Defining Solidity
Solidity can be described as a browser based programming language that allows the user to write and deploy ethereum smart contracts on the main network. Solidity and Blockchain can be compared to the time when Java was being written and deployed using early programs like notepad according to the start of chapter 6 titled Fast-Track Application Tutorial on page 125. Solidity, in simple terms means to be rigid or firm in stature, and although Solidity can be used straight off a browser, clients such as INFURA will be needed to implement the code onto the Blockchain.
Similarities to other Programming Launguages
- Solidity is Turing complete meaning memory allocation can be changed and prompts such as if/else/while and do-while's may be implemented in the code similar to c,c++,java, and python.
- Statically typed language including data types: Boolean (true/false value returns), Integer (int,uint, signed and unsigned), Ethereum Addresses, Members of Addresses (Additional Informaton Below), Mappings, Date and Time, Structures (Structs), String Literals, and Hexadecimal literals.
Block / Transaction Property Syntax & Cryptographic Functions
How MetaMask Eliminates the Need For Web2, and Makes DAPPS Function Through A Local Browser:
To start off, I would like to give a brief description of MetaMask. MetaMask is a browser extension that can be added to known browsers like Chrome and Brave Browser. The main problem that this extension is tackling is making the Blockchain accessible to the average user by allowing regular browsers to access Web3. Fea;tures of MetaMask are as follows:
- Automatic encryption of Private Keys
- Seed phrases (12) given to access account in case of lost passphrase
- Provides an Ethereum Wallet inside your browser.
- Supports Ropsten, a test-net where gas fees are nonexistent as their is no real value among the Blockchain
Remix, The Most Used Solidity Editor
Remix allows the user to compile and deploy an Ethereum Smart Contract using MetaMask
Truffle
The Truffle Framework "compiles your Blockchain contracts, injects them into your web app, and even runs a test suite against them" as stated on page 143 of Blockchain preceding the Summary section of chapter 6.
Conclusion / Summary
