Optimism is an ecosystem of layer-2 chains that offer faster and cheaper transactions compared to the main Ethereum blockchain. It includes the original OP Mainnet, which is currently the world's second-largest layer-2 network in terms of value deposited.
Optimism relies on a technology called "optimistic rollup" to settle transactions to the main Ethereum blockchain, also known as the layer-1 or L1 blockchain. This technology allows for efficient and secure transaction processing.
In October 2022, developers at OP Labs, the creators of OP Mainnet, introduced the OP Stack. This new development enables developers to build their own blockchains within the Optimism ecosystem.
Optimism provides a solution for faster and cheaper transactions on the Ethereum network. With its layer-2 chains and optimistic rollup technology, it offers an efficient and secure way to process transactions. Developers can also take advantage of the OP Stack to create their own blockchains. Embrace the power of Optimism and unlock the full potential of Ethereum!
