Overview In a previous tutorial, I shared the first published version of my uBitAddr project. This software and hardware project is a totally open source, open hardware, DIY offline address generator. It allows the user to generate a private key and the associated address for long-term storage, in something like a paper or metal wallet.
Overview Getting started with Bitcoin isn’t as intimidating as it would seem. In another tutorial, we discussed how to get started with a mobile wallet, using Bitcoin.com’s app or the Coinomi wallet. We learned how to install the wallet, safely back up our funds using the seed phrase, and get an address for loading up
Note: This article focuses on the development of MicroProver. See my slides for the full BTC2019 talk Overview Proof-of-work is a Bitcoin and blockchain topic of vital importance, as it allows transactions to occur without trusting an intermediary. However, understanding this concept also requires some computer science background. One needs to know about hashing algorithms,
This is a new series I’m introducing called “Code Companion”. These articles and videos highlight code projects of mine that are related to Bitcoin & cryptocurrencies. These projects can be helpful in understanding technical blockchain concepts. Explore and enjoy! Overview One of the most secure ways to store Bitcoin and other cryptocurrencies for the long
Overview One of the most interesting and powerful capabilities of the Ethereum network is the ability to create new currencies that operate on top of the base network. By using smart contracts, it’s possible to create a currency called a token without having to fork an existing currency’s code and create a new decentralized network.
Overview For someone that’s completely new to the concept of digital money, all the information out there can get a tad overwhelming. Fortunately, getting a practical start in using cryptocurrencies is actually fairly trivial with modern mobile wallets! Installing a proper wallet is the first step in a safe and successful journey into the crypto
Overview Segregated Witness, better known as segwit, is a soft-fork change to the core Bitcoin (BTC) protocol implemented to provide one possible scaling solution as well as other benefits. First, the use of segwit decreases the size of transactions (sort of) and provides a new way for the Bitcoin network to scale without a hard-fork
Overview Much like Bitcoin, Ethereum is a wildly popular cryptocurrency that allows its users to exchange value on a global, decentralized, censorship resistant platform. However, Ethereum goes beyond the capabilities of Bitcoin by adding a far more versatile scripting platform for the creation of “smart contracts” or “decentralized applications”. In order to facilitate this, the
