I've tried http://plagiarisma.net/ and i can agree with it have better method, but sometimes the result is too sensitive, especially if it contains common words.

Additionally, it has limited check amount for free user and doesn't use HTTPS which is concern for Tor user like me.

As a result of numerous trials and error, we found the most ideal way to deal with multiple accounts and abusing faucet - adding PLAY MONEY currency and the ability to use faucet after first deposit.



Nice decision, even though IMO other options such as enable withdraw after first deposit or high minimum withdraw, so abuser will lose their money from faucet before reach minimum withdraw.

Still, it's more effective than block user who use VPN, Proxy or Tor because privacy/security concern, not abusing faucet/break other rules.

--snip for clearer thread--

Long requested and finally here! Already seeing Doge highrollers!

very nice primedice added doge,I always play with doge.

but, I think, the minimum withdrawal of 4000 DOGE is very large  Grin

I agree. DOGE faucet only give 0.1 DOGE and i doubt anyone could make even 1000x profit from faucet only. But 4000 DOGE equal to $20 which is small amount for gambling.

Hanya sekedar konfirmasi saja, klo salah mohon dikoreksi  Cheesy

2. Node mengirim/broadcast transaksi ke node lainnya dalam satu sirkuit.

Pada fase stem transaksi (message) diteruskan ke node selanjutnya secara acak (dari 1 node ke 1 node lainnya)

Quote
3. Node selanjutnya (yang menerima transaksi) secara acak menentukan :
   A. Mengirim/broadcast transaksi ke bitcoin network (kemungkinan 10% pada umumnya)
   B. Hanya Mengirim/broadcast transaksi ke node selanjutanya di dalam sirkuit tersebut (kembali ke step 3)


Pada fase fluff, node yang menerima transaksi (message) tersebut selanjutnya akan menyebarkan message tersebut ke node-node lainnya menggunakan protocol diffusion.

Ref : https://arxiv.org/pdf/1701.04439.pdf


Berdasarkan yang saya tau, itu sudah benar. Tetapi saya sengaja tidak memberikan detail seperti stem phase, fluff phase/mechanism, dan saran untuk memilik 2 node dandelion permanen dari node/peer list karena saya bertujuan memberikan info secara umum yang mudah dipahami.

1. Pada fase terakhir "fase fluff" apakah memungkinkan broadcast transaksi memiliki jumlah yang sama dan waktu transaksi yang sama? Lalu bagaimana jika ada creator protokol baru yang berhasil memecahkan protokol Dandelion berdasarkan kecocokan transaksi dan waktu transaksi "the end donk".

Saya kurang paham tentang pertanyaan agan, tetapi protokol Dandelion tidak bertujuan mencegah analisa/tracking berdasarkan waktu transaksi ataupun jumlah koin yang ditransfer. CoinJoin mungkin lebih cocok untuk masalah ini.

2. Apakah memungkinkan protokol ini mengeksekusi transaksi dengan beberapa wallet atau satu wallet saja?

Bisa, tidak ada batasan jumlah transaksi yang bisa melalui Dandelion. Masalah bisa mendukung beberapa wallet/tidak bergantung pada Bitcoin Client/Wallet-nya.

Hal ini mungkin cukup aman untuk menyembunyikan transaksi bitcoin skala besar, namun ketika melakukan proses WD ke fiat pasti pemerintah juga tahu melalui sistem audit perbankkan.

Tujuan Dandelion hanya untuk menyembunyikan node/IP yang membuat/broadcast sebuah transaksi. Kalau mau benar-benar aman/private, harus dikombinasikan dengan cara lain seperti menggunakan DEX/Decentralized exchange.

Play Services framework is almost certainly a privacy hole in Android. And probably a security hole too.

I say "almost certainly" and "probably" because it's closed source; only Google know what Play Services is actually doing, as only they have the source. I do not recommend Android if you want privacy or security.

Some android OS modification such as microG, SailfishOS, Replicant & LineageOS offers some privacy since they don't include/enable Google application/services by default.

But most users won't be interested since there aren't many good alternatives for Google Play Store and Google Play Games. There are many other application store, but the only open-source that i know is F-Droid which don't offer many application.

om perbedaannya apa antara Protocol DD dengan Mixer misal Bitcoin Mixer. Bukan kah prinsip kerja nya sama antara "Mixer" dan DD (Hidden).

