Monitors crypto mining pools and coins in real-time and finds the most profitable for your machine. Simply edit a batch file with your Bitcoin address or username and start mining. You will start earning even during benchmarking! MultiPoolMiner is more profitable than Nicehash Miner 2 and Nicehash Miner Legacy as it uses direct pool mining. With less than 0.7% minimum fee. It supports a great number of mining pools, such as CryptoNight, Ethash, Equihash, Groestl, Keccak, Lyra2RE2, Lyra2z, MyriadGroestl, NeoScrypt, Quark, Qubit, Scrypt, SHA256, Skein, X11, and Yescrypt. Some pools overestimate the projected profits. By default MPM will reduce the projected algo price by a correction factor (actual_last24h / estimate_last24h) to counter the pool overestimated prices. MPM supports customized configuration via config files.

Ethereum Wallet is a gateway to decentralized applications on the Ethereum blockchain. It enables you to hold and secure ether and other crypto-assets built on Ethereum, as well as write, deploy and use smart contracts. Mist Browser (formerly Ethereum Dapp Browser) is the end-user interface for Ethereum. It's the tool of choice for browsing and using Dapps and is specifically designed for non-technical users.

Go Ethereum is the official Golang implementation of the Ethereum protocol, a decentralized computing platform that runs smart contracts and applications. There are three original implementations of Ethereum and along with C++ and Python, Go Ethereum is one of them, written in Go. Go Ethereum comes with several wrappers/executables. It is fully open source and available as a standalone client called Geth that you can install on just about any operating system, or as a library that you can embed in your Go, Android or iOS projects.

Monero is a secure, private, untraceable cryptocurrency. It is decentralized-- dependent on a distributed peer-to-peer consensus network where every transaction is cryptographically secured. With Monero you are your own bank, you control your funds and can spend safely. No one else can see your balances, track your transfers or any other transactions unless you allow them to. Monero uses ring signatures, ring confidential transactions, and stealth addresses making it absolutely private and untraceable. No transactions can ever be linked to a particular user or real-world identity. And because it is private by default, it is fungible or mutually interchangeable, and cannot be blacklisted due to their association with previous transactions.

Bitcoin is a decentralized P2P electronic cash system without a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of the network to check for double-spending.

Corda allows businesses to enable private transactions using the blockchain seamlessly.

c-lightning is a a BOLT-compliant Lightning implementation by Blockstream [2] written in C language. Version 1 of c-lightning was released on August 8th, 2015, and has since been under active beta development. c-lightning runs on Linux. The Lightning Network is an off-chain, routed payment channel network built on top of the Bitcoin blockchain. The network consists of nodes connected by peer-to-peer channels. This allows low cost, near-instant payments to be trustlessly routed across the network via connected nodes. On top of complying with all BOLT standards, c-lightning is developing an architecture for plugins. Plugins can be built to extend the c-lightning command line API. There are a number of developer tools, libraries and plugins that exist for the c-lightning implementation.

Bitcoin Black Core is a peer-to-peer electronic cash system that aims to become sound global money with fast payments, micro fees, privacy, and high transaction capacity (big blocks). In the same way that physical money, such as a dollar bill, is handed directly to the person being paid, Bitcoin Black Core payments are sent directly from one person to another. As a permissionless, decentralized cryptocurrency, Bitcoin Black Core requires no trusted third parties and no central bank. Unlike traditional fiat money, Bitcoin Black Core does not depend on monetary middlemen such as banks and payment processors. Transactions cannot be censored by governments or other centralized corporations. Similarly, funds cannot be seized or frozen — because financial third parties have no control over the Bitcoin Black Core network. Bitcoin Black Core combines gold-like scarcity with the spendable nature of cash. With a limited total supply of 10,5 million coins. Transactions are fast.
