I am building a search engine using open source utilizing lucene and elasticsearch and others.
I am looking to add blockchain technology wherever I can. I am looking for someone inventive to explain to me in writing how we can use blockchain, from tracking members to using our own email system, to using memory for blockchain, accepting payments or using blockchain in accounting practice. You are the expert. I am looking for someone to give me a good blockchain explanation so my investors who love the blockchain can feel excited.
