Key Features
The modular zero-knowledge proof library, Tachyon, significantly enhances both the speed of proof generation and cost efficiency, allowing Kroma to evolve into a zkRollup network. By leveraging its modular zk proof library, Tachyon accelerates transaction processing and reduces gas fees, making the generation of zk proofs faster and more economical.
Kroma aims to create a comprehensive ZK Rollup utilizing the Optimism Bedrock framework. Presently, Kroma functions as an Optimistic Rollup integrated with ZK fault proofs, employing a zkEVM built on the Scroll platform. The long-term objective for Kroma is to transition to a ZK Rollup once zk proof generation becomes more efficient and less costly.
Kroma incorporates the OP Stack with enhancements to accommodate zkEVM, establishing a proactive fault-proof mechanism. This setup allows Kroma to manage substantial transaction volumes at minimal fees while ensuring strong security. The network utilizes optimistic rollups to promote scalability and efficiency, enabling smooth deployment of EVM-compatible gaming applications.
Key Advantages
- User-Friendliness and Accessibility
Kroma, designed as a Layer 2 solution for the gamified Web3 ecosystem, significantly enhances user-friendliness and accessibility. With over 40 games and more than 100 dApps already integrated, Kroma offers a robust infrastructure for decentralized gaming and other Web3 services.
- Seamless Gaming Experience
Kroma is a pioneer in implementing account abstraction (AA) within the Superchain ecosystem, ensuring a smooth Web3 gaming experience.
- Security
The project team conducts regular internal security audits to safeguard assets on Kroma. Additionally, external audits by third-party organizations are carried out to further enhance the security of the Kroma network.
Kroma Network operates as a Layer 2 solution leveraging the OP Stack, tailored specifically for the gaming sector. Integrated within the Superchain, Kroma aspires to establish itself as Asia’s premier blockchain ecosystem focused on gaming, delivering a scalable, secure, and efficient environment for both game developers and players.
The name Kroma is derived from the Greek word “Chroma,” reflecting the project’s mission to create a Layer 2 solution that is vibrant, scalable, and capable of organic operations. On September 7, 2023, Lightscale, a subsidiary of Wemade, launched the Kroma network, an Ethereum Layer 2 that establishes a link between the vast ecosystems of Ethereum and WEMIX. Initially starting as a gaming chain, Kroma plans to expand its offerings to include DeFi, NFTs, and more.
As part of the WEMIX mega-ecosystem strategy, Kroma will serve as a conduit for bringing Ethereum users, holders, and assets into the WEMIX ecosystem.
As the number of services on Layer 1 increases, transaction speeds decline, scalability reaches its limits, and gas fees rise. The widely used Ethereum Layer 1 faces this challenge, known as the blockchain trilemma. Layer 2 solutions address scalability issues.
Kroma offers transaction fees that are ten times lower than those on the Ethereum Mainnet while maintaining Native Ethereum Security. The project aims to develop a universal ZK solution based on the Optimism architecture.
Kroma Genesis marks the first NFT ever released by Kroma, celebrating the launch of the Kroma Mainnet.
In mid-2024, Kroma began minting its own token, KRO. Its tokenomics feature a zero-start distribution mechanism with no pre-mining. A new block is generated every two seconds, and KRO is minted and distributed to users and decentralized applications as rewards. The level of participation is determined by the number of transactions, meaning that decentralized applications and users who generate more transactions will receive more tokens. This rewards system will encourage active engagement in expanding the ecosystem, creating a positive feedback loop.
Twenty-five percent of KRO will be allocated to the fund and the community contributing to the WEMIX ecosystem. Users and dApps will be rewarded with the zero-start distribution token KRO.
In 2024, Kroma underwent significant changes in its shareholder structure, evolving from a subsidiary of Wemade to a company with a broader base of shareholders and partners, centered around its founders and leadership. This transformation will enable Kroma to grow its global business with enhanced support from a diverse range of stakeholders.
