Major players in the global computational ecosystem

1. Ethereum - A distributed global virtual computer over the internet integrated via a blockchain protocol.
2. Ceptre - A distributed computational ecosystem that integrates semantic computation, high level interoperability and data integrity scheme.
3. MaidSafe - a distributed and secure file system that comes to replace servers with p2p model. Aims at an application layer in the future.
4. IPFS - a p2p hypermedia protocol, that comes to replace servers with p2p model (Aims at an application layer in the future?).
5. Also, we should not forget the 'traditional' players, e.g. cloud computing utility providers. They hold enormous computing power and services which should not necessary be seen as 'competition' to the emerging technologies -- rather a leverage that can make them even more powerful.
