Show Notes: Hash Rate - Lynn Alden on Broken Money, Bitcoin, and the Future of Finance
This episode unpacks the technological evolution of money, revealing how the shift from physical gold to telegraph-based IOUs created systemic vulnerabilities that Bitcoin aims to solve, offering critical insights for Crypto AI investors navigating today's financial landscape.
The Technological Shift: From Gold to "Morse Money"
- Host Mark Jeffrey introduces guest Lynn Alden, author of "Broken Money," praising it as a seminal work on the nature of money. The discussion begins by exploring a pivotal moment in monetary history: the transition from gold to telegraph-based financial messaging.
- Lynn Alden explains her motivation for writing "Broken Money" stemmed from observing how technology, often overlooked in traditional monetary histories focused on political decisions, fundamentally alters what we use as money and how we interact with it. She identifies the telegraph as a key technological catalyst.
- Before the telegraph (invented ~1830s, widespread ~1860s-early 1900s), transaction speeds were only marginally faster than settlement speeds. Settlement refers to the final, irreversible transfer of the actual asset (like physical gold). Technologies like coinage and paper improved transaction efficiency, but everything ultimately moved at the "speed of gold."
- The telegraph created a new era by enabling near-instantaneous transactions (sending IOUs or instructions) globally, while the underlying settlement (moving gold) remained incredibly slow and costly. Lynn cites Germany's multi-year, multi-million dollar gold repatriation effort as a modern example of slow physical settlement.
The Transaction vs. Settlement Speed Gap and Centralization
- This vast difference between transaction speed (light speed) and settlement speed (speed of ships/trains) fundamentally changed money's nature. Lynn argues this gap empowered the middlemen—banks and central banks—who managed the fast-moving digital ledgers representing claims on slow-moving gold.
- Mark highlights a key point from Lynn's book: these telegraphed IOUs began to be perceived and valued more than the underlying gold itself due to their speed and utility in commerce.
- Lynn introduces William Stanley Jevons, an economist writing in 1875, who marveled at the efficiency of telegraphic money enabling vast sums to move globally based on netting IOUs, with minimal physical gold movement. Jevons saw the potential for hyper-centralization, envisioning layers of banks settling through a central bank, ultimately culminating in London as the global financial center.
Leverage, Fragility, and the Role of War
- Jevons, despite praising the efficiency, also issued a stark warning. Lynn quotes his observation from 1875: "This is so efficient that... if you look at UK right now... it's leveraged 20 to 1. Like if 5% of people want their gold back, they can't have it." This highlights the inherent fragility introduced by fractional reserve banking, where banks hold only a fraction of deposits as actual reserves (gold in this era) and lend out the rest, creating more claims (money) than base assets.
- Banks operate on mismatched assets and liabilities. While they hold assets backing deposits, only a small portion might be physical gold; the rest are loans (promises to be repaid in gold). This works until confidence falters or a systemic shock occurs, leading to bank runs. Jevons' warning proved prescient, as this highly leveraged system collapsed during World War I.
- Mark raises Lynn's point that pre-telegraph wars were constrained by physical gold reserves. The new system, allowing governments to create money beyond physical stockpiles, enabled conflicts on an unprecedented scale. Lynn explains that World War I likely couldn't have happened in its eventual form without this financial technology.
- Lynn details how the UK, needing funds for WWI but facing low public demand for war bonds, deceptively claimed the bonds were oversubscribed while secretly having the central bank print the necessary money. This "invisible tax" confiscated purchasing power from savers globally (as the UK pound was the reserve currency) to fund the war effort, a capability impossible in the gold-only era.
The Nixon Shock and the Dollar's Dominance
- The discussion moves to the 20th century, noting the Vietnam War's financial strain on the US. This culminated in the 1971 "Nixon Shock," where the US unilaterally suspended the dollar's convertibility into gold, effectively ending the Bretton Woods system and ushering in the modern era of fiat currency (money declared by a government to be legal tender, not backed by a physical commodity).
- Lynn clarifies the break was driven by both fiscal pressures (war spending) and the inherent instability of the fractional reserve system built atop gold. By the late 1960s, US dollar liabilities held abroad significantly exceeded US gold reserves, making the system unsustainable as foreign entities redeemed dollars for gold. The system's design flaws, Lynn argues, made the 1971 break inevitable.
