@vagasatrsd Optimism Foundation seeks to shift the blockchain ecosystem towards a decentralized web by implementing permissionless protocols.

The Optimism Foundation aims to expand the blockchain ecosystem towards a decentralized web, replacing centralized entities with permissionless protocols. Optimism's superchain is highly scalable and horizontal, relying on the participation of numerous blockchains. To synchronize a blockchain, hardware requirements increase proportionally with the computation performed, necessitating parallel operation for scalability. However, traditional designs have shortcomings as each chain employs a unique security model, increasing systemic risk with new chain introductions. Developing new chains is costly due to the need for constructing new validator sets or producers. By integrating Layer 2 technology to create a multi-chain ecosystem, resources can be traded as commodities between chains. This facilitates the development of cross-chain applications without concerns about systemic risk.

The Optimism Foundation aims to expand the blockchain ecosystem into a decentralized web, replacing centralized entities with permissionless protocols. The superchain is scalable, horizontal, and requires collaboration among multiple blockchains. To synchronize a blockchain, the hardware requirement increases with the amount of computation it performs. Traditional designs have limitations, as each chain utilizes a new security model, posing systemic risk with the introduction of new chains. Developing new chains is costly due to building validator sets. By combining Layer 2 for a multi-chain ecosystem, resources can be exchanged as commodities, enabling developers to create cross-chain applications without concerns about risks.

@XGamerZeroX The foundation seeks to improve the blockchain ecosystem by developing decentralized web protocols.

The Optimism Foundation aims to enhance the blockchain ecosystem by creating a decentralized web through permissionless protocols. Their superchain is highly scalable and horizontal, requiring collaboration across multiple blockchains. By utilizing Layer 2 technology to build a multi-chain ecosystem, developers can freely create cross-chain applications without concerns about systemic risks. This innovative approach allows for the exchange of resources as commodities, eliminating the need for costly new chain development.

@XGamerZeroX to handle the increased workload, but Optimism's Superchain solves this by using multiple blockchains.

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.

Superchain was introduced with the goal of integrating the Optimism Mainnet network with OP Chains, which are blockchains based on other OP Stack protocols. This integration aims to create a cohesive ecosystem focused on achieving internet-level scalability. All projects within the Superchain network will be built on OP Stack, a suite of tools designed to streamline the development process of Layer 2 blockchains. By sharing communication capabilities, security measures, governance structures, and network enhancements, Superchain aims to establish a robust foundation for blockchain projects to thrive. The Optimism Foundation envisions expanding the blockchain landscape to include a decentralized web, effectively transforming the internet by replacing centralized entities with a permissionless protocol. Superchain's architecture is designed for horizontal scalability, requiring the collaboration of multiple blockchains to function effectively. To achieve horizontal scaling, blockchains must be able to run in parallel, as the hardware requirements for syncing a blockchain linearly increase with the level of computation performed. However, traditional blockchain designs often encounter limitations, such as the need for new security models with each chain, resulting in heightened systemic risks when introducing new chains to the ecosystem.

The Superchain initiative revolutionizes scalability in the Optimism network by merging with blockchains in the OP Chain ecosystem. Similar to Cosmos and Avalanche's subnet, Superchain combines Optimism Mainnet with OP Chains to create a seamless ecosystem for internet-level scaling. Projects on Superchain will utilize OP Stack for deployment and benefit from shared resources like communication abilities, security structures, and governance. Optimism Foundation aims to expand the blockchain ecosystem into a decentralized web, replacing central entities with permissionless protocols.

Blob is a dedicated space for temporary data storage for Ethereum apps and Rollup. Ethereum initially focused on execution sharding but shifted to data sharding due to limitations. Data blobs are processed, stored, and verified by consensus nodes independently, benefiting Rollup the most.

Blob is a specialized data storage solution for Ethereum applications, especially Rollup. Initially, Ethereum had plans for execution sharding, where different programs could be executed in separate shards. However, due to limitations and risks, developers shifted focus to data sharding and introduced "blobs" to address scalability issues for Rollups. Data blobs are processed, stored, and verified by consensus nodes independently from execution nodes, ensuring that EVM cannot access or store data in blobs. Rollup stands to gain the most from this upgrade.

@liz__azs sharding. This allows multiple transactions to be processed simultaneously, increasing the network's capacity and throughput.

@TheMatrixRecaga Execution shards are crafted for running programs, but Ethereum devs chose data sharding to improve scalability by splitting data processing across multiple shards.

Execution shards are crafted for running various programs, but Ethereum devs opted for data sharding to tackle expansion issues. Data blobs, stored and verified by consensus nodes, offer a solution for Rollups. EVM does not access or store data in blobs, benefiting Rollup the most. Blobs are sold in integer units, 128 kB each. Pricing adjusts based on market demand, starting at 3 blobs/block (384 kB). Price increases by 12.5% when blobs used exceed 3, and decreases by 12.5% when usage is 3 or less.

@1996Montjo Data sharding was chosen over execution sharding for Ethereum due to limitations. This approach involves dividing data into smaller, more manageable pieces for scalability.

Ethereum had an extensive plan for execution sharding, but due to limitations, data sharding was chosen. This new approach involves using data blobs that are processed, stored, and verified by consensus nodes independently of execution nodes. The EVM cannot access or store data in these blobs, benefiting Rollup the most. Data storage is sold in blob units, each equivalent to 128 kB, with pricing based on market supply and demand. This shift addresses expansion issues and ensures efficient execution of various programs on Ethereum.

@1996Montjo Ethereum transitioned from program sharding to data sharding to improve scalability by distributing data processing tasks across multiple shards for increased efficiency.

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.

Following the successful deployment of the upgraded Dencun version, Layer 2 wasted no time in rolling out the update. Prominent projects such as zkSync, Starknet, Arbitrum, Base, and Optimism have all released updated versions. These projects have seen a notable decrease in transaction fees when sending ETH, largely attributed to a significant drop in data storage costs. Each execution shard can now be customized to run different programs. In light of various limitations and risks, Ethereum developers have opted to implement data sharding to address scalability issues with Rollups through the use of "blobs." Data blobs are processed, stored, and verified by consensus nodes on the consensus layer, independent of execution nodes on the execution layer. This means that EVM cannot access or store data in blobs, making Rollup the primary beneficiary of this upgrade. Data storage space is now sold in integer units of blobs, while regular transaction fees remain unchanged, with calldata costing 16 gas per non-zero byte and 4 gas per zero byte. The use of gas fee markets is reserved solely for transactions involving blobs.

@DedeMedell Ethereum switched from execution sharding to data sharding due to limitations and risks, improving scalability and performance while distributing data across multiple shards.
