Attention blockchain enthusiasts! Decentralized sequencer protocol Espresso has launched its fourth testnet, Gibraltar, and it's now open to Arbitrum developers. This testnet will allow Arbitrum developers to test their dapps using the shared sequencer network while also seeing external node operators running the network for the first time.

As we know, Layer 2 sequencers play a crucial role in processing and ordering transactions in the mempool and placing them into blocks. However, the current challenge is that many rollups run their own sequencers and execution environments, and ZK-proof solutions run their own provers, leading to trust assumptions and centralization issues.

Espresso introduces a shared sequencer network, a distributed consensus system shared across rollups. So far, it has integrated with Optimism, Cartesi, and Polygon zkEVM on testnets. How do you think this shared sequencer network will impact the blockchain landscape? Feel free to share your thoughts in the comments!
