Hi everyone, my name is Heorhii. Over the past year I’ve been diving deep into Aleo, exploring how zero-knowledge applications can move from theory to production. With the Aleo mainnet now live, one of the most exciting areas is cross-chain interoperability: bringing assets and data into the Aleo ecosystem in a way that is both private and compliant. https://predicate.io/ This is where Predicate comes in. Predicate is a blockchain company focused on simplifying compliance and risk management....

Hi, my name is Heorhii. I have spent the last year tracking Aleo from a builder’s point of view: what the stack enables, how the economics evolved after mainnet, and where the friction really is for developers, validators, and provers. If you are here for quick value: Aleo is not an EVM rollup with a ZK “add-on.” It is zero-knowledge by design, a new L1 with its own zkVM (snarkVM), language (Leo), and network OS (snarkOS). That is powerful, but the tradeoffs span tooling, ecosystem maturity, ...

My name is Heorhii, and in this article, I’ll walk you through how NFT standards work on Aleo and how you, as a developer, can implement them in your own projects. Unlike traditional blockchains, Aleo introduces a new dimension: privacy by default. With the NFT standard (originating from ARC-0721) and the proposed NFT Registry Program (ARC-722), developers can now build NFT collections with flexible privacy, ownership visibility, and composable features. https://github.com/ProvableHQ/ARCs/dis...

My name is Heorhii, and over the past few years I’ve been deep into building and experimenting with privacy-preserving blockchain networks. One of the most important security backbones in these networks is staking. On Aleo, staking isn’t just about earning rewards, it’s about actively contributing to the network’s security and stability. In this guide, I’ll walk you through how staking works on Aleo, the differences between native and liquid staking, and most importantly, how to perform each ...

My name is Heorhii, and in this guide, I will walk you through how transactions work on Aleo, how to create them, and how to check their status programmatically. If you are building on Aleo, mastering transactions is essential because they are the foundation for executing programs, deploying code, and transferring assets. A transaction on Aleo represents a complete operation on the network. It can deploy a program, execute a function, or simply pay a fee. Every transaction is signed locally w...

Hi, my name is Heorhii. This developer guide walks through how to write and test your first smart contract using Zama’s FHEVM, a tool that brings confidentiality to blockchain through Fully Homomorphic Encryption (FHE). If you already use Solidity and Hardhat, the workflow will feel familiar. The key difference is that you’ll be building with encrypted values, making privacy a native part of your dApp from the start. What is Zama? Zama is a company focused on privacy and cryptography. Its mis...

Hi, my name is Heorhii. In this article, I’ll guide you through one of the most important topics for building private apps on Aleo: how to handle public and private state. If you’ve worked with smart contracts on Ethereum, you're used to public-by-default data. Aleo flips that assumption and gives developers full control over what’s kept private and what can be made public. Let’s explore how this works and how to use it in real-world scenarios. Privacy on Aleo. Aleo is a layer-1 blockcha...

Hi, I’m Heorhii. If you're building with Aleo, you’re probably aiming to create apps that protect user data while staying fully verifiable. That’s what makes Aleo different from most blockchain platforms. To build with Aleo effectively, you need the right SDK for the job. In this guide, I’ll walk through the four main SDKs available for Aleo development. Each serves a different purpose, depending on your language, platform, and project type. I’ll also show how to use each one with real e...

My name is Heorhii, and if you're building private apps on Aleo, this guide is for you. Aleo introduces a new way to write applications, where logic can run privately, and only proofs are shared publicly. That means you can build apps where balances, messages, identity, or even AI inference data are hidden by default, but still verifiable. To make all this easier, the Provable SDK gives developers a JavaScript/TypeScript toolkit to interact with Aleo programs. In this guide, I’ll walk yo...

Hi, I’m Heorhii. I’ve been building smart contracts with Solidity for a while, but moving to Aleo and learning Leo changed how I think about privacy, computation, and contract design. If you’re an Ethereum developer, this guide will help you translate your knowledge into Leo, the programming language for Aleo’s zero-knowledge apps. This is not just a syntax shift, it’s a mental model shift. https://www.leo-lang.org/ 1. Execution: public by default vs privacy by design.In Solidity, every compu...

My name is Heorhii, and in this guide, I’ll walk you through how to run and understand Aleo’s snarkOS, the decentralized operating system powering ZK apps. Whether you're building applications, participating in consensus, or simply exploring Aleo’s infrastructure, snarkOS is the backbone of the network. Let’s dive in. What is snarkOS? snarkOS is the foundation of the Aleo blockchain. It verifies off-chain, zero-knowledge transactions using snarkVM and maintains encrypted state in a publi...
