View ChartOptimism is an Ethereum Layer 2 scaling solution that uses optimistic rollups to deliver faster transactions and fees up to 100 times lower, while leveraging Ethereum’s security. Thanks to its seamless EVM compatibility and growing support from major DeFi apps, Optimism is making crypto more affordable and accessible for everyday users and developers alike.
At its core, Optimism uses a technology called “optimistic rollups” – a straightforward concept with a simple premise:
The magic happens through a mechanism called fraud proofs. Rather than verifying every transaction immediately (which is slow and expensive), Optimism assumes all transactions are legitimate. If someone spots a fraudulent transaction, they can submit proof and the invalid transaction gets rejected.
The result? Up to 100 times lower fees and dramatically faster transaction times compared to using Ethereum directly.
The Optimism ecosystem has its own token called OP, which serves several key purposes:
Unlike some cryptocurrencies, OP isn’t meant to be a currency for everyday purchases. Instead, it gives holders a say in how the network evolves.
The easiest way to buy Optimism (OP) is through a crypto exchange like BTCC. BTCC makes purchasing Optimism (OP) easy and accessible whether you use fiat currency or crypto.
