Overview

Blocknative's Observability Platform 

Blocknative builds infrastructure to help improve how L2s settle to the L1 and increase observability into ephemeral data layers. 

Blocknative's Gas Platform relies on Ethernow, Blocknative's flagship observablity platform. Its creation was made possible by a grant from the Ethereum Foundation. It is the comprehensive source for all live and historical Ethereum mempool data.

Blocknative envisions this level of Observability as essential for every L1 and L2, especially as we usher in the next wave of onchain users.
