Orochimaru is a full-node client of Orochi Network which was implemented in pure Rust programming language. Orochi Network isn't a blockchain but a distributed network built to perform Multi Party Computation (MPC) and Zero-Knowledge Proof (ZKP) proving from which we provide trustless and Verifiable Computation. Our mission is to establish High Performance dApp.
At Orochi Network, we believe that Verifiable Computation is a critical primitive to establish Web3 and Decentralized Autonomous Economy. However, in order to reach this stage, there are still a number of major challenges in this industry to overcome.

Our solution is to build a universal run-time environment (zkWasm) that provides Verifiable Computation. We can build up the verifiable data pipeline on top of our zkWasm to solve the correctness and availability challenges of the data.
Allowed verifiable randomness to be generated and fed to any smart contracts on EVM compatible blockchains. Orand uses Elliptic Curve Verifiable Random Function (ECVRF) to prove and verify randomness. You can learn more about ECVRF in our blog blog.orochi.network.

Verifiable randomness: We're using Elliptic Curve Verifiable Random Function (ECVRF) to generate randomness in the process described here https://datatracker.ietf.org/doc/html/draft-irtf-cfrg-vrf-05#section-5.3. Curve secp256k1 and keccak256 (Ethereum variant) was used to minimizing verification cost for smart contract.
Dispersity: A distributed system with many participants/nodes will join to generate randomness by using Multi Party Computation (MPC)
Unpredictability: A VRF will perform with the input is previous randomness and it also requires half of participants to participate in MPC
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 MPC.
Cheap and secure randomness: For the free tier, randomnesses will be given freely for the first 20,000 randomnesses every month.
Fault Proof: If the game server tries to delay the feeding process to manipulate the result, a fault proof will be committed so sue the game server.
Multi-chain: All EVM compatible blockchains can be supported
