Of course! Sorry, I will search similar topics before publication.
Exactly same question has been asked two years back. Here a answer from a moderator.
Also below article could help you understand the process,

Hope you will get solution from above.
The public key is calculated by taking the generator point G and performing elliptic curve point multiplication on it with the private key. Given private key d and generator G, you do d * G. The process for elliptic curve point multiplication is detailed on wikipedia. The curve parameters are the ones for the secp256k1 curve which are defined here (section 2.4.1): http://www.secg.org/sec2-v2.pdf

Hello, bitcointalkers! I have a problem with signing transaction in my wallet implementation. I can not understand how I can generate public key that based on my private key. I have private key that I generated randomly with 256 bits. I read in A.Antonopulos book that we can receive point on elliptic curve from private key. I received X and Y coordinates, What I need to do with it for transforming in single string row (traditional public key)?
I started my impementation of blockchain and I have question about UTXO storing. Do I need to store outputs after it was used? Or maybe I need to change them status on "used", or transfer into another collection (NoSQL )or table (relation) of database?
I have Linux Ubuntu OS on my computer. It has many advantages. It is hard to catch virus on Ubuntu, Linux is open source project. It mean that developers believe in security of their OS ,because they show to people source code of Linux.
Linux is more fast . First of them, I install it on my computer. because it had a low speed of work on Windows 7. Ubuntu solved this problem.
Linux has a small size of programs relative to Windows. It is free, you can change all in this OS. It is full controlled by user.
Also Linux has built-in free tools (for example archiver, ssh for connection with server from terminal, USB flash drive launch utility, etc,
It have not unnecessary files and programs like Windows. Also it has a small size.
It is post on my site, where I describe my first impression about Linux after launching.

Wow, it is really mean that all parameters like adresses, balances, tokens I can calculate from this distributed ledger. Thank you. I started to deep learn creating of keys and it fallen in my mind that address exist only when it appeared in the transaction list (block of blockchain). I read in previous answers about storing transaction in special database LevelDB. Can I change it on MongoDB in my implementation? MongoDB use key-value structure too.
Thank you for the reference. I understand from this article that it doesn't matter how transaction info stored in the node. The main idea in distributed storage system on different nodes. Type of database on one node touch internal realization and can be various from project to project.
Because it question create a big problem in storing process blockchain data like adresses, transaction lists. Thanks evebody for answer. You helped me in my problem

Hello! I am new person in blockchain technology and I want to fasten my knowledges by writing own primitive version of blockchain. I can not understand where will be my blockchain store wallets public addresses for transactions between users. Should I use helpful database like a MongoDB or MySQL for these purposes?
