can someone explain to me the PoS consensus protocol didnt find much info on it, thanks!

Jake posted this awesome Qtum analysis in slack, I thought I would share..

QTUM is flying today!! glad to see this coin moving. Great tech.


Quick question does anyone know how to run the PoS for QTUM?

[hope-crypto]

nice to see there are some ICO project that will build on Qtum platform:

Energo
Inkchain
Vevue
Bodhi

Some of them have even done a crowdsale. There are about 10 projects in total that we are aware of, most of them originating in China. And I have joined in the Energo, Bodhi crowdsale,and it seems to be very hot.

They announced in slack that there are 17 projects total so far and some are waiting to announce i guess.  I'm just wondering what happened with Qtum and Tron? First it was rumored that Tron was building on Qtum, and then they were partners, and now it's unclear if there is any involvement?

Ufff really good news Qtum should doubled in September... Big news and chart is looking really good... Could go 600k +

Qtum Development Updates:


Development Updates
Bugs fixed:

[RPC] Fixed a bug where `getaccountinfo` would return a backward hex address
[Consensus/MPoS] Fixed a consensus bug with MPoS where rewards were calculated to include contract refunds, causing a pre-release version of testnet-2 to become stuck
[Consensus/AAL] Fixed a consensus bug where a malicious staker could bypass the AAL and spend funds that belong to contracts. This was the reason for the v1.1 release of testnet-2. The cause was that OP_SPEND was not actually mandatory, and furthermore by not including OP_SPEND in vin[0].scriptSig, a bypass in AAL consensus rules was possible.
[Staker] Fixed a bug where the staker could behave improperly sometimes when reverting contract state, resulting in the chain becoming stuck

Work completed:
[GUI] Added a very early UI for smart contracts, allowing you to use smart contracts within the Qtum-Qt; also reworked the layout of the GUI
[Tests] Added several RPC tests for DGP
[Tests] Added an RPC test to validate PoS segwit blocks
[Tests] Fixed some failing tests
[Tests] Added RPC tests to ensure contracts can be created within contracts, but also that contracts created with an initial endowment results in an error
[Misc] Fixed `-testnet` mode to properly function with adjusting PoS difficulty, similar to mainnet mode
[Staker] Optimized the staker by caching stake information instead of pulling it from disk every time, resulting in a significant increase in performance, especially when the wallet contains a large number of UTXOs

Great job, I have never see an ICO project announced their development progress with so much detail information, which makes me so optimistic for this project.

Qtum is one of the best project.

i think their target is Ethereum..

seems bitcointalk is dead now.

[hope-crypto]

where ca i store my QTUM if i dont want to have them on an exchange ?

I think right now they are doing their own wallet but I am not sure... Maybe look at MyEtherWallet if you could store there, but I think not...

[BitcoinExpart]

I just heard Qtum will be listed on a Korean exchange tomorrow. Can anyone confirm me about? Usually the effect should be on listing a new exchange like its demand increased so does it's price. So, QTUM a good choice to buy for some reason.

I mean it could pump or dump, but I think it will go up... Some guys are talking about ghost month and that some Asians don't buy at this time, but I think that it's bullshit...

It's supposed to be announced on Coinone exchange which is a top 5 exchange.  They're like the coinbase of Korea, and only deal with BTC, ETH, XRP (+ETC & BCC by default).  To list Qtum as the 6th would be saying alot given how relatively new this coin is.  If it does happen, you can probably expect at least 3x the price like Monero.  According to the team, they have another big exchange to announce also next month for mainnet and alot of people are speculating on a Kraken or Polo listing.

Ghost month has been proven to be FUD. BiteSizeBitcoin made a good video about it showing it to be wrong. I think September will be an overall Bullish month on all cryptos. Hopefully I am right about that.

I think Qtum has a lot of scope. But its competition is one tough competition. I am hoping that Alibaba comes through with Qtum as I believe they are working on a project together. Anyone know of any updates on that project?

Qtum Community & Development Updates — August 28

https://medium.com/@Qtum/qtum-community-development-updates-august-28-b8e87411753


Main Network Launches September 13th, 2017


The Qtum Team would like to officially announce the release of our Main Network for September 13th. This will take place right before Wanxiang’s Blockchain Conference. Qtum’s Mainnet will be the follow up to our ‘Skynet’ release earlier in August. Qtum will feature the functionality found in Skynet, like the Decentralized Governance Protocol, EVM on UTXO, Proof-of-Stake Consensus, and mobile smart contract functionality.

This is a major milestone for the Qtum project, as this is a group of blockchain enthusiasts turning a dream into reality. Making this happen would not be possible without the 18 months of hard work that went into this from our 30+ team members. This is just the start of what we have coming. Qtum’s development plans requires many years to fulfill, so keep an eye on our road map in the months to come.

For those of you who have been following the project since early 2017, you know we fought a hard battle to get here, so thank you for the support.
There will be a launch event in Shanghai on the 13th, seating is extremely limited, but we will do our best to live steam it around the world. Please keep in mind that the state of high speed internet in China is a huge challenge, so we may have to release a recorded version after.

Updated Development Roadmap

Development Updates:

Releases:

Skynet testnet-2 v1.2 was released — A mandatory update that fixes several minor consensus bugs and some major staking/block creation bugs

https://github.com/qtumproject/qtum/releases/


Bugs fixed:
[Consensus/AAL] Fixed a bug where 2 successive contract transactions that caused 2 successive OP_SPEND transactions would not be allowed
[Consensus/EVM] Fixed a bug where block.difficulty in the EVM would give incorrect results
[Consensus] Added several new rules to check the size of various fields in contract transactions and properly reject poorly formatted transactions
[Consensus] Added several overflow checks for gasLimit, gasPrice, and gasLimit multiplied by gasPrice
[Consensus] Fixed some contract parameter parsing code to not rely on unintialized variables, causing undefined behavior
[Staker/EVM] Fixed a bug where a contract execution would see different block times than at validation, producing broken blocks in the staker


Work completed:


[GUI] Fixed several minor issue with the smart contract GUI
[Misc] Setup an actual `-testnet` mode for Skynet testnet-2
[Staker] Added some undocumented command line arguments to make the staker work in various emergency conditions
[Build] Fix a minor compiler warning for the new GUI changes
[AAL] Added several new error messages to aid in debugging
[Consensus] Change several consensus rules from asserts to DoS errors, so that they can not be used to shut down a node
[Misc] Bumped the version of the Skynet wallet to v0.14.2
[Consensus/Misc] Qtum now tracks the coin supply of the blockchain, and implements a sanity check to ensure that more coins are not minted than expected

Great update. Sky's the limit
