Remme

Blaize completed following projects for Remme:

• Remme Chain
• Remme Atomic Swap Bridge
• Remme Multisig Wallet
• Remme Client

REMME CHAIN

Requirements:

• to find a faster and more scalable blockchain (with smart contracts support and implementation of a new consensus model along with internal economics);
• using  smart contracts’ supporting platform for logic staking implementation
• rebuild reward distribution mechanism and resources management system

Challenges we faced:

• keep up with various features on EOSIO;
• maintain the high throughput while working within fairly limited blockchain capabilities;
• constant patches integration from the EOSIO blockchain.

Solution:

• implementing the entire logic and economy of Remme protocol basing on the robust architecture;
• creating a new EOS-based blockchain with more fair rewards distribution.
• correct branching strategy for merging updates from EOSIO repository

Technologies we used:

• С++
• EOS blockchain
• WASM
• JavaScript

REMME ATOMIC SWAP BRIDGE

Requirements: 

• creation of the two-way token transfer;
• adjustment of the swap mechanism between Ethereum and Hyperledger networks;

Challenges we faced: 

• Remme’s ERC20 tokens have to be transferable to the native blockchain and vice-versa.
• Lack of native interoperability between Hyperledger and Ethereum blockchains makes direct asset transfer impossible.
• The bridge between two blockchains should have the highest level of performance, security and reliability.

Solution:

We compiled information on existing solutions, and together with the Remme team decided to use atomic swap technology.

• implementation of non-standard solutions in order to ensure stable and safe work of the migration service;
• adjustment of fast and reliable token transfer into Ethereum tokens (ERC20 standard)

Technologies we used: 

• Solidity
• Hyperledger Sawtooth
• Node.js
• MongoDB
• React.js
• Python

REMME MULTISIG WALLET

Requirements:

• creation of a smart contract management system, requiring the consent of several users (Ethereum network based);
• creation of a Telegram bot with transactions and notifications storage.

Challenges we faced: 

• client required reliable and highly secured storage;
• fork issue on the Ethereum blockchain (transaction can be confirmed on one chain, yet dropped by another, while the client needs to see the actual data).

Solution:

• implementing multisig wallet technology on the Ethereum network;
• providing reliable encrypted storage for private keys;
• users’ wallets configuration with the Telegram bot

Technologies we used:

• Solidity
• Node.js
• Electron.js
• MongoDB
• Python
• Telegram API

REMME CLIENT

Requirements: 

• creation of an application for Android and iOS with two-factor user authorization basing on the Remme blockchain;
• add user data protection (password, fingerprint, face recognition).

Challenges we faced: 

• Client software have to integrate with secured wallet;
• The solution should be well optimized for use by multiple corporate users;
• The application should be optimized for three customers whose business processes differed.

Solution: 

• development of an open-source solution using React Native framework.

Technologies we used: 

• React Native
• Hyperledger Sawtooth
• Jest
