Please, post to github if you find any issues. But, please, don't discuss the block size issue itself in this post or the PR, the size is simply -blocksize. I repeat the text here: It would be generally good to have more people collecting data and conduction simulations related to different consensus maximum block sizes. This PR attempts to simplify that work. Even if it may take long until it is merged (because it requires many little steps to be taken first), this branch (or a fork of it) can be used right now for testing purposes. One can use it, for example, like this: ```./src/qt/bitcoin-qt -chain=sizetest -debug -printtoconsole -gen=1 -genproclimit=20 -blocksize=2000000``` I will rebase and update the list of dependencies accordingly as things get merged. Dependencies: - Chainparams: Translations: DRY: options and error strings #6235 - CTestNetParams and CRegTestParams extend directly from CChainParams #6381
