The Cosmos project is a highly forward-looking and innovative blockchain cross-chain project launched by the Tendermint team in 2016. The goal of the Cosmos project is to ultimately realize the "Internet of Blockchains" by realizing a basic function such as token transfer, and to construct a deeply integrated token economic ecosystem. Cosmos Hub is the first cross-chain Hub in the Cosmos ecosystem. ATOM is the pledge equity token of Cosmos Hub, which can be used for spam prevention mechanisms, mortgage dividends, and community management voting mechanisms.

ATOM uses the POS mechanism and is issued additionally at a rate of 7% to 20% every year. 1. If the amount of ATOM participating in Staking mining is greater than 2/3 (i.e. 66%), the corresponding additional issuance rate will be lower, with the minimum value being 7%. 2. If If the amount of ATOM participating in Staking mining is less than 2/3, the corresponding additional issuance rate is higher, with a maximum value of 20%.

Blockchain problems that Cosmos can solve

1. Scalability

Proof-of-work protocols are slow, expensive, unscalable, and environmentally harmful.

Tendermint BFT solves this problem.

Tendermint BFT is a Byzantine fault-tolerant consensus engine that powers Cosmos Proof of Stake.

2. Ease of use

Blockchain applications are complex and difficult for developers to understand.

The Cosmos SDK fixes this issue.

The Cosmos SDK is a modular framework for building interoperable, application-specific blockchains.

3. Interoperability

The blockchain economy is isolated and unable to transfer assets between each other.

The IBC protocol solves this problem.

Inter-Blockchain Communication (IBC) is a blockchain messaging protocol similar to TCP/IP.

Key features and milestones

Tendermint Core: “Tendermint Core” is a ready-to-use blockchain engine equipped with the Cosmos Practical Byzantine Fault Tolerance consensus protocol. The core can be used to build public or private blockchains. The consensus mechanism provides instant settlement and security; security is prioritized, followed by network activity.

Cosmos SDK: As a convenient toolkit, Cosmos SDK helps developers build application-specific blockchains.

Cross-chain communication: In order to provide developers with more tools to build blockchains, the next goal of the Cosmos project is to improve the interoperability between different blockchains and achieve cross-chain and cross-layer transactions. With the help of zone combinations, users can trade freely within the token ecosystem composed of IBC compatible chains.
