Figures and Works

Dr. Bright

Pen name of this book's author; completed in 2024. Taking Hayek's The Denationalization of Money as a mirror, it discusses the evolution of monetary order in the age of the value internet.

The Popularization of Money

This book's core concept: the creation and choice of value measures need no longer be monopolized behind a few gates; protocol standardization makes issuance rules open, participatory, and composable. The subtitle A New Chapter in Monetary Civilization: Tribal Tokens · State Fiat · Popular Protocol · Value in Direct Flow summarizes the civilizational history of coordination scale in four arcs; in intellectual lineage it takes Hayek's The Denationalization of Money as a counterpart, without advocating the abolition of exchange and settlement themselves.

Protocol and Asset Standards

PCIM (Public Currency Issuance Mechanism)

An over-collateralized public-domain currency issuance mechanism, also called the "new gold standard"—at the abstract layer: anyone holding agreed volatile collateral may, under open rules, competitively issue public currency pegged to fiat units with over-collateralization, with no single-point issuer. Collateral discipline uses dynamic tiers: circulation thresholds for each mapping trigger governance votes on the mint yield rate $\sigma$ (inverse of $C_0=100\%/\sigma$); if a vote fails, the prior tier is kept; the ordinary upper-tier ceiling is about $\sigma=61.8\%$, $C_0 \approx 161.8\%$; in a crisis a separate vote may raise $C_0$ and lower $\sigma$ to tighten (Chapter 14, Section 2.2). No MakerDAO-style liquidation/warning lines ($L$/$W$); stability rests on same-price oracles, mint/redeem arbitrage ($\varepsilon$), protocol reserves ($R$), and tier votes. Full English name: Public Currency Issuance Mechanism (not Public Competitive Issuance System).

Implementation example (Openverse): collateral Bitgold (BTG); public standard VRC-10 (Bitcurrency). When listed alongside DAI or USDC, PCIM names the mechanism class; Openverse names a deployment instance.

Mint yield rate $\sigma$ (VRC-10)

The share of Bitgold market value that may be minted as Bitcurrency face value per unit of collateral; $\sigma = 100\%/C_0$. Set by circulation tiers and governance votes, not a fixed constant. Bitcurrency-USD reference tiers: votes triggered at 1M / 10M / 100M / 1B USD circulation, deliberating $\sigma$ of 23.6%, 38.2%, 50%, 61.8% respectively (other mappings may configure different thresholds).

Circulation-tier governance vote (VRC-10)

Each VRC-10 mapping triggers dynamic-ratio votes by on-chain circulation $S$ for that mapping; if passed, switch to the deliberated tier; if rejected, the collateral ratio is unchanged. In crisis, votes may raise the collateral ratio (lower yield rate). VRC-10 only; VRC-11 does not participate.

$C(x)$ (post-shock collateral ratio)

After BTG falls $x$ relative to the oracle reference price, the collateral ratio of an isomorphic position: $C(x) = C_0(1-x)$. $C_0$ is the currently effective tier collateral ratio; at the upper tier $C_0 \approx 161.8\%$, $x^* \approx 38.2\%$ is the critical drawdown at which coverage falls below 100%.

$x^*$ (critical coverage drawdown, VRC-10)

The critical drawdown of Bitgold relative to the oracle reference price at which isomorphic-position collateral ratio $C(x)=C_0(1-x)$ falls below 100%: $x^* = 1 - 100\%/C_0$. At the upper tier $C_0 \approx 161.8\%$, $x^* \approx 38.2\%$—not a stake share, but a BTG price-shock threshold.

Oracle (PCIM)

Minting and redemption read the same on-chain TWAP (e.g. 1-hour window) plus a redundant median; if single-block price deviation exceeds threshold $\theta$, circuit-break—pause new minting while allowing top-up collateral and redemption.

Arbitrage bandwidth $\varepsilon$

The sum of fees, slippage, and delay on mint/redeem channels; when $x < x^*$, the upper bound on peg deviation is $\delta \leq \varepsilon$. Usually designed to be < 1%.

Peg deviation $\delta$

The proportional deviation of Bitcurrency's secondary-market price from its nominal peg unit (e.g. 1 dollar) (e.g. $\delta=0.03$ means 3% off-peg). The PCIM minimal model gives an upper bound on $\delta$: when $x < x^*$, $\delta \leq \varepsilon$; when $x \geq x^*$, $\delta \leq \varepsilon + \max(0,\, g(x)-R)$.

Liquidation line $L$ / warning line $W$

Typical MakerDAO/CDP parameters: forced auction when collateral ratio $C$ breaches $L$; warning near $W$. Neither VRC-10 nor VRC-11 sets $L$/$W$; $C(x)$ is used only to monitor coverage and as circuit-breaker input, and does not trigger on-chain forced auctions—under extreme stress the pressure path is redemption runs and reserve drawdown (public domain) or off-chain redemption runs (private domain), not Maker-style liquidation cascades. VRC-12 (Bitsecurity) may retain independent liquidation thresholds; do not conflate with VRC-10/11.

