Optimism Blockchain Explained: A Comprehensive Guide

Optimism blockchain is a Layer 2 scaling solution that aims to increase the scalability and usability of the Ethereum network. It's built on a rollup architecture, which allows for the batching and compression of multiple transactions into a single transaction.

Optimism uses a technology called optimistic rollups to achieve this, which involves bundling multiple transactions together and then verifying them on the Ethereum mainnet. This process reduces the number of transactions that need to be processed on the mainnet, thereby increasing the network's scalability.

The Optimism blockchain has a native token called OP, which is used for transaction fees and governance. The token is also used to incentivize validators to participate in the network and secure the Optimism blockchain.

Mainnet is a Layer-2 rollup blockchain built for scaling the Ethereum blockchain.

It launched in 2022 for mass adoption, designed to increase Ethereum's transaction throughput and lower transaction costs.

Mainnet uses "optimistic" rollup technology, which assumes that all transactions contained within a rollup are valid.

This optimistic approach is fast because it doesn't need to waste time confirming each transaction individually.

However, it usually takes about a week to officially withdraw on-chain funds.

Blockchain is a distributed digital ledger that allows for secure, transparent, and tamper-proof data storage and transfer. It's a decentralized system, meaning that no single entity controls it.

Each block in the blockchain contains a unique code called a "hash" that links it to the previous block, creating a permanent and unalterable record. This is what makes blockchain so secure.

Optimism's blockchain is built on top of the Ethereum network, using a technology called Optimistic Rollups to reduce gas costs and increase scalability.

Scalability is a major concern for Ethereum, but OP Mainnet has a solution. It can scale transaction throughput up to 100x the Ethereum mainnet.

OP Mainnet's rollup solution batches transactions to achieve this impressive scaling. This is a significant improvement over the current state of Ethereum, which operates at a relatively slow pace.

Currently, OP Mainnet can process transactions at about 2,000 per second, while Ethereum manages around 10-12 transactions per second.

Smart contracts play a crucial role in blockchain applications, especially when dealing with people's money. Most blockchain applications involve financial transactions, so it's essential to prioritize security.

OP Mainnet makes it easier for smart contracts to be properly audited by allowing developers to leverage the systems put in place to test dapps on Ethereum directly. This is a significant advantage, as it ensures that smart contracts are thoroughly vetted before deployment.

The OP Mainnet Virtual Machine (OVM) shares the same level of on-chain security as the Ethereum Virtual Machine (EVM), providing a high level of protection for smart contracts. This equivalence ensures that smart contracts on OP Mainnet are just as secure as those on Ethereum.

The L1 security fee on OP Mainnet is calculated by multiplying the fee scalar with the gas price. The fee scalar is 1.

This fee is also known as the Layer 1 Gas Fee, which is the amount of gas used by a transaction when its data is published to the Ethereum mainnet.

The L1 security fee can be calculated using the formula L1 Gas Fee = Fee Scalar * L1 Gas Price * (Calldata + Fixed Overhead). Calldata is the input data of a transaction.

In some cases, the standard cost of gas on OP Mainnet is only 0.001 gwei, making OP Mainnet a far cheaper network for most users and dapps.

Smart contract security is a top priority for any blockchain application that deals with people's money. Most blockchain applications involve financial transactions, so it's crucial to build them with care.

Developers can now piggyback on the systems put in place to test dapps on Ethereum directly, making it easier for smart contracts to be properly audited. This is a game-changer for ensuring the security of smart contracts.

The OP Mainnet Virtual Machine (OVM) is equivalent to the EVM, sharing the same level of on-chain security. This means that smart contracts on OP Mainnet have the same level of security as those on Ethereum.

The OP Mainnet rollup uses a technique called Fraud Validity Proofs to verify data on its network. This approach assumes all transactions and activities on its protocol are true for a period of time, known as the Challenge period, which takes approximately seven days.

The Challenge period allows for a delay between the initial assumption of transaction truth and the final verification on the Ethereum network. This delay is a key aspect of the Fraud Validity Proofs mechanism.

The Fraud Validity Proofs mechanism is a novel approach to validating the legitimacy of on-chain transactions. This mechanism is one of the major reasons to consider building dapps on OP Mainnet.

This approach provides an added layer of security and confidence in the integrity of transactions on the OP Mainnet network.
