Swarm / Replication

[mkg20001]

Libp2p swarm using p2p-stardust

Replication:

• New events announced via pubSub
• Previous data / Current data is always fetchable from other nodes via RPC
• Figure out a way to most reliably get latest block / ask for it when node has been offline for some time

Current swarm architecture

• MDNS, TCP, WS

Planned swarm architecture

Node:

• nodetrust extension
• transport: TCP, WS, stardust
• discovery: stardust, nodetrust
• pubsub: gossipsub

Browser:

• transport: WS, stardust
• discovery: stardust, nodetrust
• pubsub: gossipsub

This is blocked by the libp2p async iterator endeavour

Current & planned bitswap concepts

Server:

• [x] blockDepth for actions to fetch N blocks in chain of that action (needs a temporary chain storage map so we know which block is the previous of X without loading X)

Client:

• TODO
