San Francisco merkezli cüzdan servis sağlayıcısı GatePay, çifte-harcama (double-spend) saldırılarını kriptografik olarak engelleyerek ağdaki işlem onay sürelerini bekleme gereksinimini ortadan kaldıran açık kaynak kodlu merkezsiz bir yazılım cüzdanı olmasıyla biliniyor. Anında ve düşük maliyetle güvenli işlemler sunmayı kendine amaç edinmiş olan Gatepay cüzdanını kullanmak oldukça kolay. Cüzdanı cihazınıza indirdikten sonra hızlı bir şekilde ödeme alabilir veya başka birine ödeme gönderebilirsiniz. Türkçe olarak kullanabileceğiniz cüzdan; Bitcoin, Litecoin, DASH, DOGE ve Ethereumu desteklemektedir. 14 farklı ülkede cüzdan servis sağlayıcısı hizmeti veren şirket, Ocak 2019 ile birlikte İngilizce, İspanyolca, Almanca, Fransızca ve Japonca ile birlikte Türkçe dil desteğini Android ve iOS yazılım cüzdanları için devreye sokmuş olmakla birlikte Şubat 2019 itibariyle Türkçe kullanıcı desteği (Support) hizmetini faaliyete geçirecek. Rakibi BitPayden farklı olarak GatePay şu anda, yukarıda bahsettiğim desteklenen 5 farklı kripto para protokolü için anlık (zero-conf) on-chain ödeme işlemlerine izin veriyor. Kullanıcılar kendi özel anahtarlarına (private key) tam erişim sahibi olmakla birlikte kendi belirledikleri güvenlik soruları ve 6 haneli pin kodu üzerinden kolayca cüzdan yedeklemesi yapıp dünyanın her yerinden kripto varlıklarına erişebiliyorlar.

Doesnt Bitpay have the same service as your project? They also dont like offchain solutions and have made sure that everything stays onchain by adding BCH in their accepted coins because its more scalable.
What would be your technical advantage over Bitpay?
Yeah BitPay is on-chain solution but it's for ordinary payment transactions, not for instant transactions. Online merchants using BitPay need to be sure their incoming transactions are confirmed thats because buyers can double-spend their unconfirmed payments. >> https://support.bitpay.com/hc/en-us/articles/115002990823-How-do-I-prevent-double-spend-fraud-on-unconfirmed-payments-BitPay is for online merchants not for physical merchants this is done so when you make a bitcoin payment for e-commerce with BitPay it does not matter when your transaction will be mined. Let say you bought something online through BitPay and your transaction is confirmed 3 hours later, once its confirmed then online merchant post your order. In the contrast way in terms of physical commerce it's essential to make instant payments because nobody would wait for 10 minute to buy a cup of coffee from a local store. That's why bitcoin is only used for a store of value and investment tool rather than used for daily payments. Okay I understand now, ty. But why do you have hesitations in using offchain solutions like Lightning Network? Wouldnt your service be doing transactions offchain like Lightning Network, but a centralized version? Comparing to Lightning Network, on-chain has 3 main advantages over LN in terms of spend flexibility, macro-payments, integration easiness and offline payments. a) Spend Flexibility LN uses payment channels and you need to lock your funds into a multi-sig address. You are not allowed to spend your funs outside LN and (probably) outside your payment channel. Each payment channel has a deadline so you have to wait till a certain time (locktime) to redeem rest of your funds back which is a very significant problem. b) Macro-payments LN is built for only micro-payments, not for non-micro payments due to some technical limitations. Underlying reason is you have a connection path on your payment channel and each node have to be funded at least the amount of your payment. Lets say you want to make a payment about 1 BTC through LN each node on your path have to be funded at least 1 BTC which is likely impossible. c) Integration easiness LN scales existing blockchains but it's a different structure than blockchain, it's a separate galaxy. Even blockchain adoption is not happened but existing wallets, exchanges, services, ATMs are all using blockchain protocol while LN offers another protocol. Both merchant and customer have to maintain commerce on same protocol, they need to use a LN integrated wallet for commerce. d) Offline payments Trade on LN happens only between peers so each peer have to be uptime as much as possible. Peers need to operate 7/24 online nodes otherwise payment channel crashes. On blockchain each node stores same copy of ledger. So peers don't have to be 7/24 online because other nodes are storing their transaction data alongside rest of chain data. Yeah but wouldnt your service be doing offchain transactions or function like a centralized money processor for BTC users like BitGo or a combination? I read that BitGo also has instant transactions but for a higher fee. BitGo has instant transaction feature but they are using multi-signature addresses in a centralized way. I think on-chain is the best approach, transactions should be maintained on the main blockchain. |

