Articles that explain how blockchain technology works and how it powers cryptocurrencies securely.
What is a liquidity pool: at its heart, a liquidity pool is a pot of tokens locked in a smart contract. These pools let people trade without a central exchange by acting as the counterparty for every trade. Instead of matching buyers with sellers, the pool itself supplies the tokens to trade against. That simple…
What is API in Crypto? At its simplest, an API is a tool that lets one program talk to another. In the world of cryptocurrency, APIs let wallets, exchanges, price trackers, and bots fetch and send information. They are the pipes that carry prices, balances, transaction details, and more. Without APIs, apps would not be…
Testnet and Mainnet are those two worlds. One is for practicing, experimenting, and fixing bugs. The other is where real value moves and real people rely on the network. In the paragraphs that follow, we’ll walk through how they work, why developers use them, and what you should know as a user or builder. Understanding…
Reflect with me Money and trust are closely tied. When you hand cash to a friend, you trust them. When you move crypto, someone or something must make sure the transfer is real. That “someone” can be a bank, but in crypto we often rely on a network of equals. That idea—people dealing directly with…
dApp — that’s the short name for a decentralized application. At a simple level, a dApp does something similar to a regular app: it may let you send messages, trade tokens, or play a game. The big difference is where the app’s rules and data live. Instead of one company keeping everything on its servers,…
Staking in Crypto is an activity that lets people earn rewards by helping secure a blockchain. You lock up — or “stake” — coins and, in return, the network pays you a small reward. It is one of the main ways people earn passive income with staking. But like any financial choice, it has trade-offs….
Gas Fees are the small payments that make Ethereum work. They reward the people and machines that run the network. They also ration the network when many people want to use it. Understanding them helps you avoid overpaying and keeps your transactions smoother. What are Gas Fees? Gas Fees are payments you make to process…
Layer 1 vs Layer 2 is a phrase you’ll hear a lot. The short way to say it: Layer 1 is the main blockchain — the foundation. Layer 2 sits on top, helping things move faster and cost less while the base layer keeps the final record. In the next sections we’ll walk slowly through…
Validator nodes are at the heart of many modern blockchains. They validate transactions, help secure the network, and sometimes make decisions about upgrades. Below I lay out the core responsibilities of a validator, the importance of validator in blockchain systems, how they protect networks, and what it looks like to run or pick a validator….
Tokenomics starts with the token itself and grows into the whole project. It is not just numbers on a page. It is incentives, plans, and rules. If you learn a few simple checks, you can judge crypto projects more clearly. This article breaks the topic into pieces. No heavy math. Just clear steps you can…
