What does the EVM do?
The Etherium Virtual Machine is the intermediary between the Smart Contract and the CPU. Its main purpose is to provide security and ensure that nothing malicious happens to the CPU’s executing the contract (program code). EVM protects the nodes and network vulnerability. -
What is the format of the instructions that the EVM can read?
The EVM reads Solidity programming code in byte code -
What is the relationship between the programming language Solidity and Bytecode?
Solidity supports the programmer language (similar to English or Java Script) whereas bytecode is the actual computer program language. -
Why can’t Bitcoin run the same type of complex programs like Ethereum can?
Bitcoin is not turing complete, meaning that it has limited functionality and therefore cannot solve all problems (for example programming cannot execute loops). -
What is a Turing complete programming language?
In contrast, Etherium is turing complete meaning that it has unlimited problem solving capabilities (it can execute loops) allowing the programmer to execute the same task over and over.
-
EVM (Ethereum Virtual Machine) is a part of nodes in network and reads and executes the Bytecode (instead of CPU). Bytecode is converted from solidity code, in which are smart contracts written.
-
Bytecode
-
Solidity is converted into Bytecode so EVM can read it.
-
Because Bitcoin uses programming language called Scrypt, which is very limited (it is not so called Turing complete). Instead Ethereum runs on Solidity (or Bytecode) which is in theory turing complete.
-
Turing complete language enables scalability and dynamic environment.
- What does the EVM do?
EVM maintain state, create environment to run start contracts, verify transactions.
- What is the format of the instructions that the EVM can read?
EVM-bytecode, a computer language.
- What is the relationship between the programming language Solidity and Bytecode?

-
Bitcoin programming language Script is NOT Turing complete, while Solidity IS Turing complete. That means we can have smart contracts on Ethereum but not on Bitcoin.
-
One that could, in theory, be used to solve any computation problem.
1- The EVM is an application that acts as an intermediary between the node’s hardware layer and the BC layer on which SCs are deployed. The EVM is responsible for executing SCs by reading and sending the instructions to the CPU. The EVM also maintains security of the network by ensuring that no malicious code is executed by the CPU.
2- The EVM can read instructions in EVM Bytecode.
3- Solidity is a high level programming language that can be used by developers to write SCs. Bytecode is the actual raw binary output code of any programming language that is generated by a special application known as the compiler. Once the SC is written, the SC is compiled into Bytecode so that the EVM can read and execute the instructions.
4- Bitcoin can run SCs but it cannot run the type of complex SCs that run on top of Ethereum because Bitcoin’s programming language Script only allows for very primitive functions to be carried over the Bitcoin BC. Script is a non-TC language because Bitcoin Script cannot implement loops, and therefore is very limited in terms of program complexity. Whereas Solidity is TC and can theoretically solve any computational problem over Ethereum BC given enough physical resources.
5- A TC programming language is a language that can be programmed to calculate any computational problem that a Turing Machine can do given enough memory and resources. A TM is characterized by its ability to store the state of the program and its ability to implement loops and conditional branching in order to achieve the desired output.
- EVM(Etherium Virtual machine) creates a buffer between the execution code and the computers CPU. It take the bytecode from what ever language the code is written in and executes it instead of allowing the CPU to be taken over from the code.
2.EVM can use any bytecode format of code language and be able to execute it on the blockchain.
-
Solidity is the programming language used for Etherium. The code is compiled into bytecode which can executed by the EVM to be executed on the blockchain.

Bitcoin language(Script) is what is called a non turing complete complete language.
-
A turing complete language allows for Loops to be executed in the program.
-
the EVM is an application ran on a computer that can read and execute smart contracts. It also separates the CPU from the smart contracts to improve security.

- Solidity is the language that smart contracts are written in, but then the instructions are compiled into Bytecode so that the EVM can read it.
- The language written for Bitcoin is not Turing complete and so is too basic to be able execute complex programs.
- A Turing complete programming language is a language that is complex enough to read and execute a certain amount or complex rules that it may be given.
-
The EVM is an application that runs on top of the hardware on every node in the Ethereum network. This serves as a middle man between the CPU and the deployed smart contract. It, instead of the CPU, reads the smart contract directly and then tells the CPU what to do. This is in order to preserve security amongst the network, because a malicious smArt contract could gain control of the CPU and breach the system. The EVM encapsulates the smart contract.
-
The format the of the instructions the EVM can read is called byte code.
3.The relationship between Solidity and Bytecode is the program is written in Solidity (looks like English) and is compiled into byte code, in which the EVM reads.
-
Bitcoin can’t run the same type of complex programs like Ethereum can because the programming language it uses, Script, isn’t a Turing Complete protocol.
-
A turing complete programming language is one that can solve every problem/math equation you give it. Bitcoin’s is very simple - and for good reason. Bitcoin isn’t meant to be scaled for smart contract purposes, because the simplicity of having it as just a simple, secured digital currency is its main objective.
