When spending a Taproot script-path output with SIGHASH_ANYPREVOUT (BIP118), I want to understand what exactly is committed to regarding the script tree. Specifically: if two UTXOs have the same executed leaf (same TapLeaf hash) but different TapTree structures (different Merkle paths), will the same APO signature validate against both? I constructed a multi-round Eltoo chain on Inquisition signet, and observed that the APO signature can still be reused across rounds and successfully spend the output. I also confirmed that the same APO signature can spend two different UTXOs with identical scripts and amounts ( tx1 , tx2 ). This suggests that the signature commits to the TapLeaf hash, but not the full Merkle path — and I’d like to confirm whether this is the correct interpretation. from Recent Questions - Bitcoin Stack Exchange https://ift.tt/8RLqVjy via IFTTT

With OP_CHECKSIGFROMSTACK (CSFS), signatures are verified against an explicit message rather than the transaction sighash. This seems to allow the same (sig, message) pair to be reused across different UTXOs, unless something binds the message to a specific context. Some discussions (e.g. by Jeremy Rubin https://rubin.io/bitcoin/2024/12/02/csfs-ctv-rekey-symmetry/ ) mention re-keying or laddering constructions to mitigate this. My question is: How exactly do CSFS laddering or re-keying schemes prevent cross-UTXO replay in practice? What is the binding mechanism — is it based on chaining commitments, updating keys per step, or something else? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/NYzps2H via IFTTT

I’ve been testing simple opcode combinations — CHECKSIG, CSFS, IK+CSFS....trying to get a feel for what each one actually binds. It feels like the challenge is less about expressiveness, and more about choosing the right kind of binding. I’m wondering: Do developers see this as its own discipline — not Ethereum-style contracts, but something like designing Bitcoin’s contracts within constraints? Does that map to a distinct kind of engineering role over time? Or is this still just considered script work? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/7xwDKoX via IFTTT

I’ve been running opcode composition experiments (e.g. CAT+CSFS, IK+CSFS) on signet. Related: #130613 , #130598 , Delving thread In several cases, the script validates correctly, but still feels structurally unsafe (e.g. replay, cross-UTXO reuse, weak binding). My question: How do experienced developers recognize these issues early, before they turn into real vulnerabilities? In particular, how do you reason about whether a construction is "too general" or insufficiently bound? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/1lGnXZD via IFTTT

Following up on #130598 . I built a CAT + CSFS oracle-style script on signet ( commit , reveal ): OP_CAT OP_SHA256 <oracle_pubkey> OP_CHECKSIGFROMSTACK Witness: [sig, PART1, PART2] Message: SHA256(PART1 || PART2) Since CSFS only checks the message, the same (sig, PART1, PART2) appears to be reusable across multiple UTXOs with compatible scripts. For price oracles this is usually acceptable. But if the goal is single-use authorization (i.e., the signature should only be valid for one specific UTXO): Is committing to the outpoint inside the message the only general approach? Or is there a script-level pattern that avoids requiring the oracle to wait for the UTXO to exist before signing? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/wHOPXSB via IFTTT

I ran a CSFS experiment on Bitcoin Inquisition Signet and got a spend confirmed: https://mempool.space/signet/tx/cc1b6d352f75348b6a52c7f5c68fc5caea2512423e08011e8f69a9bb85195f97 The tapscript is simply: <pubkey> OP_CHECKSIGFROMSTACK The witness provides (sig, msg, script, control_block) . Since (sig, msg) becomes public after spending, if another UTXO is later sent to the same script, anyone could reuse the exact same pair to spend it — because CSFS only enforces: schnorr_verify(pubkey, msg, sig) with no commitment to the spending transaction. By contrast, OP_CHECKSIG signatures commit to the input outpoint, so cross-UTXO reuse is impossible. This leads to three questions: Is cross-UTXO signature reuse an intentional property of CSFS, or a risk that must be handled at the script level? What are the standard patterns to prevent unintended reuse — include the outpoint in msg ? combine with OP_CHECKSIG ? In oracle constructions where reuse is desirable (e.g., attesting...

