Cosmos allows multiple blockchains to work with each other, maintaining each other’s integrity.
Cosmos utilizes multiple tools that allow people to build and customize secure and scalable blockchain applications through Tendermint, Cosmos SDK, and IBC.
Integration and increased efficiency of the ATOM
Cosmos supports smart contracts.
The Cosmos project is a product of Tendermint’s ingenuity of putting out an open-source project that is capable of operating in multiple languages and is able to provide a synthesizing platform across blockchains.
Its end goal is the Internet of Blockchains where a network of blockchains, however varied, are able to communicate with each other and work in a decentralized environment.
The Cosmos is essentially powered by the Tendermint BFT engine that handles consensus integrity and networking, Cosmos SDK for its security in the building of blockchain applications, and IBC as the networking engine among blockchains.
Tendermint’s role in Cosmos is the networking and consensus catalyst making sure that the blockchain becomes a generic engine, allowing developers to focus on application development instead of the underlying protocol.
Tendermint also designates the Byzantine-fault tolerant consensus algorithm used within the engine. As it handles network consensus, it allows developers to build both public (PoS) and private (PoW) blockchains.
With a consensus algorithm in place, transactions passing through Tendermint are instantaneous and final.
Cosmos SDK, on the other hand, secures the blockchain. Its modular property creates ecosystems where developers are easily allowed to spin up application-specific blockchains without having to code from scratch.
Interconnectivity and synergy are key ideas of Cosmos, thus IBC or the Inter-blockchain Communication Protocol.
As its name suggests, the IBC takes care of completing transactions among heterogeneous blockchains. It allows paired heterogeneous blockchains to transfer tokens among each other.
Cosmos (ATOM) founders Jae Kwon and Ethan Buchanan, the brains behind Tendermint, present a novel blockchain network architecture that addresses the identified limitations of existing decentralized applications such as gross energy inefficiency, poor or limited performance, and immature governance systems.
Cosmos founders and programmers’ ambitious goal is an interoperable system that is capable of allowing multiple parallel blockchains while retaining individual properties. Cosmos describes its framework as a network of many independent blockchains called zones.
These zones are powered by the Tendermint Core providing a high-performance, consistent, and secure consensus engine that acts in a Byzantine-Fault Tolerance manner. Cosmos’ end goal is to create an Internet of Blockchains, independent, yet interoperable and decentralized.
Cosmos, in itself, is not a finished product but an ecosystem with constant progression being built on modular, adaptable and interchangeable tools.
The modularity of the Cosmos allows privilege zones that work with other cryptocurrencies, allowing a bridge zone for interconnection.
Cosmos strikes a balance on validators which started at 100 at its genesis, and will continue to increase by 13% annually and will settle to 300 in a span of 10 years. The rationale is to maximize validators without compromising communication speed.
