GM Saturday! Your Cartesi Weekly Report is here, bringing more ecosystem updates 🐧

PRT Honeypot is now live on the Ethereum mainnet: Cartesi's first Rollup application with functional anti-fraud security has officially launched. PRT Honeypot will conduct comprehensive testing of the application chain framework and the PRT anti-fraud system. This marks an important step towards achieving trustless security and decentralization that meets the L2BEAT @l2beat standards. The first deposit is expected to arrive next week. Explore the code, dive into the challenges, or follow the growth of the prize pool:

This milestone places Cartesi among the 26 projects maintaining Ethereum Layer-2 status in the main category of L2BEAT, while over a hundred projects have been reclassified as 'others' until they catch up:

In this way, a new era of mature rollups has begun, calling on everyone to strengthen efforts in decentralization and security, as co-founder Felipe Argento @felipeargento stated:

New features of the PRT Honeypot: anyone can become a validator. Now any node can challenge the correctness of computation and execution. This will create a fully trustless environment where users play a key role. To help you get started, the DevAdvocacy team has prepared a step-by-step tutorial:

Node version: Cartesi Rollups v2.0.0-alpha.6. The new version of the Rollups node has been released. It includes an updated Go version (1.24.4), improved deployment reporting, more concise CLI behavior, clearer error messages, and several usability improvements. This version is for testing only and not for the stable release:

It's time to release the Cartesi Weekly Report to update your ecosystem dynamics🐧

The new Honeypot system, supported by Cartesi's PRT anti-fraud system, is ready to be submitted to @l2beat and undergo the upcoming reclassification. If you haven't fully grasped it yet, let's dive straight into the second phase of Rollup.

By definition, the second phase of Rollup is the final stage of maturity, fully managed by smart contracts, and employs a permissionless anti-fraud system that allows anyone to verify and challenge state transitions.

Or, as our contributor Bruno Maia @bmaia_expat interprets the significance of this achievement: "The experimental garden becomes safer and more expressive."

We, persistently, build.

Last week, we interpreted the upcoming L2Beat @l2beat reclassification and its impact on Ethereum Rollups. Now, let's delve into the solution proposed by Cartesi for this higher standard: the PRT (Permissionless Referee Tournament) anti-fraud mechanism, which places the Cartesi Rollups SDK in its second phase.

PRT is Cartesi's first solution to this challenge (followed by the Dave proposal): a permissionless decentralized method to validate state transitions, thus resisting Sybil attacks without requiring extensive resources or trust assumptions. It aims to provide a secure, decentralized, and ultimately fast way to resolve disputes. Unlike older models that are susceptible to Sybil attacks or rely on permissioned validators, PRT aims for permissionless scalability while minimizing the burden on honest validators.

How does it work? PRT uses computational hashes. Participants no longer merely commit to the final state, but rather to the entire computational path. Thus, PRT not only exposes liars but also reveals lies.

Disputes are resolved using a bracket-style tournament. Validators can work as a team, and due to halving the claims each round, honest validators only need to complete logarithmic work in logarithmic time. Even ordinary hardware is sufficient to handle large-scale Sybil attacks.

PRT has launched an upgraded honeypot, but without an economic model. Delay attacks still exist, so it is currently not recommended for high TVL applications. However, it propels Cartesi toward its second phase Rollup deployment and aligns us with the new standards of L2BEAT.

Go out and play on the lawn, have a great weekend!🌱

We are finally seeing a consensus in the discussions and narratives surrounding the rise of these applications.

Here is the natural development path of successful applications:

**Phase 1** - Launch on shared infrastructure, pay “rent” to the ecosystem, and test the PMF thesis of the application while refining GMT.
**Phase 2** - Successful applications will transition to their own public chains to maximize value accumulation (MEV has now become a reality, no longer a secret). Owning a public chain means greater control over revenue, but also potential compliance issues.

Interoperability solutions like @EspressoSys, @LayerZero_Core, and @wormhole will inject liquidity into a robust ecosystem; funds will flow freely, providing opportunities regardless of location.

From personal experience: whoever controls customer access controls the power. Look at how Apple, Google, and Samsung have done this to infrastructure telecom operators?

Infrastructure application chains (especially emphasizing alternative virtual machines and their advanced expressiveness) provide value for an extremely secure foundational layer and will drive the deployment of valuable applications. The foundational layer will play a key role in providing security for upper-layer applications while continuing to serve as a testing ground for developers to trial their solutions and a resting place for outdated applications.

The 🍕 festival is over, and the pancake has also broken through the key point of 110K, just waiting for a breeze to come.

It's time to check out the Cartesi weekly report, where we will release some additional ecosystem updates to keep you in the loop.🐧

On the technical side: Espresso Reader v0.3.0 has been released, which is now more smoothly compatible with @EspressoSys's latest Decaf testnet and has updated support for Cartesi Node v2 alpha.4.

This means we are one step closer to developers running applications locally with Cartesi + Espresso, gaining more reliable data processing capabilities, and an SDK fully synchronized with the latest API version. Next, we will release integration with Cartesi CLI. GitHub link: https://t.co/81e8MXbFy8

Ongoing game testing: @World_Tycoon_ is now open for public testing. This city-building game similar to "SimCity" is now live. Join their Discord to start playing: https://t.co/qHuGeTstoy and contact Zac Prater @ZacPrater for more alpha versions, testnet tokens, and airdrop news. Don't forget to share your experience, just like Bubbalex @bubbalexone.
