Daily Test Network Update #3:

Leading up to our June 28th Test Network release, we will be providing daily updates that explain the work that goes on behind the scenes. Yesterday we went over the 5 more points, and today we focus a lot on the Proof-of-Stake portion of the Test Network.

11, Change all output strings Bitcoin -> Qtum, BTC -> QTUM

Replace all instances of bitcoin and BTC with qtum and QTUM (Just the output strings, not the actual class/variable names and not the code comments)

12, Increase Script limits to suitable values

There are a number of limits in vanilla Bitcoin that restrict our usage of smart contracts. These limits should be relaxed:

maximum data push size: 1Mb

maximum stack size: 1Mb

Test for other limits that we run into with large scripts caused by contracts.

13, Consensus/Chain parameters for PoS

Consensus/chain parameters for PoS

The consensus provide parameters that will affect the creation of new blocks in the network.

The PoS limit need to be added in order to determine the initial difficulty for PoS.

The halving interval is 4 years (target) and there will be 7 halving intervals.

Block target is set to 128 seconds.

4 tokens per Block (Approximately 1% inflation per year for 4 years)
2 tokens (Slightly more than .5% inflation per year for 4 years based on 100 million original tokens .5% of 104~ million after 4 years)
1 token
.5 tokens
.25 tokens
.125 tokens
.0625 tokens

The last PoW block need to be defined and set to 5000 for the main net. The reward for PoW block is 20000 coins, the reward for PoS block is 4 coins. The Proof-of-Work blocks will be mined by the Qtum development team.

14 , Update of block/block-header parameters for PoS

The general rule for the header is to keep it as small as possible.

Four parameters are needed for PoS in order to work:

1) Block signature, that is the signature of the whole block, signed by the block creator

2) Block type (Proof Of Work or Proof Of Stake)

3) Previous stake location, need in order to confirm the block validity, mandatory for PoS

4) Staking time, the time when the staking transaction was created, mandatory for PoS

Block signature must be a parameter. The parameter need to be in the header due to the segregated witness which split the block delivery into header and transactions that can be required from any user.
The other parameters can be extracted from the PoS transaction. Whether or not to include those 3 parameters in the header too can be discussed. The block header is downloaded before the whole block, not including those parameters in the header will prevent doing PoS checks to the header before downloading the whole block. Blackcoin download the whole block before the checks and put those parameters into the Block.

15 ,Proof of Work/Stake Kernel Update

The source code for PoW and PoS kernel is kept into the files:


The location of the files is according to master-pos, in Blackcoin the location is kernel.h and kernel.cpp.

We need to decide if we will keep it or use different structure for organization of the code for PoW and PoS kernel.
The version of the stake modifier that will be used is the second version.
Block difficulty, masks, modifiers, time-stamps are all used here, so this is important parts for PoS.

Please see the Roadmap below for more information:

Please remember that we have an event in Shanghai on the 28th so please RSVP if you plan on attending:

Qtum will also be sponsoring a Hackathon in Russia, with 8500 QTUM tokens. For more information, please see:

Qtum is hiring! If you have experience in Blockchain technology, and can handle working in a changing industry, get in touch with us.

how many people will go to the hackathon?

# Note autogen will prompt to install some more dependencies if needed
make -j2

Qtum Sparknet Usage and Information

Please see:

Qtum is a decentralized blockchain project built on Bitcoin's UTXO model, but with support for Ethereum Virtual Machine based smart contracts. It achieves this through the revolutionary Account Abstraction Layer. For more general information about Qtum as well as links to join our community, go to

Welcome to Qtum Sparknet, the first public testnet for the Qtum blockchain. Sparknet is designed primarily for developers, and as such documentation at this point will be technical and suited more for developers. The mainnet is expected to be released in September and will be suited for the general public. Testnet tokens do not hold any value and should not be traded for any monetary instruments. The testnet can be reset or forked at anytime as deemed necessary for development. Sparknet does not include support for Mutualized Proof Of Stake, or for the Decentralized Governance Protocol. Both of these features are implemented, and their code is available on alternative branches (check the pull requests), but have not been tested and proven stable enough to include in this testnet. They will be implemented in the 2nd public testnet for Qtum.

Using Smart Contracts with Qtum

The smart contract interface in Qtum still requires some technical knowledge. The GUI is not completed yet, so all smart contract interation must happen either using qtum-cli at the command line, or in the debug window of qtum-qt.

