  1. What does the EVM do?
    a program that reads and executes smart contracts. All nodes of Eth network use an EVM.
    It will practically execute the smart contract of that node by telling the CPU what to do.

  2. What is the format of the instructions that the EVM can read?
    it will read the byte code that the compiler created from Solidity.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is the programming language which is turned into byte code by the Complier. The
    byte code is what the EVM will read.

  4. Why canā€™t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin uses a language that is Non Turing and too primitive.

  5. What is a Turing Complete programming language?
    a language that can perform loops.

  1. What does the EVM do?

EVM is the software above the hardware of each nodeā€™s computer it reads and runs the smart contracts and is ensuring security by indirectly using the CPU to execute instructions and not directly.

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

EVM reads its instructions as bytecode.

  1. What is the relationship between the programming language Solidity and byte code?

Solidity programming language (used for smart contracts) is compiled and translated into bytecode so the EVM can read and execute it

  1. Why canā€™t Bitcoin run the same type of complex programs like Ethereum can?

Bitcoin uses Script , which is not a turing complete language.

  1. What is a Turing Complete programming language?

A language that can execute everything that can be computable. A language that possesses the three basic control structures: Loops, Decision and sequential.

  • What does the EVM do?
    -EVM or ā€˜Ethereum Virtual Machineā€™ is a universally synchronized virtual machine. If you compare it to BTC, replace the miners/nodes w/miners/nodes + virtual machine (a programming/code system). It runs the programmed code or smart contract in the money.

  • What is the format of the instructions that the EVM can read?
    -Typically, when running application on your computer, the computer is the one reading/interacting from the program. When running a distributed virtual machine like an EVM, all connected computers running the agreed consensus code of the dapps being run in the EVM. The EVM runs the same distributed smart contracts similar to distributing a ledger in BTC of all applications unbiasedly. Your computer just runs the EVM or distributed [smart-contract] applications or DAPPS.

  • What is the relationship between the programming language Solidity and Bytecode?
    -Solidity is like a specialized JavaScript for the Ethereum network. It allows individuals to easily write code for those familiar with javascript already. Solidity specifically plays the role of translating the code into byte code. This allows for the potential usage of other programming languages that similarly translate to the universal programming language of the EVM, byte code.

  • Why canā€™t Bitcoin run the same type of complex programs like Ethereum can?

    • Simple terms, Bitcoin is unable to write complex programs because the original code or program was just not intended or able to do. Bitcoin was a programmed code/program ahead of its time. Script, the programming language of BTC is limited and unable to scale to complex programs (such as multi-sign). This was how ETH was conceptualized by Vitalik.

  • What is a Turing Complete programming language?
    -Turing complete is a programming language is able to solve or develop anything that can thought or conceptualized. Solidity is a programming language limited only by the imagination while Script non-turing complete, meaning it is a program unable to effectively adapt or adjust (it canā€™t solve or do much of anything). Loops are a significant example of a turing complete programming language.

If you program the money to say for example:

Donā€™t pay John until he receives a 70% on the test. The program will continuously check his grade on a test automatically until his grade is a 70% or above. Then when he does, the program will automatically/unbiasedly send the funds.

  1. What does the EVM do?
    EVM reads, verify and execute all the instructions in the smart contract and ā€œtellā€ to every CPU from each Node what to do .Every Node has a copy of all actions. This is how Eth network reach Consensus
    2.What is the format of the instructions that the EVM can read?
    EVM bytecode
    3 What is the relationship between the programming language Solidity and Bytecode?

  2. Why canā€™t Bitcoin run the same type of complex programs like Ethereum can?
    Because Bitcoin use Script language which is not turing complete.

  1. EVM is a piece of code that all the CPUā€™s are running. It acts as a instructor to the CPUā€™s to execute other pieces of code such as smart contracts. This feature prevents spam attacks that target the CPU which can have a devastating effect on the network.

  2. The EVM reads byte-code such as Solidity which is a language created by Ethereum.

  3. Code within Solidity gets converted into byte-code which then can be read by the EVM. Solidity allows for ease of programming by being a more condense language.

  4. Bitcoin does not use a Turing complete language and therefore cannot run the languages used on the ETH network.

  5. A Turing Complete language is more malleable and flexible allowing for more a diverse and complex range of code to be written into it such as Loop actions or smart contracts.

  1. What does the EVM do? EVMs execute the smart contract and act as the gatekeeper from the smart contract to the cpu.

  2. What is the format of the instructions that the EVM can read? EVMs read the bytecode which is complied from the programing language solidity.

  3. What is the relationship between the programming language Solidity and Bytecode? Solidity complies information into byte code, and the EVM relays that code to the cpu for execution.

  4. Why canā€™t Bitcoin run the same type of complex programs like Ethereum can? BTCs programing language script is not turing complete meaning it cannot issue loops from the programing language.

  5. What is a Turing Complete programming language? A turing complete program language has the ability to deploy recursive loops.

  1. The EVM is a virtual machine layer that instructs the nodeā€™s CPU on how to interpret the byte code.

  2. The EVM can only read the byte codes that is compiled from either Solidity, Viper or other future Ethereum programming languages.

  3. When the programming codes is written in Solidity it is in a high-level form which the CPU/EVM cannot interpret. A compiler is then used to transform this high-level code into machine-level code which is called byte code which the CPU/EVM is able to understand and execute.

  4. Bitcoin uses the Script programming language which is not turing-complete, which is a simple programming language, which is not capable of performing complex tasks such as loops. Ethereum on the other hand uses the Solidity or Viper programming languages which are turing-complete, which, by definition is capable of performing any computational tasks such as loops, etc.

  5. As stated in answer #4 above a turing complete programming language is able to perform any computational tasks.

  1. EVM piece of code that all of the computers connected to blockchain network are running, it can also read and execute smart contracts.
  2. EVM byte code
  3. When we compile the solidity code using the solc compiler, it will translate our code into bytecode , something only the EVM can understand.
  4. Because the language on which bitcoin was written is not Turing Complete (it cannot solve problems that it might have to solve)
  5. A Turing Complete system means a system in which a program can be written that will find an answer (although with no guarantees regarding runtime or memory).
    So, if somebody says ā€œmy new thing is Turing Completeā€ that means in principle (although often not in practice) it could be used to solve any computation problem.

the evm uses the cpu resources to execute what is listed inside a smart contract on the etherium blockchain.
evm reads bytecode.
solidity has a compiler that reads the bytecode.
bitcoin was not designed to have smart contracts on purpose. it can only run simple contracts. does not use turing complete
turing complete uses loops to be able to adjust to new instructions as it restarts.
