The 2016 economic report “On the Value of Virtual Currencies” commissioned by the Bank of Canada, found three contributing components dictating a cryptocurrency’s exchange rate: The actual use of virtual currency to execute real payments. The decision of forward-looking investors to buy virtual currency (thereby effectively regulating its supply). The elements that jointly drive future consumer adoption and merchant acceptance of virtual currency. XAC Attention Addresses Attention Addresses are linked to AMARK consumer data and have specific rules enforced by the XAC protocol. There are two key functions of attention addresses: XAC-LOCK XAC-Lock is a feature that encourages continued consumer engagement with AMARK. The XAC sent to Attention Addresses is initially locked and becomes available after a maturation period. The XAC attention awards paid to consumers continually matures into availability as new XAC is earned from ongoing attention marketing. This process encourages engagement with AMARK as attention wallets will rarely have a zero XAC balance, giving consumers a consistent flow of value to spend within the ecosystem. XAC-BURN XAC-Burn is enforced at the protocol level. All transfers to Attention Addresses require 5% of the XAC transferred to be burned. The XAC -Burn feature is designed to align interests between merchants and consumers in the AMARK ecosystem. Anytime merchants use the AMARK platform for marketing, they are supporting the value of the XAC currency as protocol rules enforces a 5% burn. As such, merchants are effectively scaling the supply of XAC to match the demand from the ecosystem. This supply-side scaling mechanism will offset new coins introduced through block rewards and pressure the price of XAC to an equilibrium reflective of demand from the ecosystem.
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.
