Key terms

Cosmos

Ecosystem of interoperable sovereign blockchains. Founded by Jae Kwon (Tendermint 2014); whitepaper 2016; Cosmos Hub mainnet March 2019; IBC March 2021.

Tendermint / CometBFT

BFT consensus algorithm. CometBFT is the successor to Tendermint Core (forked 2023). 1-6 second blocks, instant economic finality, ~10K TPS theoretical.

Cosmos SDK

Go framework for building application-specific blockchains. Modular architecture; 200+ production chains run on it.

IBC (Inter-Blockchain Communication)

Standard protocol for transferring tokens, data, and messages between Cosmos chains. 115+ interconnected chains; ~$3.5B 30-day volume.

Cosmos Hub (ATOM)

The original Cosmos chain. Provides Interchain Security (leasing security to other chains). 12-15% APR staking; 61.4% staking ratio.

Osmosis (OSMO)

Dominant DEX hub for Cosmos. Concentrated liquidity, superfluid staking. Most IBC volume routes through Osmosis.

Celestia (TIA)

First modular data availability network. Mainnet October 31, 2023. Data availability sampling for light clients. 580K wallet airdrop.

Berachain (BERA)

EVM-compatible Cosmos chain. Mainnet February 6, 2025. Pioneered Proof of Liquidity consensus. $3.1B Boyco TVL.

dYdX v4

Perpetual futures protocol that migrated from Ethereum L2 to dedicated Cosmos chain (Nov 2023). Decentralized in-memory orderbook on validators. Revenue to DYDX stakers.

Stride (STRD)

Liquid staking provider for Cosmos chains. Issues stATOM, stOSMO, stTIA. Uses Interchain Accounts (ICA / ICS-27).

IBC Eureka

Extension of IBC beyond Cosmos. Launched April 10, 2025 by Interchain Labs. Enables <$1 Ethereum-Cosmos transfers in seconds.

App-chain thesis

The argument that some apps benefit from their own chain rather than running as smart contracts. Provides performance, sovereignty, and value capture; costs include bootstrap and composability fragmentation.
