The hash/second units are small, so usually multiples are used, for large networks the preferred unit is terahash (1 trillion hashes), for example, in 2023 the Bitcoin hashrate was about 300,000,000 terahashes per second [1] (that is 300 exahashes or hash calculations every second).
Hash rate is the speed at which a cryptocurrency mining machine operates – it’s essentially a measure of the miner’s performance. Hash rate is usually measured in hashes per second, and the ...
MurmurHash is a non-cryptographic hash function suitable for general hash-based lookup. [1] [2] [3] It was created by Austin Appleby in 2008 [4] and, as of 8 January 2016, [5] is hosted on GitHub along with its test suite named SMHasher.
[6] [7] Included in Phoronix Test Suite. [8] Heaven Benchmark is claimed to be the first DirectX 11 benchmark. [9] [10] [11] It was officially introduced at the Windows 7 presentation on October 22, 2009.
The full attack vector of a piece is obtained as the union of each of the two unidirectional vectors indexed from the hash table. The number of entries in the hash table is modest, on the order of 8*2^8 or 2K bytes, but two hash function computations and two lookups per piece are required., [4] see the hashing scheme employed.

This design makes it easy to reuse Ascon in multiple ways (as a cipher, hash, or a MAC). [4] As of February 2023, the Ascon suite contained seven ciphers, [3] including: [5] Ascon-128 and Ascon-128a authenticated ciphers; Ascon-Hash cryptographic hash; Ascon-Xof extendable-output function; Ascon-80pq cipher with an "increased" 160-bit key.
The sponge construction for hash functions. P i are blocks of the input string, Z i are hashed output blocks.. In cryptography, a sponge function or sponge construction is any of a class of algorithms with finite internal state that take an input bit stream of any length and produce an output bit stream of any desired length.