- Despite being "softer" money (easier to create) than gold, the US dollar supplanted gold globally. Lynn attributes this to speed (dollars moved electronically, gold didn't) combined with existing network effects (the Eurodollar market - dollars held outside the US) and deliberate policy (the Petrodollar system, creating demand for dollars to buy oil). "This is the first time where say gold and dollars ran into each other and the softer one dollars... pretty much won out... because this was the first time where speed mattered."
Bitcoin: Closing the Gap? The Third Era of Money
- Mark pivots to Bitcoin, noting Lynn's book treats it analytically, not as pure advocacy. He highlights Bitcoin's key difference: it allows transferring the actual digital asset at near light speed, unlike the IOU systems of the past. It combines the finality of settlement with the speed of digital transmission, offering transparency (public ledger) versus opaque gold reserves.
- Lynn posits that Bitcoin represents the potential start of a "third era" of money by inventing fast settlement. It closes the transaction/settlement speed gap that defined the telegraph era, reducing reliance on centralized ledger keepers.
- She emphasizes Bitcoin wasn't a sudden invention but built on decades of cryptographic and computer science work (David Chaum's early concepts, Adam Back's proof-of-work, Nick Szabo's Bit Gold, Hal Finney's reusable proof-of-work). Satoshi Nakamoto synthesized these pieces when technology (SHA-256 encryption, sufficient global internet bandwidth) made it feasible. Early criticisms, Lynn notes, centered on bandwidth limitations, showing Bitcoin emerged about as early as technologically possible.
Bitcoin's Challenges: Scaling and Quantum Threat
- Despite its innovation, Bitcoin faces limitations, primarily scaling. Decentralized digital settlement cannot scale infinitely, analogous to not storing every email ever sent on every computer. Lynn states, "Do you want your coffee transaction to be like a part immutable part of like human history now like probably not." This necessitates layered solutions.
- The conversation shifts to the significant threat of quantum computing, which could potentially break Bitcoin's underlying encryption (specifically, deriving private keys from public keys). Mark mentions Chimath Palihapitiya's 2-5 year estimate, though Lynn suggests it might be further out but still requires serious attention.
- A critical challenge is migrating the entire Bitcoin network to quantum-resistant addresses. Mark cites Fred Krueger's point that this migration could take years due to network congestion, making proactive solutions crucial. Lynn agrees the timeline is relevant and the transition complex, potentially taking longer than a year.
- Lynn offers nuance: early quantum attacks might be prohibitively expensive ($1M+ per crack), initially threatening only large UTXOs (Unspent Transaction Outputs - the specific chunks of bitcoin being tracked on the ledger) like those held by whales or exchanges. This might provide a buffer for smaller holders, but the cost-effectiveness of attacks will likely improve over time. Mark expresses concern that Bitcoin Core developers might not be treating this threat with sufficient urgency, calling for a "Manhattan project" level effort.
- Further complexities include quantum-resistant signatures potentially requiring more data, impacting transaction throughput, and the controversial question of whether to eventually lock or "burn" unmigrated coins (like Satoshi's) to prevent them from being quantum-hacked, which raises censorship concerns.
The Current Dollar System: Turtles All The Way Down?
- Mark probes the fragility of the current dollar system, referencing Lynn's "turtles all the way down" analogy – a system ultimately backed by itself. He describes how banks create money via lending (especially post-COVID removal of reserve requirements) and how the government borrows money (Treasuries) and prints the interest payments, comparing it to a large-scale Ponzi scheme.
- Lynn agrees with the circularity, noting the Federal Reserve's base money is backed by Treasuries, which are themselves IOUs for dollars. However, she differentiates it from something like Terra/Luna, emphasizing that rules, regulations, institutional checks ("multisigs" involving multiple entities needing to agree), and frictions slow down money creation in the dollar system, preventing immediate hyperinflation unlike more fragile systems. These controls can be loosened during crises (2008, COVID).
- Commercial banks create broad money through lending, constrained by capital and liquidity rules. The Federal Reserve controls the base money supply. While debasement occurs, it's generally gradual, maintaining credibility.
