2022-08-23Add function to validate difficulty changesSuhas Daftuar
The rule against difficulty adjustments changing by more than a factor of 4 can be helpful for anti-DoS measures in contexts where we lack a full headers chain, so expose this functionality separately and in the narrow case where we only know the height, new value, and old value. Includes fuzz test by Martin Zumsande.

Requiring arith_uint256 at such a base level is not good for modularity.

Not used, and REGTEST already allows creating blocks at the lowerst possible difficulty.
2015-02-21Add unit tests for next difficulty calculationsRoss Nicoll
Split GetNextWorkRequired() into two functions to allow the difficulty calculations to be tested without requiring a full blockchain. Add unit tests to cover basic difficulty calculation, plus each of the min/max actual time, and maximum difficulty target conditions.

2014-08-26Split up util.cpp/hWladimir J. van der Laan
Split up util.cpp/h into: - string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach) - money utilities (parsesmoney, formatmoney) - time utilities (gettime*, sleep, format date): - and the rest (logging, argument parsing, config file parsing) The latter is basically the environment and OS handling, and is stripped of all utility functions, so we may want to rename it to something else than util.cpp/h for clarity (Matt suggested osinterface). Breaks dependency of sha256.cpp on all the things pulled in by util.
