Build your own blockchain

[shahzadafzal]

Granted, i did search on google and found a fantastic tutorial on Hackernoon by Daniel van Flymen, so full credit to him and the awesome Hackernoon website.

I will recommend another also "The authoritative guide to blockchain development" by Haseeb Qureshi. This is also very detailed and informative. This is must read for any blockchain enthusiast.

345. Probably we better go with a fork?

It will take your comment as a sarcasm

Building a blockchain does not really mean creating a new digital currency. It distributed ledger or no centralized storage practically there could be thousands of scenarios where Blockchain could be successful. Big firms like PwC, Deloitte, and KPMG are all testing private blockchains.

So learning or developing a blockchain is not like creating a altcoin,  may be it help you find a new career. Possibilities in blockchian are endless.

How much long does it take to make own blockchain?
 and beginner is also easy to do it?

I know for fact that Deloitte have 2 specialists in Australia for DLT / Blockchain and a dedicated team.

Please take look at my google drive link and the document within with pictures and step by step.

I am not sure i can make it simpler.

I actually created my own very basic blockchain tonight.. took me like 20 hours straight to get the foundation ready. I wrote it from scratch in Java, a PoW kind of blockchain.

I gotta say, your brain really gonna hurt when it comes to the networking (peer-to-peer) part.. that was a pain in the ass! That took like 70% of all my time to figure out. Now my blockchain can send coins, mine blocks, reset/resync the whole blockchain from another node-peer if it's invalid/broken etc.

But there's still ALOT left todo, believe me. I haven't figured out how to fix the Difficulty alghoritm yet.. I just made it fixed at Difficulty 4 at the moment.

I just did it for education purposes, I have another project in mind that actually don't involve cryptocurrency.. but it needs a blockchain to run on. So I started off small to get a grasp on how a blockchain actually work from the ground up. Im just amazed how the ethereum crew manage to do what they do..

I could knock up a block-chain from scratch in under three hours and if you look on Youtube then someone gives an example of the
stub code that is only about 50 lines long.

Now to turn that into my "Own" coin, deploy and test on a network it would take me about .........................
......................... five years at a guess after nicking part of the encryption code and a few other bits.

Running a macro inside Microsoft's Excel does not mean you programmed the darn thing, your just a user, not
even a script kiddie writing VBA but if your just after a alt-coin then best check out ETH and pay them gas to host it for you.

How far did you go past adding hash codes to a linked list ?

Did you turn the transactions into skinned out objects with methods or did you simply store LIST<T> or string arrays to represent the transactions
and did you get the list to persist itself to file storage ?

Running SHA256 to represent PoW and double hashing the hash-codes as taken from Bit-Torrent should not had taken too long so did you
have time to even start the network layer because if you did then you are faster than me.

Would you admit that it would take you years to turn this into a actual working product ready for testing ?

And for those that prefer Golang, here is a more complete guide that'll help you build your own blockchain from scratch. IMO It is really a must read as it covers deeper things then other guides.

Nice tutorial and Go is much easier language than C++ too.

I perused all those videos too and what really disappoints me is that alot of those guides work on assumed knowledge.

They really arent novice friendly.

But it's like wanting to build a battle ship before you have even built a boat and takes a highly skilled team years to complete
and refine something that they can take it to market and today most of them fail so take it as mission impossible and people
should not be leading you on.

Creating your own blockchain is too difficult? For beginners it's easier to do that?

Thank You!

I have recently been going through a series of tutorials on naive chain and naivecoin. So far has been a very enjoyable read.

This is also a good idea. Build your own blockchain system. We need to save a lot of information and important data. How to build this system? You are not good at it if you buy the money is too large not necessary to spend money to install the blockchain system.

There is one available blockchain suite that can do all for you... privacy, explorer, coin mixer and atomic swap . Komodo is offering a white label blockchain development service.

It will take you a day or two of learning basics and another day or two to prepare node, compile wallet et.c. Depending on your prior knowledge it can take a week or two to pick up requirements. OP and first comment gives great links to start with.

The only question is why would you want it?

Is it really possible without a team? As far as I know it can be more than 12 month of development with a budget of at least 1 million, and its payback period will be at about half a year - yeat. Not less

Yes agree a team for a year to get something that will work in real life on the tinternet but i think some of the posters here are talking more about
knocking up a object that represents a block-chain and testing it via a function call.

Took me a month to come up with a data structure that is used for node discovery that would scale to maybe 1/4bn nodes and not much
more and I am still far from happy with the results but i could have dealt with 50,000 nodes using a XML-Data table is an afternoon

It took me a week or two to make a production ready blockchain the first time I tried. However this was not from scratch, I used open source code like most do.
