Qtum — CoinDCX AMA was held on July, 10 2020. John Scianna and Jackson Belove answered questions from the CoinDCX group and the group. If you happen to missed the AMA, it’s okay we’ve got a re-cap of it proper right here.
The AMA began out with temporary introductions from Qtum’s Head of Development, John Scianna, and from Qtum’s lead researcher, Jackson Belove.
John Scianna: I’m John Scianna, and I’m the Head of Development at Qtum. I assist out with our group, advertising, and partnerships to verify the Qtum ecosystem continues to increase. One in every of my missions is to see Qtum develop into simpler to make use of and to make utilizing it extra enjoyable. I’ve been with the group since August 2016, so it’s been a journey of just about 4 years and it’s superb to see how a lot Qtum has grown since I began.
That is certainly one of my favourite photos, I consider it’s from October 2016 once we have been all in Shanghai. All of the individuals within the image are nonetheless with the group.
Jackson Belove: I’m a researcher and tech blogger for Qtum, and I take pleasure in doing quite a lot of tech help on our social channels. I’ve a technical background and my important position is explaining the know-how, use the wallets, and stuff like that. So not solely did I fall down the proverbial crypto rabbit gap, I’m making an attempt to dig it deeper for everybody else to fall down. I’ve been with Qtum a couple of yr now, and previous to that was an energetic group member.
I’m keen on figuring out how Qtum began and the journey up to now. I’m certain there’s an excellent story there.
John Scianna: Our CEO and Co-founder Patrick Dai got here up with the thought of including good contracts to the bitcoin blockchain. Patrick needed to take some great benefits of bitcoin, particularly the sturdy testing/safety of the blockchain and UTXO mannequin, and mix it with the good contract capabilities of Qtum. On the time, Patrick and some different group members have been engaged on Vechain and so they observed that engaged on Ethereum was fairly tedious, in order that they figured there needed to be a greater approach and thus Qtum was born.
Trying again, it looks like that was the simple half. After we launched in 2017, issues actually began heating up past most individuals’s creativeness, then there was the China ICO ban, and lots of different ups and downs, it was an actual journey. Nonetheless, we continued to remain targeted on the know-how though we withdrew a bit from the highlight.
Lots has occurred since these days, and because the market matured, we might see our imaginative and prescient was coming extra in-line with actuality. That’s why we’re constructing protocols like Offline Staking, Phantom, and x86.
2017 was an actual roller-coaster and now that we’re right here, what are a few of the tasks you’re most enthusiastic about over the upcoming yr?
Jackson Belove: I’m most enthusiastic about offline staking, which is operating on our testnet now and can come to mainnet on the finish of August. Qtum blockchain is Proof of Stake, however so far individuals needed to run a full node for staking. Proof of Stake consensus and the entire mechanism of choosing and validating the block writer has been a analysis curiosity of mine from the start. With offline staking we increase that so extra individuals can take part in staking to safe the community, and win block rewards!
We now have two different huge tasks on our roadmap: Phantom privateness protocol, which can permit personal property and personal transactions, and Neutron/x86 digital machine, which will probably be a brand new good contract platform for Qtum, along with the EVM we’ve got now.
In what methods can individuals within the blockchain and crypto group become involved in your applications?
John Scianna: First off, we’re launching a Testnet Stake-A-Thon subsequent week. This can give everybody the prospect to check out our new staking implementation, at no cost, and get an opportunity to win some rewards for serving to us take a look at out the protocol. This will provide you with a head begin on what it’s wish to run a Tremendous Staker and to see how straightforward it’s to delegate your tokens to a web-based node.
Operating a node/Tremendous Staker (after August 28th) will probably be one of the tangible methods to be a part of the Qtum group and ecosystem. You’ll have the facility to validate transactions and blocks from your home, or from the cloud. There’s solely a handful of blockchains the place a median consumer can nonetheless do that right now, and Qtum is certainly one of them. I extremely advocate the Stake-A-Thon. There are different methods comparable to making contributions to our github and writing documentation.
Jackson Belove: I’m an enormous Testnet fan boy, if anybody wants assist getting up on Testnet.
Good! Are there any hyperlinks the place we individuals want to go to to take part on the Stake-A-Thon? The Qtum webpage?
John Scianna: Yeah, we will certainly have a hyperlink for signup there at https://qtum.org when the Stake-A-Thon launches, and put it on Twitter, and so forth.
