DFINITY developed the Internet Computer (ICP) blockchain and the blockchain has introduced several distinctive features that set it apart from other blockchains. In this article, we’ll take a look at each of these features.

1. Decentralized Hosting of Web Services: For a long time, applications have relied on centralized web hosting servers owned by companies like Amazon Web Services (AWS), Azure, etc. However, ICP enables decentralized hosting of web services and applications directly on its blockchain, thus enabling decentralized hosting of web services. Unlike traditional blockchains focused on transactions and smart contracts, ICP aims to function as a platform for hosting internet-scale applications independently of centralized servers or cloud services.

2. Chain Key Technology for Scalability: ICP implements Chain Key Technology to achieve horizontal scalability. Chain Key Cryptography comprises cryptographic protocols that coordinate the activities of nodes within the ICP network. This technology enables the IC to scale to millions of nodes while upholding robust security and operational efficiency. This innovative approach partitions the blockchain into multiple chains (subnets), allowing independent processing of transactions and smart contracts. By doing so, ICP enhances scalability and performance, potentially achieving high throughput and low latency for various applications.

3. WebAssembly (Wasm) Smart Contracts: WebAssembly (Wasm) Smart Contracts on the ICP blockchain represent a modern approach to executing decentralized applications (dApps). Smart contracts on ICP are coded in WebAssembly (Wasm), a versatile binary instruction format. Wasm enables efficient code execution on the blockchain and supports a diverse array of programming languages. This differs from Ethereum's Solidity and other blockchain platforms that utilize their own specific smart contract languages.

4. Canisters for Modular Applications: ICP introduced "canisters" as an alternative to traditional smart contracts. These are secure software units capable of interconnection to create modular applications. Canisters offer isolation and robust security guarantees, enabling developers to construct complex applications where different canisters communicate and interact seamlessly with each other.

5. Internet-Scale Applications: ICP aims to host Internet-scale applications directly on its blockchain infrastructure. This encompasses decentralized versions of social media platforms, financial services, and more, all operating natively on the blockchain. This approach differs from other blockchains that often rely on additional layers or off-chain solutions to achieve comparable capabilities.

In summary, the Internet Computer (ICP) blockchain distinguishes itself with its emphasis on decentralized web hosting, innovative scalability through Chain Key Technology, adoption of WebAssembly for smart contracts, introduction of modular canisters for application development, and direct support for internet-scale applications on the blockchain. These unique features set ICP apart from traditional blockchains and underscore its potential to drive forward a new era of decentralized applications and services.
