Balanced Allocations and Double Hashing [PDF]
Proceedings of the 26th ACM symposium on Parallelism in algorithms and architectures, 2014 Double hashing has recently found more common usage in schemes that use multiple hash functions. In double hashing, for an item $x$, one generates two hash values $f(x)$ and $g(x)$, and then uses combinations $(f(x) +k g(x)) \bmod n$ for $k=0,1,2,...$ to

The Cost of Bitcoin Mining Has Never Really Increased [PDF]
Frontiers in Blockchain, 2020 The Bitcoin network is burning a large amount of energy for mining. In this paper, we estimate the lower bound for the global mining energy cost for a period of 10 years from 2010 to 2020, taking into account changes in energy costs, improvements in ...

More Analysis of Double Hashing for Balanced Allocations [PDF]
2016 Proceedings of the Thirteenth Workshop on Analytic Algorithmics and Combinatorics (ANALCO), 2015 With double hashing, for a key $x$, one generates two hash values $f(x)$ and $g(x)$, and then uses combinations $(f(x) +i g(x)) \bmod n$ for $i=0,1,2,...$ to generate multiple hash values in the range $[0,n-1]$ from the initial two.

Securing Financial Transactions with a Robust Algorithm: Preventing Double-Spending Attacks
Computers, 2023 A zero-confirmation transaction is a transaction that has not yet been confirmed on the blockchain and is not yet part of the blockchain. The network propagates zero-confirmation transactions quickly, but they are not secured against double-spending ...
