Incrementally aggregatable vector commitment techniques and applications to verifiable decentralized storage
Vector commitments with subvector openings (SVC) [Lai-Malavolta, Boneh-Bunz-Fisch; CRYPTO’19] allow one to open a committed vector at a set of positions with an opening of size independent of both the vector’s length and the number of opened positions.

Scaling proof-of-replication for Filecoin mining
A proof-of-replication (PoRep) is a proof system that a server can use to demonstrate to a network in a publicly verifiable way that it is dedicating unique resources to storing one or more replicas of a data file.

Proof of replication
We introduce Proof-of-Replication (PoRep), a new kind of Proof-of-Storage, that can be used to prove that some data D has been replicated to its own uniquely dedicated physical storage. Enforcing unique physical copies enables a verifier to check that a prover is not deduplicating multiple copies of D into the same storage space.
