Kogarashi Roadmap 2023
We are building a trustless oracle blockchain on top of modern design infrastructure. Our blockchain data structure adapts to the latest cryptographic scheme both simple to use and high performance compared with traditional blockchain. We will release our blockchain at the end of this year. On the way to the first version of the blockchain, we would like to share what kind of functionalities we implement and the research we do.
Overview
Our goal is to achieve a public IoT blockchain. IoT blockchain needs to support privacy-preserving and scaling transactions for limited resource devices. We realize these requirements by implementing modern design blockchain. Traditional blockchains are not adapted to process latest cryptographic scheme as in zero knowledge proof, homomorphic encryption and so on. We support these functionalities as built-in and replace legacy blockchain data structure with optimized one.
We have three milestones this year. The first is for privacy, the second is for scaling and the last is for combining them. Each milestone takes about three months. We write a white paper about IoT verification and develop its protocol in parallel. At the end of this year, we launch a blockchain that verifies IoT interaction with the smart contract and supports a privacy scaling payment system.
Milestone 0 | Crypto Primitives (~5/19)
Before working on the milestone, we release crypto primitive libraries. These libraries are used for zero-knowledge proof and homomorphic encryption, and bases for privacy, scaling, and off-chain verification. Cryptographic schemes are built on a stack of technologies so far. We optimize primitives and design these libraries as customizable.
Deliverables
・Abstract Algebra
・Jubjub Curve
・Bls12 381 Curve
・ElGamal Encryption
・Polynomial Operation
・Tate Paring
We release our libraries as Rust crates, cover unit tests and write documentation.
Milestone 1 | Privacy-Preserving (~6/30)
In milestone 1, we implement a confidential transfer that hides the transfer amount. Confidential transfer consists of encrypted balance by ElGamal encryption and zero-knowledge proof verification function. Transfer functionality supports audit for Ant-Money Laundering. The concrete cryptographic scheme is in our article. Regarding the white paper, we plan to collaborate with the university laboratory.
Deliverables
・Encrypted Balance
・Confidential Transfer
・Client Wallet
・Merkle Tree Gadget
・zk Rollup Balance
・Collaboration Release
We release confidential transfer libraries as Rust crates, cover integration tests through node and wallet clients, and provide the tutorial description.
Milestone 2 | Gas Cost and Speed Scaling (~9/29)
In milestone 2, we implement zk rollup which batches off-chain transactions and reflects state transition at a time. Our blockchain supports zk rollup as default and assumes a single rollup operator for integrability. Zero-knowledge proof prevents the operator from dishonesty. the operator is appointed by auction and voting. The white paper is completed by the end of September.
Deliverables
・Rollup Verification
・Operator Node
・Off-Chain Transactor
・White Paper Submision
We release zk rollup libraries as Rust crates, cover integration tests through node, operator and wallet clients, and provide the tutorial description. We post outline of IoT verification.
Milestone 3 | Launch Blockchain (~12/22)
In milestone 3, we combine privacy and scaling technologies. We participate in academic conferences, publish a white paper and implement a prototype of IoT verification smart contract. The blockchain that supports these functionalities is launched as a parachain of Polkadot.
Deliverables
・Privacy-Preserving Rollup
・Trustless Oracle Smart Contract
・Publish White Paper
・Launch Blockchain
We release privacy-preserving rollups as Rust crates, cover integration tests and provide how to use these functionalities. We publish our white paper.
About Kogarashi
Kogarashi is an IoT public blockchain based on a modern design blockchain that supports privacy-preserving rollup and IoT verification. Our goal is to create a new concept blockchain instead of copying Bitcoin and Ethereum. Our philosophy is trustless, simple to use, and decentralized, useful based on academic facts.
