Htmlcoin Staking Tutorial

Htmlcoin employs PoS (Proof of Stake) consensus mechanism, which is different from Htmlcoin PoW (Proof of Work). The mining process in PoS system is called staking. The block producer will get 1,250 HTML, as well as the transaction fees and gases as block reward. So the real reward is usually more than 1,250 HTML in total.

Basic requirements for staking:

  1. Run a Htmlcoin fullnode, and keep online (Since Htmlcoin is using PoS, we don't need any mining machine, just PC or even Raspberry Pi can run a fullnode);

  2. Have some HTML in the wallet (fullnode)(Any amount of HTML can be used for staking, more HTML means higher possibility to stake).

If you have no HTML yet, please get some from market before you doing following staking settings.

Currently, Htmlcoin Core wallet is the only wallet that support Htmlcoin PoS staking. Note that other wallets like mobile wallet and Htmlcoin Electrum are not able to stake for the time being.

Two ways to stake:

  • Method 1:Staking with htmlcoind, using command line, suitable for Linux/OSX/Windows/Raspberry Pi users who are familiar with command line tools.

  • Method 2:Staking with htmlcoin-qt wallet, with GUI, suitable for common users.

Either way works in the same way for staking, so you can choose either method you like.

Method 1:Staking with htmlcoind (command line)

1. Run htmlcoind

To run htmlcoind, please refer to"How to deploy Htmlcoin node".

Follow the guidance to run htmlcoind:

./htmlcoind -daemon

Staking is default on for htmlcoind, so no need for other options if you only want to stake.

2. Send some HTMCOIN to your wallet

First you can generate a new address with:

./htmlcoin-cli getnewaddress

This will generate a new address with Prefix 'H'. You can send some HTML to this new generated address for staking. You can generate as many addresses as you like, and send arbitrary HTML as you like for staking.

Note:The coin should wait for 500 blocks before being able to stake, i.e. about 17 hours to MATURE..

After the Htmlcoin node syncing to the latest block, you can check current balance with ./htmlcoin-cli getbalance or get utxo list with./htmlcoin-cli listunspent。(what is UTXO?)。

Please do following steps after your coin is mature.

3. Check staking info

Check current staking info with:

./htmlcoin-cli getstakinginfo

You might get the result like this:


"enabled": true,

"staking": true,

"errors": "",

"currentblocksize": 1000,

"currentblocktx": 0,

"pooledtx": 5,

"difficulty": 5683612.564280176,

"search-interval": 46,

"weight": 53206430,

"netstakeweight": 2278172497819029,

"expectedtime": 5480654870


enabled means if your wallet have enabled staking, it should be true by default. staking means if your wallet is currently staking (mining). weight stands for the amount of HTML that is staking right now, with unit 10^-8 HTML, here in the example, we have 0.532 HTML staking. expectedtime stands for the expected time that you will get a reward, the unit is second.

4. How to stake if the wallet is encrypted?

If your wallet is not encrypted, you can skip this section. However, for security, we recommand you encrypt your wallet. (How to encrypt?)

Htmlcon wallet can be encrypted with encryptwallet. However, staking will be stopped when it is encrypted. For example, ./htmlcoin-cli getstakinginfo for a encrypted wallet:


"enabled": true,

"staking": false,

"errors": "",

"currentblocksize": 1000,

"currentblocktx": 0,

"pooledtx": 94,

"difficulty": 5788429.670171153,

"search-interval": 0,

"weight": 53206430,

"netstakeweight": 2438496688951881,

"expectedtime": 0


See staking turns to false, which means wallet is not staking.

You can use walletpassphrase to unlock wallet for staking:

./htmlcoin-cli walletpassphrase "<your passphrase>" 99999999 true

The meaning of the arguments can be found in the documents "How to encrypt?".

After unlocking, you can double check getstakinginfo, it should look the same with previous unlocked result, staking become true.

Method 2: Staking with htmlcoin-qt wallet (official PC wallet)

How to use Qtum-qt tutorial? please refer to Htmlcoin qt wallet tutorial. Current supported platform: Mac/Linux/Windows.

1. Open Htmlcoin qt wallet

Launch the wallet.

2. Send some HTML to your wallet

If you already have some HTML in your wallet, you might skip this step.

If not, please send some HTML to your wallet first. (How to receive?).

Note:The coin should wait for 500 blocks before being able to stake, i.e. about 17 hours to MATURE..

3. Check staking status

The flash sign at the bottom of wallet shows staking info :

Solid black flash means it is staking now. For more information, you can put your mouse on the flash, e.g.:

  • Staking: if it is staking;

  • Your weight is: How many HTML are able to used for staking, unit is HTML;

  • Network weight is: How many HTML are staking in the network, unit is HTML

  • Expected time: expected time to get reward, unit is Day.

Hollow flash measn it is not staking

Possible reasons for not staking:

  • 1.There is no coins of no mature coins (more than 500 confirmations(blocks)) -- Solution: send some HTML to the wallet and wait for 500 blocks (about 17 hours);

  • 2.Wallet is locked/encrypted -- Solution: unlock the wallet for staking. (How to unlock?)

No flash sign means staking is disabled

About block reward

The block producer will get more than 1,250 HTML rewards, something to keep in mind:

  • The reward come from a new transaction, you can check balance to see if you get the reward.

  • HTML will be sent to you after 500 blocks.

  • The staked coins (UTXO) will be locked for 500 blocks, during this period, it cannot be spent nor be used to stake.

How to disable staking?

Staking is by default enabled for Htmlcoin wallet. If you need to disable staking for some reason (for example exchanges are always recommanded to disable staking), you might following anyone of the 3 ways below:

1) Add -staking=false when running Htmlcoin node:

./htmlcoind -staking=false -daemon

For qt wallet, it is like:

./htmlcoin-qt -staking=false

2) Add config staking=false in htmlcoin.conf;(How to set htmlcoin.conf?)

3) Encrypt wallet, since encrypted wallet will automatically stop staking.(How to unlock?)
