Cosmos SDK

This article provides a brief overview of Cosmos SDK.
The Cosmos SDK is an open-source framework for building multi-asset public Delegated Proof-of-Stake (dPoS) blockchains, like the Cosmos Hub, as well as permissioned Proof-of-Authority (PoA) blockchains.
The goal of the Cosmos SDK is to allow developers to easily launch custom blockchains that can natively interoperate with other Cosmos blockchains.
Blockchains built with the Cosmos SDK are generally referred to as application-specific blockchains.
In the traditional blockchain model, decentralized Apps (dApps) are built on top of an existing blockchain as a set of programs called a smart contracts. This model can be very limiting, and often falls short for building complex decentralized platforms.
An application-specific blockchain is a blockchain customized to operate a single application: developers have all the freedom to make the design decisions required for the application to run optimally. Building applications this way provides more flexibility to the developers, and can increase performance, sovereignty and security.
Fun fact: Cosmos SDK is maintained in part by a group of developers at Regen Network Development, Inc (RND)!
