[ANN] (QTUM) - A Scalable Smart Contract Platform w/ Proof of Stake

[efemtekem]

I have a question, friends say, delete the local copy of the blockchain, after installing the new version ..... Are they talking about deleting the Blocks "," stateQtum "," database "folders and" banlist.dat "files in the AppData / Roaming / Qtum file, or another step I was unable to update before the hard fork. Due to this incident I am trying to upload my wallet.dat file before the hard Fork to the Qtum wallet version 0.19.1 so I wanted to get some ideas to avoid doing anything wrong.

My last question is I can't see the "deleteblockchaindata -delete the local copy ......" tab in the Restore Wallet option. What can I do so that I can see that option.

You Missed the Hard Fork – Now What?

Qtum mainnet hard forked on August 28 to launch offline staking protocol. Qtum Core wallet version 0.19.1 was a mandatory update for protocol and consensus changes and implemented a hard fork at block 680,000, which means older version wallets are incompatible and were automatically disconnected from mainnet.

If your wallet missed the hard fork it would be disconnected from mainnet, but still able to peer with other wallets that missed the hard fork, making up a smaller dying “split chain”. There are two fundamental reasons to not be on the split chain: missing transactions and lost block rewards.

Hard Fork Special: Mac

In this blog, we look at the Qtum mainnet hard fork at block 680,000 on August 28, 2020. This hard fork added protocol and consensus changes to activate offline staking and was a mandatory update for the Qtum Core wallets Qtum-Qt (the GUI desktop wallet) and qtumd (the command-line server wallet). There were no updates required for other types of wallets (mobile wallets, hardware wallets, etc.) and no new coins were created.

The hard fork for Qtum version 0.19.1 added offline staking capability, allowing address delegation and super stakers. The Qtum Core wallet can now be operated as a super staker to receive address delegations from others and stake their UTXOs. The hard fork happened at block 680,000 on August 28, 2020, at 7:11 pm GMT and only applied to the Qtum Core wallets Qtum-Qt and qtumd, no other wallets. While updated wallets made the hard fork automatically, users that don’t update in time saw their wallets disconnected from the main network, are not be able to make transactions, and (for staking wallets) may see their coins staked on a split chain, where they are difficult to recover. There is no new coin from the hard fork, but a good chance to temporarily lose coins for staking wallets that did not update in time.

sorry but for me as an Italian it is difficult to understand !!
I have the wallet v.0.19.1 .. do I have to resynchronize or update the wallet ?!
where are these addresses to have the offline stake or the delegation of addresses?
please do something more user friendly

A few questions...

Is this a new wallet?

If this is a new wallet with zero balance then you do not need to do anything except make sure that you have properly backed your wallet up. More details for of securing your wallet can be found here docs.qtum.org

If it is not a new wallet and you updated the wallet to v.0.19.1 after October 28th, then please read this article https://blog.qtum.org/you-missed-the-hard-fork-now-what-996bab6639de

Thanks for all the info.
I have a new wallet with the funds on it.
I ran into issues with offline stake in testnet but now it's been easier for me.
Now I already have all my coins delegated for offline stake.
Thanks a lot again.

One of the few ICO projects developed well.
You can see that I am a really well-made team. They deserve to be in the top 3.
Thanks for your hard work.

most of ICO dead after they raise money.

That's because this ICO was secretly a premine so they just sold the free coins they got on the investors heads and continue to do so. Most ICOs are like this, they just say they funded X but really just gave themselves the coins, partner with exchanges, wash trade and sell on investors. Thats why the price never really goes up because logically there is no reason for it to keep hitting new lows unless someone got a free ride. Similar to how a thief will sell BTC at any price (why should they care, they didn't pay for it) so does ICO fraud do similar things. Even with development, from an investment standpoint I would never recommend anyone gets behind someone who has no problem backstabbing their own investors.

Just sayin...

What does it means  “offline staking”? And which type of DEFI do u have? In fact Staking is not a DEFI in that sense which market means nowdays. Do u have lending, borrowing, farming etc.?

Qtum Updates for September

The month of September continued with Qtum’s Stake-A-Thon and the Qtum DeFi Grant Program! If you haven’t heard about the DeFi grant program, Qtum has put up to 5 million dollars for the development of DeFi projects on the Qtum blockchain, and we’ve received a nice array of applications already. So, why is Qtum a great choice for DeFi?

Qtum users can enjoy the benefits of high TPS and low transaction fees. Qtum blockchain also offers more scalability by having the capability of changing parameters of the blockchain without the need for a hard fork. If you have an awesome development team, or you’re a one-person show that wants to build something transformative, check out the link below and bring your best DeFi solution to Qtum.

Delegating Addresses in Qtum: FAQs

After a month of the testnet Stake-A-Thon and a month of the mainnet Stake-A-Thon we got a lot of community questions about the details of delegating addresses for offline staking, picking a super staker, splitting UTXOs, etc.

Qtum Improvement Proposal # 26 Reduce Block Spacing

This Qtum Improvement Proposal (QIP) describes changes in blockchain parameters and logic to reduce target block spacing (the average spacing between blocks).

From launch, Qtum has used a target block spacing (a configuration parameter) of 128 seconds. Target and difficulty are adjusted for every block to maintain the average 128 seconds block spacing, with considerable variance due to the randomness needed for decentralized consensus.

This proposal would change parameters and perhaps other logic, to reduce the average block spacing to 16 seconds if there are good results after testing/tuning, or perhaps 32 seconds. The consensus algorithm currently evaluates every UTXO at 16-second intervals, targeting a solution (publishing a block) after 8 intervals, or 128 seconds. A block could be published after the first interval (in 16 seconds) or occasionally, long after the target of 8 intervals.

New block headers and new blocks can be proposed continuously on the network, but consensus logic validates with a 16-second granularity, meaning blocks are validated and time-stamped with 16-second granularity according to the interval spacing.

You can read more about it here: https://github.com/qtumproject/qips/issues/26
