While Bitcoin's increasing hashrate and adoption present a challenge to SHA-256, the sheer scale and entrenched infrastructure surrounding SHA-256 (particularly in proof-of-work cryptocurrencies) creates a significant barrier to replacement. Furthermore, the technical complexity of transitioning existing blockchains to a different consensus mechanism is substantial, and unlikely to occur rapidly enough before 2027. The crowd-implied probability of 5% reflects this cautious assessment.
