Setting up a multi-node network with Substrate

" summary

Walks through setting up a Substrate multi-node network with Aura and Grandpa consensus, showing exact subkey commands, generated node/aura/grandpa keypairs, and a modified chain-spec deployed to three geographically separate servers. Builds a runnable network of three validators (London, Amsterdam, Frankfurt), sees blocks produced and first seven blocks finalized, measures propagation ~23–50 ms, and exercises a custom NFT pallet (create, set price, buy, transfer) via polkadot.js — all steps, scripts and outputs are on the linked repo.
