Cosmos has become synonymous with the idea of interoperability in the crypto space. 

In an industry increasingly dominated by siloed projects either serving the same purpose with different selling points or offering unique services, Cosmos separates itself by focusing on connecting each project.


Touted as the “Internet of Blockchains” by its founders, the project promises to allow seamless communication between independent blockchain projects.

What is Cosmos (ATOM)? Why do we need an internet of blockchains, and how does it compare to other solutions?

What Is Cosmos (ATOM)?

Cosmos is a growing network of independent blockchains that can share data and assets in a decentralized manner.

The ecosystem connects popular projects like Binance’s BNB chain,’s Cronos, and the Terra Classic network.


Unlike other Layer-1 networks like Ethereum, which play host to multiple applications on a single layer, Cosmos provides these applications with the tools to build their own sovereign blockchains that are interoperable with the rest of the ecosystem.

The benefits of interoperability and sovereignty include increased flexibility, scalability, and security. Cosmos (ATOM) enables developers to create more complex applications and services by allowing different blockchains to work together. Each blockchain’s sovereignty also ensures no single point of failure in the network, making it more secure and resilient.

How Cosmos Enables Developers to Build Application-Specific Blockchains

Cosmos offers developers several tools to streamline the process of creating blockchains for specific applications. These tools include:

Tendermint Core – Tendermint Core is the open-source software that secures the Cosmos ecosystem. The software runs on a proof-of-stake consensus algorithm, requiring nodes to stake the native crypto asset to validate transactions on the network.

Tendermint’s PoS algorithm is Byzantine Fault-tolerant (BFT), allowing for continued operations even if 33% of the nodes fail.

While it is the default consensus model for Cosmos blockchains, other consensus models can also be used.

Application BlockChain Interface (ACBI) – Unlike other blockchains, Cosmos separates its application layer from its consensus layer. The application layer is where developers create decentralized apps (DApps). The application layer on the Cosmos network is called the Application BlockChain Interface (ACBI).

The separation of the application layer from the consensus and networking layers allows developers the freedom to develop sovereign and application-specific blockchains. In contrast, on blockchains like Ethereum, developers can not separate their applications from the Ethereum mainnet.

The Cosmos SDK – Cosmos offers developers a software development kit (SDK) to make building blockchains on the application layer easier. With the open-source SDK, developers significantly save time and cost.

Why Is the Interoperability Offered by Cosmos Important?

The Web3 space is booming with multiple blockchains and blockchain layers. This rapid growth of different blockchain ecosystems comes from the desire to optimize for other use cases. For example, projects focused on gaming might desire more smart contracts and throughput capabilities than those focused on payments.

As the ecosystem becomes more varied, it becomes necessary for these separate blockchains with unique offerings to interoperate. This interoperability is particularly important for developing cross-chain applications and institutions looking to interact with multiple on-chain solutions. The problem, however, is that most blockchains lack inbuilt communication capabilities. 

While there have been attempts to solve this problem with things like swaps and bridges, these solutions have left much to be desired, posing a vulnerability in many instances. Cosmos proposes a unique solution to this problem.

How Does Cosmos Work?

Cosmos employs what it calls a hub and zone model. This design enables blockchains to maintain their sovereignty while enjoying the network’s interoperability.

Zones – A zone is an independent blockchain within the Cosmos network. Zones are sometimes referred to as application-specific blockchains.

Hubs – A hub is a blockchain that connects zones acting as a communication layer. The Cosmos Hub was the first blockchain in the Cosmos network and the first hub. Hubs are notably connected to Zones through Inter-Blockchain Communication channels.

Inter-Blockchain Communication (IBC) Protocol – The inter-blockchain communication protocol is the technology that makes communication between blockchains in the Cosmos network possible. IBC acts as a channel allowing the flow of data and tokens.

It is worth noting that there are also special blockchains that allow the Cosmos ecosystem to connect with external networks called peg zones. Cosmos developers are notably working on peg zones for Bitcoin and Ethereum.

What Role Does ATOM Play in the Cosmos Network?

ATOM is the native token of the Cosmos Hub and the broader ecosystem’s primary token. 

On the Cosmos Hub, ATOM is primarily used for staking and governance. At the same time, the cryptocurrency is key to the broader network’s interoperability due to its availability on central exchanges. 

ATOM’s role in the Cosmos ecosystem allows the asset to grow more valuable with each zone that joins the ecosystem. It is, however, worth noting that there is no limit to how many ATOM tokens can be created as new ATOMs are minted to reward validators.

