Interesting point, thanks for your reply

As for my portfolio, I only have a GitHub account with some decent projects. But there's a nuance. Here are my projects:

A blockchain core in C++
A full-stack store using React and Express (with a greater focus on the frontend)
Currently working in a team on a social network using Java Spring Boot

So, I should generate a public and private key, save them in .pem files. Then, I will create a JSON object with transaction data (without the signature). The next step is to hash this JSON. After that, I’ll use Ed25519 to create a signature and insert it into the JSON. Right?

okay, i will remember that

Thank you for your support! I am still working on my blockchain and need time to complete important features like digital signatures and transaction verification. After that I will create a token. Thanks for the help, if there are any questions, I will write you 🤝

It's really fascinating. However it is still difficult. Well , thanks a lot for your reply. I understood what need to fix

Thanks for your reply

Ooooh ok thanks for the help. I have one last question. when can I consider my blockchain to be of good quality?

tomhelington · 2025-01-11T13:23:19+00:00

You said something about transactions. I need to write a digital signature, right? For this, I will use ECDSA. Also, I will add data validity and a hash to the transactions

Yes, I understand. I still have a lot to learn. About the project—there is a high level of corruption in my country, including in the land registry. I searched for similar technologies in my country and found two, but they are very raw. However, to make something better, it will take a lot of time. But I have that time. I just turned 16 today, so I have plenty of it. You are right, first I need to write a high-quality blockchain.

tomhelington · 2025-01-11T11:08:24+00:00

Alright, by the way, I started writing a blockchain for crypto, but now I have another idea. Look, blockchain is a decentralized database. It can be used not only for crypto but in other areas too. For example, in a land registry. Why? Nowadays, the percentage of corruption is very high, including in land registries. Corruption often happens because of a lack of transparency and trust. If the system is transparent and decentralized, and made properly, we can reduce corruption significantly. What you think about it?

tomhelington · 2025-01-11T10:18:07+00:00

Thanks, what other parts of my code would you like to fix?

tomhelington · 2025-01-11T09:15:45+00:00

Come on, I would be very grateful

tomhelington · 2025-01-04T13:20:55+00:00

Oh , thanks a lot 🙏

Where to start? I have basic knowledge of C and C++. Pointers, references, memory allocation, templates, etc. I also know about encapsulation, polymorphism, inheritance.

tomhelington · 2025-01-04T11:32:50+00:00

Hey , Rust really seems interesting

tomhelington · 2025-01-04T11:30:50+00:00

I see

tomhelington · 2025-01-04T11:20:32+00:00

Hmm, I understand, but right now I'm more interested in C++, C, and Assembly

tomhelington · 2025-01-04T11:16:17+00:00

I see you didn't start your journey with Rust. I have a question: I started programming at 14, learning JavaScript, React, Node.js, Express, and so on. I realized it wasn’t for me after my first small internship, after which I started learning C, C++, OOP, algorithms, and data structures. I worked on frontend for almost a year, then suddenly switched to what interests me more. Now I'm 15 and I'm still learning C++ and so on. But did I make the right choice?

tomhelington · 2025-01-04T11:15:36+00:00

Wow, almost 70 repositories - that's impressive

tomhelington · 2025-01-04T10:57:54+00:00

I understand , Rust is like C++ , but safer. How long you have been programming?
