Ethereum's scalability challenges hinder web3's mass adoption. As various teams seek solutions, layer 2 (L2) networks, particularly Optimism, have emerged as one of the leading solutions. Optimism employs optimistic rollups, which utilize off-chain computation and batched on-chain validation, to enhance Ethereum's transaction capacity.
The introduction of the OP Stack marks a pivotal step toward establishing a unified standard for L2 networks. This stack forms the foundation for the Optimism Superchain, a network of interoperable L2s built using the OP Stack. The Superchain aims to revolutionize Ethereum's scalability and interoperability. This blog examines the Superchain's architecture, functionality, and the projects built upon it.
What is Optimism Superchain?
The Superchain is a network of Layer 2 blockchain networks, all sharing a typical development stack (the OP Stack), communication layer, and security protocol. It facilitates horizontal scaling by enabling the creation of interconnected L2 rollup networks, known as 'OP chains,' which can communicate and function seamlessly as a unified system. This structure transforms Ethereum from a singular, often congested network into a vast, interconnected web of high-capacity, interoperable chains.
Advantages of the Superchain
Interconnected Efficiency: The Superchain facilitates smooth transactions across multiple sub-chains, significantly increasing the ecosystem's processing capacity.
Consistent Security: By adhering to a unified security protocol, the interconnected L2 networks maintain uniform trust and security across the Superchain.
Dynamic Scalability: The Superchain's design allows for the permissionless addition of new chains, ensuring continuous expansion without disrupting existing networks.
How Does the Superchain Work?
To understand the Superchain's operation, it is essential to grasp the fundamentals of the OP Stack, which forms the network's backbone.
OP Stack
The OP Stack structures blockchain systems into five distinct layers, each serving a specific role:
Data Availability Layer: Sources raw data inputs for the OP Stack-based chain, primarily through Ethereum DA.
Sequencing Layer: Manages the collection and relay of user transactions, typically by a single sequencer.
Derivation Layer: Processes raw data into inputs for the execution layer, primarily using rollups.
Execution Layer: Defines the system state and transition functions, with the Ethereum Virtual Machine (EVM) as the core module.
Settlement Layer: Allows external blockchains to view an OP Stack chain's valid state using attestation-based fault proof.
Law of Chains
The Law of Chains is a foundational framework for the Superchain, promoting decentralization and community collaboration. It outlines the rights and protections of stakeholders, balances unity with individual chain autonomy, and fosters shared growth.
Bedrock Upgrade
The Bedrock upgrade enhances the OP Stack with several improvements, such as reduced transaction fees, faster deposit confirmations, enhanced proof modularity, boosted node performance, and more significant Ethereum equivalence. These upgrades are crucial for the Superchain's efficient operation.
