Topic: [ANN] (QTUM) - A Scalable Smart Contract Platform w/ Proof of Stake - page 224. (Read 525530 times)

If you use 2 of 3 multi-key, it means no escrow in this project, and the fund can be transferred by only 2 co-founders, how about 2 are corrupted? The fiasco will happen if that happens. I prefer seeing a 4 of 5, and two escrows involvement can prevent corrupt and collusion.

What day did you first learn about Bitcoin? I mean, I officially say I started programming when I was 13, but I can't remember exactly that long ago. I may have been 11 or 12, or I could have been 14. It can be hard to remember which year when it was many years ago, but anyway, relevance?

Qtum good or Qtum bad So many questions after publishing this impartial facts about devs team. Suppose that if some innovative nature of the project is confirmed in the future it will be possible to buy coins on the exchange.

You're having a hard time addressing concerns sans sticking it up my ass, eh?

In re the following: Nuance?

how Qtum be compatible with Ethereum platform?

(from: https://qtum.org/en/lm/account-abstraction-layer-overview)



Building on bitcoins reliable and proven-to-deliver blockchain, Qtum stacks its Account Abstraction Layer, allowing the Bitcoin Core 0.13 blockchain to seamlessly interact with the Ethereum Virtual Machine (EVM). With this innovation it is now possible to execute smart contracts and run decentralized applications, simply and securely, in environments that were previously out of reach for Ethereum, combining the endless possibilities provided by smart contracts with the stability and maturity of the bitcoin ecosystem.

Until now, attempts to implement smart contract solutions on top of the bitcoin blockchain have had issues, been lackluster, or failed to break into the mainstream business market. This is primarily due to the fact that the bitcoin blockchain employs an Unspent Transaction Output (UTXO) scheme to associate coins with addresses, rather than the easier to understand, but otherwise problematic, account-based model used by Ethereum.

An account based model works pretty much the way one would imagine:  if Alice has 10 tokens, and sends 5 of them to Bob, who has zero tokens; 5 tokens are simply subtracted from Alice’s balance and added to Bob’s, who now owns 5 coins.  On a UTXO blockchain, however, Alice does not directly hold 10 tokens, but a series of outputs, which are collections of coins resulting from previous transactions.

In such a model, instead of owning 10 tokens, Alice would, for example, hold 3 outputs: (a) consisting of 6 coins, (b) consisting of 2 coins, and (c) consisting of another 2 coins. In this scenario Alice couldn’t simply send 5 coins to Bob, but instead she (or her wallet, for that matter) would have to pick the best-suited output and receive “change” in return (a process called coin picking). In our example this means that Alice would transfer output (a), consisting of 6 coins, and receive 1 coin back as “change”. This “change” is what is called the Unspent Transaction Output, or UTXO. After the transaction Alice would still hold 3 outputs, this time (a) consisting of 1, while (b) and (c) remain 2.

Employing such a seemingly complex bookkeeping scheme allows the Bitcoin blockchain to support Simple Payment Verifications or SPVs. The SPV protocol enables the support of light wallets, which are wallets that can interact with the Bitcoin network in a decentralized and trustless manner, without having to download the entire Bitcoin blockchain. This property is immensely useful for mobile applications or in any low bandwidth/storage environment.

Until now, Ethereum smart contracts couldn't execute in such environments exactly because Ethereum’s account based blockchain does not provide a SPV analog. To solve this, Qtum builds its decentralized application platform on the proven-to-deliver Bitcoin blockchain and introduces the Qtum Account Abstract Layer, which serves as a communication layer between the Bitcoin Core 0.13 protocol and the EVM.

To achieve this, Qtum has extended the Bitcoin 'Script' language, adding 3 ‘opcodes’ so that it functions as a vehicle to transport code to the EVM, while adding special processing conditions, executing these EVM-using transactions immediately when added to the blockchain - allowing the EVM to operate within a UTXO environment.

In order to relieve Qtum smart contracts from the need to perform coin picking for every transaction, Qtum comes coded with an automated, generic coin picking algorithm which allows contracts to ignore the UTXO mode of operation, while functioning normally, as if deployed in an account-based environment. This method is what enables Qtum to be compatible with pre-existing Ethereum smart contracts, allowing them to be executed on Qtum with little to no change to their code.

For more information about Qtum’s architecture in general, please read this post or review our  Technical Whitepaper.

It seems you found a news article translated from Chinese to English that apparently didn't keep that nuance. That makes Patrick a scammer... how? Patrick has been pretty public about being a PhD drop out, though I believe he wants to go back to school sometime later when he's less busy to finish his PhD.

Here's something interesting:

I support you so that scamer can not do this kind of fraudonly a fool would invest in this project

dai....dai...dai....dai....daiii....

I just realized what I'm doin' w'ong. My questions r 2 complex. I must use smaller sentences.

Earlz, see 2 pics? Why different info?

Give it up, Gleb! QTUM is happening! Sheeps will be slaughtered! They have the finances to drown out your voice. Let's just pump and dump this shit.

Note to self: Co-founders of entities looking to garner $10M in ICO funding are allowed to call posters in their threads "Sherlock" in lieu of addressing serious accusations. That said, I'll try again.

Earlz, co-founder of Qtum, please explain why all the initial bitcoins that were transferred to Qtum's bitcoin wallet address stemmed from addresses formally used by TileCoin, when Patrick Dai was with them, via BTER, once hacked under Patrick's associates' watch, then later most were transferred to Star Xu's OKCoin prior to Star Xu acting as one of the Angel seed investors in funding Qtum?

TBC, I have every intention of bumping this thread with such questions each and every time cocksuckeroverflow posts his bullshit.

FWIW, I used to be a professional bear wrestler:



Yes, that's a 700 pound bear named Ginger.

I'd think a Sherlock like you can find trivial details like this when they're on our OP and website

Excellent! Now that's it's established that you're a co-founder of Qtum, all questions and concerns can be provided by you.

The exact number of keys is not yet determined, but the 3 co-founders (me, Patrick, Neil) will own a key (so at least 2 of 3, but we are discussing 3 of 4)

"Blockchain technology has a wide range of potential applications,” said BitSE CEO Qian Dejun. “More clients will focus on blockchain and start to adopt it in their industries in the near future. PwC has extensive expertise and advisory experience, which will help us to promote these new solutions in the market."

Remember Black Arrow?: http://www.blackarrowsoftware.com/download/chengdu_contract.pdf

I read your whitepaper, the QTUM foundation is very promising organization, do you have escrow in this project? 3 co-founders have the same amount of shares or Patrick is largest shareholder?

On the front page of the Fintech section of IBTimes to boot!

Try not interrupting me, cocksuckeroverflow, while I'm penning Qtum's web of deceit.

Now that's some good press!
