus mechanism to validate transactions and prevent fraudulent activities like double-spending. Validators participate in maintaining network security by staking tokens and running nodes, receiving CTK rewards for their efforts.

Secure Transactions

Shentu uses public-private key encryption to protect transactions:

• Private keys (like secret passwords) are used to sign transactions
• Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security while maintaining transaction pseudonymity. Additionally, Shentu incorporates advanced security features like its security Oracle network and the CertiKShield reimbursement system for enhanced protection against potential losses due to security breaches.
