Cosmos and EVM Role

CrossFi Chain leverages the capabilities of Cosmos and Ethereum Virtual Machine (EVM) to create a scalable, interoperable, and high-performance blockchain ecosystem. Each component plays a distinct role, ensuring efficiency, security, and flexibility for developers, businesses, and end users.

Cosmos Role

CrossFi Chain integrates Cosmos technology to achieve high performance, security, and scalability. Cosmos is responsible for the core blockchain operations, providing a robust foundation for interactions with other system components.

Key Functions of Cosmos in CrossFi Chain

• Consensus Management – Ensuring data consistency through a fast and secure consensus mechanism.

• Block Production – Generating new blocks containing transactions to be added to the blockchain.

• Block Verification – Validating and confirming the integrity of new blocks.

• Transaction Processing – Handling transactions and including them in blocks.

• Token Issuance – Managing the creation of new tokens according to the economic model.

These functions are powered by the Byzantine Fault Tolerant (BFT) consensus mechanism, Tendermint Core, and the Cosmos SDK, which streamline blockchain application development.

Tendermint Core

Tendermint Core is an open-source blockchain development software that enables application creation in any programming language. Its primary advantage is speed—transactions are included in blocks within seconds and require minimal confirmation time.

Tendermint's BFT-based architecture enhances network security by automatically blocking nodes that transmit invalid data, ensuring the integrity of the blockchain.

Cosmos SDK

The Cosmos SDK is a framework designed to help developers build customizable blockchains using the Tendermint consensus engine. It abstracts low-level blockchain complexities, allowing developers to focus on application logic instead of network architecture.

Cosmos and EVM Synergy in CrossFi Chain

The integration of Cosmos and EVM provides a powerful and flexible platform for decentralized applications. From the Cosmos perspective, this synergy manifests in:

• Extended Functionality – Cosmos serves as a robust blockchain foundation, while EVM enables Ethereum-compatible smart contracts.

• Scalability – Tendermint Core ensures fast transaction processing and dynamic network scaling under heavy load.

• Interoperability – Inter-Blockchain Communication Protocol (IBC) allows CrossFi Chain to interact with other blockchains, expanding application possibilities.

• Security – BFT-based Tendermint consensus provides network reliability, which is further reinforced by EVM security layers.

Cosmos establishes the foundation, while EVM expands its capabilities, allowing developers to benefit from both performance and functionality.

Technical Advantages of Cosmos in CrossFi Chain

• Consensus Protocol: Delegated Proof of Stake (DPoS)

• Byzantine Fault Tolerance: Up to one-third of malicious nodes tolerated

• Maximum Validators: 64

• Block Time: 5 seconds (scalable to 1 second)

• Transactions Per Second (TPS): Up to 10,000

• Operations Per Transaction: Up to 100

• Transaction Finality: 1 block

• Base Transaction Fee: $0.02

EVM Role

CrossFi Chain integrates Ethermint and Evmos to enable full Ethereum Virtual Machine (EVM) compatibility. This allows developers to build and deploy Ethereum-based smart contracts and decentralized applications (dApps) with native support in the CrossFi ecosystem.

Key Functions of EVM in CrossFi Chain

• Smart Contract Execution – Supporting Ethereum-compatible smart contracts.

• Decentralized Application (dApp) Deployment – Enabling seamless integration of Ethereum-based applications.

• Full EVM Compatibility – Ensuring developers can use existing Ethereum tools and frameworks without modification.

This is achieved through Cosmos SDK, Ethermint, and Evmos, which provide an EVM-compatible, Proof-of-Stake (PoS) blockchain.

Ethermint

Ethermint is a Cosmos SDK module that enables the deployment of scalable, EVM-compatible blockchains. It combines the flexibility of Cosmos with the smart contract capabilities of EVM, ensuring high performance and seamless interoperability.

Evmos

Evmos is the first EVM-compatible blockchain in the Cosmos network. It implements an EVM stack designed for native cross-chain applications, serving as the flagship Ethermint implementation.

Why CrossFi Chain Uses Ethermint and Evmos

Ethermint and Evmos enable full Ethereum Virtual Machine (EVM) compatibility, allowing CrossFi Chain to support:

• Smart contract execution compatible with Ethereum.

• DeFi services for yield farming, staking, and liquidity pools.

• Anonymous payments with enhanced privacy features.

• Account abstraction, including biometric authentication and two-factor security.

• Cross-chain bridges to transfer digital assets between blockchains.

• Payment channels for instant transactions.

• Native MetaMask and wallet integration.

• Creation and issuance of custom crypto assets across EVM-compatible networks.

Advantages of Delegated Proof of Stake (DPoS) in EVM

CrossFi Chain leverages Delegated Proof of Stake (DPoS) with Ethermint and Evmos to:

• Reduce block finalization time to 1 second.

• Process up to 100 operations per transaction.

• Achieve a throughput of up to 10,000 transactions per second.

• Minimize transaction fees to as low as $0.02.

Benefits for Developers and Users

• EVM Compatibility – Developers can use familiar tools and programming languages, such as Solidity, for smart contract development and dApp deployment on CrossFi Chain.

• High Performance – DPoS and Ethermint enable fast block confirmations, low-latency transactions, and minimal fees.

• Interoperability – IBC integration with Cosmos allows CrossFi Chain to seamlessly interact with other blockchains, facilitating cross-chain data and asset transfers.

• Enhanced User Experience – Account abstraction and native wallet integrations (MetaMask and others) simplify blockchain interactions, making CrossFi Chain more accessible to mainstream users.