To demonstrate how to deploy and interact with a simple we will use this contract:

pragma solidity ^0.4.0;

contract QtumTest {
   uint storedNumber;
   function QtumTest() {
   function setNumber(uint number) public{
       storedNumber = number;
   function logNumber() constant public{
        log1("storedNumber", uintToBytes(storedNumber));
   function returnNumber() constant public returns (uint){
       return storedNumber;
   function deposit() public payable{
   function withdraw() public{
   //utility function
   function uintToBytes(uint v) constant returns (bytes32 ret) {
       if (v == 0) {
           ret = '0';
       else {
           while (v > 0) {
               ret = bytes32(uint(ret) / (2 ** 8));
               ret |= bytes32(((v % 10) + 48) * 2 ** (8 * 31));
               v /= 10;
       return ret;

It compiles to the following EVM bytecode

And finally, has the following JSON interface file:


This info can easily be retrieved for any contract by using Browser Solidity, inputing your contract's source code, and then on the right hand side clicking "contract details"[/size]

(note, if using the debug window in the Qtum Qt application, don't include ./qtum-cli in the commands)

First, we need to deploy the contract:

./qtum-cli createcontract 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 300000
Note that the last number is the gas limit for this transaction. The default value is not large enough for this contract, so we increase it to 300,000 gas.

This should result in something like so:

  "txid": "72b0e0576d289c1e4e6c777431e4845f77d0884d3b3cff0387a5f4a1a3a874ea",
  "sender": "qZbjaE8N18ZU1m7851G7QGhvxKL74SRBTt",
  "hash160": "aff3e34ab836edb8d214a993d9da105915e4a6e9",
  "address": "5bde092dbecb84ea1a229b4c5b25dfc9cdc674d9"

Now, you should store the address in a variable so it's easy to track:

export CONTRACT=5bde092dbecb84ea1a229b4c5b25dfc9cdc674d9
Now wait for your contract to be included in a block. You should be able to confirm it made it into a block by using:

./qtum-cli getaccountinfo $CONTRACT
If you get a message saying "Address does not exist", then either your transaction has not yet been included in a block (you can confirm this with getrawtransaction and your txid), or you did not provide enough gas for the contract to be executed and persisted into the blockchain. If the contract was successfully executed and persisted in the blockchain, you should see something like this:


  "address": "5bde092dbecb84ea1a229b4c5b25dfc9cdc674d9",
  "balance": 0,
  "storage": {
    "290decd9548b62a8d60345a988386fc84ba6bc95484008f6362f93160ef3e563": {
      "0000000000000000000000000000000000000000000000000000000000000000": "0000000000000000000000000000000000000000000000000000000000000001"
  "code": "..."

In order to interact with the contract, you must create raw ABI data from the interface JSON file. The easiest tool to assist in this is ethabi,

Make sure the JSON file is saved somewhere, we will call it interface.json.

In order to get the storedNumber variable we use the returnNumber() function. We can construct the ABI values by using ethabi:

ethabi encode function ~/interface.json returnNumber
The result of this is:


Now, because we are not changing state, we use callcontract:

./qtum-cli callcontract $CONTRACT 3450bd6a
This results in a lot of data that can be useful in different contexts (including gas estimates), but we are only concerned about the output field, which is the value of storedNumber

    "log": [

To change the storedNumber we can do an on-chain execution using sendtocontract. First, we need the ABI data:

ethabi encode function ~/interface.json setNumber -p 123456 --lenient
Note we use --lenient so that we do not need to provide a full 256bit value as a parameter. Now, we can execute the contract directly:

./qtum-cli sendtocontract $CONTRACT 3fb5c1cb000000000000000000000000000000000000000000000000000000000001e240
Afterwards, we can call returnNumber() again and check the output field:

"output": "000000000000000000000000000000000000000000000000000000000001e240",
This is 123456 encoded as hex.

You can also use the logNumber() function in order to generate logs. If your node was started with -record-log-opcodes, then the file vmExecLogs.json will contain any log operations that occur on the blockchain. This is what is used for events on the Ethereum blockchain, and eventually it is our intention to bring similar functionality to Qtum.

You can also deposit and withdraw coins from this test contract using the deposit() and withdraw() functions.

