The Frontier

Morgan Stanley’s spot Bitcoin ETF (MSBT) began trading with a 0.14% expense ratio, undercutting BlackRock's iShares Bitcoin Trust (IBIT) at 0.25%.

Nate Geraci notes Morgan Stanley's competitive edge comes from its army of wealth managers and trillions in client assets, not just its low fee. James Seyffart argues IBIT's liquidity dominance will be hard to replicate.

Iran is exploring collecting cryptocurrency, potentially Bitcoin, as a $1-per-barrel transit fee for oil tankers using the Strait of Hormuz during a two-week ceasefire.

A White House Council of Economic Advisors analysis found banning stablecoin rewards would boost community bank lending by only 0.026%, contradicting banking lobby warnings of catastrophic deposit losses.

David Bennett views the Mythos reveal as a marketing campaign similar to the 'New Coke' strategy, designed to generate hype by touting an exclusive, powerful product.

A New York Times investigation suggests Adam Back may be Satoshi Nakamoto, citing similarities in writing patterns from cypherpunk mailing list archives. Back has consistently denied the claim.

OpenSats announced its sixteenth wave of grants, funding projects like Nostr Mail, a decentralized email system built on the Nostr protocol.

Actress Mila Jovovich, in collaboration with Bitcoin coder Ben Sigman, developed an open-source AI memory tool called Mem Palace, inspired by ancient mnemonic techniques.

An academic paper concludes a quantum attack on Bitcoin mining using Grover's algorithm would require energy roughly equal to 3% of the sun's output, making it physically unfeasible.

David Bennett characterizes the simultaneous release of quantum FUD, Mythos AI warnings, and the NYT Satoshi story as a coordinated fear campaign to suppress Bitcoin's price.

Nemeth recommends individuals use AI tools to fact-check his claims, share information on social media to build pressure, and personally hedge with cash and Bitcoin without rooting for systemic collapse.

Host Marty Bent connects the insurance crisis to Bitcoin's value proposition. He argues Bitcoin offers a way to route around a corrupt financial system, especially for younger generations radicalized by repeated financial crises.

Pavel first used Bitcoin in 2015 at Paral Polis, a Prague café that only accepted Bitcoin, which framed the technology for him as a tool for freedom, not investment.

Pavel began contributing to Samurai's Dojo software in 2019 because it was written in JavaScript, a language he knew, allowing him to add features to the open-source node software.

Ronin Dojo remains active despite setbacks, with Pavel finishing a UI update that will reintegrate a transaction privacy analysis tool, similar to the defunct kycp.org site.

The Samurai team's arrest was a sudden escalation, moving directly to prosecution without prior cease-and-desist orders or app store removals.

Pavel says a key lesson from the Samurai case is to not publicly announce plans, as the team's open discussion of decentralizing Whirlpool likely triggered the swift FBI action.

Pavel believes the Bitcoin privacy movement lacks clear direction post-Samurai, with many users moving to Monero or giving up, though projects like Ashigaru continue the work.

Ashigaru is a fork of Samurai Wallet that demonstrates open-source code cannot be stopped by arrests; its team recently relaunched Whirlpool as an act of defiance.

Pavel notes Ashigaru's team communicates only via email, making public trust reliant on their transparency in documenting code changes and their rationale.

A recent Dojo update includes Soroban, a peer-to-peer network that routes transactions through random nodes to obfuscate their origin before broadcasting to Bitcoin.

Pavel recommends following Frank Corva, Econo Alchemist, and Max Tannehill for accurate information on the Samurai case and Bitcoin privacy.

Support for the arrested Samurai developers can be directed to ptprights.org, which accepts Bitcoin and fiat donations for their legal defense.

Justin says Fedimint's eCash app is positioned as a reference client and now includes a Nostr-based contact system, allowing users to input any Nostr public key to populate payment contacts without logging in.

The eCash app uses Nostr for a non-custodial recovery mechanism. It encrypts and stores federation invite codes on relays, derivable solely from the user's seed phrase.

Fedimint is a chaumian eCash system using a federation of guardians. It employs a multisig where, in a typical four-guardian deployment, three signatures are required to move funds.

Justin argues the primary operational risk for eCash systems like Fedimint is unintentional uptime failure, not malicious rug pulls, because running high-availability services is difficult for average operators.

Fedimint now offers Start9 and Umbrel packages for easy guardian deployment. The setup involves a ceremony where guardians exchange codes, now facilitated by QR codes for in-person setup.

The project uses Iroh for peer-to-peer networking, removing the previous DNS requirement. Clients and guardians communicate directly via Iroh, which supports hole punching and relayed modes.

Justin states running a guardian can expose your IP to users and your ISP. He recommends using a VPN like Mullvad for privacy, as integrated Tor support is still in development.

Fedimint's Lightning Gateway is a separate entity that facilitates payments. Users trust it for uptime and liquidity, not custody, as funds remain secured by the federation's multisig.

