What is ATOM: The Comprehensive Guide to Understanding the Open-Source Framework for Building Cross-Platform Applications

Cosmos's Positioning and Significance

In 2016, Jae Kwon and Ethan Buchman introduced Cosmos (ATOM), aiming to solve interoperability issues between different blockchains.

As the "Internet of Blockchains", Cosmos plays a crucial role in cross-chain communication and interoperability.

As of 2025, Cosmos has become a cornerstone in the blockchain ecosystem, with numerous interconnected chains and an active developer community. This article will delve into its technical architecture, market performance, and future potential.

Origin and Development History

Birth Background

Cosmos was created by Jae Kwon and Ethan Buchman in 2016, aiming to solve the lack of interoperability between different blockchain networks.

It was born during the blockchain technology boom, with the goal of enabling different blockchains to communicate and interact seamlessly.

Cosmos's launch brought new possibilities for blockchain developers and users seeking a more interconnected blockchain ecosystem.

Important Milestones

• 2019: Mainnet launched, realizing the first inter-blockchain communication.
• 2021: Major upgrade (Stargate) introduced IBC protocol for cross-chain transfers.
• 2022: Adopted by various projects, pushing ATOM price to its all-time high of $44.45.
• 2023: Ecosystem explosion, with DeFi protocols and NFT platforms leveraging Cosmos technology.

With support from the Cosmos community and Interchain Foundation, Cosmos continues to optimize its technology, security, and real-world applications.

How Does Cosmos Work?

No Central Control

Cosmos runs on a decentralized network of computers (nodes) spread across the globe, free from control by banks or governments. These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, granting users greater autonomy and improving network resilience.

Blockchain Core

Cosmos's blockchain is a public, immutable digital ledger that records every transaction. Transactions are grouped into blocks and linked through cryptographic hashes to form a secure chain. Anyone can view the records, establishing trust without intermediaries. The Inter-Blockchain Communication (IBC) protocol further enhances performance by enabling different blockchains to communicate.

Ensuring Fairness

Cosmos adopts Tendermint BFT consensus mechanism to validate transactions and prevent fraudulent behaviors like double-spending. Validators maintain network security through staking and running nodes, and receive ATOM rewards. Its innovations include faster finality and higher energy efficiency.

Secure Transactions

Cosmos uses public-private key cryptography to protect transactions:

• Private keys (like secret passwords) are used to sign transactions
• Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security, while transactions remain pseudonymous. Additional security features include multi-signature accounts and threshold signatures.
