A cryptocurrency expert and staunch Bitcoin (BTC) supporter, Knut Svanholm, has expressed strong disapproval of the latest Bitcoin Core v30.0 update. This version increases the OP_RETURN limit to 100,000 bytes for multiple outputs per transaction. Svanholm believes this change will encourage activities like crowdfunding and staking on Bitcoin’s primary layer, potentially raising costs for direct transactions.
Bitcoin enthusiasts caution against straying from its fundamental purpose
The introduction of Bitcoin Core v3.0 brings several technical modifications, such as removing the previous 80-byte restriction and lowering relay fees. These updates aim to simplify data storage, facilitate metaprotocol development, and support more intricate applications.
Such advancements are typically associated with other platforms like Ethereum. While some developers see these changes as technical progressions, purists like Svanholm perceive them as threats to Bitcoin’s core ideology.
Svanholm specifically mentioned developers such as Electron Arc-20 who are welcoming these updates. He argued that these features mimic altcoin — or “shitcoin” — characteristics that do not align with native Bitcoin functions.
The implications are clear.
The adjustments in Core v30 pave the way for “new forms of crowdfunding, staking, and digital economies on Bitcoin L1.”
This is undeniably shitcoining and detrimental to Bitcoin’s essence. Any application not focused on facilitating… https://t.co/JDITyS5AT6

Svanholm argues that utilizing Bitcoin for speculative or non-essential purposes undermines its primary mission: facilitating private, low-cost transactions in sats. He asserts that other uses such as DeFi, staking, crowdfunding, and NFTs only clutter the network while increasing transaction expenses.
He urged community members to oppose the adoption of Bitcoin Core v30 by switching to alternatives like Bitcoin Knots which do not incorporate these controversial changes;.
Sustaining a pure Blockchain ecosystem is crucial according to him;.”The opportunists have exhausted their pool of naive targets… now they seek new victims within the realm of BTC,” he remarked;.
Diverging opinions among developers spark intense debate over Core v30
Knut Svanholm isn’t alone in his views;.
Recently,, Luke Dashjr ,a notable developer known for his work on BTC Knots also opposed this direction stating running /v30 equates supporting child sexual abuse materials,a statement prompting reflection about whether unity can ever be achieved ideologically within this community.
 However,a proponent named Jimmy Song disagrees suggesting software usage doesn’t pose existential risks but acknowledges bad actors may exploit certain features without jeopardizing BTC entirely.
 As discussions continue,a recent event left many astonished when five consecutive blocks were mined within twenty minutes—a four-minute average time causing widespread intrigue throughout blockchain circles.
