Bitcoin Audible Roundtable_014 – Soft Forks and Censorship

Date: November 5, 2025
Host: Guy Swann
Guests: Steve Mechanic, Jeff, and others

Episode Overview

This roundtable dives deep into current Bitcoin drama swirling around recent proposed soft forks, censorship concerns, core software changes, and growing disagreements within the Bitcoin community over philosophical and technological directions. The crew discusses the implications of the "filter conversation," breakdowns of BIP 444 (the temporary soft fork proposal), the divide between policy and consensus changes, and wider cultural issues like censorship in Canada.

Community & Censorship Context (04:38–15:35)

• Canadian Censorship Story: Jeff shares how his dentist—outspoken against Covid vaccines—was shut down and repeatedly visited by police.

  • “The censorship here is out of control… more than half the posts on my [FB] feed just say ‘this can’t be shown in this country.’” – Jeff (06:32)

• Bitcoin and Local Cultures: Discussion about the variance of law enforcement and freedoms at the local/provincial/state level, and the impact of living among good people versus just having reasonable laws.

• “Clown World” & Resilience: Participants highlight how censorship and overreach have led to private grassroots Bitcoin communities operating under-the-radar in areas like BC.

• Would you rather…: Classic “bro debate” about living under unenforced crazy laws vs. strictly enforced but reasonable ones, showing how culture often trumps written law.

“Soft Fork” Drama & BIP 444 Deep Dive (15:35–44:55)

• Conference Clashes: Mechanic recounts the intensity of debates at the Lugano Tether Conference, where opposition to “arbitrary data” like inscriptions being stored on Bitcoin seemed widespread among attendees.

  • “The entire room was like, we agree… at an increasing rate, [arbitrary data] is just going to make life harder for nodes for no benefit.” – Mechanic (17:13)

• BIP 444 Origins: A soft fork proposal crafted by “Dathan Ohm” (whose identity is unknown), intended to limit how arbitrary data can be embedded in Bitcoin blocks.

  • Its emergence surprised participants, indicating grassroots demand for stricter controls after policy (relay rules) changes enabled easier data embedment.

• Procedural Friction: Assigning BIP numbers and discussing policy changes has created internal drama, revealing inefficiencies and power dynamics in how Bitcoin development gets done.

• Developer & Miner Blindspots: Major pools (e.g., Antpool) and hardware manufacturers (e.g., Bitmain) seem out of the loop, remaining shockingly uninvolved in nuanced consensus debates.

• Historical Comparisons: Relates current strife to past splits (e.g., the Segwit UASF, BCash) and the role major figures like Luke Dashjr, Greg Maxwell, and Adam Back have played in shaping forks.

• Concerns on Consensus: Guy expresses frustration at both sides “beating their chests,” calling out shallow arguments and lack of nuanced discussion:

  • “You’re literally just jerking off on social... You're not even having the discussion. You’re just saying my part of the discussion is great and everything that disagrees with me is terrible.” – Guy (25:54)

Contiguous vs. Non-Contiguous Data Debate (47:20–59:05)

• Technical Debate: Does storing data all together (contiguous) versus “hidden” in many places (non-contiguous) matter?

  • Some (Carvalho et al.) argue: “broken up data and contiguous data are the same thing.”
  • Others (Mechanic, Guy) strongly disagree: practical file and media formats, interpretability, and user impact matter greatly.
    • “Media players aren’t going to open a .txt or .csv file… If you can do something steganographic, that’s interesting, but… Taproot was not meant for data storage.” – Mechanic (49:01)
    • “My life improved when I realized I could just ignore any sentence that started with ‘technically’… it’s just a way of saying let’s ignore the context.” – Mechanic (58:39)

• Social Layer Trumps Technicalities: Even if technically possible, making spam or arbitrary data storage easier results in real-world bloat, node operator burden, and legal risk.

Miners, Pools, and Soft Fork Dynamics (59:05–66:45)

• Will Big Miners Back the Soft Fork?

  • Some expect mining pools will side with the anti-data crowd, as fees for data are negligible and legal/malware risks are large.
  • “Transaction fees lately… they're less than 1% of block subsidy. If you’re a mining pool, is 1% extra revenue worth all the possible risks?” – Steve (61:49)

• Possible Reactions:

  • Miners might someday produce only empty blocks to avoid risk.
  • Fee market predictions have proven difficult; debates rage about how to ensure long-term security and miner incentives.

What Actually IS the Soft Fork Proposal? (68:41–77:38)

• Technical Details [(68:41)]:

  • Limits scriptPubKey (address output) data to 34 bytes (except OP_RETURN: now 83 bytes).
  • Gets rid of OP_IF entirely, and further restricts various data-storing loopholes.
  • Temporarily: All major routes for storing arbitrary large data are blocked for one year after activation.

• Rationale for Temporary Nature:

  • Avoids a permanent restriction that could only be reverted by hard fork.
  • Allows a cooling-off period to evaluate real world impact and, if negative effects are minimal, to consider a longer or permanent approach.
  • “There’s nothing more permanent than a temporary soft fork.” – Zenda (jokingly quoted by Mechanic, 70:41)

• Risks & Critiques:

  • Chain splits possible if contentious—a chain might fork, then remerge after the year, but this would be messy.
  • Merge mining and replay protection complexities ensue if chains diverge.

