Methods and systems for a decentralized data streaming and delivery network

A tracker server system for distributing a data file within a decentralized data delivery network, comprising:

• at least one processor;
• and
• a non-transitory physical medium for storing program code accessible by the processor, the program code when executed by the processor causes the processor to:
• receive a client statistic from a first cacher peer node, wherein the client statistic comprises a first location of the first cacher peer node and a performance specification of the first cacher peer node, and wherein the decentralized data delivery network implements a hybrid architecture comprising one or more peer-to-peer (P2P) connections layered over a content delivery network (CDN) having at least one CDN server providing a first plurality of fragments of the data file to the first cacher peer node;
• send a caching instruction to the first cacher peer node to download a subset of the first plurality of fragments of the data file from the CDN server, wherein the caching instruction is generated based on the client statistic;
• receive a request from a viewer peer node in the decentralized data delivery network for accessing one or more target fragments of the data file;
• extract, from the received request, a content type of the requested data file, and a second location of the viewer peer node;
• generate a cacher peer list by selecting, from cacher peer nodes currently active in the decentralized data delivery network, one or more cacher peer nodes to provide access to the one or more target fragments of the data file, wherein at least one selected cacher peer node is selected based on the second location of the viewer peer node, a third location of the at least one selected cacher peer node, and the content type of the requested data file;
• and
• transmit the generated cacher peer list to the viewer peer node.
