The internet is evolving. As we transition from centralized platforms to a more open, decentralized digital ecosystem, new infrastructures are required to bridge the gap between Web2 and Web3. Enter NEAR BOS — the Blockchain Operating System by NEAR Protocol — a groundbreaking framework designed to simplify and accelerate the adoption of the Open Web.
Launched in 2023, BOS (Blockchain Operating System) reimagines how users and developers interact with decentralized applications (dApps). By abstracting the complexity of blockchain technology, BOS delivers a seamless, composable, and user-friendly experience that brings Web3 closer to mainstream accessibility.
What Is the Open Web?
The Open Web refers to a decentralized internet — one that belongs to no single entity and is governed collectively by its users. It’s an internet built on principles of transparency, permissionless innovation, and user sovereignty.
Why does this matter?
- It enables free expression without censorship.
- It empowers individuals to own their data and digital identities.
- It fosters inclusive innovation, allowing anyone to build and contribute.
From day one, NEAR Protocol has been committed to making the Open Web a reality. To achieve this, they developed a scalable Layer-1 blockchain powered by Nightshade sharding, which enables high throughput and low transaction fees. But infrastructure alone isn’t enough.

To truly onboard the next billion users, NEAR needed a layer that simplifies discovery, interaction, and development across blockchains — which is where BOS comes in.
How BOS Enables the Open Web
Think of your smartphone’s operating system. It hides complex hardware processes behind a simple interface, letting you use apps effortlessly. Similarly, BOS acts as an OS for Web3, allowing users to discover, interact with, and build decentralized applications without needing technical expertise.
As Illia Polushkin, co-founder of NEAR Protocol, explains:
“BOS is a common layer for browsing and discovering Web3 products. It supports both NEAR and EVM-compatible chains, enabling cross-chain interoperability from day one.”
This means developers can launch a DeFi app on Ethereum and instantly reach users on NEAR — all through a unified frontend powered by BOS.
The Power of Composable Frontends
One of the biggest challenges in Web3 is fragmentation. While smart contracts are decentralized, most dApp frontends are hosted on centralized servers — creating single points of failure and censorship risks.
BOS solves this by enabling composable, decentralized frontends. These frontends:
- Are stored on-chain (primarily on NEAR due to low storage costs).
- Can be forked, modified, or combined like open-source code.
- Work with any backend — Web2 or Web3 — and any wallet.
Polushkin envisions a future where:
“You can use your wallet from one chain to interact seamlessly with another via bridging — all through decentralized interfaces.”
This composability unlocks unprecedented agility for developers and trust for users.
The Three Pillars of BOS
BOS is built on three foundational components that work together to create a robust Web3 experience.
1. Gateways
Gateways are decentralized nodes that host and serve frontend code. They run a specialized virtual machine capable of rendering applications built on NEAR, Ethereum, and other EVM-compatible chains.
Because frontends are loaded locally from the NEAR blockchain, gateways eliminate reliance on centralized hosting providers. This ensures censorship resistance and high availability.
2. Components
Components are reusable frontend modules — think of them as Lego blocks for building dApps. Examples include widgets for DeFi protocols like Uniswap or Lido.
Developers can:
- View component source code directly in a gateway (similar to Etherscan).
- Fork existing components.
- Combine multiple components into new applications.
This modularity accelerates development and encourages innovation through collaboration.
3. Blockchains
BOS supports multiple blockchains, including all EVM chains and NEAR. Components can call smart contract functions across chains, enabling true cross-chain interoperability.
Crucially, frontend code is stored on NEAR because it offers low-cost storage for HTML, CSS, and JavaScript — a key advantage over other blockchains.
Exploring BOS: A Hands-On Look
Want to see BOS in action? Visit alpha.near.org — the live demo environment for BOS.
Once there:
- Hover over “Discover” in the navigation bar.
- Click “Components” to browse available modules.
Each component serves a specific function and can be embedded or customized. Let’s look at some core built-in components:
Widget
The smallest unit in BOS. A widget embeds a component into your application.
const user = "gagdiez.near";
const props = { name: "Learn NEAR" };
return (
<>
<Widgets src={`{user}/widget/hello-world`} props={props} />
</>
);This allows developers to compose complex interfaces from simple, trusted building blocks.
Image Uploader
Enables direct upload to IPFS (InterPlanetary File System), ensuring decentralized storage.
State.init({ img: null });
return (
<FileUpload onChange={(file) => uploadToIPFS(file)} />
);Users retain full control over their media — no centralized servers involved.
Markdown Renderer
Renders Markdown content securely within the BOS environment.
const text = "## Welcome to BOS\nCheck out [Learn NEAR](https://learnnear.club/)";
return <Markdown>{text}</Markdown>;Perfect for documentation, blogs, or dynamic content displays.
OverlayTrigger & Tooltip
Enhance UX with interactive elements like hover tooltips.
<OverlayTrigger placement="top" overlay={<Tooltip>Click me!</Tooltip>}>
<button>Hover</button>
</OverlayTrigger>These components improve usability without sacrificing decentralization.
InfiniteScroll & Typeahead
Enable smooth user experiences with lazy-loaded content and autocomplete features — all while maintaining full decentralization.

Why BOS Matters for Web3 Adoption
BOS addresses four critical challenges in Web3:
- Access: Simplifies discovery and usage of dApps.
- Security: Eliminates reliance on centralized frontends.
- Composability: Lets developers build faster using shared components.
- Agility: Supports cross-chain interaction out of the box.
By running frontends locally and storing them on-chain, BOS ensures applications remain functional even under censorship or server outages.
Frequently Asked Questions (FAQ)
Q: What is the main purpose of NEAR BOS?
A: BOS simplifies Web3 interaction by providing a decentralized, composable operating system for browsing and building dApps across multiple blockchains.
Q: Can I use BOS with non-NEAR blockchains?
A: Yes. BOS supports all EVM-compatible chains (like Ethereum and Polygon) alongside NEAR, enabling true cross-chain compatibility.
Q: How are frontends stored in BOS?
A: Frontend code is stored on the NEAR blockchain, leveraging its low-cost data storage for HTML, CSS, and JavaScript files.
Q: What is a "widget" in BOS?
A: A widget is the smallest reusable unit in BOS — essentially a component that can be embedded into other applications to create complex interfaces.
Q: Are BOS components open source?
A: Yes. All components are publicly viewable, forkable, and composable, promoting transparency and collaborative development.
