An encrypted Qtum Core wallet has a single passphrase that can be used to fully unlock the wallet, or unlock the wallet for staking only. To send coins or dump the private key the wallet must be fully unlocked.

To fully unlock the Qtum-Qt GUI wallet go to Settings - Unlock wallet and "untick" the little box "For staking only." Then enter the passphrase and click OK.

To fully unlock the qtumd daemon wallet using qtum-cli enter the command as appropriate for your operating system:


Here the wallet would be fully unlocked for 600 seconds.

You need to unlock the wallet before dumping the private keys.

The wallet.dat file can be used on any computer running the Qtum Core wallet. The private key can be used with any Qtum wallet that imports private keys.

Sorry I wasn't focused on the 32-bitness of your computer. Bitcoin discontinued 32-bit versions a few updates ago, as did Qtum. There are a few things to try.

For "Restore Wallet" with a version 0.19.1 installed, the full name for the 3rd option is "zapwallettxes=2 recover transactions without metadata" so that is the option to chose (with a v0.19.1 wallet installed on a 64-bit machine and a new blockchain fully synced).

If you are missing images maybe try another browser.

Another approach to recovering the wallet is using the private keys. On your 32-bit older version wallet, find the Console to check the active addresses with the "listaddressgroupings" command. For every address with a balance (may be only one) dump the private key using this command


Copy each private key (but be careful because private keys provide unencrypted access to your funds) and use to restore the wallet on Qtum Electrum (runs on 32-bit machines) or the Qtum Web Wallet (https://qtumeco.io/wallet). On the Web wallet this option is called "Restore from WIF".

Qtum had a manditory hard fork to Qtum Core wallet version 0.19.1 on August 28. This hard fork added offline staking protocol to mainnet.

Wallets that were not updated to version 0.19.1 by block 680,000 would show missing transactions, block reward problems, etc.

The recovery is basically 1) Update to version 0.19.1, 2) delete the local blockchain and resync the whole thing 3) run the zapwallettxes=2 command on startup. This blog gives more details for Windows wallets https://blog.qtum.org/hard-fork-special-windows-2c8febdbcd43

Use addnode with the command:


You can also try the addnode command with


If none of those are connecting, check your network connection with ping:

You can do a Google search for suggestions about using Electrum with VPNs, which is a common issue with Electrum. Or turn off your VPN when using it.

I’m guessing that countries that filter or restrict the Internet could also cause problems for Electrum. If you live in such a country, you probably know about this.

Decentralized permissionless blockchains would have less problems with VPNs and other restrictions. But think about the Electrum lite wallet architecture connecting to a server somewhere. If traffic to that server is restricted it may not work so well.

Hey Karto,

Linked below is a chart from 4Q 2019 showing Qtum uses. Besides these, some DApp/token projects pivoted or are still hibernating from the crypto winter. Probably the most active QRC20 token project currently is QC, a stable coin based on the Chinese Yuan https://www.quickcash.com/qc

Are you using a VPN? Electrum is sensitive to VPN settings and perhaps if there are national restrictions/filtering on the Internet. Some users report success using Tor with Electrum.

(I would send you a message if you allowed them from newbies)

onetwo12, design will be released this quarter with more details, but smart contract for delegation and online nodes providing staking with immediate payouts for each block reward.

@magisterr, Qtum offline staking will not be DPoS. It will be delegating offline wallet addresses and their UTXOs to online staking services nodes. Qtum already has one of the most decentralized networks and offline staking will add new PoS nodes to the network, increasing decentralization. That is different from DPoS, which may have two dozen validators/stakers, or less.

I've heard yes and soon (before the next full moon).

Qtum is open source, see https://github.com/qtumproject/qtum

Build like this https://github.com/qtumproject/qtum#building-qtum-core

@JanpriX, your footer is promoting YoBit but doesn't link to them?

Qtum working on an updated roadmap which will answer that question, to be linked here when it is published (date TBD). Confidential assets currently in research phase, such as https://eprint.iacr.org/2019/1435

This is operated by a stable coin company QuickCash from Singapore. Stable coins are backed by people depositing fiat currency. QuickCash has stable coins on Qtum and Ethereum.

The Qtum Core wallet application has three operating modes:

#1 a full node which makes peer-to-peer connections to the Qtum network, syncs the blockchain, and validates and relays all blocks and transactions

#2 a wallet which holds private keys and allows sending transactions and showing balances, and

#3 reaching proof-of-stake consensus as a block producer by staking coins.

The wallet can be operated in any of these modes: #1, #1 + #2, or #1 + #2 + #3.

Yes, operating a full node (#1) does not require coins, and in fact can participate in the Qtum Galaxy Full Nodes contest now.

Only the Qtum Core wallet, running as a node, wallet and proof of stake consensus (#1 + #2 + #3), can participate in staking.

The current block reward is 4.0 QTUM, plus a share of transaction fees and gas. I answered the annual ROI question previously, about 5%.

Hope this helps.
   

You can run a node with no coins. There is no minimum for staking, but would probably need several thousand to make it interesting. Wallets staking 100 coins, or less, have published blocks and won block rewards, but that is rare.

About 2 GB RAM and 10 GB disk. On AWS, t2.micro with a swap file Qtum AMI, on Google GCP g1-small Qtum-Core VM

This depends on Network Weight, the total number of coins being staked, and is typically in the 5 – 6% range. See the stake calculator for the current ROI and to try some different stake amounts.

The first halving will be in early December 2021, and the last block reward subsidy will be in 2045. Stakers (miners) also receive the transaction fees and Gas.
