Ethereum-equivalent zero-knowledge (ZK) rollup Taiko introduced preconfirmations on its Hekla testnet, aiming to improve transaction speed ahead of full deployment on the Alethia mainnet. This stage employs a temporary whitelist system and features configurable block durations with users expected to observe improved responsiveness due to targeted block times of two seconds. These timings may be further reduced depending on network throughput, data availability advancements, and ongoing efficiency gains in ZK-proof technology.
This rollout represents the initial phase of a planned two-part upgrade. The current implementation limits sequencing to approved participants, while the subsequent phase will introduce permissionless sequencing. This phased structure mirrors the network’s earlier transition to open block proposing.
In order to support resilience and infrastructure diversity, the testnet utilizes three distinct sequencing clients developed by Nethermind, Chainbound, and Gatacca. Each of these clients is actively contributing to the network under the whitelist model and has been released as open source.
Based preconfirmations are now live on our Hekla testnet!
We're one major step closer to bringing speed without compromise to the Taiko Alethia Mainnet. The future is fast, and the future is based.

According to Taiko, this development marks an early step in Taiko Alethia’s broader strategy to enhance user experience without compromising the core principles of its based rollup design. Public access to the Hekla testnet is open, and users can interact with the environment as usual without additional steps.
What Is Taiko Alethia?
Taiko functions as a Layer 2 scaling protocol for Ethereum that is fully open-source and permissionless, utilizing a Type‑1 ZK Ethereum Virtual Machine (EVM) to maintain full equivalence with the Ethereum mainnet.
The name “Taiko Alethia” refers to the rebranded version of the original Taiko mainnet, a change implemented in February 2025. Alethia represents the continued development of Taiko’s decentralized rollup infrastructure, which operates without a centralized sequencer and is built to scale Ethereum-compatible applications while preserving trustless execution. Since its initial deployment in May 2024, the Taiko network has recorded substantial transactional activity, surpassing 550 million transactions across the system.
The Hekla testnet, also identified as Alpha‑7, serves as the last primary testing environment before the full launch of Taiko Alethia. Introduced in April 2024, Hekla remains available as a live testbed where both users and developers can interact with features scheduled for eventual inclusion in the production network.
