Compare SHA-256 vs Keccak-256 cryptographic hash functions, security, performance, and blockchain applications.

Proof-of-activity is a blockchain consensus that combines proof-of-work and proof-of-stake to enhance security and ...

⚠️ Warning: The Solidity implementation has NOT been audited. The purpose of building this Solidity implementation is to verify proofs for ZK-SNARK circuits which use gnark's mimc.

Abstract: This paper presents a detailed analysis of lightweight hash functions in the context of Internet of Things (IoT) security. With the proliferation of resource-constrained IoT devices, ...

Abstract: In real-world scenarios, the data usually appears in a streaming fashion. To achieve remarkable retrieval performance in such scenarios, online multi-modal hashing has drawn great research ...
