p2p

I was making a simple file transfer program through IRC and when I was reading up I saw that IRC when sharing a file creates a direct connection between the two users independent of the server (DCC, Direct Client Connect). After searching a while I have found this: Direct Connect and Advanced Direct Connect . None of these pages answer this question that I can't get out of my head: Is P2P data transfer possible without any user doing a special port-forward? An intermediate server which helps set up the connection (as in the IRC examples) is allowed. The data transfer itself must be independent

I'm trying to implement peer-to-peer messaging and file sharing utility within LAN, So does WCF supports p2p? Does any one tried file sharing trough WCF? Yes, it does. Please see How To Design State Sharing In A Peer Network : When researching the various ways in which an election scenario might be implemented, I discovered that there is an attribute in WCF that allows you to indicate the maximum number of hops that a particular message will travel. After seeing this, it became obvious that there was a means for sharing state in a peer network that not only required no central server, but was

I want to make connection between two devices over WiFi using GameKit. Apple's documentation says If an Internet connection is chosen, your application must dismiss the peer picker dialog and present its own user interface to complete the connection. This is what i do - (void)peerPickerController:(GKPeerPickerController *)picker didSelectConnectionType:(GKPeerPickerConnectionType)type { if (type == GKPeerPickerConnectionTypeOnline) { picker.delegate = nil; [picker dismiss]; [picker autorelease]; [alert setTitle:@"\n\n\n"]; [alert setMessage:@"Looking for other iPads, iPhones or iPod touches...

比特币（Bitcoin）的概念最初由 中本聪 在2008年11月1日提出，并于2009年1月3日正式诞生 [1] 。根据中本聪的思路设计发布的 开源软件 以及建构其上的 P2P 网络。比特币是一种P2P形式的 虚拟 的加密数字货币。点对点的传输意味着一个去中心化的 支付系统 。 与所有的货币不同，比特币不依靠特定货币机构发行，它依据特定算法，通过大量的计算产生，比特币经济使用整个P2P网络中众多节点构成的 分布式数据库 来确认并记录所有的交易行为，并使用密码学的设计来确保货币流通各个环节 安全性 。P2P的去中心化特性与算法本身可以确保无法通过大量制造比特币来人为操控币值。基于密码学的设计可以使比特币只能被真实的拥有者转移或支付。这同样确保了 货币 所有权与流通交易的匿名性。比特币与其他 虚拟货币 最大的不同，是其总数量非常有限，具有极强的 稀缺性 。 来源： https://www.cnblogs.com/wwbb/p/11831097.html

I've been trying to get into dat recently and I'm wondering about the difference between dat and the hyperdrive module. TL;DR: Dat is for end users and Hyperdrive for developers. Dat is a user friendly interface for sharing distributed files. Anyone can download the program and use it to securely share files peer-to-peer. Under the hood it uses Hyperdrive which is a Node.js package that aims to implement the same APIs as Node.js' core fs module, but it also offers data replication features. There also is a dat-node module to use Dat's features in your own Node.js applications. With dat-node it
