@lupititaorozco Optimism's Superchain involves multiple blockchains for horizontal scalability, minimizing synchronization hardware requirements.

@lupititaorozco Is minimized thanks to Optimism's innovative approach to blockchain scaling and interoperability.

Superchain was created with the goal of combining the Optimism Mainnet network with OP Chains (blockchains utilizing other OP Stack) to establish a cohesive ecosystem. The main objective behind this merger is to achieve scalability at the internet level. All Superchain projects will be implemented on the OP Stack (which offers solutions to simplify project processes and construct Layer 2 blockchains) while also sharing communication functions, bridges, security systems, governance, and network enhancements. The Optimism Foundation envisions expanding the blockchain ecosystem into a decentralized web, replacing centralized entities with a permissionless protocol. Superchain by Optimism is effectively horizontally scalable and necessitates the involvement of multiple blockchains. As the computational workload of a blockchain increases linearly, there is a need for parallel operation to scale horizontally. However, traditional designs have their limitations, as each chain adopts a unique security model, potentially increasing systemic risks when new chains are integrated into the ecosystem.

Superchain was created to combine the Optimism Mainnet network with OP Chains, using other OP Stack blockchains, to establish a unified ecosystem aimed at achieving internet-level scalability. Projects within Superchain will utilize OP Stack for deployment, a series of solutions that streamline the process of building Layer 2 blockchains. This collaboration will also involve shared communication capabilities, bridges, security structures, governance, and network upgrades. The Optimism Foundation envisions expanding the blockchain ecosystem into a decentralized web, replacing centralized entities with a permissionless protocol. The horizontally scalable superchain requires multiple blockchains to participate, as the hardware needed to synchronize a blockchain increases linearly with the level of computation. To scale horizontally, blockchains must run in parallel, yet traditional designs have limitations, such as each chain using a new security model that escalates systemic risk when introducing new chains into the ecosystem.

Each execution shard can support the execution of various programs within a specific environment. Ethereum developers decided to address limitations by moving towards data sharding and utilizing "blobs" to expand Rollups. Data blobs are processed, stored, and verified by consensus nodes independently of execution nodes, ensuring enhanced security. EVM does not access or store data in blobs, benefiting Rollup groups the most. Data storage is priced in integer units of blobs, with each blob equaling 128 kB. The cost of using blobs will vary based on market supply and demand, with 3 blobs/block being the standard offering (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.

Blob is a specialized temporary data storage solution for Ethereum applications and Rollup. Ethereum's initial roadmap focused on execution sharding, but eventually shifted to data sharding due to limitations. Blobs are processed, stored, and verified by consensus nodes separately from execution nodes, benefiting Rollup significantly. EVM does not store data in blobs, making Rollup the primary beneficiary of this upgrade.

@EhhlPaulilloo Layer 2 protocols like zkSync, Starknet, Arbitrum, Base, and Optimism swiftly upgraded their systems to enhance scalability and efficiency in blockchain transactions.

Layer 2 swiftly updated its systems. Notable projects like zkSync, Starknet, Arbitrum, Base, and Optimism followed suit, experiencing a significant reduction in ETH transaction fees due to lower data storage costs. Although execution shards can

@NicolasIF123 Each shard in the execution shard can run different programs simultaneously in its designated environment to maximize efficiency and capacity.

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%.

@LulaPame Layer 2 solutions such as zkSync, Starknet, Arbitrum, Base, and Optimism quickly implemented upgrades following the success of the Dencun upgrade.

Following the successful deployment of the Dencun upgrade, Layer 2 swiftly followed suit, with zkSync, Starknet, Arbitrum, Base, and Optimism releasing updated versions. Many saw a notable drop in ETH transaction fees due to reduced data storage costs. Although execution shards offer diverse program environments, Ethereum's shift to data sharding addresses scalability issues, utilizing "blobs" to expand Rollups. These blobs, processed and verified by consensus nodes independently of execution nodes, benefit Rollups significantly. Blob transactions utilize both gas fee markets, while normal transaction fees remain unchanged: calldata at 16 gas/non-zero bytes and 4 gas/zero bytes.

@LulaPame Layer 2 quickly rolled out the updated Dencun version after a successful deployment, ensuring improved performance and functionality for users.

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.

@panteistornito scalability and efficiency. Data sharding allows for parallel processing of transactions, reducing congestion on the network and increasing overall performance.

Executions shards can run different programs with specific environments. Ethereum developers opted for data sharding over expanding Rollups due to limitations. Data blobs are processed, stored, and verified by consensus nodes on a separate layer from execution nodes. EVM cannot access or store data in blobs. Rollup sees the most benefits from this upgrade. Blobs are sold in integer units with each equivalent to 128 kB. Pricing is based on market supply and demand, with the standard level set at 3 blobs/block or 384 kB. Prices increase by 12.5% for each additional blob used beyond 3, and decrease by the same percentage for usage under 3 blobs.

@luciamosqueira1 technical challenges and complexity, the Ethereum team decided to focus on implementing data sharding first to improve scalability before considering execution sharding in the future.

Ethereum initially planned to implement execution sharding to enable the execution of different programs on different shards. However, due to limitations and risks, developers switched to data sharding. Rollups will now address scalability issues using "blobs", which are processed, stored, and verified by consensus nodes independently of execution nodes. EVM cannot access or store data in blobs. Rollups will benefit most from this upgrade, as data storage is sold in integer units equivalent to 128 kB per blob. Prices for blob resources will be determined by market supply and demand.

@loirinhogatinho in technology and resources, Ethereum is now prioritizing the transition to Ethereum 2.0, a fully optimized and scalable blockchain network.
