smart contract :

What Is a Smart Contract?

A smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code. The code and the agreements contained therein exist across a distributed, decentralized blockchain network. The code controls the execution, and transactions are trackable and irreversible.

Smart contracts permit trusted transactions and agreements to be carried out among disparate, anonymous parties without the need for a central authority, legal system, or external enforcement mechanism.

While blockchain technology has come to be thought of primarily as the foundation for bitcoin​, it has evolved far beyond underpinning the virtual currency.

WHAT YOU NEED TO KNOW

• Smart contracts are self-executing lines of code with the terms of an agreement between buyer and seller automatically verified and executed via a computer network.
• Nick Szabo, an American computer scientist who invented a virtual currency called "Bit Gold" in 1998,1 defined smart contracts as computerized transaction protocols that execute terms of a contract.
• Smart contracts deployed to blockchains render transactions traceable, transparent, and irreversible.

How Smart Contracts Work

Smart contracts were first proposed in 1994 by Nick Szabo, an American computer scientist who invented a virtual currency called "Bit Gold" in 1998, fully 10 years before the invention of bitcoin. In fact, Szabo is often rumored to be the real Satoshi Nakamoto, the anonymous inventor of bitcoin, which he has denied.

Szabo defined smart contracts as computerized transaction protocols that execute terms of a contract. He wanted to extend the functionality of electronic transaction methods, such as POS (point of sale), to the digital realm. 

In his paper, Szabo also proposed the execution of a contract for synthetic assets, such as derivatives and bonds. Szabo wrote: "These new securities are formed by combining securities (such as bonds) and derivatives (options and futures) in a wide variety of ways. Very complex term structures for payments can now be built into standardized contracts and traded with low transaction costs, due to computerized analysis of these complex term structures.

my definition from smart contract :

as you study in the top of the dashboard there is more definition for the smart contract for example one person say that the smart contract is the contract that is fast or do the more contract at he same of the time, in this dashboard my opinion is the low fee so lets analysis my dashboard.

as you se in the top charts I analysis the smart contract of my opinion and i do it for the more step time .

I divide the code for the 4 part but the first chart is for not order and the last four chart is for the order by desc

the second chart is for the last month .

the third chart is the last 3 month .

the forth chart is for the first of the year .

and the last one is for the las 1 year .

as you see in all of the chart there is more gas for the one of the signer and this number is not also show the more gas of the more one but also if you pay attention can easily see that most of the gas volume is very high and it is show that there are very away from the smart contract and also it is my opinion may be the are smart for the other ones opinion .

but I think the smart one is should have the low gas fee.

reference

my opinion.

as you see in the top 4 chart again I analysis the top 5 new smart contract .and again I divided for the 4 part :grinning:

the first chart is for the last month .

the second chart is the last 3 month .

the third chart is for the first of the year .

and the last one is for the las 1 year .

this are for the my opinion and also I want to say this text that if one contract have more gas fee it is away from the smart one and they should try to make the gas fee very low to be smart one and at that time may be most of the people use this contract .

and also my opinion for the smart one with low gas is the stable price for the contract because if the want to be usethis coin in the bazar the should be stable at least for the each month .

I think the should pay attention for this idea I think its so important.
