Nội dung chi tiết

Phần 1: Richie hỏi Patrick&Jordan 5 câu hỏi

Câu 1: First off, Qtum has been around for a few years, it’s sort of an East meets West story. Why don’t we start off by you two telling us how you two met and built the team?

Trả lời: It was around August 2016, we released the first Version of the Qtum white paper, the basic idea was to build smart contract on bitcoin blockchain. This was roughly idea at that time, then, we needed to find the best developer to lead it and build it. Earlz has a good reputation on the Altcoin code review and auditing. One of our common connections talked to earlz and found out we share the same vision for the Qtum technology and blockchain industry. Then we started the whole journey.

We met initially through a mutual friend, Mike. I was skeptical at first when I met him, but after talking over skype and such I saw that Patrick had a very good vision for what would become Qtum. I was instantly interested in the project and basically came on board to figure out how to fit Patrick’s vision into a technical reality.

Patrick actually built most of the early team and knew a lot of great people that then knew other great people. I think one of our biggest advantrages in the beginning was a great early team

Câu 2: Jordan can you tell us about your unique perspectives of how you see China compared to the West and Patrick can you also give the same comparison?

I think for blockchain industry, the west mainly is technology driven while china is more like market driven. in the west, there are a lot of team doing some hard core tech or deep research, but it’s not that much in China. I hope the Chinese team can catch up on that area.

I think China is quite interesting and though there are plenty of similarities to where I’m use to in the US, it’s also vastly different. In many ways it is technologically more advanced, and I think this is why blockchain is particularly interesting as part of a east meets west kind of story. I think there is a lot of benefit to bringing some eastern mindsets to the west and western mindsets to the east regarding financial and payment technology, especially concerning how people actually use them. We also gain a very practical mindset from the east, which I think is especially different from many projects in the blockchain space

Câu 3: It has been a tumultuous year and a half for crypto. How do you see overall blockchain developing going forward and what are the opportunities for Qtum?

The industry is recovering from the bubble in 2017 and early 2018 now. Bitcoin is still the most dominant in the market. Because bitcoin acts as an alternative asset and better currency it is getting more and more attention every year. The bitcoin story is still the continuous story that keeps moving the industry forward. But people are channeling the Dapps story recently. Most of the Dapps will not work. The opportunity for Qtum is 2 areas, first Qtum has the potential to be a regulated digital asset in next few years. Second, Qtum is working on a few directions to make Qtum a better platform for real blockchain applications. We are working on scaling solution, contract based consensus algorithms, and confidential assets, these new features will make Qtum become more decentralized, scale, and offer greater privacy.

Câu 4: Qtum has issued many soft fork updates since it’s release in 2017. Why did you feel the need for a hard fork, and how much more difficult is it to coordinate something where all the stakeholders are aligned?

Yes, Qtum has had many versions been released since the first mainnet in September 2017, we had 38 releases in the last 2 years: https://github.com/qtumproject/qtum (https://github.com/qtumproject/qtum), for some Qtum improvements, if you are not breaking the consensus rules, then it’s a soft fork, it’s backwards compatible, even you do not update to the new version, you can still use the old wallet. For the fork that activated yesterday, you have to update to the new version, otherwise you will be on a forked chain and can not spend that coin on the new blockchain. It’s harder to do a hardfork as it need more testing and more cooperation with all exchanges, stakers, and wallet service providers. We needed to make sure all Qtum related services updated to the new version.

I think with this fork it’s not very difficult to align. It adds new features and stability, we’re not doing anything controversial here or anything that would put anyone in the ecosystem. This hard fork specifically was required because we were changing a core network protocol, the difficulty algorithmn. This was necessary to properly fix a long stanging issue with Qtum block times. I know hard forks can be a real pain to deal with for the ecosystem, but I think the gain in stability is definitely worth it, and plus plenty of new features on the smart contract platform side, including private asset support in smart contracts (zkSnarks) and true third partty fees enabling people to easily interact with projects on the Qtum network without ever needing ot actually own any Qtum

Câu 5: What is coming in the future for Qtum? What is the cool stuff you are working on? Will there be more hard forks?

