How Does Shentu Work?

Decentralized Control

Shentu operates on a decentralized network of nodes distributed globally, free from control by any single entity.

These nodes collaborate to validate transactions and maintain the network's security, ensuring transparency and resilience while empowering users with greater autonomy.

Blockchain Core

Shentu's blockchain is a public, immutable digital ledger that records all transactions.

Transactions are grouped into blocks and linked through cryptographic hashes, forming a secure chain.

Anyone can view the records, establishing trust without intermediaries.

Shentu's unique security-oriented features, including its Security Oracle, provide real-time security metrics for audited networks.

Ensuring Fairness

Shentu employs a Delegated Proof-of-Stake (DPoS) consensus mechanism to validate transactions and prevent fraudulent activities.

Validators participate in network security by staking CTK tokens and running nodes, receiving rewards for their contributions.

Its innovations include a focus on security-first design and cross-chain compatibility.

Secure Transactions

Shentu uses public-private key cryptography to secure 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 pseudonymous transactions.

Additional security features include the CertiKShield, a decentralized reimbursement system for lost or stolen crypto assets due to security issues.
