From IPFS/libp2p content addressing to Filecoin PoSt/PoRep, Arweave permanent storage, Storj erasure coding, Sui Walrus RaptorQ, BNB Greenfield, modular DA (EigenDA/Celestia/Avail), decentralized DBs (Ceramic/Tableland/OrbitDB), CRDT sync (Y.js/Automerge), distributed keys (Lit/Threshold), and data marketplaces (Ocean/Vana) — plus real-world use cases for NFT metadata, AI data DAOs, censorship-resistant publishing, and a decision matrix for choosing what to use when.

IPFS·libp2p의 콘텐츠 어드레싱부터 Filecoin의 PoSt·PoRep, Arweave의 영구 저장, Storj의 erasure coding, Sui Walrus의 RaptorQ, BNB Greenfield, EigenDA·Celestia·Avail의 모듈러 DA, Ceramic·Tableland·OrbitDB의 탈중앙 DB, Y.js·Automerge의 CRDT 동기화, Lit·Threshold의 분산 키, Ocean·Vana의 데이터 마켓플레이스까지 — 그리고 NFT 메타데이터·AI 데이터 DAO·검열 저항 퍼블리싱 같은 실전 쓰임새와 그 사이에서 무엇을 언제 쓰는지 결정하는 매트릭스까지.
