Bitcoin Knots has overtaken a quarter of the Bitcoin network's nodes, climbing from 19% to 25.45% in just five days, according to Coin Dance node metrics as of September 14, 2025. The alternative Bitcoin client has seen its node count surge by 47.60% in the same period, far outpacing the modest growth of Bitcoin Core.
Core v30 Sparks Backlash
The rapid adoption of Knots is largely attributed to growing dissatisfaction with Bitcoin Core's upcoming v30 release. Key proposed changes include eliminating the 80–90-byte OP_RETURN limit and allowing larger data per transaction. Opponents argue this could turn Bitcoin into a spam magnet, complicate node operator filtering, and potentially destabilize nodes running in cloud environments.
In contrast, Knots enforces strict policy rules and automatically discards unwanted transaction baggage, appealing to users who prioritize Bitcoin's monetary properties and network cleanliness.
Node Count Comparison: Knots Boom vs Core Stagnation
On September 9, Bitcoin Core had 18,758 nodes, which crept up to 19,048 by September 14—a mere 1.54% increase. Meanwhile, Knots nodes skyrocketed from 4,417 to 6,518, posting a 47.60% jump.
While Core still holds the majority of nodes, Knots' explosive growth has become a headline act, sparking debates over software diversity and governance within the Bitcoin ecosystem.
Sybil Attack Allegations
Some Bitcoin Core loyalists have accused Knots operators of padding their numbers through a Sybil attack, alleging that nearly 40% of Knots nodes could be clones or fakes. However, these claims have been met with widespread skepticism, and Knots' growth has continued unabated.
The controversy underscores a broader shift: node diversity is no longer optional but a critical power play in Bitcoin's network evolution. Whether this trend is a fad or a lasting change remains to be seen, but the message is clear: the days of a single dominant client are being challenged.
