Major Changes in Bitcoin v30.0
- Lower Fees: Nodes can now relay transactions with fees as low as 0.1 sat/vB, while miners can include transactions at a minimum of 0.001 sat/vB, a notable shift for those following Bitcoin Core v30 mining efficiency updates.
- OP_RETURN Upgrade: One of the most talked-about changes is the OP_RETURN data expansion from 83 bytes to 100KB. Multiple outputs per transaction are now allowed, opening new possibilities for digital asset certificates and metadata embedding, a change that some see as innovative, others label as controversial Bitcoin Core policy creep.
- Wallet & Command Updates: Legacy BDB wallets are now deprecated. All users must migrate to descriptor wallets, with commands like
importwalletanddumpwalletremoved. Developers have noted in Bitcoin Core GitHub issue threads that this modernization significantly improves backup reliability. - New Transaction Types: TRUC transactions aim to lower confirmation conflicts. A simplified

Bitcoin Core Controversial OP_RETURN
The OP_RETURN upgrade has triggered heated debate across the crypto community forums. Critics from the Bitcoin Knots community, including Luke Dashjr, argue that expanding data limits could expose node operators to unwanted on-chain storage risks, including illegal data injection, a legal grey zone often resurfacing during crypto policy crashes and regulatory reviews.
Bitcoin Core developers clarified that the change affects mempool policy only, not consensus, and users can still manually cap data limits. However, some warn that future releases could tighten defaults again, reigniting debate.
Fork and Governance Concerns
In late September, leaked chat logs hinted that Luke Dashjr might consider a counter-fork to resist the current OP_RETURN direction. He later denied any planned Bitcoin Core v30 fork, but reaffirmed his opposition to the change.
This moment mirrors past Bitcoin crash governance tensions, where protocol direction sparked community splits, further fueling discussions about long-term alignment and control.
What’s Next?
Bitcoin Core v30.0 introduces powerful tools and policy flexibility, but the OP_RETURN controversy highlights the ongoing balance between innovation, censorship resistance, and legal risk. Node operators and miners are advised to review config defaults, especially those following Bitcoin Core GitHub updates closely, and adjust according to their jurisdiction and risk profile.
The update serves as a reminder: in Bitcoin, progress often comes packaged with debate and sometimes, ideological volatility rivals price volatility. For traders and builders alike, one thing remains true: Price volatility fades, protocol upgrades stay.

Bitcoin Core (the software) does not have a token, it powers the Bitcoin network. To check CORE/BTC live pricing, traders typically monitor exchange spot pairs.
Is Bitcoin Core still active?
Yes. Bitcoin Core remains the most widely used full-node client on the Bitcoin network. With v30.0 shipping new wallet, mining, and OP_RETURN policy changes, developer activity remains strong, and GitHub commits show continuous refinement, proving the protocol is still under active stewardship.
Is Bitcoin Core wallet good for regular users?
Bitcoin Core wallet is secure but more suited for advanced users, node runners, and those who want full blockchain validation. It offers maximum sovereignty but requires significant disk space and syncing time. For everyday trading, most users prefer lightweight wallets or exchange wallets, while Bitcoin Core wallet is preferred by purists and long-term holders.
Where can I follow Bitcoin Core news?