Jackson Belove: Here’s a weblog some man wrote about Testnet, to assist prepare for the Stake-A-Thon:

What’s the position of Qtum’s Phantom protocol? Why does Qtum’s Phantom protocol use zk-SNARKs Based mostly on Good Contracts?
John Scianna: Phantom is one my favourite privateness protocol, so I’ll reply this. Qtum selected to make use of zk-SNARKs as a result of it’s extra mature and environment friendly. Zero Data proofs have been researched for over 20 years, it’s simply now they’re being carried out into blockchain know-how. Qtum needed privateness on the good contract layer to make it attainable for anybody to create personal & untraceable property for decentralized functions, like digital property, steady cash, and funds on the Qtum blockchain. Our purpose is that Phantom will develop into a standardized privateness protocol used throughout blockchains. We see privateness as the long run, and we need to make it possible for everybody has entry & the flexibility to create their very own personal property.
Jackson Belove: Phantom are good contracts that basically know hold a secret!
I do know that the Neutron is being accomplished, when will the Neutron be formally used? How will the Neutron result in adjustments in Qtum’s ecosystem and actions?
Qtum Neutron is at the moment in growth. Will probably be out there to be used after it’s accomplished and audited.
(sorry to get extra technical right here) Neutron is a middleware for our blockchain stack that sits between the gory particulars of the blockchain (UTXOs, transactions, networking) and the higher good contract layers. Will probably be usable throughout various kinds of blockchains, however beginning with Qtum’s UTXO-based blockchain. Proper now there are quite a lot of totally different platforms (ie, EOS, NEO, and so forth) however every with their very own particular methods of constructing a wise contract and what a wise contract appears like. Neutron will make this extra constant and make it to be able to reuse contract code simpler.
Another cool issues about Neutron is that good contracts will use Rust (a memory-safe language) and introduce the idea of “lease” for storage, so that you don’t get horrible blockchain bloat. No person likes a bloated blockchain.
How does the QTUM deal with the problems about safety, scalability, and information privateness?
John Scianna: Safety is crucial facet of a blockchain, with out it, a blockchain doesn’t stay as much as its full potential. This is the reason we selected the UTXO mannequin for our underlying blockchain. The builders behind Bitcoin & the UTXO have put numerous hours into ensuring the code is safe, and whereas doing it they’ve even discovered bugs in different non-blockchain software program.
By way of scalability, since Qtum is a mix of Bitcoin & Ethereum, Qtum can take scalability enhancements from each. We now have been doing our personal analysis and implementation of the lightning community and we additionally pay shut consideration to layer-2 good contracts on ethereum.
With regard to information privateness, this one purpose we’re focusing quite a lot of our assets on the Phantom Protocol. We consider that the core blockchain must be clear, as a result of it permits for the general public to audit the blockchain which is tremendously helpful for some functions, however for others it’s extraordinarily detrimental to what’s making an attempt to be achieved. The Phantom Protocol permits for the customers who want privateness to have it, with out taking away the transparency facet from customers that want that.
Each business is severely affected by the egregious state of affairs of the Covid-19 outbreak. Does it have an effect on the expansion of #QTUM and its? What are your plans to show challenges into alternatives for #QTUM growth?
Jackson Belove: Good query and we hope everyone seems to be staying secure. There was minimal impression from this as a result of Qtum has a distributed group (Asia, Europe, Africa, the Americas) and we are able to simply earn a living from home. If there is a chance from a pandemic it’s simply to maintain engaged on the undertaking, with much less time misplaced to commuting, haha. We have been discussing and planning opening an workplace in Denver as of February and hiring some native builders and mainly to unite the Neutron and US individuals on the whole, however then covid occurred so we’re not opening an workplace till all of that’s over, hopefully fall of this yr. In any other case although we’re all accustomed to working from house, and the one downside is our canine barking through the firm calls.
QTUM is appropriate with BTC & ETH Blockchain whereas each are QTUM opponents, Why do you select to make each appropriate with QTUM?
John Scianna: Qtum is appropriate with Bitcoin and Ethereum as a result of it could actually implement good contracts from Ethereum whereas adopting the extremely safe UTXO mannequin utilized in Bitcoin. We made these know-how choices as a result of we didn’t need to reinvent the wheel.
This method is an environment friendly solution to make enhancements on each protocols with out having these blockchains change their core code. For bitcoin, something that requires a fork, is sort of undoubtedly not going to get authorized, so it’s exhausting to advance the know-how there, and with ethereum, the place quite a lot of growth is on the applying layer, builders can simply port their code to Qtum since we use the EVM like ethereum, and their app ought to work fantastic with solely minor adjustments.
