  1. Techs of Chains

NEAR - Near Protocol

Nightshade Sharding

  • sharding is a scaling solution to increase network’s transaction per second (TPS)

  • nodes of validator are divided into groups, each group processes one part of data

  • groups can then process transactions simultaneously to produce chunks

  • a single validator produces block by assembling all chunks created

  • dynamic re-sharding adjusts # of shards based on user demand, technically limitlessly

Rainbow Bridge

  • bring ERC-20 tokens and assets from Ethereum chain to NEAR network

    • locks tokens to be sent in a Ethereum smart contract, tokens are taken out of circulation

    • give proof to NEAR network, create corresponding amount of tokens in NEAR

    • NEAR verifies the proof, and then creates 20 new DAI for me to use on NEAR.

Aurora

  • layer 2 solution on the NEAR Protocol

  • use ETH as gas fees like ETH layer 2 design

  • Aurora Engine - EVM that is compatible to Ethereum DApps deployment

  • Aurora Bridge - permissionless transfer of tokens & data between Ethereum & Aurora

USN algorithmic stablecoin

  • NEAR-native stablecoin soft-pegged to the US dollar

  • $NEAR is used to absorb the volatility of USN

  • an arbitrage smart contract allows the exchange of 1 USN to $1 worth of $NEAR

    • when USN=$0.99, people buy 1 USN and sell it for $1 worth of NEAR, making $0.01 profit

    • when USN=$1.01, people exchange $1 worth of NEAR for 1 USN, making $0.01 profit

  • back USN with a reserve fund that is greater than 100% of all USN (i.e. double-collateralized)

  • in extreme cases, reserve fund in Decentral Bank can repurchase all the USN to re-peg USN
