Bull Bitcoin just landed in Argentina!

> The creation of the Central Bank of Argentina (BCRA) in 1935 was the worst thing that ever happened to this country. From being one of the most prosperous nations on earth, it became a third world country that destroyed five currencies in just over 50 years.
>
> Hyperinflation, constant devaluation, confiscation, price controls, socialism, economic crises, rising crime, and political corruption are some of the negative effects caused by currency counterfeiting at the hands of the BCRA. Not to mention the millions of Argentines who had to emigrate from their homeland in search of better opportunities.

Where Did All the Fees Go? Analyzing Bitcoin’s Onchain Activity and UTXO Set

> # Introduction 
>
> With the emergence of digital asset treasury companies and bitcoin’s price breaking all-time highs, people have been quick to forget the core value proposition of the Bitcoin network: a decentralized, censorship-resistant monetary system designed to provide permissionless access to global value transfer.  
>
> Since the late-2024 decline in non-monetary Runes and Ordinals activity, Bitcoin’s onchain usage has sharply diminished. We’re now seeing an increasing number of blocks that are “free” or nearly free, meaning the average fee paid is 1 satoshi (one hundred-millionth of a bitcoin) or less per virtual byte. (A virtual byte is the standard unit for measuring transaction size on Bitcoin.) This is a short-term benefit for users who want cheap, fast transfers. However, it adds strain to the economics of mining, which is already under pressure following the 2024 halving.  
>
> This note analyzes the structure of Bitcoin’s fee market to assess what’s really happening onchain and examine what it means for the network’s economic health. It also analyzes OP_RETURN transactions and their evolving usage. This is particularly relevant given the debate surrounding Bitcoin Core’s upcoming v30 release. This version of the network's open-source software would allow much larger and multiple OP_RETURN outputs per transaction by default. The planned changes have sparked criticism from parts of the Bitcoin community concerned about spam.  
>
> # Key Takeaways 
>
> - Bitcoin fee pressure has collapsed. 
>   - Median daily fee has dropped >80% since April 2024. 
>   - As of August 2025, ~15% of daily blocks are “free blocks.” 
> - OP_RETURN activity surged and receded. 
>   - During peak Runes adoption (Q2-Q3 2024), OP_RETURN txs often accounted for 40-60% of daily txs. 
>   - As of August 2025, that share has declined to ~20%. 
> - Mempool activity is lacking.
>   - The percent of not-full blocks has spiked to nearly 50% at times in the past few months.
>   - A dormant mempool could pose long-term sustainability questions for miner revenue following the 2024 halving, which reduced block rewards to 3.125 BTC. 
> - Onchain activity may be getting displaced by alternatives. 
>   - Spot BTC ETFs now hold ~1.3 million BTC, much of which doesn’t really move onchain. 
>   - Trading and speculative activity are shifting to alternative L1s like Solana, especially for use cases such as memecoins and NFTs.
> - Over 1.5 million BTC are still held in legacy P2PK addresses. These are bare public key addresses and are considered immediately vulnerable to potential quantum computer attacks because the public key is exposed onchain at all times. 
> - Over 6 million BTC are still held in legacy P2PKH addresses. 
> - P2WPKH now holds the largest share of unspent BTC out of any address format.

Eclipsing Bitcoin Nodes with BGP Interception Attacks

> *by cedarctic*
>
> # Summary
>
> This post contains a collection of my findings on an attacker being able to eclipse Bitcoin nodes using interception attacks - a stealthier variant of the standard BGP hijack.
>
> Key takeaways: The attack seems to be feasible against many nodes in the network, and I was able to produce a proof-of-concept by attacking my own mainnet node in an isolated environment. To hinder this type of attack, I looked into several mitigations, some of which use networking data that the node can observe independently.
>
> The rest of the post presents the attack in detail, looks into its feasibility, presents findings from a proof-of-concept implementation, discusses networking data that can be used in defenses, and concludes with a description of the proposed mitigations.

Bitcoin: A moral imperative

> **What Bitcoin is for me and why it should matter for everyone**
>
> ![](https://m.stacker.news/106681)
>
> For many, including myself, the creation and printing of money represents a profound ethical problem that is becoming really unacceptable. This perspective posits that entities which monopolize, print, and allocate capital on behalf of others commit actually a moral violation. Such actions are seen to deplete the opportunities, time, and energy of future generations, leading to a level of indebtedness that is now impossible to overcome for western people. These behaviors concentrate power in the hands of a few persons, who are often corrupt, and encourage wars and oppression of people all over the world. In this article I am taking in consideration the ideas from Gigi and Jack Mallers who were extremely inspirational for me all along my path to Bitcoin.

CVE-2024-38365 public disclosure (btcd `FindAndDelete` bug)

> *by AntoineP*
>
> This work is a collaboration between Niklas Gögge (Brink) and Antoine Poinsot (Wizardsardine).
>
> Btcd prior to version 0.24.2 does not correctly implement the consensus rules for legacy signature verification. The incompatible behavior can be triggered by a standard transaction, making it possible for anyone to fork off vulnerable btcd nodes at virtually no cost.

United States of Bitcoin

> ![](https://m.stacker.news/106834)
>
> States begin as stories. Before there are buildings, flags, or budgets, there is a shared narrative about who we hope to be, what we should expect from one another, and which rules merit our consent. The American story was spoken into being before it was built with Thomas Paine instilling “we have it in our power to begin the world over again,” a sonnet at the harbor promising a fresh start to the tired and poor, a public debate informing citizens factions would always arise and to control their effects and to bind power with words where ambition checks ambition. America’s pattern of inception is repeatable: people tell a story, that story hardens with consent into a written charter, constitution, and only then do the visible structures coalesce into institutions, law, and civic culture.
