Excited to share that the Cronos EVM mainnet v1.8 upgrade is targeted for October 22, 2026.
This is a huge milestone for the base layer, integrating with the latest Cosmos SDK while delivering native parallel execution, lower propagation latency, and much deeper Ethereum compatibility.
Here’s what’s under the hood:
- Parallel EVM (Block-STM): Native multi-threaded execution embedded directly into the Cosmos SDK layer for higher sustained throughput.
- Faster Networking: Swapped the P2P stack to libp2p and introduced an app-side mempool to cut block turnaround overhead.
- 90%+ EVM Equivalence: Added 80+ Ethereum API methods so native tooling and dApps work seamlessly out of the box.
- Plus 40+ upstream stability fixes.
Simulation & Benchmark Highlights:
- Faster Block Times: Shaved block propagation latency by ~20%, sustaining median block times under 400ms across high-load sweeps.
- Throughput Headroom: Multi-node cluster simulations showed significant double-digit throughput gains alongside lower gas saturation before approaching network limits.
Peak Execution Ceiling: In ideal single-node batching tests, the engine delivered a ~15% boost in peak execution throughput at the hardware limit with zero execution stalls.
Validators and node operators, please check out the migration guide to prep your nodes ahead of the 22nd.
