The official CryptoNote repository has been updated to include smart genesis block creation. Previously, it was required to comment and uncomment some parts of the source code. With our new currency creation flow, genesis block coinbase tx hash is created as follows:

1) Follow the forking guide and define all the parameters for your currency except for GENESIS_COINBASE_TX_HEX in /src/cryptonote_config.h. You should leave it blank:


2) Compile the binaries.

3) Start the daemon with the --print-genesis-tx argument:


The daemon will print out the genesis block coinbase transaction hash.

4) Insert the printed out tx hash to GENESIS_COINBASE_TX_HEX in src/cryptonote_config.h


5) Recompile the binaries. You are now ready to announce and launch your coin.
