We’re super excited to announce that Katla (Alpha-6) testnet is now live and accessible to everyone!
Katla is the most significant testnet we’ve had so far. Let’s see what Katla brings to the table and how you can get involved.
Here’s what’s new with Katla:
Implemented Based Contestable Rollup (BCR) design with multi-proofs and SGX.
Updated bridge implementation, refined bridge UI, and a new feature: NFT bridging!
Updated testnet stats in block explorer and status page.
Let’s take a look at each of the points in more detail.
Katla implements the Based Contestable Rollup (BCR), a rollup design that we introduced back in September 2023 at TOKEN2049 in Singapore. With Katla, we enable a multi-proof configuration with four tiers: Optimistic proofs, SGX proofs, SGX+zkEVM proofs, and guardian proofs as shown below.
To learn more about BCR and Taiko’s multi-proof design, please read this blog post.
On top of that, Katla’s code supports EIP-4844 (proto-danksharding) but this feature is turned off. When the base layer (Holesky) hard forks with EIP-4844, we’ll likely perform an upgrade to enable the use of blobs for data availability to reduce transaction costs.
All in all, Katla is still a based rollup and a type-1 ZK-EVM with exactly the same tokenomics design as in the Jólnir (Alpha-5) testnet. In other words, your application should work out of the box without any modifications.
We’ve also fixed a few bugs in the bridge contract. The bridge app has also been reimplemented and NFT token bridging is now enabled. If your bridged operation on the destination chain failed, you can now claim back your bridged asset on the source chain. A complete changelog can be found here. And the bridge can be accessed here.
Besides the major updates detailed above, users, as always, will be able to swap, use various dapps deployed on Taiko, deploy contracts, run a node, propose, and prove blocks — all permissionlessly. To do all of that, visit our updated documentation here.
Katla also features an updated block explorer with new testnet stats.
For example, you can now see what’s the latest liveness bond, how many transitions were proved with what proof tier, and other stats.
You can find the Katla block explorer here.
Jólnir is going to be deprecated on January 31st, 2024.
We want to emphasize that Katla is the most important testnet we’ve had so far as it lays the foundation for our upcoming mainnet launch. That’s also why we need to make sure we test new features like contestation and SGX proof generation thoroughly.
And that’s where you — the community — come in. From participating in the contestation game to running a node to swapping — whatever way you interact with Katla helps us ensure that once we’re on mainnet, there are no surprises and everything works as intended.
We want to thank you in advance for helping us test out new futures and thus playing a big part in Taiko’s future. Taiko ≡ its community. 🫶

Taiko’s fourth testnet has arrived! Eldfell L3 (alpha-4) is our first experiment with inception layers and a new staking based proving design. We are launching this testnet in order to test two things:Deploying Taiko on Taiko as an L3 inception layer (a rollup on a rollup 😏)Testing a new staking based prover economicsOur alpha-N releases are always experiments to test our hypothesis on the protocol and build a more robust system.
