  1. What does the EVM do?

EVM is a program, run on every ethereum node. It can execute the smart contracts that are written in solidity language and compiled into bytecode.

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

EVM can read Bytecode

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

Solidity program has to be compiled, by the use of compiler, into bytecode, to be readable by EVM.

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

Because bitcoins’s programming language “script” is not turn complete, and doesn’t allow every possible program to be written on top of it.
Possibilities of Ethereum’s projects, using turing complete Solidity are limitless. But that comes with a cost with possible issues with scalability, over expansion of nework’s data size and possibility of spamming the network, by abusing the function of loops. This issue was solved by introduction of fees on the processes.
On the other hand, bitcoin’s “script” is not turing complete. That means it is limited, simple, network is extremely secure, spam resistant and more suitable to be used as a transfer of value, in opposite of ethereum platform’s infinite possibility to realise every idea, no matter how abstract.

  1. What is a Turing Complete programming language?

Turing complete programming language can solve any kind of algorithm, so any kind of application can be written, using it. Expression “turing complete”, comes from theoretical example, represented by Alan Turing. That is a machine, that can calculate any mathematical problem.
One feature of turing complete language is capability of making loops, that is multiplication of processes. Solidity can produce loops, bitcoin’s script can’t.

Question #1 - What does the EVM do?
It’s a technology that allows to execute code on the Ethereum Network/Blockchain in such a way that we are all in consensus about what the result should be.

Question #2 What is the format of the instructions that the EVM can read?
It’s the information inside the byte code.

Question #3 What is the relationship between the programming language Solidity and Bytecode?

Solidity program has to be compiled, by the use of compiler, into bytecode then the EVM can read it from the bytecode - also there is a new programming language called Viper that EVM can also read no problem because code from Viper gets compiled into bytecode as well.

Question #4 Why can’t Bitcoin run the same type of complex programs like Ethereum can?

Because Bitcoin uses programming language called Script that is focued on simplicity transaction aspect of the Bitcoin blockchain(network) so that it is not prone to security issues and very stable.

Ethereum has to solve scalability issues.

Question #4 What is a Turing Complete programming language?

It means that the programming language can run complex code and use it to tell software to do things thousands of times and it can do it. Bitcoin is not Turing complete and it cannot do loops like Solidity. Thanks to that Bitcoin network is not spammed and works well as a store of value.

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

Bitcoin network can’t run the same type of complex programs because the Bitcoin Script programming language is not Turing Complete programming language.

  1. What does the EVM do?
    The EVM reads the instructions in the smart contract and tells the CPU what to do. It prevents the smart contract from giving commands directly to the CPU.

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

  3. What is the relationship between the programming language Solidity and Bytecode?
    The code of the smart contract is created using the programming language solidity (can also be another programming language like Viper). This code is then transformed into byte code by a compiler, because the EVM doesn’t care in which programming language the code was written, it only reads the byte code.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    The programming language on bitcoin (Script) is not tuning complete. For example, it doesn’t allow the use of loops in your code.

  5. What is a Turing Complete programming language?
    A programming language that allows you to program anything.

  1. EVM is an environment responsible for execution of smart contracts. It executes bytecode compiled from higher level languages.
  2. It is in bytecode.
  3. Smart contracts first written on Solidity, then compiled (translated) into bytecode and become understandable for execution by EVM.
  4. Because, Bitcoin’s script language is not Turing complete. I guess it’s hard to implement sophisticated logic or even simple loops, which is pretty useful and standard feature in most commonly known higher level programming languages.
  5. Well, it is a programming language that can run any program that a Turing machine can run given enough time and memory. In other words, if you can write a program that will run on a Turing machine, then you can theoretically write the same program using Turing complete language.

What does the EVM do? - It reads in a protected manner byte-code from the network of nodes on which the Etherium Virtual machine is constructed and translates that into instructions about what the Smart Contract dictates should be done.

What is the format of the instructions that the EVM can read? - It reads the byte code format derived from Smart Contracts.

What is the relationship between the programming language Solidity and Bytecode? - Solidity is a Turing Complete language made specifically for writing the Smart Contracts in Etherium which are converted to byte code instructions suitable for any EVM to read and relay to the CPU it is associated with.

Why can’t Bitcoin run the same type of complex programs like Ethereum can? - For security reasons, Script - the language used to program Bitcoin, is kept simple and is therefore not Turing complete, specifically it allows no loops, only primitive constructions.

What is a Turing Complete programming language? - It is a language with no limitations on what can be constructed.

  1. It reads logic (solidity is the language that’s used) from the smart contracts and executes that code.

  2. EVM looks at instructions from the smart contract (bytecode) and will tell the CPU (node) of the pc what to do.

  3. Solidity is the user facing language which we understand and it compiles the information in bytecode into the smart contract

  4. Because it is not Touring complete it can’t solve all problems it has script, in theory ETH can solve all problems as it is touring complete
