Recently, the NFT market and second-layer network Zora announced a proposal aiming to introduce Spark as a new name for a fractional unit of one millionth for Ethereum. This innovative move chose a unique Unicode symbol '✧' to represent the Spark unit. According to the Zora team's explanation, the ratio between 1 Spark and 1 Ethereum (ETH) is 0.000001, with 1 ETH equivalent to 1 million Spark. Zora plans to upgrade its mobile app testing to a native Spark experience in the coming weeks, further driving the application of this unit in the cryptocurrency field.
