As new data comes in, it is entered in a fresh block. Unlike a typical digital database, blockchain stores data in blocks that are then chained together. Virtually anything of value can be tracked and traded on a blockchain network, reducing the risk and cutting costs for all involved. ![]() Their mining is painstaking, costly and only sporadically rewarding.īlockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. Cryptocurrencies are digitally mined, where very sophisticated computers solve extremely complex computational mathematics problems. They carry a pre-determined store value of their own, just like any other fiat currency like the US dollar or the Indian rupee. ![]() They are tokens that can be used as a form of payment in exchange for online goods and services. However, they are often criticised for the possibility of misuse in illegal activities, exchange rate volatility and the vulnerability of the infrastructure underlying them.Ĭryptocurrencies work using a technology called blockchain. Plus, the digital structure facilitates free portability across geographical borders, divisibility and transparency. Because cryptocurrencies do not have an underlying economic base, they are inflation-proof. Such currencies, theoretically, are immune to government interference or any kind of manipulation. They are built on the blockchain network technology, which ensures transparency and helps track every transaction. Cryptocurrencies are decentralised, meaning that no authority regulates them. They have their own store values, and are designed to use as a medium of exchange for buying goods or services. Cryptocurrency is a digital or virtual coin secured by cryptography, which makes it next to impossible to counterfeit. The big difference is, here there is no owner-issuer and it would, at least in theory, be accepted globally. 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.Ever received a paper token from your next-door paan shop in lieu of a small change, which he would accept the next time you visit him? Imagine that token digitally, and that's your cryptocurrency. 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. ![]()
