OP Stack is a standardized, shared, and open-source development framework, combined with Gelato RaaS, it enables developers to deploy their own Optimistic Layer 2 chains, specific to end-users needs on Ethereum. By utilizing optimistic rollups, developers can take advantage of near-zero computational overhead, fast throughput, low transaction costs, and improved EVM compatibility. This powerful combination prioritizes key business operations and user interaction, ensuring optimal performance through adaptable L2 chains.
Optimism Bedrock is the current iteration of the OP Stack. The Bedrock release provides the tools for launching a production-quality Optimistic Rollup blockchain.
OP Stack Features
90% lower than Ethereum's gas fees, Bedrock achieves this reduction by optimizing data compression to cut costs and eliminate gas expenses for EVM execution.
With a 2-second block time compared to Ethereum's average of 12 seconds, Optimism ensures significantly faster transaction confirmations.
Enhanced Proof Modularity
Bedrock's design allows rollups to use various proof systems, like fault or validity proofs, providing flexibility for technologies like Cannon to verify correct execution.
Bedrock aims for high compatibility with Ethereum, offering developers a familiar experience by allowing the running of smart contracts and dApps designed for Ethereum without modification and utilizing existing Ethereum tooling and infrastructure.
Improved Node Performance
Execution of multiple transactions in a single rollup block and removal of technical debt from previous versions improve node software performance.
The Superchain is a future development by Optimism, envisioned as a network of Layer 2 chains (OP Chains) built on the OP Stack. These OP Chains will share security, a communication layer, and a technology stack, but will be standardized and interchangeable, differing from traditional multi-chain designs. It's a concept and in-progress project aimed at merging Optimism Mainnet and other chains into a unified network, enhancing scalability and decentralized computing.
Independent Data Availability
Gelato provides support for Optimium, a dedicated data availability layer for OP Stack that offers robust off-chain data access. It enables the launch of high-throughput and very low-cost, optimistic-powered Layer 2 chains on the Ethereum network.
