@eljunich The Optimism Foundation focuses on developing a decentralized web through blockchain technology to create a more secure and equitable internet architecture.

The Optimism Foundation aims to expand the blockchain ecosystem towards a decentralized web, creating a new internet architecture that eliminates centralized entities in favor of permissionless protocols. The superchain developed by Optimism is highly scalable and operates horizontally, relying on the collaboration of multiple blockchains. Synchronizing a blockchain requires more hardware as its computational load increases, so scalability is achieved by running multiple blockchains simultaneously. However, traditional approaches have drawbacks as each chain employs its own security model, introducing systemic risks with the addition of new chains. Creating new chains is costly due to the need for establishing validator sets or producers from scratch. By integrating Layer 2 solutions to establish a multi-chain ecosystem, resources can be freely exchanged between chains as commodities. This enables developers to create cross-chain applications without concerns over systemic risks.

@adrianemilianoc Optimism Foundation develops superchain for decentralized web using permissionless protocols to reshape blockchain landscape.

@GonaGona01 Empowering individuals by decentralizing control, building a more secure and inclusive online world.

@GonaGona01 Optimism's Superchain requires multiple blockchains to participate for horizontal scalability and synchronization.

Superchain was founded with the mission of integrating the Optimism Mainnet and OP Chains to establish a seamless ecosystem for internet-level scaling. Projects within the Superchain will utilize the OP Stack for deployment (a suite of tools for streamlining processes and building Layer 2 blockchains). This integration will also provide shared communication capabilities, bridges, security measures, governance structures, and network enhancements. The Optimism Foundation aims to expand the blockchain ecosystem to the decentralized web, replacing centralized entities with a permissionless protocol. The Superchain is designed to be horizontally scalable, requiring collaboration from multiple blockchains. To achieve horizontal scaling, blockchains must operate in parallel, as the hardware requirements increase proportionally to the workload. However, conventional designs face limitations as each new chain introduces a new security model, heightening systemic risk within the ecosystem.

The Superchain concept introduces revolutionary scalability to the Optimism network and blockchains within the OP Chain ecosystem. This innovation is akin to the Cosmos ecosystem and Avalanche's subnet. By merging the Optimism Mainnet network with OP Chains utilizing the OP Stack, the Superchain aims to establish a cohesive ecosystem for achieving internet-scale growth. Projects within the Superchain will operate on the OP Stack, which simplifies the deployment process for Layer 2 blockchains. Furthermore, they will leverage shared resources such as communication capabilities, bridges, security structures, governance, and network upgrades. The Optimism Foundation envisions expanding the blockchain ecosystem to the decentralized web - a reimagined internet network that replaces centralized entities with permissionless protocols.

Ethereum has shifted its focus from execution sharding to data sharding due to limitations and risks. This change aims to solve the expansion problem for Rollups through the use of "blobs". Data blobs are processed, stored, and verified by consensus nodes independently of the execution layer. EVM cannot access or store data in blobs, benefiting Rollup the most. Storage is sold in integer units of blobs, each equivalent to 128 kB, with pricing determined by market supply and demand.

Blob is a specialized tool created to offer temporary storage for Ethereum applications, with a special focus on Rollup technology. Initially, Ethereum had planned to implement execution sharding, where each shard could run different programs. However, due to various limitations and risks, developers shifted their focus to data sharding and introduced "blobs" to address scalability issues in Rollups. Data blobs are processed, stored, and verified by consensus nodes independently of execution nodes, ensuring that EVM remains unaffected and does not store data in blobs. This upgrade greatly benefits Rollup technology, allowing for more efficient data storage and processing.

@KellyLarochelle limitations of the network, allowing for parallel processing and increased scalability while maintaining the security and integrity of the blockchain.

@1996Montjo Ethereum transitioned from program sharding to data sharding to improve scalability by dividing the database into smaller, manageable pieces for parallel processing.

Ethereum initially aimed to execute sharding to run different programs on separate shards but decided to switch to data sharding due to limitations. "Blobs" will now solve expansion issues for Rollups, processed by consensus nodes. Rollup enhances most from this. Data is stored in blobs not accessible by EVM, sold in integer units equivalent to 128 kB. Price will depend on supply and demand.

@NicolasIF123 Execution shards are designed to support specific programs while adhering to limitations. Each shard has a unique purpose and functions independently.

Every execution shard is purposefully crafted to support the running of distinct programs. However, in light of certain constraints and risks, Ethereum developers opted to shift towards data sharding as a solution to expanding Rollups through the utilization of "blobs". Data blobs are unique in that they are managed, stored, and confirmed by consensus nodes on the consensus layer, separate from the execution nodes on the execution layer. This implies that the EVM is unable to access or retain data within blobs, making Rollup the primary beneficiary of this enhancement. Data storage capacity is offered in whole units of blobs, with each blob equating to 128 kB. The cost for utilizing blob resources will be determined based on the market's supply and demand dynamics. The baseline level comprises 3 blobs per block, which is equivalent to 384 kB. As the number of blobs utilized exceeds 3, the succeeding blob price will escalate by 12.5%; conversely, if the number of blobs used remains at or below 3, the blob price decreases by 12.5%.

@NicolasIF123 Shards within an execution shard can run different programs in separate environments, maximizing efficiency and allowing for parallel processing of tasks.

Each shard within the execution shard is capable of running different programs in its designated environment. However, to overcome limitations and risks, Ethereum developers opted for data sharding to address the scalability issue of expanding Rollups using "blobs". Data blobs are uniquely processed, stored, and verified by consensus nodes at the consensus layer, separate from execution nodes at the execution layer. This setup ensures that the Ethereum Virtual Machine (EVM) cannot access or store data within blobs, making Rollup the primary beneficiary of this enhancement. Data storage is quantified in integer units of blobs, where each blob equals 128 kB. The pricing for utilizing blob resources will vary based on market supply and demand dynamics. The base level includes 3 blobs per block, totaling 384 kB. If the number of blobs exceeds 3, the subsequent blob price rises by 12.5%; conversely, when the number of blobs used is 3 or fewer, the blob price decreases by 12.5%.

Following the successful deployment of the upgraded version of Dencun, Layer 2 wasted no time in rolling out the update. Projects such as zkSync, Starknet, Arbitrum, Base, and Optimism have all launched updated versions, resulting in a noticeable reduction in transaction fees for most of these projects when sending ETH. This cost decrease can be attributed to the significant drop in data storage expenses. Each execution shard can be tailored to support the execution of diverse programs. To address limitations and risks, Ethereum developers have opted to implement data sharding and tackle the scalability issue of expanding Rollups through the use of "blobs". Data blobs have the distinctive trait of being handled, stored, and validated by consensus nodes on the consensus layer separately from execution nodes on the execution layer. This means that the Ethereum Virtual Machine (EVM) cannot access or store data in blobs. Rollup stands to gain the most from this upgrade. Data storage space is purchasable in whole units of blobs. Standard transaction fees remain unchanged, with calldata incurring a charge of 16 gas for non-zero bytes and 4 gas for zero bytes. Only blob transactions are subject to fees determined by the gas fee market.

@liz__azs Data sharding in Ethereum means dividing data into smaller parts to run multiple programs simultaneously, enhancing scalability and efficiency of the blockchain network.
