Cairo is known as an alt VM which is zk-friendly and allows developers to enjoy super efficient STARK proofs for the underlying computation while writing in a high level language. In this post, we’ll convince you that Cairo is also a great language to write in, with exciting features and tooling that will make your…

Today, we are excited to announce a new web-based playground for Cairo! Cairo is quickly becoming the go-to language for writing provable programs. That’s why we are thrilled to introduce a brand new playground app, purpose-built for trying and learning Cairo. Cairo Playground is the best place to see Cairo in action. The default interface…

The Starknet developer experience has transformed over the past year, marked by the exciting shift from Cairo Zero to the more advanced, Rust-like Cairo. This evolution elevated the experience with enhanced security and usability, and also garnered positive feedback from the community. First published on the Starknet website, a recent survey of 92 Starknet developers…

StarkWare recently announced the creation of a new Cairo Verifier in collaboration with Herodotus, which will enable developers to create highly customizable L3 appchains on Starknet soon. Learn more about the Cairo Verifier, why we need it, and how the verifier is technically implemented with Raz, Product Manager at StarkWare, and Marcello, CTO of Herodotus.…

Cairo 2.6.0 was just released. This version involves a Sierra upgrade to v1.5.0, which means contracts written with v2.6.0 are only deployable on Starknet ≥ 0.13.1. The testnets upgrades are planned for March 5’th and 6’th (Sepolia and Goerli correspondingly), while the mainnet upgrade is planned for approximately one week later. As usual, you can continue…

Join us for an enlightening installment of the Scalability Series, as we dive into how StarkWare is revolutionizing Ethereum’s scalability through innovative technology.   Cairo: The Future of Ethereum Scaling   Inspired by Rust: Cairo is a programming language designed with provability and performance in mind, inspired by the robustness of Rust. Simplifying STARKs: It…

Starknet is a Validity Rollup that leverages the Cairo VM, purposefully designed to optimize the efficiency of Validity proofs. In order to unlock secure and decentralized scaling for Ethereum, Validity Rollups make the verification of batches of transactions vastly more efficient than their naive re-execution. Specialized nodes (called Sequencers) on Layer 2 (L2) bundle transactions…

Developers are expanding their skills to include Cairo, driven by Starknet’s increasing prominence. Solidity enabled globally interoperable smart contracts but required extensive computation repetition. Cairo’s efficiency stems from its ability to create verifiable transaction execution proofs using a single machine. Both Cairo and Solidity are smart contract languages, but their functionalities and principles are distinct.

Join us for an enlightening session of STARK @ Home, where we are honored to have Vitalik Buterin share his insights on the advent of new programming languages. In this session, we dive deep into Cairo 1.0, discussing its inception, the principles one should consider in the creation of a new language, and the unique…

Cairo 1.0 is open source! This is only the first step towards open-sourcing the StarkNet stack. We now present a first look into the Cairo 1.0 compiler. You can now start experimenting with basic Cairo 1.0 code Cairo 1.0 at its core is very similar to Rust Consider it a first taste, not a release. More improvements…

Cairo 1.0 is the first major release following the introduction of Cairo two years ago Cairo 1.0 will give developers a safer, simpler, more usable programming language At the heart of Cairo 1.0 will be Sierra, an intermediary representation layer that promises greater long term stability for Cairo programs Sierra advances Cairo to serve in a permissionless network:…
