  1. What does the EVM do?
    *EVM, Ethereum Virtual Machine, is the network of computers running the software which makes up the function of the Ethereum network. The computers running EVM software are, in effect, the hardware of the network, and the EVM program is the software.
    They communicate with each other; each carries out the instructions and compare with other comps, which will verify each others’ results.

  2. What is the format of the instructions that the EVM can read?
    *EVM byte code

  3. What is the relationship between the programming language Solidity and Bytecode?
    *Programmers use Solidity or Viper to create the smart contract. Then those programs convert their instructions through a “compiler” into EVM byte code, which is the actual language of the smart contract.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    *Its language, Script, is not “turing complete”.
    It is able to carry out only very simple commands.

  5. What is a Turing Complete programming language?
    It is as flexible as its programmer can imagine… it can be made to carry out pretty much any computer task.
    One important advance it has is to carry out loops-- performing commands repetitively as needed.

What does the EVM do?

It runs bytecode on the Ethereum network. Meaning it executes the instructions in the smart contract deployed on Ethereum.

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

Bytecode

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

In solidity, you write in “English”, but solidity has a complier that turn that language into bytecode

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

It is not turning complete. Can not do loops etc.

  1. What is a Turing Complete programming language?

A language that can do more complex logics. You can in theory build anything on it

1.) its the part between the blockchain and the CPU from the pc. He secure that the smart contract not get acces to the CPU and he makes the consensus on the blockchain.

2.) bytecode

3.) The bytecode is for the EVM, and to write a bytecode there you need solidity.

4.) Bitcoin ist not turing complete, what means there you can programming litte thing on it but not even that much that you can do with solidity. Bitcoins programming language is script and this is really limited and there are no loops.

5.) On an turing complete blockchain there you can programming everything you want.

  1. What does the EVM do? -> it is a virtual machine that runs on each Ethereum node and executes smart contract bytecode
  2. What is the format of the instructions that the EVM can read? -> Bytecode
  3. What is the relationship between the programming language Solidity and Bytecode? -> Solidity is a human readable programming language that is used as a tool to write smart contracts. The Solidity source code gets compiled into executable bytecode through the viper compiler.
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can? -> Even though bitcoin also has a scripting language called scrypt, it cannot execute complex contracts, because it is intentionally not a Turing complete language. This is for security reasons.
  5. What is a Turing Complete programming language? This is a rather complicated thing to explain but as a simplification it is a programming language that allows loops.

  1. EVM reads the code and executes the commands.
  2. The format that EVM can read is Bytecode.
  3. Solidity can be used to write for example smart contracts, than you use a compiler to transform what you programmed in Solidity into Bytecode that can be processed by the EVM.
  4. Bitcoin can’t run the same type of Complex programs like Ethereum, because it uses a not Turing complete language, but Ethereum does. Also Ethereum uses the EVM to execute these programs and to enhance the safety of the system.
  5. A Turing Complete programming language means you can program anything with no limitation.

  1. The EVM is the operating software that allows smart contract to run.

  2. The EVM Reads Bytecode.

  3. Bytecode and solidity are just different languages. Humans understand solididy, Computers understand bytecode. an compiler is a translator.

  4. Bitcoin cant run complex programs because it is locked down for security.

  5. Turing complete is a programming language that has no borders or restrictions. you can program anything.

  1. EVM runs the smart contracs and exacute the instructions.
  2. EVM reads Bytecode.
  3. Solidity transforms the smartcontrack into bytecode so the computer could read it.
  4. Bitcoins P.L. is script and it is not turing complete witch means you cannot do many things with it.
  5. With it you can programe anything and it can loop in many sitiuations without the need of a person to it.

Bitcoin is not Turing complete, meaning that it lacks the code required to execute complex programs.

5. What is a Turing Complete programming language?
A Turing complete programming language is one that is programmed to be able to perform any task you want.
