 :::faq[How does aelf compare to other blockchain platforms in terms of transaction speed and scalability?]
 
 aelf stands out in the blockchain landscape with its exceptional transaction speed and scalability. Its multi-sidechain architecture enables parallel processing of transactions, significantly enhancing both speed and scalability compared to traditional single-chain systems. In terms of benchmarking, aelf consistently performs favourably against other leading blockchain platforms in transaction throughput and network efficiency. Additionally, aelf integrates artificial intelligence (AI) to optimise various aspects of its operations, including smart contract execution and network management, which further boosts its performance and scalability. This combination of multi-sidechain architecture, advanced Layer 2 solutions, and AI integration positions aelf as a superior choice in the blockchain arena.

 :::faq[What is the difference between aelf's MainChain and SideChains?]
 
 aelf's MainChain and SideChains serve distinct but complementary roles within its blockchain architecture. The MainChain acts as the backbone of the network, responsible for overall governance, security, and coordination. It manages cross-chain interactions and ensures the integrity of the entire ecosystem. SideChains, on the other hand, are specialised chains that handle specific types of transactions or applications. They operate independently but are connected to the MainChain, allowing for parallel processing of transactions. This design significantly enhances scalability by distributing the workload across multiple SideChains, reducing congestion and improving performance. Each SideChain can be customised for different use cases, providing flexibility and efficiency in handling diverse applications.
