In March 2023, the Ethereum scaling network Optimistic which operates as a layer 2, announced its plans to enhance the network. The upgrade, named “Bedrock”,  intends to improve transfer speed, reduce costs, and improve interoperability with the Ethereum Virtual Machine (EVM). Hence, today Tokenize Xchange – Blockchain Trading Platform will help you answer questions about Optimism and its upcoming upgrade.

What is Optimism (OP), How Optimism can solve the scalability issue, and How the Bedrock upgrade is going to affect OP price? Let’s find out with Tokenize Blog!

What is Optimism? 

Optimistic is a Layer 2 scaling solution on Ethereum that is driven by Optimistic Rollups, a method that bundles massive quantities of transaction data into manageable batches helps reduce gas fees, and speed up transaction completion, thereby providing a smoother user experience while preserving the security of the original Ethereum chain.

How Optimism can solve the scalability issue for Ethereum?

To begin with, we need to go through the blockchain trilemma to understand the scalability issue of Ethereum. 

blockchain trilemma

The blockchain trilemma is a theory that indicates the interaction of three objectives including security, scalability, and decentralization of a blockchain. Hence, it is impossible to maintain all three properties at a specific period of time. A blockchain commonly can perform two out of three of those. 

To confront this problem, the industry has come up with Layer-2. The Layer 2 solutions will interact with the Layer 1 blockchain to help solve some of the problems related to scalability. In other words, Layer 2 chains do not replace present blockchains. Although layer 2 chains would perform the majority of the work, layer 1 acts as the primary chain and provides security, while layer 2 provides rapid transactions, low transaction fees, and the potential to handle thousands of transactions per second.

So, how can Optimism solve the scalability issue of Ethereum? 

The answer is the advanced data compression technique called Rollup. 

The name “Rollup” refers to the process of splitting transactions off the main chain, then wrapping them in a single batch and creating proof, then uploading it to Layer 1. After so many transactions are combined into a single transaction, the “gas” fee is reduced to only one transaction, which is shared among all parties involved.

Moreover, to prevent invalid state transitions from occurring, Optimistic Rollup uses fraud proof. Simply put, fraud proof allows all transactions to be considered valid and approved unless it is proven to be false, in other words, innocent until proven guilty. Individual transactions do not need to be submitted with direct proof of their validity, hence, it saves time and fastens the network. Validators in the rollup have one week to query the entire rollup if they suspect false data.

Meet Optimism team

The team behind Optimism is the Optimism Foundation which is a nonprofit organization dedicated to running the ecosystem and growing the Optimism Collective. The Optimism Foundation is led by the two founders of Optimism, Jinglan Wang and Ben Jones, joined by Eva Beylin (Director of Graph Foundation), Abbey Titcomb (Head of Community of Radicle), and Brian Avello from the Maker Foundation.

According to, the Optimism Collective is a fresh approach to properly rewarding those who create or sustain public goods. The Optimism Collective is a group of businesses, communities, and citizens who have agreed to defend the fairness ratio: Impact = Profit. The Collective is divided into two Houses: the Token House and the Citizens’ House. These houses must strike a balance between long-term goals and short-term incentives.

What is Optimism token (OP) – The native token of Optimism

Optimism’s native token $OP coin is utilized for governance, voting for protocol updates, airdrop incentives, and ecosystem finance. $OP is ranked 82 in terms of trading volume with the price at $2.82 at the time of writing. 

Optimism introduced its OP token on May 31 2022. A total of 231,000 addresses were eligible for a free airdrop of 214 million OP tokens. This represents 5% of the total 4.29 billion supply, implying that 95% of the supply has yet to reach the market. 

Optimism to upgrade to Bedrock

Optimist, an Ethereum layer 2 scaling system, will be launching a major upgrade in March 2023 with the goal of lowering transaction costs, increasing transaction speed, and improving interoperability with the Ethereum Virtual Machine (EVM).

What is bedrock upgrade

Bedrock also acts as the foundation for Cannon, Optimism’s next-generation fault-proofing solution. Developed by Optimism and geohot, Cannon will be implemented to maintain Optimism’s ease and security. After the release of Bedrock, an Alpha version of Cannon is planned for release.

The “Bedrock” upgrade will add an important improvement to the network. 

Optimism first tweeted in early February that it was revising the requirements for the March 15 Bedrock upgrade. Nevertheless, a few weeks later, the Optimist Foundation announced that the vote on the upgrade will be moved to March 2-April 5 due to issues discovered in the code revisions.

OP Token, Optimism’s token, surged by 44% in February as a result of the Bedrock upgrade on Feb 2nd.
