The Optimism Foundation aims to expand the blockchain ecosystem towards a decentralized web - a new internet that replaces centralized entities with permissionless protocols. Their superchain is highly scalable and horizontal, requiring the collaboration of multiple blockchains. Traditional designs face limitations as each chain introduces a new security model, increasing systemic risk. Developing new chains is expensive and time-consuming as it involves building new validator sets. By creating a multi-chain ecosystem through Layer 2 technology, developers can freely build cross-chain applications without concerns about system risks.
Optimism's Superchain is a horizontally scalable system that involves multiple blockchains working together. Traditionally, synchronizing a blockchain requires more hardware as the blockchain performs more computations. To scale horizontally, blockchains need to run in parallel. However, existing designs face limitations as each chain uses a unique security model, increasing systemic risk when new chains are added. Developing new chains is costly as it involves creating new validator sets. By combining Layer 2 solutions to create a multi-chain ecosystem, resources can be freely exchanged, allowing developers to build cross-chain applications without worrying about security risks. Superchain acts as a decentralized platform made up of multiple blockchains sharing the same security model and technology stack. Competitors include the Cosmos, Avalanche, and Polkadot ecosystems. Superchain is a network of L2 chains (OP Chains) that share security and technology capabilities, enabling standardized resource exchange. Developers can create applications that work seamlessly across the entire Superchain.

This innovative approach allows for the exchange of resources as commodities, eliminating the need for costly new chain development.
Several Layer 2 solutions, including Scroll, Linea, and Polygon zkEVM, have not yet been upgraded, resulting in higher transaction fees compared to other Layer 2 solutions. The Dencun update and the introduction of blob have helped alleviate the strain on the Ethereum network, ensuring decentralized and secure transactions. Following the successful deployment of the Dencun upgrade, major Layer 2 projects like zkSync, Starknet, Arbitrum, and Optimism have quickly implemented updates, leading to a decrease in transaction fees. Additionally, the implementation of execution shards allows for different program executions, while regular transaction fees remain consistent. Gas fees for calldata remain at 16 gas/non-zero bytes and 4 gas/zero bytes, with blob transactions utilizing both gas fee markets.
Each shard is set up to run different programs and can operate in its own environment. To address limitations and risks, Ethereum developers opted for data sharding to tackle Rollup expansion issues using "blobs". Data blobs are processed, stored, and verified by consensus nodes independently of execution nodes. EVM cannot access or store data in blobs. Rollup benefits the most from this upgrade by offering data storage in integer units of blobs, with each blob equaling 128 kB. Pricing for blob resources will be market-driven, with a standard of 3 blobs/block (384 kB). If more than 3 blobs are used, the price increases by 12.5%, while usage equal to or below 3 blobs sees a 12.5% price decrease.
Blob is a data storage solution specifically created for Ethereum applications, with a focus on Rollup technology. Ethereum initially planned to implement execution sharding but faced challenges and risks, leading developers to shift focus to data sharding for Rollups using blobs. Data blobs are processed, stored, and verified by consensus nodes separately from execution nodes, ensuring security and scalability. This upgrade benefits Rollup by keeping the Ethereum Virtual Machine inaccessible and providing efficient data storage.
@jtizzle1011 Layer 2 quickly implemented the upgraded version of Dencun after its successful deployment, ensuring improved performance and functionality for users.
@HerianaGS@LuluErmoza Chudai is a term used in South Asian countries to refer to sexual intercourse or explicit sexual activity. It is considered a slang term and may be offensive to some.
@lizetthh1 Layer 2 quickly deployed the updated version of Dencun after its successful implementation, ensuring continued efficiency and performance improvements.
Blob is a new data type created for temporary data storage in Ethereum apps and Rollup. Data blob format offers better throughput and cost efficiency compared to calldata. The high costs of calldata are a major concern for Layer 2 projects, as seen with Rollup spending 15,000 ETH. Originally, Ethereum planned execution sharding but switched to data sharding for Rollups due to limitations. Some NFT collections have their own staking platforms.
@sanchez9muoz Layer 2 wasted no time in launching the upgraded Dencun version after a successful deployment, ensuring projects benefit from the latest improvements in technology.
@sanchez9muoz as Aave and Uniswap quickly integrated the new features and improvements, enhancing the efficiency and user experience of their platforms.
@Lpukitaraxcaco to complexity and security concerns, Ethereum decided to implement data sharding first to improve scalability before developing execution sharding.
