First blockchain Rick Roll incident? A tale about Cartesi, Espresso Rick Astley and Vienna OP

Thought you'd find this amusing – a little unexpected event in the Crypto dev world.

Espresso Systems and Cartesi recently ran into a quirky situation. Cartesi sent a 17MB video through the Espresso Sequencer, a task that should've been contained within their specific rollup. But, due to a design quirk, it ended up stalling the Vienna OP rollup.

Now for the funny part: the video was Rick Astley's "Never Gonna Give You Up." Is this the first blockchain rickroll?

While it's a lighthearted moment, it does shed light on some technical challenges. The issue was specific to the interface between the sequencer and the rollup, not the HotShot consensus or Caldera’s deployment. It's an area Espresso Systems is already planning to upgrade.

This highlights the complexities of shared sequencers like Espresso, dealing with multiple rollups in one block. They're rethinking some of these design aspects due to this incident.

Cartesi and Caldera's work on the Cortado testnet has been ambitious, and this was an unexpected but valuable test. Espresso Systems is focused on ensuring stability and improvement for their mainnet launch.

I thought it was an intriguing mix of blockchain tech and classic internet humor.
