Cero Chain: A Network Built of, by, and for Rollups

The launch of the Cero Lotus testnet marks a major milestone in Cero’s effort to revolutionize the blockchain landscape. This testnet isn’t just another step forward – it’s a leap towards a truly decentralized sequencing network that not only tackles the technical challenges faced by rollups but also reimagines their economic model.

Cero, a decentralized sequencing network for rollups, has announced the launch of the Cero Lotus testnet. This testnet marks a significant step in Cero's mission to revolutionize the blockchain landscape by creating a network that is built of, by, and for rollups.

Cero believes that rollups should have full control over their own infrastructure while also benefiting from a broader ecosystem. That's why Cero is more than just a decentralized sequencer—it's a network that is designed specifically for rollups, where they are both the primary stakeholders and the biggest beneficiaries.

Cero unites rollups across settlement layers. Whether you are a rollup that settles on Ethereum or Arbitrum One or ZkSync Era or no L1 at all (sovereign rollups), Cero aims to unify rollups across all ecosystems for better value capture and stability—a mother of all ecosystems that Cero offers as a Super-system.

Additionally, while Cero identifies as a network of rollups, it remains open to external validators to further improve participation on this security layer. Rollups' participation ensures that sequencing takes place however the Super-system seems apt.

Today's rollups face a major challenge: economic sustainability. The reliance on transaction fees in a single token makes revenue unpredictable and volatile. Cero fixes this problem by customizing the economic model for rollups to create stable and diversified income streams for rollup operators.

This means rollups participating in the Super-system gain financial stability rather than facing economic uncertainty. Plus, Cero is already working on additional mechanisms to further improve rollup sustainability.

Security is for everyone, especially for end users. Cero ensures that every transaction is protected, fairly ordered, and guaranteed to settle correctly by—

Trust-minimized infrastructure: Every transaction is cryptographically verified and fairly sequenced before being included in a block.

Open participation: Anyone can join the network as a validator or rollup, ensuring that no single entity has outsized control.

Immutable record: Once a block is finalized, it cannot be altered, providing a permanent and tamper-proof record of transactions.

By leveraging trust-minimized infrastructure, rollups using Cero gain security guarantees that centralized sequencing solutions simply can't match.

No two rollups are the same, and Cero recognizes that a one-size-fits-all approach does not work for most. That's why Cero is designed to be highly configurable and modular, allowing rollups to tailor their sequencing and settlement preferences to meet their requirements.

The core framework is designed to extend operations over multiple L1s for settlement and multiple DAs for data storage preferences. This is how Cero intends to create the Super-system of rollups across various ecosystems.

Realizing that the preferences of rollups are even more granular, Cero has a big list of other options that it's looking to work on. Stay tuned!

The Cero Lotus Testnet is now live, offering rollups the opportunity to experience the future of decentralized sequencing.

What's Inside?

The Cero Lotus Testnet is an early-release network for the purpose of early integrations with their partners and preparing for what comes next. The next launch would be the permissionless and persistent network, which would be usable for production purposes by testNets across various stacks. To get more details, feel free to reach out.
