HumanityLink is a decentralized commonwealth database system with a total target of 8 Billion coins to be issued by 2025. An MySQL database will be connected to the blockchain and document the evolution of human population and accomplishments. Users hold the keys to their own coins and transact directly with the help of a P2P POW and Future POS network to check for double-spending.


-Name: HumanityLink

-Unit: HUM

-Algorithm: SHA-256

-Proof: POW / POS-2022

-Total Coins: 8,000,000,000 //Human Population Estimate by 2025

-POS Activation: Block 2600

-POS Reward: 84% Annual - 7% Monthly

-POS Minimum Stake Age: 120 Blocks - //2 Hours

-Pos Maximum Stake Age: Unlimited

-Transaction Network Speed: ~1 Second

-Transaction Network Confirmation: ~30 Seconds

-Transaction Maturity: 6 Blocks

-Mining Coinbase Maturity: 60 Blocks

-Small Blockchain with quick install & sync

  • 2 x 1gb/s nodes & 4 x 100mb/s node always online
  • A usb SHA-256 miner at 20Gh/s always moving the blockchain even in case of 0 pool hashrate.


-Premine of 0.625% at block 1 (see code below) + first ~500 blocks to start up the blockchain, connect and sync all the hard nodes worldwide, setup security checkpoints, synchronize explorer and connect the mining pool.

-All coins will be used for the faucet, and exchanges fund. The faucet will be reloaded with 5000 coins per day for 2000 days / total 10 Million Coins from block 1.

-The HumanityLink database will document the evolution of human population by tracking and storing the progress of humanity. The amount of total coins in circulation by 2025 will be the same as the number of humans alive and each coin will represent a single human. Important events will have their own timestamp and will be indexed in a searchable database for future documentation and research.

-When the POW is completed (Aprx. 10 Years) the POS will switch down to ~1.85% annually to maintain the increase in population on par with the international standards on humanity statistics(see formula below).

-Why SHA-256 in 2018? A database system benefits from high hashrate for optimal stability and SHA-256 asics can provide the highest IOPS than any other algorithm currently. With the abundance of older asic hardware; USB miners, blockerupters, or earlier antminer models, the blockchain can have enough hashrate to be stable and also give a purpose to older and currently unprofitable devices per btc/bch difficulty.

How will the POS rate be calculated to maintain even distribution:

dN -- = aN - (bN^2) dt

N=population size

a*N=birth rate

b-n^2=death rate

*No translations needed at the time(thank you for you interest).

-The linux wallet is the most up to date wallet with often code and graphic updates. To use the latest wallet install it from the github source on a linux Os. Follow the installation guide for ubuntu below, it should be only copy paste even for beginners. For any problems leave a comment on this thread with your error.

-If you are making an explorer or a pool and you are trying to get the network hashrate the command gethashrate doesn't work with this version of the wallet yet so it's not your website that's not syncing.

-The last nodes will be going live right now and should be online during the announcement. Currently there are 2 hard nodes with 1gb/s connection, 1 in Seoul and 1 in Seattle. There are 4 hard nodes with 100mb/s connection, Oslo, Jakarta, Montreal and Sao Paolo. We are planning on adding 1 more 1gb/s node in Europe and 5 more 100mb/s nodes worldwide.

-Nodes are hardcoded already, and the newest nodes will be listed and added in the list below.

The name of the configuration file is: humanitylink.conf




-We recommend adding at least 3 nodes for faster wallet synchronization. You can either open the debug console and add each one as a command. For example write: addnode= press Enter, addnode= press Enter, etc.

Or by creating a file named humanitylink.conf, pasting the above nodes as is including the addnode= in the front of each IP. And place that file in C:/users/YOURUSERNAME/AppData/Roaming/humanitylink. Usually AppData is hidden so enable hidden files to find it. Also make sure your conf file is not saved as a .txt file.

-Installation guide for ubuntu:

// paste following in Terminal

sudo apt-get update

sudo apt-get install git curl tar unzip software-properties-common -y

sudo add-apt-repository ppa:bitcoin/bitcoin

sudo apt-get update

sudo apt-get install build-essential libssl-dev libdb-dev libdb++-dev libboost-all-dev -y

sudo apt-get install libdb-dev libdb++-dev libboost-all-dev libminiupnpc-dev libminiupnpc-dev -y

git clone

cd humanitylink/src/leveldb

chmod 775 build_detect_platform

sudo make libleveldb.a libmemenv.a

mkdir -p obj/zerocoin

sudo chmod -R 777 ~/humanitylink/

cd humanitylink/src

mkdir obj

make -f makefile.unix USE_UPNP=1

sudo chmod -R 777 ~/humanitylink/

cd /humanitylink


sudo chmod -R 777 ~/humanitylink/


//For vps with less than 1Gb RAM use this make command instead;

make -f makefile.unix USE_UPNP=1 CXXFLAGS="--param ggc-min-expand=1 --param ggc-min-heapsize=32768"

Block reward and premine code of 0.625%:

int64 GetBlockValue(int nHeight, int64 nFees) { int64 nSubsidy = 10000 * COIN; if(nBestHeight == 0) { nSubsidy = 62331429 * COIN; }

if (fDebug && GetBoolArg("-printcreation"))
    printf("GetProofOfWorkReward() : create=%s nSubsidy=%"PRId64"\n", FormatMoney(nSubsidy).c_str(), nSubsidy);

return nSubsidy + nFees;


// miner's coin stake reward based on coin age spent (coin-days) int64_t GetProofOfStakeReward(int64_t nCoinAge, int64_t nFees) { int64_t nSubsidy = nCoinAge * COIN_YEAR_REWARD * 33 / (365 * 33 + 8); static const int64 nTargetTimespan = 4 * 60; static const int64 nTargetSpacing = 2 * 60;

Versions used in this release:

  • GCC 4.3.3
  • OpenSSL 1.0.1f
  • Berkeley DB 4.8.30.NC
  • Boost 1.37
  • miniupnpc 1.6


[Note:] Use command sudo chmod -R 777 -/humanitylink/ before [make -f makafile.unix] and before [sudo qmake] and before [sudo make] command. Run sudo chmod -R 777 -/humanitylink/ , every time before each installation command.

You need the Qt4 run-time libraries to run HumanityLink-Qt. On Debian or Ubuntu:

sudo apt-get install libqtgui4

Unpack the files into a directory and run:

  • bin/32/humanitylink-qt (GUI, 32-bit)
  • bin/32/humanitylinkd (headless, 32-bit)
  • bin/64/humanitylink-qt (GUI, 64-bit)
  • bin/64/humanitylinkd (headless, 64-bit)


Unpack the files into a directory and run humanitylink-qt.exe.
