Why has it been re-launched? The first block of this re-launch was on the last day of June. What happened to the old block chain?
the old block chain had a lot of faults, all users' coins are being changed 1: 1 by the new chain.
This new chain is faster and safer and more versatile thanks to masternodes.
in addition, the premine of 5200000000 has been reduced by only 17000000 and now the max supply is unlimited. also the reward is limited to 1 NPC per block.
Also the blocks are faster, 60 seconds, and we have the possibility of instansend.
Now there is also the possibility and compatibility with other platforms and applications.
Above all, the improvements in the code and security.
