For quite some time now, we have been looking into and exploring the universe of COSMOS blockchains. Many developers we work with have been gaining experience with technologies allowing us to develop smart contracts and other applications within the COSMOS ecosystem. It's about time to introduce you extensively to the principles and background beyond this exciting and innovative blockchain solution.

So, what is this COSMOS thing?

COSMOS is a decentralized network of independent blockchains that can communicate with each other, allowing developers to create custom blockchains and connect them to the broader ecosystem.

The COSMOS network provides a way for different blockchain networks to exchange information and value with each other, making it easier for developers to build scalable and interoperable applications. This means that developers can create specialized blockchains for specific use cases, such as supply chain management or identity verification, and still have them communicate with other blockchains on the network.

In summary, COSMOS is a blockchain ecosystem that allows developers to create and connect their custom blockchains to the network, enabling interoperability and scalability across multiple blockchains.

Beginnings and Initial Coin Offering

The COSMOS project was first announced in 2016 by Jae Kwon, the founder and CEO of Tendermint, the company behind the development of the COSMOS software. Kwon had previously worked on other blockchain projects, including the Tendermint consensus engine, designed to address some of the scalability and interoperability issues early blockchain systems face.

The original vision of COSMOS was to create a network of interoperable blockchains that could communicate and exchange data seamlessly without intermediaries or centralized exchanges. The project was designed to be modular and flexible and able to support a wide range of applications and services built on top of the network.

To achieve this vision, the COSMOS team developed several key technologies, including the Tendermint consensus engine, which provides fast and secure transaction processing, and the Inter-Blockchain Communication (IBC) protocol, which allows for seamless communication and asset exchange between different blockchains.

In 2017, the COSMOS team launched an initial coin offering (ICO) to raise funds for the project's development, which raised over $17 million in just 28 minutes. Since then, the COSMOS ecosystem has snowballed, with a vibrant developer community and a wide range of projects and applications built on top of the network.

Overall, the beginnings of COSMOS were marked by a bold vision for a more interconnected and interoperable blockchain ecosystem and a commitment to developing innovative technologies to make this vision a reality.

Basic principles behind COSMOS 

Some of the most essential features of the COSMOS blockchain include:

1. Interoperability: The COSMOS network is designed to allow different blockchains to communicate with each other, enabling interoperability across the network.
2. Customizability: Developers can create custom blockchains on the COSMOS network tailored to their specific needs and use cases.
3. Scalability: The network is designed to scale horizontally, meaning that other chains can be added to the web to increase capacity and performance.
4. Proof of Stake: COSMOS uses a Proof of Stake consensus algorithm, which is more energy-efficient than Proof of Work and allows users to earn rewards by staking their tokens.
5. Governance: The network is governed by a decentralized community of validators who vote on proposals for upgrades and changes to the network.
6. Security: The COSMOS network uses a Byzantine Fault Tolerance consensus algorithm, which ensures the security and integrity of the network.

These features make COSMOS a flexible, scalable, and secure blockchain ecosystem that enables interoperability and customizability for developers building decentralized applications.

The IBC

IBC stands for Inter-Blockchain Communication, a protocol that enables different blockchains to communicate and exchange data and assets within the COSMOS ecosystem. IBC allows for interoperability between other blockchains, meaning that applications built on one blockchain can interact with applications built on another, even if they have different protocols, consensus mechanisms, or token economics.

In simple terms, IBC allows for different blockchains to become interconnected and work together seamlessly, creating a network of blockchains that can communicate and exchange value without intermediaries. This enables various use cases, such as cross-chain asset transfers, decentralized exchanges, and multi-chain smart contracts.

The IBC protocol is a crucial feature of the COSMOS ecosystem, as it allows for greater flexibility, scalability, and interoperability between different applications and services built on the network. It also provides for the creation of new business models and opportunities that were previously not possible with traditional centralized systems.

Staking mechanisms in detail

Staking in the COSMOS ecosystem allows token holders to participate in network consensus and earn rewards. The staking process involves locking up a certain amount of tokens as collateral, which is used to support the security and stability of the network.

Here's a simplified overview of how staking works in the COSMOS ecosystem:

1. Token holders lock up their tokens as collateral, which is used to participate in network consensus.
2. Validators responsible for processing transactions and maintaining the network are chosen through a decentralized governance process. Validators must stake a certain amount of tokens to be eligible for selection.
3. Validators earn rewards for processing transactions and maintaining the network, and a portion of these rewards are distributed to stakers as an incentive to participate in network consensus.
4. If a validator acts maliciously or fails to meet their obligations, they may be slashed, which means that a portion of their stake is confiscated as a penalty.
5. Token holders can delegate their stake to a validator, who will handle the technical aspects of staking. In return, the validator takes a small fee from the rewards earned through staking.

Overall, staking in the COSMOS ecosystem provides a way for token holders to participate in network consensus and earn rewards for doing so while also supporting the security and stability of the network. It also provides a way for validators to earn rewards for processing transactions and to maintain the network, which helps to incentivize participation in the ecosystem.

COSMOS ecosystem projects that stand out

There are several vital projects within the COSMOS ecosystem, each with unique features and use cases. Some of the most notable projects include:

1. Cosmos Hub: This is the central hub of the COSMOS ecosystem, which acts as a gateway for other interconnected blockchains on the network. It is responsible for securing the network and governing changes to the ecosystem.
2. IRISnet: IRISnet is a decentralized network that connects various distributed ledgers and facilitates the exchange of assets and data. It provides an infrastructure for building enterprise-level applications on top of the COSMOS ecosystem.
3. Kava: Kava is a decentralized lending platform that allows users to borrow and lend digital assets securely and transparently. It uses various collateral types to support lending and provides staking and governance features for its users.
4. Akash Network: Akash is a decentralized cloud computing platform that allows developers to deploy and scale applications on a global network of providers. It uses a Proof of Stake consensus algorithm to ensure the security and reliability of the network.
5. Band Protocol: Band Protocol is a decentralized oracle platform that provides reliable and secure data feeds for smart contracts. The Band Protocol enables the integration of off-chain data into on-chain smart contracts, making it possible to create complex decentralized applications that require real-world data.
6. Secret Network: Secret Network is a privacy-focused blockchain allowing encrypted transactions and data storage. The Secret Network uses a combination of secure enclaves and cryptographic techniques to ensure that sensitive data remains private and confidential.