The ABI value for deposit is d0e30db0 and the ABI value for withdraw is 3ccfd60b

This will send 10 tokens to the contract:

./qtum-cli sendtocontract $CONTRACT d0e30db0 10

And then, to withdraw them it's also very simple:

./qtum-cli sendtocontract $CONTRACT 3ccfd60b

If you want to control the exact address that the contract sends coins to, you can also explicitly specify the sender. Note that you must be capable of sending coins from that address (you can't use someone elses address). One of my wallet addresses is qZbjaE8N18ZU1m7851G7QGhvxKL74SRBTt, so I'll use that:

./qtum-cli sendtocontract $CONTRACT 3ccfd60b 0 190000 0.0000001 qZbjaE8N18ZU1m7851G7QGhvxKL74SRBTt

Note that if you get the error "Sender address does not have any unspent outputs", then you should send some coins to that address (they must be spent in order to prove that you own that address). This can be accomplished with any amount of coins:

./qtum-cli sendtoaddress qZbjaE8N18ZU1m7851G7QGhvxKL74SRBTt 0.001

There is no need to wait for this transaction to confirm, it can be followed immediately by the sendtocontract command:

./qtum-cli sendtocontract $CONTRACT 3ccfd60b 0 190000 0.0000001 qZbjaE8N18ZU1m7851G7QGhvxKL74SRBTt

When creating this contract transaction, nothing will immediately happen, when the transaction is put into a block though a new transaction will appear in a block which will send any coins owned by the contract to the pubkeyhash address qZbjaE8N18ZU1m7851G7QGhvxKL74SRBTt


Q: "I used createcontract, but can't call my contract and it's not in listcontract" A: You probably did not provide enough gas for the contract's constructor to be executed and it's code persisted in the blockchain. The vm.log file should confirm this by saying how much gas was needed

Q: "I sent a large amount of gas but I never got a refund" A: Refunds are generated from the coinstake transaction, so you must wait 500 blocks for the gas refund to mature before it can be spent again

Q: "I used -reindex and now my node is taking forever to resync" A: Currently when doing a reindex, all contracts are reprocessed, so in a chain with many contract executions this can add up to a significant amount of time. This will be made faster in the future, as well as the initial syncing speed of nodes

Q: "I think I found a bug in Qtum" A: Please report any bugs at
New Qtum RPC Commands

Qtum supports all of the RPC commands supported by Bitcoin Core, but also includes the following commands unique to Qtum:

createcontract - This will create and deploy a new smart contract to the Qtum blockchain. This requires gas.
callcontract - This will interact with an already deployed smart contract on the Qtum blockchain, with all computation taking place off-chain and no persistence to the blockchain. This does not require gas
sendtocontract - This will interact with an already deployed smart contract on the Qtum blockchain. All computation takes place on-chain and any state changes will be persisted to the blockchain. This allows tokens to be sent to a smart contract. This requires gas.
getaccountinfo - This will show some low level information about a contract, including the contract's bytecode, stored data, and balance on the blockchain.
listcontracts - This will output a list of currently deployed contract addresses with their respective balance. This RPC call may change or be removed in the future.
reservebalance - This will reserve a set amount of coins so that they do not participate in staking. If you reserve as many or more coins than are in your wallet, then you will not participate at all in staking and block creation for the network.
getstakinginfo - This will show some info about the current node's staking status, including network difficulty and expected time (in seconds) until staking a new block.
New Qtum Command Line Arguments

Qtum supports all of the usual command line arguments that Bitcoin Core supports. In addition it adds the following new command line arguments:

-record-log-opcodes - This will create a new log file in the Qtum data directory (usually ~/.qtum) named vmExecLogs.json, where any EVM LOG opcode is logged along with topics and data that the contract requested be logged.
Untested features

Some features included in Bitcoin Core have not been tested in it's porting to Qtum. This includes:


EVM Smart Contract Changes and Limitations

Because of Qtum's underlying technical differences, there are a few operations that can have different results or limitations when executed in Qtum than when compared to Ethereum.

These include the following, though there may be others introduced in the future:

The gas schedule for Qtum is different from Ethereum. Certain operations are more or less expensive. As such, gas cost estimators designed for Ethereum will not give accurate results for Qtum. We will develop our own gas estimating tools as well as fully documenting these differences at a later date.

block.coinbase or the COINBASE opcode currently is not supported and will only return 0. When MPoS is released in the 2nd testnet this should be functioning as expected
block.number will return the previous block height before this block containing the contract's execution
block.difficulty will return the previous block's difficulty
`block.timestamp will return the previous block's timestamp
block.blockhash(n) will return 0 when n is the current block height (block.number+1), similar to Ethereum
sender will return 0 when the coins spent (vin[0].prevout) are from a non-standard transaction. It will return the pubkeyhash 160bit address when spent from a pubkey or pubkeyhash transaction
Coins can be sent to either contracts or pubkeyhash addresses. When coins are sent to a non-existent contract address, the coins will automatically be sent to a pubkeyhash address instead.
Only 1000 vouts can be generated from a single contract execution. Sending coins to the same contract multiple times results in a single vout being created, so the limitation is effectively that coins can only be sent to up to 1000 unique contract or pubkeyhash addresses, including balance changes between contracts. If this limit is exceeded, an Out Of Gas exception is generated and all state changes are reverted.
Contract executions can not happen within coinbase or coinstake transactions
Additional documents for the overall design and expected results of various operations is available at the ITD repository here:

If you would like to receive Test Network tokens, please PM this account with your address and we will get them sent ASAP.  These test tokens will have no value, so you are free to share them with others for testing. We will have a faucet set up shortly, along with a Win64 QT shortly

Staff members in our Slack channel will have Qtum Test Tokens to distribute. Remember, these are free and have no value.

