Ecosystem Applications are a new category of decentralised computer software application where the creation, ownership and running of an application is shared between all players in an ecosystem in such a way as it allows all players to write data to a shared decentralised data store or ledger, even when there are low levels of trust between players/participants.
Built using Blockchain and Smart Contract technology, Ecosystem Applications allow business sector participants in an ecosystem to create and share the software tools they uses rather than relying on a single organization to create and own such systems.
