Shentu (CTK)

Overview

Shentu is a blockchain built around a specific idea: security information should be useful while people and applications are using a network, not only when developers review code before launch. Its native token, CTK, helps run the chain and supports services designed to assess smart contracts and coordinate security work. Shentu is part of the Cosmos ecosystem, which gives it a framework for building blockchain applications and connecting with other networks. (shentu.org)

A smart contract is a program that carries out actions on a blockchain. Shentu’s design brings several kinds of security work closer to those programs, including recorded certificates, security scores, and community decisions. These tools serve different purposes. A certificate records an assessment, an oracle supplies information that an application can use, and governance lets participants decide on network changes. CTK links these activities through fees, staking, and voting. (shentu.org)

History & Team

From CertiK Chain to Shentu

Shentu grew from work associated with CertiK, a blockchain security company co-founded by computer science professors Ronghui Gu and Zhong Shao. CertiK traces its founding to December 2017. Gu is associated with Columbia University, while Shao is associated with Yale University. Their research backgrounds include secure software and methods for checking whether programs behave as intended. The blockchain was first known as CertiK Chain before adopting the Shentu name.

CTK was available through Binance Launchpool in October 2020, during the chain’s early period. The project’s published token allocation included two private-sale groups, a team allocation, foundation and community pools, and a pool set aside for ShentuShield. Those are categories in the token distribution; they do not identify every individual backer. Today, the Shentu Foundation publishes chain software and information about applications built in its ecosystem. (binance.com)

Technology & How It Works

Validators and on-chain records

Shentu uses a delegated proof-of-stake model. Validators are computers that check transactions and help produce blocks. CTK holders can delegate tokens to a validator, adding to that validator’s voting power and sharing in its block rewards. This lets someone take part in network security without operating a validator computer. Shentu’s technical design also draws on the Cosmos SDK and its associated consensus technology. (shentu-chain.gitbook.io)

The chain can store security-related certificates. Such records give applications a way to find information about reviewed software on-chain rather than relying only on a report stored elsewhere. Shentu’s virtual-machine design also supports smart contracts that can consult security information when deciding how to interact with another contract. The project’s technical work includes DeepSEA, a programming language developed for writing contracts whose behavior can be checked using mathematical methods. (shentu.org)

The Security Oracle

Shentu’s Security Oracle is designed to answer questions about a contract’s security at the time the information is needed. An application can request an assessment; security operators supply findings; and an on-chain process combines their responses into a result. CTK provides the incentive for operators who do this work. The design also allows results to be passed to an application on another blockchain. In simple terms, the oracle turns security research into information that software can request and use. (shentu.org)

Shentu has also expanded its approach to verifiable knowledge. OpenMath allows mathematical proofs to be checked and recorded on-chain so that later work can build on them. A 2025 chain upgrade added OpenMath features, and a 2026 upgrade added a related certificate type and changes to how certificate records are searched. (github.com)

Tokenomics & Utility

What CTK does

CTK has several connected jobs. It pays transaction fees on Shentu Chain, can be staked with validators, and gives stakers a role in governance votes. The project’s Security Oracle design uses CTK to pay for requested analysis and reward operators. ShentuShield, a system of community-funded reimbursement pools, also uses CTK in its collateral and claims design. These uses tie the token to both ordinary chain activity and the project’s security-focused services. (shentu.org)

The original allocation described by Binance Research was 29% for the first private sale, 9% for the second, 10% for the team, 25% for the foundation, 17.5% for the community pool, 8% for the ShentuShield pool, and 1.5% for Launchpool. These figures describe the initial distribution plan. CTK is also issued as staking rewards, so the original allocation alone does not describe the chain’s later token supply. (binance.com)

Staking rewards are shared between validators and the people who delegate to them, with the validator’s commission affecting the delegator’s share. When a holder undelegates CTK, the chain’s documented waiting period is 21 days; the tokens do not earn staking rewards during that period. This timing is part of how the network organizes participation in block production. (shentu-chain.gitbook.io)

