Web3 Infrastructure Market Projected to Reach $12 Billion by 2028 As Web3 technology establishes itself at the heart of the digital revolution, the core infrastructure supporting this ecosystem is experiencing rapid growth. Just a few years ago, Web3 infrastructure received little attention from investors and developers, but it has now emerged as a key topic in the global tech and finance industries. With the growth of decentralized applications (dApps), infrastructure platforms have become essential services across various domains, including data indexing, node hosting, storage, and identity management. According to a report by MEXC News via Techbullion, citing Messari's analysis, the Web3 infrastructure market, valued at approximately $2.5 billion in 2024, is projected to reach $12 billion by 2028. This signifies nearly a fivefold growth in just four years, clearly demonstrating that Web3 technology is not merely a fleeting trend but a foundational technology fundamentally transforming industrial structures. This rapid market expansion is a result of the popularization of blockchain technology, coupled with active corporate investments and the emergence of practical applications. Leading companies like Alchemy and Infura are considered pioneers in the Web3 infrastructure market. Notably, Alchemy processed over 300 billion API requests as of 2024, an almost sixfold increase compared to 50 billion requests in 2021. This remarkable growth clearly illustrates how rapidly data flow and development activities for blockchain-based applications are expanding. Alchemy provides API services that allow developers easy access to various blockchain networks, including Ethereum, significantly reducing the burden of complex blockchain infrastructure management. Developers can build and deploy blockchain applications instantly through Alchemy's infrastructure without the need to operate or maintain their own nodes. Infura, owned by ConsenSys, also plays a pivotal role in the Web3 infrastructure ecosystem. Infura provides stable API access to Ethereum and IPFS (InterPlanetary File System), enabling countless dApps worldwide to operate smoothly. Major Web3 wallet services like MetaMask also rely on Infura's infrastructure, proving that Web3 infrastructure platforms are not just backend services but crucial components ensuring the reliability of the entire ecosystem. The Graph holds a unique position in blockchain-based data indexing. The Graph processes over 3 billion data queries per month across 50 blockchain networks, significantly enhancing developer efficiency. Without indexing services, developers would have to go through the cumbersome process of scanning an entire blockchain from start to finish to retrieve specific data. This task is highly inefficient, potentially taking hours or even days. However, The Graph shortens this data retrieval time to milliseconds, allowing developers to access necessary information quickly and accurately. This is considered a crucial factor in rapidly accelerating the pace of the digital economy. Delving deeper into The Graph's operating principle, the protocol uses the concept of 'subgraphs' to organize and index specific blockchain data. Developers can query desired data using GraphQL, which operates similarly to traditional database queries. The key difference, however, is that the data is managed and verified on a decentralized network. This allows The Graph to ensure fast and reliable access to blockchain data while maintaining the principles of decentralization. The advancement of oracle networks is also remarkable. Chainlink is responsible for connecting on-chain (data on the blockchain) and off-chain (external data), significantly increasing the reliability and versatility of smart contracts. The value secured by DeFi (decentralized finance) protocols through Chainlink has exceeded $20 billion. This underscores the high accuracy and reliability of the data provided by Chainlink. The Impact of Web3-based Technology on Korea Chainlink provides various types of real-world data to blockchains, including price feeds, weather information, and Verifiable Random Functions (VRF) for smart contracts. For instance, DeFi lending platforms receive real-time cryptocurrency price information via Chainlink to accurately assess collateral value and determine liquidation thresholds. If unreliable price data were used, the entire system would be at risk of manipulation or malfunction. Chainlink eliminates such risks, thereby building a bridge for blockchains to securely connect with the real economy. Furthermore, Chainlink's oracle network does not merely provide price data. It is utilized in various fields, such as automatic insurance payouts based on weather data in insurance products, implementing transparent probability systems through fair random number generation in games, and integrating real-time logistics data in supply chain management. These application cases demonstrate that blockcha
