The term “snapshot” is misleading. What actually happened was that a group of people collectively decided to take some unexplored development ideas originally proposed for Spreadcoin and to pursue them independently. The result is Helium, an alternative to the current Spreadcoin development track. A copy of the Spreadcoin public ledger was made (by virtue of calculating the UTXO set at an agreed block height), giving all existing Spreadcoin holders an initial Helium balance equal to their Spreadcoin balance. The Helium group chose to initialise the project using a more recent clone of Dash.
