Pyth Entropy has officially launched on the EVM networks, providing a random number generation (RNG) solution commonly used by blockchain applications, such as games, non-fungible tokens (NFT) drops, and decentralized prediction markets, providing reliable require source of information. randomness to ensure fair and unpredictable outcomes.
The protocol uses a two-party commit-reveal mechanism, a cryptographic technique that allows the generation of random numbers without the need for mutual trust. During the period called the “Commitment Phase,” each party generates a secret random number, hashes it, and commits the hash to the blockchain. In the “Reveal phase”, the ciphers are revealed and verified against the recorded hashes, with the final RNG obtained by hashing the two revealed ciphers together.
Pyth Entropy’s design includes a pre-commit to multiple random numbers, reducing transaction requirements, and it includes the chain’s block hash to increase randomness. According to the announcement, the security is comparable to other RNG methods such as Chainlink’s VRF.
Developers can integrate Pyth Entropy with minimal coding effort, and the pull design, similar to Pythnet Price Feeds, enables communication over HTTP instead of the blockchain, significantly increasing transaction speed. The protocol is already used by FLAP and Fungible Flip, two applications from Blast blockchain, and SlashToken, from Chiliz Chain.
