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.
The key to Space Chain is to deploy all blockchain nodes on satellites so as to bring blockchain technology into space, adding a new dimension to blockchain’s core concept of distributed ledger by making use of space technology and advantages of space resources. As a space blockchain platform featuring data collecting, computing, application and storage, Space Chain uses satellites as its blockchain nodes for realizing direct on-satellite data processing and secure in-space data storage through cryptographic technologies such as quantum communications. Different from ground-network-based blockchain technology, Space chain provides a broader coverage and is based on a network of LEO satellites for achieving broad-based connectivity so that anyone and anything could become the user of blockchain technology anywhere and anytime.