A gateway can serve multiple federations, enabling capital efficiency. If a payment occurs between two users on federations served by the same gateway, it becomes an internal ledger transfer, not a Lightning payment.

Justin's team released an Android app that can run a Fedimint guardian, drastically lowering the barrier to entry. It runs as a foreground service, is data/power intensive, and allows setup via QR codes.

The Android guardian app can use Explora (Mempool.space) by default for blockchain data but can also be configured to connect to a local Bitcoin Core node.

Justin sees eCash as well-suited for AI agents because it outsources Lightning complexity. Using a personal mint for an agent provides a potential 'undo button' if the agent loses its wallet database.

Odell notes a community in South Africa is using Fedimint as a daily driver for expenses, indicating early adoption for local community banking use cases.

Justin says upcoming work includes making the gateway more agent-friendly, adding new consensus modules, and implementing Bolt 12, though Bolt 12 presents a trust model challenge similar to LNURL.

Jonas Nick details Shrimps, a post-quantum hash-based signature scheme where signatures are 350 bytes on a primary stateful device. If that device is lost, imported devices produce 2.5 kilobyte signatures, with a final 8 kilobyte fallback for catastrophic failure.

Shrimps and its predecessor Shrinks require wallets to be stateful, tracking an incrementing integer for each public key to count signatures. If this state is lost or corrupted, security breaks and the wallet must use a large fallback signature.

Conduition highlights isogeny-based cryptography as a promising post-quantum candidate because its structure allows key re-randomization. This enables BIP32-like hierarchical key derivation and Taproot-like key tweaking, features hash-based and lattice-based schemes struggle to replicate.

SkiSign, an isogeny-based signature scheme, has 65-byte public keys and 148-byte signatures. Verification is about 50 times slower than Schnorr or Dilithium, posing a potential bottleneck for full block validation.

Conduition notes isogeny cryptography relies on the supersingular isogeny path problem, a newer but well-studied assumption. He cautions that schemes like SkiSign and PRISM have complementary security proofs, making it hard to prove both secure simultaneously.

Armin describes how wallet fingerprints - artifacts like signature grinding, SIGHASH flags, and nSequence values - can break PayJoin privacy. Analysts can partition transaction inputs between sender and receiver by spotting inconsistent behaviors between collaborating wallets.

Explicitly stating SIGHASH_ALL in Taproot signatures is a wasteful bug that creates a fingerprint. Since Taproot defaults to SIGHASH_ALL, including the byte adds unnecessary transaction weight and identifies non-compliant wallets.

BIPs 440 and 441, part of the "script restoration" effort, are now published. BIP 440 proposes a VAR Ops budget for limiting script complexity, while BIP 441 proposes re-enabling disabled opcodes like OP_CAT within a new Tapscript version.

Pais proposes BIP 2130, a standard for wallet backup metadata formats. It aims to create an interoperable way to export and import not just descriptors, but full wallet state including labels, transaction history, and coin data.

Eclair 3269 adds automatic liquidity reclamation, closing idle redundant channels. It reduces relay fees over time and closes a channel if, after five days at minimum fee, payment volume stays below 5% of capacity and the local balance is over 25%.

LDK adds support for zero-channel-reserve channels, primarily for LSP-user relationships. This lets users commit their full on-chain balance to a channel, shifting the trust and risk onto the service provider.

LND implements proper MuSig2 nonce handling and RBF support for cooperatively closing simple Taproot channels. The update hardens the protocol against nonce reuse, which could expose private keys.

Jeff Booth argues every individual constructs a personal reality that reinforces their own belief system, making an objective measure like Bitcoin essential for grounding.

Booth posits the natural state of a free market is deflation, driven by entrepreneurs competing to create more value for consumers.

He asserts exponential technology growth, specifically in AI, should lead to exponential deflation and abundance, a trend incompatible with inflationary debt-based money systems.

Booth forecasts a chaotic period of supply chain shortages and rampant inflation, followed by massive monetary printing to prevent a deflationary collapse that would destroy the current money system.

He differentiates between viewing Bitcoin as a static asset for digital credit and as an emergent monetary protocol, arguing the latter is necessary for it to succeed as a free market tool.

Booth contends that digital credit built on top of Bitcoin centralizes control and is binary: it will either be wiped out by the deflationary free market or destroy Bitcoin's potential.

He states that agency in the modern system is lost by using fiat money, which can be printed unilaterally, and is regained by participating in the Bitcoin ecosystem.

Booth observes a high concentration of INTJ/ENTJ personality types among Bitcoiners, attributing it to their ability to grasp and build upon its abstract, emergent protocol nature.

He argues that in a true Bitcoin standard, credit would diminish as a percentage of the economy, replaced by equity investment, as lending 'out of thin air' would fail.

Polymarket is rolling out a completely rebuilt trading system and a new native stablecoin called Polymarket USD, which is backed one-to-one by USDC rather than directly by dollars.

The SEC's crypto safe harbor proposal, which would allow projects to launch without immediate registration, is now at the White House's OIRA for review before publication.
