Gnosis Chain has activated a version of Ethereum’s Dencun (Deneb–Cancun) upgrade, enabling type 3 “blob” transactions (EIP‑4844 proto‑danksharding) on its sidechain ahead of their activation on Ethereum mainnet. According to Gnosis and core developer communications, the hard fork went live without reported issues and the chain is now finalizing blocks that include blob-carrying transactions. These blobs are a new transaction data format designed to carry large, temporary chunks of data more efficiently than standard calldata, primarily to support rollups and other scaling solutions. Dencun combines an execution-layer upgrade (Cancun) and a consensus-layer upgrade (Deneb), with EIP‑4844 as the most prominent change. On both Ethereum and Gnosis Chain, blob transactions expand data availability and introduce a separate fee market for blob data, which is expected to significantly reduce costs for rollups and other data-intensive dapps using these networks as a data layer. By going live with blobs early, Gnosis Chain positions itself as a testing and proving ground for proto‑danksharding behavior in production, giving infrastructure providers, rollups, and application developers an environment to integrate and optimize blob usage before and alongside Ethereum mainnet’s own Dencun activation. This move underscores Gnosis Chain’s role as an Ethereum-aligned sidechain focused on scalability and provides an earlier path to cheaper data for applications that choose to settle or post data there.
