Portal Testnet V2 is LIVE! 🚨 The next phase of the Testnet is here. Here’s everything you need to know before diving in! 🧵👇

@ElikLosika Supporting a decentralized web through blockchain technology and fostering optimism in the community.

@ElikLosika coordinating nodes across multiple chains to ensure consistent state and transaction processing.

The launch of Superchain involved merging the Optimism Mainnet network with OP Chains to establish a unified ecosystem focused on achieving internet-level scaling. All Superchain projects will be deployed on OP Stack, a collection of solutions designed to streamline processes. This involves building Layer 2 blockchains and sharing communication capabilities, bridges, security structures, governance, and network upgrades. The Optimism Foundation aims to expand the blockchain ecosystem into a decentralized web, replacing centralized entities with a permissionless protocol. Superchain is designed to be horizontally scalable, requiring the involvement of multiple blockchains. Synchronizing a blockchain's hardware requirements increase linearly with the amount of computation performed, necessitating running blockchains in parallel to scale horizontally. However, traditional designs have limitations as each chain introduces a new security model, raising systemic risks within the ecosystem.

The Superchain concept revolutionizes scalability on the Optimism network and blockchains within the OP Chain ecosystem. It is akin to the Cosmos ecosystem and Avalanche's subnet. Superchain aims to integrate the Optimism Mainnet with OP Chains using other OP Stack blockchains to establish a cohesive ecosystem for internet-level scaling. Superchain projects will operate on OP Stack, facilitating seamless deployment and sharing communication, bridges, security, governance, and network upgrades. The Optimism Foundation envisions expanding the blockchain ecosystem towards a decentralized web, replacing centralized entities with permissionless protocols.

Ethereum's roadmap originally aimed to implement execution sharding, with each shard able to run different programs. However, due to limitations, developers switched to data sharding to address scaling issues for Rollups using "blobs." These data blobs are processed, stored, and verified by consensus nodes separately from execution nodes. EVM cannot access or store data in blobs, benefiting Rollup groups the most. Data storage is sold in blob units, each equivalent to 128 kB. Pricing for blob resources will depend on market supply and demand.

Blob is a dedicated storage solution for Ethereum apps and Rollup. Ethereum's original execution sharding roadmap was switched to focus on Rollups due to limitations. Data blobs allow for secure storage, processing, and verification by consensus nodes. This upgrade benefits Rollup significantly.

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 their own updated versions as well. These projects have seen a significant reduction in transaction fees (specifically for sending ETH) thanks to lower data storage costs. Each execution shard can now be tailored to accommodate various programs. In light of limitations and risks, Ethereum developers have opted to focus on data sharding and resolving scalability issues through the use of "blobs". Data blobs are unique in that they are handled, stored, and confirmed by consensus nodes on a separate layer from execution nodes. This means that EVM is unable to access or store data within blobs, making Rollup the primary beneficiary of this upgrade. Data storage is now available in integer units of blobs, while regular transaction fees remain unchanged at 16 gas per non-zero byte and 4 gas per zero byte of calldata. Only transactions involving blobs will incorporate both gas fee markets.

Every execution shard can be tailored to accommodate different programs. However, recognizing the limitations and risks involved, Ethereum developers opted for data sharding to address the scalability issue of expanding Rollups using "blobs". Data blobs are processed, stored, and verified by consensus nodes on a separate layer, independent of execution nodes. This means EVM cannot access or store data in blobs, benefiting Rollups the most. Data storage is offered in integer units of blobs, with each blob equivalent to 128 kB. Pricing for using blob resources will fluctuate based on market demand, starting 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 if the number used is 3 or fewer.

@lina128907 such as Uniswap and Sushiswap have already integrated the new version, providing users with faster and more efficient transactions on their platforms.

Following the successful deployment of the upgraded version of Dencun, Layer 2 promptly rolled out the update. Several notable projects like zkSync, Starknet, Arbitrum, Base, and Optimism have introduced their updated versions. Many of these projects have seen a significant reduction in transaction fees for sending ETH, attributed to lower data storage costs. Each execution shard can be configured to support the execution of various programs. In light of constraints and risks, Ethereum developers have opted for data sharding to address the scalability issue of Rollups through the utilization of "blobs". Data blobs, processed, stored, and verified by consensus nodes, provide a distinct mechanism separate from execution nodes. The EVM does not access or store data in blobs, benefiting Rollups the most. Data storage is sold in integer units of blobs, while normal transaction fees remain unchanged, with calldata incurring a charge of 16 gas for non-zero bytes and 4 gas for zero bytes. Gas fee markets are only utilized for blob transactions.

@liz__azs Data sharding in Ethereum helps improve scalability by dividing data into shards to allow for more efficient processing and storage of information within the network.

@TheMatrixRecaga Executing different programs in each shard enables parallel processing, enhancing scalability. However, Ethereum developers are prioritizing data sharding for more efficient resource usage and transaction processing.

Each execution shard can be designed to run different programs. However, due to limitations, Ethereum developers are moving towards data sharding to address Rollups expansion issues via "blobs". Data blobs are processed, stored, and verified by consensus nodes independently from execution nodes. EVM cannot access or store data in blobs, benefiting Rollup the most. Blobs are sold in integer units, with one blob equaling 128 kB. Pricing depends on supply and demand, with standard pricing at 3 blobs/block (384 kB). Pricing increases by 12.5% for each additional blob used beyond 3, but decreases by 12.5% if 3 blobs or less are used.

Following the successful deployment of the Dencun upgrade, Layer 2 swiftly adopted the update. Leading projects such as zkSync, Starknet, Arbitrum, Base, and Optimism have all released updated versions. Many of these projects have seen a notable reduction in transaction fees for sending ETH, attributed to a significant decrease in data storage costs. While each execution shard can support different program environments, Ethereum developers opted for data sharding to address scalability concerns, using "blobs" to expand Rollups. These blobs, managed by consensus nodes independently of execution nodes, provide a unique benefit to Rollups. Notably, data storage space is now sold in integer units of blobs. Meanwhile, normal transaction fees remain consistent, with calldata charged at 16 gas/non-zero bytes and 4 gas/zero bytes. It's worth noting that only blob transactions utilize both gas fee markets.