First, we are still keeping all the great work going and keep developing more exciting technology for Qtum. and We achieved something until now, like we have the third most full nodes amount only after Bitcoin and Ethereum and if you count the POS network, we have the most Full Nodes among all POS Blockchain. It’s one of the most decentralized cryptocurrency and platform.

We are working on the x86 virtual machine/neutron and also smart contract based staking consensus. At the same time, we think privacy is very important for financial businesses, we are working some privacy solutions for QRC20 tokens, later you can release some Confidential Tokens through Qtum smart contracts. We are also doing some research on how to involve Cloud Services for Qtum network to make Qtum become a better infrastructure for future blockchain applications. Qtum’s mission is still to be one of the best infrastructures for the blockchain industry in the next 3-5 years, and we will keep building!

The coolest stuff we are working on is a new smart contract platform called Qtum Neutron (previously “x86”). This will enable a lot more smart contract use cases, with features being designed specifically for scaling and to reduce node resource requirements, along with substantial security and usability improvements (ie, using Rust for writing smart contracts, upgradeable smart contracts, better SPV support for smart contracts, etc)

Phần 3: Cộng đồng sẽ hỏi Patrick&Jordan

Một vài câu hỏi hay được chọn

Câu 1: What is the roadmap for the next six and twelve months? What use cases or challenges are you trying to solve? What is the future direction of this project?

for next six monthly, we are working on the smart contract based staking, which you can delegate your coin to the smart contract in the Qtum network. for the next 12 months, we will have the first version for Qtum X86 ready. For the Usecase, we are scaling the Qtum for all applications which want Blockchain features, we plan to involve with the cloud to offer better support for Blockchain applications. The direction of this Project is be the best Blockchain Platform in the next 3-5 years!

Câu 2: What’s the qtum neutron’s top challenge for you Jordan?

The biggest challenge is that we want to take it kind of like… to the next level, not just a simple VM that’s a bit better than the existing EVM. We want something that enables entirely new use cases and massive improvements. This has caused the design to change significantly from the first prototype that was created and has caused some delays, but the end result will be worth it!

Câu 3: How will the Mimble Wimble (MW) technology help to secure privacy? Can you through more light on MW?

We plan to implement MW through precompiled smart contract on Qtum, so you can release Confidential QRC20 token on Qtum. While for most of other smart contract Platform, you can release transparent tokens.

Câu 4: How do you think X86 VM will be a better way for developers to build dAPPS and smart contracts?

What will be the initial blockchains that UNITA will use to exchange data and value?

What is the advantagr of using Qtum over its competitors in the industry?

How do you think X86 VM will be a better way for developers to build dAPPS and smart contracts?

For sure! You’ll be capable of writing smart contracts in the established language Rust, and it will also expose some of the features unique to Qtum that don’t really fit into the EVM, such as exposing some features of our UTXO model, multiple address types, etc. This is called Qtum Neutron now, because it’s bigger than x86. We plan on later also adding WASM virtual machine support, but while keeping the same smart contract APIs. IT’s designed to truly work with multiple VMs ont he platform

Câu 5: Explain more about your Abstract Account Layer (AAL), and how does this maintain blockchain performance and optimize it?

Qtum boasts the biggest PoS peer to peer network, with full nodes, HOW WERE YOU ABLE TO PULL OFF THIS? WHAT MAJOR SETBACKS DID YOU ENCOUNTER DURING LAUNCH AND WHAT MILESTONES HAVE YOU ACHIEVED?

You have plans to Scaling improvements which will bring Qtum to 50k TPS? What does this mean for we HOLDERS AND USERS? What would be sacrificed to achieve 50 TPS?

Qtum boasts the biggest PoS peer to peer network, with full nodes, HOW WERE YOU ABLE TO PULL OFF THIS? WHAT MAJOR SETBACKS DID YOU ENCOUNTER DURING LAUNCH AND WHAT MILESTONES HAVE YOU ACHIEVED?

