According to a recent LinkedIn post from Espresso Systems, the Espresso Network has transitioned to a proof-of-stake consensus model and moved from a permissioned validator set to a permissionless one. The post indicates that as of block 11,040,000, an open set of nodes now secures the network, which the company characterizes as a major milestone.

The LinkedIn post notes that Espresso Mainnet 0.0 launched in November 2024 with 100 nodes run by 22 validators and has since finalized more than 70 million blocks for chains such as ApeChain, RariChain, AppChain, and Molten. It highlights that this infrastructure aims to deliver transaction finality in seconds, in contrast to the longer finality times it attributes to Ethereum.
As described in the post, Mainnet 1.0 opens network participation to anyone willing to stake the $ESP token, shifting Espresso’s security model toward broader economic security. For investors, the move toward permissionless proof-of-stake could strengthen the network’s decentralization and appeal to institutions seeking faster settlement infrastructure, potentially enhancing Espresso Systems’ competitive position in blockchain scalability and enterprise-focused infrastructure.