Ecosystem & Use Cases

Shentu’s tools address different stages of a software project. Developers can use secure-programming and verification methods while building a contract. Once software is running, certificates and oracle results can make security information available to applications. Governance then provides a way for CTK stakers to take part in decisions about network operations and upgrades. Together, these features connect development, live use, and community oversight. (shentu.org)

ShentuShield is a reimbursement-pool model built around contributed funds and community decisions on claims. Its design uses CTK as collateral and for payments associated with approved claims. This makes it a distinct part of the ecosystem: rather than supplying a score about software, a pool organizes how participating members respond to eligible losses. (shentu.org)

Other applications show how broadly the chain interprets security and trust. OpenBounty connects projects offering bug bounties with researchers who submit findings. OpenMath focuses on proofs that others can check and reuse. The Shentu website also presents a multisignature wallet for managing assets through shared approval. Each application uses a different form of coordination, from finding software flaws to verifying mathematics or approving a transaction with several signers. (openbounty.shentu.org)

Advantages & Challenges

Shentu’s main strength is its focused design. Validator staking secures the chain, while certificates, oracle requests, and governance give security information a place in everyday blockchain activity. Its Cosmos-based structure helps it work with the wider interchain ecosystem, and projects such as OpenBounty and OpenMath extend the idea beyond smart-contract scoring. (shentu.org)

The challenge is bringing these pieces together in a way developers will use. An oracle result becomes useful to an application when that application can request, receive, and act on it. Certificates need clear meaning so that readers and programs can interpret them. Reimbursement pools depend on members contributing funds and making decisions on claims. For CTK holders, validator choice also matters because uptime, commission, and voting power shape the staking experience. These are practical questions of integration and participation, not just matters of chain design. (shentu.org)

Where to Buy & Wallets

CTK is available on Binance and MEXC. Exchange availability and supported deposit networks depend on the platform and the user’s location. CTK is the native token of Shentu Chain, so a withdrawal intended for a Shentu wallet needs the corresponding network selection and address format. (binance.com)

Shentu DeepWallet supports storing and sending CTK, delegating it to validators, claiming rewards, and participating in governance. It is a non-custodial wallet, meaning the user controls the wallet’s private keys. A holder who plans to stake can compare validators by uptime, commission, and share of network voting power before delegating. (shentu.org)

Regulatory & Compliance

Rules for CTK-related services depend on where and how they are offered. In the European Union, the Markets in Crypto-Assets framework sets authorization requirements for businesses providing covered crypto-asset services. In the United States, FinCEN guidance addresses certain businesses that transmit convertible virtual currency, while federal securities analysis considers the facts of a particular asset transaction and how it is offered. These frameworks address activities and service providers as well as the assets involved. (esma.europa.eu)

Shariah assessment likewise depends on the activity under review. CTK pays for network functions and supports proof-of-stake rewards, while ShentuShield has a separate structure for contributed funds and claims. An assessment of halal status would consider those arrangements—including how rewards are earned and how pool payments work—under Islamic finance principles concerning interest and uncertainty. The token’s security purpose is one part of that assessment, rather than a complete religious determination on its own. (shentu.org)

Future Outlook

Shentu’s development shows a continued interest in making verification usable on-chain. Its 2025 software release added OpenMath, and its May 2026 upgrade changed certificate handling and proof-related functions. Those changes build on the chain’s earlier emphasis on recording security knowledge and making it accessible to applications. (github.com)

The project’s direction will be shaped by whether developers make use of that infrastructure: requesting oracle findings, publishing useful certificates, running bounty programs, and building on verified proofs. Validators and CTK stakers also remain central because they produce blocks and take part in governance. Shentu’s long-term role therefore rests on both technical development and the everyday use of the tools built around it. (shentu.org)

Summary

Shentu is a Cosmos-based blockchain that puts security and verification at the center of its design. CTK pays chain fees, supports validator staking, and connects users to governance and security services. The Security Oracle, ShentuShield, OpenBounty, and OpenMath approach trust from different angles, giving the network a place in the wider effort to make blockchain software easier to assess and coordinate.
