#3055
  1. What does the EVM do? EVM is an app that is running on each node and that is capable of reading the smart contracts and executing their instructions, it is capable of reading the Solidity language after it is compiled in byte code. EVM is also adding a level of security because all nodes need to be in a consensus that the requirements in the smart contract are satisfied.
  2. What is the format of the instructions that the EVM can read? as written above, the code is written in solidity which is subsequently compiled in byte code for the EVM to be able to read it
  3. What is the relationship between the programming language Solidity and Bytecode? explained with previous question
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can? Because Bitcoin’s language (script) is more basic and does not have the loops capability which is deliberate as not to cause too much congestion in the blockchain. Bitcoin is non-touring complete.
  5. What is a Turing Complete programming language? It has the loops capability which allows for an instruction to be repeated multiple times as opposed to creating the repetitions one by one.

  1. The Ethereum Virtual Machine (EVM) processes byte code instructions on the smart contract and ensures consensus of the contract across the network.

  2. The instructions / code is programmed using the Solidity language before being compiled into byte code, which the EVM then reads and processes.

  3. Solidity is the language used by the developer to create the instructions and byte code is the language read by the EVM.

  4. Bitcoin uses a language called Script which does not have Turing Complete capabilities. Meaning it can’t run loops like solidity can. This is to ensure less overhead in the Bitcoin blockchain and mitigate against potential bottleneck / spamming programmes being created.

  5. A Turing Complete language is one whereby loops can be created. I.e. more complex programming for more depth of instructions.

  1. What does the EVM do?

The EVM is a machine that runs bytecode instructions to transform the system state from one state to another. It sends the instruction via the EVM to the CPU The EVM is a Turing-complete machine but is limited by the amount of gas that is required to run any instruction.

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

Once the code is written, it is compiled into bytecode that’s understandable by the EVM.

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

Code for smart contracts in Ethereum is written in high-level languages such as, Solidity, or Vyper, and is converted into the bytecode that the EVM understands for it to be executed. Once the code is written, it is compiled into bytecode that’s understandable by the EVM using the Solidity compiler

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

The “Script” language for the bitcoin blockchain is not Turing complete like the EVM and can only run very simple commands.

  1. What is a Turing Complete programming language?

A Turing complete language means that it can perform any computation. It is named after Alan Turing, who developed the idea of a Turing machine that can run any algorithm however complex. Turing complete languages need loops and branching capability to perform complex computations.

  1. What does the EVM do?
    Provides a security, reads and executes smart contracts while using the computing power of the network.

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

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity has a compiler that creates the bytecode the EVM reads.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    The programming language will not allow it but in a bigger picture, it is important to keep the type of programs (transactions) occuring on bitcoin to “pure” transactions - not ones that will strain the network and result in increased blockchain unnecessarily.
    The desire is to keep bitcoin as money, digital gold, a store of value.

  5. What is a Turing Complete programming language?
    One that can solve complex problems and can be used to program almost anything you can think of, not limited the way Bitcoin’s Script programming language is.
    Has Loops - a feature that allows you to tell the computer to do something several times.

EVM Homework

  1. What does the EVM do?

EVM - Ethereum Virtual Machine is basically a program that can execute smart contracts, its essentially a program running isolated within a pc or each node, all nodes have the EVM running on top of their own CPU, making it safe for smart contracts to be executed in an encapsulated and safe envoironment, thus without making the main machine or CPU vulnerable to possible bad programs or code

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

Smart contracts are written in whats called byte code, using a program called solidity. Solidity is a program similar to Java script

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

Solidity is a language like English, you use this to write your program. It has a compiler which takes your solidity program and turns it into byte code, this can then be read by the EVM. New languages can be added with their own compiler to turn it to byte code for the EVM.

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

Bitcoin can’t run complex programs like Ethereum, it can do simple small programs but it is very limited as the script in bitcoin is not Turing Complete.

  1. What is a Turing Complete programming language?

A Turing Complete language can solve complex problems, it can be programmed in any way you can think. It has something called loops. This is a feature of the language that allows the programmer to tell the software to do one thing several times.

  1. What does the EVM do?

EVM runs on all of the Ethereum nodes and it is used to run the byte code.

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

The byte code.

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

You write the smart contract code in Solidity, then it is converted to byte code so that the EVM can run it.

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

The Bitcoin programming script is not Turing complete. The developers purposefully limited it this way so that the system wouldn’t be spammed and to increase security.

  1. What is a Turing Complete programming language?

When a programming language is Turing Complete it means that you have a lot more options when programming, like loops. Examples of this are Solidity and Viper.

  1. EVM reads :nerd_face: the byte code from smart contract :page_facing_up: and runs on the Ethereum nodes. EVM also prevents the execution of malicious :female_detective: code to the entire network, because EVM encapsulates :fishing_pole_and_fish: the contract for verification.
  2. Byte code :currency_exchange:
  3. EVM is a virtual machine placed between the operating system :file_cabinet: and the application :mag: layer to reduce dependency on the operating system. EVM bytecode is a low-level :walking_man::walking_woman: programming language composed of a high-level :running_man: :running_woman: programming language such as Solidity. EMV bytecode is an executable code :receipt: on EVM, requiring smart contract code written in Solidity to be compiled :next_track_button: into EVM bytecode in order to run.
  4. BTC program :receipt: has limited script functionality :warning: that is incomplete, so that the execution of byte code in more complex programs cannot make loops to ensure completeness.
    (The side effects in storage of states and amount of instructions offered, which have a major impact on blockchain size and network usage, meant that the BTC community did not want to deviate from their BTC vision as digital money / gold.)
  5. Turing completeness :white_check_mark: is a concept from theoretical computer science :man_student:. It tells you how powerful :mechanical_arm: a programming language is. Not in terms of performance or maintainability or how rich its ecosystem is. A programming language is Turing complete :white_check_mark: if you can implement any possible algorithm (with infinite :infinity: loops to control how long a loop :repeat: runs from within the loop :repeat: itself).
