QuarkChain (QKC), the innovative sharding-based public blockchain, has announced pivotal updates in 2025, including its strategic shift toward Ethereum Layer2 solutions. Below are the latest developments and historical milestones shaping QKC's ecosystem.
Key Updates (2025)
1. QuarkChain's Transition to Ethereum Layer2
QuarkChain revealed plans to evolve into an Ethereum Layer2 network post-Cancun upgrade, leveraging zk Fraud Proof technology and Parallel EVM to enhance scalability, reduce congestion, and lower transaction fees. This move aims to align with Ethereum's ecosystem while maintaining QKC's high throughput.
2. European Central Bank Approves DLT Settlement Project
The ECB greenlit "Pontes" and "Appia" initiatives to integrate distributed ledger technology (DLT) for settling transactions with central bank money. Pilot testing begins in Q3 2026, signaling institutional adoption of blockchain infrastructure.