As far as I can understand from the technical details, GatePay will support bitcoin but how will you make everything in your whitepaper work? Can you please elaborate it? IMO, Since the buyer needs to connect to the vendor's node first, this project will require you to ask for the help of experts with lots of achievements in coding blockchain related projects. Also, will GatePay support other cryptocurrencies besides bitcoin?
Our protocol is called "protected transaction" and it has two implementations which are decentralized and centralized implementations. For decentralized one we need to build an open p2p network which will be handled in the future. Right now GatePay uses centralized implementation which we store "protected transaction" (2nd transaction) on our server (not private key, signed hex transactions which are ready to release). Our servers run nodes to detect double-spend attacks and release these transactions in double-spend case for merchants. Its an already working product supporting bitcoin, ether, litecoin, doge and dash. You can get it from app store and playstore as a software wallet. https://itunes.apple.com/au/app/gatepay/id1306809030?l=tr&ls=1&mt=8https://play.google.com/store/apps/details?id=air.gatepay |

This is an interesting idea! A couple pieces of feedback:
There are some typos in the blackpaper. (I like the idea of black, though!)
On Page 4, for example: In the case if double-spend attempts prevented by a mechanism there will no more problem existed.
I think it might worth investing in having an editor look through the document; perhaps for a bounty?
My other main question is about the value of the "instantaneous" transactions. Retailers today are already waiting ~30 days to receive their money in Fiat from Mastercard/Visa. My suspicion would be that 10 minutes is not too long for them.
Do you think that this "instant" value proposition is mostly for the p2p user?
Yeah you're right document is very draft now I'll fix it as soon as possible. In the perspective of merchants yeah 10 min is not such a time but the problem is buyers need to wait that time (10 min) because if a merchant accept an unconfirmed transaction as a payment and let customer leave, then customers can double-spend their payment transactions by including higher fee to redeem their funds payback. GatePay solves this problem by preventing double spend attacks targeting unconfirmed transactions. Protocol is not making transactions "instantaneous" it makes payments "instantaneous". Transaction still estimates about 10 min but payment accepted instantaneously by payee. |

Bitcoin' de "balance" diye bir kavram yoktur, UTXO (Unspent Transaction Output) vardır. Bakiye "UTXO" ların toplamıdır. O yüzden UTXO komutuna bir bak. Ethereum ve ethereum türevi zincirlerde ise "Account" yapısı vardır o yüzden her adrese bağlı "balance" kavramından söz edebiliriz.

Decentralized cüzdanlar (coinbase, xapo gibi) kullanıcılarının private keylerini kendi merkezi sunucularında barındırır ve transactionlar orada imzalanır. Decentralized cüzdanlarda ise private key kullanıcıda bulunur, transactionu kullanıcı kendi imzalar ve sonra işlem cüzdan servis sağlayıcısının node sunucusu ile ağa salınır. Görünüşe göre coinomi diye bir cüzdan halihazırfa varmış ama kullanıcı arayüzü deneyimi açısından eksik olduğunu düşünüyorum.

Örneğin windows ve linux da farklı işletim sistemleri ama ikisine de Bitcoin Daemon kurarak aralarında P2P haberleşmesi sağlayabiliyoruz. Aynı şekilde farklı işletim sistemlerinden cep telefonlarını da birer bilgisayar düğümü gibi kullanıp kendi aralarında P2P sync sağlayabilir miyiz?

Merhaba arkadaşlar bildiğiniz gibi bitcoin ledgeri ~200 GB gibi bir boyut kaplıyor ve böyle bir zincir verisinin mobil uygulamalarda işletilmesinin pek bir fizibilitesi yok. Depolama sorunun geçecek olursak anladığım kadarıyla cep telefonlarının kendi aralarında P2P mesajlaşması da pek mümkün görünmüyor. Günümüzde tüm blok zinciri uygulamalarına bakacak olursak ancak bilgisayar düğümleri kendi aralarında web socket ile P2P iletişimi kurabiliyor. Mobil cihazların birer düğüm sunucusu gibi kendi aralarında sync edilmesi ne kadar mümkün? Bildiğim kadarıyla iOS cihazlar kendi arasında apple ekosistemi içerisinde Wi-Fi ye bağlı olmak koşuluyla (router) "MultipeerConnectivity" kütüphanesi ile P2P iletişimi kurabiliyorlar. Farz edecek olursak bir iOS tam düğümü ile bir Android tam düğümü arasındaki bir P2P iletişimi mümkün değil diye düşünüyorum çünkü mobil cihazlar günümüzde client olarak görülüyor ve mobile computing daha çok ilerleme kaydetmesi lazım. Biri beni bu konu hakkında aydınlatabilir mi? Şimdiden teşekkürler.
