From https://news.ycombinator.com/item?id=33302599 : > If you label things with #GlobalGoal hashtags, others can find solutions to the very same problems. The Global Goals are the UN Sustainable Development Goals for 2015-2030. There are 17 Goals, 169 Targets and 247 Indicators. There have been social media campaigns with hashtags, so there are already "hames" (hashtaggable names) for the high level goals. Anyone can implement #hashtags, +tags, WikiWords, or similar. The twitter-text library is open source, for example.

: > Is there a way for sites to sign a claim with e.g. ld-proofs and then have an e.g. an independent auditor - maybe also with a W3C DID Decentralized Identifier - sign to independently verify? When an auditor confirms a sustainability report, they could sign it and award a signed blockcert. (Other ideas considered for similar matching, recommendation, and expert-finding objectives: A StackExchange site for SDG Q&A with upvotes and downvotes, ) I saw that you're not interested in (syndicating content for inbound links with) AT protocol? Is it perceived development cost and estimation of inbound traffic? What differentiates your offering from existing platforms like LinkedIn?
