Qitmeer Network: A High-Performance Public Blockchain Based on BlockDAG
Qitmeer Network is an innovative project aimed at solving the blockchain “trilemma” — achieving network growth without compromising security and decentralization. To achieve this, the network uses the MeerDAG protocol, a Directed Acyclic Graph (DAG)-based consensus mechanism that offers a new approach to Layer 1 blockchain scaling. By processing transactions in parallel and optimizing data structures, MeerDAG effectively reduces the performance problems of traditional blockchains while ensuring ledger consistency and immutability.
Traditional blockchain architectures often struggle to balance decentralization, security, and efficient growth, leading to the so-called “trilemma”. Qitmeer Network, through the MeerDAG protocol, explores a new path to balance performance, decentralization, and security. The design of MeerDAG supports parallel processing across multiple chains, avoiding the main chain contention issues found in traditional blockchains, theoretically allowing for higher speed and shorter transaction confirmation times.
To further improve network performance and scalability, Qitmeer Network also adopts a layered architecture (Layer 1 + Layer 2) and cross-chain interoperability solutions. The layered architecture combines the core consensus layer (Layer 1) with the scalability improvement layer (Layer 2), ensuring the security and decentralization of the base layer while achieving efficient transaction processing and network scaling through Layer 2. The cross-chain interoperability solutions further strengthen Qitmeer Network’s ability to operate across different blockchains, making it adaptable to a wider range of use cases and user demands.
MeerDAG Consensus Protocol: Addressing Layer 1 Data Scalability
Qitmeer Network’s MeerDAG protocol differs from traditional chain-based blockchain structures by using a graph-based ledger protocol built on a generalized Nakamoto consensus. It combines the advantages of GHOSTDAG and SPECTRE, improving performance and addressing transaction ordering issues in DAG networks. MeerDAG analyzes the connectivity between blocks to identify the largest subset of honest nodes, ordering blocks in strict topological sequence, thus ensuring transaction consistency and reliability.
Additionally, MeerDAG supports asynchronous bookkeeping, allowing users to initiate transactions without waiting for prior on-chain confirmations. Instead, they perform simple local verification and broadcast to the entire network, greatly speeding up transaction processing.
MeerEVM: Enhancing Smart Contract Execution
An important part of Qitmeer Network, MeerEVM is a high-efficiency smart contract execution engine powered by the MeerDAG protocol. This engine is compatible with the Ethereum Virtual Machine (EVM), providing developers with a smooth environment to migrate their DApps, thereby expanding Qitmeer Network’s ecosystem.
Meerlink Protocol: Boosting Blockchain Integration
Meerlink Protocol is a unique Layer 1 cross-chain interaction protocol. Through a transaction synchronization consensus mechanism, it ensures the state synchronization of contract transactions over different networks, allowing efficient asset transfers. This protocol opens up new possibilities for blockchain interoperability, driving the growth of the entire blockchain ecosystem.
Layer 1 + Layer 2: Building a Comprehensive Blockchain Ecosystem
Qitmeer Network is a high-performance public blockchain, with its technical architecture based on the revolutionary MeerDAG unity protocol. The network adopts a Layer 1 + Layer 2 structure, and its BlockDAG unity protocol, which is the core engine, drives the efficient operation of a pluggable smart contract execution engine. The container layer connects the entire blockchain ecosystem, supporting seamless cross-chain smart contract interoperability.
Layer 1: Meer Network
Meer Network is the key infrastructure of Qitmeer Network, built on innovative BlockDAG technology and a UTXO data model, creating a PoW-based underlying blockchain. However, its true uniqueness is in developing the BlockDAG protocol into the MeerDAG consensus protocol. This protocol allows multiple transactions to be processed in parallel and confirmed without delay while maintaining the network’s decentralization and stability. The MeerDAG consensus protocol can be seen as the “core engine” of Qitmeer Network, promoting continuous development and innovation.
Cross-Chain Hub: QNG Network
MeerEVM is the core component of the QNG Network, powered by the MeerDAG protocol, providing developers with an efficient smart contract execution environment. This engine is suitable for high-concurrency scenarios such as GameFi, DeFi, and SocialFi, aiming to offer fast confirmation and high throughput experiences, thus promoting scalability and cross-chain interoperability.
Layer 2: Decentralized AI Network
Qitmeer Network’s decentralized AI network leverages advanced artificial intelligence to provide smart contracts with powerful data processing and analytical capabilities. By integrating AI at the Layer 2 level, smart contracts can complete more complex and intelligent tasks, such as automated decision-making, real-time data analysis, and predictive modeling. This boosts the execution efficiency of smart contracts and also greatly improves their range and applicability.
Qitmeer Network’s decentralized AI network represents a significant milestone in the combination of blockchain and artificial intelligence. This not just expands the capacity of smart contracts but also opens new opportunities for the general application of blockchain technology. This new vision is expected to bring a full change of the Qitmeer Network brand and potentially introduce exciting enhancements to the broader ecosystem.
