Understanding the Role of Randomness in the Metaverse
The metaverse operates on seemingly random values generated by random number generators (RNGs). However, these values are not truly random but rather the results of fixed equations. While this may be sufficient for certain applications, it can lead to issues in systems that require true randomness. Random numbers play a crucial role in various applications such as games, security systems, DAO governance, and NFT generation.
The Importance of Random Numbers
Random numbers are essential for maintaining variety and effectiveness in systems. Games that lack access to randomly generated numbers become repetitive and dull. Security systems relying on easily guessed codes offer little protection. Any system that requires diversity but lacks it cannot function effectively.
Many RNGs are actually Pseudo RNGs (PRNGs) that provide outputs based on fixed equations. Although these outputs may appear random, they lack true randomness. The quality of PRNGs can vary significantly, impacting applications with higher stakes or multiple use cases.
The Issue with PRNGs
PRNGs can exhibit predictability due to simple equations or external influences, which can lead to tampering. Additionally, many PRNGs lack verification mechanisms, making it impossible to confirm if the provided number is genuine. This poses a challenge for blockchain systems built on transparency and trustlessness.
Furthermore, not all PRNGs are suitable for every application as some are designed for specific Web3 functions.
The Search for True Randomness
While PRNGs offer convenience and affordability, they suffer from centralization and potential tampering. True randomness comes at a higher cost and may result in system-wide downtime if any issues arise.
Decentralization and Reliability
Using an RNG that doesn’t meet the decentralization, verification, and security requirements of an application can be disastrous. The collapse of Axie Infinity due to a security breach serves as a reminder of the importance of selecting the right RNG.
The ideal RNG should be unpredictable, tamper-resistant, verifiable, decentralized, and continuously available. When choosing an RNG, consider factors such as randomness, verification capabilities, security against tampering, and avoidance of single point failures.
Hot Take: Ensuring the Best Support for Blockchain Applications
As blockchain developers continue to innovate and expand their applications, it is crucial to provide the best possible support. The selection of a reliable and secure RNG is vital to maintain user confidence and avoid technical failures with significant repercussions.
