JANUARY 2024 - Ethereum is advancing its scalability and cost-efficiency with significant upgrades and Layer 2 solutions. The Goerli testnet has recently introduced the Dencun upgrade, which is a pivotal development in Ethereum's journey towards improved scalability. This upgrade encompasses EIP-4844 and is designed to pave the way for proto-danksharding and blob transactions, which are expected to significantly reduce Layer 2 fees.

In parallel, Arbitrum, a product of Offchain Labs, is making use of Optimistic Rollups to enhance transaction processing. By handling transactions off-chain and then summarizing them on-chain, Arbitrum aims to boost throughput and security, reflecting a concerted effort to refine Ethereum's network functionality. These innovations are seen as vital to supporting the expanding realm of decentralized finance.
