ALGORAND: The Efficient and Democratic Ledger

Algorand is a truly decentralized, new, and secure way to manage a shared ledger. Unlike prior approaches based on proof of work, it requires a negligible amount of computation, and generates a transaction history that does not fork with overwhelmingly high probability. This approach cryptographically selects —in a way that is provably immune from manipulations, unpredictable until the last min...

A Fast Publicly Verifiable Secret Sharing Scheme using Non-homogeneous Linear Recursions

A non-interactive (t,n)-publicly veriable secret sharing scheme (non-interactive (t,n)-PVSS scheme) is a (t,n)-secret sharing scheme in which anyone, not only the participants of the scheme, can verify the correctness of the produced shares without interacting with the dealer and participants. The (t,n)-PVSS schemes have found a lot of applications in cryptography because they are suitable for<...

Designing Proof of Human-Work Puzzles for Cryptocurrency and Beyond

We introduce the novel notion of a Proof of Human-work (PoH) and present the first distributed consensus protocol from hard Artificial Intelligence problems. As the name suggests, a PoH is a proof that a human invested a moderate amount of effort to solve some challenge. A PoH puzzle should be moderately hard for a human to solve. However, a PoH puzzle must be hard for a computer to solve, incl...

A TorPath to TorCoin: Proof-of-Bandwidth Altcoins for Compensating Relays

The Tor network relies on volunteer relay operators for relay bandwidth, which may limit its growth and scaling potential. We propose an incentive scheme for Tor relying on two novel concepts. We introduce TorCoin, an “altcoin” that uses the Bitcoin protocol to reward relays for contributing bandwidth. Relays “mine” TorCoins, then sell them for cash on any existing altcoin exchange. To verify t...

Verifiable Encryption in Anonymous Ad Hoc Groups

In a verifiable encryption, an asymmetrically encrypted ciphertext can be publicly verified to be decypherable by a designated receiver without revealing the plaintext. In this paper, we introduce publicly verifiable encryption that is intended for a single anonymous decypherer within an ad hoc group of n receivers. The verifier can ascertain that the ciphertext can be decrypted by one receiver...
