The document discusses Ethereum smart contracts, including an overview of Ethereum as a blockchain platform that supports smart contracts. It defines smart contracts as computer programs that implement contractual rules without intermediaries. It describes how to write smart contracts using Solidity and how the code gets executed on the Ethereum Virtual Machine (EVM). Benefits of smart contracts include autonomy, trust, and savings from eliminating intermediaries. Examples of smart contract use cases include voting, management, IoT, and medical records. The document concludes by mentioning gas fees for code execution and incentives for smart contract development.

2. Ethereum Smart contract Development
Ethereum is a public, distributed computing blockchain-based platform featuring smart contract
functionality. Developcoins is a one-stop solution to your blockchain and Ethereum smart contract
development.
We start by introducing you to the basics of Ethereum Smart Contract. You'll learn about
Ethereum smart contract development process, benefits much more. We'll cover mechanisms of
advanced smart contracts in detail. You'll also learn how to write your own Ethereum Smart
Contract from scratch in detail.

3. Ethereum Smart Contract Overview:
Ethereum is a “Blockchain Platform”. it does not only support a distributed ledger but it also
supports Smart Contracts.
Smart contracts contain code of functions and can interact with other contracts to create
decisions, save data, and send ether to others. Smart Contracts are computer programs that have
the code that implements contractual rules between two or more contract parties. The rules
coded in the smart contract are provoked by events in the world and automatically carry out some
predefined actions. All of this happens without any mediator, web servers, or back end databases.
Smart contracts are the best way to ignore any third party from the transaction and make
transaction prices lower, as they require no validation.

4. How Do You Write a Smart Contract?
Basically, a smart contract is like a class explanation in object-oriented design. It has data,
functions, or methods with conditioner public or private, along with getter and set of functions.
Specific programming languages have been designed for coding smart contracts. Solidity is one
such language.
Let's examine a simple Solidity smart contract to understand its structure.
* 1st line with pragma indicates the form of the solidity language. The contract's name is in the
first line. This specific contract is for one integer storage. The data for the integer is explained with
type a name, uint stored data.

5. How Do You Write a Smart Contract?
* Two functions are described for writing and reading the data. Set and get. Code execution. Where
does the code in the smart contract get completed? Where is it located in a node? We want a
computational infrastructure to implement any arbitrary code.
* Every node in the Ethereum blockchain network should be able to execute the code impartial of
that basic type of hardware or operating system. Enter Ethereum Virtual Machine, EVM. An EVM
provides a run anywhere obstruction layer for the smart contract code.

6. How Do You Write a Smart Contract?
* A smart contract written a high-level programming language is translated into EVM byte code,
and then, deployed on the Ethereum Virtual Machine. All nodes will host the same smart contract
codes on the EVM. Smart contracts add a layer of logic and computation to the trusted network
supported by the blockchain.
* Smart contracts allow for the implementation of code. Increasing the basic value transfer
capability of the Bitcoin blockchain. The code for this smart contract is written in a high-level
language like Solidity and compiled into byte code. The code for the smart contracts is executed on
an exclusive structure known as Ethereum Virtual Machine.

7. Benefits of Smart Contracts
Autonomy — Smart contracts eliminate the need for a third-party intermediary of the promoter,
actually giving you full control of the agreement.
Trust — No one can lose any of your documents, as they are encrypted and safely stored on a
secured, distributed ledger. Also, you don’t have to trust agents you’re dealing with or expect them
to trust you, as the honest system of smart contracts essentially replaces trust.
Savings —Real estate agents, advisors, assistance, notaries, and many other intermediaries have
not required thanks to smart contracts.
Safety — If we executed correctly, smart contracts are highly difficult to hack. Also, perfect
environments for smart contracts are secured with complex cryptography, which will keep your
data safe.

8. Smart Contract Use Cases:
Smart contracts are enforced in a lot of cryptocurrencies to control the transfers of digital
currency, build governance, and a lot of other things. But smart contracts have a wider range of
possible applications. Smart contracts may be used in voting, management, machine-to-machine
interactions in the IoT, real estate, and in the building of personal data stored with exact access
policies, e.g., medical databases.
Smart contracts can be used for a wide range of things. Developers can develop smart contracts
that provide features to other smart contracts, similar to how software center work. Or smart
contracts could simply be used as an application to store information on the Ethereum blockchain.

9. The N number of smart contracts deployed on the
Ethereum blockchain network reached 1,971,632 in
March 2020, reaching a new all-time high and
marking a 75% increase from the previous month.

10. Programming Languages For Writing Ethereum Smart
Contracts
Solidity: It is a contract-oriented high-level language with syntax related to that of JavaScript and
it is designed to target the Ethereum Virtual Machine (EVM).
Serpent: Serpent is a high-level language designed for writing Ethereum contracts. It is very
similar to Python, but Solidity is the most preferred language of smart contract development for
Ethereum developers. Viper: Viper has a Python-like indentation scheme. It targets on security
and language and compiler unity.
Lisk: Lisk uses javascript as a smart contract language that makes it easier for a developer to code
smart contract applications. Chain: Chain offers enterprise-grade blockchain infrastructure with
SDKs in familar languages such as Ruby, Java, and NodeJS.
