- The EVM is a global machine that runs on top of the etherum blockchain. All the nodes on the blockchain runs the EVM and it can be used to run layer 2 functions like smart contracts.
- the EVM only reads bytecode.
- the EVM reads and executes bytecode, but doesn’t care which programme language the smart contracts are written in. It can be written in Solidity or Viper but will then be convered to bytecode for the EVM.
- Because the programming languge for BTC (script) is not Turing complete
- It means the language can code for everything you want.

Solidity is the code that is used to write smart contracts on ethereum. Solidity code is then assembled into bytecode by a complier in order for the EVM to read the smart contract. EVM does not care which programming is used so long as it is converted to bytecode.

Bitcoin’s programming language, Script, is not a Turing complete language, so it cannot run complex types of programs.

A Turing Complete programming language is a language that can run loops, which are pieces of code that allow the programmer to carry out an action several times without having to write out each line of code repeatedly.

- In short EVM executes a code on the network in a way that makes all Nodes come to a consensus about what the result should be. It runs on top of each node using all the resources it needs, it isolates, reads and execute smart contracts. All nodes will execute all the instructions of a particular smart contract and need to produce the same result.
2.Byte Code
3…EVM executes instructions with Bytecode but the codes will be written with solidity that compile to Bytecode.
4.Because Bitcoin doesn’t use solidity but uses Script which is Turing incomplete meaning its limited in what it can program.
5.Means You can solve all problems for programming applications and create whatever you can think off.

What does the EVM do?
The EVM functions like a shared CPU for the entirity of the Ethereum network. Each node runs a copy of the EVM, and each node can carry out the instructions laid out in a smart contract on the block chain. When all versions of the EVM reach the same conclusion, there is consensus on the blockchain. -

1. What does the EVM do?
The EVM (ethereum virtual machine) is a protocol to the ethereum blockchain that runs isolated to the computers in the networks. It is able to read a smart contract and execute the instructions. It ensures that no malicious smart contract is executed on the actual ethereum blockchain without first being executed and tested on the EVM. This makes it a very good security option for the network as smart contracts can be executed safely.
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 is ethereum programming language. When a smart contract is initiated it translates the solidity language through a complier into bytecode which the EVM can read and execute upon.
4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
BTC cannot run the same type of complex programs because it programming language is script. This language is not turing complete meaning it cannot complete all computation problems it is presented.
5. What is a Turing Complete programming language?
A turing complete programming language is a that can be programmed to do basically anything as long as there is is computational power behind it e.i. power, time, etc.
Solidity is such a language.

The EVM (Ethereum Virtual Machine) reads the Byte code in smarts contracts and then if consensus is reached between the different nodes running on the Ethereum Network then the code is then passes on the information to your CPU to execute.
-
The format of the instructions is first written in Solidity and then ran through a compiler which turns the script into Byte Code which is then in turn read by the EVM (Ethereum Virtual Machine).
-
The relationship between EVM (Ethereum Virtual Machine) and Solidity is that the code is originally formatted in Solidity as it is easy for use to read as it is much like English. However the the EVM reads and executes code in a different language so a compiler is used on the Solidity code and the new format of the code is changed to Byte Code.
-
Bitcoin cant run the same type of complex programmes like Ethereum because the Bitcoin doesn’t have a Turing Complete language meaning it can not work out any problem. Ethereum does have a Turing Complete language (Solidity).

A Turing Complete language is a language that enables you to theoretically solve any problem. whilst this is possible in theory it is not so in practice as time and money are often factors that can stop developing a project. A Turing Complete language has the ability to run loops in a program meaning the same task can be completed several times over.

The Ethereum Virtual Maschine processes simply said converts the bytecode of a smart contract, written in Solidity.
It is important to say, that EVM is running in a kind of sanbox to keep other hosts safe.
2. What is the format of the instructions that the EVM can read?
An EVM can read code written in Solidity and also in VIPER which is a “new prog. language”
3. What is the relationship between the programming language Solidity and Bytecode?
Solidity can be written buy humans, hopefully by me in a couple of weeks. And the EVM translate my lines written in solity into bytecode.
A simple relation between human, compiler and bytecode leads to actions.
4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
Because Bitcoin has ut`s own simpler language (SCRIPT). The suggestion from Vitalik was not really welcome in the world ob BC developers.
And this was the beginning of Ethereum
5. What is a Turing Complete programming language?
This languages can execute ANY mathematical operations. As example loops which do not exist in a simpler language
