  1. What does the EVM do?
    EVM stands Ethereum Virtual Machine and its task is to communicate with the nodes CPU and give it instructions on what to do.

  2. What is the format of the instructions that the EVM can read?
    The format of the instructions given to the EVM are in byte code.

  3. What is the relationship between the programming language Solidity and Bytecode?
    The relationship between Solidity and Bytecode is that Ethereums code is first written in Solidity, which is then put into a special application that translates solidity code into byte code, which is what the EVM will read.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin can´t run the same type of complex programs that Ethereum runs because it uses SCRIPT, a not turing complete language.

  1. What does the EVM do? EVM, ETH virtual machine, a component of consensus, is an intermediary between the blockchain and CPU’s that launch smart contracts by reading and executing byte code. It is a security feature in this role, eliminating the need for the CPU to interact with the smart contract, which would result in compromised security.

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

  3. What is the relationship between the programming language Solidity and Bytecode? The byte code is written in solidity, EVM reads instructions in byte code.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can? Script, the programming language for BTC, is not capable of executing smart contracts, the programming language is limited.

  5. What is a Turing Complete programming language? A true and complete language is one that has loops that perform various, repeatable tasks.

  1. The Ethereum Virtual Machine (EVM) is an application that runs on each node of the Ethereum network. By having an EVM, a node and its CPU are protected from potential malicious activity. Encapsulating the smart contract within the EVM makes this possible.
    The EVM reads the contract, calculates and then instructs the CPU of each node what is to be done; all along the way, delivering the contract to a new state-of-being as it advances in maturity.

  2. The instructions that the EVM can read are in the byte code format. The “lingua franca” nature of byte code allows for other programming languages to be used beyond Solidity and Viper.

  3. Solidity is the programming language used to write or program the smart contract. From there, a separate application called a compiler translates the smart contract into Bytecode which will then be read by the EVM to instruct, or be used to instruct, the CPU.

  4. Compared to Ethereum, Bitcoin is limited; some might even say that it is primitive. This is because Bitcoin is not fully programmable—it isn’t “turing complete”—and is unable to run the same type of programs of complexity that Ethereum can.

  5. Turning complete language allows a programmer to instruct the execution of an action multiple times. These are called “loops”, and they allow for the duplication of code with fewer chances of mistakes and less time taken, had every code input been scribed, manually.

  1. The EVM can read and execute smart contracts on the Ethereum Network. It also allows us to execute code on top of the Ethereum Blockchain.

  2. Bytecode

  3. The relationship is that the code is transferred from Solidity to Bytecode in the smart contract. The instructions of the smart contract are in Bytecode but the smart contract was made with Solidity.

  4. Bitcoin can’t run the same complex programs as Ethereum because Bitcoin’s language Script is not Turing Complete and this scalability would cause the block size to increase.

  5. A Turing Complete programming language is one that can do anything you program it to do. An example of a Turing Complete programming language is Solidity.

  1. What does the EVM do?
    EVM - ethereum virtual machine, it is application running in all nodes. It is running on top of each hardware of each node, EVM will use CPU and other resources and it will read and execute smart contract.

  2. What is the format of the instructions that the EVM can read?
    EVM can read instructions written in bytecode - solidity program (in the future Viper). EVM doesn’t care what application will write code, but it has to be written in bytecode.

  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is written in Bytecode and EVM will only read Bytecode.

  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Bitcoin is using script, it can do let’s say multiscript wallet, it is not turing complete programming language and it means, it can not solve all the issues. It doesn’t have loops (feature of programming language, to do 1 thing several times until complete), If you don’t have loops you have to write all the instructions by yourself and it can cause spamming or issue of blockchain size.

  5. What is a Turing Complete programming language?
    Theoretically it can solve all the problems, practically there is scalability issues.

Hi everyone,

  1. EVM (Ethereal Virtual Machine) works on top of the CPU to read the instructions of the smart contract and tell the CPU what to do. It adds an important layer of security to prevent malicious instructions (which could be included in the smart contract) from being run on computers.
  2. It reads bytecode.
  3. The programming language is Solidity, it is compiled to be “translated” in byte code, which the EVM can read.
  4. Bitcoin is using a script which is not Turing complete, i.e. it can not solve all problems, it is just doing basic/limited instructions.
  5. A turing complete programming language can perform any kind of computation, which will enable it to solve complex issues. For example, a TC can do loops (repeat the same instructions many times).

  1. What does the EVM do?
    The ethereum virtual machine is the environment which all smart contracts execute in. It has access to all of the nodes on the network and keeps them in sync. It also protects the nodes from direct access from the smart contract so the contract cant take over the nodes.
  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?
    Ethereum smart contracts are written in Solidity which is compiled into Bytecode
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Because it isn’t Turing complete. This is by design to keep the focus on bitcoin as currency and keep the block size down.
  5. What is a Turing Complete programming language?
    A language that can, in theory at least, solve all problems. Ethereum is Turing complete. Bitcoin is not.

  1. The Ethereum Virtual Machine a piece of code that runs on Ethereum nodes, and executes the compiled code from the smart contracts.
  2. the EVM reads insttructions in byte code. a compiler compiles the code from Solidity to Byte code.
  3. Solidity is the language used to write the smart contracts and an compiler then compiles that code to Byte code.
    4 because the Founders of Bitcoin did not want Bitcoin to be be spammed with data , so they made the Bitcoin protocol not Turing complete.
  4. A Turing complete language is a language that is able to perform any mathematical operation that can be coded. Solidity is an example of a turing complete language.

  1. What does the EVM do?

EVM is an appllication running on top of eacht hardware of every node in the network. It can execute code, as long as al nodes are in consensus. The EVM will read and execute the smart contract ( and check if there are malicious intstruction in the smart contract) via CPU.

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

EVM can read Bytecode. For example solidity/viper, it doesn’t matter with what application the bytecode is written.

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

Solidity is an compiled written bytecode, which the EVM will read and execute.

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

Bitcoin is using script which is not Turing Complete. The program can not solve all problems, only the basic instructions. The bitcoin script doesn’t use loops, which means you have to write all the codes by yourself.

  1. What is a Turing Complete programming language?

It’s a programming language that can do anything you can think. So it’s able to solve complex issues.

    It’s a regular virtual machine. It gives the possibility to run a smart-contracts compiled into the bytecode.
  2. What is the format of the instructions that the EVM can read?
    It’s byte code. Programmer should compile their solidity/viper instructions into the byte code.
  3. What is the relationship between the programming language Solidity and Bytecode?
    Solidity is a programming language and the compiler can compile it to the Bytecode
  4. Why can’t Bitcoin run the same type of complex programs like Ethereum can?
    Because complexity of such network with complex programs is very high and computing time of blocks adding and transactions creation will be increased. The main Bitcoin idea is the digital gold without any additional complexity.
  5. What is a Turing Complete programming language?
    The TC language provides possibility to write any idea you can think.

  1. The EVM is a software interface between the CPU and smart contract that reads and executes the contract. It interprets the instructions, compiling them from the smart contract language to byte code and instructs the CPU accordingly. The EVM also contains the smart contract acting as a critical security interface for the network.

  2. The EVM reads byte code compiling it down from the contract programming language.

  3. Solidity is byte code written in user friendly terminology.

  4. Bitcoin uses script as a programming language which is not Turing complete.

  5. Turing complete languages have a programming feature called loops that allow a programmer to tell software to do something several times.
