No central parties control Ethereum accounts.

@neychokoev just load the ethereum wallet client @ ethereum.org
or you could build your own wallet client using the source code
or you could go to myetherwallet.com and create a wallet there

Hi, I am trying to create a project like https://www.everledger.io/ where I would upload a hash identifying a physical object on blockchain with its owners account, and anybody can verify who is the original owner of that object
Whats the best way to go about it? Should I do this on ethereum blockchain or can I do this on my own private blockchain? It is just for a test project

i'm sorry, but do you have any grasp of the size of a project like that? everledger was build by a multinational team for many many days
and you come in here asking if you somebody could help you setting it up for a test project
so, @pranay01
so @pranay01, if you just want to copy and paste another teams work, nobody will help you here
and if you want cookiecutter answers to your specific problems you don't understand the way this (or any) community works
to set up the whole everledger project for "testing" purposes is possibly the tallest order i could imagine right now
maybe you should start by learning about blockchain and decentralized apps, how they work, what you need, how you write them
and then the real questions will come to you: how do I implement a struct? how can i call my functions?
those are the kind of question you might find an answer for in here

Jul 24 2017 14:16
but coming in and essentially asking people to do your project for you is not the way you'll gain anything here
also, check your expectations, all those people walking in here, thinking they just have to copy existing programs to the blockchain and call it a day, don't have any real understanding what decentralized apps are and how we can benefit from them
nobody needs another everledger
nobody needs another database on the blockchain
nobody needs your copy and paste idea of something that's already been implemented by someone with more brain and resources then you!
i'm sorry for getting carried away but i'm fed up with people coming into these chatrooms and essentialy asking for implementations of half-baked ideas
maybe first understand the technology and then try to build your killerapp?

@ENiG87 Got your point.
Have read the basics of blockchain and ethereum. Wanted to start coding now to get hands on.
Had this basic doubt if I should do this on ethereum or my own blockchain.
ENiG87
@ENiG87
Jul 24 2017 14:23
well, then i suggest you try yourself on programming one of the examples provided on ethereum.org
Pranay Prateek
@pranay01
Jul 24 2017 14:23
May be I have not read enough.
But was not sure how to start doing this for the above example.
ENiG87
@ENiG87
Jul 24 2017 14:24
then i can suggest to you to test via remix
and deploy on testnet chain
you should only deploy on the real ethereum chain if your dApp is donedonedone!
and i mean donedonedone in the sense of "i'll never have to look over it ever again for all eternity!"

@pranay01
Jul 24 2017 14:25
Sure. I understand that copying pasting another project will not help me. But unless I try few examples I wont get to understand the nuances.
ENiG87
@ENiG87
Jul 24 2017 14:27
yeah, but it's a far step from copying an example like the token contract to wanting to implement a highly sophisticated system like everledger, developed by one of the 3 biggest techcompanies in the world (ibm) and programmed by literal hundreds of people!
you could implement a very basic form of it

I dont want to implement complete everledger -> I would upload a hash identifying a physical object on blockchain with its owners account, and anybody can verify who is the original owner of that object
ENiG87
@ENiG87
Jul 24 2017 14:28
if you already tried your heand on the voting contract you should know all the basics to implement a basic everledger
you could accomplish that by simply declaring your storage variable/struct/etc as public
Pranay Prateek
@pranay01
Jul 24 2017 14:28
My doubt was shoud I do it on testnet/ or a private blockchain
ENiG87
@ENiG87
Jul 24 2017 14:29
you can just do it in remix
Pranay Prateek
@pranay01
Jul 24 2017 14:29
Ok. Got it.
ENiG87
@ENiG87
Jul 24 2017 14:29
there you don't have to pay anything
i mean, think about it: if you do it on your private blockchain then you're also responsible for mining that chain
because without mining there will be no transactions
Pranay Prateek
@pranay01
Jul 24 2017 14:30
Yes. But won't mining be easier if its private blockchain?
ENiG87
@ENiG87
Jul 24 2017 14:30
so to run a complete chain just for the purpose of testing is only feasable for a bigger project, possibly one where you'll get payed
you have to check that yourself whats more comfortable for you.
but why would you do that if you can just test your code in remix.ethereum.org?
and remember: if you deploy on testnet chain you'll need testnet ether
Pranay Prateek
@pranay01
Jul 24 2017 14:31
Sure. didnt know about remix. will look into it.
Got it. Anyways, didnt want to hurt feelings of the esteemed members of this community.
ENiG87
@ENiG87
Jul 24 2017 14:31
which can be minded via the ethereum wallet
don't get all smartass on me now
Pranay Prateek
@pranay01
Jul 24 2017 14:31
May be I got ahead of my learning curve.
ENiG87
@ENiG87
Jul 24 2017 14:31
you definitly did
Pranay Prateek
@pranay01
Jul 24 2017 14:32
Ok. Will keep in mind

@pranay01 you can also check into the truffle project for development
ENiG87
@ENiG87
Jul 24 2017 14:32
if i have to explain to you the difference between private and testnet chain and mining, etc..
Pranay Prateek
@pranay01
Jul 24 2017 14:32
@rfikki Sure. Thanks
ENiG87
@ENiG87
Jul 24 2017 14:32
remix is the way to go for quick testing of code you just wrote

@pranay01 if you need some ropsten testnet ether, just ask here: https://gitter.im/ethereum/ropsten

@all, anyone know where a good forum is where I can learn about how to best manage the volatility of Ether in a real-world application ?
