How Gas Works?
GasGas is the measure of cost to perform an operation in the blockchain. This relative to the computational cost of the specific operation. Ethereum Docs gives us the list of opcodes and their respective gas cost.Ethereum Docs OPCODE tableThough the gas ‘cost’ is fixed, the actual ‘price’ of gas(measured in Gwei) is ever-changing. This is often compared with the analogy of a car and gasoline price. Every car has a ‘fixed’ cost for the amount of gas that is needed to run from point A to B. How...

Blockchain Interview Questions and Answers Part-1
What is the difference between private, internal, public, and external functions?Private functions are only accessible to the contract that defines it. Internal functions are only accessible to the contract that defines it and any child contracts that inherit it. External functions are only accessible externally by other contracts and are not visible inside the contracts that define them. External uses less gas than public. Public functions are accessible to the contract that defines it and t...
