How to construct a transaction completely offline?
Imagine I'm in a prison and I only have a computer with a few megabytes of data left. I cannot download the whole blockchain (24.5 GB as of today) on my computer just to sign one transaction. External nodes aren't working because of buggy wallets I tried for hours. It's fairly possible to do this for bitcoin online:
And also by hand, because my warden took my computer, and some prisoners are passing me papers with unspent outputs and stuff. I only have to sign: 3. http://www.righto.com/2014/02/bitcoins-hard-way-using-raw-bitcoin.html I can't do any of this in monero why? I know there must be a way, just don't know how the tx is constructed. bro I need to long all my monero with 25X leverage now.(serious, I'm gonna do it. right after i know how to do this one transaction. I just cannot download the blockchain. I'm in a jiffy here.) From what I see: There exists a online transaction hash checker
I verified my tx, using my private viewkey and address I got the moneroj which are unspent. I want to spend it, how? I also see theres a tx pusher on that same site, and some other tools. Could someone explain how to use these tools in a step-by-step process?
Here you go : NBitcoin is a framework, not a full node implementation, but support communication with nodes through the protocol or with RPC. It is the most complete and user friendly API you will ever find in Bitcoin, deployable with nuget :) High test coverage. (approx. 200 tests, some ported directly from core )
Full port of the test suite of bitcoin core with their own data
Full script evaluation and parsing
Payment Protocol (BIP 70)
Payment URL (BIP 21,BIP 72)
Two Factor keys (BIP 38)
Stealth Address (Also on codeproject)
Recognize standard script and permit to create them
Object model faithful to the C++ API but with C# goodness
Simpler API (here is how to generate a key and get the address : new Key().PubKey.Address.ToString())
Bloom filter, partial merkle tree
Serialization of Blocks, Transactions, Script
Signing/verification with private keys, support compact signature for prooving ownership
AIMA, the library of the book this course focuses on most. I migrated it into .Net via IKVM. It is now listed in PKP's AI project.
Encog, Jeff Heaton's framework (see abovementioned book). We will use it in this course.
Accord.Net is probably the most used AI framework in the .Net world. It was not easy to choose, because on the one hand it is better oriented towards Vision/Robotics/Real-time applications, but on the other hand, it's code is more messy than others. All in all, it still is one of the best solutions.
Aforge.Net is the original framework on which Accord was built, and then maintained (How Accord absorbed Aforge remains unclear).
numl is another generalist library. It is quite cleanly programmed and popular, geared towards maths and machine learning.
Math.Net is the most exhaustive library for maths. It is used by many.
Quickgraph is a very good library to work on graphs (networks of entities). Although unfortunately not maintained anymore, it still is usable.
Sho is a microsoft environment to work with data, with connectivity to .Net and Python.
Good AI is an environment in which to design intelligent systems.
DiffSharp is a library to optimally compute derivatives.
Hype is a library to combine and optimize learning systems, using DiffSharp.
An article details implementation of Artificial Life (see architecture subsumption, a subject mentioned in the introductory class. It for example speaks about using genetic algorithms to build neural networks (see also SharpNeat and HyperNeat, above).
HiddenBitcoin: privacy centric, straightforward wallet library tutorial for C# developers on Codeproject
Hi guys, recently my free time is occupied by the development of an open source wallet, called HiddenWallet. The vision is to enable instant, anonymous Bitcoin transactions on every platform. Obviously Bitcoin is far from ready for this, nor my wallet, but I hope as the space is evolving we will be able to achieve the vision eventually, or at least gravitating towards it. During the development I felt the need to introduce an other layer between my user interface and the NBitcoin C# bitcoin implementation. I call this layer HiddenBitcoin. I finished the first part of it and I submitted a tutorial to Codeproject. I provide a very easy-to-use framework and if it turnes out I nailed it there might be a bunch of developers in the future who are going to build their Bitcoin stuff upon it and the library will limit them to a privacy by default mindset. Here is the article I published, surprisingly it already has 1.3K views in a few hours, that's a lot of geeks there. http://www.codeproject.com/Articles/1096320/HiddenBitcoin-High-level-Csharp-Bitcoin-wallet-lib Uber-super-special thanks for his work: NicolasDorier
You know that your Bitcoin Address is what you share to the world to get paid. You probably know that your wallet software uses a private key to spend the money you received on this address.. The keys are not stored on the network and they can be generated without access to the Internet. Cross platform Bitcoin wallet implementation in .NET Core for a CodeProject tutorial: Build a Bitcoin wallet in C# The wallet might also will turn out to be the first iteration of a dedicated wallet for a Bitcoin privacy improvement technique, called TumbleBit . TumbleBit will be integrated through NTumbleBit , however in a new repository with Bitcoin transfer In Bitcoin, everything is designed to make sure that the transactions go through. In this chapter we are going to introduce the basic concepts of Bitcoin by guiding you through a creation of simple bitcoin transaction "by hand". Breeze: Breeze Wallet, the first full-block SPV bitcoin wallet. BlockExplorer: A set of projects that can index and query stratis blockchains on the fullnode. BTCPay Server: A cross platform, self-hosted server compatible with Bitpay API. NTumbleBit: TumbleBit Implementation in .NET Core. BitPoker: Decentralised peer to peer poker, using Actually, my client had initially told me to integrate BlockChain.info API for bitcoin wallet, which I did. Later he provided me your tutorial to develop own wallet and now I am stuck due to my limited knowledge of Bitcoins/.Net Core and now my pending dues are blocked due to this. I was desperately in need of a solution so had reached out to
