What is GEX?

Galactic Exchange (GEX) is a global decentralized data exchange and market, where people and machines can publish, share and sell live data and message streams, as well as apps that process these streams.

Key concepts

Data is sent as messages transmitted over the TCP/IP protocol.

Apps read data streams, process them and post results back to GEX.

Nodes provide fixed amount of temporary storage for recent messages in each topic. Older messages are purged.

Subscribers establish TCP connections to one or many nodes, and get notified on new message arrival, as well as can retrieve recent messages.

Ai

Publishers publish data streams to one or many nodes. A data stream corresponds to a topic abstraction similar to a Twitter handle.

Payments are made in GEX tokens utilizing an Ethereum-based blockchain platform with micropayment channels. Both per-minute micropayments and longer-term smart contracts are supported. Prices are determined by an algorithmic market.

Data access can be free or paid through the algorithmic data market. Confidentiality and protection of paid data is achieved by clients encrypting messages before publication.

Service quality is enforced by nodes periodically submitting crypto proofs to the blockchain, as well as by clients continuously verifying node operation. Clients mine GEX by verifying nodes.
