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
HBitcoin on GitHub; HBitcoin on NuGet; Background. A few years ago, I attempted to write wallet library, that was my first, learning Bitcoin project, called HiddenBitcoin.While I was not able to give out a stable release, I reused and polished a lot of the code I wrote there over the years. Type 1 deterministic wallets are the simpler of the two, which can create a single series of keys from a single seed. A primary weakness is that if the seed is leaked, all funds are compromised, and wallet sharing is extremely limited.

The Bitcoin Core client wallet would create 100 private key/public key pairs automatically via a Pseudo-Random-Number Generator (PRNG) for later use. These unused private keys are stored in a virtual “key pool”, with new keys being generated whenever a previously-generated key was used, ensuring the pool maintained 100 unused keys. (If the wallet is encrypted, new keys are only generated ...
