Bitcoin Fork Incoming? Core vs Knots and the Battle for BTC’s Future
🎯 Summary
Podcast Episode Summary: Bitcoin Fork Incoming? Core vs Knots and the Battle for BTC’s Future
This 23-minute podcast episode explores the current tensions within the Bitcoin community, focusing on a controversial proposal regarding the OP_RETURN function, the philosophical divide between Bitcoin Core and Bitcoin Knots implementations, and the looming, existential threat of quantum computing. The host, Guy, assesses the likelihood of a hard fork resulting from these issues.
1. Focus Area
The discussion centers on Bitcoin protocol governance, technical policy changes, and long-term security risks. Key themes include the debate over on-chain data storage (Ordinals/Inscriptions), the historical context of Bitcoin block size wars, and the potential impact of quantum computing on cryptographic security.
2. Key Technical Insights
- OP_RETURN Policy Change: Bitcoin Core developers plan to remove the 80-byte limit on the
OP_RETURNfunction (used for attaching small, unspendable data to transactions). They opted for complete removal (Option C) over raising the cap (Option B) to align default policy with existing network workarounds and simplify relay paths, arguing the existing cap is ineffective. - Standardness vs. Consensus Rules: The removal of the
OP_RETURNcap is a standardness rule adjustment, governing transaction relay, not a consensus rule, which defines block validity. This means the change does not technically require network-wide consensus to be implemented by Core nodes, fueling community friction. - Quantum Threat Mechanics: Quantum computers threaten Bitcoin via their ability to exponentially increase computational power using qubits (which can be 1 and 0 simultaneously). Cracking Bitcoin’s SHA256 encryption is theoretically possible with around 8,000 logical qubits, a threshold that is not yet met but is considered an eventual inevitability.
3. Market/Investment Angle
- Fork Likelihood & Impact: The current OP_RETURN dispute between Core and Knots is deemed unlikely to cause a hard fork because the disagreement is policy-based, and both clients will still validate the same chain. A resulting fork would likely be a “flop.”
- Quantum Risk to Supply: Approximately 3.8 million BTC are potentially vulnerable to theft by future quantum computers because they reside in legacy wallets whose keys cannot be easily upgraded to post-quantum cryptography. This potential dump could severely crash BTC’s price and confidence.
- Cost Efficiency of Data Storage: Workarounds for storing data larger than 80 bytes (like Marathon’s controversial Slipstream service) are reportedly four times cheaper than using the
OP_RETURNfunction, suggesting that even if the cap is removed, high-volume data spam is financially disincentivized.
4. Notable Companies/People
- Bitcoin Core Developers: The primary group pushing for the removal of the
OP_RETURNlimit, arguing for modernization and discouraging harmful workarounds. - Bitcoin Knots (Luke Dashjr): An alternative node implementation maintained independently, which opposes the
OP_RETURNchange, viewing it as inviting spam and deviating from Bitcoin’s monetary purpose. - Casey Rodarmor: Creator of the Ordinals and Inscriptions protocols, whose innovations spurred the current debate over on-chain data usage.
- Satoshi Nakamoto: Mentioned historically regarding the initial 1MB block size limit and his early alignment with “small blockers.”
5. Regulatory/Policy Discussion
The discussion highlights the inherent governance challenge in decentralized systems: how to implement necessary technical upgrades (like quantum resistance) without consensus. The potential solution—a hard fork mandating migration to quantum-proof wallets—raises profound policy questions about immutability vs. security, potentially requiring the community to choose between destroying core principles (e.g., reclaiming lost BTC) or accepting catastrophic loss.
6. Future Implications
The conversation suggests two diverging paths:
- Short-Term Stability: The immediate governance conflict (Core vs. Knots) will likely resolve peacefully, reinforcing the dominance of Bitcoin Core policy despite ideological opposition.
- Long-Term Existential Threat: The industry faces an inevitable choice regarding quantum computing: either accept the theft of millions of BTC or implement a hard fork that fundamentally alters Bitcoin’s core ethos of self-sovereignty and immutability. The host leans toward accepting the theft as the “lesser of two evils.”
7. Target Audience
This episode is most valuable for experienced cryptocurrency investors, Bitcoin maximalists, blockchain developers, and industry analysts interested in protocol governance, security implications, and the long-term philosophical direction of the Bitcoin network.

💬 Key Insights
"If quantum computing evolves too quickly, the Bitcoin community could be forced to make an impossible decision: allow this BTC to be stolen and watch its price collapse, or destroy the very core principles of Bitcoin itself."
"If that ever happened, Bitcoin would be no better than a fiat currency."
"The catch is that millions of BTC have been lost or rendered otherwise inaccessible, around 3.8 million BTC to be exact. As such, even if Bitcoin's encryption was increased, the BTC lost on old hard drives and wallets couldn't be made quantum resistant."
"For perspective, a quantum computer would require 4,000 logical qubits to crack the RSA 2048 encryption used on the internet, and would require 8,000 logical qubits to crack Bitcoin's SHA256 encryption."
"However, while this civil war will probably end up being a nothingburger, there is a much larger threat to Bitcoin that we need to be aware of, and that is quantum computing."
"Central to these philosophical differences is whether Bitcoin should only be used as a form of money, or if it could also support other use cases, such as Ordinals, Inscriptions, or Runes, for example."
