I have a requirement where we need to save data(pdf) to blockchain so that any third party can access and view it later by the block address. I can't store the hash of the data on blockchain as the third party does not have access to the original document to verify the hash of the data. Is it feasible?

Deep Vora

@dv29

I'd say its not feasible, as storing data on blockchain is really expensive

https://hackernoon.com/ether-purchase-power-df40a38c5a2f

also if you end up doing that, encrypt your file before storing on blockchain

We can create ERC20 tokens using solidity or even metamask.. but how to create unique address to transfer them?

I mean token like Gold reward or coins like Bitconnect has it's own pattern of address to transfer in between. how to do that?

In HitBTC also for every token you will get unique address to send..

if is there any way to do this, need to do that during the contract deployment or can be done after creating the simple token ?

Hi, i have used the functions from https://www.ethereum.org/token ,, it deploys perfectly, but returns an error "the constructor should be payable, if you send value" message while attempting to buy tokens using ether (in Java Script VM) . I have also made the constructor function payable.. still it returns error :(

@akashashen

Where would be the best place to get help on deploying a token regarding myetherwallet? I've choked out something that I suspect was malformed and can't afford to make that mistake again.

Myles MacGregor

@MPA-MRK

When I try to develop a new contract, why is the line "function MyToken(...)" wrong?

sahni619

@sahni619

How do we deal with this error : Defining constructors as functions with the same name as the contract is deprecated. Use "constructor(...) { ... }" instead.

I am new to ethereum and need some help with this

Ali

@AboShanab

Hey guys, how can I verify the contract on etherscan?

anuragLHT

@anuragLHT

@sahni619

The reason of this warning is that : in latest version of solidity , constructor function should defined with the keyword constructor not with the name of the

Contract

sahni619

@sahni619

Thanks @anuragLHT

So Now function myContract () {
}

willl b something like constructor myContract () {

}

???

Will it be used this way

anuragLHT

@anuragLHT

@mayank-sahai

@sahni619 no just write constructor (arguments) , nothing else

sahni619

@sahni619

ok. thanks @anuragLHT

Akshay Dev H

@akshaydevh

@MPA-MRK just use constructor(....) instead of function MyToken(...)

Akshay Dev H

@akshaydevh

@AboShanab click on the verify and publish link ...then copy paste your entire smart contract code,,,, Ensure that the compiler version must be same as that used for deploying the contract. also you should check the optimization option ..
