What is Cosmos?
Cosmos (ATOM) is a Layer 1 blockchain platform that set out to fix one of crypto's hardest problems: getting separate networks to talk to each other. Rather than trying to be a single chain that hosts everything, Cosmos is a web of many independent blockchains that pass tokens and data between themselves. This is the idea behind its nickname, the internet of blockchains, and ATOM is the coin that powers the hub sitting in the middle of it all.
The project centres on the Cosmos Hub, a Layer 1 chain that keeps a shared ledger and helps route value between the other chains linked to it. Independent chains in the wider network are often called zones, and each one keeps control of its own rules, validators and upgrades while still being able to connect to the rest. On Digital Surge, ATOM settles on its own network and is categorised as a Layer 1 and Proof of Stake coin.
- Consensus: Tendermint, a Byzantine fault tolerant Proof of Stake engine, so there is no Proof of Work mining anywhere in the design.
- Connectivity: the Inter-Blockchain Communication protocol (IBC) moves tokens and data between chains using light client proofs rather than a single central bridge.
- Building blocks: the Cosmos SDK, a modular toolkit written in the Go programming language, lets teams launch their own application-specific chains.
- Structure: a hub-and-zone layout, with the Cosmos Hub coordinating the many sovereign chains around it.
Who created Cosmos and when?
The Cosmos whitepaper was written by Jae Kwon and Ethan Buchman in 2016, and the work was carried forward by the team at Tendermint Inc together with the Interchain Foundation. After close to three years of development, the Cosmos Hub mainnet went live in March 2019. The goal from the start was interoperability: a way for many chains to coexist and exchange value without funnelling everything through one network.
How does the Cosmos network work?
Cosmos reaches agreement using Tendermint consensus, a Byzantine fault tolerant Proof of Stake mechanism where validators take turns proposing and voting on blocks. Because it does not rely on Proof of Work, the network avoids energy-heavy mining and can finalise blocks quickly. Chains built with the Cosmos SDK then connect to one another over IBC, which uses cryptographic light client proofs so one chain can verify what happened on another without trusting a middleman. That combination is what lets sovereign chains stay independent while still moving tokens and messages between themselves.
What is ATOM used for?
ATOM is the native coin of the Cosmos Hub. It is used to pay transaction fees on the Hub and, at the protocol level, it can be delegated to validators through Proof of Stake to help secure the network and to take part in on-chain governance votes that decide how the Hub develops. Staking and delegation are features of the Cosmos protocol itself rather than a product offered through an exchange. On Digital Surge, ATOM is available to buy, hold and trade, settled on its own Cosmos network rather than as a wrapped token on another chain.
Things to consider before buying Cosmos
Cryptocurrency is volatile, and the AUD value of ATOM can rise or fall sharply over short periods, so what you hold may change in value quickly. Cosmos is also a technically ambitious project, and the value of ATOM is tied to the ongoing adoption of the wider interchain ecosystem rather than any single company. Only commit an amount you are comfortable holding through large price swings, keep your account and keys secure, and be alert to scams. This is general information only and not a recommendation, and it does not take your personal circumstances into account. Consider your own situation or speak to a qualified professional before buying.
Why Buy Cosmos?
Many Australians hold Cosmos because it is a Layer 1 built for interoperability, connecting independent chains through IBC, and because ATOM is the native coin at the centre of that interchain network. Digital Surge lets you buy ATOM with AUD via PayID or bank transfer, with low fees shown before you confirm and Australian-based support. This is general information only and not a recommendation; consider your own circumstances before buying any cryptocurrency.

How to Store Cosmos Securely
Once you buy Cosmos in Australia on Digital Surge, you can store it securely in your Digital Surge wallet for easy access and trading. For additional security, you can transfer your ATOM to:
Exchange custody: convenient for buying and smaller balances
On Digital Surge you can keep your ATOM in exchange custody, where the platform holds the keys for you. This is handy for buying, trading and smaller amounts, and it means you do not have to manage a recovery phrase yourself. Protect the account with a strong, unique password and two-factor authentication.
Self-custody wallets: you hold the keys
For full control you can withdraw ATOM to a self-custody wallet you own, such as a Cosmos-compatible software wallet on your phone or desktop, or a hardware wallet that keeps your keys offline. Choose one that supports the Cosmos network so your coins arrive on the right chain, and remember that some deposit addresses ask for a memo, so check the withdrawal details before you send.
Protect your recovery phrase
If you self-custody, write your recovery phrase down, keep it offline and never share it or type it into a website. Anyone who has that phrase can move your ATOM, and on-chain transfers cannot be reversed, so double-check the address before confirming. Digital Surge staff will never ask for your recovery phrase.

Frequently Asked Questions
Is Cosmos legal in Australia?
Yes. Buying, holding and selling Cosmos (ATOM) is legal in Australia, and cryptocurrency exchanges operating here must meet Australian anti-money-laundering and know-your-customer obligations, which is why you verify your identity when you sign up. Digital Surge is an Australian exchange.
What does the 'internet of blockchains' mean?
It is the phrase used to describe how Cosmos is designed. Instead of one chain doing everything, Cosmos is a network of many independent blockchains that can pass tokens and data to each other through the Inter-Blockchain Communication protocol (IBC). Each connected chain keeps its own rules and validators, but they can still work together, much like separate websites connecting over the internet.
What is the difference between the Cosmos Hub and a zone?
The Cosmos Hub is the central Layer 1 chain that ATOM secures, and it helps route value across the wider network. The other chains that connect to it are often called zones. Each zone is a sovereign blockchain with its own validators and governance, and IBC is what lets a zone communicate with the Hub and with other zones.
Do I need a Cosmos wallet to buy ATOM?
No. When you buy ATOM on Digital Surge it is held in exchange custody, so you can start without setting up your own wallet. If you would rather control your own keys, you can withdraw ATOM to a self-custody Cosmos-compatible wallet at any time.
How do I deposit AUD to buy Cosmos?
You can deposit AUD using PayID or bank transfer, both with zero deposit fees. PayID deposits typically clear quickly, so your funds are ready to use in minutes.
Do I need to verify my ID?
Yes, in compliance with Australian regulations, all users complete a quick identity verification. Most verifications are approved within minutes, so you can get started fast.
