Cronos Labs Unveils Public zkEVM Chain Testnet, What Makes It Unique?

• Cronos Labs introduces the Cronos zkEVM Chain testnet on the Ethereum Sepolia testnet.
• Cronos Labs says the new chain is the first public testnet utilizing the ZK Stack framework.

Cronos Labs, the pioneering force behind the Cronos ecosystem, has unveiled its latest leap into the realm of web3 innovation with the launch of the Cronos zkEVM testnet blockchain network. This layer-2 network, introduced on the Ethereum Sepolia testnet, marks the dawn of a new era in second-tier projects that strategically nestle within the Ethereum ecosystem.

The new “Cronos zkEVM Chain,” launching initially as a test platform, leverages Matter Labs’ software tools. These tools empower the creation of layer 2 and layer 3 “hyperchains” on the Ethereum foundation and show a commitment to scalability and efficiency.

Cronos zkEVM Chain Uses zkSync Tech

The testnet, powered by zkSync’s ZK Stack software kit, a brainchild of Matter Labs, introduces a new chain to the existing Cronos ecosystem, featuring the Cronos EVM blockchain and Cronos PoS chain. Further, Crypto.com, a prominent crypto exchange partner with Cronos Lab, actively contributes to the PoS chain’s source code.

The Cronos zkEVM testnet stands out as a hyperchain utilizing the ZK Scalable Transparent Argument of Knowledge (STARK) modular framework. Positioned atop the Sepolia faucet, it draws security from the Ethereum testnet concerning final settlement and data availability.

Cronos Labs states that the new chain is the first public testnet using the ZK Stack framework, running alongside Ethereum’s mainnet. The zkEVM testnet, a hyperchain, will integrate a native bridge to Ethereum by 2024.

Further, the Boojum STARK-based zero-knowledge proof system elevates the zkEVM testnet, known for low fees and GPU compatibility (16GB RAM minimum). Ongoing cost optimizations aim to maintain a competitive edge within layer 2 rollups.

The network utilizes TCRO, a testnet version of the CRO cryptocurrency from the Cronos ecosystem, as its native token for transaction fees. Additionally, it has the flexibility to support fee payments in any cryptocurrency. Moreover, internal benchmarks demonstrate the zkEVM testnet’s ability to exceed 100 transactions per second through hyperchain technology.
