Optimism is a Layer-2 scaling solution for Ethereum designed to enhance the Ethereum’s scalability and efficiency. It aims to help reduce the data load on Ethereum and lower transaction costs, making it ideal for decentralised applications (dApps) and decentralised finance (DeFi) platforms.
Note
Luno does not currently support sending or receiving OP, but you can still buy or sell it like any of our other cryptocurrencies. This decision has been made in order to ensure there are appropriate controls in place to maintain the highest standards of investor protection. Learn more about why you can't send or receive OP.
How does Optimism work?
Optimism enhances Ethereum’s performance using a technology called Optimistic Rollups. In this system, transactions are first processed outside of the main Ethereum network (this is referred to as “off-chain”). These transactions are grouped together into batches, and a summary of the batch is then posted back to the main Ethereum network (known as “on-chain”), where all transactions and smart contracts are recorded.
This approach reduces the amount of data and computation that needs to be handled directly by Ethereum, which leads to lower fees and faster transactions. The system assumes that all transactions are valid unless there’s a reason to believe otherwise, which means that transactions are only checked in detail if there’s a dispute. This method ensures efficiency while still relying on Ethereum’s security.
What is the native cryptocurrency of Optimism?
The native cryptocurrency of Optimism is OP. OP is used to pay for transaction fees and participate in governance within the Optimism ecosystem. It allows holders to vote on important protocol decisions, including upgrades and fund allocations, ensuring that the community has a say in the future development of the network. It’s also used to invest in the future success of the ecosystem.
Who created Optimism?
Optimism was founded by Jinglan Wang and Kevin Huang, who aimed to address Ethereum’s scalability issues by introducing a highly efficient Layer-2 solution. The project is developed by Optimism PBC, a company dedicated to improving Ethereum’s infrastructure through innovative scaling technologies.
Security incidents
Optimism has experienced the following security incidents:
Wintermute Liquidity Provision Exploit (May 2022): A hacker exploited a replay vulnerability to access 20.00 million OP tokens that had been sent to an incorrect address provided by the market maker Wintermute. The attacker eventually returned 17 million OP and kept 2 million as a bounty. Source: The Block
Mainnet Head Stalls (Various, 2024): Throughout 2024, OP Mainnet experienced "unsafe head stalls" where the sequencer was unable to produce blocks, leading to network pauses for several hours. These incidents occurred in February, April, May, June, July, September, and December. Source: Blockworks
Fault Proof System Vulnerabilities (April 2024): Offchain Labs identified two vulnerabilities in the OP Stack's Fault Proof System that could have allowed a bad actor to force the protocol to accept fraudulent chain history. The vulnerabilities were privately disclosed and fixed before public announcement. Source: Optimism
The above list of incidents may not be exhaustive. As always, it’s important that you do your own research to ensure you’re comfortable with an asset’s associated risks before investing in it.
Token supply and concentration
Optimism has a total supply of ~4.29 billion OP. As of December 12, 2024, the top 10 wallet addresses collectively hold ~2.75 billion OP (~64.10% of the total token supply).
