//Ethereum has set standard for tokenization
ERC-20 =>worth same of all token,consists of 6 key token function(totalSupply,transferFrom,balanceOf,approve,allowance,)
ERC-223 => address key flaw of ERC-20,require half the gas ERC-20
ERC-771 =>NFT,one token can be worth a different value then another token
ERC-777 => central registry to make smart contract functions easy to verify. It also establishes an entirely new set of functions rather than using the same ‘transfer’ and ‘approve’
ERC-820 =>The registry makes it possible for anybody to “examine” a smart contract address and check the functions that it supports
