Whether you’re a seasoned Ethereum user or just getting started, this article has something for everyone. So read on and learn about the future of Ethereum with Optimism!

1. What is Optimism?

Optimism is a layer-2 scaling solution designed to enhance the speed and affordability of transactions on the Ethereum blockchain. It achieves this by processing the majority of transactions “off-chain” and settling them on the main Ethereum blockchain later. In essence, it acts as a shortcut that streamlines the entire system, resulting in lower costs, quicker transaction times, and a more user-friendly experience.

1.1. A Closer Look

Optimism, as a layer-2 scaling solution for Ethereum, focuses on improving the scalability of the network and reducing transaction fees. Founded by a team of developers committed to addressing Ethereum’s scalability issues, Optimism introduced Optimistic Rollup technology, a key component of the Optimism solution. The launch of the Optimism Ethereum mainnet in March 2021 marked a pivotal moment, with numerous decentralized apps exploring integration with Optimism.

1.2. The Purpose

Optimism tackles key challenges faced by blockchain networks, particularly Ethereum:

• Scalability: By reducing congestion and increasing transaction throughput, Optimism enhances Ethereum’s scalability. Optimistic Rollups play a vital role in achieving this.
• Reduced Gas Fees: The use of Optimism significantly lowers gas fees on the Ethereum network, making it more cost-effective for users to engage with decentralized applications (DApps).
• Enhanced User Experience: Optimism reduces transaction costs and improves transaction confirmation times, leading to an improved overall user experience.
• Interoperability: Optimism is designed to be compatible with existing Ethereum smart contracts and DApps, ensuring interoperability between the two.
• Security: It maintains a high level of security by relying on Ethereum’s security model as a settlement layer.

In essence, Optimism’s purpose is to make blockchain networks, like Ethereum, more scalable, cost-effective, and user-friendly.

1.3. OP token

OP is the native governance token of Optimism, providing token holders with the ability to participate in the governance of the Optimism network through the Optimism Collective. OP tokens can be acquired through exchanges, trading platforms, airdrops, or by actively engaging with the Optimism ecosystem. The primary purpose of OP tokens is to grant holders voting rights on proposals and changes to the Optimism network.

These tokens adhere to the ERC-20 token standards on the Ethereum blockchain. Governance functions are facilitated through the Optimism Collective, a Decentralized Autonomous Organisation (DAO) comprising the Token House and the Citizens’ House.

1.4. OP Airdrop

Optimism completed its airdrop 1 in May 2022. Over 200 million $OP was airdropped to an approximate of 248,699 addresses. The amount ranged from 409.42 up to 27,534.98 $OP. The criteria used for the eligibility for the airdrop were:

• Optimism active users
• Repetitive Optimism users
• DAO voters
• Gitcoin donors on L1
• Multisig Signers
• Users priced out of Ethereum

After a successful OP airdrop 2, the chances of OP airdrop 3 are high!

Airdrops are like giving free tokens as gifts that come from crypto projects. To get these gifts, one must meet a certain set of conditions specific to a currency. These tokens are dropped into the wallets of the chosen ones. Then, they can be used for keeping,trading or using them for any specific purpose. Airdrops are fun ways to earn bonuses for being a loyal crypto user.

2. How Does Optimism Operate?

Optimism is a Layer 2 scaling solution aimed at enhancing Ethereum’s performance. It achieves this through the use of Optimistic Rollups technology as the Layer 2 solution provider. The key steps in how Optimism operates are as follows:

• Transaction Bundling: Optimism bundles multiple transactions together, reducing congestion on the main Ethereum network.
• Fast Transaction Processing: Initially, transactions are considered valid with minimal verification, expediting the transaction process.
• Fraud Proofs: Validators can submit “fraud proofs” if they identify any discrepancies or issues.
• Reduced Gas Fees: Optimism significantly reduces gas fees, making the system more cost-effective for users.
• Ethereum Compatibility: It ensures compatibility with existing Ethereum smart contracts and DApps.
• Security Assurance: Optimism maintains a high level of security by relying on Ethereum’s security as the settlement layer.

3. The Advantages of the Network

Optimism offers a range of benefits, including:

• Enhanced Scalability: Optimism increases Ethereum’s transaction processing capacity, handling multiple users without causing congestion.
• Reduced Gas Fees: Using Optimism leads to a significant reduction in gas fees, making DeFi and other activities more affordable.
• Faster Transaction Confirmations: Transactions on Optimism enjoy quicker confirmation times compared to the Ethereum mainnet.
• Ethereum Compatibility: No code changes are required as Optimism is fully compatible with Ethereum smart contracts and DApps.
• Security: Optimism leverages Ethereum’s security to maintain a high level of safety.
• Improved User Experience: Reduced fees and faster transactions lead to a more favorable user experience.
• Interoperability: Optimism enables smooth asset transfers between Layer 1 and Layer 2 solutions.
