 breach. In June 2016, an anonymous hacker exploited a smart contract running on the Ethereum network to syphon approximately $60 million of Ether held by The DAO, a distributed autonomous organization, into a segregated account. In response to the exploit, most participants in the Ethereum community elected to adopt a “fork” that effectively reversed the exploit. However, a minority of users continued to develop the original blockchain, referred to as “Ethereum Classic” with the digital asset on that blockchain now referred to as ETC. ETC now trades on several Digital Asset Trading Platforms. A fork may also occur as a result of an unintentional or unanticipated software flaw in the various versions of otherwise compatible software that users run. Such a fork could lead to users and miners abandoning the digital asset with the flawed software. It is possible, however, that a substantial number of users and miners could adopt an incompatible version of the digital asset while resisting community-led efforts to merge the two chains. This could result in a permanent fork, as in the case of Ethereum and Ethereum Classic.

In addition, many developers have previously initiated hard forks in the Blockchain to launch new digital assets, such as Bitcoin Cash, Bitcoin Gold, Bitcoin Silver and Bitcoin Diamond. To the extent such digital assets compete with Bitcoin, such competition could impact demand for Bitcoin and could adversely impact the value of the Shares.

Furthermore, a hard fork can lead to new security concerns. For example, when the Ethereum and Ethereum Classic networks, two other digital asset networks, split in July 2016, replay attacks, in which transactions from one network were rebroadcast to nefarious effect on the other network, plagued Ethereum trading platforms through at least October 2016. An Ethereum trading platform announced in July 2016 that it had lost 40,000 Ethereum Classic, worth about $100,000 at that time, as a result of replay attacks. Similar replay attack concerns occurred in connection with the Bitcoin Cash and Bitcoin Satoshi’s Vision networks split in November 2018. Another possible result of a hard fork is an inherent decrease in the level of security due to significant amounts of mining power remaining on one network or migrating instead to the new forked network. After a hard fork, it may become easier for an individual miner or mining pool’s hashing power to exceed 50% of the processing power of a digital asset network that retained or attracted less mining power, thereby making digital asset networks that rely on proof-of-work more susceptible to attack.

Digital asset networks and related protocols may also be cloned. Unlike
