Caveats: - Sender wallets must support sending to SP addresses - Amounts and tx graph are still publicly visible; UTXOs received to an SP address must be carefully managed with coin control to avoid triggering CIOH* * Payjoin can help confound this but not impossible to untangle

@btc_ireland You can now use a single bitcoin address without destroying your privacy. You can give a silent payment address to anyone, and each transaction they create will go to a unique address within your wallet.

The quantum-mitigation question on every cryptographer's mind: to use hash-based or Lattice-based signatures in Bitcoin? Hash-based signature schemes—e.g. SHRINCs/SHRIMPS by @Blockstream's @n1ckler—have been called "the conservative choice" by @adam3us while @danboneh makes a push for lattice-based signatures. "Hash-based signatures are combinatorial in nature—and that limits a lot of the clever things we can do with them...for example, threshold signatures."

> investment in "quantum-resistant cryptographic upgrades." Y'all ready for .gov BIPs?
TFTC@TFTC21

The American Reserve Modernization Act (ARMA) would authorize the U.S. Treasury to acquire up to 200,000 bitcoin per year for five years, targeting a reserve of 1 million BTC. The bill was introduced Wednesday by Rep. Nick Begich with 16 original cosponsors. It is a rebranding and expansion of the original BITCOIN Act co-introduced last year by Begich and Senator Cynthia Lummis. It would codify Trump's March 2025 executive order establishing a Strategic Bitcoin Reserve into permanent law that cannot be reversed by a future president. The bill classifies bitcoin as a "Tier 1" strategic reserve asset, putting it on the same legal footing as gold. A separate digital asset stockpile would hold other federally owned crypto. All acquisitions must be budget-neutral. The funding mechanism is revaluing Federal Reserve gold certificates from their current statutory price of $42.22 per ounce, set in 1973, to current market prices. That gap generates hundreds of billions in accounting gains without new taxpayer debt. The bill also ends the practice of auctioning off seized bitcoin. All future seizures would be transferred directly to the Strategic Reserve instead of being liquidated by the U.S. Marshals Service. Existing government holdings would be consolidated into a single audited ledger. Bitcoin in the reserve would be held for a minimum of 20 years. The bill establishes federal custody standards including geographic distribution of private keys across air-gapped facilities, multi-signature governance requiring authorization from the Treasury, the Fed, and an independent third agency, and investment in "quantum-resistant cryptographic upgrades." Rep. Pat Harrigan, one of the cosponsors, said "The United States government already holds billions in seized bitcoin with no coherent strategy for managing it, and that needs to change."

Are any developers being prosecuted for "writing code" right now? I agree that BRCA protections are important but we need to be careful not to strawman our opponents. "Code is speech" has been precedent for decades; we won the crypto war.¹ This new war is something else.
Cody Carbone@CodyCarboneDC

Limiting or weakening the BRCA is a non-starter. Prosecuting non-custodial developers will not help law enforcement. It'll waste valuable enforcement resources chasing folks who do not custody customer funds, execute trades, or control user assets. The CLARITY Act must protect developers and preserve the BRCA’s core protections. You do not strengthen America by prosecuting developers for writing code.

@CabanaChemistry @emollick yeah if they did additional training and used this "internal model" only for this problem then there would not be anything else to amortize the training cost against.

@lightcoin @emollick There is a gradient, though. Assuming this problem could not be solved before the current GPT model, then the incremental training cost went disproportionately to this problem compared to, say, telling you the r’s in strawberry

@CabanaChemistry @emollick yes in this context the training cost is effectively amortized across all uses of the model, approaching (but never quite reaching) 0 at the limit

@emollick That would be just the inference, right? Do energy/water costs of training become infinitessimal if divided among all the problems it solves?

Yeah, I think some kind of deterministic anchoring into Bitcoin would help. You could have a UTXO controlled by the supermajority of the federation, which would commit the latest liquid blockheader hash in an OP_RETURN every day or so. That way you have canonical source of truth and no re-orgs are possible after the commitment gets confirmed on Bitcoin. However, you still trust the federation with the data availability, so they can still freeze funds by committing the blockheader on Bitcoin but never actually revealing the blocks.

Liquid with a BitVM bridge would be awesome. Not only does it enable all the Liquid op codes + Simplicity with 1-of-n trust tradeoffs, it would also allow for bootstrapping other exotic L2/protocol designs on top of Liquid without worrying about bridge operation headaches or inheriting honest majority trust tradeoffs. Liquid wishlist: - BitVM bridge - Much faster block times (maybe 5-10s?) - Signed UTXO commitment per block The UX/security tradeoff would be pretty sweet. You could have mobile light clients validate by simply downloading only the most recent block.

