321  Bitcoin / Development & Technical Discussion / Re: Bitcoin Block time on: August 23, 2018, 06:23:08 AM
The reason I do this discussion is that people dont want to hear about other crypto for payment. I dont understand

Then you, merchant, payment processor or payment gateway should consider use/accept zero-confirmation, it's not too risky if it's for small payment and any explorer/nodes don't detect double-spend attempt (with sufficient fee obviously).
CPFP also help if you want to use your bitcoin immediately.

Someone with good statics knowlege could calculate how average the block time is really. So normally it should be a Gauss normal distribution with the maximum at 10 mins. But it is not, cause e.g. miners are activated or deactivated and difficulty can not react. Look how many blocks are found exactly 10 mins after the last one or even 11 or 9 min.
There is no maximum on the time between blocks, so there is no maximum at 10 minutes. The distribution time between blocks is not a normal distribution. Rather it is poisson with the true mean at ~9.7 minutes. The difficulty adjusts to make it 10 minutes, but new hardware coming online pulls the time down. Since it is poisson, the time can vary a lot, from 0 minutes to several hours, there is no maximum at 10 minutes.
The true mean for bitcoin since genesis block up to now, is ~9.4 minutes last time I calculated this divergence. How did you get 9.7?

AFAIK that was mean in few years ago. My rough calculation also show 9.4 minutes mean time.

If it's really dapp, then it means the source code is available on the blockchain (which anyone can access easily) and anyone can read/audit the code to make sure whether the dapp is scam, buggy or work as expected.

But if you don't have such knowledge, then all you can do are :
1. Check review/comment from people who've used the dapp
2. Check whether someone have review/audit the code and it's result
3. Use website such as https://dappradar.com/ which usually only list proper/not scam dapp

Interesting, multiple services in a website, even though 3 others focused on your own cryptocurrency.

But i wonder how do you pledge to protect user privacy ("Privacy Protected at ALL Costs") when there's KYC ("Simplified KYC & Instant Verifications")? It's big contradiction.
324  Bitcoin / Bitcoin Discussion / Re: Bitcoin Jesusí Is Having a Hard Time Winning Over True Believers on: August 21, 2018, 07:00:39 PM
Any sane people won't choose anything where it's influential/popular people is called Jesus, IMO this looks like a sect (no offense to anyone).

Bitcoin Cash has the best technology

Then tell us few technology that Bitcoin Cash or other cryptocurrency don't invent or use it first (besides Block Size increase obviously).

cheap and fast transactions.

Ignoring both currency exchange rate, both coins have similar fee which is 1 sat/byte. But Bitcoin use SegWit technology which make transaction size smaller which means user pay less fees, besides Bitcoin have some 2nd layer or routed payment channel such as LN which have lower fees as well.

About transaction speed, both of them are equally fast since both have 10 minutes block time and merchants can accept zero-confirmation transaction.
325  Other / Serious discussion / Re: Code of Conduct in Exchanges: The Crypto Constitution (+ Terms of Use screening) on: August 21, 2018, 06:42:43 PM
Great idea, i've few improvement/idea such as :
- clear rules about deposit/withdraw/trading limit for unverified and verified users
- transparency about user compensation if their server is breached

But frankly i'd rather push the community to use DEX (at least for crypto-to-crypto trading) and atomic swap once it's available.
326  Alternate cryptocurrencies / Altcoin Discussion / Re: Bitcoin Real (BCr)- Are they the New Bitcoin? on: August 20, 2018, 04:15:30 PM
They don't have website and their whitepaper totally show that they only steal combine few technology which already used by few other cryptocurrency and frankly it's no different from ICO's whitepaper which usually fail.

Basically : yet another bitcoin forks with existing technology as it's selling point

People are already fed up of forks and cloning of a thing to make it real.
Bitcoincash is the only surviving one because it was supported by huge names of bitcoin mining industry.
Bitcoingold started the premine scam and a few others followed to get free cash.
But people would be fooled no more.

Furthermore, even if the forks have few interesting features, people don't care and will the dump the coins which means the coins don't have strong community and fade.
327  Bitcoin / Bitcoin Discussion / Re: Will the real Satoshi Nakamoto please stand up on: August 20, 2018, 04:04:50 PM
This topic again? Frankly i don't care about Satoshi's real identity even though his works/research gave huge impact to many sectores (banking, economic, security, privacy, cryptography research, etc.).

