A work spreadsheet is a document saying who needs to do what and when, so if work has not been done, people know who to talk to. Instead of using paper, it uses computer programs and cryptography, automating this process. This way, we achieve a common goal (clean house) and this works even if we have different incentives. A blockchain is a system that: is immutable, is transparent, is resistant to malicious actors, is auditable, and is transparent. It will thrive as a decentralizing technology, but there are lots of different use cases.
