Cronos (CRO)
Cronos is a versatile blockchain ecosystem designed to support decentralized finance (DeFi), gaming, and Web3 applications. It is recognized for its high speed, energy efficiency, and low transaction fees, making it an attractive platform for developers and users in the blockchain space. Cronos aims to cater to the creator economy and serve as a foundational layer for an open metaverse. The ecosystem features multiple chains, including Cronos EVM, Cronos zkEVM, and Cronos POS, each with distinct functionalities and capabilities. The native token, $CRO, is central to transactions and staking within the Cronos ecosystem.

Overview of the Cronos ecosystem
Cronos EVM
Cronos EVM is a blockchain built on Ethermint with the Cosmos SDK, providing a robust platform for decentralized applications and smart contracts. It is designed to be Ethereum-compatible, leveraging the Inter-Blockchain Communication (IBC) protocol to facilitate interoperability with Ethereum, Cosmos, and other blockchains. This enables users to transfer assets from these chains into Cronos, enhancing the flexibility and usability of the ecosystem.
The Cronos EVM chain employs a Proof of Authority (POA) consensus mechanism, which balances decentralization with scalability and eco-friendly processing. This mechanism allows for high transaction throughput, fast finality, and low fees, offering a cost-effective alternative to Ethereum’s mainnet. Additionally, Cronos Labs, a Web3 accelerator and ecosystem development fund, supports developers in advancing DeFi, GameFi, and the overall growth of Cronos.
Cronos POS
Formerly known as the "Crypto.org Chain," Cronos POS Chain is a Cosmos SDK-based blockchain primarily used for $CRO staking. It powers several applications within the Crypto.com ecosystem, including Crypto.com Pay. The Cronos POS Chain is designed for fast transactions and serves as a public blockchain, facilitating global transactions for individuals and businesses.
Transaction fees on the Cronos POS Chain are paid in $CRO. The chain aims to advance cryptocurrency usage in everyday settings, addressing challenges faced by traditional payment systems and existing blockchains. It seeks to provide a secure, scalable, and decentralized solution for crypto payments.
Cronos zkEVM
Launched by Cronos Labs in 2024, the Cronos zkEVM Chain is a zero-knowledge (ZK) Layer-2 blockchain developed in collaboration with engineering teams from Matter Labs (zkSync team), Crypto.com, VVS Finance, Fulcrom Finance, and Veno Finance. Built using the ZK Stack, the Cronos zkEVM is a significant step toward scalability and broader adoption within the Cronos ecosystem.
Key features of the Cronos zkEVM include integration with the Cronos user and developer ecosystem and the use of zkCRO (a liquid-staked version of $CRO) as the gas token. The network utilizes a zero-knowledge proof system for cost-efficient scalability on Ethereum security, contributing to the advancement of Ethereum scalability alongside other prominent ZK chains. It also supports a "triple yield" concept in DeFi, combining yield-bearing cryptocurrencies, DeFi returns, and loyalty points, along with native account abstraction for gasless transactions.
