What is Cubechain (QUB)?
Cubechain (QUB) is a blockchain platform designed to provide rapid speed, robust security, and scalability. Unlike traditional blockchains that use a linear arrangement of blocks, Cubechain is built on a "cube" structure. Each cube is composed of 24 data blocks and three specialized blocks: an indexing block, a statistics block, and an escrow block. This architecture allows for parallel data processing, which contributes to faster transaction speeds. The specialized blocks within the cube facilitate quick data analysis, efficient searching, and scalable payment services. To enhance security, Cubechain incorporates multiple hash functions, including SHA 256, CH-S1, CHF, and SHA 384. The platform has reported high transaction processing capabilities, with its testnet achieving over 10,000 transactions per second (TPS) and its mainnet exceeding 7,000 TPS. This high performance aims to make Cubechain suitable for applications requiring immediate processing, such as those in fintech. Cubechain utilizes a Proof of Hybrid (PoH) consensus algorithm, combining aspects of Proof of Work and Proof of Stake. The project's vision is to serve as a versatile blockchain service platform, with a particular focus on the e-commerce industry. Its ecosystem includes services like CubeON, a blockchain-based social network, CubeChat, a peer-to-peer transaction messenger, and an AI Service Manager (ASM). Cubechain 2.0 has expanded its offerings to include features such as a messenger and online shopping functionalities. Additionally, Cube Scan acts as an explorer that allows users to view and verify transactions on the Cubechain network. Learn more

Cubechain (QUB) FAQ
Cubechain (QUB) aims to transform the e-commerce industry by creating an "omnidirectional" system that moves beyond traditional frameworks dominated by intermediaries. Its core vision is to build a shared economy, distributing profits equitably through its native QUB token. The project positions itself as a platform coin, leveraging blockchain technology to construct a comprehensive cryptocurrency ecosystem that benefits all participants.
Cubechain addresses critical issues in large markets and direct peer-to-peer transactions. These include the widespread problem of fake transactions and the absence of standardized trading and security systems that adequately protect users. Additionally, the project aims to overcome inefficiencies and high costs associated with traditional customer service operations by implementing AI-driven solutions, enhancing overall operational effectiveness and user trust.
Unlike conventional blockchains with linear block connections, Cubechain utilizes a distinctive "cube" concept. This design extends database functionalities, allowing for three-dimensional implementation and multiplexing of blocks. This innovative architecture enables enhanced data processing velocity through parallel processing. For consensus, Cubechain employs a hybrid mechanism combining Proof-of-Work (POW) and Proof-of-Stake (POS), ensuring network security and integrity while optimizing transaction throughput.
Cubechain offers several key services. SignOne provides a blockchain-based login authentication platform to enhance security and simplify user access. Cube Chain Product stores product information and transaction history on the blockchain, enabling certified product data and a marketplace. CubeChat is an AI-Chatbot improving customer service efficiency, reducing costs, and rewarding users with QUB tokens. The ASM (AI Service Manager) further integrates AI-Chatbot, Big Data, and Cubechain for real-time responses and efficient task handling.
The total supply of Cubechain (QUB) tokens is fixed at 12 billion. A significant portion, 80% (9.6 billion QUB), is allocated for open mining activities. The remaining 20% was generated with the Genesis block. This portion is distributed among pre-sale and crowdfunding participants (10%), for initial business model establishment (5%), and for platform maintenance and team members (3%). This structure aims to balance community participation through mining with foundational development and operational needs.
To participate in Cubechain's Proof-of-Stake (POS) mechanism, users must hold a minimum of 5,000 QUB tokens. Participants receive compensation proportionate to their QUB holdings, based on previously validated blocks, acting as a reward for securing the network. It's important to note that QUB tokens staked for POS participation are temporarily unavailable for transfer, ensuring their commitment to the network's stability and consensus process.
