At the moment, a blockchain tends to act as its own universe with almost no way to communicate with the world outside of its network–without third-party help anyway.
As a result, bickering, tribalism, and maximalism among the supporters of the various different Blockchains has become the norm. But can there be one blockchain to unite them all? Take a trip as we explore Cosmos, the "Internet of blockchains".
What is Cosmos Network?
Cosmos' aim is simple: to enable any blockchain to communicate, share data, and transact with any other. By allowing many different blockchains to interoperate, there is less of a need for these networks to ruthlessly compete to be the one blockchain to rule them all. Instead, many different blockchains can coexist with their own specialized use cases and advantages.
Cosmos is a complete technology stack that goes beyond simply allowing different blockchains to connect and share data with each other. They have also created a streamlined development process that allows developers to create their own custom blockchain in months or even weeks, instead of years.
The combination of a relatively easy blockchain development process with the ability of new and old blockchains to interoperate should more application-specific and less general-purpose blockchains are developed.
Who Invented Cosmos?
Cosmos is based on the consensus protocol, Tendermint, which was created by Jae Kwon in 2014. To develop the complete Cosmos interoperable ecosystem, Kwon was joined by Zarko Milosevic and Ethan Buchman; he subsequently stepped down from the project in 2020.
A brief history of Cosmos
- April 2017 - $17 million is raised in the first 29 minutes of the initial Cosmos token sale.
- December 2018 - Game of Stakes is launched, which widely tested the Cosmos network for the first time.
- March 2019 - the Cosmos official mainnet is launched.
- November 2019 - Kava labs becomes one of the first projects built using the Cosmos SDK to launch its mainnet.
- February 2020 - The Cosmos team splits and founder Jae Kwon steps down as CEO.
- September 2020 - Cosmos partners with Nym to bring anonymous credentials to the Cosmos ecosystem.
- February 2021 - Cosmos launches Stargate, which includes the first public release of the Inter-Blockchain Communication (IBC) protocol.
What’s so special about it?
Cosmos is most similar to theproject, which also seeks to create an ecosystem of interoperable blockchain networks. However, unlike Polkadot, Cosmos prioritizes the sovereignty of independent blockchains, meaning they must secure themselves, have their own governance, and run their own validators.
The Cosmos technology is based on:
- Tendermint - A consensus protocol that allows developers to create a proof-of-stake blockchain that is fast, scalable, secure.
- The Cosmos SDK - Allows developers to build applications on top of Tendermint-based blockchains.
- The Inter-Blockchain Communication protocol (IBC) - A system that allows different blockchains to connect and communicate with each other.
What is Tendermint?
Tendermint is an open-source software that can be used to achieve Byzantine fault tolerance (BFT) in decentralized networks like Cosmos. In simple terms, BFT means a decentralized network is able to continue operating securely and achieve consensus about its current state even if some actors involved in the process have failed or are malicious.
Cosmos is just one of several platforms built around the Tendermint consensus engine; others include:
- Ethermint - A scalable and interoperable hybrid blockchain built using the Cosmos SDK and Tendermint.
- Terra - A delegated-proof-of-stake (dPoS) platform designed for stablecoins as a payment solution on the blockchain.
- Regen Network - A decentralized marketplace for ecological assets, data, and climate agreements.
What else is different?
Blockchains communicate with each other in the Cosmos ecosystem through a hub and zone model. For example, if you wanted to connectand through Cosmos, both blockchains would need to connect to their own zone. The Ethereum zone and Bitcoin zone would then each connect to a hub and through this shared hub, Ether and Bitcoin could be transferred between them.
What are ATOMs?
The native tokens of the Cosmos network are called ATOMs. Holding ATOMs gives the holder the ability to stake and validate blocks, vote on governance issues, and pay for transaction fees.
The initial ATOM tokens were created when the Cosmos mainnet launched and were distributed to initial donors, token sale participants, the Cosmos Foundation, and core developers. New ATOMs are generated as rewards for network validators.
How to buy ATOM
ATOMs can be traded on major exchanges such as Binance, Kraken, and Poloniex. You can also receive ATOMs through staking directly as a validator or indirectly as a delegator.
But if you're looking to buy ATOM outright, here's how to do it on Binance.
Step 1: Create your Binance account and sign in.
Step 2: Navigate to your spot wallet and deposit the cryptocurrency you want to trade for ATOM. As of writing, Binance supports trades against Binance USD (BUSD),(USDT), Binance Coin (BNB), Bitcoin (BTC), and USD Coin (USDC).
Once selected, load your account with this cryptocurrency and wait for it to confirm (it will show in your balance once confirmed). For the purposes of this tutorial, we'll show you how to trade USDT for ATOM, but the process is largely the same regardless of which asset you choose.
Step 3: Head over to the ATOM/USDT trading page. On the bottom, you'll find the order panel.
Here, select the 'Market' option and enter the amount you want to spend on ATOM and click the 'Buy ATOM' button when you're ready to execute your order at the best available price.
Your ATOM will then be available in your Binance spot wallet.
What can you do with ATOMs?
Cosmos operates on a proof-of-stake consensus mechanism. That means that ATOM holders are able to earn a share of the network’s block rewards and transaction fees through staking, either by running their own validator node or by delegating their ATOM coins to a validator.
Validators stake or lock their ATOMs and run specialized software, which maintains the Cosmos network by proposing new blocks and validating transactions.
Holders can also choose to delegate their ATOM coins with validators instead of running the validator software themselves, which still allows them to receive a portion of the rewards for staking.
dApps built on Cosmos
As an interoperable, highly scalable blockchain network capable of hosting smart contracts, Cosmos has become popular amongdevelopers that want to build efficient cross-chain decentralized applications (dApps).
Some of the most prominent dApps currently operating on Cosmos include:
- Anchor - a financial platform that offers low-volatility interest rates on stablecoin deposits.
- Flares - a payment network that supports multiple assets and payment systems including games and .
- Klever - a mobile app with integrated blockchain wallet, browser, and portfolio.
- Chainweaver - an interoperable multi-blockchain wallet and development environment.
Each change, upgrade, or feature activation in the Cosmos protocol depends on approval by ATOM holders. Because the Cosmos network launched relatively recently and is still somewhat in its developmental stage, it hasn't yet fully realized the vision set out in its whitepaper.
Cosmos community of validators, developers, integrators, clients, end users and $ATOM holders...Stargate is live!
Congrats to Cosmos Hub Validators and engineers for making this happen! https://t.co/ZJrEa8QIq0
Today, we enter the #Stargate ! https://t.co/VOYsTKDKYe

However, with the launch of the Stargate upgrade, blockchains can now communicate with one another thanks to the Inter-Blockchain Communication (IBC) protocol—which developers are now free to build with. On top of this, the Stargate upgrade brings with it automatic upgrades, full-featured light clients, and efficiency gains of 100x, making Cosmos a force to be reckoned with.
