About Cosmos
Cosmos is a decentralized network of independent blockchains designed for interoperability. Its core business includes the Cosmos SDK, a modular framework for building custom blockchains, and the Inter-Blockchain Communication (IBC) protocol, which enables secure data and asset transfer across chains. The primary market pain point Cosmos addresses is blockchain isolation—the inability of different chains to communicate natively, which fragments liquidity and user experience. By providing a standardized protocol for cross-chain interaction, Cosmos solves this by allowing sovereign chains to exchange data and tokens seamlessly while maintaining their own governance and security.
Its core competitive advantage lies in its "internet of blockchains" narrative: instead of forcing all applications onto one chain, it enables a heterogeneous ecosystem where specialized chains can interoperate. This is supported by a robust SDK that reduces development time and a proven IBC standard adopted by over 100 chains.
In the past six months (2026-02-28 to 2026-08-29), Cosmos has seen significant growth in IBC activity, with monthly active addresses rising 138% year-over-year and cross-chain transaction volume reaching $7.4 billion. However, the ecosystem faced a major security incident in August 2026: a critical vulnerability in the Cosmos EVM module was publicly disclosed without coordinated private alerts, leading to exploits on chains like MANTRA, TAC, and KiiChain, causing token losses exceeding 90% for some assets. This exposed weaknesses in cross-chain security coordination and emergency response. Additionally, several ecosystem projects, including Neutron and Mars Protocol, ceased operations or migrated away, reflecting ongoing challenges in retaining builders despite technical progress.
Cosmos, known as the Internet of Blockchains, launched its mainnet in March 2019 with the Cosmos Hub. Its core innovations include the Tendermint consensus engine (later renamed CometBFT), the Cosmos SDK for modular blockchain development, and the Inter-Blockchain Communication (IBC) protocol enabling cross-chain data transfer. The ecosystem expanded rapidly with projects like Evmos, Noble, and Pryzm. However, recent years saw significant setbacks: in 2024, a critical 0-day vulnerability in CometBFT was disclosed, and the Cosmos EVM module suffered a major security incident in August 2025, leading to exploits on chains like MANTRA and TAC. Several ecosystem projects ceased operations or migrated away, including Pryzm, Evmos, and Noble. Cosmos Labs also acquired Mintscan, a block explorer. These events highlight both the technical ambition and the challenges of maintaining a fragmented multi-chain ecosystem.
Positive: Cosmos Labs is advancing ATOM tokenomics overhaul, cutting inflation from 20% to 10% in stages and planning a shift to a fee-driven model, potentially improving holder benefits; the 2026 release of Cosmos Stack Ledger 2026.1 boosts performance to 2,000+ TPS, enhancing network stability.
Negative: In August 2026, a critical Cosmos EVM vulnerability was exploited, with hackers stealing about $5.8M across six chains; Cosmos Labs initially misjudged the risk and delayed fixes for about four months, undermining market confidence and pressuring ATOM's price.

Cosmos recently experienced team changes. David Zhou, who served as Operations Partner since December 2024, departed in April 2026. Shortly after, in May 2026, Nico Poggi joined as Chief Business Officer. Poggi brings extensive experience in blockchain business development and marketing, previously holding senior roles at Cosmos-related entities. These shifts signal a strategic focus on expanding Cosmos's commercial partnerships and institutional adoption.
