How is blockchain being used for social impact initiatives?

[Steven55]

I'm researching blockchain for social impact and I'm curious about practical implementations. I've seen projects focusing on transparent aid distribution, fair trade certification, and refugee identity management. What blockchain for social impact projects have you come across that are actually making a difference? I'm particularly interested in cryptocurrency innovation 2025 that addresses social challenges, not just financial ones. How are decentralized applications solving problems in the social sector?
