  1. What does the EVM do?
    EVM is executive program between Smart Contract program and CPU. Basically, it executes the program in the smart contract and gives it to CPU. We need EVM for security reason.
  2. What is the format of the instructions that the EVM can read?
    Byte format
  3. What is the relationship between the programming language Solidity and Bytecode?
    In order to create Bytecode, you need Solidity it is a programing language.
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Because the purpose of Bitcoin is to be a digital gold.
  5. What is a Turing Complete programming language?
    Turing complete program means you can program anything you want.

  1. What does the EVM do? It is a virtual machine, much like Java JVM, which interprets bytecode, this is what makes software portability possible. Also, the EVM separates the software development environment from the hardware\CPU, which is key to creating a hack-proof environment.
  2. What is the format of the instructions that the EVM can read? EVM reads Bytecode format instructions.
  3. What is the relationship between the programming language Solidity and Bytecode? Solidity is a compile-able programming language similar in structure to JavaScript. Solidity code is compiled into Bytecode.
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can? Bitcoin only has a scripting language that is not Turing complete, in other words it is limited in its functionality. This was done on purpose to make it more difficult to alter the Bitcoin blockchain.
  5. What is a Turing Complete programming language? A Turing complete language is a fully programmable language that enables control loops.

  1. The EVM makes executing code on network possible. It encapsulates smart contract code to prevent malicious activities.
  2. The format is bytecode.
  3. Solidity is a programming language that reads the inputs. A special application takes the Solidity code and compiles it down to bytecode. EVM will read the compiled inputs.
  4. Bitcoin cannot run the same code because it is static and limited to the capacity that Script programming provides. It is not turing complete.
  5. A turing complete language is dynamic and has ability to program loops.

  1. What does the EVM do?

The EVM is a virtual machine which is being run by every node on the Ethereum network. It translates bytecode (compiled from Solidity code) into CPU instructions in order to complete the tasks specified by the given piece of Solidity code.

  1. What is the format of the instructions that the EVM can read?

The EVM can read bytecode.

  1. What is the relationship between the programming language Solidity and Bytecode?

Solidity is compiled into bytecode.

  1. Why can’t Bitcoin run the same type of complex programs like Ethereum can?

Bitcoin’s programming language, ‘script’, is not a Turing Complete language and therefore can only be used to fulfill very simple operations.

  1. What is a Turing Complete programming language?

A Turing Complete language is one that can create programs to solve any computational problem which might require conditional execution based on inputs, RAM, ‘infinite’ memory etc.

  1. What does the EVM do?
    The EVM executes the instructions that have been programmed into a smart contract. It also serves to prevent malicious code from being run directly on the CPU of a network node.

  2. What is the format of the instructions that the EVM can read?
    The EVM reads the bytcode (as opposed to the source code itself) that results from the compilation of a smart contract.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is a language in which the developer may write a smart contract. The language itself is readable by the human eye. The source code (written in Solidity) must be compiled into machine-readable instructions in Bytecode, which is executed by the EVM.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin’s programming language - Script - is not Turing complete, but Solidity (an Ethereum programming language) is. As such, Bitcoin can only address a subset of the universe of problems which can be handled on the Ethereum blockchain.

  5. What is a Turing Complete programming language?
    A Turing Complete language is one capable of solving/addressing any conceivable problem. Conversely, one can pose problems that cannot be addressed by a non Turing Complete language.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is just a programming language, and you can compile the code from the programming language to Bytecode.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Because you can’t run certain statements such as a loop. Bitcoin can’t run these kinds of complex programs.

  1. EVM/The Ethereum virtual machine will check smart contract on malicious code before passing it on to the CPU of the node running the EVM

2.This means that every smart contract running inside the EVM has no access to the network, file system, or other processes running on the computer hosting the VM.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Bytecode is the code that can be read by the EVM so it’s not executed directly from the smart contract written in Solidity. Bytecode is a format created by compiling Solidity or Viper by the compiler.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    The script programming language is not Turing complete.
    It is limited to specific actions

  1. EVM stands for Ethereum virtual machine and it reads the instructions written on the smart contracts and then tells the CPU to execute them. Also it provides security to the smart contracts because if the CPU had direct access to the smart contracts, some people could create some contracts to use for bad purposes.

  2. Bytecode.

  3. Solidity is compiled into Bytecode.

  4. It’s programming language “Script” is not turing complete.

    You code in Solidity and the program is transalated into Bytecode for the EVP to read.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin is a not turing complete. It is limited to just executing simple programming instructions. Ethereum on the other hand can handle much more complex transactions such as smart contracts.

1.- What does the EVM do?
EVM executes Smart Contracts on the Ethereum Network

2.- What is the format of the instructions that the EVM can read?
The EVM runs a specific bytecode (say, EVM bytecode)

3.- What is the relationship between the programming language Solidity and Bytecode?
Developers write their Smart Contracts’ code in Solidity, then they compile it, which will give an EVM bytecode as an output, reflecting the instructions that were programmed, but in a machine-readable format.

4.- Why can’t Bitcoin run the same type of complex programs like Ethereum can?
Because Script (the programming language for Bitcoin) is not as powerful as Ethereum’s solidity, in terms that the first is not Turing Complete, while the second is.

5.- What is a Turing Complete programming language?
A programming language is considered Turing Complete if you can implement any possible algorithm on it.
