Hi everyone… 
I am new to the Optimism ecosystem and have been finding its potential for scaling Ethereum. I have read about its use of optimistic rollups to reduce gas fees and increase transaction throughput, but I had love to move deeper.
Specifically, I am curious about:
- How Optimism ensures security while processing transactions off-chain.
- The role of fraud proofs in maintaining trust and how frequently they are challenged.
- Any notable dApps that are making the most of Optimism’s scaling solutions.
I check this: https://gov.optimism.io/t/links-to-help-understand-optimism-maybe-useful-before-considering-chasalesforcedeveloperonlinecourse But I have not found any solution. Could anyone guide me about this? I had also love to hear from those who’ve deployed smart contracts on Optimism—what was your experience like compared to deploying on Ethereum directly?
Looking forward to learning from the community and contributing as I get more familiar.
Thanks in advance!
Respected community member!
