@ahin_1075 Superchain improves scalability on Optimism and OP Chain, like Cosmos does for interconnected blockchains.

The Superchain concept is revolutionizing scalability on the Optimism network and blockchains within the OP Chain ecosystem. Similar to Cosmos and Avalanche's subnet, Superchain aims to unite Optimism Mainnet with OP Chains to enhance internet-level scaling. Projects within the Superchain will utilize OP Stack solutions for deployment, simplifying the process of building Layer 2 blockchains. Additionally, Superchain projects will benefit from 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 permissionless protocols.

@sisocarol Superchain was formed by combining Optimism Mainnet and OP Chains to create a seamless scaling ecosystem.

Superchain was created by merging the Optimism Mainnet network with OP Chains to form one cohesive ecosystem for internet-level scaling. All Superchain projects will be on OP Stack for easier deployment and sharing of resources. The goal is to develop a decentralized web, replacing centralized entities with a permissionless protocol. Superchain is horizontally scalable, requiring participation from multiple blockchains to run in parallel effectively. This approach reduces systemic risks associated with traditional blockchain designs.

The Optimism Foundation envisions expanding the blockchain ecosystem towards a decentralized web, replacing centralized entities with permissionless protocols. Optimism's superchain proves to be scalable, horizontal, and dependent on the involvement of multiple blockchains. Synchronizing a blockchain aligns with the amount of computation it executes, requiring parallel operation to scale horizontally. The challenge lies in traditional designs which impose limitations - each chain employs a distinct security model, heightening systemic risk upon introducing new chains. Constructing new chains is costly, necessitating the creation of validator sets or producers. By amalgamating Layer 2 for a multi-chain ecosystem, resources can be interchanged as commodities. This empowerment enables developers to construct cross-chain applications without fretting over systemic risks.

@1NkT1 Multi-chain ecosystem enables seamless trade of assets across Layer 2 networks, revolutionizing decentralized finance.

The Superchain developed by Optimism is a horizontally scalable platform that involves the collaboration of multiple blockchains. The hardware needed to synchronize each blockchain increases proportionally with the computational tasks it performs, thus requiring parallel operation to scale effectively. However, conventional approaches face limitations as each chain introduces a new security model, heightening systemic risks. Constructing new chains is costly due to the need for establishing validator sets or producers from scratch. By integrating Layer 2 technology to establish a multi-chain ecosystem, resources can be freely traded between chains, enabling developers to create cross-chain applications without concerns about security risks. Superchain operates as a decentralized platform comprised of numerous blockchains sharing the same security model and technology stack (OP Stack). In this regard, its main competitors include Cosmos, Avalanche, and Polkadot ecosystems. Superchain stands out as a network of various L2 chains (known as OP Chains) with shared security, technology stack, and communication functionalities, allowing for standardized and seamless resource exchange. Developers can build applications that are compatible with the entire Superchain network.

The Optimism Foundation aims to enhance the blockchain ecosystem by creating a decentralized web – a new internet structure that eliminates centralized authorities in favor of open protocols. Optimism's innovative superchain is highly scalable, operating horizontally and relying on the collaboration of multiple blockchains. As a blockchain's computational demands increase, the hardware needed to synchronize it grows linearly. To achieve horizontal scalability, blockchains must run in parallel. However, existing designs have shortcomings. Each chain employs a unique security model, contributing to heightened systemic risk when new chains are integrated. The creation of new chains is costly, as it necessitates the establishment of validator sets or entirely new block producers. By integrating Layer 2 technologies to establish a multi-chain environment, assets on various chains can be exchanged like commodities. This enables developers to craft cross-chain applications freely without concerns about systemic vulnerabilities.

Some Layer 2 solutions like Scroll, Linea, Polygon zkEVM have not yet undergone upgrades, resulting in higher transaction fees compared to other Layer 2 solutions. Thanks to the recent Dencun update and the introduction of blob, the strain on the Ethereum network has been alleviated while maintaining essential features such as decentralization and security. Following the successful deployment of the upgraded Dencun version, various Layer 2 solutions including zkSync, Starknet, Arbitrum, Base, and Optimism have swiftly released updated versions. These updates have led to a noticeable decrease in transaction fees for activities like sending ETH, largely due to reduced data storage costs. Each execution shard can now support different program executions. Regular transaction fees remain unchanged, with calldata charged at 16 gas for non-zero bytes and 4 gas for zero bytes. Only blob transactions utilize both gas fee markets.

Every shard has the ability to run various programs, but Ethereum developers have chosen to focus on data sharding to address scalability issues instead of execution sharding. The introduction of data blobs allows for the expansion of Rollups, providing a solution to existing limitations. Data blobs are managed by consensus nodes on the consensus layer, separate from the execution layer. This means that the EVM cannot interact with or store data in blobs, benefiting Rollup groups the most. Storage space is measured in integer units of blobs, with each blob equivalent to 128 kB. The cost of utilizing blob resources is determined by market supply and demand, with the standard level set at 3 blobs per block (384 kB). Prices increase by 12.5% for each additional blob used beyond 3, and decrease by 12.5% if 3 blobs or less are utilized.

@jormanramirezz Layer 2 quickly rolled out the updated version of Dencun after a successful deployment, ensuring users could benefit from the improvements without wasting any time.

Following the successful deployment of the upgraded version of Dencun, 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 updates resulted in a significant decrease in transaction fees for sending ETH, as data storage costs saw a sharp decline. Each execution shard has the capability to support various programs. Nevertheless, considering the limitations and risks involved, Ethereum developers opted to pursue data sharding to address scalability challenges in Rollups through the use of "blobs". Data blobs are uniquely processed, stored, and verified by consensus nodes on the consensus layer, separate from the execution nodes on the execution layer. This setup means that the Ethereum Virtual Machine (EVM) cannot access or store data within blobs, resulting in Rollups being the primary beneficiaries of this upgrade. Data storage space is now traded in integer units of blobs, while regular transaction fees remain unchanged—calldata is charged at 16 gas for non-zero bytes and 4 gas for zero bytes. Only blob transactions utilize both gas fee markets.

@Ise_martinez These Layer 2 solutions are struggling with higher transaction fees as they have not received necessary upgrades to improve efficiency and scalability.

Some Layer 2 solutions such as Scroll, Linea, and Polygon zkEVM have yet to receive upgrades, resulting in higher transaction fees compared to their counterparts. However, thanks to the recent Dencun update and the introduction of blob, congestion on the Ethereum network has been alleviated while maintaining key attributes like decentralization and security. Following the successful deployment of the upgraded Dencun version, various Layer 2 solutions including zkSync, Starknet, Arbitrum, Base, and Optimism have swiftly updated their systems. These updates have led to a notable decrease in transaction fees for sending ETH, attributed to lower data storage costs. Moreover, the flexibility of execution sharding allows for diverse program executions within each shard. In terms of fee structures, standard transaction fees remain unchanged, charging 16 gas for non-zero bytes of calldata and 4 gas for zero bytes. Notably, only transactions involving blob utilize dual gas fee markets.

Blob is a novel data type created to offer short-term data storage for Ethereum applications, especially Rollup. The blob format enhances throughput and reduces costs compared to traditional calldata. Call data expenses are the key costs for Layer 2 projects, leading Rollup to spend 15,000 ETH solely on this. Initially, Ethereum focused on execution sharding but switched to data sharding due to limitations. NFT collections have their staking platforms.
