XION Learning Series: Tech Stack

Prioritizing dependability, flexibility, security, speed & community.

The purpose of XION is to revolutionize Web3 adoption by addressing the functional and cultural barriers that have hindered its widespread acceptance. By focusing on user experience, accessibility, and scalability, XION aims to create an ecosystem that empowers developers and users alike, unlocking the full potential of blockchain technology.

The technological foundation on which these user applications and experiences can be built requires careful thought and consideration. Here we delve into why the dependability, flexibility, and community of Cosmos contributed to our decision to build a sovereign L1 utilizing its SDK, and how it enables XION to be uniquely purpose-built for wide consumer adoption.

Dependability & Security

XION is built on the industry's most dependable and secure consensus framework (Comet BFT), inter-chain communication protocol (IBC), and developer toolkit (Cosmos SDK). This battle-tested infrastructure secures over $50 billion in assets, supports millions of transactions, and has stayed steady in extreme market turbulence. It is also trusted by some of the industry’s biggest projects, such as the Binance Chain (BNB), (CRO), Injective (INJ), and DyDx (DYDX) recently transitioning to its own standalone network.

The Inter-Blockchain Communication (IBC) protocol employed by XION is objectively the industry's most secure, permissionless cross-chain communication protocol. It allows any combination of blockchains to exchange data and value between them, and serves as a cornerstone to XION’s interconnectedness. In addition, the Comet BFT consensus framework allows XION to boast instant finality, fast confirmation times, and high throughput.

While building a platform not only for technologists but also for end users, our top priorities are defending the safety of XION users’ assets while still ensuring the availability of our products. Cosmos SDK-enabled chains have shown to be industry leaders for these metrics.

Flexibility & Development Speed

The Burnt team, the core contributors to XION, realizes the success of the network will not be defined solely by the team, but by those building on top of it. Much in the same way, the Cosmos SDK doesn’t make assumptions for developers but instead provides suggested defaults and options that developers can choose to use, expand, modify, or omit.

XION makes full use of this modularity. It is this modularity that allows XION to be a chain purpose built for consumer adoption, while still remaining interoperable across the entire industry. Through its unique implementation of core modules combined with its own custom-built ones, XION offers developers a robust and comprehensive toolkit upon which to build the next generation of retail-facing apps.

This modularity has other added benefits as well. For example, while we don’t necessarily know what the future holds – or what audiences will demand a week, month, or year from now – we are well positioned to react quickly. The Cosmos SDK, with its modular components and integrations, puts XION in a strong position to remain agile and flexible within a fast-shifting landscape.


The value of the Cosmos community is two-fold.

First, the quality of the engineering talent that has gone into the Cosmos SDK is second to none. We have already received help from and provided help to multiple teams, and wholly embrace the “rising tide lifts all boats” mentality. Cosmos has shown time and again its ability to produce groundbreaking technology that is later adopted by other industry participants. 

Second, the IBC framework allows us to rapidly incorporate other app chains and their associated features. For example, if a product calls for a private user state, we can connect to the Secret network. For DeFi, we have the Injective and Osmosis chains. For fiat and non-cosmos assets, we have the Axelar and Noble networks, etc. This community of interconnected chains allows us to make additional features available instantly to our audiences, and paves the way for developers on XION to usher in a new era of adoption through the plethora of new use-cases unlocked.

Our community-oriented ideals permeate all levels of our organization, not only because we are idealists, but because we believe it gives us a competitive advantage. We look forward to working collaboratively with blockchain developers, traditional developers, businesses, and all users (both crypto-native and mentally stable) to propel Web3 into the mainstream.
