Unveiling the Cosmos Ecosystem: Navigating the Web of Connectivity

Within the expansive realm of blockchain technology, the Cosmos ecosystem emerges as a beacon of innovation and interconnectedness. At its core, Cosmos, with its native token ATOM, envisions the creation of a blockchain internet, adept at solving critical issues such as blockchain isolation, suboptimal performance, and rigid governance structures. This article delves into the intricate details of the Cosmos ecosystem, its foundational elements, and recent developments surrounding Cosmos 2.0.

Unveiling the Cosmos Ecosystem: Navigating the Web of Connectivity

Cosmos Foundation and Key Figures

Established in March 2019, Cosmos Hub serves as the flagship of the Cosmos network, a vision brought to life by its creators Jae Kwon and Ethan Buchman. Jae Kwon, a Cornell University computer science graduate, played a pivotal role in introducing the Byzantine Fault Tolerance (BFT) consensus mechanism through the Tendermint Core code. Despite internal conflicts in 2020 leading to Kwon’s departure from Tendermint and Cosmos, the ecosystem has continued to flourish.

Cosmos Infrastructure Layers

The infrastructure of Cosmos comprises six layers, each with distinct functionalities:

  1. Data Layer: The repository for fundamental blockchain data, including transaction information, block hashes, and key pairs.
  2. Network Layer: Comprised of nodes forming a peer-to-peer network, defining data broadcast and verification mechanisms.
  3. Consensus Layer: Implements consensus mechanisms such as PoW, PoS, or DPoS to ensure agreement on the state of the blockchain.
  4. Actuator Layer: Governs the reward and distribution mechanisms for miners, typically involving cryptocurrency incentives.
  5. Contract Layer: Encompasses scripts, code, smart contracts, and algorithms, serving as the foundation for blockchain programming.
  6. Application Layer: Hosts various blockchain applications, including decentralized applications (DApps).

To enable communication between different Layer1 blockchains, a Data Transmission Layer is introduced.

Cosmos Infrastructure Components

The core components driving Cosmos infrastructure are the Inter-Blockchain Communication Protocol (IBC), Tendermint consensus mechanism, and the Cosmos SDK:

  • IBC: Functions as the TCP/IP of the blockchain internet, allowing Layer1 blockchains to communicate with each other.
  • Tendermint Consensus Mechanism: Comprising Tendermint Core and Application Blockchain Interface (ABCI), it ensures PoS-based Byzantine Fault Tolerance, enabling secure data validation.
  • Cosmos SDK: A versatile blockchain development framework, facilitating the creation of Tendermint-based blockchains.

Cosmos Ecosystem Components:

As these foundational elements mature, the Cosmos ecosystem evolves, consisting mainly of Hubs, Zones, and Peg Zones:

  • Hub: An independent blockchain based on Tendermint consensus and supporting IBC for cross-chain transactions between multiple Zones.
  • Zone: An independent blockchain connected to a Hub, utilizing Tendermint consensus and supporting IBC for cross-chain communication.
  • Peg Zone: Facilitates communication between non-Cosmos SDK blockchains (e.g., Ethereum) and the Hub, indirectly integrating into the Cosmos ecosystem.

Cosmos Hub and $ATOM Token:

The Cosmos Hub, the first developed by the core team, uses the governance token $ATOM. However, $ATOM’s value is not directly tied to the overall prosperity of the ecosystem. While Terra Luna and Binance Smart Chain have exploded within the Cosmos ecosystem, $ATOM’s value capture capability has been criticized.

Tendermint Consensus Mechanism Operation

The Tendermint consensus mechanism operates in two main steps: selecting a proposer from validators and executing the voting process. Validators, responsible for validating recorded data, become proposers in a round-robin fashion based on their Vote Power, determined by the staked amount of tokens.

The voting process includes proposing, prevoting, precommitting, and confirming, ensuring that a proposed block is valid and agreed upon by a supermajority of validators before being recorded on the blockchain.

Governance in Cosmos Hub

Cosmos Hub governance consists of five stages: proposal, deposit, voting, tallying, and execution. Proposals can be initiated by $ATOM holders, and for a proposal to proceed, a minimum of 512 $ATOM needs to be deposited within two weeks. The subsequent two-week voting period requires staked $ATOM for participation, and the proposal passes if specific participation and agreement criteria are met.

Cosmos 2.0 Proposal

The Cosmos 2.0 proposal introduces five key elements: Inter-Blockchain Scheduler, Inter-Blockchain Allocator, Inter-Blockchain Security, Liquidity Staking, and ATOM 2.0. Notably, it aims to address issues like reducing ATOM inflation, enhancing inter-chain security, and introducing a novel concept of Maximal Extractable Value (MEV) through an inter-chain scheduler.


In conclusion, Cosmos emerges as a visionary project, aiming to create a truly interconnected blockchain internet. With over 272 active application chains, including Cosmos Hub, Juno, Terra, Evmos, and BNB Chain, Cosmos continues to foster a diverse and thriving ecosystem. While the Cosmos 2.0 proposal brings promising advancements, the community’s scrutiny ensures the ongoing refinement of this multi-chain leader’s tokenomics. As Cosmos paves the way for the future of blockchain interconnectivity, the journey promises continuous innovation and growth.