Dandelion dan Cryptocurrency mixer memiliki tujuan yang mirip, tetapi perbedaannya sangat banyak. Diantaranya :

#DandelionCryptocurrency Mixer
1Open-source, sehingga semua proses bisa diverifikasiClosed-source, sehingga tidak bisa diverifikasi
2Koin dikontrol oleh agan, tidak mungkin dicuri oleh orang lainKoin dikontrol oleh mixer, mixer bisa mencuri koin again dengan mudah
3Harus percaya bahwa protokol tidak membocorkan data karena bug. Tetapi karena open-source, hal ini bisa diverifikasiHarus percaya bahwa mixer tidak menyimpan/menggunakan data tentang proses mixing agan
4User tidak perlu melakukan apapun, karena semua sudah diatur oleh wallet/clientUser perlu mengujungi website mixer, mengirim koin and memberikan alamat koin yang baru
5Privasi hilang jika memiliki kebiasaan yang buruk, seperti 1 alamat koin untuk semua halPrivasi hilang jika mixer menggunakan/membocorkan data mixing agan

tambahan om, berarti kl diterapkan apakah butuh Sync terlebih dahulu/gmna Om?.

Untuk sekarang, proses development Dandelion difokuskan untuk Bitcoin Core, sehingga perlu sync.

2. Node mengirim/broadcast transaksi ke node lainnya dalam

Gan, sepertinya untuk bagian ini ada yang kurang. Kalau mengacu ke thread agan yang berbahasa Inggris seharusnya tertulis (kurang lebih):

Sebuah node mem-broadcast transaksi ke node lainnya yang ada dalam satu sirkuit.

Terima kasih atas koreksinya gan Smiley

Apa manfaat Dandelion Secara Real bagi saya sebagai nubie di dunia crypto? Tentu selain manfaat bertambahnya wawasan.
Andai saja IP/nodes yang saya gunakan dilacak itu bukan masalah bagi saya.
Karena :
  • Saya bukan seorang kriminal  Cool
  • Saya tidak memiliki aset yang cukup besar

Hal tersebut benar jika anda tidak peduli dengan privasi agan dan tidak peduli jika data yang diketahui bisa digunakan untuk hal yang tidak berkenan, seperti menjadi target Hacker jika hacker mengetahui jumlah Bitcoin yang agan punya atau berusaha menteror agan dengan alasan yang terdengan masuk akal (meskipun kenyataannya tidak) seperti Bitcoin itu illegal.
Mungkin video Why Privacy Matters oleh Gleen Greenwald bisa membuat agan melihat privasi dari sudut pandang lain.

Saya pikir, Dandelion dapat disalah-gunakan oleh para cyber crimes untuk mencegah segala tindak-tanduknya diketahui oleh pihak berwajib dan pemerintahan. Mohon dikoreksi jika saya salah.

Saya tidak setuju karena kriminal sudah lebih pintar dalam menyembunyikan/menghilangkan jejak mereka dalam dunia maya. Berbagai solusi seperti menggunakan :
1. Tor / VPN untuk koneksi yang lebih aman
2. Bitcoin mixer untuk mencegah analisa/tracking Bitcoin
3. Monero, Zcash atau privacy-focused cryptocurrency

Menurut saya, Dandelion lebih berguna untuk meningkatkan privasi Bitcoiner tanpa merepotkan user dengan technical details. Bahkan user tidak perlu tau apapun tentang Dandelion karena semua sudah diatur oleh wallet/client.

Catatan
1. Thread ini adalah hasil terjemahan dengan modifikasi dari thread yang saya buat di [Discussion] Dandelion - A protocol to hide transaction origin
2. Semua spam atau FUD akan saya hapus
3. Silahkan bertanya jika masih bingung atau ingin belajar lebih lanjut
4. Mohon koreksi jika ada kesalahan dalam thread ini

Apa itu Dandelion?
Dandelion adalah sebuah protokol untuk mencegah pelacakan IP/nodes yang pertama kali mengirim/broadcast sebuah transaksi.

Mengapa Dandelion penting?
Pada umumnya, sebuah node selalu mengirim/broadcast sebuah transaksi ke node lainnya. Hal ini berarti node lainnya mengetahui siapa yang mengirim/broadcast transaksi tersebut. Sebuah grup atau pemerintah yang ingin melacak asal mula sebuah transaksi bisa menjalankan nodes sebanyak-banyaknya supaya bisa mengetahui node yang membuat/pertama kali mengirim/broadcast sebuah transaksi.
Sebuah makalah akademis (https://arxiv.org/pdf/1810.02466.pdf) menyatakan bahwa China memiliki kemampuan untuk melacak asal mula transaksi.

Peran Dandelion disini untuk mencegah orang lain mengetahui nodes yang membuat/broadcast sebuah transaksi.

