Ethereum Layer 2 Scaling Solution


Inherits security features from Ethereum, uses Optimistic Rollups.

Optimism stands out as a Layer 2 scaling solution built on top of Ethereum. It utilizes Optimistic Rollups to bundle large amounts of transaction data off-chain, significantly improving speed and reducing costs compared to transacting directly on the Ethereum mainnet. Optimism’s focus on developer-friendliness and compatibility with Ethereum tooling makes it a natural choice for projects seeking to scale without drastically altering their codebase.


Utilizing Ethereum's Security

Optimism depends on the Ethereum blockchain for its ultimate security and decentralization. Transactions are bundled into batches off-chain, but settled periodically on Ethereum. This reliance on Ethereum’s security model offers reassurance for users and developers.

Details about Optimism security

  • Securing Optimism

    Contribute to the security and integrity of Optimism’s rollup mechanism as part of its Proof-of-Stake model.

  • Ethereum Inheritance

    Staking mechanisms likely aligned with Ethereum’s, providing a familiar experience for users.

Fees and ETH Usage

  • Reduced Transaction Costs

    Fees for transactions on Optimism are often significantly lower than those on the Ethereum mainnet.

  • Pay with ETH

    While Optimism doesn’t have a unique native token, transaction fees are paid in ETH.


Optimism Smart Contracts

Optimism is largely compatible with the Ethereum Virtual Machine (EVM), enabling a seamless transition for many Ethereum-based dApps. Developers can use familiar tools and languages (like Solidity) to build and deploy on Optimism. This compatibility lowers the barrier to entry and fosters a strong development community.

Details about Optimism smart contracts

  • Ethereum Scaling Solution

    Benefits from reduced fees and increased transaction speed while inheriting Ethereum’s security.

  • Optimistic Rollups

    Leverages optimistic rollups for scaling smart contract execution on Ethereum Layer 2.
