As most of you probably have some crypto assets on your own, you might have heard of the words ‘public key’ and ‘private key’. In a blockchain network, the public key kind of works as your address. If anyone else in the network wants to send you some funds, he or she is going to send it to your public key. Your private key can be seen as your signature — whenever you like to make a transaction of funds, you prove that you are the one owning the private key belonging to your public key without showing it to anyone in the network. Participants of the network, who check your transaction, can prove that you, with your public key, are the owner of the private key, without even knowing what it is. Pretty cool! But how does this really work on a more fundamental level? Let’s dig a little bit into the theory.

Imagine the following scenario: you just found a critical vulnerability that allows funds in a smart contract to be drained. The exploit, however, is complicated and requires multiple payload parameters to be set correctly for it to be effective or even profitable at all.

It quickly turns out that calculating optimal parameters by hand is infeasible, due to the complex nature of the exploit. And yet, you want to responsibly disclose a Proof of Concept (PoC) that maximizes the amount of funds that can be drained from the contract. Why? Because it’s often true that the greater the funds at risk, the higher the bug bounty reward.

In such a situation, linear programming can be an exceptionally helpful tool. This is an advanced tutorial for whitehats who are looking to take their hacking skills to the next level.

In this series of posts, we will show how to execute a PLONK zero-knowledge proof system completely by hand. All of the math used in these posts can reasonably be done with just pencil-and-paper (and a little patience). For each kind of computation we will give you at least one fully worked example—often several—and tricks to help save time and notebook paper.

Most of the math we will do is elementary, though some higher-level concepts do appear. This series assumes the reader is familiar with polynomial and matrix arithmetic as well as finite fields and their simple extensions.

Having some knowledge about elliptic curves will be helpful, but the needed formulas are provided and can be used even if you are unfamiliar with them.

While this series is intended to show that even a complex construction like PLONK can be done on paper, you might want to use a computational helper like WolframAlpha to move through the posts more quickly, if you wish.

In this first post we will show you how to choose parameters, run a trusted setup, and convert a statement into a PLONK-style circuit by hand. The next post will show you how to create a proof, and in the final post in the series we will verify the proof.

This article will explain how to execute a PLONK zero-knowledge proof system completely by hand.

You know how data structures and algorithms are pretty much Computer Science 101? They’re fundamental to just about everything in the field. Well, polynomials are just as fundamental to zero knowledge proofs (ZKPs).

In case you need a primer, ZKPs let us prove a fact without revealing the fact. You can read my [ZKP 101 post](https://www.zkcamp.xyz/blog/what-is-a-zkp-anyway) for all the details. But before we get into level 201, there’s a bit of math and cryptography we should cover.

In this blog post, we’ll focus on the math that makes ZKPs possible: Polynomials. Why? Because they’re really helpful in three major ways:

- They can encode an unbounded amount of data
- They can encode relationships between data
- They let us efficiently check whether two pieces of data are the same


You can't understand ZKPs without understanding polynomials

Proper testing is essential for Solana development given the immutable nature of blockchain programs and the financial value they often handle. By adopting a test-driven approach, you can catch bugs early, validate your program's behavior, and ensure it functions as expected when deployed to production. 

Learn how to apply test-driven development practices to Solana program development using various testing frameworks and approaches for both on-chain and client-side testing.

Test-Driven Development for Solana Programs


In this series we try to demystify zero-knowledge proofs (ZKPs) for the rest of non-math nerds. Since writing [part 1](https://dev.to/tonyolendo/the-complete-full-stack-guide-to-getting-started-with-zero-knowledge-proofs-using-circom-and-zk-snarks-part-1-53gi), my thoughts on the subject have evolved. I’m more drawn to answering the following questions

- Can anyone be a ZK developer?
- Is there a simple path that we can define for anyone to get started in writing ZK circuits?

The simple answer to all the questions above is yes! Most assuredly, yes. How? Just learn [Circom](https://iden3.io/circom) and you’ll be well on your way.


This tutorial series explains the mechanics of the STARK proof system. It is directed towards a technically-inclined audience with knowledge of basic maths and programming.

You have 1 SOL in your wallet. You open your wallet app, enter a recipient address, specify the amount, and hit send. A few seconds later, the transaction is confirmed. But what exactly happened during those few seconds?

This tutorial breaks down the entire process of a SOL transfer on Solana, from transaction construction to consensus and finality, including:

- How your wallet constructs the transaction (account addresses, Lamports, signatures)
- How transactions are serialized and sent to the network
- The role of the System Program in processing transfers
- How validators verify, process, and include your transaction in a block
- How Solana's Proof of History and tower BFT consensus ensure transaction finality
- Transaction prioritization and fees on Solana

Understanding this process helps developers build more secure applications and provides deeper insight into Solana's architecture.