Cara kerja Dandelion

1. Node membentuk sebuah sirkuit (privacy graph) yang berisikan kumpulan nodes lainnya.
2. Node mengirim/broadcast transaksi ke node lainnya dalam satu sirkuit.
3. Node selanjutnya (yang menerima transaksi) secara acak menentukan :
   A. Mengirim/broadcast transaksi ke bitcoin network (kemungkinan 10% pada umumnya)
   B. Hanya Mengirim/broadcast transaksi ke node selanjutanya di dalam sirkuit tersebut (kembali ke step 3)

FAQ
Q: Apakah perlu soft-fork/hard-fork?
A: Dandelion tidak perlu soft-fork maupun hard-fork karena hanya Dandelion tidak mengubah protokol Bitcoin dan hanya perlu diimplentasikan di Bitcoin Client (seperti Bitcoin Core) saja.

Q: Apakah Dandelion membuat penyebaran/propagation transaksi di Bitcoin network menjadi lebih lambat?
A: Sedikit lebih lambat, karena transaksi perlu "lompat"/hop melalui lebih banyak nodes. Tetapi perbedaannya tidak akan terasa.

Q: Siapa saja yang dapat menikmati keuntungan Dandelion?
A: Semua orang yang menggunakan wallet full-nodes dan SPV (dengan konfigurasi tertentu) yang mendukung protokol Dandelion.

Q: Kapan Dandelion dirilis?
A: Tidak ada tanggal pasti. Awalnya Dandelion direncakan rilis bersamaan dengan Bitcoin Core 0.17.0, tetapi diundur dan direncanakan rilis bersamaan dengan Bitcoin Core 0.18.0.

Q: Apakah ada cryptocurrency yang telah menggunakan Dandelion?
A: Ada, yaitu ZCoin, meskipun cara kerja secara detail agak berbeda.

If you're using Bitcoin Core, you can get list of your receiving address by click "File" > "Receiving address" on Menu Bar. Bitcoin Core generate lots of addresses, so there's no way it's empty.
If not, please tell us the name of wallet/client that you use and give proper link since your current link leads to your own desktop.


sorry for misunderstanding everyone here is the version and the receiving adresses tab that is empty https://imgur.com/a/PwQeovt

That's weird, AFAIK Bitcoin Core automatically generate address and show few of them on receiving address tab. I just moved my wallet.dat, then running Bitcoin Core (which means it automatically create new wallet.dat) and there aren't any address on receiving address tab. Looks like it's normal behavior and you don't need to worry about it (my nodes is fully synced, obviously).
Just choose "Receiving" icon/text and click request payment, then the result will be added to receiving address tab.

Also, is it fresh wallet or you've used it (to receive TX, send TX or request payment) previously?

Aside from whether this script is legit or not, the real questions are :
1. Why buy script if you can use built-in automated-bet / API?
2. Why buy script if you can look for strategy or formula at trusted / popular website?
3. How do we make sure the script isn't infected or backdoored, whether it's intentional or not?

551  Bitcoin / Development & Technical Discussion / Re: Is Bitcoin infrastructure too Chinese? What should be done technically? on: October 12, 2018, 08:12:40 PM
Then how about a group of developer upload encrypted code of the algorithm? They simply need to decrypt when it's needed.
That would still require trust in none of the developers leaking the selected algorithm.

True, but there aren't many choice in this case. Otherwise, the only choices are :
1. Picking acceptable PoW-algorithm that never seriously considered as SHA-256 alternative
2. Use flexible/configurable algorithm such as ProgPoW, but few parts of the algorithm/formula will be changed to prevent ASIC.

Maybe manufacturing the chips in China isn't really a problem. Many companies from other countries manufacture their products in China, and they control that the producers don't "tamper" with the design of their products. If the Chinese manufacturer manipulated the product, the customer would be able to charge a penalty for breaching the contract and change the manufacturer. An "open mining hardware" project could do the same thing, ensuring no Antbleed-style backdoors are implemented - and such a backdoor would be very easy to discover, above all if the firmware is open-source.

Once Bitcoin and the mining market becomes really big, it would be perhaps no problem to install production infrastructure outside of China able to deliver similar production costs.

Even if "open mining hardware" is popular and your scenario can't happen, i still think China still have someone advantage because :
1. Transportation cost is far lower if the chips is manufactured in China.
2. Faster transportation allows China to gain more edge since they're the first to use the chips in big scale.

But if mining on other country have maintenance/electricity price similar with China, then it's enough to prevent mining domination by china.
552  Economy / Gambling discussion / Re: What is better in poker: bluffing or playing only with good cards? on: October 12, 2018, 07:59:39 PM
It is extremely situational, if it's online poker, play only with good cards works better most time since people won't be deceived easily by words alone. Otherwise, there are 3 conditions/things we could consider before choose bluff or play with good cards :
1. Is enemy easily bluffed?
2. Can you find out/guess whether enemy pretend to be bluffed?
3. Are you good at bluffing (choosing good words, maintain poker face and good body expression)?

