Will Your Digital Creation Disappear? Use Blockchain Proof of Existence to Record Your Presence Forever

12.8% of NFTs have already been permanently lost. Cloud storage is a rental model — stop paying and your work vanishes. This article explains how Proof of Existence uses Merkle Trees and Arweave to permanently preserve your creations, and how to create your first proof in 5 minutes for free.

Choosing Your Proof Type: Standard vs Perpetual

Standard Proof is free and batches your trail on-chain daily with no NFT. Perpetual Proof mints an ERC-721 NFT instantly, writes data to Arweave, and costs $2–$20 depending on trail length. This guide explains the difference and how to mint using POL, TIME26, or unclaimed balance (gasless).

Stories

Why Proof of Existence?

Proof of Existence is a year-long collective art experiment running through 2026. Participants draw light trails on a shared 3D canvas, recorded on Polygon via daily batch settlement and stored permanently on Arweave. The canvas seals on January 1, 2027 — becoming a permanent digital archive.
