Cosmos SDK

P2P Platform

A modular, open-source framework for building application-specific Layer-1 blockchains ("appchains"), pairing with the CometBFT (formerly Tendermint) BFT consensus engine. Used by 200+ chains in production, including Cosmos Hub, Osmosis, and (per this matrix) did-cheqd and ixo's Impact Hub. Cosmos Labs, the primary commercial steward of ongoing SDK development, is a wholly-owned subsidiary of the Interchain Foundation (a Swiss nonprofit).

Platform Evolution & Sovereignty

P2P Platform Atributos

Origins Application-specific blockchain framework, enabling developers to build sovereign, purpose-built chains rather than deploying smart contracts on a shared chain.
Database Chain-specific — each SDK-built chain has its own state store (typically IAVL tree-backed).
Query Language gRPC/REST query endpoints, auto-generated per-module from Protobuf definitions.
Data Formats Protobuf.
Collaborative Live Editing N/A
Rich Text Editing N/A
Mobile Support N/A directly (individual chains' wallet ecosystems provide this)
Web Support N/A directly (chain-specific frontends/block explorers provide this)
Native Apps N/A (a framework, not an end-user app)
Terms Free, open-source framework; individual chains set their own transaction fee/gas models.
Funds Not centrally tracked at the SDK level (individual chains have their own treasuries).
Based On Pairs with CometBFT/Tendermint BFT consensus; IBC (this story's own separate entry) for interchain communication.
P2P Architecture Inherits CometBFT's validator-gossip P2P network for whichever chain is built with the SDK.
Development Tools Full module framework (bank, staking, gov, IBC, etc.), CLI scaffolding (ignite/formerly starport), extensive documentation and tutorials.
Deployment Options Self-hosted validator/full-node deployment (each SDK chain runs its own independent network); no managed/hosted option from Cosmos Labs itself.
Authentication & Identity Cosmos SDK accounts (secp256k1/ed25519 keypairs), with an x/auth module handling account state.
Storage Model On-chain, IAVL-tree-backed key-value store per chain.
Interoperability Native IBC support (this story's own separate entry) for cross-chain communication with any other IBC-enabled chain.