If there are at least 2 condition meets, bluffing should works better. Otherwise just play with good cards and totally ignore all enemy bluff attempt.
553  Bitcoin / Development & Technical Discussion / Re: Decrypt sha 512 on: October 12, 2018, 03:54:32 PM
I doubt you understand about hashing and encryption.

Both of them are different things and you can't get any data from hash alone. Hash useful to verify whether a message/file has been tampered or not and hash size always same no matter how big the message/file.

555  Bitcoin / Development & Technical Discussion / Re: Is Bitcoin infrastructure too Chinese? What should be done technically? on: October 12, 2018, 05:38:30 AM
It's not good to have an exact algorithm planned out, since then someone could make an ASIC for it in advance.

Then how about a group of developer upload encrypted code of the algorithm? They simply need to decrypt when it's needed.
Or choose ProgPoW since it's flexible and valid algorithm parameter/formula depends from previous block metadata (hash, merkle root, etc.).

It is odd, imo, too much concerns about ASICs and zero interest in the situation with pools.

Because potential solution/"solution" is known by more people Huh

I'm also a bit concerned about the "new monopolies" that could emerge after a PoW change. It may sound a bit naive, but - is there a possibility to create/fund an open hardware project for mining chips running the "new Bitcoin algorithm"? It's true however that major "chip foundries" are located in China, but there are at least some scattered around the world (mainly Europe and North America) which could step in for production.

I think it's possible. But, the competition with China won't gone since the cost to manufacture the chips is still cheaper on China.
556  Bitcoin / Development & Technical Discussion / Re: What is use of Checkpoints in a cryptocurrency? on: October 12, 2018, 05:24:04 AM
As you see, Bitcoin has removed checkpoints, so it's not as necessary as you think (it was removed because couldn't prevent any meaningful attack) but yeah, others have it too. The reason why they are using checkpoints is to provenet denial-of-service attack.

Additionally, the main reason to implement checkpoint was to prevent history manipulation where attacker attempt to make a node only connect to their nodes which contain different blockchain.

558  Other / Meta / Re: new board - Altcoin technical support. what do you think? on: October 11, 2018, 03:18:22 PM
It's great idea, even though your idea already mentioned few times in past (i also suggest similar things), but there aren't much attention or support. I also want to see "Altcoin Development & Technical Discussion" board though.

But, the reason Bitcoin technical support boards barely have spam because :
1. The moderator is Core developer and easily can identify spam/FUD
2. I think member who usually visit this boards actively report posts which violate rules

My doubt is finding qualified moderator and whether member will report bad-posts. There are another option such as Disabling Signature and don't count post on this boards for counting activity.
559  Bitcoin / Development & Technical Discussion / Re: Securing an Alt-Chain by Proof of Bitcoin Payment on: October 11, 2018, 01:59:51 PM
Can you please elaborate on these "low cost manipulations" and how they are different from manipulating any low hashrate altcoin?
Clearly when the altcoin is young, the hashrate is presumably low and anyone can cheaply attack it. In the above setup you don't need to buy mining equipment to perform the attack, you spend bitcoins doing it.

My point is people can attack young/minor altcoin with low cost, whether it uses PoW or PoP.

Besides, attackers (who wish to attack PoW-based coins) don't need to buy mining equipment, since they simply could spend their bitcoins to rent mining equipment to launch the attack. Various minor altcoin which listed on exchange including Bitcoin Gold has become the victim.

Regarding the blockchain bloat argument, I tend to think that this type of questions are best left for the market to decide. "Bloat" is a moral objection saying "useless tx", but I think all tx are equally useful as long as the sender is willing to pay the fee and miner is willing to mine. Plus, "buying altcoin security" sounds like a legitimate use case to me. Also there is a flip side that by paying miners (instead of burning electricity) we are increasing Bitcoin miners' reward thus contributing to Bitcoin security.

Can't argue against that, however the real problem is multiple altcoin miners make Bitcoin transaction, but only few altcoin miners got their blocks confirmed by network/become longest chain. This means some transaction become "useless".
560  Other / Meta / Re: I'm thinking of running a topic starting contest for non-english speakers. on: October 11, 2018, 11:24:58 AM
Some idea/suggestion :
1. Don't use pool to choose best topic, it's more suitable for most favorable topic and could be abused easily.
2. Allow topics about Mining/Cryptocurrency Legality

If this is not a problem, I would recommend discussion about Bitcoin regarding its technology (perhaps something with scalability).

Scalability isn't easy topic and heated discussion/ideology clash will happen because there are many different perspective. Something easier such as multi-signature and seed/mnemonic would be better.
