On extensibility, Walrus processes a central 1.18 TB of shard elements across 60 days, with P90 at 1.08 TB, and 221.5 GB of meta details, P90 46.34 GB. As per the outline, nodes each supply 15-400 TB. The aggregate exceeds 5 PB, a vital Walrus trait. Illustrations reveal capacity scaling with committee expansion, affirming proportional growth to node count.For connections, resistance to suppression in storage and data propagation fueled early P2P trends and non-central emphases. Scholarly, Eternity in '96 aimed to prevent content vanishing. In practice, Napster, Gnutella, Free Haven, early Freenet used unstructured links for retention, paths, and provision, mainly files. They applied central or flood methods for searches; full duplicates on response routers. These yielded casual security with weak output.Later, 2000s work offered structured P2P via DHTs: Chord, Pastry, Kademlia, for better finds and reduced replication. DHTs work sans consensus or full sync. But susceptible: Sybils identified here; hard vs. routing threats. Current uses see attacks. BitTorrent prevailed in dissemination, from simplicity and incentives. Initially full copies, central trackers; later Kademlia trackers.Contrasting, Walrus holds a full, consistent node list via Sui blockchain, with fresh metadata. Assumes reliable nodes for rewards, low churn, protocol-based changes.Blockchain times, IPFS gives decentralized file hold, key for chains and dApps. Content-addressed blocks, DHT links replicas to hosts. Publishers pin for endurance, paid. Underneath, full replication on few per file.Filecoin enhances IPFS with chain, FIL to spur replica keeping. Users contract nodes, pay crypto. Mitigates drops via encoded copies, challenges. Encodings slow regen from originals, anti-relay. So, source retrieval waits decoding unless hot copies, extra cost sans incentives.Arweave fixes slow access with access-proof, rewarding wide holdings. With full replication, nears SMR levels. Forces forever storage, prepay, no flex for life/delete, capital waste.Versus them, Walrus erasure codes for 4.5x low overhead, survives 2/3 losses, operates with 1/3 down. Uses Sui for management/incentives, no own chain.Storj another encoded decentralized: Reed-Solomon 29/80, 80 parts, 29 recover, 2.75x factor.
