I'm sure marketing will want to do a more formal release, but heads up that we now have a compiled Windows version of the Qtum Sparknet wallet. It's available on the release page here: https://github.com/qtumproject/qtum/releases/tag/testnet-sparknet

What will Qtum do differently than Ethereum to deal with scalability issues?

It's pretty clear.. On the day of launch the website went down, got hacked, things were slowed down, etc. all due to the hacks paired with the spamming. I think it's pretty clear that someone is trying to throw some FUD here to scare people away and load up..

Separately for Gleb.. US Investors were actually able to participate in the ICO through Bizhongchou and I can verify this works.

Qtum Unveils World’s First Proof-of-Stake Smart Contracts Platform

The Qtum Foundation is pleased to announce the launch of Sparknet, the first public test of its innovative blockchain platform, which combines crucial advantages of Bitcoin, Ethereum’s Virtual Machine and proof-of-stake consensus.

The Qtum (pronounced Quantum) blockchain model was inspired by the rivalry between proponent developers of the world’s most active blockchain communities, said Qtum co-founder Patrick Dai.

“We want to illustrate efficient scalability and compatibility between blockchain technologies,” said Dai. Qtum raised $15.6 million in a crowdsale in March.

The Qtum blockchain operates according to the Unspent Transaction Output (UTXO) model, which ensures consistency in transactions and the traceability of tokens. At the same time, a virtual machine for smart contracts is layered on top of Qtum’s blockchain, which presents to developers a best-of-both-worlds architecture for the construction of decentralized mobile applications and other blockchain-based ventures.

Co-founder Jordan Earls, who leads Qtum’s team of almost two-dozen developers, said the testnet would feature an Ethereum Virtual Machine smart contract implementation along with Qtum’s proof-of-stake protocol.

“I’m ready to get this in the hands of the community and see what everyone’s response to it will be, in particular, what features other developers can come up with,” said Earls.

“The Qtum team continues to execute and build what can be one of the most exciting and innovative railroads in the blockchain ecosystem,” said Matthew Roszak, Qtum Angel investor and co-founder of Bloq.

Six decentralized applications are already being built for the blockchain, Dai said. Among the applications are a peer-to-peer mobile streaming platform and a prediction market.

While these applications are geared to the Chinese market, the Qtum blockchain will appeal to a global audience, accessible to all developers.

“Like many others around the world, I’m eagerly awaiting the launch,” said Roger Ver, a Qtum Angel investor who has been investing in bitcoin startups since the beginning.

To get developers familiar with Qtum, the Foundation is sponsoring a hackathon in Moscow on July 1-2. For more information, visit blockchainhack.ru.

no, i think the things matter is validation nodes, if this 8 validations node went down, this system worth nothing

that's the reason why i say this will never become a currency.. just a hype.

but it's doesn't matter stupid people will buy this.

and price will still go up ..

You obviously did not notice that at https://www.antshares.org/ the number of FULL NODES at this point is 417. I think the only requirement to become a full node is having 10,000 ANS and running the proper Linux system whilst meeting all technical specifications. Everyone else who runs it is in effect a light node. If you read the network protocol (https://github.com/AntShares/AntShares/wiki/Network-Protocol), you will see that ANS holders can vote on validator candidates and it can be increased to a maximum of 1024. Validator candidates can be accepted, rejected or revoked. This is a continuous process. Let's give another example: Does a Presidential candidate run the country? No, it is a candidate who can be elected by others. That is the same with the validator candidates you are referring to. If you noticed carefully, 7 are effective and 1 was revoked. This appears to be an old list for selecting candidates. The number that matters is the 417 FULL NODES. This number is increasingly rapidly in the last few days. Contrary to Bitcoin ANS holders get to vote on which parties they trust to run the system.

Qtum, will probably replace ethereum because it is simpler and has fewer problems. The UXTO model is much cleaner. They have a lot of previous developers and have already done two previous coins and are the best team I have seen so far.


I won't trust dev that promoting qtum-SCAM.....

I have not looked at qtum's code.

We know the qtum founder and he is one of the largest investors in Skycoin from four years ago, before qtum or any of this. Some of the people around him are legendary scammers, but he is not a scammer.

