 Early June 2018 community member Mark (known as '​toaster'​ at that time) announced that he would fork the Sia codebase and start his own project based on Sia called Hyperspace with a new currency called Space Cash (XSC). On the first of July all addresses on the Sia blockchain would be credited one tenth of the amount of siacoins they held in Space Cash. The total size of the airdrop was 3.5 billion Space Cash. A snapshot of the Sia blockchain was done on block 161,358 for a 10:1 (SC:XSC) ratio airdrop. Early June 2018 community member Mark (known as '​toaster'​ at that time) announced that he would fork the Sia codebase and start his own project based on Sia called Hyperspace with a new currency called Space Cash (XSC).

-At the launch of the network an additional 600 million Space Cash was generated and distributed among developers and contributors to the Sia project. Developers NickH (Luxor mining), darval (Open source mining pool), RBZL (siasetup.info),​ Fornax (pixeldrain.com),​ drexel (siadrive), tbenz9 (Sia developer / documenter),​ hakkane (siastats.info),​ sebdude (siaberry), bryan (easysia.com) and atreides (hyperspace ​contributor) received 54 million time locked Space Cash. Contributors CryptoHaag, moonshot, Wibs, Aura89, MasterHW and Spacing Radar101 received 10 million time locked Space Cash. These users are now all moderators in the Hyperspace discord server. The distributed coins would be locked until Hyperspace block 157,680 which should be mined roughly three years after the genesis of the blockchain.+At the launch of the network an additional 600 million Space Cash was generated and distributed among developers and contributors to the Sia project.

-After a long period of debate it was concluded that the best solution to the [[development:​obelisk|]] debate was to slightly modify the mining algorithm in order to fork all competing ASICs off the network. Starting from Sia version 1.3.6 the Obelisk SC1 will be the only miner able to mine Sia at profitable hash rates. Version 1.3.5 was released for the people who would prefer to stay on the other side of the fork compatible with all ASIC miners. However, the developer overlooked the impact of the reduced hashrate and does not include a difficulty adjustment on version 1.3.6, potentially causing a very long blocktime after fork so version 1.3.7 was released 9 days before the expected fork date. The fork will commence ​on block 179,​000 ​and the main chain will continue ​with Sia version 1.3.7 and above.+After a long period of debate it was concluded that the best solution to the [[development:​obelisk|]] debate was to slightly modify ​the nonce of the mining algorithm in order to fork all competing ASICs off the network. Starting from Sia version 1.3.6 the Obelisk SC1 will be the only miner able to mine Sia at profitable hash rates until other manufacturer release new competing ASICs. Version 1.3.5 was released for the people who would prefer to stay on the other side of the fork compatible with all ASIC miners. However, the developer overlooked the impact of the reduced hashrate and does not include a difficulty adjustment on version 1.3.6, potentially causing a very long blocktime after fork so version 1.3.7 was released 9 days before the expected fork date. The fork had been activated ​on block 179,000, which took about 14.6 hours to be mined because of a bug in the difficulty adjustment algorithm, causing it to need a block to be mined before the difficulty adjustment kicks in to significantly drop the difficulty. The main chain continues ​with Sia version 1.3.7 and above.
