The Cosmos ecosystem continues to evolve as one of the most innovative and interconnected blockchain networks in 2024. Known as the “Internet of Blockchains,” Cosmos enables seamless communication and value transfer between independent, application-specific chains through its robust technical foundation. At the heart of this expansive network lies the Cosmos Hub, a pivotal blockchain that serves as both a connectivity backbone and an emerging security layer for the broader ecosystem.
This article explores the core components of Cosmos, the role of the Cosmos Hub, key ecosystem projects like Neutron, Osmosis, and Stride, the resurgence of stablecoins, and how emerging integrations with platforms like EigenLayer are shaping the future of interchain interoperability.
Core Components of the Cosmos Ecosystem
To understand the power of Cosmos, it's essential to break down its foundational technologies:
CometBFT
CometBFT (formerly Tendermint) is a high-performance, Byzantine fault-tolerant consensus engine that ensures secure and consistent replication of application states across distributed nodes. It enables developers to build secure, scalable blockchains without reinventing consensus mechanisms.
Cosmos SDK
The Cosmos Software Development Kit (SDK) is a modular framework that allows developers to easily build custom, application-specific blockchains. With built-in modules for staking, governance, and token management, the SDK accelerates development while maintaining flexibility and security.
Inter-Blockchain Communication (IBC)
The IBC protocol is the cornerstone of Cosmos’ interoperability vision. It enables trustless, permissionless data and asset transfers between independent blockchains that use CometBFT or compatible consensus engines. This creates a decentralized internet of blockchains—each sovereign yet interconnected.

The Cosmos Hub: The Nexus of Interchain Connectivity
Launched in 2019, the Cosmos Hub was the first blockchain in the ecosystem and remains its central coordination point. As a Proof-of-Stake (PoS) chain with an account-based model, it does not support native smart contracts but instead focuses on three critical roles:
- Interchain Router – Establishes IBC connections between zones (independent blockchains).
- Security Provider – Shares its validator set and economic security via Interchain Security.
- Liquidity Gateway – Hosts cross-chain transactions with low fees and fast finality.
With over 67 IBC peers and 471 active channels as of late April 2024, the Cosmos Hub functions as a central hub routing traffic across the IBC network. Its native token, ATOM, powers staking, governance, and transaction fees.
Staking ATOM not only secures the network but also allows users to earn rewards from inflation and from consumer chains secured via Interchain Security—such as Neutron. Daily active user numbers have shown steady growth over the past six months, signaling increasing engagement despite no major protocol-level upgrades.
The Inter-Blockchain Communication (IBC) Protocol in Action
IBC is what makes Cosmos truly unique. Unlike wrapped assets or custodial bridges, IBC enables direct, trustless communication between blockchains. Each IBC connection consists of two components:
- Peers: Unique blockchains connected via IBC.
- Channels: Specific pathways for transferring data or tokens between peers.
With more than 400 live IBC connections, Cosmos has created one of the most organic multi-chain environments in crypto. Chains can send tokens, execute cross-chain queries, and even trigger remote contract executions—all without intermediaries.
This level of interoperability fosters true composability across sovereign chains, allowing developers to build applications that span multiple ecosystems seamlessly.
The ATOM Economic Zone (AEZ): Key Ecosystem Projects
The ATOM Economic Zone (AEZ) refers to a growing cluster of chains deeply integrated with ATOM and the Cosmos Hub’s security and liquidity. Three standout projects define this zone: Neutron, Osmosis, and Stride.
Neutron: The Interchain Smart Contract Platform
Neutron is the first consumer chain secured by the Cosmos Hub through Interchain Security, making it the most secure smart contract platform in the Cosmos ecosystem. Built using replicated security, Neutron leverages the Cosmos Hub’s validator set to inherit its decentralization and resilience.
Developers on Neutron can:
- Deploy CosmWasm smart contracts.
- Manage remote accounts on other chains.
- Access cross-chain liquidity without relying on trusted multisig custodians.
As Cosmos Hub’s default DeFi platform, Neutron enables scalable, interchain-native applications that interact with multiple zones simultaneously.
Osmosis: The Leading DEX in Cosmos
Osmosis dominates decentralized exchange activity within the IBC ecosystem. As the most connected DEX, it often serves as the first on-ramp for new chains entering the interchain network.
With a Total Value Locked (TVL) of $177 million as of April 2024—and a consistent upward trend since late 2023—Osmosis attracts liquidity providers through generous incentives and flexible AMM pools. Its deep integration with IBC allows users to trade assets across dozens of chains natively.

Stride: Liquid Staking for IBC Assets
Stride revolutionizes staking in Cosmos by offering liquid staking derivatives. Users stake ATOM or other IBC-native tokens and receive staked derivatives like stATOM in return—tokens that represent staked value and earn yield while remaining liquid.
With $150 million in TVL—80% of which is in ATOM—Stride has become a cornerstone of capital efficiency in the AEZ. Its growth reflects broader market demand for liquid staking solutions that unlock yield without sacrificing usability.
Stablecoins Return to Cosmos
After the collapse of TerraUSD in 2022, stablecoin adoption in Cosmos slowed significantly. However, 2023–2024 marked a strong comeback:
- USDT launched on Cosmos via Kava.
- USDC became natively available through Noble, a purpose-built app chain for issuing regulated assets.
- FRAX and sFRAX are now being deployed on Noble through a partnership with Frax Finance.
These developments provide much-needed stability for DeFi protocols. Noble plays a crucial role by enabling secure, non-custodial transfers of native assets across IBC chains—eliminating reliance on third-party bridges.
Additionally, decentralized options like USK (from Kujira) offer censorship-resistant alternatives, further diversifying the stablecoin landscape.
Cosmos Hub and EigenLayer: Bridging Ethereum’s Security
Cosmos is exploring new frontiers in shared security through experimental integrations with EigenLayer, despite no official cross-chain bridge yet existing.
EigenLayer’s restaking model allows Ethereum validators to secure external systems using their staked ETH. Projects like Ethos, an Autonomous Validation Service (AVS), aim to bring restaked ETH into Cosmos as a new source of economic security.
This could allow Cosmos chains to:
- Bootstrap trust layers at lower cost.
- Reduce dependency on volatile native tokens.
- Attract Ethereum-aligned developers and users.
While still early, this synergy highlights Cosmos’ ambition to become not just an interchain network—but a universal security layer.
Frequently Asked Questions (FAQ)
Q: What is the purpose of the Cosmos Hub?