In a recent discussion about Bitcoin’s architecture (< https://bitcoin.stackexchange.com/questions/130583/is-bitcoin-better-understood-as-a-state-machine-or-a-database/130585?noredirect=1#comment146364_130585> ), Pieter Wuille noted that even the concept of the UTXO set itself postdates Satoshi’s departure, suggesting that some of the mental models we use today emerged later as the system evolved. Looking at the evolution of Bitcoin’s spending mechanisms, many features appear to follow a commit–reveal pattern（ When — and why — did Bitcoin Script shift to a commit–reveal structure? ）. However, many modern cryptographic systems instead follow a different structure: commit → prove → verify I’m curious: Is the current commit–reveal pattern a fundamental property of Bitcoin’s design, or could future extensions push the system toward proof-based validation mechanisms? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/KdJ6ykH via IFTTT

Bitcoin is commonly described as a “decentralized database,” but looking at how a full node actually works, that framing feels a bit off. Blocks form an append-only transaction log. Nodes replay that log to derive the current UTXO set, which Bitcoin Core stores in LevelDB (chainstate/). That’s not really how traditional databases work — it feels closer to event sourcing or a replicated state machine where the ledger state is derived rather than primary. So which mental model is actually correct? • Is the UTXO set the “database “? • Or is the block log canonical, with the UTXO set essentially being a cache that could be reconstructed? Is there anything from early mailing list discussions or Satoshi’s design notes that addresses this directly? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/97PciCx via IFTTT

Re-reading the whitepaper, Section 2 describes ownership as transferring coins directly to the next owner's public key — which maps to P2PK. That's the last standard type where the full spending condition is visible in the output. Every format since then does the reverse: commit to a hash, reveal the preimage at spend time. P2PKH started it — hides the pubkey behind a hash, revealing it only at spend time. P2SH, P2WSH, and eventually Taproot all extend the same logic, with Taproot pushing it furthest by hiding an entire Merkle tree of scripts. Was this a deliberate design direction, or did each upgrade respond to its own pressures independently? Is there a mailing list thread or BIP discussion where this pattern is explicitly articulated? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/DsYl6g1 via IFTTT

The conversation around real-world asset (RWA) tokenization is heating up, and the numbers are staggering. After digital asset securities firm Securitize highlighted the potential for a $400 trillion global asset market to move on-chain, attention quickly shifted to the blockchains positioned to support that scale. The XRP ecosystem, specifically the XRP Ledger, is increasingly being discussed as a possible infrastructure layer for this next phase of financial digitization. How The XRP Ledger Supports Asset Tokenization Crypto commentator Archie is sounding the alarm for the XRP community, pointing to Securitize teasing a massive $400 trillion real-world asset (RWA) opportunity that could reshape global finance and potentially position the XRP Ledger at the center of the shift. According to Archie’s post on X, a recent update from the tokenization giant stated that only about $25 billion in assets have been tokenized, with an estimated $400 trillion in traditional assets.  Thi...

Once an escrow expires, anyone can unlock it. Schwartz also addressed claims that the XRPL Ledger was centralized because Ripple has a “Unique Node List,” which effectively makes the validator...

British gamblers searching for ways to bet with cryptocurrency are more likely to end up on an illegal website than a regulated one. That is part of what prompted the UK Gambling Commission to start asking whether something needs to change.

Bitcoin’s long-term structure has always been examined through the perspective of its halving cycle, and one crypto pundit believes the pattern is pointing to a clear price bottom.  The analysis centers on a recurring time-based rhythm tied to each halving event, and it proposes a specific window for when accumulation could begin again.

Ripple is reshaping how builders on the XRP Ledger get funded in 2026, arguing that the ecosystem has reached a point where support needs to flow through more than Ripple-linked programs alone. The change matters because it signals a deliberate move away from a relatively centralized funding structure toward a broader network of DAOs, independent hubs, universities and venture partners. In its latest ecosystem update , Ripple said more than $550 million has already been deployed into XRPL initiatives since 2017, spanning non-equity grants, builder incentives, strategic partnerships and growth programs.

It has been a brutal few months for Dogecoin in terms of price action. At the time of writing, Dogecoin is trading just below $0.10, below all of its moving averages, and sitting more than 86% below its all-time high.  The price action looks bad for Dogecoin; however, a look at the on-chain data tells an entirely different story of resilience and network activity that’s being ignored. If history is any guide, this is exactly the kind of environment before a major recovery. Dogecoin’s Network Growth Price is often the last thing to move during rallies.

