Dencum will be Goerli's last update before the devs stop working on it

Dencun, Ethereum's upgrade that introduces ephemeral data blobs through EIP-4844, will go live on the Goerli testnet at 6:32 UTC on January 17, 2024, and will be Goerli's last upgrade before core teams stop supporting it. The upgrade will first deploy to Goerli, then to Sepolia and Holesky if no major issues are found, with mainnet activation scheduled afterward. The changes, which combine consensus and execution layer updates, are expected to help reduce L2 transaction fees. Until the upgrade, the article notes that a bug bounty for Dencun-related vulnerabilities pays a 2x multiplier, with critical bugs worth up to $500,000 USD.
