I did a Monero fork and i added to it a code to generate for me a new genesis tx with the knowed command
--print-genesis-tx and it works great at start, it generates something like this
013c01ff000180cab5ee01029b2e4c0281c0b02e7c53291a94d1d0cbff8883f8024f5142ee494ffbbd08807121015b6c9c53d57e60a1283edfba1d2a6510c922f351d86c7f537de64082fdb76110 but if a try to do a solo mining i get this:
2017-07-23 16:27:52.542 [miner 0] ERROR cn src/cryptonote_core/cryptonote_core.cpp:917 mined block failed verification
2017-07-23 16:27:52.561 [miner 0] INFO global src/cryptonote_basic/miner.cpp:456 Found block for difficulty: 1
2017-07-23 16:27:52.561 [miner 0] ERROR verify src/cryptonote_core/blockchain.cpp:3164 Block with id is INVALID: <b89cd1e533c067989f52f3dc38f3b14fed297f3b20a2c9a0910e31bcdb9e4092>
I want to premine my own cryptocurrency so the first block is 0 and the next is the max amount. But i think it isn't the problem, I think the problem is the genesis that i create.
