# The Rollup Coaster #18 By [Taiko Labs](https://paragraph.com/@taiko-labs) · 2024-01-25 --- **The Rollup Coaster** is a bi-weekly newsletter that dives into the fascinating world of Ethereum, exploring the latest in rollups, zero-knowledge proofs, MEV-PBS, and much more. This edition is written by Taiko’s Community Advocate [Jünger](https://twitter.com/Junger0x). Hold on tight! 🎢 _Disclaimer: This newsletter is neither financial advice, nor is indicative of Taiko’s position on any of the material presented. Please do your own research._ * * * Highlights 🎢 ------------- * Taiko’s Katla Testnet (Alpha-6) is now live! In this testnet, Taiko integrated the Based Contestable Rollup (BCR) design, multi-proofs, and SGX. Check the details in this [article](https://taiko.mirror.xyz/a5SHfg_V16TOVS_LpFgrbfgi_shwC5HhpPZ5C2hnuFo). * [Dencun upgrade](https://blog.ethereum.org/2024/01/10/goerli-dencun-announcement) is coming! The upgrade includes several changes, most notably protodanksharding, which will help reduce L2 transaction fees. * Vitalik in his [article](https://vitalik.eth.limo/general/2023/12/28/cypherpunk.html), advocated for a return to Ethereum's core principles of openness and decentralization. He criticized the current trend toward centralization and financialization, which had been fueled by high transaction fees and a gambling culture. Vitalik highlighted the potential of rollups, privacy enhancements, and zero-knowledge proofs to reinvigorate Ethereum's original vision. He saw a future where Ethereum could contribute significantly to a technologically integrated society, prioritizing security and decentralization. * Discussions about increasing the gas limits of Ethereum. Dankrad [pointed out](https://twitter.com/dankrad/status/1745406611202437356) that it’s important to increase the CALLDATA fee while increasing the GASLIMIT.
