What is Optimism (OP)?
Optimism is a layer 2 scaling solution for Ethereum that was launched in 2022. It is the second largest rollup chain at the time of writing, following Arbitrum, with $857.1 million in total value locked. The chain introduces a new rollup mechanism called optimistic rollup, which has been so useful that other rollup chains such as Arbitrum and MetisDAO have adopted this mechanism.
How Optimism (OP) Works
At the core of the Optimism blockchain is the optimistic rollup mechanism. It has that name because all transactions when bundled and submitted to layer 1 are considered valid until proven otherwise. Validators of layer 1 can challenge potentially invalid transactions, and if the transactions are proven invalid, gas fee for running the fraud proof is reimbursed and the layer-2 nodes executing that transaction are punished.
The fuel that drives the growth of Optimism is the OP token. It powers both the governance and use cases of the blockchain.

Macau (or Macao) is a city in southern China which is also a special administrative region and very close to Hong Kong, with a population of 682,300. Macau is one of the most famous resort cities in the world and is famous for its gambling industry. That’s the reason why Macau was called the “Las Vegas of the East”. The currency of Macau is the Macanese pataca (MOP), which is pegged to the Hong Kong dollar at a fixed exchange rate of HK$1 = MOP 1.03.
Macau has been a Portuguese colony since 1557, and back then it was one of the most important trading ports in Asia. With the signing of the 1987 Joint Declaration on the Question of Macau between Portugal and China, Portugal agreed to transfer Macau back to China in 1999. Macau has combined both Chinese and Portuguese cultures. The remains of St. Paul's Cathedral, Senado Square, and A-Ma Temple are some of the most famous attractions in Macau.
Chinese and Portuguese are the official languages of Macau, and the Bitget app and website are available in both Chinese and Portuguese. In any place in Macau, there is no better place to buy Optimism(OP) than right here with Bitget, which has already acquired the U.S. MSB License, Canada MSB License, and Australia (DCE) License.
