 the modified software. The effect of such a fork would be the existence of two versions of SOL running in parallel, yet lacking interchangeability. For example, in September 2022, the Ethereum Network transitioned to a proof-of-stake model, in an upgrade referred to as the “Merge.” Following the Merge, a hard fork of the Ethereum Network occurred, as certain Ethereum miners and network participants planned to maintain the proof-of-work consensus mechanism that was removed as part of the Merge. This version of the network was rebranded as “Ethereum Proof-of-Work.”

Forks may also occur as a digital asset network community’s response to a significant security breach. For example, in July 2016, Ethereum “forked” into Ethereum and a new digital asset network, Ethereum Classic, as a result of the Ethereum Network community’s response to a significant security 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 validators abandoning the digital asset with the flawed software. It is possible, however, that a substantial number of users and validators 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.

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
