Continuous Space-Bounded Non-Malleable Codes from Stronger Proofs-of-Space
Non-Malleable Codes Proofs of Space Tamper-resilience

Non-malleable codes are encoding schemes that provide protections against various classes of tampering attacks. Recently Faust et al. (CRYPTO 2017) initiated the study of space- bounded non-malleable ...
Tight proofs of space are necessary for proof-of-replication (PoRep), which is a publicly verifiable proof that the prover is dedicating unique resources to storing one or more retrievable replicas of...
PoReps: Proofs of Space on Useful Data

A proof-of-replication (PoRep) is an interactive proof system in which a prover defends a publicly verifiable claim that it is dedicating unique resources to storing one or more retrievable replicas o...
Beyond Hellman's Time-Memory Trade-Offs with Applications to Proofs of Space
Time-Memory Trade-Offs Proofs of Space Proofs of Work
2017/9/18
Proofs of space (PoS) were suggested as more ecological and economical alternative to proofs of work, which are currently used in blockchain designs like Bitcoin. The existing PoS are based on rather ...
On the Complexity of Scrypt and Proofs of Space in the Parallel Random Oracle Model

We investigate lower bounds in terms of time and memory on
the parallel complexity of an adversary A computing labels of randomly
selected challenge nodes in direct acyclic graphs, where the w-bit l...

We introduce a new cryptographic primitive: Proofs of SpaceTime
(PoSTs) and construct a practical protocol for implementing these
proofs. A PoST allows a prover to convince a verifier that she spent...
We propose a decentralized cryptocurrency called Spacemint, which is based on a block chain ledger similar to that of Bitcoin, but where the wasteful proofs of work are replaced by efficient \emph{pro...
Proofs of computational effort were devised to control denial of service attacks. Dwork and Naor (CRYPTO '92), for example, proposed to use such proofs to discourage spam. The idea is to couple each e...

Proofs of work (PoW) have been suggested by Dwork and Naor (Crypto'92) as protection to a shared resource. The basic idea is to ask the service requestor to dedicate some non-trivial amount of computa...
