What is Orand?

Orand is an Elliptic Curve Verifiable Random Function (ECVRF: https://datatracker.ietf.org/doc/html/draft-irtf-cfrg-vrf-05) as a service that offers high performance, zero latency and 30 times lower cost than current providers. Orand offers on-chain verification and pseudorandom for projects that seek integrity and transparency in their features with a wide variety of case studies from card games and MMORPG to NFT collectibles.

Unique Features



A distributed system with many participants/nodes will join to generate randomness by using Multi Party Computation (MPC).



An ECVRF performs on input the previous randomness and it also requires half of participants to join the process.

High throughput

High throughput

Game server could request randomness from the Orand system. The result will be provided as soon as half of participants participate in the protocol.

Fault Proof

Fault Proof
