A decentralised, user-operated content distribution network leveraging the power of users’ mobile devices and device to device connectivity.
A Bleeding Edge CDN
DataHop is a decentralised content distribution network that operates at the network edge.
DataHop bypasses the network core and utilises user smartphone and WiFi access point devices to distribute heavy content at the edge of the network - where users actually need it.
A Smart Connectivity Solution
DataHop utilises direct Device to Device (D2D) connectivity between
smartphones themselves as well as between Devices and WiFi Access Points to
prefetch video content to users’ devices.
Our smart connectivity solution, which is based on Bluetooth and WiFi Direct,
guarantees seamless and privacy-preserving D2D communication between users in the vicinity.
A Way to Reduce Costs
DataHop reduces cellular traffic for the mobile network operator,
streaming cost for the end-user and distribution cost for the content
provider. By utilising users’ devices, DataHop does not need to
maintain expensive CDN infrastructure.
Instead, building on blockchain
technology and novel Proof-of-X consensus algorithms, DataHop rewards
users for their contribution to the content delivery network.
It is impossible to prove (securely, privately and deterministically) that a D2D transfer has happened.
We therefore, designed a sophisticated Proof-of-Transfer consensus algorithm, based on Progressive Mining. Effectively, receiving devices send a certificate to the sender after receiving the content.
As nodes move, they form distribution trees of content transfers. In Progressive Mining, nodes are not rewarded for transferring content to their immediate encounters only, but they also get rewards for subsequent transfers in their respective distribution trees. The longer the distribution tree, the more the reward that users are entitled to.
Nodes eventually upload their activity to the blockchain to verify transactions and update their reward balance.
Our whitepaper contains all the necessary technical details on the design and implementation of the individual DataHop parts.
Coming Soon.
