Overview In my recent tutorial on tokenization, I showed a possible future where we might trade assets like homes, cars or even lawnmowers on the blockchain. I built a fun prototype to demonstrate this concept – using a Bitcoin Cash token, a Raspberry Pi, and my trusty lawn tractor! This tutorial is a technical look
Overview In the cryptocurrency world, ownership of your money is controlled by cryptographic private keys. These keys are used for deriving your receiving addresses and ultimately for spending funds. For obvious reasons, secure storage of these keys is absolutely critical for any Bitcoin user, as anyone with the keys can control the funds at that
Overview Several years ago during my early journey into the Bitcoin space, I heard Andreas Antonopoulos discuss the idea of tokenization on Joe Rogan’s podcast. He was imagining a future in which we no longer trade car titles or mortgage deeds through government agencies. Instead, we would represent those assets as tokens on a blockchain.
Overview At the core of cryptocurrencies lies the science of cryptography. These mathematically secured and provable algorithms allow currencies like Bitcoin to be built in a way that’s peer-to-peer instead of based on corporate or governmental trust. One of the key classes of cryptographic algorithms used in cryptocurrencies is hashing algorithms – powerful one-way functions
Overview Many of the viewers of my tutorial on what happens when you send BCH to a BTC address have asked for more specific help on how to recover funds in this scenario. Fortunately, not all is lost if this happens – it just depends on the context. For non-custodial wallets (where the user controls
Overview Unfortunately, sometimes Bitcoin private keys are lost. Users destroy wallets, throw away hard drives, or simply never backup keys in the first place. A seemingly obvious solution to the problem of a lost key might be to try and “guess” all the possible keys until you find the one that unlocks your addresses. One
Overview One of the biggest perks of offline wallets (like paper wallets and hardware wallets) is the ability to store private keys away from prying eyes. In previous code companions, I talked about the challenges of building uBitAddr, a custom offline keypair generator that works with BCH, BTC, LTC, and ETH. However, you probably want
Overview On October 31st, 2008, Satoshi Nakamoto graced the world with his vision for a peer-to-peer electronic cash system called Bitcoin. The cryptocurrencies we use today started with this abstract and the ideas contained within. I highly recommend anyone interested in Bitcoin or other open blockchain projects read the original whitepaper, but it can be
