Modular blockchain Cartesi has been busy working on a new build of its Honeypot application, making it ready for use in enhancing rollup security – and the latest version packs a bunch of new features. Honeypot v2 boasts Permissionless Refereed Tournaments (PRT), an intriguingly-named fraud-proof system. It’s designed to ensure rollup resistance to Sybil attacks without forcing networks to rely on permissioned validators or heavy hardware. And it’s not the only innovation that can be found under the hood of the Honeypot dapp. Cartesi Sweetens Honeypot When Cartesi first launched Honeypot on Ethereum two years ago, the dapp effectively gamified security testing, transforming a laborious process into something more rewarding. It achieved this by implementing a community-incentivized audit and hacker battlefield. Despite these flourishes, there’s serious business being taken care of in the background. In the time that’s elapsed since Honeypot’s release, rollups have come to play an increasingly important role in onchain activity and the economic value that passes through them has soared. By processing transactions away from the main Ethereum chain, rollups allow network users to take advantage of greater throughput and lower costs. But security on these Layer-2 solutions is paramount, particularly when they’re obliged to “roll up” multiple transactions into a single batch and submit them to Ethereum. As for where Honeypot comes into all this, the app is designed to challenge the security of Cartesi rollups. Can anyone hack the application to obtain the funds locked in the rollup contract? So long as those funds remain untouched, Honeypot – and by extension Cartesi – is working as expected. The Canary in the Coalmine Honeypot is essentially the canary in the coalmine: an early warning system designed to alert blockchain users should a Cartesi rollup run into a problem. Since any project can spin up its own Cartesi rollup, the benefits of Honeypot extend far beyond Cartesi itself. As Cartesi Founder Erick de Moura explains, “Honeypots allow projects to commit their own funds to validate the integrity of their fault proofs before asking others to rely on them. It’s a gradual, transparent path toward trustless security that reflects the values this ecosystem was built on.” If Ethereum is to scale further – which by Vitalik Buterin’s admission it desperately needs to – it will fall to rollups to do a lot of the heavy lifting. Honeypot thus has a major role to play in giving projects confidence that their rollups are working as intended by allowing them to test their inviolability.
