terima kasih infonya gan, kalau boleh menambahi, yang paling penting menurut ane adalah berapa fee nya? dan berapa lama kira-kira lama koin tersebut untuk sampai, karena penting dan perlu diingat bahwa harga di trading selalu berubah ubah setiap detiknya, jadi harus memilah dan memilih mencari platform dan koin yang bagus, murah dan cepat, agar meminimalisir terjadinya harga turun saat koin sampai di paltform yang dituju.

beda coin beda fee , beda exchanger beda juga respon payment gateway.
jadi paling tidak punya pengalaman dari beberapa exchanger sebelum melakukan arbitrase.

Overwinter Ahead: What Should Happen When Zcash's First Hard Fork Hits

Privacy-oriented cryptocurrency zcash is about to undergo its first-ever hard fork.

Called "Overwinter," the update requires all users of the nearly $800 million blockchain to switch to a new software. But while these kinds of system-wide changes can be high-risk – if some users reject the change, it can split the blockchain and create a rival cryptocurrency – zcash developers are saying there might not be anything to worry about with this particular update.

Set to activate at block number 347,500, which according to current block times, will happen early on Tuesday morning, Overwinter is being described as a low-impact intermediary step, one that prepares the network for another upgrade in October that has broad support.

That's because the next hard fork upgrade, called Sapling, is all about eliminating the weight of the protocol's private transaction types so that zcash can scale to more users. Essentially, there isn't expected to be much dissent as Overwinter aims to improve on a core attribute of the code already.

According to the zcash website, a total of 12 exchanges, mining pools and startups have come forward to support Overwinter, while further parties – MinerGate, Bitfly and Huobi – have publicized support on Twitter.

As such, Simon Liu, an engineer at zcash, said he does not anticipate risks in the rollout.

"There is unanimous support from all parties," Liu told CoinDesk.

And the cryptocurrency's creator, Zooko Wilcox, echoed this confidence in interview with CoinDesk.

"We've been working with a whole bunch of industry partners and they are all on board with the rollout program," Wilcox said, adding:

"Basically the entire company almost is dedicated to executing [the upgrade] safely and smoothly in order to increase security for all users."

That said, the run-up to the hard fork hasn't been without its drama.

D. Jane Mercer, the developer of the zcash Windows wallet, WinZEC, threatened to stop contributing to the wallet's code and a chain split on June 20 if he didn't get further funding to support his work. However, the situation was resolved quickly, with anonymous donations pouring into the developer.

At the same time, disenfranchisement within the zcash mining community, still grappling with the introduction of an ASIC for zcash mining has continued to build.

However, developers are confident that this is unlikely to impact Overwinter given the nature of the upgrade.

Simple changes
One of the reasons for zcash developer's optimism about the Overwinter hard fork is that those backing the protocol have taken various steps to make sure everything goes smoothly.

For example, the upgrade is low on features, said zcash engineer Jack Grigg. Primarily, it's designed to prepare the network for its October upgrade, Sapling, by adding features that protect the network during system-wide upgrades.

Aside from that, Grigg said, the only code changes are useful optimizations – such as a new form of transaction expiry, that cancels payments if they aren't processed after a certain period of time, and the removal of a hashing bug that makes certain transactions heavier.

Speaking of the latter, Grigg said, "There is good incentive for the network to support it in order to improve performance for transparent transactions with many inputs," adding that because of that the risk of a contentious chain split is low.

That said, there are still inherent risks involved.

Because several features have been added that look to protect users from any harm that can come from future chain splits – like so-called "replay protection" – those features don't exist now and so could cause problems should a chain split occur during Overwinter.

Speaking to this, Grigg told CoinDesk:

"The Overwinter network upgrade is specifically intended to make future network upgrades safer, so by definition there is more risk during its rollout than for future network upgrades, since some of the features it introduces can't be leveraged for itself."

Vietnam’s Ministry of Finance has officially proposed that the country bans the import of cryptocurrency mining equipment. Bitcoin mining rigs are currently easily imported into Vietnam. This proposal follows the largest crypto fraud case in the country involving over $656 million and more than 32,000 victims.

Ministry of Finance’s Proposal

In the recently released report containing the opinions of the ministries involved in the management of bitcoin and other cryptocurrencies in Vietnam, the country’s Ministry of Finance proposes suspending the importation of mining equipment, according to local media. This report, referred to as Document 5964 / BTC-TCHQ, has been submitted to the country’s prime minister. Zing.vn publication elaborated:

According to the Ministry of Finance, mining machines are not on the list of goods banned from importation and are not subject to the list of specialized management or unsafe goods, so enterprises are easily allowed to complete the import procedures.

