The Dencun upgrade (Cancun-Deneb) has successfully been deployed on the Ethereum Goerli test network, overcoming a minor hiccup. A glitch that caused a four-hour delay was swiftly rectified with a patch.

Web3 gaming platform is launching a Layer 2 blockchain testnet, Immutable zkEVM, to reduce dependence on a single network infrastructure. The platform utilizes Polygon Supernets, which facilitate the creation of application-specific blockchains.

Ethereum-compatible Layer 1 blockchain Monad is reportedly beginning its testnet rollout, following the recent launch of its devnet—a developer testing phase.

Ethereum has just launched the Holesky test network, albeit on the second attempt. During a live broadcast on the EthStaker YouTube channel, one of the developers announced, 'It seems the launch has gone smoothly.' Meanwhile, another developer smiled and noted, 'It looks like we won't have to do this a third time.'"

The Ethereum development team is poised to initiate a test network for the forthcoming Dencun upgrade on January 17, 2024. Anticipated to bring a host of innovations, this upgrade is set to lower transaction fees for second-layer Rollups and enhance scalability.
