  11. Smart Contracts Smart Contract is a computerized protocol wherein you write a standard contract rule that is immutable. Smart contract v1.0 { if (England wins the match): send(10 eth, Bob) else: send(10eth, Andy) def send(amt, to): this.balance -= amt send.balance += amt } Copyright © 2017, edureka and/or its affiliates.

  12. What was the need to develop a contract-specific language? Why couldn’t we use the already existing languages? Copyright © 2017, edureka and/or its affiliates. All rights reserved.

  13. Solidity for Smart Contracts Solidity is a contract-oriented, high-level language for implementing smart contracts on the Ethereum Virtual Machine (EVM). SOLIDITY Copyright © 2017, edureka and/or its affiliates. All rights reserved.

  16. Ethereum Virtual Machine (EVM) Contracts written in a smart contract-specific programming language are compiled into ‘bytecode’, which an EVM can read and execute. Copyright © 2017, edureka and/or its affiliates. All rights reserved.

  17. What’s preventing a piece of code from running forever and overloading the network? So if the EVM is running application code…. Copyright © 2017, edureka and/or its affiliates. All rights reserved.

  18. Ethereum Gas GAS LIMIT GAS Gas is the unit for the amount of Gas Limit is the maximum amount of computational work done by the gas the contract can use for its computer for one cycle of the contract computations Copyright © 2017, edureka and/or its affiliates. All rights reserved.