Soft Fork Activation, Chain Splits, and Merge Mining (77:38–81:17)

• Merge Mining Variant Concepts:

  • Could a soft-forked chain “accept” blocks from the original chain to ease rejoining later?
  • Would this set a dangerous precedent, opening the door to endless UASF (User Activated Soft Fork) spam/forks?

• Open Process Questions:

  • Soft fork’s technical and social activation mechanisms are still vague; consensus has not been demonstrated.

Sidechains, BitVM, and the Fee Market (81:17–89:08)

• Temporary Soft Fork Will Break Some Features:

  • 444 would make BitVM, advanced sidechain bridges, and large hashed data pushes impossible for a year.
  • “444 kills BitVM for a year… and also kills big OP_RETURN, witness data.” – Steve (79:09)
  • “I’m more interested in Ark than BitVM… the scaling problem is not a problem, we don’t even have transaction demand to make it a problem.” – Jeff (81:29)

• Fee Problem:

  • Reiterated long-term concern: “I'm holding the technicality argument that fees will become a problem, but the real world data [now] doesn't support that hunch.” – Guy (82:12)

Dissent: Is a Soft Fork Even Needed or Wise? (89:08–107:47)

• Guy’s Main Skepticism:

  • Overplaying the hand: UASF only worked when status quo was trying to force a hard fork—here, inertia sides with Core as “reference.”
    • “User activated soft fork worked because the status quo was trying to hard fork… If this soft fork fails, it will just reinforce the reference client.” – Guy (88:48)
  • A better (less risky) tactic might be simply building more user-friendly alternatives (e.g., Bitcoin Knots); if enough users prefer filters, that alone can drive change.

• Soft Fork Risks:

  • “Soft forks are dangerous. They come with a lot of risk, and I have been on the fence as to whether or not this is even a soft-fork-justifiable issue unless there's massive consensus.” – Guy (88:41)
  • “If you already have massive consensus, like 80% running Knots, do you need the soft fork at all?” – Jeff (89:08)

• Alternative: Pursue MemPool Policy, Not Consensus:

  • The line between mempool (relay) rules and consensus rules keeps blurring; some say a soft fork settles the debate, others fear it breaks Bitcoin's modularity.

• Legal Justifications Criticized:

  • “Arguing for this because it's legally less risky is an equally terrible argument... everything about bitcoin is about challenging legal [limits]” – Guy (35:02)
  • All agree BIP 444 should drop legal language; regulatory risk is not the core reason for protocol-wide changes.

Wrap-up: Next Steps and Wider Bitcoin News (107:47–end)

• Next Steps:

  • Wait and see: Participants agree that too much is in flux; will revisit after a month of developments.
    • “Let's everybody dig for the next month and do this again... things are going to be very different.” – Mechanic (91:33)
  • Rising consensus: Focus on nodes, alternative clients, and mining decentralization as higher priorities than protocol hardening right now.

• Broader Bitcoin Developments (Summarized rapidly in closing):

  • [Timestamps ~109:02 onward; see transcript for asides and news details]
  • LightSpark Grid API announced for seamless Bitcoin and fiat settlements.
  • Wallet of Satoshi returns to the US as a “self-custodial” tool.
  • Trezor launches new hardware wallet.
  • South Korea NTS targets cold wallets in tax crackdown.
  • Hashrate explodes, crossing 1 ZetaHash, solo miners find blocks.
  • HRF issues major new grants; Maria Corina Machado wins Nobel for Bitcoin activism.
  • Arcade (ARK) and BullBitcoin release new tools/wallets.
  • Open developer events and wallet innovations (Phoenix, Sparrow, Bisq for Android, Robosats privacy upgrades).
  • Recent Core v30 release discussion: protocol improvements being overshadowed by filter controversy.
  • Calls for more focus—by developers and community—on mining decentralization and stratum v2 support.

Notable Quotes

• On Censorship:
  “The censorship here is out of control … this can’t be shown in this country.” — Jeff (06:32)
• Community Split:
  “The entire room was like, ‘we agree… arbitrary data will make life harder for nodes for no benefit.’” — Mechanic (17:13)
• On ‘Technically’ Arguments:
  “My life improved when I realized I could just ignore any sentence that started with ‘technically’… it’s just a way of saying: let’s ignore the real world.” — Mechanic (58:39)
• On Soft Fork Dangers:
  “Soft forks are dangerous. … if you already have massive consensus, like 80% running Knots, do you need the soft fork at all?” — Guy (88:41); Jeff (89:08)
• On Legal Arguments:
  “[Saying it reduces legal risk is] an equally terrible argument because… everything about Bitcoin is about challenging legal… what is legal in all the places in which it is illegal to do simple things.” – Guy (35:02)

Key Takeaways

• The recent soft fork debate is as much cultural as it is technical, with deep fractures over what Bitcoin is for and how its rules should (or shouldn't) change.
• The “temporary soft fork” (BIP 444) is controversial and may be an overcorrection; the group is divided whether it’s a necessary defense or an unnecessary risk.
• Legal risk is seen as a poor justification for protocol changes; focus should stay on Bitcoin’s monetary neutrality.
• Mining centralization remains a looming threat: seven mining pools can now change behavior for the majority of the network.
• There is a growing appetite for more user-friendly node software, education, and mining decentralization—not just more “forks.”
• The episode ends on an open note: the coming month will likely be pivotal for how this debate plays out.

Suggested Listening/Next Steps

• Tune in for the next roundtable in late November for follow-ups and possible outcomes.
