NanoByte aims to bridge cryptocurrency to the traditional/conventional currency system, by making crypto-wallets compatible to FIAT products such as e-money, credit cards, insurance, and other investments.
NanoByte has secured support from Sinar Mas Financial Group (one of the largest conglomerate groups in Indonesia), and partnership with other institutions & parties to ensure the best crypto use-cases and offerings.
Strong competitive advantage as the world's 4th most populous country with 270+ million people and given that crypto is fully regulated as digital asset.
NanoByte also has advantages in its home country, as it is being supported by traditional financial players and crypto players throughout the country.

NanoByteToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/NanoByteToken.sol#245-263) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/NanoByteToken.sol#255)
Don't use strict equality to determine if an account has enough Ether or tokens.
