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

Quite close sir, but Solidity is the programming language that you use to create/design smart contracts, after that, it will be compiled into ByteCode, so the format of the instructions that EVM reads is Bytecode.

If you have any more questions, please let us know so we can help you! :slight_smile:

Homework on EVM - Questions (Updated on Dec 3 2019)

  1. What does the EVM do?
    It improve the portability of software, as well as to make sure applications are separated from
    each other, and separated from their host.
  2. What is the format of the instructions that the EVM can read?
    EVM uses a set of instructions called OPCODES to execute specific tasks.
  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is a statically-typed programming language designed for developing smart contracts that
    run on the EVM. Solidity is compiled to bytecode that is executable on the Ethereum Virtual
    Machine.
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin Script is a simple, stack-based programming language that enables the processing of
    transactions on the Bitcoin blockchain.

With its own complex programming language, Ethereum makes it possible for blockchain
technology to be many applications , that means applications that aren’t money-related. And it
allows for more complex smart contracts to be implemented.
5. What is a Turing Complete programming language?
Turing Complete refers to a machine that, given enough time and memory along with the
necessary instructions, can solve any computational problem, no matter how complex. The term
is normally used to describe modern programming languages as most of them are Turing
Complete (C++, Python, JavaScript, etc.).

  1. What does the EVM do? The EVM is an application that reads and executes smart contracts. The EVM is a piece of code that all the network nodes are running and maintain a copy of in order to achieve consensus.
  2. What is the format of the instructions that the EVM can read? The format that is read in is Bytecode
  3. What is the relationship between the programming language Solidity and Bytecode? Solidity would be used to construct the smart contract with instructions which will be in bytecode. The Solidity code uses a compiler that compiles the logic and instructions given down to bytecode. The EVM from there would read the instructions to run successfully.
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can? Bitcoin uses the Script programming language which is very limited and is not Turing complete.
  5. What is a Turing Complete programming language?A Turing Complete language allow programmers to program anything with no restrictions. Turing Complete have loops, and these loops are a feature that allows a programmer to tell the software to do something several times.

  1. What does the EVM do?,
    EVM, Ethereum Virtual Machines are present on every node. They are the ones that analyse the smart contracts and will decide to accept them or not.

  2. What is the format of the instructions that the EVM can read?
    This is what I was going to answer “EVM can read solidity” but not being sure I cheated and I guess EVM read byte code compiled from a language such as solidity (thank you jelucamur

  3. What is the relationship between the programming language Solidity and Bytecode?
    Had to review again before answering. So the contract in written in a language like solidity but to be understood by the EVM, it will be compiled into byte code.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin is written in Script which is not a Turing Complete program so is limited. However Ethereum is written in Solidity which is a Turing Complete Program.

  5. What is a Turing Complete programming language?
    A non Turing Complete program cannot solved problems that normal programming can solve. So a Turing Complete Program, can solve all kinds of math problems so you can program what you want.

  1. What does the EVM do?
    It takes the bytecode of smart contracts and runs it in each node of the ethereum network.

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

Bytecode

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

Solidity is a language that compiles smart contract code into bytecode for the EVM to run it

  1. Why can’t Bitcoin run the same type of complex programs like Ethereum can?

Because script is not a turning complete language, loops are not allowed

  1. What is a Turing Complete programming language?

  1. its a virtual machine installed at all the nodes. It can read the smart contracts byte code and execute it.

  2. It can read byte code

  3. Solidity code can be compiled into byte code which can be executed by the EVM

  4. Because the bitcoin protocol is setup differently. If smart contracts like the ones in ethereum would be executed and put on the bitcoin blockchain there would be big scalability problems as the bitcoin network block growth is very small. This is way too much data for btc protocol

  5. A programming language in which you can do practically anything you want.

  1. The Ethereum Virtual Machine (EVM) is a software/environment that acts as a middle layer between the smart contracts and the CPU. Running the smart contracts directly by the CPU increases the risk of malware spreading through the Ethereum network. The Solidity code in the smart contracts is compiled into byte code, and then fed into the EVM, who in turn sends the instructions to the CPU to be executed.
  2. The EVM can only read byte code. Therefore, the code in programming languages (like Solidity) first need to be compiled to be understood by the EVM.
  3. The relationship between the programming language Solidity and Bytecode is that Solidity is a high level programming language that gets compiled into bytecode that can be run by a processor.
  4. Bitcoin cannot run the same type of complex programs like Ethereum can because its programming language, Script, is not a Turing-complete language. This means for example that Script cannot utilize loops, like Ethereum’s programming language, Solidity can.
  5. A Turing complete programming language is a programming language with functionalities which allow you to program literally everything (no restrictions).

  1. What does the EVM do?
    The Ethereum Virtual Machine acts as an isolated, singular computing environment across the Ethereum network. This virtual computer processes transactions and smart contracts for the users on the network.

  2. What is the format of the instructions that the EVM can read?
    What happens in the virtual machine, stays in the virtual machine. Nodes supply the computing power for the Ethereum network, the virtual machine ensures that network functions stay isolated in that environment and don’t spill over to other computing components of the nodes’ hardware.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is a programming language, bytecode is the format in which the virtual machine receives applications. A compiler will take the Solidity coding and turn it into bytecode for the EVM to run.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin code does not contain all of the logical operators to be a Turing Complete language. Therefore, Bitcoin is not capable of performing certain functions.

  5. What is a Turing Complete programming language?
    In my own terms, a Turing Complete programming language can express any mathematical function.

The Ethereum Virtual Machine acts as an intermediary between a nodes CPU and a smart contract. It can execute whatever is programmed into the contract using the network as a means of consensus and providing a virtual environment for decentralized execution.

The format of the instructions the EVM can read are EVM Bytecode.

The relationship between Solidity and Bytecode is that of an interpreter. Solidity is a readable language that will compile the code into Bytecode to execute in the EVM.

Bitcoin is not able to run complex programs like Ethereum as it is not Turing complete.

A Turing complete programming language would be solidity, python, javascript, etc. A language in which you can loop or program anything you can think of.
