  1. An Ethereum Virtual Machine allows developer and programmers to run the code which changes from Solidity to Byte code. The EVM is also able to run the code/ smart contract and to get consensus from the entire network.
  2. The EVM operates in a sandbox environment which means that it runs in an isolated environment which means that it is protected and safe from malicious entities.
  3. Solidity is the initial programming language used on the Ethereum network, but solidity then turns the code into Byte format to be executed by the EVM.
  4. BTC can not run the same type of complex programs like Ethereum because the language of BTC (Script) is not a Turing Complete Language.
  5. A Turing complete programming language is essentially a programming language without limits. A language where by in theory you can programme any conditions that you want.

  1. EVM is a script that all computer s in the ethereum network run on top of their CPU. It executes actions that are sent as bytes via the CPU without allowing for other auctions that break away from the bytes intention.
  2. They are Script language that gets compiled into byte code.
  3. Solidity is the programming language that is used to write and develop smart contracts. That script then gets compiled into a byte that the EVM with then read and instruct the CPU specifically what to do based on the actions in the script.
  4. The language that bitcoin uses is not the same as Ethereum, so with that said, its limitations are the types of actions able to be performed from the language itself.
  5. A Turing complete language is a coding language that allows free reign of any actions that could be performed using the code itself.

The Ethereum Virtual Machine runs on top of a CPU. It reads and executes smart contracts.

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

What is the relationship between the programming language Solidity and Bytecode?
Solidity is a ‘compiler’ to read and write Bytecode.

Why can’t Bitcoin run the same type of complex programs like Ethereum can?
Bitcoin uses Script as a programming language, which is not a Turing complete code.

What is a Turing Complete programming language?
A language that in theory can program anything you like such as Solidity

  • What does the EVM do?
    -EVM is an application running on all of the nodes and it executing the smart contract and then gives instruction to the CPU .
  • What is the format of the instructions that the EVM can read?
    -EVM reads Byte Code
  • What is the relationship between the programming language Solidity and Bytecode?
    -Solidity is the programming language of smart conctract . EVM decodes solidity instructions to execute them in Bytecode
  • Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    -Because Bitcoin is using the programming language Script , which is non turing language . It means it can not solve all problems that it may need to solve.
  • What is a Turing Complete programming language?
    -A turing complete programming language means that you can in theory programme anything you want. Turing complete also allows you to program loops.

The EVM runs the smart contracts for Ethereum. This ensures that all nodes running the contracts get the same results no matter their hardware or software, and that they can validate them in the same conditions. It also prevents malicious contracts from having access to the CPU and the rest of the components of the computer where the EVM is being run.

The EVM reads the instructions in Bytecode, which is a low-level computer language, which is easier to read for machines, but harder to read for humans.

Solidity, on the other hand, is a high-level computer language, which is way easier to handle and understand for humans. This way, users program smart contracts in Solidity, which then gets translated into Bytecode for the EVM to execute.

Bitcoin cannot run the same type of complex programs that Ethereum can, because Script, its language, is not Turing-complete, which means it is more limited in its capabilities. A Turing-complete language is a language which can simulate the traits of another general-purpose full-fledged computer language.

What does the EVM do? The EVM provides a layer of abstraction (kind of like a middle man) between the executing code and the executing machine. The EVM provides security from Denial Of Service attacks and provides execution of untrusted code. It is a runtime or sandboxed environment.

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

What is the relationship between the programming language Solidity and Bytecode?
Smart contracts are written in Solidity and are then compiled into Bytecode witch the EVM reads.

Why can’t Bitcoin run the same type of complex programs like Ethereum can?
Unlike Ethereum, Bitcoin can not run the same complex programs because it is not a Turing complete language.

Turing Completeness refers to the a programming language that can be used to simulate any Turing machine. This basically means that it is capable of performing complex operations.
