So, I was thinking on tapes as a storage medium and remembered that Amazon Glacier exists (Amazon’s cold storage solution).
While Tardigrade currently don’t have a similar service it overlaps the idea of decentralised storage. The storage nodes logic would have to change and probably would need to have a different logic on audits and costs. While the current solution direct the income on traffic rather than the amount of storage, in a cold storage scenario the integrity of data is more important than the speed of retrieval.
This kind of service cold make sense in a resilient backup scenario, where clients would pay to left its data stored and untouched in the tardigrade network for years.
I believe that tardigrade still has room for improvements in the current service but this could be a possible next step.
