Comprehensive introduction to the OP coin project

1. Project introduction

Optimism is the first Ethereum L2, leading the development of Ethereum Virtual Machine (EVM) compatible Optimistic Rollup solutions.

2. Project Vision

A scaling solution to reduce the load on the Ethereum network. The actual execution of transactions is not done on the Ethereum blockchain, but is moved to Layer 2 ("L2 ")superior.

3. Market demand

Increase TPS to solve congestion problems and low gas fees for transfers.

4. Project Solution

Optimism is a layer 2 scaling solution used on Ethereum, its main feature is to make transactions on Ethereum applications very cheap. By moving transactions from one blockchain to another, miner fees are significantly reduced and throughput is increased. Optimism provides Ethereum developers the opportunity to use all the tools available on Ethereum without making changes.

5. Token usage scenarios

Distribution of community governance, voting rights, and project incentives.

6. Competitors Similarities and Differences

Optimism and Arbitrum are both OptimisticRollup, so they are similar in many aspects. The main difference lies in their fraud proof system. Optimism opted for a non-interactive fraud proof, which re-executes the entire transaction instruction and performs the required calculations on L1 to obtain the result. ZKRollup is another mainstream 2-layer expansion solution on Ethereum, using validity proofs. ZKRollup has zksync and starkware

7. Technical features

Optimistic Rollups use different types of proofs: fraud proofs. As the name suggests, OptimisticRollups are "positive and optimistic" because when they publish updated state to the Ethereum blockchain, they do not publish any "proof" at all. Anyone can publish a Rollup block that contains a statement about the correct result of executing a certain transaction, and other nodes executing the same transaction can challenge it as long as they disagree with the first node's assertion. An effective dispute agreement can resolve any disagreements, ensuring that the right party will win the challenge. Parties have strong incentives to publish only correct claims rather than challenge incorrect claims, so in the common case all nodes will "simply" execute all transactions and the proof code will never need to be called - the entire process is handled by The Layer1 contract is responsible for management.

I hope that through this article, everyone can figure out how to trade and buy OP coins. OP coins were also issued in anticipation of many investors. Optimistic, a leading Ethereum Layer-2 solution, aims to give its users more power and control over their ecosystem. To achieve its goals, Optimism adopts a unique bicameral governance model consisting of Citizen's House and Token House that jointly form the Optimism Collective, in which two different entities will work together to develop the ecosystem. The project's Citizen's House will arrive later in 2022, and will assume responsibility for allocating retroactive public goods funds.