IMO we should respect Satoshi's wish to stay anonymous, especially because i think Satoshi knew that Satoshi would have huge influence towards Bitcoin development/future which isn't Satoshi intended.
328  Economy / Speculation / Re: Bitcoin ETF Wonít Get Approved on: August 20, 2018, 03:57:13 PM
Who cares about ETF anyway. People who buy Bitcoin through ETF surely don't have access (private key/seed) to their Bitcoin and they can't even spend Bitcoin as they want, even centralized wallet is still better since you still can use it to make Bitcoin payment (even though there's lots of limitation and privacy concern).
What we really need are Bitcoin legality as currency/payment method and easier way to Buy bitcoin for anyone in smaller amount (and they actually have access to their Bitcoin, obviously).
329  Bitcoin / Development & Technical Discussion / Re: Chain analysis on: August 20, 2018, 03:14:15 PM
Does anyone know where can I get further info regarding this subject?

There are few researches that you can find easily, even though i never thoroughly read the research and mostly focused on de-anonymization :
https://papers.nips.cc/paper/6735-deanonymization-in-the-bitcoin-p2p-network.pdf
http://orbilu.uni.lu/bitstream/10993/18679/1/Ccsfp614s-biryukovATS.pdf
https://arxiv.org/ftp/arxiv/papers/1510/1510.07782.pdf
https://jonasnick.github.io/papers/thesis.pdf
https://arxiv.org/pdf/1801.07501.pdf
www.blockchainresearchnetwork.org/wp-content/uploads/2018/04/Khalilov-and-Levi-2018-A-Survey-on-Anonymity-and-Privacy-in-Bitcoin-like-.pdf

There are specific research for de-anonymization attempt for CoinJoin and mixing service, even though i couldn't find any. Besides, there are few popular chain analysis services such as https://www.chainalysis.com/.

What will be the impact of this analysis with the rise of LN, sidechains and other anonymity solutions?

Maybe more people will have privacy/anonymity (even though Bitcoin is only pseudonymous) concern and they might support on-chain anonymity & scaling solutions such as Schnorr Siganture and MAST.
330  Alternate cryptocurrencies / Mining (Altcoins) / Re: I Start Mining This Week, Any Advice Is Appreciated on: August 20, 2018, 02:52:02 PM
Aside from things that already mentioned, i've few advices for you :
1. Use overclock software to tweak GPU (voltage, memory clock, core clock, etc.) to get best performance/electricity efficiency[1]
2. Always use monitoring software to keep an eye on your CPU/GPU temperature since overheating will make it's lifespan reduced
3. If you plan to buy AMD GPU in future, you should modify it's BIOS as well to get best performance[2]
4. Use PSU with good quality. 80 Plus Gold is the minimum, unless you don't mine 24/7

Unfortunately honeyminer don't show any error/warning message. I'd suggest search for .log file from honeyminer/XMRStak so the diagnostic process would be easier.

Few suggestion :
- Check your GPU with GPU stress software to check whether your GPU is working fine.
- Check whether you can use your GPU for mining with other mining software (such as Claymore) OR Linux OS specialized for mining (such as https://simplemining.net/ and https://perfectmine.io/)
332  Alternate cryptocurrencies / Service Announcements (Altcoins) / Re: [EXCHANGE]💰ChangeNOW: anonymous | limitless | 0.5% fee 💰 on: August 19, 2018, 03:03:19 PM
Aside from problem that other user mentioned, i strongly doubt your service is really anonymous because :
1. There's no .onion URL which usually used for anonymous service
2. Your web broke if i use NoScript add-ons
3. CloudFlare protection
333  Other / Meta / Re: I wish there was somewhere to discuss new crypto projects. on: August 19, 2018, 01:11:58 PM
Why don't you make thread about your ideas on Serious discussion or Project Development since there aren't many spammer there.
334  Bitcoin / Development & Technical Discussion / Re: Smart Contracts - just a buzzword or are they applicable to the real world? on: August 19, 2018, 01:01:58 PM
Smart Contracts have real usage to the real world, however the usage is extremely limited since most task require 3rd/trusted party. Besides, most smart contract isn't user friendly.
I can't even think about Smart Contracts usage besides DEX, exchange, casino or marketplace for token/colored coins which already exist today.

But unfortunately it's being used as buzzword (along with Blockchain, AI and "decentralized") and majority users don't care about/don't plan to use Smart Contract.

Obviously this topic should be spoken in this but there is no big topics about smart contract here on this forum. If there is any discussion about solidity then it will be perfect way to make the money.

Go for the udemey to find many paid article and book to learn and understand about the solidity and smart contract mate.

