What kind of Ethereum is Ganache

1. In solidness, a contract consists of a set of code (contract function) and data (contract state). The contract is located at a special address on the Ethereum blockchain. uint storedData; This line of code declares a state variable, named storeddata, of type uint (256 bits unsigned integer). You can think of it as a storage unit in a database. Just like managing a database, you can query and modify it by calling functions. In Ethereum, usually only the owner of the contract can do so. In this example, the functions set and get are used to modify and query the values of variables, respectively

like many other languages, when accessing state variables, it is not necessary to add a prefix such as this

this contract can't do a lot (limited by Ethereum's infrastructure), it just allows anyone to store a number. And anyone in the world can access this number. There is no reliable way to protect the number you publish. Anyone can call the set method to set a different number to cover your published number. But your numbers will remain in the history of blockchain. Later we'll learn how to add an access limit so that only you can change the number

token example

the next contract will implement a cryptocurrency in the simplest form. Taking money in the air is no longer a magic trick. Of course, only the person who creates the contract can do it (it's also very easy to use other currency issuance modes, just to realize the differences in details). And anyone can send money to others, without registering a user name and password, as long as there is a pair of Ethereum public and private keys

note
this is not a good example for online solidness environments. If you use the online solidity environment to try this example. The address of from cannot be changed when the function is called. So you can only play the role of a coiner, you can cast money and send it to others, but you can't play the role of others. This online solidity environment will be improved in the future.

2. Types of chocolate: it can be divided into three categories: dark chocolate, milk chocolate and fillings. This paper introces the classification of sandwich chocolate which is very popular abroad but not known to most customers at home: gianja sandwich chocolate: it is made of finely ground almond, hazelnut or walnut and sugar mixed with dark chocolate or milk chocolate. It often appears as round triangles in small packages with tin foil on the outside. Praline sandwich chocolate: This proct is very similar to giangia sandwich chocolate, except that it is usually coated with milk chocolate or dark chocolate. In Belgium, this kind of chocolate is very popular. Its sweet whipped cream sandwich has become a special variety of Belgian chocolate. Truffles, Parrt and Ganache: These are the best chocolate flavors. Ganache chocolate sandwich is a mixture of chocolate and cream, usually with some butter added. It also rolls through cocoa powder, icing or finely ground nut powder to form a simple travoltaire sandwich. But usually, it is dipped or coated with a layer of tempered chocolate. The Pareto sandwich is like a flat garner sandwich. One method of coating is to dip a round or square garner chocolate sandwich into the heated chocolate, and then tap it on a marble slab covered with gold leaves, which can leave two or three distinctive traces at the bottom of the chocolate. The key technology of making Pareto chocolate and travle chocolate is to make Ganache chocolate with light taste, so that its flavor and the flavor of the outer layer of chocolate coating complement each other< It can be seen that French Ganache is not a brand but a series of procts, which generally refers to the sandwich chocolate wrapped by a thin layer of icing, cocoa powder and nut powder~~
