bitcore - A full stack for bitcoin and blockchain-based applications

•    Shell

---

Bitcore is a infrastructure to build Bitcoin and blockchain-based applications for the next generation of financial technology. It is a full bitcoin node, your apps run directly on the peer-to-peer network. For wallet application development, additional indexes have been added into Bitcoin for querying address balances, transaction history, and unspent outputs.

eth-lightwallet - Lightweight JS Wallet for Node and the browser

•    Javascript

---

A minimal ethereum javascript wallet. LightWallet is a HD wallet that can store your private keys encrypted in the browser to allow you to run Ethereum dapps even if you're not running a local Ethereum node. It uses BIP32 and BIP39 to generate an HD tree of addresses from a randomly generated 12-word seed.

bitcore-node - Extensible full node using the Bitcore build of Bitcoin

•    Javascript

---

A Bitcoin blockchain indexing and query service. Intended to be used with as a Bitcoin full node or in conjunction with a Bitcoin full node.There is no upgrade path from previous versions of Bitcore Node due to the removal of the included Bitcoin Core software. By installing this version, you must resynchronize the indexes from scratch.

bitcoin-testnet-box - Create your own private bitcoin testnet

•    Makefile

---

You must have bitcoind and bitcoin-cli installed on your system and in the path unless running this within a Docker container (see below).This will start up two nodes using the two datadirs 1 and 2. They will only connect to each other in order to remain an isolated private testnet. Two nodes are provided, as one is used to generate blocks and it's balance will be increased as this occurs (imitating a miner). You may want a second node where this behavior is not observed.

btcwallet - A secure bitcoin wallet daemon written in Go (golang)

•    Go

---

btcwallet is a daemon handling bitcoin wallet functionality for a single user. It acts as both an RPC client to btcd and an RPC server for wallet clients and legacy RPC applications.Public and private keys are derived using the hierarchical deterministic format described by BIP0032. Unencrypted private keys are not supported and are never written to disk. btcwallet uses the m/44'/<coin type>'/<account>'/<branch>/<address index> HD path for all derived addresses, as described by BIP0044.

trezor-agent - Hardware-based SSH/PGP agent

•    Python

---

This project allows you to use various hardware security devices to operate GPG and SSH. Instead of keeping your key on your computer and decrypting it with a passphrase when you want to use it, the key is generated and stored on the device and never reaches your computer. Read more about the design here. You can do things like sign your emails, git commits, and software packages, manage your passwords (with pass and gopass, among others), authenticate web tunnels and file transfers, and more.

Bitcoin - Most popular Crypto Currency

•    C++

---

Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system.

bitnodes - Bitnodes is currently being developed to estimate the size of the Bitcoin network by finding all the reachable nodes in the network ·

•    Python

---

Bitnodes is currently being developed to estimate the size of the Bitcoin network by finding all the reachable nodes in the network. The current methodology involves sending getaddr messages recursively to find all the reachable nodes in the network, starting from a set of seed nodes. Bitnodes uses Bitcoin protocol version 70001 (i.e. >= /Satoshi:0.8.x/), so nodes running an older protocol version will be skipped.See Provisioning Bitcoin Network Crawler for steps on setting up a machine to run Bitnodes. The Redis Data contains the list of keys and their associated values that are written by the scripts in this project. If you wish to access the data, e.g. network snapshots, collected using this project, see Bitnodes API v1.0.