- Regarding a potential collapse triggered by entities refusing to buy US Treasuries, Lynn believes we are "a ways from that." While foreign official buying has slowed (China pivoted around 2013), the massive amount of global dollar-denominated debt ($13T+) creates structural, inflexible demand for dollars, acting as a brake on rapid debasement. She anticipates ongoing, gradual debasement rather than hyperinflation or austerity within a 5-10 year horizon.
Potential Fixes and Political Realities (Trump/Elon)
- Mark outlines the US fiscal imbalance (spending $7T, revenue $5T) and potential Trump/Elon Musk aligned efforts to cut deficits (aiming for $1-2T cuts) and increase revenue (tariffs). He asks if these are the right steps.
- Lynn concurs with the "slow motion bankruptcy" assessment and acknowledges the intentions are correct. However, she highlights the difficulty: most spending growth is in politically sensitive areas (Social Security, Medicare, Defense, Interest), not easily cuttable discretionary spending. Cutting these faces immense political hurdles.
- She analyzes the trade deficit issue, explaining the dollar's reserve status creates artificial demand, allowing the US to run structural trade deficits, which hollowed out the US industrial base (the "Rust Belt"). Trump's focus on tariffs and restructuring trade aims to address this imbalance, which has become a political and national security concern. There's intellectual backing (e.g., Stephen Miran's work) behind the tariff proposals.
- However, Lynn cautions about unintended consequences. Austerity measures or aggressive tariffs could negatively impact asset prices, which in turn would reduce US tax receipts (due to high correlation), potentially offsetting much of the intended deficit reduction. The system is a "Gordian knot," extremely difficult to untangle.
- Lynn notes the renewed focus on debt is driven by rising interest expenses (as rates are no longer falling) and the cumulative political impact of decades of trade deficits (evidenced by the Rust Belt's political realignment). While attempts to "hack at the knot" are now happening, the multi-decade nature of the problem suggests it will require sustained effort and multiple attempts.
Bitcoin Lightning Network: Scaling in Practice
- The discussion concludes with a practical look at the Bitcoin Lightning Network, a Layer 2 scaling solution. Mark recounts his recent experience using Lightning at Lynn's prompting, admitting it was better than expected.
- Lynn explains Lightning aims to address Bitcoin's throughput limitations by allowing users to open payment channels off-chain. Transactions within these channels are near-instant and cheap, settling finally on the main Bitcoin blockchain only when channels are closed. This mimics systems like Fedwire, which settles vast sums ($1 quadrillion/year) with relatively few transactions (~200M/year, similar to Bitcoin's base layer throughput) because the average transaction value is huge.
- Lightning channels are essentially pre-signed multisig contracts allowing balances to be shifted between parties. These channels can be networked, allowing payments to be routed through intermediaries for a small fee, creating an interconnected web.
- Mark raises concerns about usability (needing specific Lightning addresses/apps like Strike) and the lack of a traditional block explorer for tracing stuck transactions. Lynn explains that outside of custodial solutions like Strike, non-custodial Lightning requires managing channels and liquidity, often using Lightning Service Providers, which can involve more friction but offers greater self-sovereignty.
- Regarding transaction size limits (Mark notes ~ $5k practical limit), Lynn clarifies this is a network effect limitation (insufficient liquidity currently), not a technical one. Large channels between institutions are possible but depend on demand and security considerations for large "hot wallet" balances. The practical limit has increased significantly over the past few years.
- Lynn expresses bullishness on Lightning as a crucial middle layer in a scaling "stack" that also includes custodians (like Cash App) for ease of use and potentially Chaumian eCash protocols (like FediMint, Cashu) built atop Lightning for enhanced privacy. She highlights the flexibility: users can choose between custodial convenience, non-custodial control, or privacy-focused eCash, depending on their needs. She cites sending funds privately to the anonymous developer 'Calle' via Lightning/eCash as an example of its unique capabilities.
Conclusion: Navigating the Third Era of Money
The conversation underscores how technological advancements continuously reshape finance, revealing the inherent trade-offs between speed, settlement finality, centralization, and privacy. For Crypto AI investors and researchers, understanding this historical context and the capabilities/limitations of emerging solutions like Bitcoin and its layers is crucial for navigating the evolving landscape and identifying long-term value. Monitoring developments in scaling, privacy tech, and quantum resistance is paramount.
