**Our next testnet**
--------------------

We’re currently fine-tuning our new design and the rollup contract codebase. Upon completion, this will be deployed as Taiko’s Alpha-6 testnet, featuring a four-tier proof system. The percentages in the below diagram represent the probability that a block will require a given tier as its minimum proof level.

In the upcoming A6 testnet, we’ll employ a cooldown period of 24 hours for all tiers.

Finally, our primary aim is for Contestable Rollups to combine the strengths of Optimistic Rollups and ZK-Rollups. If you're keen to see how this innovative design unfolds in practice, we invite you to join our community for further updates!
