Proposals worthy of support 
1. Support the direction of the proposal: ArbitrumDAO sponsoring Attackathon helps both Ether and Arbitrum security. Ether’s security directly affects Arbitrum, so it’s a win-win.
2. Clear goals and transparency: The proposal has clear targets for the number of participants and the number of reports, and there will be regular reports to the community, so transparency is good.
3. Funding allocation: Immunefi waived fees and ensured that all funds were used to reward security researchers, which was good. And it makes sense that the remaining funds are used to support other auditing programs.
Suggestions:
1-. more AMA or community discussions could be organized so that more people can participate and understand the progress.
2-the education component was well done, and it is recommended to find ways to expand the impact of this to more security researchers.
