How exciting! I want to get started this week or next on building out the basic data structure with Merkle trees. I don’t think this will take too long, but I have been distracted with other things 
Yes, the cryptography aspect of blockchain is what makes it so compelling for financial tech (FinTech) and other enterprises wishing to keep their data secure and auditable. Apache Kafka can serve a similar function but its log data are not hardened with Merkle trees, there is no access control, and no encryption in motion.
I noticed there is already a project called ex_chain for Markov chains. To avoid confusion, should we change the name? Any suggestions?
