Homework on EVM

Ethereum 101
#3195

  1. The EVM runs on every node and helps all nodes reach consensus. It reads smart contracts and makes sure they are valid before it tells the CPU what to do.

  2. Bytecode

  3. Code is written in Solidity and then compiled into Bytecode.

  4. Bitcoin is not Turing Complete, meaning that it cannot solve complex problems. It is only made for finance. Ethereum is Turing complete and has no limits and can also use loops to execute a contract more than once.

  5. See 4

  1. What does the EVM do?
    Take information from a program and execute that programs code. once done it pass the information to each individual computer that is in the Ethereum Network and complete the consensus process. Acting as a middleman between network and smart contract
  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?
    programing language provides code compiled by a compiler into bytecode
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin’s code is not “True and complete” bitcoin developers chose to only allow script language limiting its problem solving capability and its exposure to spamming
  5. What is a Turing Complete programming language?
    loops can be programed and pretty much anything else you can think of

  2. Byte Code format.

  3. Solidity>>>Compiler >>>Byte Code.

  4. Because it uses a simple programming which cannot do complex code and also not Turing Complete.

  5. It means that it has no limitation.

  1. What does the EVM do?
    -EVM will process the smart contracts through its channels to every computer on the Eth. network, think of it as a bridge between the two.

  2. What is the format of the instructions that the EVM can read?
    -EVM will work with bytecode.

  3. What is the relationship between the programming language Solidity and Bytecode?
    -The bytecode that the EVM will use comes from Solidity language that was converted to bytecode.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    BTC is not turing complete. Its functions and executions are quite limited.

  5. What is a Turing Complete programming language?
    It makes it possible to implement a very wide variety of executable functions.

  1. Ethereum is an appication that operates on top of the existing hardware on the ethereum network and that allows for the execution of smart contracts. It reads the smart contract and tells the cpu what to do so that the conditions of the smat contract can be met. It makes sure that all the EVMs on the network reach a consensus about the smart contract because only then can the contract be executed.

  2. EVM byte code

  3. Solidity is the programming language that is used to get to the bytecode

  4. Because bitcoin has a very simple programming language called script which does not allow for the use and execution of smart contracts

  5. It is a language that makes everything programmable.

  1. EVM is code that can read/execute smart contracts. It is a layer on top of the CPU. EVM executes first and tells each individual CUP what to do.

  2. It uses Solidity via bytecode to execute.

  3. Bytecode is the code or instructions.

  4. BTC uses Script. It is very primitive code and does not allow for more complicated functions. TCL (Turing Complete Language) Loops allows for more complexity.

  5. Loops tell the software one time to before a function over and over.

  1. EVM is the application that should be run on all the nodes in the network and it is executing the smart contracts - then the instructions are passed to CPU.
  2. The format that EVM can read is byte code.
  3. Solidity compiles the Bytecode so that EVM could read the instructions.
  4. Bitcoin cannot run the same type of complex program because the programming language used (script) is not turing complete.
  5. A turing complete programming language can perform any set of given instructions, it does not have limitations.

  1. What does the EVM do?
    Ethereum Virtual Machine runs on top of the existing software it uses CPU and other resources to read and execute smart contracts. It tells the CPU what to do. It also ensures that nothing malicious happens.

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

  3. What is the relationship between the programming language Solidity and Bytecode?
    Bytecode is compiled from Solidity using Compiler.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Because Bitcoin is using Script which is not Turing Complete.

  5. What is a Turing Complete programming language?
    Programming language that can theoretically solve any task possible. TC language also has a feature called Loops which allows you to tell the software to do a certain task x times.

  1. EVM is a piece of code that runs on top of the hardware in each node in the Ethereum network. It reads and execute smart contracts.
  2. Reads byte code.
  3. Solidity is the language in which smart contracts are written in, it is then composed into bytecode.
  4. Because Bitcoin uses “script” language - which is not Turing Complete, meaning it cannot program anything you want.
  5. Turing Complete means you can program anything you want. This also allows loops in smart contracts, without automatic loops you’d have to code each loop manually instruction by instruction.

  1. An EVM is responsible for executing the byte code from a smart contract. This helps achieve consensus on the blockchain, as all nodes must individually validate the smart contract instructions.

  2. Bytecode

  3. Solidity is the programming language used for development, which is converted into byte code through a compiler, allowing the programmed instructions to be executed in the smart contract

  4. Not Turing complete and therefore not easily programmable

  5. Can programme any application

  1. What does the EVM do?
    EVM (Ethereum virtual machine) is middle step between smart contract and CPU. It reads smart contract (instructions) and deploy it to CPU to execute it. EVM is application that runs on all nodes on ETH network.

    Byte code
  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is Ethereum smart contract language used for programing. It is easier to for people to understand. It is then converted to Bytecode through compiler so the EVM can read and execute it.
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Scrypt (Bitcoin language) It is not turing complete language and therefore you can not program anything.
  5. What is a Turing Complete programming language?
    It is language that can read and execute all codes/applications. You can program anything, also loops…
