do I have to create a token to use a smart contract using Ethereum?

Ask Question Asked 7 years ago Modified 6 years, 7 months ago Viewed 577 times 0

If I want to use a smart contract, do I have to create a new currency/token, or can I do them using ethers?

If I can use ethers, what will be the consequences on the data stored and encapturing the execution of those smart contracts?

Thanks

No need to create a token. That's just one potential use of a smart contract.

All Ethereum transactions are paid for with ether.

I can't understand what "what will be the consequences on the data stored and encapturing the execution of those smart contracts?" means. If you have more (specific) questions, please ask them.

Or in other words, will creating my own token give me any advantages in managing my chain. – GeneralKenobi Commented Jan 3, 2018 at 16:13 I don t see how you even would use a token for this, let alone how that would differ from not using a token. What would the token be for? When would tokens be transferred? – user19510 Commented Jan 3, 2018 at 16:14 Add a comment | 1

As @smarx said, there's no need to create a token. I think people and companies create tokens because people seem to like earning/buying virtual points.

You can think of a smart contract like a computer software , which is executed not on a single computer or server, but by every ethereum node in the network. These smart contracts are written in such a way that for a certain state of the blockchain, the code has the same output.

So your smart contract can contain almost any business logic you need . The smart contracts for the tokens have a rather simple business logic coded into them: issue a certain number of tokens, keep track of what address what balance it holds, offer the possibility to transfer this balance between 2 addresses and that's kind of it.
