Cosmos Hub (ATOM) Cryptocurrency
Core Definition and Technology
Cosmos is a decentralized network of independent blockchains powered by the Tendermint Byzantine Fault Tolerant algorithm, a coordination system that can achieve consensus even in an environment that potentially contains malicious nodes. The Cosmos mainnet is also called Cosmos Hub. Cosmos Hub was the first blockchain to be launched on the Cosmos Network, and its task is to link other blockchains (called zones in the network).
The Cosmos Hub acts as the central router, coordinating the network, while the ATOM token secures it through staking, powers governance, and facilitates transaction fees. The project's ultimate vision extends beyond creating an ecosystem within its own network—it aspires to become the foundational protocol for an "internet of blockchains." Just as the internet serves as the foundation for countless web-based applications, the CosmosNetwork envisions itself as the base layer connecting self-sovereign blockchains throughout Web3.
Blockchain Architecture
The Cosmos network is composed of three layers: the application layer, the consensus layer, and the networking layer. Cosmos incorporates Tendermint BFT in the consensus and networking layers and utilizes Cosmos SDK as a tool in the application layer.
The Hub in the Cosmos network plays a crucial role in ensuring interoperability among various Zones. It acts as a central point for connecting different blockchains, allowing them to communicate and transfer assets seamlessly. Each Zone within the Cosmos ecosystem operates independently, with its own set of rules and consensus mechanisms, providing flexibility and customization for developers and users alike.
Cosmos utilizes the IBC protocol to enable communication between Zones and the Hub, facilitating the seamless transfer of assets and data across different chains.
Consensus Mechanism and Network Security
The Cosmos network uses the Tendermint consensus engine, which uses a Proof-of-Stake (PoS) algorithm to secure the network. The PoS algorithm allows for fast transaction processing and a high degree of security while also reducing energy consumption compared to Proof-of-Work (PoW) algorithms.
Tendermint's security derives from its use of optimal Byzantine fault-tolerance via super-majority (>⅔) voting and a locking mechanism. The Ignite consensus protocol has been battle-tested since it was founded in 2014. As of H1 2022, Ignite has not suffered any security breaches since its inception.
Cosmos relies on a 100-validator node network to maintain consensus, security, and operational efficiency. For this system to properly function, it is imperative that users stake their ATOM coins.
Primary Use Cases and Applications
Cosmos' technology has enabled the growth of applications in DeFi, gaming, and decentralized cloud computing, making blockchain use cases more accessible and practical. Various applications can be built on the Cosmos ecosystem, including DeFi protocols, gaming applications, and supply chain management platforms.
The pioneering Interchain Security feature enables the Cosmos Hub to provide security services to other blockchains in the network. This not only improves security across the board but also creates additional value and utility for the ATOM token.
By November 2022, more than 40 blockchains were connected to the Inter-Blockchain Communication (IBC) protocol and 250+ apps were active on the network.
Founding Team and Project History
The idea of a Proof-of-Stake blockchain with Byzantine Fault-Tolerant (BFT) consensus mechanism originates from the year 2014 when the future Tendermint Inc. co-founder Jae Kwon explored the possibilities in his research. With the participation of Ethan Buchman, the other Tendermint Inc. co-founder, this idea was further developed in 2015, and Cosmos was introduced in 2016.
By February 2017, following the model set by Ethereum, a non-profit was established in Switzerland called the Interchain Foundation (ICF). The ICF was governed by a Foundation Council (FC) consisting initially of Jae, Ethan and a local Swiss board member named Guido Schmitz-Krummacher.
The Interchain Foundation held the first series of fundraising with a two-week initial coin offering (ICO) of the ATOM token in 2017, accumulating over $17 million. Cosmos mainnet eventually launched in April 2019, when its genesis block was mined, and investors received their ATOM.
The Cosmos Stack and platform is maintained by the Cosmos Labs team. The Interchain Foundation funds the development of the Cosmos stack as an open-source public good. Cosmos Labs leads development and growth for Cosmos, the Cosmos stack, and Cosmos Hub blockchain, and provides blockchain advisory.
Tokenomics
Supply and Distribution
ATOM has a very specific total supply — 260,906,513 to be exact. Of these, at the time of writing, about 203,121,910 were in circulation. The full unlock schedule extends infinitely as the token has infinite supply.
The Cosmos Hub allocation includes Interchain Foundation at 3.07%, Strategic and Early Adopters at 2.16%, Seed Contributors at 1.56%, Block Rewards at 69.34%, Public Fund Raisers at 20.81% and All in Bits Inc (Tendermint Inc.) at 3.08%.