In a way, it’s a win for everybody. Each group will get their code reviewed extra, builders don’t should hold rebuilding issues, and we get to check out new options that simply would possibly change the world
I’ve been studying in regards to the decentralized governance protocol (DGP) utilized by Qtum. What are the advantages of DGP for Qtum?
Jackson Belove: DGP is a approach for Qtum to make on-chain adjustments (with no exhausting fork) in necessary blockchain parameters like block measurement and fuel pricing (for good contracts). Block measurement in adjustments particularly led do horrible schisms on bitcoin. Qtum block measurement now could be 2 MB, however can simply scale as much as 32 MB by means of this good contract mechanism, which is already deployed on all of the Qtum nodes.
What are the technical options and parameters of the Qtum blockchain?
Jackson Belove: Listed below are the technical options and parameters of the Qtum blockchain:
- Transaction mannequin: UTXO (Unspent Transaction Output) from bitcoin
- Good contract structure: EVM (Ethereum Digital Machine), including the x86 digital machine this yr.
- Block measurement: 2 million bytes, scalable utilizing on-chain DGP (Decentralized Governance Protocol) as much as 32 million bytes.
- Common block spacing: 128 seconds
- Good contract token protocol: QRC20, based mostly on Ethereum ERC20; QRC721 non-fungible tokens in growth
- Consensus algorithm: Proof of Stake, model 3.0, upgraded from Blackcoin
- Theoretical most TPS (Transactions Per Second): 70 TPS. A lot sooner utilizing Lightning Community and different Layer 2 applied sciences.
- Block reward: 4.Zero QTUM by means of December 2021 (halved each Four years), plus a share of transaction charges and fuel
- Genesis blocks preliminary creation: 100 million
- Most provide: 107.eight million in 25 years, present annual inflation 0.87%
From your personal viewpoint, do you contemplate Qtum to be one of many best and most interesting blockchain to make use of? Why?
John Scianna: First a part of your query, what milestones has Qtum hit within the first half of 2020:
Qtum launched the code for Offline Staking which is now stay on the Qtum testnet. This was probably the most requested function from the group and one thing I’m wanting ahead to personally. I’ve all the time needed to stake from my Ledger, and Offline staking will make this attainable. We additionally launched the White Paper for Phantom which illustrates the advantages of the protocol and the way we are going to deliver it to life.
With regard to Qtum being the simplest and most interesting blockchain, I’d say it’s the best blockchain to run a node for, and would be the best to develop into a validator for because you gained’t want “votes” like in different protocols. It’ll even be one of many best blockchains to delegate tokens to a staker as properly. For good contract UI, we nonetheless have some room to make it simpler and extra enjoyable. Proper now it’s not as straightforward accurately to work together with dapps, and we additionally need to make it tremendous straightforward to launch Phantom tokens and regular QRC 20 tokens.
Within the whitepaper, they clarify that sooner or later each digital machine will be capable of be adjusted to work on the Qtum blockchain, are you able to clarify how that will probably be achieved?
John Scianna: The best way digital machines run on Qtum acts as if it’s a unique layer from the blockchain as in comparison with ethereum the place even a fundamental transaction goes by means of the digital machine. For Qtum, solely good contracts undergo the digital machine so there’s a point of separation if something goes unsuitable with the digital machine. We have been in a position to do that with the Account Abstraction Layer which abstracts the accounts and permits them to work on the UTXO mannequin. Since we have been capable of take the 2 aside, we’re in a position so as to add extra digital machines on prime of qtum that may run in parallel. Qtum Neutron can even assist on this regard. In a sese, it’s a brilliant charged Account Abstraction Layer and can assist the x86 digital machine run on prime of Qtum as properly.
Is it attainable to stake QTUM from my personal pockets? I’ve Qtum saved up in my atomic pockets as a result of it’s decentralized and straightforward to swap with different crypto. Can I stake immediately from my Atomic pockets?
Jackson Belove: Thanks for the Query. Sure, I consider Atomic Pockets will add offline staking functionality. They approach it should work is that it is possible for you to to ship a transaction to delegate your deal with and permit a “Tremendous Staker” on-line node that may do the staking for you. Then your personal pockets can chill out and keep offline whereas the Tremendous Staker does the staking be just right for you and sends these block rewards proper again to your deal with.
