Permanence score

A+Permanence
100/ 100

Exemplary. Backed onchain and mirrored across every independent permanent network.

  • Onchain proof (ethfs)
  • Content hash matches record
  • Redundant permanent copies4 of 3+
  • Shards locked (immutable)

In plain terms · The grade weighs the onchain proof first, then how many independent permanent copies back it up (4 here) and whether the shards are locked. The onchain proof alone guarantees survival; redundancy makes it effortless.

Proof

The vanish test

Take Perpetual offline and watch the artwork refuse to disappear. We shut down the indexer, the CDN, then even the IPFS pin, while the onchain proof keeps resolving the work from Ethereum itself.
