What is Proof of Space?

🎯 Goals

1. New PoS Research
1. “more” tunable security
2. better retrievaility
1. faster retrievability
2. local retrievability (to retrieve D[j] at position j one should not necessarily look at the whole file D)
3. at least as much efficiency or better efficiency (or substantial tradeoffs) than current constructions in terms of, among others
1. sealing time
2. chain footprint
3. auditing time
4. verification time

If the above fails, build a strong understanding of what the challenges are and effectively communicate them to stakeholders.

2. Educational
1. Formalising PoS
2. Knowledge sharing
3. Outreach to community
4. State Open Problems

👥 Team
