It has been quite a whirlwind. While it was only four months ago that we announced Sui to the world, it feels like several lifetimes have since passed. Many crypto and blockchain community members — us included! — have witnessed repeated ups and downs. Yet, we believe these moments of extreme market volatility represent the best opportunity to hunker down and build the infrastructure to onboard web3’s next billion users.

Today, we are ready to announce that Sui’s Incentivized Testnet will kick off in August. This stage is the next step towards launching a secure, performant, and decentralized blockchain network.

Our team has been hard at work since our initial announcement. We:

• Finalized the design and implementation of Sui Move, an improvement on the original Move instantiation in Diem optimized for ergonomic and highly parallelizable code

• Open sourced Narwhal/Tusk consensus and integrated it with Sui to support shared object transactions

• Released a public DevNet for early Sui builders and partners

• Shipped the Sui Explorer that leverages Sui’s object-centric data model to display transactions and their effects in a human-readable fashion

• Launched fullnodes to an enthusiastic response from our community, with more than 5,000 nodes running in 65 countries and 271 cities and counting!

Speaking of our Sui community, we would like to take this opportunity to express our gratitude for your engagement, thoughtfulness, and commitment. We appreciate our partners, investors, DevNet builders, fullnode operators, GitHub contributors, Discord moderators and participants, social media followers, and everyone else who has dedicated their time and energy to Sui — we are fully dependent on you! Our community has repeatedly shown the value and importance of public feedback throughout the early phases of a major undertaking like Sui.

Sui’s testnet will steadily progress from the first multi-entity Sui network toward a decentralized mainnet operated by an evolving set of independent and distributed validators. The testnet will gradually introduce and stress-test the key features, mechanisms required for a decentralized, production-ready Sui network. The testnet aims to validate our designs, test our validator, full node, wallet, and developer toolchains, and build operational experience with a cohesive group of high-quality operators. We will graduate from Testnet to mainnet when we are fully confident in the security and performance of our software, have seen sustained operational excellence from our initial validators, and validate our developer experience via compelling Move-powered applications deployed on testnet.

Sui’s Testnet is organized as a series of consecutive “waves” 🌊

Each wave consists of two challenges: a “sink” (an operational challenge) or a “swim” (a Move-based Sui developer challenge).
