Blockchain lending essentially builds on the timeless peer-to-peer model,making the entire process more seamless and reducing the amount of time the process takes.
ERC-20 is a technical standard used for smart contracts on the Ethereum blockchain for implementing tokens. It defines a common list of rules that an Ethereum token has to implement, giving developers the ability to program how new tokens will function within the Ethereum ecosystem.
The main goal of this ERC223 token standard proposal is to prevent tokens loses during a token transfer. ERC223 wants to treat the token transfer in the same way as Ether transactions which means to handle each transaction as an event. This can prevent any token lose.
ERC-721 defines a minimum interface a smart contract must implement to allow unique tokens to be managed, owned, and traded. It does not mandate a standard for token metadata or restrict adding supplemental functions.
