Description: What Does IoTeX Do?

IoTeX aims to build a decentralized network tailored for the IoT sector, focusing on enhancing scalability, privacy, and efficiency. The main objective is to create a network where IoT devices can operate autonomously and securely, mitigating the issues associated with centralized IoT systems.

To achieve these goals, IoTeX employs a "blockchains in blockchain" architecture, privacy-preserving techniques, and a fast consensus mechanism. This approach ensures that the network is scalable, cost-effective, and capable of supporting various IoT applications.

Problem: Why IoTeX Is Being Developed?

The development of IoTeX is driven by the need to address several critical issues in the current IoT landscape. Traditional IoT systems are typically centralized, leading to problems like scalability limitations, high operating costs, and significant privacy and security concerns. These issues affect a wide range of stakeholders, from individual users to large-scale industrial applications.

Existing solutions attempt to address these problems but often fall short due to the unique characteristics of IoT devices, such as their large quantity, heterogeneity, and constraints in computation, storage, and power. IoTeX aims to overcome these limitations by leveraging blockchain technology, which is inherently decentralized and can provide the necessary scalability, security, and privacy.

Use Cases

• Shared Economies: IoTeX can power decentralized shared economies, ensuring that deposits and user data are securely managed by smart contracts rather than centralized entities.
• Smart Home: By deploying IoT devices on the IoTeX blockchain, smart home manufacturers can reduce operating costs and improve device performance while ensuring data privacy and security.
• Identity Management: IoTeX enables decentralized identity and access management for IoT devices, ensuring secure communication and authentication.

How Does IoTeX Work?

IoTeX employs a multi-layer blockchain architecture to support a scalable and privacy-centric IoT network. It includes a root blockchain and multiple subchains that cater to different IoT applications. The root blockchain handles overall network security and cross-blockchain communication, while subchains are tailored for specific IoT use cases.

The operation of IoTeX can be broken down into the following steps:

1. Initialization: Subchains are registered on the root blockchain with their configurations and operators.
2. Transaction Initiation: IoT devices initiate transactions within their subchains.
3. Cross-Blockchain Communication: When needed, transactions are relayed to the root blockchain and then to other subchains.
4. Consensus Mechanism: The network uses a fast consensus mechanism called Roll-DPOS, combining DPoS, PBFT, and VRF to achieve instant block finality.
5. Execution and Finality: Transactions are validated, finalized, and added to the blockchain, ensuring secure and efficient operations.

Technical Details

IoTeX utilizes a blockchain architecture designed for scalability and privacy. The root blockchain follows a UTXO-based model, similar to Bitcoin, and employs privacy-preserving techniques like ring signatures and ZK-SNARKs. Subchains use an account-based model, supporting smart contracts and customized tokens.

Key technologies and methods include:

• Blockchains in Blockchain: A scalable architecture that separates duties between root and subchains.
• Privacy-Preserving Techniques: Stealth addresses, ring signatures, and bulletproofs for transaction privacy.
• Roll-DPOS Consensus: A combination of Delegated Proof of Stake (DPoS), Practical Byzantine Fault Tolerance (PBFT), and Verifiable Random Functions (VRF) for fast consensus.

IoTeX Tokenomics: Token Utility & Distribution

IoTeX's native token, IOTX, is an integral part of the ecosystem, designed to facilitate transactions and incentivize network participants.

Within the ecosystem, IOTX is used to execute transactions and run distributed applications, providing economic incentives for maintaining the network. The token is mineable for 50 years, with rewards reducing over time based on a linear gradient.

The token distribution strategy is designed to ensure sustainable network growth. IOTX tokens are initially issued as ERC20 tokens on the Ethereum blockchain, which will be migrated to the IoTeX mainnet upon its launch. The tokens do not represent any ownership or rights in the IoTeX Foundation.

Key IoTeX Characteristics

IoTeX aligns with core blockchain characteristics to address IoT-specific challenges:

• Decentralization: Utilizes a decentralized network to eliminate the need for centralized control.
• Anonymity and Privacy: Employs stealth addresses, ring signatures, and bulletproofs for transaction privacy.
• Security: Uses advanced cryptographic techniques to ensure data security.
• Transparency: Blockchain provides immutable and transparent records.
• Immutability: Ensures that once data is recorded on the blockchain, it cannot be altered.
• Scalability: "Blockchains in blockchain" architecture maximizes scalability.
• Supply Control: IOTX tokenomics include a controlled supply with a mineable period of 50 years.
• Interoperability: Supports cross-blockchain communication for IoT device coordination.