The ministry outlined in its report that the use of mining equipment for bitcoin, litecoin and other cryptocurrencies in the country is difficult for the authority to manage. “From there, it is easy for people to use [cryptocurrencies] as a currency or another method of payment,” the City Economic News Kinhte & Dothi quoted the ministry. “This is in violation of the amended government Decree 101 on non-cash payments,” Zing.vn conveyed.

The publication also noted that data from the General Department of Vietnam Customs shows that “from 2017 to half of 4/2018, the country imported about 15,600 mining machines,” adding that most of them were imported into Hanoi, Ho Chi Minh City, and Da Nang. Last year, more than 9,300 rigs were imported into Vietnam and over 6,300 rigs were imported in the first four months of this year.

Vanitygen is a command-line vanity bitcoin address generator.

If you're tired of the random, cryptic addresses generated by regular bitcoin clients, you can use vanitygen to create a more personalized address.  Add unique flair when you tell people to send bitcoins to 1stDownqyMHHqnDPRSfiZ5GXJ8Gk9dbjL.  Alternatively, vanitygen can be used to generate random addresses offline.

Vanitygen accepts as input a pattern, or list of patterns to search for, and produces a list of addresses and private keys.  Vanitygen's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky.

The example below illustrates a session of vanitygen.  It is typical, and took about 10 sec to finish, using my Core 2 Duo E6600 CPU on x86-64 Linux:

$ ./vanitygen 1Boat
Difficulty: 4476342
Pattern: 1Boat                                                                
Address: 1BoatSLRHtKNngkdXEeobR76b53LETtpyT
Privkey: 5J4XJRyLVgzbXEgh8VNi4qovLzxRftzMd8a18KkdXv4EqAwX3tS

Vanitygen includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen).  Both can be built from source, and both are included in the Windows binary package.  Also included is oclvanityminer, the vanity address mining client.  Oclvanityminer can be used to automatically claim bounties on sites such as ThePiachu's vanity pool.

Current version: 0.22

FAQ

What types of patterns can vanitygen search for?

Vanitygen can search for simple prefixes or regular expression matches.

Prefixes are exact strings that must appear at the beginning of the address.  When searching for prefixes, vanitygen will ensure that the prefix is possible, and will provide a difficulty estimate.  Exact prefixes are case-sensitive by default, but may be searched case-insensitively using the -i option.

Prefixes are also very fast to search, and a list of thousands of prefixes may be specified with little or no reduction in key search rate.

Regular expressions are programmable pattern filters.  They are very powerful, and can be used to match prefixes, suffixes, varying-length sequences, etc..  For a quick tutorial, see http://www.regular-expressions.info/quickstart.html.  To enable regular expressions, use the -r command line option.  Unfortunately, regular expressions are very slow, and will have a significant impact on key search rate.  Because of this, regular expressions should only be used if their expressive power is needed.

Oclvanitygen is only effective at searching for prefixes.  Regular expressions will not work effectively with oclvanitygen, as oclvanitygen is currently unable to execute the regular expression on the GPU.

How do I specify a list of patterns?

Vanitygen can accept a list of patterns to search for, either on the command line, or from a file or stdin using the -f option.  File sources should have one pattern per line.

Upon finding a match for a given pattern, vanitygen will stop searching for additional matches for that pattern.  To search for multiple matches for each pattern, use the -k option.

How do I import the private key into bitcoin?

If you wish to spend coins received on a vanity address created by vanitygen, you must import the private key into a bitcoin client.  There are two popular methods of doing this with the standard Satoshi bitcoin client:

• Use the importprivkey command.  To do this, select Help -> Debug Window, and in the window, on the bottom line, enter importprivkey <privatekey>, e.g.

importprivkey 5J4XJRyLVgzbXEgh8VNi4qovLzxRftzMd8a18KkdXv4EqAwX3tS

• Jackjack's pywallet script is an all-in-one tool that directly modifies the wallet.dat file.  This works with a normal, unpatched bitcoin client, but does require Python with the bsddb package.

If I stop vanitygen when it reports 60% complete, how do I have it restart where it left off?

You don't need to.  The percentage displayed just shows how probable it is that a match would be found in the session so far.  If it finds your address with 5% on the display, you are extremely lucky.  If it finds your address with 92% on the display, you are unlucky.  If you stop vanitygen with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky.

When I double-click on vanitygen, a black window appears for a split-second and disappears, what do I do?

