IPFS, CoinList, and the Filecoin ICO with Juan Benet and Dalton Caldwell

TL;DR

Protocol Labs builds IPFS (content-addressed peer-to-peer file system) and Filecoin (decentralized storage network with a native currency that mediates a storage market and uses proof‑of‑replication as a valuable side effect of consensus).

Key insights

  • IPFS shifts the internet from location‑based addressing (HTTP) to content‑based addressing, using cryptographic hashes so content is verified by what it is, not where it is.
  • Filecoin uses a proof‑of‑replication (“proof‑of‑storage”) as its consensus mechanism, so miners’ influence is proportional to the storage they provide to the network – a valuable side effect unlike Bi
  • The earlier “peer‑to‑peer winter” (circa 2003–2009) was driven by copyright‑infringement use cases, the rise of centralized cloud, and lack of a trustless digital currency to mediate markets.
