Details are described in our research documentation.

The plan is to understand what should be done by us. Create a more granular tasks based on the resarch.

The libp2p protocols that should be implemented under the "libp2p Protocols" umbrella term will not communicate with the substrate directly. They are defining a communication part for the provider and client to exchange data like market asks and the actual file transfers over the p2p network. These protocols should be used by the storage client and provider implementation.

libp2p Protocols:

• Market protocol: implement Storage Query protocol #156
• Market protocol: implement Storage Deal protocol #157
• [SP Node] Market protocol — implement Data Transfer protocol #158
• Market protocol: implement Status protocol #159

Discovery phase:
In the discovery phase the client should first fetch all registered storage providers from the blockchain. That can be achieved by using a storagext-cli #160. One of the things that a client gets with this call is the provider's peer id. the peer id is needed for all p2p communications. After the list is received, the client should query #156 providers for their storage ask. The storage ask specifies the conditions under which the provider might accept a deal. The discovery phase for the client part should be possible with our storagext-cli. For the provider part we would need to implement the storage ask request handling (todo: task specific for the provider part).