Inflation and Deflationary Mechanics
Cosmos uses an inflationary supply model where the ATOM supply increases over time to incentivize staking. However, inflation is dynamically adjusted based on the percentage of tokens staked. Cosmos operates on a Proof of Stake (PoS) model where new ATOM tokens are created as staking rewards. This process is inherently inflationary as it increases the total supply of ATOM over time. The inflation rate is designed to encourage participation in the network's security through staking.
The Cosmos community has approved proposals to cap the Atom inflation rate, with one such proposal reducing the maximum inflation from about 14% to a maximum of 10%.
A portion of the transaction fees collected on the Cosmos network can be burned. This is a common practice in many blockchain ecosystems to control the circulating supply of the native token.
Token Functions
ATOM is the native cryptocurrency of the Cosmos network and plays a crucial role in its governance and security measures. Atom tokens are used for staking, voting on network upgrades, and participating in the consensus process through delegation.
ATOM serves as the native cryptocurrency of the Cosmos blockchain, playing vital roles in security, governance, and network operations. All users of the CosmosNetwork must pay small amounts of ATOM to cover transaction fees when transferring coins or making purchases.
Staking and Rewards
Staking involves delegating ATOM to a trusted validator, who uses these tokens to help secure the network and confirm transactions. In return, delegators earn a share of block rewards and transaction fees, creating a source of passive income.
There are two main groups that can engage in ATOM staking – delegators and validators. Validators actively participate in network consensus by operating validator nodes, while delegators stake their ATOM to validators they trust. By delegating to a validator, the user is allowing the validator to use their delegated stake to participate in consensus.
Developer Tools and Framework
Cosmos offers a suite of developer-friendly tools, including the Cosmos SDK and IBC protocols, which streamline blockchain creation and cross-chain connections. By simplifying consensus, governance, and smart contract features, these tools reduce complexity and accelerate time to market. Developers can customize their blockchains—known as "zones"—to fit diverse needs.
The Application BlockChain Interface (ABCI) creates the opportunity for developers to write blockchain applications in any programming language, as it essentially acts as a translator between the Tendermint Core and all applications built with the Cosmos SDK.
Inter-Blockchain Communication (IBC) Protocol
The IBC protocol was introduced in March 2019 as a key component of the Cosmos vision to enable communication between different blockchain ecosystems. Cosmos IBC has had multiple phases of development, refining its performance and security features over time. IBC became a foundational piece for connecting the Cosmos ecosystem, which consists of numerous sovereign blockchains known as "zones" that operate with their own validator sets and governance structures.
The IBC does not involve third parties to achieve cross-chain communication. By delving into its architecture and functionality, it is possible to understand that if a user trusts the consensus mechanism that two blockchains have, they can also trust the IBC communication between them.
Since its launch four years ago, IBC has become one of the most popular cross-chain messaging systems in web3, facilitating an average of up to $3B in transaction volume between over 115 blockchains every month.
IBC Eureka Upgrade
Eureka offers seamless bridging and interoperability to hundreds of chains, with one IBC connection to the Cosmos Hub. Access 120+ chains from Cosmos to Ethereum and beyond, with faster-than-finality transfers, low fees, and native asset issuance.
Chains that connect to IBC Eureka get light client-based interoperability, offering maximum security, with minimum infrastructure overhead – using the Cosmos Hub and the Skip API to route IBC transactions to hundreds of IBC connections.
Key Partnerships and Ecosystem Integrations
The Binance Chain, which is the token-emitting platform of the decentralized Binance Launchpad project, is built on the Cosmos ecosystem. With successful implementations including BSC, Cronos, and Osmosis, the CosmosNetwork has proven its capability to support large-scale blockchain projects.
Interchain Labs tested an IBC transaction from Cosmos Hub to Ethereum, showing progress in native interoperability between the two chains. Cosmos developers have been working to extend the Inter-Blockchain Communication (IBC) protocol, a cornerstone of the Cosmos ecosystem, to Ethereum. The development is part of the Eureka upgrade for the Cosmos ecosystem, which is expected to be released this year.
Competitive Advantages and Unique Value Proposition
Cosmos stands out by focusing on interoperability through its Inter-Blockchain Communication (IBC) protocol and Tendermint consensus. Rather than existing as a single chain, Cosmos is a hub of interconnected "zones," each free to adopt its own rules and functionalities. This design fosters seamless collaboration, allowing decentralized apps to operate across multiple chains. As a result, developers gain flexibility, and users benefit from an expanding, interlinked blockchain ecosystem.
Cosmos is the most performant, customizable, and EVM-compatible Layer 1 blockchain stack, in production for 7+ years across 200+ blockchains.
