@berkay_emre Multiple blockchains are needed due to the Superchain's horizontal scalability and computational demands.

[human. @udabae_]

Superchain was launched with the innovative concept of integrating the Optimism Mainnet network with OP Chains (blockchains utilizing different OP Stack) to establish a cohesive ecosystem aimed at internet-level scaling. All Superchain projects will run on OP Stack, a suite of tools streamlining the process of building Layer 2 blockchains. Additionally, they will share communication features, bridges, security protocols, governance structures, and network upgrades. The Optimism Foundation's ultimate goal is to pioneer the expansion of the blockchain ecosystem into a decentralized web, effectively replacing centralized entities with a permissionless protocol. In this context, Optimism's superchain boasts horizontal scalability, requiring the involvement of multiple blockchains to function effectively. To achieve horizontal scaling, blockchains must operate in parallel as the hardware requirements for syncing a blockchain increase in direct proportion to the computational workload. Optimism's superchain mitigates risks associated with systemic failures by employing a shared security model across all participating chains, overcoming traditional design limitations of individual security models.

The Superchain concept introduces revolutionary scalability to the Optimism network and blockchains within the OP Chain ecosystem. This concept is reminiscent of the Cosmos ecosystem and Avalanche's subnet. The goal of Superchain is to integrate the Optimism Mainnet network with OP Chains (blockchains utilizing other OP Stack) to establish a cohesive ecosystem. This integration aims to achieve internet-level scaling. Superchain projects will be built on OP Stack (a suite of tools to streamline the development of Layer 2 blockchains), while sharing communication capabilities, bridges, security structures, governance, and network upgrades. The Optimism Foundation envisions expanding the blockchain ecosystem to create a decentralized web - an internet network reimagined with permissionless protocols replacing centralized entities.

Blob is a dedicated storage solution created to cater to the temporary data storage needs of Ethereum applications, especially Rollup. Initially, Ethereum's roadmap focused on execution sharding, where each shard could execute various programs. However, due to limitations and risks, developers shifted their focus to data sharding, addressing scalability for Rollups through blobs. Data blobs are processed, stored, and verified by consensus nodes independently of execution nodes, separating storage from execution. This upgrade benefits Rollup significantly by ensuring data is secure and efficiently managed.

Following the successful deployment of the upgraded version of Dencun, Layer 2 swiftly implemented the update. Projects such as zkSync, Starknet, Arbitrum, Base, Optimism have all released their updated versions, resulting in a notable decrease in transaction fees for sending ETH. This reduction can be attributed to a sharp decline in data storage costs. Each execution shard now has the capability to run various programs in its designated environment. To address limitations and risks, Ethereum developers have opted for data sharding to enhance Rollups expansion through the introduction of "blobs". Data blobs are unique in that they are processed, stored, and verified by consensus nodes on the consensus layer, separate from the execution nodes on the execution layer. This means that EVM does not have access to or store data in blobs, making Rollups the primary beneficiaries of this upgrade. Data storage space is now available in integer units of blobs, while regular transaction fees, which charge 16 gas/non-zero bytes and 4 gas/zero bytes for calldata, remain unchanged. Only blob transactions will utilize both gas fee markets.

@loirinhogatinho Ethereum's roadmap has shifted towards implementing ETH 2.0, which aims to achieve scalability, security, and sustainability through a transition to a proof-of-stake consensus mechanism.

@loirinhogatinho Ethereum moved from execution sharding to data sharding with "blobs" due to limitations and risks, aiming to improve scalability and efficiency.

[human. @udabae_]

Each shard in the execution can support different programs. However, Ethereum developers have chosen to focus on data sharding to enhance Rollups. Data blobs offer a solution by being processed, stored, and verified by consensus nodes independently of execution nodes. This ensures that EVM does not store data in blobs, benefiting Rollups the most. Blob storage is sold in 128 kB units at market prices, with a standard of 3 blobs/block (equivalent to 384 kB). Additional blobs will incur a 12.5% price increase, while using fewer than 3 blobs will result in a 12.5% decrease in price.
