The Bitcoin network, long hailed as a beacon of decentralization and neutrality, may be inching toward another schism. On June 6, 2025, tensions escalated after Bitcoin Core developers published a statement introducing a shift toward a “minimally permissive” transaction relay policy. While the post avoided buzzwords like Ordinals or OP_RETURN, the implications sent ripples across the ecosystem. Bitcoin Update October 2025 With the changes slated for implementation by October 2025, the Bitcoin community could be heading for its most significant ideological clash since the 2017 SegWit hard fork.
What Is Changing in Bitcoin Core?

Although these transactions comply with Bitcoin’s consensus rules, Core nodes may soon stop forwarding them to the network, effectively censoring certain use cases by default at the policy layer.
One key target is the OP_RETURN opcode, a long-standing feature that allows users to insert small bits of data—up to 80 bytes—into the Bitcoin blockchain. While OP_RETURN has supported projects like Omni Layer, Counterparty, and more recently Ordinals-based NFTs, some Core developers argue it leads to blockchain bloat and should be deprioritized to preserve space for “financial” transactions.
Critics, however, see this move as an erosion of Bitcoin’s neutrality, with developers unilaterally deciding which applications are “worthy” of network resources. This slippery slope, they argue, undermines Bitcoin’s fundamental promise: permissionless innovation.
Bitcoin Knots Gains Ground Amid Policy Disputes
Enter Bitcoin Knots, an alternative full node software maintained by former Core contributor Luke Dashjr. Knots differs from Core in that it does not enforce policy-level filters unless users explicitly configure them. In essence, Knots gives node operators more control, making it attractive to those who believe Core is overstepping its mandate.
According to Bitcoin Update October 2025: Relay Policy Controversy Could Mirror 2017 Fork network tracking data, over 13% of the Bitcoin network is now running Knots, signaling more than a protest—a parallel consensus is emerging. This rise reflects growing discomfort with Core’s central influence over the Bitcoin protocol’s day-to-day behavior, especially among users who champion Bitcoin’s open and neutral ethos.
Echoes of the 2017 SegWit Schism
Bitcoin Update October 2025: Relay Policy Controversy Could Mirror 2017 Fork While this current rift has not yet triggered a hard fork, comparisons to the 2017 Bitcoin vs. Bitcoin Cash split are becoming increasingly relevant. That episode, sparked by disagreements over block size and transaction throughput, culminated in two competing chains—and two competing visions of what Bitcoin should be.
On August 1, 2017, Bitcoin Cash (BCH) forked from Bitcoin (BTC), leading to short-term price volatility but no long-term collapse. In fact, Bitcoin surged in the months following the fork, hitting $20,000 by December 2017. Meanwhile, BCH provided an alternative for those who favored larger blocks and faster transactions.
This time, the debate centers on policy vs. protocol. If Core’s changes lead to widespread transaction rejection from alternative clients like Knots, the resulting incompatibilities could pave the way for another de facto fork—or at least a splintering of user preferences and node diversity.
Potential Impact on Bitcoin Price in October 2025
If history is any guide, Bitcoin price volatility could spike around the implementation window in October. During the 2017 fork:
- BTC dropped ~5.6% on the day of the split
- Quickly recovered and surged ~49% over the following month
- Bitcoin Cash (BCH) launched around 0.0045 BTC (~$240) and surged before stabilizing
Today’s market is more mature, with institutional involvement, options trading, and futures that could both mitigate and amplify reactions. A hard divergence between Core and non-Core clients could trigger short-term uncertainty, but may also reaffirm Bitcoin’s resilience—just as it did in 2017.
Core’s Vision vs. Bitcoin’s Open Principles
Supporters of the Core proposal argue that limiting non-standard transactions enhances security, simplifies node operation, and aligns with Bitcoin’s original purpose as peer-to-peer money. Bitcoin Update October 2025: Relay Policy Controversy Could Mirror 2017 Fork They fear that excessive use of OP_RETURN and Ordinals clutters the chain, raising fees and reducing accessibility.
Opponents counter that as long as a transaction is valid by consensus rules and pays market fees, it deserves equal treatment. From their perspective, Bitcoin Update October 2025: Relay Policy Controversy Could Mirror 2017 Fork Core’s policy shift is an unwelcome return to centralized gatekeeping, where a few developers dictate acceptable usage.
This tension—pragmatism vs. principle—is as old as Bitcoin itself.
What Happens Next?
All eyes are now on Bitcoin Update October 2025: Relay Policy Controversy Could Mirror 2017 Fork October 2025, when Core is expected to roll out its new relay rules in a major software update. Node operators, miners, exchanges, and developers will face a critical decision: Which implementation to follow?
- Will Knots gain enough traction to enforce a different policy layer?
- Will miners signal neutrality, or align with Core’s vision?
- Will users demand greater control over their transactions?
Regardless of the outcome, this episode underscores a growing truth: Bitcoin’s decentralization is only as strong as the diversity of its software ecosystem. Core is no longer the unchallenged center of gravity—and that might be the best thing for Bitcoin’s long-term resilience.
Final Thoughts
The upcoming Bitcoin update in October 2025 may not create an immediate hard fork, but it represents a fundamental shift in how the network governs itself. As more users migrate to alternative clients like Bitcoin Knots, the lines between policy, consensus, and ideology are becoming blurred.
Whether you view this as progress, peril, or just another chapter in Bitcoin’s evolution, one thing is certain: Bitcoin is once again at a crossroads.
