Verifiable Finance is an on-chain financial architecture that combines zero-knowledge proofs (ZK) with Verifiable Computation. Its core goal is to improve the verification efficiency of complex financial systems without sacrificing transparency or decentralization. Compared with traditional on-chain finance, which mainly focuses on asset trading and liquidity management, Verifiable Finance places greater emphasis on whether the financial logic itself can be verified.

Nexus zkVM is the Zero-Knowledge Virtual Machine in the Nexus network. It is used to generate a corresponding zero-knowledge proof, or zk proof, after a program is executed, enabling verifiable computation. Unlike traditional virtual machines, which are only responsible for executing programs, zkVM can also prove that a program was executed according to its defined logic and allow other nodes to verify the result without rerunning the program.

Nexus (NEX) is a Layer 1 blockchain network built on zero-knowledge proof (ZK) technology and a zkVM architecture. It is designed to enable Verifiable Computation and Verifiable Finance. Through a modular proving network, distributed verification mechanism, and high-performance execution layer, Nexus allows complex computations to be verified on-chain at a lower cost.

Order book DEXs and AMMs are both widely used for on-chain asset trading, but they differ clearly in how prices are formed, how liquidity is structured, and how trades are executed. An order book DEX matches trades through buy and sell orders placed by users, while an AMM relies on liquidity pools and algorithms for automatic pricing.

dYdX (DYDX) is a decentralized derivatives protocol focused on perpetual contract trading. Through an independent appchain built on the Cosmos SDK, it provides users with a non-custodial, high-performance on-chain trading experience. Unlike traditional AMM-based DEXs, dYdX uses an order book model and off-chain matching mechanism, making it better suited to high-frequency trading and professional derivatives markets.

Perpetual contracts and traditional futures are both widely used for leveraged trading and risk hedging, so users often compare them side by side. Although both are derivatives contracts, they differ significantly in expiration mechanisms, price maintenance methods, and trading structures. Traditional futures have a fixed delivery date, and contracts are settled in cash or through physical delivery at expiration. Perpetual contracts, by contrast, have no expiration date and use a funding rate mechanism to keep the contract price close to the spot market price. As a result, perpetual contracts are generally better suited to continuous, high-frequency trading scenarios.

dYdX and Hyperliquid are both order book-based DEXs focused on on-chain perpetual futures trading, so they are often compared with each other. Although both emphasize a high-performance trading experience and low-latency matching, they differ significantly in their underlying chain structure, degree of decentralization, liquidity sources, and governance models. dYdX uses an appchain architecture built on the Cosmos SDK and secures its network through PoS validator nodes, while the DYDX token is used for both governance and staking. Hyperliquid, by contrast, uses a self-developed high-performance chain structure and places greater emphasis on ultra-low-latency trading and a unified liquidity experience.

Livepeer and Theta are both used for decentralized video infrastructure, but their core positioning is not the same. Livepeer focuses more on video transcoding, GPU-based video computation, and real-time AI video processing, while Theta places greater emphasis on video content distribution, edge node networks, and a decentralized CDN ecosystem.

Livepeer is a decentralized video and AI video infrastructure network. Its core operating mechanism includes video task distribution, GPU-based video transcoding, and on-chain incentive coordination. When a user uploads a video, the Gateway sends the task to an Orchestrator node, which then uses GPU resources to complete video transcoding or AI video processing.

Livepeer (LPT) is a decentralized video and real-time AI video infrastructure built on Ethereum. It is mainly used for video transcoding, live stream distribution, and AI video processing. The network provides GPU computing power through Orchestrator nodes and uses the LPT token to coordinate node incentives, staking, and network security.

Theta EdgeCloud is a hybrid AI edge computing platform launched by Theta Network. It coordinates distributed Edge Nodes and cloud GPU resources to process AI inference, video rendering, and other computing tasks. After developers submit a task, the system allocates it to global nodes based on resource requirements, while TFUEL is used for resource payments and node rewards. Compared with traditional centralized AI cloud platforms, Theta EdgeCloud places greater emphasis on distributed GPU sharing, edge computing, and efficient resource utilization.

Theta Network uses a layered node system made up of three core roles: Validator Node, Guardian Node, and Edge Node. Validator Nodes are responsible for block production and main chain validation, Guardian Nodes provide consensus oversight and network security, while Edge Nodes handle edge tasks such as video delivery, AI inference, and GPU computing. Through multi-layer node collaboration, Theta aims to support blockchain security, decentralized governance, and AI edge computing capacity at the same time.

Theta Network (THETA) is a decentralized blockchain infrastructure built for AI, video streaming, and edge computing. Through globally distributed nodes that share bandwidth and GPU resources, it provides low-cost, highly scalable network support for video delivery, AI inference, and Web3 media applications. Its ecosystem uses a dual-token model with THETA and TFUEL, where THETA is used for governance and staking, while TFUEL is used to pay for network resources and transaction fees. As generative AI and decentralized infrastructure continue to develop, Theta has gradually expanded into EdgeCloud, GPU computing, NFTs, Web3 entertainment, and several other areas.

THETA and TFUEL are the two core tokens in the Theta Network ecosystem, but they do not serve the same function. THETA is mainly used for governance, node staking, and network security, while TFUEL is used to pay for gas, AI computation, video processing, node rewards, and other network resource consumption. Theta’s dual-token mechanism is designed to separate governance from network operations, improving ecosystem efficiency while supporting the growth of edge computing and AI infrastructure.

XDPoS, short for XinFin Delegated Proof of Stake, is the consensus mechanism used by XDC Network. It secures the network and confirms transactions through validator staking, delegated voting, and Byzantine Fault Tolerance, BFT. Compared with traditional PoW networks, XDPoS uses less energy, processes transactions faster, and keeps Gas costs lower. It is mainly designed for high efficiency blockchain use cases such as enterprise finance, cross border payments, and real world assets, RWA. XDPoS also balances EVM compatibility with enterprise grade performance needs, making it an important part of XDC Network’s technical architecture.