We used some existing technology but greatly simplified it (specifically no timestamps in transactions) to increase the security. It was a lot of work primarily in testing and optimizing the staker to work well for smart contracts. This was the biggest problem, initially we had a DoS vuln in the staker just because of it’s naive design. It took a lot of hours to figure out how to make it work properly and have no exploits

You have plans to Scaling improvements which will bring Qtum to 50k TPS? What does this mean for we HOLDERS AND USERS? What would be sacrificed to achieve 50 TPS?

We already are ~70TPS in our network. We plan on taking it beyond that by using layer2 solutions and Qtum being about like the safe and secure but slow settlement layer.. like, you don’t pay for coffee with a bank wire. Layer2 will take over for simple day to day transactions. This is an area of heavy research for us

Câu 6: Q1 ) How long do you think it will take for cryptocurrency to become mainstream?
Q2) If you were to summarize your project in one word, what would it be?
Q3 )What’s your outlook on the future of cryptocurrencies? What can we do to keep increasing adoption?
Q4 )I am big fan of your team. Are there any plans to hold a meetup in Indonesia?
Q5) QTUM !! Privacy and Smart Contracts??
Q6) Is the first satellite currently in orbit working as a Qtum node — similar to what my laptop computer does with PoS which connects to the Qtum main chain and downloads each block to PoS?

How long do you think it will take for cryptocurrency to become mainstream?

I think we’re a ways off, but making good strides. Maybe 5-10 years until you’re using blockchain technology and not even aware of it. Blockchain needs to be seemless. No one thinks “Oh I love facebook because they use ReactJS” or something, the technology enables things previously impossible and is seemless to users

Q2) If you were to summarize your project in one word, what would it be?
Not one word, but how about “practical blockchain”. Our focus has been on making blockchain technology practical, not “theoretically possible”

Câu 7:

Q1: I read a lot about QTUM, all are positive and good. But my question is what is behind QTUM that maintains its accuracy and ensures the whole system is working as per requirement? Is there any centralized server to check whether everything is working fine?

Q2: What programming language are you using and why?

Q3: How have you been able to survive this longest bear market and please explain more about your staking and consensus algorithm (QTUM)?

Q1: I read a lot about QTUM, all are positive and good. But my question is what is behind QTUM that maintains its accuracy and ensures the whole system is working as per requirement? Is there any centralized server to check whether everything is working fine?

Along with auditing and a very strong testing mindset shared across our developers, one of the cool low level tech things is that we actually rebuild blocks and then validate “is what we expected to happen the same as what the actual block says”.. Kinda hard to explain, but we do more than just a simple set of rule validation on blocks, instead we do that plus rebuilding blocks to ensure that everything lines up. It’s actually saved Qtum from an exploit or two in the past

Q2: What programming language are you using and why?

Qtum Core is written in C++ but as part ot the Qtum Neutron project we are introducing a lot of Rust written code. I think Rust is the ideal language because it’s high performance, but yet has a very strong focus on safety and includes a number of nice modern features like a built in testing suite and strong package ecosystem

Q8:

1 – What is the crucial thing, in your opinion,that would increase adoption of #QTUM and possibly the rest of crypto. What’s the #QTUM economic model and how will it is architecture ensure scarcity of the token and help to growth token price ?

2- QTUM is compatible with BTC & ETH Blockchain while both are a competitor of QTUM, Why you choose to make both compatible with QTUM?

1 Bitcoin is like the index for whole Blockchain industry right now, it’s good in short term, but bad in long term if we really want Blockchain. at the beginning, Ethereum want to extend the flexibility of the crypto currency,so they add VM to enable smart contract. but the Problem is all Platform is using the same logic from bitcoin p2p network… it’s a synchronous network.. it’s good for crypto currency design , but bad for applications.. because for applications. you do not really need 8000 back up across the world.. that’s the reason i feel.. we do not really have a good Platform for applications in the whole industry.. if we want applications.. we need out of box design..we need something Beyond bitcoin (for currency) and Ethereum （for smart contracts）.. i think that’s a direction the whole industry is looking for. and Qtum have some ideas on that and we are working on that direction too. if we need better adoption.. we need application driven.. we need consumer apps rather than just another token or another coin. people will realize it later.