Building software has never been against the law. But in recent years, some crypto and blockchain developers have found themselves facing federal criminal charges simply for creating tools that others used to move cryptocurrency — even when those developers never held a single dollar of anyone’s money. A new bill introduced in the US House of Representatives is aimed squarely at closing that gap. A Bipartisan Push To Protect Developers Representatives Scott Fitzgerald, Ben Cline, and Zoe Lofgren announced Thursday that they are sponsoring the Promoting Innovation in Blockchain Development Act. The legislation targets a specific section of federal law — Section 1960 — which currently prohibits the operation of unlicensed money transmitting businesses. The bill would tighten the definition so that the law applies only to those who actually hold or control other people’s digital assets. Developers who write code, maintain networks, or build platforms without ever touching user funds...

On-chain data shows spot demand for Bitcoin is returning as the Apparent Demand metric has started to grow for the first time since late November. Bitcoin Apparent Demand Has Seen Its 30-Day Sum Turn Green In a new post on X, CryptoQuant head of research Julio Moreno has discussed the latest trend in the Apparent Demand of Bitcoin. This on-chain indicator provides an estimate for the spot demand for the cryptocurrency that’s present on the network right now. It does so by comparing two metrics: the mining issuance and change in the 1-year inactive supply. The mining issuance is the amount of the asset that miners are ‘minting’ on the blockchain every day through their mining activities. It can be considered as a measure of the asset’s total production. In contrast, the 1-year inactive supply, corresponding to coins dormant since more than one year ago, represents the cryptocurrency’s inventory. When the value of the Apparent Demand is positive, it means the decrease in the inven...

Michael Saylor used his Strategy World 2026 keynote on Feb. 25 to argue that Bitcoin-backed “digital credit” is moving beyond Wall Street wrappers and toward programmable distribution on crypto rails, naming Solana and Ethereum as part of that future. The pitch matters because it pushes Strategy’s Bitcoin treasury model into a broader product thesis: use Bitcoin as the capital base, then package credit, yield and liquidity for corporates, retail investors and eventually tokenized markets. Bitcoin Capital, Credit Product Saylor framed Bitcoin as the foundation of the stack and Strategy’s Stretch (STRC) as the credit layer built on top of it. In his telling, the company’s business is no longer just accumulating Bitcoin, but “converting capital into credit” by using long-duration capital structures to strip cash flow from a volatile asset and deliver it as a steadier yield product. “What is Strategy doing? Our company is converting capital into credit. We’re converting economic wealt...

Following a brief and sudden market-wide uptick, the Ethereum price is drawing closer to the pivotal $2,100 mark again, recording a 12% rise in the past day. Despite the bounce on Wednesday, the broader market of ETH is still quite bearish, but bullish sentiment appears to be gaining momentum in the Spot ETFs sector. Sharp Decline Meets Quiet Ethereum Spot ETF Inflows The recent price movement of Ethereum has been quite harsh, with steep declines and ongoing volatility significantly impacting market sentiment. However, beyond the persistent waning price action, a different narrative is unfolding in the Ethereum Spot Exchange-Traded Funds (ETFs) . Despite the sell-off, causing ETH’s price to drop from $4,900 to under $2,000, spot ETF flows show renewed interest and, in certain situations, ongoing capital allocation. This discrepancy between robust ETF demand and poor price performance raises the possibility that institutional and long-term investors are seeing the decline as an oppo...

The founder of Capriole Investments has highlighted how Bitcoin is currently facing the most net selling pressure from institutions in history. Bitcoin Is Observing An Exit From Institutional Entities In a new post on X, Capriole Investments founder Charles Edwards has discussed the latest trend in the behavior of institutional entities on the Bitcoin network. To gauge institutional activity, Edwards has used the spot exchange-traded funds (ETFs) and treasury companies as a proxy. Spot ETFs are investment vehicles that trade in traditional markets and allow for indirect exposure to BTC. Similarly, treasury companies hold BTC on their balance sheet, making their stock price tied to the cryptocurrency’s movements. Traditional institutional entities are typically wary of blockchain infrastructure, so they tend to take one of the regulated, indirect routes into the asset. Now, here is the chart shared by the analyst that shows how the monthly rate-of-change (ROC) in the combined ETF...
