1. Which of the following is not a property of a cryptographic hash function? A) Deterministic B) Produces a fixed-size output C) Easy to reverse D) Collision-resistant 2. What is the primary purpose of using a cryptographic hash function in blockchain? A) To encrypt data B) To reduce...
35. What is a hash function? A hash function is a set of mathematical calculations performed on two blocks of data, with the primary input divided into two blocks of similar size. 36. What is the block size in a hash function? The block size depends on the algorithm used. 37. What a...

Experimental results validate that the system is effective in keeping data confidential, integrity, and accessibility so it is eligible for privacy-sensitive use cases. 展开 关键词: Privacy Data privacy Data integrity Employment Cryptographic hash function Blockchains Peer-to-peer computing Encryption ...
The hash function takes the message as input and produces a fixed size string, which is called as the hash value or message digest. This hash value is appended with the sending message to ensure message integrity. The main advantage is that, if there is any alteration in the message during...
There is https://github.com/riscv/riscv-crypto, which defines a lot of useful primitives that would accelerate typical blockchain operations with generic RISC-V code instead of custom host functions. I'm wondering if this is something th...
BLS is a digital signature scheme with aggregation properties that can be applied to signatures and public keys. For this reason, in the context of blockchains, BLS signatures are used for authenticating transactions, votes during consensus protocols, and to reduce bandwidth and storage requirements...
Fundamental Design of Blockchain – Hashchain Networks with a Decentralized Register Based on Cryptography MethodsThe general principles of construction of systems with the decentralized basis, at the heart of which cryptography methods are, are considered in the offered article, models of transactors ...
STARKs are a new form of zero-knowledge proofs for blockchains with a sophisticated architecture based on error correction codes, random queries, and inconsistency checks. The two main approaches to post-quantum cryptography are lattice-based cryptography and hash function-based cryptography. Lattice-...
