@XGamerZeroX Optimism Foundation seeks to advance blockchain tech for a decentralized web, promoting a new internet.

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.

@sisocarol Superchain combines Optimism Mainnet and OP Chains to create a unified ecosystem for optimal network performance.

Superchain was launched with the idea of combining the Optimism Mainnet network with OP Chains to create a unified ecosystem focused on internet-level scaling. Superchain projects will be deployed on OP Stack, utilizing solutions for simplified processes and building Layer 2 blockchain technology. The goal is to enhance communication, bridge connections, improve security structures, establish governance, and upgrade network capabilities. The Optimism Foundation aims to expand the blockchain ecosystem towards a decentralized web, replacing centralized entities with a permissionless protocol. The horizontally scalable superchain requires the participation of multiple blockchains to synchronize tasks effectively. Traditional blockchain designs have limitations, as each chain introduces a new security model, potentially increasing systemic risk in the ecosystem.

@eljunich The Optimism Foundation promotes decentralization in the blockchain ecosystem to remove centralized entities.

The Optimism Foundation aims to expand the blockchain ecosystem towards a decentralized web, where centralized entities are replaced by permissionless protocols. Optimism's scalable superchain requires multiple blockchains to participate in a horizontal manner. Synchronizing a blockchain's hardware requirement increases linearly with its computation, necessitating parallel operation for horizontal scaling. However, traditional designs face limitations as each chain introduces new security risks and requires expensive development. By implementing Layer 2 solutions to create a multi-chain ecosystem, resources can be exchanged as commodities, enabling developers to freely build cross-chain applications without concerns about systemic risks.

@eljunich Low hardware requirements due to horizontal scalability and collaboration of multiple blockchains.

Optimism's Superchain is a horizontally scalable solution that relies on the collaboration of multiple blockchains. The hardware requirements for synchronizing a blockchain increase proportionally to the amount of computation it performs, necessitating parallel operation for horizontal scaling. However, traditional approaches face challenges due to each chain utilizing a distinct security model, introducing systemic risks with the addition of new chains. The creation of new chains is costly, as it entails the establishment of validator sets or entirely new block producers. By integrating Layer 2 technology to establish a multi-chain ecosystem, resources across chains can be traded as commodities, enabling developers to construct cross-chain applications without fear of systemic vulnerabilities. Superchain functions as a decentralized platform comprising multiple blockchains that adhere to the same security model and utilize a unified technology stack (OP Stack). Positioned against competitors like Cosmos, Avalanche, and Polkadot ecosystems, Superchain stands out as a network of diverse L2 chains (OP Chains) that share security measures, technology stacks, and communication capabilities. This unique approach facilitates standardization and resource interchangeability, empowering developers to create applications that span the entire Superchain ecosystem.

Superchain was created with the goal of combining the Optimism Mainnet network with OP Chains to form a cohesive ecosystem for internet-level scaling. All Superchain projects will utilize OP Stack solutions for deployment. The vision of the Optimism Foundation is to expand the blockchain ecosystem into a decentralized web, replacing centralized entities with a permissionless protocol. Superchain is designed to be horizontally scalable, requiring collaboration from multiple blockchains. This approach aims to address the limitations of traditional designs, where new chains introduce new security risks to the ecosystem.

The Superchain concept revolutionizes scalability in the Optimism network and blockchains within the OP Chain ecosystem. Inspired by Cosmos and Avalanche, Superchain aims to integrate the Optimism Mainnet with OP Chains to form a cohesive ecosystem. This integration is designed for internet-scale expansion. Projects within the Superchain will utilize OP Stack solutions for simplified deployment on Layer 2 blockchains, while benefiting from shared communication, bridges, security features, governance, and network enhancements. The Optimism Foundation envisions a decentralized web where blockchain technology replaces centralized entities with permissionless protocols, paving the way for a re-architected internet network.

Blob is a specialized tool created to offer temporary storage space for Ethereum applications, with a specific emphasis on Rollup. Initially, Ethereum had a roadmap centered on execution sharding, where each shard could run different programs. However, due to various constraints and risks, the developers shifted focus to data sharding. This decision was made to address the scalability issue for Rollups using "blobs". Data blobs are unique as they are processed, stored, and verified by consensus nodes on a separate layer, apart from the execution nodes. This setup ensures that the Ethereum Virtual Machine (EVM) remains untouched and doesn't store data in blobs. Rollup stands to gain the most from this upgrade.

Blob is a novel data type created to offer temporary data storage for Ethereum apps, particularly Rollup. This format boosts throughput at a lower cost compared to traditional calldata. Call data expenses pose a major challenge for Layer 2 projects, with Rollup alone spending 15,000 ETH. Ethereum initially aimed for execution sharding but shifted to data sharding due to limitations, opting for Rollup scalability via "blob". NFT collections now have their staking platforms.

The Blob is a cutting-edge data type intended for Ethereum apps, with a special focus on Rollup. It offers a cost-effective and efficient way to store temporary data compared to traditional methods like calldata. Call data expenses are a major concern for Layer 2 projects, with Rollup alone having spent 15,000 ETH on this. Originally, Ethereum pursued execution sharding, where each shard could run various programs. However, due to challenges, data sharding was prioritized, leading to the development of Blob to address Rollup's scaling concerns.

Execution shards are able to run various programs within specific environments. To address limitations and risks, Ethereum developers chose to implement data sharding and address scalability with the use of "blobs". Data blobs are processed, stored, and verified by consensus nodes on a separate layer from execution nodes. EVM doesn't interact with or store data in blobs, benefiting Rollup groups the most. Data storage is sold in integer units of blobs, where each blob is 128 kB. Pricing for using blob resources is based on market demand, with a standard offering of 3 blobs/block (384 kB). Additional blobs increase in price by 12.5%, while prices decrease by the same percentage when using ≤ 3 blobs.

@domingossalusti Ethereum shifted focus to data sharding with Blob, a storage space for apps and Rollup, moving away from execution sharding.

@domingossalusti Ethereum opted to focus on data sharding instead of execution sharding to overcome scalability challenges and improve network performance.

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%.
