Vitalik on Making Ethereum Great Again: Adoption, Security, and the Rise of Safer DeFi Video Source:

Vitalik, co-founder of Ethereum, responded to the question "How Can We Make Ethereum Great Again" by stating that there are two core goals: to achieve large-scale adoption and to continuously maintain high security and decentralization.

However, current data shows that the proportion of DeFi hacking losses to the total locked-in value has dropped below 0.53%.