Right now the team is preparing for our launch event in Shanghai, so it may be a touch busy on our side for the next day.

thanks for the great updates!

looking forward to the mainnet release.

Qtum is more popular than Ethereum in China.

and Qtum have more community member than Ethereum in China... Cheesy

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, everyone should read it.

that's one of the most exciting post this year.

Here's another informative post from 老人没有工作。

A big thanks to Decentral Toronto for letting the #Qtum project present May 17th! The event took place on a large boat, with about 250 attendees. Brett and Jordan were in attendance, and we gave a general overview of the technology and our crowdsale results. We weren't the only Blockchain project in attendance, there were presentations done by #Zcash, #Pivx, #Dash, #Jaxx, and #Rootstock!

Fuckin amazing that the gurus of the greatest invention since sliced bread can't even muster up over 7 likes on their Facebook page in spite of lyin' their motherfuckin asses off of having ~250 attendees listenin' to their snake oil presentation in a room having a max setting capacity of only 76 IF EVERY FUCKIN SEAT WERE OCCUPIED, of which they weren't.

If you can't do the math, then find some other person able to count to potato, then find another person who'll explain to you how you're getting royally fucked in the ass using the data supplied by the dude who can count to potato.

Now if you'll excuse me, I'm goin' on break at the job I don't have, of which I'm allow 17 breaks a day given that I'm a old man.


EDIT: Here's another pic depicting 250 people in a room designed for 76. To be fair, I did figure it out - each person had two pockets, and in each pocket was an attendee, thus Chinese math dictates that 76 X 3 = 250. Oh, and don't fuckin forget that of those 76 people, some are other speakers and their entourage.

what's your point?
oh never mind..

no one care about your point..i think..

Qtum interview, there is 9209 reads in China in one day...

Ethereum can never do this in china.....

can someone translate this into English?































但是当时众筹资金被盗了,事件发生后社区里就分为两派,一派认为既然认可Code is Law(程序即法律),那么就要接受程序会出现bug的事实,接受资金被盗的结果;而另一派人认为我们还是生活在现实世界里,所以我们要把钱追回来。于是这个网络当时就分叉了,这也反映了以太坊的一个问题,当智能合约不成熟的时候,现实世界如何在发生如上事件的时候干预这个网络。




另一个就是整个平台的安全性对区块链网络也是非常重要的,这就非常细节了。比如说一个平台要发布需要经过各方面的测试,α、β、peer review这些自动化测试,还包括你的技术选型,你所选择的技术来源是不是经过了充分测试。当时以太坊为什么出现被盗问题而比特币不会呢,因为比特币这些核心代码是全世界将近上千个开发者研究八年研究出来的,所有的bug和漏洞都修修补补好多次了。一套大型的软件系统没有bug是不可能的。





我举一个简单的例子,中国最好的房产中介公司应该是链家,它可能有一万到两万的中介,每天做的事情都是重复性的劳动。就是说有人要租房有人要出租,其实每天就是签合同。但是在区块链网络上你可以在几秒钟内创建有相同功能的角色,就是一个smart contract,它起到的作用其实跟链家的中介一模一样。我们这个合同可以在block chain的网络上直接签署。但是有一点非常不一样的就是,计算机是非常善于做重复劳动的。所以说链家的三万个中介在计算机网络上可能一天里就能创造出三万个智能合约。

区块链最大的意义就是提供了一个trust service,但是整个社会运营的根基其实就是trust。比如说大家相信银行,相信支付宝,相信微信,因为它已经做到很大的体量,你不会觉得支付宝有一天会跑。但是整个社会的产业链里面,其实很多行业是没有trust的。他们的trust是建立在人际关系上面的。


那为什么token 是有价值的,这些币为什么要涨,因为它背后没有股份。既然大家认为有一天比特币的网络、以太坊的网络会干掉BAT,会干掉链家,会占据银行的部分份额,那站在这个角度上来估值,我觉得这个行业估一千亿美金还太小了。