Currently, vanitygen only runs on the command line, and does not have a graphical user interface.  To use vanitygen, you need to open a command line window and change to the directory where you extracted the vanitygen program.  An easy way to do this in Windows 7, hold down the shift key, right-click on the folder where you unzipped vanitygen, and select "Open command window here."  Then, you can type the vanitygen command at the prompt.

Can I use vanitygen to find someone else's private key from their bitcoin address?

Yes.  Vanitygen is a cryptographic brute-forcing application, and can be used to search for a complete address.  However, you will be unhappy with the amount of time required for it to find a match.

How do I report a bug?  What do I do if it crashes?

Post to this thread, send me a PM, or send me an email!  Please run vanitygen with the -v flag for verbose output, and please include the console output in your report.

How do I build vanitygen from source?

Please refer to the file INSTALL in the source distribution.

What key search rate can I expect from hardware X?

Detailed list forthcoming.  Some ballpark estimates are listed below.

Dual-core desktop CPUs, 32-bit mode: 100-250 Kkey/s.
Dual-core desktop CPUs, 64-bit mode: 150-450 Kkey/s.
Quad-core desktop CPUs, 32-bit mode: 200-400 Kkey/s.
Quad-core desktop CPUs, 64-bit mode: 300-750 Kkey/s.

As vanitygen performs a lot of large integer arithmetic, running it in 64-bit mode makes a huge difference in key search rate, easily a 50% improvement over 32-bit mode.  If you are using a 64-bit edition of Windows, and not using a GPU, be sure to use vanitygen64.exe.

In custom builds, CPU performance will be less than expected if the OpenSSL library is an older version (<1.0.0d) or is not built with the appropriate optimizations enabled.

General formulas for expected performance on GPUs

NVIDIA GeForce 96xx, 98xx, GT 1xx, GT 2xx, GTX 2xx (G90/GT200):
Key/s = (CUDA Cores) x (Shader MHz) x 17

AMD Radeon 58xx, 59xx, 67xx, 68xx (VLIW5):
Key/s = (Stream Processors) x (Core MHz) x 20.1

AMD Radeon 69xx (VLIW4):
Key/s = (Stream Processors) x (Core MHz) x 13.6

AMD GCN, NVIDIA Fermi/Kepler: Please contribute some numbers!

Unfortunately, AMD VLIW4 does not perform as well as VLIW5 with the same number of cores/clocks.  Oclvanitygen is sensitive to integer multiply throughput, and VLIW5 can multiply concurrently with other operations, whereas multiply consumes all four ALUs in VLIW4.  At similar clocks, a hobbled Radeon 5830 will outperform a Radeon 6970.

I have a lot of compute power, and want to make vanity addresses for others.  How do I do it?

The difficulty with this is convincing your customer that, once you provide them with a vanity address, you do not have a copy of their private key.  Some methods of doing this have been discussed on the forum, and vanitygen currently supports one of them.  To generate an address securely, your customer generates a private key, and provides you with the public key part.  You use this public key as part of the address search, and when you find a match, you provide them with a partial private key.  The customer then adds the partial private key to their private key to get the vanity address.  Because the customer never disclosed their part of the private key, only they have access to the complete private key.

There are many ways to get a key pair, but to do address-for-hire, you need the complete public key in hexadecimal format.  The bitcoin address is not sufficient.  One way to generate one and get this is to use the keyconv utility, keyconv -G, and get the following parts:

$ ./keyconv -G
Pubkey (hex): 041d2e778ae6d9124736df131cd22d3a2483f336c55156d87a84c4bdc6d89f8518e33de85ae0f907a7128c476281bc8cc7742b43a54ccc2c7824dc4c4a438a7fbc
Privkey (hex): 61E00B1C57E7F0D508C7C3795F90C0ACEC1DCAF6A7B82C951D23F728FD53E4BE
Address: 15wRE5VA5uhxs5o6LayZC6imES2SeZeXd4
Privkey: 5JZPftgcsaG5Unp24cf47zP7JZEZkfnSAZzefezAVNRomKHZE8f
The customer saves the privkey part in a secure location, and provides you with the Pubkey (hex) part.

