  1. What does the EVM do?
    The EVM (Ethereum Vrtual Machine) is a program that runs on every ethereum node. To ensure that each machine is able to run the same code, in the same way. The code is encapsulated within the EVM. The EVM can run and execute smart contracts. It will use Solididty to read the smart contract, compile it to Bytecode and instruct the CPU’s of the various nodes. It will reach a result. All the nodes need to reach the same result to give consensus.

  2. What is the format of the instructions that the EVM can read?
    The EVM reads Bytecode.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity reads the smart contract and compiles it into Bytecode. The EVM runs Bytecode.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin has a scripting language called ‘Script’. It is not a Turing Complete language (it is Turing Incomplete) and has limited functionality. It will not allow more complex operations such as iteration (loops).

  5. What is a Turing Complete programming language?
    A Turing Complete language is capable of solving any mathematical problem or task as long as it has the correct instructions, time and processing power. It is capable of greater complexity than a Turing Incomplete language like the one Bitcoin uses.

  1. the EVM is in charge of delegating tasks to the resources (CPU, GPU, RAM) of the device running the ethereum node. The bytecode of the smart contracts is executed by the EVM.
  2. it’s bytecode. Machine readable code that is generated by the (solidity) compiler.
  3. Solidity gets compiled to bytecode by the compiler.
  4. because the language of bitcoin (script) is very primitive (turing incomplete)
  5. A turing complete programming language is theoretically (if there were infinite hardware resources) capable of solving anything.

  1. What does the EVM do?
  • reads all the instructions in a smart contract and calculates them. communicates with node and instruct it’s CPU. EVM is in between smart contract and CPU and will ensure that nothing malicious happens because code is not running directly on CPU.
  1. What is the format of the instructions that the EVM can read?
  • EVM bytecode
  1. What is the relationship between the programming language Solidity and Bytecode?
  • it is possible to compile solidity into bytecode which is used by EVM
  1. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
  • BTC programming language is script, it is not possible to run smart contracts on this.
  • script is not turing complete
  1. What is a Turing Complete programming language?
  • turing complete programming languages have “loops”
  • loops allow programmers to tell software to do one thing several times
  • (“you can program anything you want” - in theory - practically limited by scalability issues)

  1. What does the EVM do?
    It reads the Byte Code and tells the CPU to execute the terms of smart contracts. It is also located between the CPU and the smart contracts and acts as a security layer for the network.
  2. What is the format of the instructions that the EVM can read?
    EVM reads the Bytecode. Current Ethereum programming language is Solidity and you need a compiler to transform that into Bytecode readable for the EVM.
  3. What is the relationship between the programming language Solidity and Bytecode?
    The smart contracts are written in Solidity. The Solidity compiler takes code and compiles logic and instructions into Bytecode, making it readable for the EVM.
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin programming language is Scrypt, which is not Turing complete. The smart contract functionality is limited.
  5. What is a Turing Complete programming language?
    Turing complete languages contain loops which let programs execute a set of functions once and after looping back to perform the set of functions again.

  1. All code written on the ethereum network needs to og through the EVM first. The EVM is «above» your computers hardware and will tell all the computers (nodes) CPUs what code they are supposed to execute. The EVM “deploys” smart contracts on the ethereum network.
  2. The format of the instructions the EVM can read is byte code.
  3. The realationship between solidity and byte code is that solidity code can be compiled into byte code
  4. Bitcoin cant run the same typem of complex programs as ethereum because they dont have a turing complete language and the language they use is called script. If bitcoin used a turing complete language like solidity, people could create loops with the code which would create a lot of spam on the blockchain causing it to take up a lot more space.
  5. A turing complete language is a coding language where you can solve all problems through code, it is not limited.
