RETURN Limit Removal in Next Release
The OP_RETURN limit is an 80-byte cap on the amount of arbitrary data that can be embedded in a Bitcoin transaction using a special, unspendable output field.
'Large-data inscriptions are happening regardless and can be done in more or less abusive ways,' said Core contributor and Engineer at Blockstream Greg Sanders, known as 'instagibbs,' in a post on Github announcing the removal. 'The cap merely channels them into more opaque forms that cause damage to the network.'
The debate centered on whether lifting the 80-byte OP_RETURN limit promotes transparency and simplifies data use on Bitcoin, or whether it opens the door to abuse, spam, and a shift away from Bitcoin's financial focus.
On Github, Sanders added that enforcing the cap has created perverse incentives pushing users to embed data in fake public keys or spendable scripts. Removing the limit, he argues, 'yields at least two tangible benefits: a cleaner UTXO set and more consistent default behavior.'
Not everyone is convinced. Core developer Luke Dashjr has long viewed inscriptions and other data storage as spam, and warned in April 2025 that this change was 'utter insanity.'
Amid the controversy, Bitcoin Knots, also maintained by Dashjr, has seen growing adoption, hitting approximately 5% share of all nodes.

Bitcoin Knots, a more customizable fork of Bitcoin Core, appeals to users seeking greater control over what their nodes relay or store, including allowing users to reject non-payment transactions like inscriptions.
Some prominent thought leaders in the industry, like Samson Mow, are encouraging node operators not to upgrade their version of Bitcoin Core, or use Knots instead.
Sanders defended the removal of the cap as aligned with Bitcoin's ethos: minimal, transparent rules.
'By retiring a deterrent that no longer deters,' he wrote, 'Bitcoin Core lets the fee market arbitrate competing demands.'
But that isn't bringing much consensus.
'This marks a fundamental shift in the direction of Bitcoin,' one commenter warned on GitHub.
"This is the largest mistake Core can make at this juncture," another on Github added. 'I want to be on the record saying that.'
CORRECT: (May 6, 08:14 UTC): Removes "former" developer from seventh paragraph.

BTC Miner Cloud Mining Platform Uses Green Energy & High Security, Allowing Users to Invest Safely
Corona, CA August 04, 2025 --( )-- As the price of Bitcoin fell slightly from the high point in mid-July, the market entered a short-term adjustment phase. Despite the large fluctuations of Bitcoin, mainstream analysis agencies generally believe that this round of adjustments is a 'benign reshuffle' on the way up. According to reports from many financial media, institutions are continuing to adjust their positions, and some institutions even show signs of increasing their positions during the correction, releasing long-term bullish signals. Short-term fluctuations are frequent, and ordinary investors prefer 'stability and profit.' For ordinary investors, frequent market fluctuations and complex trading strategies constitute the threshold for participation. In this context, 'cloud mining' is a passive income model that does not require operation, daily settlement, and hedges against market fluctuations. BTC Miner, a compliant cloud mining platform registered and regulated in the UK, states that it is attracting more and more conservative and long-term investors with its stable daily income, green energy drive and high security.

Although it is currently in a short-term adjustment period, industry experts are still optimistic that Bitcoin will break new highs this year. BTC Miner says that in the past week, even in the face of falling Bitcoin prices, BTC Miner Users still receive a fixed income every day without manual intervention or market speculation.

Bitcoin Mining With Nuclear Energy? French Lawmakers Are Considering It
France's far-right political bloc is pushing an ambitious plan to mine Bitcoin (CRYPTO: BTC) using excess energy generated by the country's nuclear power plants. What Happened: The initiative, led by Rassemblement National (RN) lawmakers, marks a striking turn from the party's prior hostility toward cryptocurrencies, and signals a broader ideological shift within European digital asset politics, according to a local news report published on July 30. During a March visit to the Flamanville nuclear facility, party leader Marine Le Pen endorsed the idea of using surplus electricity to power Bitcoin mining operations. The plan would place high-performance computing rigs directly at nuclear sites, converting idle energy into freshly minted Bitcoin, now valued at over €100,000 each. "This is a secure and highly profitable solution," said RN lawmaker Aurélien Lopez-Liguori, who is currently drafting legislation to bring the concept to parliament. He contrasted the proposal with environmentalist positions, stating, "For the Greens, the best energy is what isn't produced. For us, it's energy that isn't wasted." Also Read: Why It Matters: While this marks RN's most concrete proposal on crypto to date, the party's stance on digital currencies has shifted dramatically over the years, from calls to ban them in 2016 to active promotion in 2025. Despite growing enthusiasm among RN members, internal skepticism persists. Senior party official Jean-Philippe Tanguy expressed concern about relinquishing state control over money, warning against "currency independence"—a direct challenge to Bitcoin's original anti-centralization ethos. The RN's sudden embrace of Bitcoin isn't isolated. Other far-right figures, including Sarah Knafo of the Reconquête! party and conservative politician Eric Ciotti, have also championed Bitcoin, with some even calling for France to build national reserves in the digital currency. They cite leaders like Donald Trump and Nayib Bukele as models for blending nationalism with pro-crypto policies. This alignment has deepened ties between right-wing politicians and French crypto entrepreneurs. Some founders, including Ledger's Eric Larchevêque and Paymium's Pierre Noizat, have publicly appeared at far-right events, especially following security threats involving their families. Their comments have increasingly echoed nationalist rhetoric, criticizing the French welfare state and immigration policies while advocating for a "libertarian revival" in Europe. Meanwhile, crypto industry groups lament the politicization of digital assets in France, which they say has been exacerbated by left-wing disengagement. As mainstream parties remain cautious, often citing environmental risks or criminal misuse, industry voices warn that leaving the debate to the far right risks skewing the public narrative.