Then, you run vanitygen or oclvanitygen, and specify the customer's public key:

$ ./vanitygen -P 041d2e778ae6d9124736df131cd22d3a2483f336c55156d87a84c4bdc6d89f8518e33de85ae0f907a7128c476281bc8cc7742b43a54ccc2c7824dc4c4a438a7fbc 1Boat
Difficulty: 4476342
Pattern: 1Boat                                                                
Address: 1BoatWxEHyVXkjS78d16LMuj8YMdZ1Kce8
PrivkeyPart: 5KCwog8Ndt64ZicNSGoDBRf4vACBptM2GUtSJCmkbqpieC8idcP
Because a public key was specified, vanitygen now provides a PrivkeyPart rather than a Privkey result, which is useful only to your customer.  The customer then takes the partial private key produced by vanitygen and adds it to their private key.  This can be done using ThePiachu's handy website, or using the keyconv utility:

$ ./keyconv -c 5JZPftgcsaG5Unp24cf47zP7JZEZkfnSAZzefezAVNRomKHZE8f 5KCwog8Ndt64ZicNSGoDBRf4vACBptM2GUtSJCmkbqpieC8idcP
Address: 1BoatWxEHyVXkjS78d16LMuj8YMdZ1Kce8
Privkey: 5J1Jieusaa6vegTQZ7PNG3hMcsM2FjgHPK1BkPjbYyQsWb9k5vj
Here, keyconv is able to recreate the final address found by vanitygen, based on the two private key parts.  It is also able to create the final private key.  This is infeasible for someone who does not have both parts of the private key, and provides your customer with real security.

This process is very complicated.  A simpler way to do it is to use a bounty pool such as vanity pool.

How do I participate in vanity pool?

To do this, use the oclvanityminer program.  Oclvanityminer works much like a familiar bitcoin miner.  It connects to a bounty server, downloads a list of bounties, automatically chooses one, searches for a match, and submits the results back to the server when one is found.  Oclvanityminer periodically reconnects to the bounty server to check if bounties have been claimed, or more profitable bounties have been posted.  An example session:

$ ./oclvanityminer -u https://vanitypool.appspot.com/ -a 1samr7UZxtC6MEAFHqr1h3Kq453xJJbe4
Searching for pattern: "1satoshi" Reward: 0.100000 Value: 0.000007 BTC/MkeyHr
Difficulty: 51529903411245
Searching for pattern: "1Satoshi" Reward: 0.100000 Value: 0.000007 BTC/MkeyHr
Next match difficulty: 25764951705622 (2 prefixes)
[6.14 Mkey/s][total 62914560][Prob 0.0%][50% in 33.6d]

Note that vanitypool and oclvanityminer are currently under development.

How secure are the addresses generated by this program?  Will someone be able to guess the private key and steal my BTC?

Vanitygen uses the OpenSSL random number generator.  This is the same RNG used by bitcoin and a good number of HTTPS servers.  It is regarded as well-scrutinized.  On Linux, the RNG will be seeded from /dev/urandom.  Guessing the private key of an address found by vanitygen will be no easier than guessing a private key created by bitcoin itself.  Nonetheless, if you feel the default RNG is unable to provide numbers that are sufficiently difficult to guess, vanitygen can be directed to seed the RNG from an external file using the -s option.

To speed up address generation, vanitygen uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match.  As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG.  Vanitygen will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for.

What security measures should I take?

• Secure any systems used to generate addresses.  Don't run web browsers on them.  Keep malware and unauthorized individuals out.
• Ensure that any private keys reported by vanitygen are stored and transmitted securely.
• The command line method of importing private keys into bitcoin requires you to enter your private key on the command line.  Bitcoin takes a long time to perform an import, and while it is running, your private key will be visible in the output of "ps," so be careful!  Also, the private key may be leaked to your shell history file.  Kill your shell and shred your shell history file after importing.

What are the other methods of generating vanity addresses?

The original method of generating vanity addresses is a patch to the official bitcoin client created by Gavin Andresen.  Details can be found here.

Forum user Nyhm created an in-browser vanity address generator.

There is a new vanity address generator for Android.

How perhaps the most controversial country in the world like China has banned BTC? Their flag is red communist and we often see news about Chinese workforce, the censorship, the state-run business, the lack of freedom to protest and rally, the constant pressure that is the Chinese society and most recently, the cameras everywhere watching your life everytime as you leave home (at least in the big urban areas). At the same time, China is the world's strongest economy, truly the biggest force in the capitalist world, strong investor and voracious land buyer, China is the world factory.
One of BTC biggest believers and investors are Chinese, there are many chinese enterpreuners with a very capitalist mindset (different from what you would expect from a communist country) and I believe the a good portion of cryptocurrency users in Asia are Chinese, so... Why? It has to do with elections, ideology and communists. The left-leaning voters have no trust in "foreigner things" and the current president in order to guarantee his position, he needs their loyal support and by banning BTC trades hes appealing to his Communist voting bloc.
So in the following years BTC will come back at full strenght in China, even though I dislike the chinese president he has done many good things for the international market and the capitalist world.

What do you guys think? Do you think maybe other leftist countries will follow Chinese example?
