Auroracoin is a cryptocurrency for Iceland that is launched in February 2014. It is 50% premined and the coins will be distributed free-of-charge to all 330,000 citizens of Iceland via an airdrop starting from the midnight of 25th March 2014. Auroracoin is created as an alternative to the Icelandic krona. The movement of krona is severely restricted by the government and its value has dropped significantly against gold and the dollar since 1960. Each Icelandic national will receive 31.8 auroracoins during the airdrop. The creator of auroracoin goes by the pseudonym Baldur Friggjar Odinsson. Aurorcaoin is a clone of Litecoin.
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.