I think Patricks role in the bitbay situation is exaggerated. I read through the arguments and it just sounds like drama.

Many of the people in the Bitcoin community are sociopaths. They often steal things or cause drama, then immediately blame it or scapegoat it on someone else. They are not even done stealing the money, before they go on campaign of moral indignation against the fall person.

I think Patrick was blamed for Bitbay because his personality makes him an easy victim for sociopaths and the human predators in the bitcoin community. There are people walking around, sizing people up and trying to determine whether they can manipulate someone, setup a scam, steal things and who is going to be gullible or a fall person.

If you knew the people involved, you would understand what the social dynamic is.

>Also how can you be so confident qtum is going to replace ETH based on it's tech when they haven't released code yet?

Ethereum is using an accounts model, like Ripple. Which is anti-blockchain and anti-privacy and very traceable. It is against the philosophy of Bitcoin.

All coins going forward will be on the UXTO model and it is best practice for blockchain. Moving turing complete smart contracts off of accounts model and onto UXTO is extremely important and that is what qtum appears to be doing.

We need to figure out how to do general computation on a UXTO model. Instead of being restrained to the Ripple/Ethereum accounts model.

I think they will get closer to the goal, but only get there part way
- thin client for smart contracts (major limitation for existing system)
- moving smart contracts onto UXTO (major milestone)

I do not know if qtum has succeeded, but they seem to be going in right direction. I talked to one of their technical leads and they were focused on "Getting it working with something we can do now" and then incremental improvement over time. So first implementing the Ethereum virtual machine on top of UXTO, then working out the research problems for a native turing complete UXTO language later.

I do not know if there is a way to full UXTO while still having "gas". I think you will need to get rid of the "gas". In the ethereum model to take full advantage. I do not know if qtum will be able to go far enough in doing that, but is heading in the correct direction.

Ethereum tries to be both a token and a computer.
- we started with pure tokens (Bitcoin)
- then we added a computer to the tokens (Ethereum)
- now we just trying to figure out how to build  pure computer on UXTO
- Then once we have the computer, the tokens or coins just become a program or entity running on this "distributed computer"

Bitcoin, Ethereum, qtum, byteballs, etc are just stepping stones. Towards a final solution. None of these will exist or be relevant in ten years. We are in an age of transition and I am looking at the projects that are getting closer to the goal, in a pure mathematical sense.

Even Skycoin is being ripped up and its foundations constantly rewritten when it is advantageous to do so. Bitcoin is static and relatively unchanging, while Ethereum has been able to get the community to accept constant small changes.

Skycoin is on a punctuated equilibrium model, where we do bug fixes and polishing, then completely rip up and rebuild the foundation as needed, then go back to bug fixes and polishing.

Right now, we are exploring new networking primitives and the advantage of immutable data structures, but are still on blockchain. Putting EVM on UXTO is heading towards immutable data structures from the perspective of computation, while we are heading towards immutable data structures from the path of consensus, networking and simplifying object synchronization protocols.

One of the pilots that is being spun out of that project is the distibuted, peer-to-peer social media platform built upon immutable data structures and peer-to-peer object replication. For this Skycoin chose a public key, cryptographic publisher/subscriber model and DAG immutable object tree. While Ethereum's project chose a Kadmelia DHT block storage model.

Ignoring the individuals and the drama, I am just looking at the "future direction" and who is heading in that direction.

>Also how can you be so confident qtum is going to replace ETH based on it's tech when they haven't released code yet?

I am not confident it will replace Ethereum. At the start, it will be equivalent to ethereum in terms of being able to run the Ethereum Virtual Machine (EVM) on top of qtum with UXTO. Then they will do a native language.

It will depend on the implementation. I do not know if qtum has succeeded, but they seem to be going in right direction.

Similarly, Byteballs may fail or may not exist in ten years, but they are pioneering the first experiments into replacing the Blockchain with a DAG. Which we have been considering for several years now.

Similarly, Bitcoin was the first but people are getting used to the idea that it will not be the final or best cryptocurrency. That it was just the first generation and that we can build better and improve it substantially.



thank you skycoin dev, because of you, i brought into qtum and made some money.