Cosmos History & Founders 

Computer scientists Jae Kwon and Ethan Buchman founded Cosmos in 2014 with help from a Swiss blockchain-focused research and development company called the Interchain Foundation (ICF). Kwon and Buchman released the Cosmos white paper in 2016.

ICF held a two-week initial coin offering (ICO) for ATOM in 2017, raising $17 million in several rounds of funding led by Paradigm. 

Developers raised another $9 million in funding to continue development in 2019, announcing the news a day after releasing Cosmos Hub. 

Cosmos is notably not the only crypto project that has emphasized interoperability. Polkadot, another project that has staked its identity on interoperability, has often drawn comparisons with Cosmos. The same is true with Chainlink.

Cosmos v. Polkadot 

While Polkadot’s parachains appear similar to Cosmos’ zones, both ecosystems have different governance and token transfer approaches.

Cosmos allows each zone to have separate governance and validator structures. Polkadot parachains, on the other hand, share the same validator set.

At the same time, while zones can easily transfer tokens and data via IBC, parachains require smart contracts to transfer tokens and data, making them more vulnerable to exploits.

Cosmos and Chainlink are blockchains focused on interoperability. However, they have different goals and approaches.

While Cosmos aims to create a network of independent blockchains, Chainlink is built to connect smart contracts on different blockchains to real-world data. Cosmos uses IBC, while Chainlink works with decentralized oracles.

Cosmos and Chainlink have significantly different use cases as a result. While the former can be leveraged in decentralized finance (DeFi), gaming, and supply chain management, the latter primarily provides secure price feeds.

Pros and Cons of Cosmos (ATOM)

The Cosmos network most certainly has a lot of promise, but this innovation is not without its drawbacks.


  • Interoperability – Cosmos (ATOM) enables communication and data exchange between different blockchains, creating a network of interconnected blockchains.
  • Sovereignty – Each blockchain in the Cosmos network is independent and can have its own set of rules and governance structures, ensuring no single point of failure in the network.
  • Scalability – Cosmos (ATOM) is highly scalable, with the ability to process thousands of transactions per second.
  • Customization – Developers can customize their blockchains in the Cosmos network to meet their specific needs and requirements.
  • Security – The Cosmos network is highly secure, with a robust consensus mechanism. 


  • Complexity – The Cosmos ecosystem is complex and can be difficult for non-technical users to understand.
  • Competition – There are other projects in the blockchain interoperability space, such as Polkadot are also competing for market share.
  • Volatility – The cryptocurrency market is highly volatile, and the value of ATOM can fluctuate rapidly.
  • Adoption – The success of Cosmos (ATOM) depends on the adoption of the network by developers and businesses, which is not guaranteed.
  • Regulation – The regulatory environment for cryptocurrencies and blockchain technology is still evolving, which could impact the future of the Cosmos network.

On the Flipside 

  • Despite its advantages, Cosmos has fallen in popularity compared to competitors like Chainlink and Polkadot.
  • Peg zones connecting Cosmos to popular projects like Bitcoin and Ethereum are yet to roll out.

Why This Matters 

New blockchain projects spring up nearly every day, offering unique perks to users. However, if Web3 is to become more than just a buzzword heralded by crypto enthusiasts, then these different networks need to be able to communicate. This need for interoperability makes solutions like Cosmos critical to the vision of Web3.


Is Cosmos a good investment?

Cosmos (ATOM) has the potential to grow more valuable as new zones join the network. However, it is worth noting that the coin is inflationary, as there is no limit to its supply.

Will Cosmos reach $1,000?

If Cosmos’ ATOM reached the $1,000 price, it would have a market cap of $292.6 billion. Cosmos would flip Ethereum, which currently has a market cap of $218 billion.

Does Cosmos crypto have a future?

Cosmos is an interoperability solution that hopes to solve a major pain point in Web3. The project’s future, nonetheless, depends on the level of adoption it receives.

Can Cosmos beat Ethereum?

Ethereum (ETH) is more popular than Cosmos (ATOM) and remains the hotbed for decentralized finance (DeFi) activity. Still, Cosmos has several advantages over Ethereum in terms of scalability, flexibility, and interoperability.

Is Cosmos a scam?

Cosmos was launched in 2019 and has continued to operate for the last four years. The Interchain Foundation oversees the blockchain’s development.
