white paper

FSV (File System Video), a decentralized video file system based on the blockchain, can transmit data based on GOSSIP protocol. FSV aims to provide a decentralized blockchain video publishing environment for video producers, cast streaming media copyrights with NFT technology, realize governance through DPOS mechanism, and create a new ecology for on-chain economy in the field of streaming media industry.

FSV provides a decentralized copyright registration and trading platform to fix the copyrighter according to the registration timestamp, generate the NFT blockchain copyright certificate, achieve self-governance through the decentralized DPOS mechanism, solve the problems in the field of global streaming media copyright, and promote the full protection of the interests at all aspects in the streaming media industry.


Laser Scorebeta Last Audit: 12 June 2022

Token seems to be a scam (type: rug pull scam).



Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract creator or owner is blacklisted for past scams

Contract ownership is not renounced (belongs to a wallet)

Redundant expression "this (#123)" inContext (#117-127)
Remove redundant statements if they congest code but offer no value.

Variable CosmosToken.setPairAddr(address)._pairAddress (#956) is too similar to ERC20.paireAddress (#169)
Variable CosmosToken.setFeeAddressAndPercent2(address,uint256,uint256)._denominator (#949) is too similar to ERC20.tDenominator (#167)
Prevent variables from having similar names.

CosmosToken.burnToken(uint256,string,string).fee (#925) is a local variable never initialized
ERC20._transfer(address,address,uint256).fee (#350) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Pragma version^0.8.0 (#5) allows old versions
solc-0.8.1 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
