Blockchains Built on Cosmos: An Introduction

In recent years, the blockchain space has exploded with new projects and technologies. One of the most exciting of these is Cosmos, an ecosystem of blockchains that can communicate with each other through the use of IBC (Inter-Blockchain Communication) technology. In this blog post by Flagship, we’ll explore what Cosmos is, how it works, and some of the most interesting blockchains built on the Cosmos ecosystem.

What is Cosmos?

Cosmos is a decentralized network of independent blockchains, each of which can have its own unique characteristics and governance structures. These blockchains can communicate with each other through the use of IBC, which enables them to exchange tokens and data without the need for a centralized exchange or intermediary. Cosmos is designed to be a scalable and interoperable platform for the development of decentralized applications (dApps).

How does Cosmos work?

At the core of the Cosmos network is the Cosmos Hub, which acts as a hub for all the other connected blockchains. The Hub uses a consensus algorithm called Tendermint, which allows for fast and secure transaction processing. Each connected blockchain has its own set of validators, who are responsible for confirming transactions and maintaining the network’s security.

One of the key features of Cosmos is the IBC protocol, which enables blockchains to communicate with each other. Through IBC, blockchains can send and receive data and tokens, which allows for the creation of complex decentralized applications that span multiple chains. This interoperability is one of the most compelling aspects of Cosmos, as it enables developers to build applications that leverage the strengths of multiple blockchains.

Blockchains built on Cosmos

Since its launch, Cosmos has become a popular platform for the development of new blockchain projects. Here are a few of the most interesting blockchains built on the Cosmos ecosystem:

  1. Binance Smart Chain (BSC): Binance Smart Chain is a high-performance blockchain built on the Cosmos ecosystem. It is designed to be compatible with the Ethereum Virtual Machine (EVM), which means that developers can easily port their Ethereum dApps to BSC. BSC has become a popular alternative to Ethereum due to its low transaction fees and fast confirmation times.
  2. Terra: Terra is a stablecoin-focused blockchain that uses algorithmic stablecoins to maintain price stability. The Terra blockchain is built on the Cosmos ecosystem and leverages the IBC protocol to enable the seamless exchange of Terra stablecoins with other cryptocurrencies.
  3. Akash Network: Akash Network is a decentralized cloud computing platform that is built on the Cosmos ecosystem. It enables developers to rent out unused computing power from around the world, creating a global network of cloud computing resources that is more efficient and cost-effective than centralized cloud providers.


Cosmos is an exciting new ecosystem that is enabling the development of a wide range of decentralized applications. Its interoperability and scalability make it an attractive platform for developers looking to build complex applications that span multiple blockchains. With the growing number of blockchains being built on the Cosmos ecosystem, it’s clear that this technology is here to stay.
