Gas is one of the two coins created by Neo Foundation. Gas is used as a processing fees for Neo coin. Neo hashing algorithm is Proof of Stake (PoS), where blocks processing power depends on the amount of tokens held by miners instead of the Proof of Work method which depends on the mining power that a miner has to create a new block. Neo holders is compensated with certain amount of Gas every month, is a similar concept to the ether gas and is used as a power for transaction (transaction). It is a coin that is paid as compensation of a concept of interest generated by PoS mining. At the beginning of the release, about one Neo was paid per day with 1000 Neo, but it has a design algorithm that is gradually decreasing over time, which is offset by the price increase. It is a coin that is closely related to Neo, walking along the path of the companion with the rise of Neo, and it forms a necessary relationship that the movement must be moving in a fluid manner.
'Tael is a digital token for safe consumer products. Thanks to its ability to be seamlessly integrated by third parties, it allows for a wide token use-case through interchangeability of the loyalty tokens on the blockchain. Tael’s first use-case is seen in Techrock’s safe consumer products ecosystem. Techrock applies banking-level, tamper-proof NFC smart-labels to consumer goods, pairing them with their digital representations on the blockchain. Consumers ‘touch’ the label with their smartphones to verify a product’s authenticity, discover the product’s journey along the supply chain, and be rewarded for their purchase. Techrock protects products where authenticity matters, such as infant formula, cosmetics, alcohol, and supplements. Tael tokens are used in the loyalty point ecosystem to reward consumers and encourage behavior in the Techrock channel while generating unique data for all companies in the value chain. Tael’s vision is to bring blockchain based payments into the mainstream, across Asia and beyond.'
