Homework on EVM

Ethereum 101
#3295

  1. EVM (ethereum virtual machine) reads the code from smart contracts on ethereum and instructs the CPU of the node that is running it to execute those instructions

  2. Bytecode

  3. Solidity is the format in which programmers design smart contracts. They look more like the languages we speak. Smart contracts written in slidity are converted to bytecode format for the EVM to read and execute

  4. Bitcoin programming language (Script) is not turing complete. It does not have functionality such as loops which allow for more complex functions needed for smart contracts

  5. Turing complete languages have the ability to solve any computational problem given the right time and memory

  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 has a compiler that transform Solidity code into byte code, EVM reads byte code.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Because the programming language of Bitcoin is Script, which is not Turing Complete and can’t solve all problems

  5. What is a Turing Complete programming language?
    It is a sophisticated programming language that can run loops and capable of developing any applications you want

  2. EVM reads formats within a sandbox environment.

  3. Solidity is the language used on the ethereum network and bytecode is used within the EVM. (I think?)

  4. Because bitcoin is non-turing complete.

  5. Turing complete means that you can program anything and also incudes action loops.

  1. Read the bytecode written by programming languages such as Solidity or Vyper and then execute it to the CPU of the entire network. It works as a layer so the bytecode scripts are not executed directly to the CPU in case there are some malicious events occur.
  2. Bytecode
  3. Solidity and other programming languages are compiled into bytecode so the EVM can execute the program.
  4. Because the Bitcoin program is non-Turing complete.
  5. A programming language is Turing complete if you can implement any possible algorithm with it.

  1. EVM reads instructions from Smart Contract and then pass it on to CPU for execution.
  2. EVM can read turning complete language, called Solidity.
  3. Solidity is compiled into EVM Bytecode, which is then running on Etherume nodes for execution.
  4. Because Bitcoin programming language Script is not Turing Complete for security reasons. With Script, you can do a limited amount of actions.
  5. Turing Complete programming language allows you to run loops, which means repeating the same action again and again. Programing Language is Turing Complete only when you can write every possible computable function in this language.

  1. The EVM exists on all Ethereum nodes and executes the smart contracts from the Ethereum blockchain.
  2. The EVM reads bytecode.
  3. Coding of smart contracts is done using the language Solidity which is then run through a compiler which translates it to bytecode which is able to be executed by a computer.
  4. Bitcoin uses a language call script which is very basic, unlike the turing complete language, Solidity, which is used by Ethereum. The reason for this is that Bitcoin did not want to bog down the blockchain, preferring instead to be more of digital gold than defi.
  5. A Turing complete programming language can basically code anything possible. It is not limited by design.

  3. The SC is written in Solidity by devs and then it is converted to byte code

  5. That anything you can think of, can be written and ran in that language

  1. What does the EVM do?
    Instead of 1 CPU, Ethereum is operating on a huge network of computers so there is no single CPU. And to make the execution of the smart contracts secure, Ethereum uses EVM. EVM makes it possible for us to execute code (small programs) on the network in a way that we are all in consensus about what the result should be.

  2. What is the format of the instructions that the EVM can read?
    Smart contracts have instructions and they will be in bytecode. Programers are using the programming language Solidity to get to the byte code.
    Solidity is a programing language like Java script. It is a turing complete language, which means that you can program anything you want. Ethereum uses Solidity compiler (a special app) that will take Solidity code (instructions and the logic you have given in the Solidity ) and compile it to byte code. The EVM only cares about the byte code and it executes the byte code.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Programers are using programming language Solidity to get to the byte code. Solidity is a programing language like Java script
    It is a turing complete language. Solidity compiler is (a special app) that will take Solidity code (instructions and the logic you have given in the Solidity )and compile it to byte code.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Because it uses script language and the script language is not turing complete. This means that it cant solve all problems and it is limited.

  5. What is a Turing Complete programming language?
    A turing complete language gives you the possibility to program anything you want. It is not limited by any features.

1 - EVM is te Ethereum Virtual Machine, which is an interface between the Ethereum protocol and the Node’s CPU.
2 - Byte code
3 - Solidity’s instructions are written in an understandable language, which is then run through a compiler, that produces byte code instructions readable and executable by the EVM
4 - Bitcoin’s programming language is Script, which is not Turing complete, and allows only very limited programming. It was a conscious decision, to avoid slowing down the network with the extra information that it would have needed to store.
5 -Turing complete languages have the ability to solve any computational problem given the right time and memory

  2. The evm reads byte code.

  3. The relationship between solidity and byte code happens when a smart contract is created and the complier creates the byte code that can now be executed on evm.

  4. Bitcoin can’t run smart contracts because it run a language called scripts, scripts can only perform very simple task like multi sig.

  5. Turing complete programming language allows you program code to perform complex functions on such as looping.

  1. What does the EVM do?

EVM allows for Solidity code to be executed on the blockchain in form of Smart Contracts.

  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?

Smart contracts written in Solidity are put through a compiler to be shown in EVN bytecode, which is then read by EVM and executed.

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

Because Script (the language in which you can write contracts on BTC blockchain) is not TC (Turing Complete), so It has much less possibilities and functionality.

  1. What is a Turing Complete programming language?
    A programming language which can preform higher level actions and passes the Turing Machine test. It is a programming language which has the ability to be computationally universal - this means that this system is able to recognize or decide other data-manipulation rule sets.

  1. What does the EVM do?
    EVM is the Ethereum virtual machine that adds another level of performance by making it possible to execute code. The EVM is available on each node on the network, it interprets and executes smart contracts.

  2. What is the format of the instructions that the EVM can read?
    The EVM itself interprets and executes smart contracts by which it prevents the CPU to directly come into communication with it. This is an enhancement of security for the network.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is the programing language used to create smart contracts that then need to be converted into byte code that is what the EVM uses in order to interpret and execute smart contracts.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin cannot run the same type of complex programs like the Eth network can because it is not Turing complete.

  5. What is a Turing Complete programming language?
    It is a language capable of performing various complex operations.