Do you even understand what's OP talking about? Besides, bitcoin also have smart contract, even though it's not really "smart" compared to other cryptocurrency since Bitcoin script isn't turing complete.
335  Economy / Service Announcements / Re: BitMaximum.io - More privacy during Bitcoin exchange / Coin mixer on: August 18, 2018, 07:06:14 PM
Hi, i check your services and have few question/thoughts :
1. Any plans to use Schnorr Signature which improve user privacy when it's added to Bitcoin?
2. Do you have PGP/GPG key to contact you securely?
3. Do you support deposit from/withdraw to Bech32 address?

Anonymous coins are good. But, unfortunately, not everywhere I accept them as payment. Therefore, it is often necessary to use coins bitcoin. These transactions leave traces. So we have to use such services as this cryptomixer.
BTC->exchanger->Monero, ZCash, Dash ...->exchanger->BTC. w/o risk (if a reliable exchanger)
why not?

When you use the private exchangers and exchanges, you put yourself at risk. Deanonimization is maximum!

Not if you use decentralized exchange with secure connection.

7) other "anonymous" cryptocurrencies showed errors in their work during deep analysis. They also had various vulnerabilities (e.g.
as it was before in Monero). We are constantly reading and studying our colleagues, Blockchain researchers and leading specialists of various
Universities of the world, we are in the "epicenter of the Blockchain", visit Conferences, Valleys, and watch what is safe, and dont safe.

I strongly agree, but most privacy/anonymous cryptocurrency is a joke. They make privacy features optional which makes everyone can be deanonymized easily, few of them isn't private at all (such as Verge and DeepOnion which show all transaction information just like Bitcoin).


Cool Monero, dash, ZCash not convenient for everyday use. They are not fully popularized.

I agree, however there are few services which let users make Bitcoin (or any popular cryptocurrency) payment with their own private cryptocurrency such as https://xmr.to/ which preserve user's privacy to some degree while enjoy the benefit of popularity of major cryptocurrency.
IMO this gives users more privacy/anonymity compared to any mixer.

Security Depends on Choosing a Good Private Key
Knowledge of a private key is the only verification needed to spend an electronic coin. Private keys should therefore be kept secret. However, careless selection of a private key can lead to theft just as easily as its accidental release

337  Bitcoin / Development & Technical Discussion / Re: Trying to convert 256 bit random number to WIF on: August 17, 2018, 07:36:24 PM
Maybe you already try this, but have you open Bitcoin GitHub and check this file https://github.com/bitcoin/bitcoin/blob/master/src/base58.cpp? It contains both encode/decode Base58 even though it's written in C++.
If you post your code, i'm sure developer/contributor in here can solve the problem easily.
338  Bitcoin / Development & Technical Discussion / Re: Is blockchain really needed for security? on: August 17, 2018, 07:25:09 PM
For decentralized/trustless distributed database, blockchain is good solution. But there's other technology such as DAG, BitTorrent Protocol and technology that IPFS use, even though there are more cons than pros in this case IMO.
However the consensus method/P2P protocol is the one which makes blockchain is secure/immutable.

So, blockchain isn't really needed for security, even though it's good option for decentralized/trustless distributed database.
339  Economy / Service Announcements / Re: [ANN] Alagoria.com - Buy anything on Amazon for 10% Off Using Crypto on: August 17, 2018, 07:09:45 PM
Looks like interesting service and there aren't much competitor these days, but i've few question/concern :
1. Any plans to support other Amazon's country such as UK or JP?
2. About user's personal information such as shipping address, does the seller of the gift or only Alagoria who keep the information?
3. Any plan to support other popular Cryptocurrency such as Monero and Ethereum?

I would try your service if there's good feedback from reputable member Smiley
340  Other / Ivory Tower / Re: I would like to hear your opinion about Ethereum Classic on: August 17, 2018, 09:47:06 AM
ETC will never surpass ETH in both market cap, development/technology and community. Looking for long term investment or technology advancement, ETH is the winner and people don't have reason to use ETC.
But if ETC have more developers (or adopt most ETH technology), ETC would be great investment/cryptocurrency.

Its trend is a bit different from the other alts, today it's like 20% up.

This is the reason https://blog.coinbase.com/adding-ethereum-classic-support-to-coinbase-becb9a337e9c

Also, vitalik is having delusional ideas about bch, which I consider a bad sign:
https://cryptovest.com/news/vitalik-buterin-envisions-usage-of-bitcoin-cash-bch-at-convenience-store/

His vision about BCH is big contradiction since he strongly support 2nd-layer as scaling solution for ETH while BCH is the opposite.
