Pinning vs. Endowment

While IPFS is excellent for decentralized routing, it requires "pinning"—nodes must actively choose to host the data, which often requires recurring payments to a pinning service.

Arweave, however, utilizes a unique economic model where an upfront payment acts as an endowment, covering the cost of storage in perpetuity. This makes Arweave the only logically sound choice for storing Digital Wills and permanent AI agent states.

Key Differences

  • IPFS — Content-addressed, requires active pinning, data can disappear if no nodes host it
  • Arweave — Blockweave-based, single payment for permanent storage, economic incentives ensure data persistence for 200+ years
  • Filecoin — Contract-based storage deals with expiration dates, requires renewal

Why Permanence Matters for Inheritance

Digital inheritance operates on generational timescales. A storage solution that requires monthly payments or periodic renewal fundamentally cannot serve as the backbone of a digital will. Only true permanence—guaranteed by economic endowment, not subscription—provides the assurance that your legacy will survive.
