# What is X-Chain? Ideally, developers should be able to build any application on the X-Chain Network without having to consider its scalability. The X-Chain Network solves prominent industry issues, such as: * Scalability, * Interoperability and * Lack of developer incentives. Regarding scalability, it is important to note that blockchains are not scalable by design due to the decentralized consensus mechanism. This leads to a significantly lower transaction per second (TPS) compared to a centralized database, as well as an upper limit on the data that can be stored in each block. As a result, users may experience delays and long wait times for transaction confirmation, which negatively impacts the user experience. The X-Chain Network aims to address these issues by focusing on increasing TPS, reducing transaction costs, and providing faster finality. Interoperability is also a significant problem, as many blockchains exist and few have interoperability as a native feature. To transfer "value" from Bitcoin to Ethereum, a centralized exchange is required. The Ethereum is a shard protocol that allows blockchain networks to operate seamlessly together. The X-Chain Network is compatible with ERC-20, enabling true interoperability between them. Finally, the lack of incentives for developers is a major problem in the industry, as they represent the most important human resource in the blockchain industry. Developers face many costs in developing dApps or infrastructure projects. The X-Chain Network has a solution for this problem, with the #Build2Earn protocol that allows developers to earn a basic income while working on their projects. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
