A Blockchain Ecosystem is a new kind of market platforms that are collectively owned by the participants, not by a single platform provider. Amazon and Google are examples of platform providers. Platform providers own the platform making it difficult for participants to maximize the benefits of belonging to one.
A blockchain ecosystem by its nature makes it easy for large, disparate groups of market participants to communicate, collaborate and – most importantly – safely transact with each other. In a blockchain ecosystem, all participants can also observe the entire state of the market at any time, as opposed to in a proprietary platform, where only the platform owner has the full overview.