The full near-term Liquid development roadmap below. 0-conf, BOLT 12 and LNURL support in @LiquidWalletKit, Simplicity-based Bitcoin DeFi infra, quantum readiness, BitVM-style bridge research, and institutional custody are all in motion. What else would you like to see?

@lightcoin I wonder if that means "principled commitment to non-custodial" or "we don't want to be custodian". ecash would be consistent with the latter, but not the former.

For a network where consensus is based on k-of-n assumption, the BitVM bridge providing 1-of-m (intentionally denoted m, since the operators here might be different from consensus signers/nodes) assumption doesn't improve the security beyond k-of-n, since the consensus majority can re-org the chain after a succesful peg-out through BitVM bridge. Hence you can get same amount of security by just creating a big k-of-n multisig, without the rude-goldberg machine complexities of BitVM. Considering there are 80 federation members, you should be actually able to do a simple OP_CHECKSIGADD multisig for all of them now. Might cost you 2,000vB to peg-out, which is actually not that bad.

Daniel Batten@DSBatten·
I just got back from the Bitcoin Energy Summit in Lisbon and I have a question that won't leave me alone. First some context: Bitcoin mining is now stabilizing the grids of 7 nations, 4 agencies (including the Spanish Govt and the World's largest energy policy association) just called for more flexible demand being critical to the resilience of the grids of the future - and Bitcoin mining is the world's most flexible load resource by an order of magnitude. So in light of this my question is this: why is 95% of the Bitcoin adoption conversation about Bitcoin-as-money when Bitcoin-as-energy is already deployed on grids across 3 continents? Is it possible that energy is the Bitcoin usecase that paves the road for mainstream acceptance of Bitcoin in the West? I've been in this space for four years now. When I started, the conversation was "bitcoin mining wastes energy." A group of Bitcoiners including @thetrocro, @jyn_urso and others changed that. Then it became "ok maybe it doesn't waste energy, but it's not useful." @gladstein, @jack and others changed that too. But here's what I noticed in Lisbon. Three separate European organisations - the European Bitcoin Energy Association, Free Madeira, and the Institut National de Bitcoin in France - are all independently converging on the same conclusion. @geyer_rachel, Chair of EBEA said energy is what will move the needle for Bitcoin in Europe. @andreloja at @FREEMadeiraOrg said energy is the most topical issue in Europe right now. Bastien Desteuque (@Proxy18387764), directeur général at @BitcoinPolicyFr said they're focusing on mining because France has spare nuclear capacity and that's where the biggest opportunity is. Three organisations. Same conclusion. And that's before you get to what's actually being built. In Sweden, a man I coach runs ASIC hardware that earns almost two-thirds of its revenue from frequency regulation - keeping the lights on, responding in seconds to the need of the grid operator, and helping to stabilize the grid an incredible 11,247 times last year alone. (Yes, you read that sentence right). In Lisbon, I watched Kenji Tateiwa present a circular economy where bitcoin mining heat grows tropical fish and the CO2 gets converted to charcoal and micro diamonds. Bastian outlined how France's surplus nuclear energy could be absorbed by bitcoin mining by 2027. And outside the West, from stabilizing the economy of Bhutan post-covid to helping save Virunga National Park in Africa - Bitcoin mining was behind both events and many more. This phenomenon is a global one. The conversation has quietly moved from "does bitcoin mining help grids?" to "how many services can one machine provide?" We've been thinking about this like monoculture - one machine, one function. What I saw in Lisbon is permaculture. The same hardware doing frequency regulation, heat capture, Sats-minting ... and potentially in the near future - voltage regulation (something that would have prevented the 28 April 2025 Iberian Peninsular Blackout). I talked to Bitcoin founders after the keynote who told me the energy thesis had opened their eyes. These are people who worked to advance Bitcoin payment infrastructure, and they hadn't fully grasped this. Bitcoin solves a monetary problem the world is only beginning to understand. I'm more convinced of that than ever. And ... as we wait for that revolution to be fully grasped, the energy revolution is already here - deployed, generating revenue, stabilizing grids. It might just be the thing that opens the door for everything else. What other Bitcoin use case is this far along ... at least in the West?

Stablecoins are the wrong instrument. The companies behind them are chokepoints, as bad as the US government, Swift, Mastercard & Visa Bitcoin is a more viable solution. No one controls it Looking forward to the Africa Bitcoin Conference happening in Malawi in December 2026
Her Majesty, Queen of Code@QUEEN_SheCoder

Malawi has no forex. Every Malawian card fails abroad. The parallel market is illegal but it is the only option. So I asked: what if stablecoins could fix this?
