NYE is a digital peer to peer network with POW/POS and Masterndoe. It is a fork of PIVX.

Main Use: As a POS - Masternode cryptocurrency. 

What we cloned: Available code of NYE (It's derived from https://github.com/PIVX-Project/PIVX/tree/v2.3.1)

Operating System: Ubuntu 16.04.6 LTS x64

Processor: Intel(R) Core(TM) i5-3570 CPU @ 3.40GHz

Memory: 7.6 GiB

Step 1. Cloning the NYE/PIVX to the local machine (we can also fork it to our repository first, and then clone).

--------------------------------------------------------------------------------------------------------------------------------------------

Step 2. Changing Names in files:

find ./ -type f -readable -writable -exec sed -i "s/NYECOIN/YUCOIN/g" {} \;
find ./ -type f -readable -writable -exec sed -i "s/nyecoin/yucoin/g" {} \;
find ./ -type f -readable -writable -exec sed -i "s/NYE/YUC/g" {} \;

--------------------------------------------------------------------------------------------------------------------------------------------

Step 3. Renaming files:

find . -exec rename 's/nyecoin/yucoin/' {} ";"

Note: Renaming files is also an important part as not doing so will cause erros during compilation.

After Doing step 2 and 3, make a test compilation and fix issues if any.

--------------------------------------------------------------------------------------------------------------------------------------------

Step 4. Alert and SporkKey

We will need to place new alert keys (put public keys in cod and keep prviate keys safe)

Generate Key-Pairs:

openssl ecparam -genkey -name secp256k1 -out alertkey.pem
openssl ec -in alertkey.pem -text > alertkey.hex
openssl ecparam -genkey -name secp256k1 -out testnetalert.pem
openssl ec -in testnetalert.pem -text > testnetalert.hex
openssl ecparam -genkey -name secp256k1 -out genesiscoinbase.pem
openssl ec -in genesiscoinbase.pem -text > genesiscoinbase.hex
openssl ecparam -genkey -name secp256k1 -out strSporkKey.pem
openssl ec -in strSporkKey.pem -text > strSporkKey.hex
openssl ecparam -genkey -name secp256k1 -out teststrSporkKey.pem
openssl ec -in teststrSporkKey.pem -text > teststrSporkKey.hex

Read Public Keys:

cat genesiscoinbase.hex
cat testnetalert.hex
cat alertkey.hex
cat strSporkKey.hex
cat teststrSporkKey.hex

Finally Place them at their respective places, and we are good to go.

--------------------------------------------------------------------------------------------------------------------------------------------

Step 5. Genesis Blocks:

We will have to figure out three genesis blocks. One for Mainet, one for Testnet and one for Regtestnet. 

i) Change the public key associated with All Genesis Block (both Mainnet and Testnet)
ii) Change the Timestamp and Epoch Time for Genesis Blocks (All three, try to keep constant difference with them)
iii) Change all Alert keys for both Mainnet, Testnet and Regtestnet (5 keys, 3 vAlertPubKey and 2 strSporkKey)
iv) Then finally copy and paste the code which is used to find the Genesis Block.
iv) Run the all the daemons one by one to get the correct Genesis Block Hash, Merkel Hash and Nonce.

CODE: 

NOTE: Place this code just before the method call: hashGenesisBlock = genesis.GetHash(); in file chainparams.cpp for all the three networks.

/*
        if(genesis.GetHash() != uint256("0x"))
        {
              printf("MSearching for genesis block...\n");
              uint256 hashTarget;
              hashTarget.SetCompact(genesis.nBits);
              while(uint256(genesis.GetHash()) > uint256(hashTarget))
              {
                  ++genesis.nNonce;
                  if (genesis.nNonce == 0)
                  {
                      printf("Mainnet NONCE WRAPPED, incrementing time");
                      std::cout << std::string("Mainnet NONCE WRAPPED, incrementing time:\n");
                      ++genesis.nTime;
                  }
                  if (genesis.nNonce % 10000 == 0)
                  {
                      printf("Mainnet: nonce %08u: hash = %s \n", genesis.nNonce, genesis.GetHash().ToString().c_str());
                  }
              }
              printf("Mainnet block.nTime = %u \n", genesis.nTime);
              printf("Mainnet block.nNonce = %u \n", genesis.nNonce);
              printf("Mainnet block.hashMerkleRoot: %s\n", genesis.hashMerkleRoot.ToString().c_str());
              printf("Mainnet block.GetHash = %s\n", genesis.GetHash().ToString().c_str());
        }
*/

--------------------------------------------------------------------------------------------------------------------------------------------

Step 5. Now change all the other important things in chainparams.cpp like:
* the Pointer to Character Message bits, 
* All kind of address identifiers: base58Prefixes[PUBKEY_ADDRESS] , base58Prefixes[SCRIPT_ADDRESS], base58Prefixes[SECRET_KEY],  base58Prefixes[EXT_PUBLIC_KEY], base58Prefixes[EXT_SECRET_KEY].
* P2P Port (chainprams.cpp) and RPC Port (chainparamsbase.cpp)
* Also mention last Proof of Work block(after it chain will switch to POS):
nLastPOWBlock = 500;

* strMasternodePoolDummyAddress

--------------------------------------------------------------------------------------------------------------------------------------------

Step 6. Once everything is done in chainparams.cpp, We need to fix the rewards in main.cpp
