Zordle
Zordle is a privacy-focused word-guessing game that utilizes zero-knowledge proofs to ensure that the words being guessed by a player are kept secret from the verifier. The game is similar to the popular word-guessing game Wordle but with an added layer of security.
To play Zordle, a player and a verifier first agree on a shared grid of letters. The player then tries to guess a word that can be formed using some of the letters from the grid and uses a zero-knowledge proof to prove to the verifier that they know a word that can be formed from those letters, without revealing the word itself.
The zero-knowledge proof used in Zordle is based on the Halo 2 ZK proof system, which is a recent development in the field of zero-knowledge proofs that are designed to be efficient and scalable. By using Halo 2, Zordle is able to provide strong privacy guarantees without compromising performance.
Zordle is a web app that can be played on any modern web browser, and it is available for free. It was developed by a team of researchers at the University of California, Berkeley, and it is intended to be used as a tool for teaching and exploring zero-knowledge proofs, as well as a fun and engaging game.
Features:
- Privacy: Zordle uses zero-knowledge proofs to ensure that the words guessed by the player remain private, even from the verifier.
- Halo 2 ZK Proofs: The game is built on top of the efficient and scalable Halo 2 zero-knowledge proof system.
- Multiple Difficulty Levels: The game offers multiple difficulty levels, ranging from easy to hard, allowing players to challenge themselves and improve their skills.
- Time Limits: Each round has a time limit, adding an element of urgency and excitement to the game.
- Hint System: Players can use hints to reveal one of the letters in the hidden word, helping them to narrow down the possibilities.
Tips to Win:
- Start with the most common letters: The English language has a few letters that are used more frequently than others. Starting with these letters can increase your chances of finding the hidden word.
- Look for patterns: Try to identify common letter combinations and patterns that may appear in the hidden word.
- Use the hint system wisely: If you are stuck, use the hint system to reveal one of the letters in the hidden word. This can help you narrow down the possibilities and increase your chances of guessing the word correctly.
- Practice, practice, practice: Like any game, the more you play Zordle, the better you will become at it. Keep practicing and challenging yourself with harder difficulty levels to improve your skills.
