Qtum Foundation Becomes Newest Member of ACCESS

The Qtum Foundation is proud to announce that it is now a member of the Association of Cryptocurrency Enterprises and Startups in Singapore (ACCESS). ACCESS is the leading blockchain industry association fostering society’s transformation to this new technology in Southeast Asia.

“By joining ACCESS, Qtum is committed to engaging stakeholders and regulators in a productive manner as a cohesive group,” stated Patrick Dai, co-founded of Qtum. “The blockchain industry is emerging and constructive dialogues need to take place. It’s enlightening that this is able to happen in Singapore and Southeast Asia.”

ACCESS has been educating public and private institutions on the benefits of blockchain technology and cryptocurrencies since it was founded in May 2014. ACCESS aims to foster an open and clear dialogue between Singapore cryptocurrencies, blockchain businesses, and society at large.

Qtum shares the vision and mission of ACCESS, understanding the need for providing a united public voice and platform for the ASEAN cryptocurrency and blockchain community to better engage with private and governmental entities.
“On behalf of the community at ACCESS, we’re very honored to have Qtum join our association,” said Anson Zeall, chairman of ACCESS, adding, “Qtum is definitely an important addition to our community as it will continue to expand the blockchain ecosystem in ASEAN and beyond.”

thanks for the updates!

Is there an explanation how to withdraw qtum tokens from ico365?
does not work with myetherwallet address -> when adding address i did select ETH
anyone who can help? thank you

maybe ask ico365 directly

you can use any eth address to withdraw Qtum ERC20 token.

Version 1.10.0 released

* Redesigned two pages used to create smart contracts: bind payment and offer contract.  Now they look more like contract prose rather than web forms.  They also reduce manual entry and validate input for a few known oracles (validation is not perfect but prevents the most obvious mistakes).

* Added ability to vote in polls.  Now we can have referendums.  Poll Bot is added to the Bot Store, it assists in making a vote.  A vote is a small transaction that pays to yourself and is signed by your most funded addresses, the weight of the vote is the combined balance of the signing addresses.  Note that there is a privacy concern because by making a vote you associate a number of your addresses.  Source code of the poll bot:

* Fixed a bug that sometimes caused full clients to crash while syncing
* Fixed a bug that in rare circumstances led to creation of unspendable addresses during first run on Android wallets
* Fixed a bug that caused the wallet to erroneously complain about lack of coins when trying to send blackbytes
* Fixed creation of .desktop files on fresh Linux installs
* Other small bugfixes and improvements

You need to upgrade in order to vote.

that's great!

thanks for the updates

Qtum's weekly update is available on our Medium blog:

Community Updates

Forbes 30 Under 30

Patrick, Qtum’s co-founder, was recently selected to be on Forbes China’s selective 30 under 30 list. Patrick received the award for his notable work in consumer technology. The honor was given to those “who are challenging conventions and making an impact on the world.” Patrick is definitely challenging the traditional ways of thinking, and we our proud he is a part of our team.

Houston Bitcoin Meetup

Brett presented Qtum to members of Houston’s Bitcoin Meetup, this past week. Brett highlighted Qtum’s Account Abstraction Layer (AAL), our Decentralized Governance Protocol (DGP), and our EVM integration on the UTXO model. Two people in the audience were interested in starting their own blockchain-based project, and they asked questions about how Qtum got its foundational support.

Inkchain Event in Xi’an

This past week, Xiaolong “Stephen” Xu, Qtum core developer, spoke on a panel discussion at an Inkchain event in Xi’an. The discussion was framed around intellectual property and copyright infringement and how blockchain technology could help revolutionize the industry. Xiaolong noted that with blockchain technology, tracking payments for IP and verifying rights could be significantly improved.

In Other News…

Congrats to our team member and developer, Baiqiang Dong, for becoming a World Record holder in cubing! Baiqiang got the record for 3x3x3 fewest moves this past weekend at the China Championship in Xi’an.

Just to give a small update on what we are currently working on:


The current approach has totally disconnected the verification of work from the remaining verification routines (which are required to verify the consensus critical PoS operations). The reason for this approach were on the one hand some concerns, that people were feeling unsafe to execute "untrusted" code. On the other hand, the verification on each node would limit the amount of time a work-task may run: imagine, that a pretty complex job is on the network which takes around 5 minutes to execute. If miners work 5 minutes on it, everything is just fine. But if every node needs 5 minutes to verify the solution, it wouldn't take long until the entire network stalls.

So the solution was to use "super nodes" which do this complex verification stuff. Super nodes were meant to be super-efficient very fast computers capable of doing many many verification if a very short time. However, and you all are right, this means centralization and "blind trust". But in fact, a decentralized system is what we want.


Supernodes were working fine (see PoC from a few months ago) and they were using the native xel_miner application (written in C) to do the verification. Xel_miner was not only encapsulating the entire mining logic but also provided an API for super nodes, which could enqueue the transactions seen on the XEL network and semlessly receive the verification result for further processing.


We worked out a different (asymetric) verification method. This clearly limits the use cases to some extent but on the other hand it vastly increases the integrity of the entire blockchain.

