Ethereum 101
#3616
  1. EVM is isolated environment present in each node which can run the smart contracts.
  2. EVM can read EVM Bytecode which is the output of compiled Solidity or Vyper code (at least for ethereum).
  3. Bytecode is a compiled version of solidity code.
  4. Because Bitcoin language (Script) is very limited due to lack of loops.
  5. Turing complete programming language is the language which allows to write the functionality as in other popular languages and has no limits on set of things.
#3617
  1. What does the EVM do?
    The Ethereum Virtual Machine (EVM) sits on top of a node CPU and reads smart contracts then instructs the CPU what to do.
  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 (and Viper) are programming languages that compile smart contracts into Bytecode.
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    There is nothing, like the EVM, to interpret and execute smart contract code.
  5. What is a Turing Complete programming language?
    A language that supports complex (i.e. loops) structures.

1- EVM executes the smart contracts and tell CPU what to do. Also EVM incapsulate the smart contracts to insure that nothing malicious happen to your computer.

2- Byte code compiled from Solidity language.

3- Solidity is a programming language which is like english, but your CPU does not understand it, so it needs to converted to a byte code.

4- Bitcoin’s programming language ‘script’ is not a turing complete language, so what you can do is very limited.

5- Turing complete programming language can solve any mathematical problem, so anything is possible to write as a program in theory.

EMV is code running on all ethereum networks encapsulates the code to protect it, and shares it with the entire network.

Its byte code that’s translated to solidity

Byte code is translated into solidity so the EMV can read it

Bitcoin is not Turing complete so it can’t do loops and makes it hard to process lots of computations

Turing complete has loops that allows the software to do many things many time over and over again allowing the program to be more sophisticated

  1. EVM reads and executes the smart contracts stored on the blockchain using the nodes’ resources.
  2. EVMs can read bytecode instructions compiled by Solidity or Viper.
  3. Bytecode is the compiled version of the contract. Solidity is the programming language.
  4. A turing complete language is able to execute complex tasks and functions, practically no limitations on what could be achieved with that language.

1- Read and execute smart contract.

2- Byte code.

3- Smart contracts are written in solidity and then compiled in EVM byte code.

4- Because it is not turing complete.

5- It allows loops.

  1. EVM is an application that enables the execution of codes on the smart contract.
  2. EVM reads in Byte code.
  3. Solidity is used to interpret Byte code.
  4. Bitcoin uses Script Program language and is a Turing Incomplete language
  5. A Turing Complete Language is a language that can solve multiple maths problems and can be used to created multiple program languages
#3625

The EVM (Ethereum Virtual Machine) runs on every node in the network, and reads the smart contract instructions to the CPU without compromising sensitive information. It also prevents malicious code from affecting the node by running isolated from the node OS. (Sandbox environment)

The format of instructions the EVM reads is Bytecode.

Solidity is the programming language within the smart contracts. A ‘compiler’ translates that information into Bytecode, which can then be read by the EVM.

Bitcoin can’t run the same type of complex programs because Script is not a turing complete programming language.

A turing complete programming language can make anything happen. They include loops, which make them far more adaptable.

  1. What does the EVM do?
    Runs smart contracts. Reads smart contracts byte code
  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?
    Solidity gets compiled into byte code which gets read by EVM
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin doesn’t turing complete language.
  5. What is a Turing Complete programming language?
    A fully fledged language that can run complicated logic and syntaxes like loops.
#3627
  1. The EVM executes code for each node. It acts a “middle man” between the smart contract bytecode and CPU.
  2. Bytecode
  3. Solidity is a high-level programming language and bytecode is the low-level language which it is compiled to.
  4. Bitcoin lacks Turing completeness; for example, it cannot run loops.
  5. A Turing Complete programming language is very flexible and can run any program
#3628

  1. The EVM is a program that runs on every nodes computer which is able to compile smart contracts into byte code. The EVM utilises the node’s CPU, whilst containing the execution of the smart contract to the EVM.

  2. The EVM will compile solidity into byte code and execute the smart contract in byte code.

  3. Solidity is how humans program smart contracts and bytecode is how the Ethereum Virtual Machine handles it. Essentially, Solidity is the English speaking version of smart contracts, and bytecode is the computer language version of smart contracts. The EVM must first compile solidity into byte code however.

  4. The bitcoin community decided against Turing-complete programs on the network due to block bloat, which would result in scalability issues. Since smart contracts are significantly larger and essentially limitless, people could spam the network and cause congestion and high transaction costs.

  5. A Turing Complete programming language is one which has no bounds on the programmability of events. If the programmer can think it, they can code it with Turing Complete programming languages. A programming language which is not Turing Complete like bitcoin has limitations, which is not necessarily a bad thing. A non Turing Complete programming language usually exists for a specific role. There a many things a programmer could not program on a non Turing Complete programming language.

  1. Its an app on that runs on each node of the ethereum network that reads smart contract and that communicate the operations to be done directly with the cpu. We can see it as an interface between Smart contract and CPU
  2. byte code
  3. It is compiled from solidity into bytecode.
  4. Because the programing language of BTC (script) is not turing complete.
  5. A programing language that allows to develop anything. And a programating language that feature the loop function.

  1. EVM defines the frules for computing a new valid state from block to blcok. It exists as one ententy mantained by thousands of connected computers running an Ethereum client.

  2. Smart contract languages like solidity, vyper, bamboo, serpent (deprecated) and mutan (deprecated) are compiled to low-level machine instructions (opcodes). There are 140 unique opcodes that allow EVM to be Turing-coplete.

  3. When we compile solidity with solc compiler, it is translated into bytecode, somethin the EVM can understand.

  4. Because bitcoin isn’t touring complete.

  5. It means that it facilites the computation of any mathematical problem, given enough resources.

1/ EVM (ETH virtual machine) it executes codes on the network, it reads the instructions and tells the CPU to execute them
2/ byte code
3/ it is the code that Solidity can read. It uses a compiler ,special application, that reads bytecode
4/Because BTC uses Scrip and it is not turing complete while ETH has a turing complete
5/ It’s ETH :slight_smile: it’s a programme that can solve all problems, is not limited. It can programme, script and also gives the developers the oportunity to create. A turing complete language, has loops , a very important figure that allows to tell software to do one thing, several times.

  1. What does the EVM do?
    –> EVM is the middleware between the original bytecode on the Ethereum blockchain and the processing CPUs

  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?
    –> interpreter: Solidity makes bytecode possible to process by the CPU/GPU

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    –> Bitcoin’s Script language is limited as it’s not touring complete (TC) and therefore can only solve complex iterations manually.

  5. What is a Turing Complete programming language?
    –> One that given enough time can solve every problem through iterations
