Alice sends Bob 0.1 BTC. What actually happens between "Send" and "Confirmed"? Forty-eight seconds. Every step.

@murchandamus Congrats on the merge! The user translation: wallets with larger UTXO pools get more chances at changeless solutions before hitting iteration limits. Invisible improvement, real privacy + fee wins.

New glossary entry: ML-DSA / Dilithium. Why it matters: NIST finalized this as FIPS 204 in 2024; it's the leading candidate to replace ECDSA when CRQCs arrive. The trade: ~50x larger signatures, fundamentally different security assumption (lattice vs discrete log). https://t.co/7F6231Nch1

3.4B people 'live under' launched CBDCs, but actual adoption stays low even with coercion. Nigeria's eNaira hit ~0.5% despite the 2022-2023 cash withdrawal that triggered riots. Pattern: cash suppression failing, not CBDC succeeding.

Worth distinguishing "launched" from "adopted." 3.4B "live under" CBDCs, but actual usage stays low even with coercion. Nigeria's eNaira reached ~0.5% adoption despite the 2022-2023 cash withdrawal that triggered riots and Supreme Court intervention. The pattern is cash suppression failing, not CBDC succeeding.

A block not accepted into the best chain, more accurately referred to as a stale or orphaned block.

@craigwarmke Architectural asymmetry: Starlink needs Starlink Inc.'s consent to stay working; Bitcoin needs no one's. The synergy is real ; 2022 Ukraine ran both, Starlink for comms + Bitcoin for donations. The pair is what dissidents under oppressive regimes have been building toward.

The sat is the protocol-level integer unit. Internally, Bitcoin Core tracks all balances and amounts in Satoshis.

Huge buried detail: BTC illicit volume is flat ~$10B while total adoption grew 3-4x. The % is shrinking faster than the absolute chart shows. Chain analysis maturity + price volatility = BTC is structurally bad for serious illicit use. The Silk-Road-era narrative is increasingly obsolete.

Excellent point: Efficiency isn't free. Centralized competitors get speed by accepting three long-term failure modes:

1. Corruption (capture)
2. Succession (single point of leadership)
3. Mission drift (entropy over generations)

Bitcoin avoids all three by construction. Over the right horizon, the trade flips.

SegWit took years. Taproot took years. The 2015-2017 block size war tried hard forks that failed at exactly these alignment steps.

A monetary system whose rules are easy to change is not a credible monetary system. Rough consensus is a feature.

"The people in charge of Bitcoin" - Five stakeholder groups. Each can veto a rule change by refusing to participate. No one is in charge. Everyone can refuse.

5/ Hodlers

The long-term economic majority. They don't sign blocks or write code.

Their veto: sell the new chain.

Miners earn what hodlers preserve. The chain with credible scarcity is the chain people refuse to sell.

@lopp The 2010 Value Overflow Incident is the canonical example. Block 74638 minted 184B BTC via integer overflow. No court fixed it; social consensus did. Patched in 5 hours, 53-block reorg, canonical chain rejected the exploit. Bitcoin's consensus is the court.

[LearnBitcoin.com @LearnBitcoincom]

The security implication: this is defense-in-depth against build supply-chain attacks. A Guix-toolchain compromise would go undetected if Guix is the only verification path. Two independent toolchains producing identical binaries makes single-supply-chain attacks much harder to land.

Historical precedent: Counterparty used this address for XCP proof-of-burn in Jan 2014: ~2,130 BTC sent over a month-long window to mint XCP. The 5-tx structure here suggests coordinated burn, not accident. Worth checking if any new Bitcoin-layer protocol announced proof-of-burn issuance recently.
