# 2. Why Blockchain? Although Datagram serves both Web2 and Web3 businesses, its advantages over legacy systems come from its being built using blockchain technology. Web2 has historically relied solely on centralized systems, which have been satisfactory for traditional business functions but at the same time subject to inherent limitations that have proven difficult to address, including: * **Single Points of Failure:** Centralized servers and databases create vulnerabilities; if they go offline, the entire system can become inaccessible. For example, AWS experienced a major outage in December 2021, taking down services like Netflix, Disney+, Robinhood, and Slack. * **Lack of Economic Alignment:** Traditional systems do not provide economic incentives for users to contribute resources, participate in governance, share bandwidth, or profit from the system’s success. * **High Costs:** Centralized systems require multiple intermediaries, licensing fees, and redundant infrastructure to handle peak demand, leading to excessive operational overhead. Servers must also remain powered on at all times to accommodate potential high-load periods, resulting in unnecessary energy consumption and inflated costs for businesses and users. * **Privacy, Data Ownership & Security Risks:** Users have little control over their data, which is often stored on centralized servers and is vulnerable to hacking, breaches, and surveillance. This data is frequently misused, stolen, or sold without user consent. * **Restricted Innovation & Control:** Only the entity that owns the system can implement changes, while open innovation or user-driven improvements are infeasible. Other limitations include censorship and deplatforming risks, geographic and jurisdictional limitations, and vendor lock-ins. Fortunately, blockchain’s decentralized architecture addresses all of these concerns, while complex operations can be automated through smart contracts and the entire system can be tailored to specific needs and detailed use cases. At a fundamental level, blockchain offers several key advantages that set it apart from traditional centralized systems: * **Decentralized Consensus & Fault Tolerance:** Unlike centralized architectures, where downtime affects the entire system, blockchain-based networks rely on independent validators reaching consensus, ensuring continuity even if individual nodes fail. * **Smart Contract Automation:** Smart contracts enforce rules transparently and immutably, reducing the need for external trust while enabling auditable, on-chain decision-making. For example, payments, resource allocation, data transmission, and more can all be automated via smart contracts. * **Efficient Data Propagation:** Distributed architectures leverage peer-to-peer networking, reducing latency and improving resilience compared to centralized cloud providers that suffer from congestion and regional outages. * **On-Chain Incentives:** Instead of provisioning fixed infrastructure, blockchain enables dynamic scaling where validators, storage providers, and bandwidth contributors are economically rewarded for their participation. Datagram has integrated these principles from the ground up, building a next-generation decentralized connectivity infrastructure that combines blockchain’s advantages with real-world scalability, interoperability, and ease of use. Designed by a team of industry veterans, Datagram leverages Avalanche’s high-performance Layer 1 architecture while maintaining blockchain-agnostic interoperability across multiple networks. This ensures a robust, distributed network where businesses retain full control over their data, benefit from censorship-resistant infrastructure, and scale seamlessly without the inefficiencies of legacy systems. Datagram is the ultimate solution to real-world adoption of Web3, providing enterprises, developers, and service providers Providers with a powerful foundation to launch and scale applications effortlessly. --- # 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.
