As the Ema in Japan, DMZ in Korea, John Lennon's wall, the Before I die walls etc. I wanted to propose a similar concept for hope messages.

a digital wall, accessible to everyone from everywhere, where people that want to share their optimism for the future can leave a message for those who might need it.

if you'd like to share a reason for why you're optimistic about the future, feel free. currently there are only messages in French, but any language is good
