![]() ![]() Since we need a permanent 5V voltage, we take two 3.7V Li-Ion batteries of the type 18650 and connect them in series. The instructions on how to set up the solar cell can be found in this article. Many of them can also be mined with the Raspberry Pi. In addition to Bitcoin and Monero, there are also many other currencies – both technically improved coins ( Ethereum) and fun coins ( Dogecoin). This is one of the reasons why you can not trade Monero on most exchanges and the easiest way to get it is by mining. It is also based on a blockchain and can be mined, but here the transactions are concealed in such a way that they can not be traced. Now that we know what cryptocurrencies and blockchain in general are, the question arises, which currency is the best? Bitcoin was the first cryptocurrency, but there are countless others that have small differences.Ī decisive disadvantage of Bitcoin is that although the sender and recipient addresses are anonymous (hash values), every transaction in the blockchain can be precisely tracked – and as a result, Bitcoin is not quite as anonymous as one might think.Ī coin that regulates this differently is Monero. ![]() Here you will find a good, clear explanation on the subject: Plus, anyone who has the entire blockchain knows what transactions have taken place. Since these blocks are linked to one another (the so-called “blockchain”), no previous transaction can simply be deleted. Such a transaction is written in a subsequent “block” and shared with the network. Since all transactions take place in a peer-to-peer network, they have to be “verified” in a certain way, which is why you need third parties (the “miners”) who take on this job and are rewarded for their computing power (by using Bitcoins receives). Unlike our paper money, such “coins” are not printed but generated by making your computing power available. Simply put, cryptocurrencies such as Bitcoin are purely digital currencies with which transactions can be carried out – just like with real money. Note, however, that the hash rate varies from model to model.Įxcursus: What are Cryptocurrencies like Bitcoin, Monero and Mining? We also need soldering utensils and of course a Raspberry Pi (the model does not matter). Capacitors (I used a 100 uF capacitor for this, but you can also use slightly different values).A charging module for the battery: type TP4056.if necessary, a holder for two batteries. ![]()
