Hi, I'm Yusuf Erdoğan Blockchain developer. Developing on EVM with Solidity.
ETHEREUM TRANSACTIONS
An Ethereum transaction is a message sent from one Ethereum account to another Ethereum account that includes instructions to execute a specific action, such as transferring Ether or invoking a smart contract function. Transactions must be signed by the account owner using their private key and are broadcast to the Ethereum network for validation and inclusion in the blockchain. Once a transaction is confirmed and added to a block in the blockchain, it becomes immutable and permanent. Transac...

Hierarchical Deterministic Wallets (BIP-32/BIP-44)
Let’s learn the meanings of terms.Deterministic means that keys are no longer created randomly, but instead generated as part of a linked chain. Regular backups are no longer required as long as the private-key seed that created the chain is safe. This makes key management very simple, and even allows easy caching of the master key in a paper wallet or cold storage--only having child keys stored on more vulnerable computer hardware.Hierarchical means that the chain of keys is ranked so that l...

Solidity:Pure And View Functions
Functions can be declared as view if it is not modifying blockchains state. In our context, blockchain state is the value of the number variable. setNumber method changes the value of the variable so it cannot be declared as view. But GetNumber only reads blockchain’s state so it should be declared as view. Pure methods are the ones that don’t read or modify the blockchain’s state.addTwoNumbers answers the description of pure methods.

First Solidity Program: Hello World
The license identifier indicates the license of the file. 3. line shows the compiler version of the file. ^ means it can be compiled with 0.8.13 or newer versions. The contract is equivalent to class in other languages. All functions must indicate return types if it is returning something. Memory keyword will be discussed in future topics