为什么称比特币为数字黄金?它不单是一个货币,它还提供了一个trust service。单就货币的角色它的表现属性已经远远超越黄金了。黄金就是一个元素,黄金的价值是来自于人们赋予它的价值。从价值交换的角度上来说,比特币价值来自于使用的便利性和背后大家对它的信任程度。黄金也是因为有人相信黄金有价值才有价值的。




ICO 和IPO我觉得本质上没有区别,都是公开上市。当一个项目ICO之后它其实就变成了公开交易的市场。我觉得ICO其实本质就是说从第一天起它就是一个公开上市可交易的东西。对DApp来说,它这个项目没有股权,又公开上市流通了,这些拿到钱的开发团队,只要他持续在做这个项目,它就会有价值的回馈,就会有人才进入这个行业。那这个行业就会一直往前发展。

DApp变革了商业组织的模式,把原来利益的划分现在全部拿出来分给所有的参与者。最简单的就是Qtum,当时我们发行这个网络时大概全球有二十多个国家的七千人次参与。其实后面上涨的时候应该是造就了至少五百个千万富翁。从各种意义上来说,这是大家认可的一个行业发展,认同Qtum作为未来中国的一个基础服务、区块的一个trust service供应商,或者这个平台的供应商,未来能达到这些价值,所以它里面的这些代币可能就值这么多钱。





再往上肯定就是应用层了,应用包括to B的应用和to C的应用,一旦涉及到应用就会涉及到人,所以就会涉及法律上的监管,财务上的风险管理。

再往上才是和用户的交互,目前区块链用户可以感受到的一个是钱包,一个是浏览器,开发者能感受到的是集成的开发网页。还有就是smart contract,这就是我们想做的,我们要建一个智能合约的App store,这上面不做程序只做合约,每个合约有个功能。比如第一个功能就是你可以发自己的代币,就比如一个咖啡店的老板发个优惠券,原来做这种事情需要自己开发App。但是在区块链上你会发现,开发App的这种需求全部会被削弱,所以以后大家不需要开发App服务了,可能在网络上点点键盘,想要的功能就实现了。

bitcoin talk forum is NOT the center of the earth for qtum community. this forum is only a downstream platform for second hand information to trickle down. China people, China. this coin will pump from the far east and most people here will have no idea why or what reason. but pump it will. i predict usd 100 by October

I thought this Qtum thread was long till I saw the Qtum thread in the Chinese section of this forum. It's 6-7 times longer than this thread. Take a look yourself and see. If I'm not mistaken, all the active Chinese users on this forum have commented at least once on Qtum's Chinese thread. Amazing!

exactly, the reason there are no posts on the Chinese thread is because Chinese people DO NOT use this forum...that's my point. guess your perspective is in a basement somewhere trolling this forum and not lifting your head to realize there is more to this world than BTC talk.  Grin

you are right, 99% Chinese people in crypto do not use bitcointalk....

they only use wechat.

and Qtum wechat community have about 10k people in china.

Hello, what's the difference between Elastic and SONM? Some people have told me that the differences are minimal and that practically Elastic is made up of a smaller team than SONM, is this true? I really like the concept worked, you are to be congratulated! A new thread is always welcome, good luck. Cheesy

XEL is better than golem, golem is better than Sonm..

about sonm and iex..i do not know.. maybe sonm=iex.

that's all.

Some bad news came out, Agrello just switched to Ethereum instead of using Qtum like they had previously planned because they wanted to use a better tested platform.
I wonder if this means the Qtum testnet is behind schedule?

i think some project just want some quick money...

also how many project you think china have?

that's Qtum's main target..

I think China is still the main driver of future Qtum growth but it's still disappointing to see a big project like Agrello switched from Qtum to Ethereum.  
Oddly the price of Qtum went up on Yunbi today despite this news.

lol BTCSpace you made like six posts in a row, are you reading this thread all day long?  How many Qtum did you buy?!

i think the main reason is some project only want quick money,

no matter how shit that project is, they can release an ico and raise 15M $ in few minutes, enjoy bubble time.

i did not read all these post, but i do not like some stupid people, since they never use their brain and just believe what people tell them or what media tell them.

i think people who try to create fuds before Qtum ico all brought into the Qtum ico and they made 35 times profit.

people who follow the FUDs are stupid.

Haha i think so too, if u look at stratis last year, there was alot of fud during ico and they could not raise much money. Then suddenly the price go 5x on debut and the rest is history. I am the idiot that sold everything at a loss when it drop like 50%. 

what happen to status ?

want to know more information about this.

i want to build a FUD Alliance.

Turing completeness does not make a coin magically a level higher than Bitcoin and certainly there is nothing innovative about Turing completeness.

Turin completeness is also extremely flexible - this reduces cyber security constant.  Wink

good point.

but why people pump eth?
