NOTE: This is a very early version of the SkyeKiwi Protocol. It is in heavy development. We will not advise anyone to use in production environment yet.

A fun background story behind our logo

Little do people know that among all Greek letters, Sigma is a special one. Not only because it’s the Greek for S and S for SkyeKiwi(duh..), but also because it’s the only Greek letter that can be written in three ways: uppercase “Σ”, lowercase “σ” and lowercase in word-final position “ς” and English likely adopt “ς” as “S” (they do look alike, right?). We make our logo to honor the Greeks’ letter Sigma but intentionally leave out the “ς” ( at a word-final position :) ), to keep this a secret (Shhhh... ). To read more on this fun Greek fact. Link

Introduction

What is SkyeKiwi?

SkyeKiwi is using a combination of various well-developed cryptographic schema to create a solution of securely sharing information in blockchain networks. The capacities of blockchain networks will be significantly enhanced when programable secrets can be processed through a decentralized network. We believe an innovative and unique new economic model will be created when secrets are processed on blockchains.

The SkyeKiwi Protocol client-side library is an early experimental library that is capable of sharing files of arbitrary size and type to thousands of people over a public IPFS network.

How does it work?

The SkyeKiwi Client Library reads in files/FormData in binary stream, divide them in chunks, generate a random sealing key of 32 bytes and symmetrically encrypt these chunks with the sealing key. Later on, a list of all CIDs and the sealing key will go through a Threshold secret sharing library then encrypted with the according public key of recipeints and pushed to a public IPFS network. The encrypted key shares will be composed into a metadata file and can be securely publicized. It will be stored on IPFS then publish the CID to a smart contract.

Installation & Testing

Full Environment Setup

Install Node.js

please reference to Node.js Website

• We recommend you to install yarn as an alternative to npm . Simple run npm install --global yarn

• The repo is tested with nodejs version 14.6.0 , to check on your nodejs version node -v , to switch version of node, I recommend using n by TJ.

Install

Please refer to the package/driver/e2e.spec.ts folder which contains test cases for common useage.

UPSTERAM

const registry = new SecretRegistry(mnemonic, {});

const file = await setup(content);
const sealer = new DefaultSealer();

sealer.unlock(mnemonicToMiniSecret(mnemonic));

const encryptionSchema = new EncryptionSchema();

encryptionSchema.addMember(sealer.getAuthorKey());

const result = await Driver.upstream(
  file, sealer, encryptionSchema, registry
);

DOWNSTREAM

let downstreamContent = new Uint8Array(0);
await Driver.downstream(
  vaultId1, [mnemonicToMiniSecret(mnemonic)], registry, sealer,
  (chunk: Uint8Array) => {
    downstreamContent = new Uint8Array([...downstreamContent, ...chunk])
  }
);

UPDATE ENCRYPTION SCHEMA

const result = await Driver.updateEncryptionSchema(
  vaultId1, newEncryptionSchema, [mnemonicToMiniSecret(mnemonic)], storage, registry, sealer
);

GENERATE & VERIFY PROOF OF ACCESS

const sealer = new DefaultSealer();
sealer.key = mnemonicToMiniSecret(mnemonic);

const sig = await Driver.generateProofOfAccess(
  vaultId1, [mnemonicToMiniSecret(mnemonic)], registry, sealer,
  new Uint8Array([0x0, 0x1, 0x2, 0x3])
);

// should equals true
Driver.verifyProofOfAccess(sig)

Run Test

1. Clone this repo to your local environment & install dependencies

git clone [email protected]:skyekiwi/skyekiwi-protocol.git
yarn

2. Create .env files at the project home directory and write your seed phrase to it

SEED_PHRASE = 'xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx'

NOTE: Use "//Alice" for seed (when the SkyeKiwi Network is still in --dev mode. ) Should be updated in the next few weeks.

3. Run Tests. The process can take somewhere between 3minutes to 10 minutes, depends on network connection.

yarn test

5. Relax. The test should be able to finish within 5 minutes.
