- What is the relationship between the programming language Solidity and Bytecode? Ethereum is programmed in Solidity; but a compiler is used to “translate” into bytecode so that the EVM can execute the Smart contracts
- Why can’t Bitcoin run the same type of complex programs like Ethereum can? Because BTC is programmed in Script which is not turing complete
- What is a Turing Complete programming language? It’s the way solitity is; and it means it can do anything it’s programmed to do and also has loops which can execute something n times.

1- EVM executes the code in each of the node 9computers of the network.
2- EVM doesn’t allow the smart contract to run directly each node
3- Solidity is the proggram that writes in a language called byte code. Solidity produces the byte code.
4- Because the script language of bitcoin is very limited.
5- In theory, developers can make any application they want in a Turing complete programming language.

- EMV stands for Ethereum Virtual Machine. It interprets and runs smart contracts.
- EMV reads Bytecode from the Solidity compiler.
- Solidity is used to write the smart contracts. The compiler takes the code and compiles the logic into Bytecode. The EMV then reads the Bytecode.
- Bitcoin is not Turing compete. It cannot solve all problems due to no loops being integrated out of fear of spamming. Its block size is also limited.
- A Turing complete language contains Loops.

1: EVM is an application on all nodes that executes the smart contracts on the ethereum blockchain. It instructs the CPU to run the Smart contract application and allows the nodes to come to consensus.
2: EVM reads the smart contracts written in byte code
3: Solidity is the programming language of ethereum that is then translated to Bytecode using a compiler and EVM then read the Smart contracts written in bytecode.
4: Because its programming language, Script, is not turing complete.
5: A turing complete programming language can, in theory, accomplish any task. The main factor presented in this course is the ability to run loops that can adapt to variables that may change from one execution to the next.

The EVM or Ethereum Virtual Machine is a program that reads the smart contract commands, complies it, and then translates it into bytecode for CPU compiling and execution.

Evm is running on top of every hardware so they will use all the resources like CPU, it can also read and execute smart contracts.
So the Evm will look at all the instructions from the smart contracts and then do the calculation ect and then give the instructions to the cpu on every node what to do and then it will reach the results . thats how they reach consensus. -
Bytecode
-
After you have programmed the instructions on solidity you compile the codes to bytecode so the EVM can run it.
-
Bc its not turing complete, its very primitive so there is limits on what you can do on script.

- EVM (Ethereum Virtual Machine) Allows for us to execute code on a global decentralized network to ensure all CPUs running the EVM script (solidity) are in consensus to verify what a result should be. Implementing this Turing complete script allows the CPUs to indirectly execute smart contracts once the EVM executes it directly after compiling the instructions into byte code then processed by the CPUs. The EVM also provides security by not allowing a potential malicious script to take direct control of the network (CPU; hardware) by providing an encapsulated OS environment to run requested smart contracts and transactions. Lastly, due to it’s Turing complete feature, anything becomes programmable, scalability becoming the only potential hurdle.
- It reads byte code created by a compiler responsible for reading the code/instructions.
- Solidity is the programmable language interpreted into byte code by a compiler that the EVM then reads/executes.
- Bitcoin’s Script language is much more simple/not Turing complete.
- A Turing complete language allow programmers the flexibility to program whatever they want by allowing the implementation of other programs like the loop feature for redundancies and manipulate them accordingly. It can solve any computational problem.

EVM is the Ethereum Virtual Machine and runs smart contracts on the nodes in the network. It is unstoppable and transparent, while delivering specific instructions for each transaction.
The EVM reads byte code.
Solidity is compiled into byte code using a compiler, and the byte code then runs (through the EVM) on the CPU of a node, just like every other programming language.
Bitcoin’s network is not turing complete. Ethereum is turing complete.
Turing complete programming language capable of being customized, in order to accomodate smart contract capabilities across transactions.

EVM (Etherium Virtual Machine) is another level of the ETH network that makes it possible to run “Smart Contracts” on the ETH Blockchain. EVM runs on all nodes in the Blockchain and acts as an intermediary between the Smart Contracts and the CPU,s on the nodes. The EVM will read all instructions in the smart contract and tell the CPU what to do.
