Question 1

What is UChain?

Accepted Answer

UChain is a decentralized blockchain platform designed to provide a scalable, high-performance infrastructure for payments, decentralized applications (dApps), and digital asset management. The project’s mission is to create a truly open, accessible, and fast blockchain that can process over 2,000 transactions per second while maintaining low fees and strong decentralization.

The network offers developers the ability to issue tokens, create NFTs, and deploy smart contracts using Solidity, ensuring compatibility with existing Ethereum-based tools and projects. UChain operates on a Delegated Proof-of-Stake (DPoS) consensus mechanism that elects 27 Super Representatives (SRs) every six hours to validate blocks and maintain network integrity.

UChain’s blockchain architecture focuses on throughput, accessibility, and interoperability. It supports 60+ API gateways and a distributed data storage model designed for reliability and speed. Its infrastructure also powers multiple ecosystem products, including wallets, cards, and liquidity tools, making it suitable for everyday use and enterprise applications.

Question 2

What is the UChain Coin (UCN)?

Accepted Answer

UCN is the native utility coin of the UChain blockchain. It serves as the foundation for all transactions, payments, and network operations within the ecosystem.

**Network utility:** UCN is used to pay for transaction fees, energy, and bandwidth points that power smart contract execution.  
**Governance:** Holders can stake UCN to gain voting power (UPower) and participate in the election of Super Representatives, who help shape the network’s governance and proposals.  
**Incentives:** UCN is distributed as a reward to validators and voters participating in the DPoS consensus process.  
**Ecosystem integration:** UCN supports token issuance (URC-20) and NFT creation (URC-721) within the network and fuels products such as UWallet, UDefender, and UCard.  
**Deflationary mechanics:** The ecosystem employs hyper-deflationary strategies such as coin burns and halving cycles to maintain value stability and scarcity.

UCN is essential for maintaining bandwidth and energy resources in the network. Every transaction consumes bandwidth points, with 1,500 free points granted daily to each account, making basic use nearly cost-free.

Question 3

Technical architecture

Accepted Answer

UChain’s architecture combines speed, accessibility, and scalability to support both consumer and developer adoption.

- **Consensus:** Operates under DPoS with 27 elected SRs who generate blocks every 3 seconds.  
- **Performance:** Achieves over 2,000 transactions per second with near-zero latency.  
- **Compatibility:** Uses Solidity smart contracts, ensuring migration compatibility with Ethereum and other EVM-based systems.  
- **Resource models:** Employs both bandwidth and energy systems to allocate network resources efficiently.  
- **Data integrity:** Implements TaPoS (Transaction as Proof-of-Stake) for improved security and resistance to chain forgery.

The blockchain leverages Google Protocol Buffers for data structuring, ensuring high efficiency and interoperability. Nodes are categorized as Witness, Full, or Solidity nodes, each performing specialized roles in validation and data relay.

Question 4

The UChain ecosystem

Accepted Answer

The UChain ecosystem includes several interlinked products designed to expand adoption and utility:

- **UWallet:** A multi-asset wallet supporting UCN, BTC, ETH, TRX, and USDT, allowing users to manage up to 50 addresses from one mnemonic.  
- **UDefender:** A physical NFC cold wallet card that stores part of a user’s private key, providing enhanced security for signing transactions.  
- **UCard:** A crypto debit card supporting multiple cryptocurrencies and compatible with Apple Pay and Google Pay.  
- **Splitting technology:** A unique mechanism distributing rewards through decentralized liquidity pools that reward users who lock tokens to provide market liquidity.

The ecosystem’s value strategy includes a limited supply of UCN, automated halving events, and liquidity-based reward systems to sustain demand and long-term value growth.
