Ethereum's Layer 2 – Post Dencun | Layer 2 Review
Ethereum's Layer 2 – Post Dencun | Layer 2 ReviewQuick Reads and Hot Links Covering the People and Projects Who Are Scaling EthereumDear Frens, Layer 2 solutions are at the vanguard of scaling Ethereum but right now it turns out not to be just a scaling solution but a revolution. Layer 2 is the buzzword resounding through the Ethereum ecosystem — from the explosive growth of Arbitrum and Optimism and projects like Base built on the OP stack to the emergence of some amazing standards like zkSync and Starknet. zkSync projects are currently demonstrating the potential for zero-knowledge proofs to revitalize not just DeFi but a wide range of applications, from gaming to supply chain management. Speaking of gaming, Polygon joined forces with Immutable to launch a 100 million USD gaming investment fund. Optimism is also moving as they are back with a more targeted form of RPGF — more on that under the Hot News section. Indeed, Layer 2 has generally transitioned from a concept of the future to a practical reality solution that enhances efficiency and accessibility in blockchain technology. Sit back as we journey into the latest updates and advancements in this fast-paced L2 space.

CeloEthereum's Layer 2 – Post DencunAuthor: Kornekt Following the implementation of EIP-4844, referred to as Proto-danksharding, we've seen drastic reductions in fees on Layer 2 networks. This reflects the positive impact of the upgrade on Ethereum's overall scalability and cost-effectiveness. Gas fees on Optimism, Arbitrum, and other major L2 networks have been reduced by over 90%, making transactions more affordable and accessible to a broader user base. These fee reductions have encouraged greater participation in decentralized applications and DeFi protocols built on Layer 2, fostering innovation and growth within the L2 ecosystem. All these are thanks to the introduction of blobs, which serve as temporary storage systems for large data packets in the consensus layer, reducing the overall storage burden and transaction costs associated with Layer 2 operations. The temporary nature of these blobs seems to raise eyebrows because it sort of contradicts the idea of immutability and permanence associated with blockchain technology. However, it is essential to understand that blobs live on Ethereum’s consensus layer and all that’s necessary is to ensure they are there long enough for all participants to verify their validity. As such, the data can be deleted after specified periods but may still be available on other off-chain storage solutions. Since rollups are the major beneficiaries of the Dencun upgrade, now would be a good time to go back to certain basics to understand how rollups inherit mainnet security. How Rollups Derive Security From Ethereum Layer 1Rollups scale Ethereum by leveraging the security guarantees provided by Ethereum Layer 1 while significantly improving transaction throughput and efficiency. At the heart of the rollups lies the fundamental principle of anchoring transaction data and state updates to the Ethereum main chain, ensuring the integrity and security of Layer 2 operations. The security model of rollups is derived from Ethereum Layer 1, which serves as the ultimate arbiter of truth and the source of trust for all transactions and smart contract executions. Rollups inherit the robust consensus mechanism of Ethereum Layer 1, relying on its decentralized network of validators to validate and confirm transactions submitted to the L2 network. Transactions processed on Layer 2 are batched and compressed as blobs, which are then submitted to Ethereum Layer 1 for verification on the blockchain. This process ensures that all Layer 2 transactions are ultimately secured by the underlying Ethereum network, providing users with the same level of security and truthfulness as mainnet transactions. Furthermore, rollups incorporate additional security mechanisms to further enhance the integrity and reliability of Layer 2 operations. One such mechanism is the use of fraud proofs or validity proofs, which allow users to challenge invalid transactions or state transitions by providing cryptographic evidence of fraudulent behavior. Moreover, rollups benefit from Ethereum's economic security model, which incentivizes validators to act honestly and follow the protocol rules. Validators are required to stake a certain amount of cryptocurrency as collateral, which they stand to lose in the event of malicious behavior or non-compliance with the protocol. Future of Ethereum Scaling – Full DankshardingDencun was only a precursor for the future of Ethereum scaling which involves full Danksharding. Full Danksharding expands Proto-danksharding by increasing the number of blobs per block from 1 to 64. This substantial increase in data blobs allows Ethereum to process a significantly higher volume of transactions. With full Danksharding, users can expect faster confirmation times and lower fees, making Ethereum even more accessible and affordable for a broader audience. While scalability and efficiency are paramount, full Danksharding prioritizes security and decentralization. The upgrade maintains Ethereum's robust security model by incorporating mechanisms for data availability sampling and proposer-builder separation. Data availability sampling ensures that transaction data remains accessible and verifiable across the network, preventing data manipulation or censorship attacks. Similarly, proposer-builder separation mitigates the risk of collusion or manipulation by separating the roles of block proposal and construction. By upholding these security measures, full Danksharding ensures that Ethereum remains resilient against potential threats while scaling to meet the demands of a growing user base and ecosystem. Wrapping It All UpThe Dencun upgrade represents a significant milestone in Ethereum's journey towards scalability and efficiency. With lower fees on Layer 2, the introduction of blobs, and the assurance of rollup security derived from Ethereum Layer 1, Ethereum is poised for a future of enhanced performance and accessibility. As we look forward to future upgrades like full Danksharding, Ethereum continues to solidify its position as a leading force in the blockchain space, driving innovation and paving the way for the decentralized future. 📈 DataTotal Value Locked on L2s is almost $40 billion!
