What is Optimism Crypto? The Simple Layer 2 For ETH Scaling

ICsues like transaction fees and scalability have always been a dilemma on Ethereum. But now you don’t have to be tired of these problems anymore as more and more Layer 2 projects appear. Optimism is arguably one of the best options out there and this ecosystem gets a lot of it. the attention of the Ethereum community recently. So through the following article, let’s find out what exactly is Optimism Crypto?

So, What is Optimism Crypto in Details?

Optimism or Optimistic Ethereum (OE) is a Layer 2 scaling solution that allows users to send transactions on the Ethereum network at much faster speeds and much lower gas fees than usual. The API of the Optimism network largely uses the same JSON-RPC specification as Ethereum, allowing users to build a fully functional application.

What is Optimism Crypto

To speed up transactions, Optimistic roll ups will not calculate transactions, but will use a fraud proof mechanism to ensure transactions are legit and avoid fraud. If someone notices a fraudulent transaction, rollups will perform anti-fraud and run the transaction’s computation, using available state data. This means that users can have a longer transaction confirmation time than ZK-rollup because transactions can be challenged.

Outstanding Features

Basically, users can send transactions on Optimism similar to Ethereum, but will get the following core benefits:

  • Transaction processing speed: Users can almost immediately know if their transaction is taking place or not.
  • Transaction fees are much lower than the Layer 1 solution: only 1% to 10% of the cost on Layer 1.
  • Scalability and dApp building: Full support for EVM. Ethereum-based dApps or EVM-compatible dApps can simply run on Optimism.
  • Decentralization: All transactions are posted to Layer 1 Ethereum, while inheriting the strong security guarantees of Ethereum.

Structure of the Optimism platform

Ethereum mainnet

This is the main foundation aka Layer 1 of Optimism.

Optimistic Rollup

This is the core to the extension of Optimism. Simply put, the Optimistic Rollup will aggregate a group of individual transactions on the Ethereum network into a single transaction. These transactions are then taken off the main blockchain for processing on a Layer 2 sidechain and sent back to Ethereum.

This mechanism will help reduce the transaction volume that Ethereum has to process, thereby reducing gas fees significantly.

Optimism Virtual Machine (OVM)

This is a virtual machine compatible with Ethereum, allowing projects to operate similarly to Layer 1. OVM is an environment to run Ethereum’s Smart Contracts, which can increase scalability compared to EVM to support processing. a large number of SmartContracts in a certain time.