The asymetric verification will allow us to code arbitrarily complex ElasticPL programs (they may run for hours) and define separate, much less complex verification functions (which finish in a blick of an eye). Verifcation routines must be coded very carefully (to avoid unwanted "trapdoor" solutions which do not reflect what we actually want) but there will be a developers guide sooner or later.

Now, this scheme allows us to move the verification back into the java code base and again perform the verification on all nodes. (All is not strictly correct, as you will learn in the next point). This way, we drop any super nodes and guard nodes, and avoid any kind of centralization at all.

Work should not be consensus critical:

In an early version of Elastic (way before the super node proof-of-concept) work transactions were regular transactions and were consensus critical. Probably everyone of those who followed the progress remember the chain forks due to some unforseeable error (differencies in floating point operations on different platforms could lead to a hard fork ... yes).

We do not want this, so we:
1. Do not model the work communication as actual transactions but as binary messages transmitted over the Elastic messaging system.
2. Only do work processing when a "work=true" flag is set in the config. If you do not want to participate in any working activity, you can leave this feature off and you will not participate in any verification whatsoever (good for those who do not trust any code). But if you decide to turn it on later on, you can just catch up by synching all new "unparsed" messages of this kind. This is possible, because the "sort-of parallel chain encoded in those binary messages" and the actual blockchain do not need to be in sync at any point. Well, let's not become too technical here!

The cool thing is: If something goes wrong with one work package, other work packages and, even more important, the entire blockchain remains unaffected by it. How the work-payments will be modelled in this "unconventional approach" will be revealed at a later point in time :wink:

Now comes the actual task:

And now comes the task, which causes so much work at the moment and which eats up every free second that we have: We have to port the C ElasticPL to JAVA ElasticPL - in a way, that both work in the same way, in all cases on all platforms.

I am half way through (all of it was done in the last week alone - it's been "burnout-ish"):



Contribute to ElasticPLJava development by creating an account on GitHub.
What is there is the Tokenizing (splitting up code into tokens) and the construction of the Abstract Syntax Tree.
This was pretty hard - and this basically defines the entire ElasticPL language. What is still missing is the interpreter, and this is what I will be doing next.

If someone wants to play around, just open the project linked above in IntelliJ Idea and launch it. You will not see much, but those of you, who really want to dig into it, will quickly find out how to verify that the AST tree is actually built correctly. Also: feel free to report any bugs or any inconsistencies between the C and the Java version.

Disclosure: I currently do hold XEL coins.

When is next airdrop for Byteball?

   July 9, 2017 at 04:07 UTC

Beware of change addresses in your BTC wallet AND in your byteball wallet for the next distribution round!
Byteball distribution companion helps you.

          Is you address properly linked?
          Is your linked BTC balance what you expected?
          Are all your bytes on your byteball linked address?
          How much will you receive?

+Bookmark. Once distribution has started you can follow in near real time when bytes arrive in your wallet. Enjoy!
do we have an explorer for blackbyte?

thank you

137  Alternate cryptocurrencies / Announcements (Altcoins) / Re: BYTEBALL: Totally new consensus algorithm + private untraceable payments on: June 30, 2017, 08:06:07 AM
I recommend you to wait for my Byteball test report. I have already spotted things which need to be improved, once they are fixed the price will shoot up. Just accumulate more GBs now.

First, let's discuss the main problems with Iota vs Byteball:

1)  Anti-spam PoW (unprofitable PoW) for emails was entirely designed for one-offs.  You put in some labor and the state changes from 0 to 1 once it's been satisfied and this information is now meaningless and can be thrown away afterwards.  Satoshi decided that in order to chain the past to the future in a continous ledger, he would need to create a linked list with a get rich quick scheme built on top of it, otherwise there are no incentives for the burden associated with the cost of holding this data forever.  

It seems like IOTA was invented (unprofitable PoW) while ignoring everything Satoshi learned needed to be utilized in order to launch the bitcoin scheme.  True, Iota could utilize a form of pruning, thus correcting the incentives problem and dragging it back to more like email PoW in nature, but then you have a very fragile, unsound money system with no valid form of state recovery if it goes down.

I'm not saying bitcoin is sound money, because it's not.  It doesn't function as a store of value due to price floor being recursive based on it's own demand, meaning you can always mine an endless stream of coins as transaction fees at the new floor and the floor can crater to nothingness at any time unless bitcoin was the unit of account of something (but it never will be since it doesn't function as a store of value - chicken and egg scenario).

Most attempts to increase bitcoin scalability in altcoins, and thus lower redundancy, seem to make it even less sound money where you can no longer trick people into believing it's money at all.  People will see how fragile they are and treat them as they should be, just as a throwaway currency like airline miles instead of pretending they are a valid store of value like gold or silver.

As for Byteball:

2)  Is there really a purpose in a, hmm how to describe it in general, a branching/multi-threaded/non-linear system like a DAG if you're just using bitshares-style consensus to force convergence and make it linear in a single path again?

some good point here.

Quote from: skycoin on March 16, 2017, 04:54:31 PM


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.

i like this post, if you are new to Qtum, you should read it.

Why some accounts give me a message about Qtum
But I myself did not participate in ICO qtum??

someone is attack Qtum and spam people's inbox...
