ERC – 721, a new standard for ethereum and startup use this standard to manufacture digital collectible kitties or pets for sell in market place. Have you wonder why cryptopets such as #cryptokitties is collectible and is unique while there is no difference between your ethereum coin and my ethereum coin?
What is ERC: Non-fungible Token Standard #721?
Non-fungible means unique. ERC is acronym of Ethereum Request for Comments. A standard allows for the implementation of a standard API for creating non-fungible tokens. To whom not familiar, ethereum, when launched during ICO, is using ERC-20 which ethereum coin can be broken down into smaller portion such as 0.000001. As you know, in coin, we don’t differentiate it by serial number. Government only use “serial number” to track the note and not on coin. Hence, there is no way to distinguish or trace your coin and my coin. This behavior is same in Ethereum coin. Startup has found a way to use ERC-721 to create a unique and traceable coin in ethereum blockchain technology. This is a break through in blockchain technology.
What has ERC-721 better over ERC-20?
In recent weeks, startup company named Cryptokitties launched on 23 Nov, the main product is selling digital collectible kitties. Each digital kitties is unique and you cannot slice them into smaller piece and sell them. It is a must to sell them as a whole unit.You can’t buy a quarter of a cat and if you could it probably would be worthless. This is the main difference between ERC 20 vs ERC 721. Besides, each kitties is given a catribute which is again one of its kind. This two make an advancement in ethereum protocol which able to make item derived from ERC-20 and add more uniqueness into the collectible item.

In short, ERC 721 has opened up of potential “manufactured collectible” which large company can create such a unique collectible item for its fans for their collections. I already can imagine brand such as Rolex or Tesla can build a digital collectible item of their product for their fans. The possibilities are limitless. Startup can use the ERC-721 standard to create a collectible item which is unique to be tracked in standardized wallets and traded on the secondary marketplace. This ability made Ethereum maybe the next coin to go into the major exchange.
