![]() ![]() The downside here is that a hack or cyberattack could be a disaster because it could erase Bitcoin wallets with little hope of getting the value back.Īs for mining Bitcoins, the process requires electrical energy. This means Bitcoin will never experience inflation. Therefore, the total number of Bitcoins in circulation will approach 21 million but never actually reach that figure. At the moment, that reward is 12.5 Bitcoins. He (or they) reached that figure by calculating that people would discover, or "mine," a certain number of blocks of transactions each day.Įvery four years, the number of Bitcoins released in relation to the previous cycle gets reduced by 50%, along with the reward to miners for discovering new blocks. Satoshi Nakamoto, the founder of Bitcoin, ensured that there would ever only be 21 million Bitcoins in existence. And that work comes in the form of mining.īut let's take a step back. Like any other form of money, it takes work to produce them. There are thousands of cryptocurrencies floating out on the market now, but Bitcoin is far and away the most popular.īitcoin, Litecoin, Ethereum, and other cryptocurrencies don't just fall out of the sky. ![]() There had been several iterations of cryptocurrency over the years, but Bitcoin truly thrust cryptocurrencies forward in the late 2000s. Blockchain tech offers a way to securely and efficiently create a tamper-proof log of sensitive activity (anything from international money transfers to shareholder records).īlockchain's conceptual framework and underlying code is useful for a variety of financial processes because of the potential it has to give companies a secure, digital alternative to banking processes that are typically bureaucratic, time-consuming, paper-heavy, and expensive.Ĭryptocurrencies are essentially just digital money, digital tools of exchange that use cryptography and the aforementioned blockchain technology to facilitate secure and anonymous transactions. Think of it as a kind of highly encrypted and verified shared Google Document, in which each entry in the sheet depends on a logical relationship to all its predecessors. Essentially, it's a shared database populated with entries that must be confirmed and encrypted. ![]() If you want to give the housing some extra protection, you can wrap the seam in a piece of black electrical tape like we did.Blockchain tech is actually rather easy to understand at its core. These bolts will attach to the nuts that you placed in the previous step. The back piece of the housing was screwed on with 4 3mm bolts. We made sure not to loosen any wires connected to the Raspberry Pi. Then, the housing was then carefully snapped together. These nuts will be used to hold the housing together. the third front housing piece has to be screwed on after the display has been slotted in.Īfter connecting the display to the Pi, we add 3mm nuts to the 4 extensions on each side of the top piece. The right side has a wider frame portion so that the wires can wrap around to the Raspberry Pi. The combined display unit was slotted into the front piece of the housing. A pair of tweezers made it easy to hold the small hardware in place. The housing parts have small tabs on the sides that allow you to screw them together with small 2.5mm nuts/bolts. The back has 4 counterbored holes so that the screws can sit flush. The Raspberry Pi Zero W was slotted into the middle, back piece with 4 2.5mm nuts/bolts. This step is less critical if you plan on gluing the parts together. A box cutter helped deburr the pieces so that they fit together better. Our print bed was too small to print the entire front/back so we cut them into three pieces on the back side and four pieces on the front. To make the housing, we 3D printed a few PLA parts. ![]()
