The Revolution Will Not Be Centralized

Denovo

Denovo will eventually be a very flexible and easy to use tool with lots of features from a simple offline tool to handle keys and transaction signing to a full client
capable of working as a full node or a SPV node and ultimately a second layer node (such as Lightning network node).
Currently Denovo is in beta and has very limited features listed below:

• TestNet miner: a simple but powerful miner to mine testnet blocks and broadcast them used only for testing things that can not
  be tested otherwise.
• Message encryption: encrypt and decrypt messages using Elliptic Curve Integrated Encryption Scheme (ECIES).
• Transaction verifier: verify any bitcoin transaction by entering its raw hex and all its UTXOs.
• WIF helper: an experimental feature to convert WIFs to mnemonic and back
• Push transaction: broadcast transactions to other bitcoin nodes on mainnet and testnet

Using the latest .net core version with AvaloniaUI
Denovo can run on any operating systems.

Bitcoin.Net

The backbone of Denovo, Bitcoin.net is a stand alone bitcoin library written completely in C# and from scratch (no code translating)
with no dependencies.
It is released as a different project so that it could be used by any other third party projects.
Check out releases for the current version (versioning convention).
The current implementation is covering almost the entire bitcoin protocol, there may be some missing parts or some bugs.
Please report any problems that you encounter or any feedback that you may have.

Bitcoin.Net can be downloaded from Nuget:

Using Package manager in Visual Studio:

Install-Package Autarkysoft.Bitcoin

Using .Net CLI:

dotnet add package Autarkysoft.Bitcoin

Current Features

• Full xml documentation of the code explaining what each member does, exception that may be thrown, examples if needed,…
• Neatly categorized namespaces for ease of access: Blockchain, Cryptography, P2PNetwork are the 3 main ones and there are
  Encoders, ImprovementProposals covering the rest.
• Near 100% test coverage (for finished parts only, for now).
• Loosely coupled implementation of blocks, transactions and scripts making it easy to test and scale.
• Stand alone cryptography namespace making it possible to optimize functions for bitcoin
  (only some parts are currently optimized: Hashing and KeyDerivationFunctions namespaces)
  • Asymmetric: ECC (unoptimized and untested)
  • Hashing: SHA-1 (unoptimized), SHA-2 (256/512), HMAC-SHA (256/512), RIPEMD160, RIPEMD160 of SHA256 (aka Hash160) all optimized
  • KeyDerivationFunctions: PBKDF2, Scrypt both optimized
  • RFC-6979: Optimized. Also an extra entropy is added so that signer can grind to find low R values to a fixed length (<32).
• Implementation of improvement proposals, consensus related BIPs are part of the library and optional bips (eg. BIP-32)
  are in separate classes. Currently:

Future plans

• Optimization of the library
• Complete testing of remaining parts
• Add more relevant and useful BIPs
• Add support for Lightning Network
• Explore more ideas for a better Bitcoin (eg. block compressions and P2P protocol) to add under Experimental namespace.
