Bitcoin 0.14 I want to try mining first genesis block, a new time, but don't know how to start testnet
used to create GenesisH0 https://github.com/lhartikk/GenesisH0

You need to change some code assertion values for your bitcoin testnet. the peershares wiki should give you a good place to start so you can see what you need to look for in the code for generating a genesis block. github.com/Peershares/Peershares/wiki/… – Fuzzybear Mar 13 '17 at 10:38

The old descriptions, it is out of date already – menfix Mar 13 '17 at 11:02

To mine the testnet genesis block you would use.
python genesis.py -z "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" -n 414098458 -t 1296688602
If you want to create a new genesis block run the following with your own time and leave out the nonce, you will be generated a new nonce.
python genesis.py -z "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" -t 1501755824
Here is what I get when running the above command, it will just take some time to find a block.
python genesis.py -z "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" -t 1501755824

To add your new genesis block to the Bitcoin testnet update the src/chainparams.cpp file, also delete any checkpointData entries on the testnet as those no longer apply to your new testnet chain.

This code crashes often when mining a genesis block that isn't the original bitcoin genesis block :( – Barney Chambers Nov 14 '17 at 8:33

What are you typing in exactly? If you paste it here I can help, I use GenesisH0 often to add RegTest and TestNet genesis blocks to coins that do not have them and once in a while a new MainNet block. – Peter Bushnell Nov 16 '17 at 15:18
