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.
Harmony’s open, decentralized network is enabled through the use of the native protocol token - Harmony ONE. The token incentivizes and rewards a variety of participants including developers, validators/stakers, investors, and community members who develop, secure and govern the network. In order to use the network, users pay a small transaction fee denominated in the native Harmony token. Harmony’s scalable, high-throughput protocol is powered by a native token which is used for various forms of payment and participation in the protocol (staking, transaction fees, voting & governance). Harmony uses blockchain to align incentives of different stakeholders, developers and businesses while allowing them to build open marketplaces of fungible and non-fungible tokens and assets. Furthermore, the upcoming application of zero-knowledge proofs will allow Harmony to become a data sharing platform that can overcome the conflicting problem plaguing many information and data markets: that individual market participants’ have mutual distrust to share data but strong desire to acquire data themselves. The Harmony token will function in the following aspects of the protocol: The token is used for staking, which is necessary to participate in the POS consensus & earn block rewards and transaction fees. The token is used to pay for transaction fees, gas and storage fees. The token is used in voting for on-chain governance of the protocol.