Collateral gap $g(x)$

The shortfall of on-chain hard collateral relative to debt face value after BTG falls $x\%$: $g(x)=\max(0,\,(100\%-C(x))/100\%)$. When $x \geq x^*$, peg pressure moves with $g(x)-R$ (reserve $R$). For VRC-11, from the first mint $g(0)=100\%-C_0=38.2\%$ (a structural gap, not requiring BTG to fall 38.2% before it appears); contrast with $x^*$ under "two kinds of 38.2%" below.

Protocol reserve $R$

Protocol reserves as a share of circulating Bitcurrency; when $x \geq x^*$ they can absorb the collateral gap so that peg-deviation upper bound $\delta \leq \varepsilon + \max(0,\, g(x)-R)$.

Two kinds of 38.2% (do not conflate)

(1) $x^ \approx 38.2%$*: under VRC-10 upper-tier over-collateralization, BTG's critical drawdown—the price-shock threshold at which coverage falls below 100%; upper-tier stake ratio about 161.8%, with 61.8% as excess buffer. (2) $g(0)=38.2\%$: VRC-11 under-collateralization's structural gap—from the first mint, on-chain hard collateral is already 38.2 percentage points short of face value. The numbers coincide with the golden ratio; the meanings are entirely different.

Over-collateralization / 61.8% excess buffer (VRC-10)

161.8% stake ratio (upper tier)

On the VRC-10 ordinary up-tier path's upper tier: at mint yield $\sigma=61.8\%$, minting 100 of Bitcurrency requires staking about 161.8 of Bitgold. Lower-circulation tiers are higher and more conservative (see circulation-tier governance votes). Applies only to the VRC-10 / PCIM public layer.

Under-collateralization / 61.8% stake ratio (VRC-11)

Minting 100 of Privcurrency requires staking about 61.8 of Bitgold—a 61.8% stake ratio. This is under-collateralization—collateral value below face value issued—forming a golden-ratio contrast with VRC-10's upper-tier ~161.8% over-collateralization ($\varphi^{-1} \approx 0.618$). Private-domain stability must layer enterprise reputation, whitelist constraints, and off-chain redemption; on-chain hard collateral alone cannot close the peg.

No liquidation line / no warning line (VRC-10 / VRC-11)

VRC-10 and VRC-11 neither adopt MakerDAO/CDP-style liquidation lines ($L$) or warning lines ($W$). Position collateral ratio $C = \text{collateral market value} / \text{debt face value}$ is used only to monitor coverage; VRC-10, under currently effective tier over-collateralization, maintains the peg via mint/redeem, circuit-breaker pauses, and reserves; VRC-11, at 61.8% under-collateralization, layers enterprise reputation, whitelists, and off-chain redemption. Other standards such as VRC-12 (Bitsecurity) may retain independent liquidation thresholds; do not conflate with VRC-10/11.

PCIM minimal peg model

Comparative statics under a one-period isomorphic-position framework: post-shock collateral ratio $C(x) = C_0(1-x)$; critical coverage drawdown $x^* = 1 - 100\%/C_0$ (about 38.2% for VRC-10). When $x < x^*$ and redemption channels work, peg deviation $\delta \leq \varepsilon$ (arbitrage bandwidth); when $x \geq x^*$, gap $g(x)=\max(0,\,100\%-C(x))$, $\delta \leq \varepsilon + \max(0,\, g(x)-R)$ (when reserve $R$ can absorb)—not on-chain forced liquidation. VRC-11 under-collateralization requires separate assessment of off-chain credit risk. The model gives an upper bound on $\delta$, not a promise; given observed $\delta$ and $x$, one can back out which chain—arbitrage, reserve, or oracle—has failed. Three mechanism chains—oracle pricing, over-collateralization constraint, mint/redeem arbitrage—jointly yield the upper-bound function for peg deviation.

PCIM peg theorem (one sentence)

After BTG falls $x\%$, $C(x)=C_0(1-x)$; when $x<x^*$, $\delta\leq\varepsilon$; when $x\geq x^*$, $\delta\leq\varepsilon+\max(0,\,g(x)-R)$—VRC-10 is an over-collateralized CDP (DAI-like), substituting redeem arbitrage + reserves for forced liquidation; at the public layer 38.2% is BTG's critical drawdown $x^*$, at the private layer a structural gap $g(0)$—do not conflate. Also called the Bright–PCIM peg bound.

Bright–PCIM peg bound

VRC-10 peg-deviation upper-bound theorem: $C(x)=C_0(1-x)$; $x<x^*\Rightarrow\delta\leq\varepsilon$; $x\geq x^*\Rightarrow\delta\leq\varepsilon+\max(0,\,g(x)-R)$. Same formula as "PCIM peg theorem (one sentence)"; given on-chain $x$ and observed $\delta$, back out which of arbitrage, reserve, or oracle has failed. Full English mechanism name: Public Currency Issuance Mechanism.

PCIM model variables

Liquidation mechanism: MakerDAO/DAI triggers on-chain forced auctions when $C < L$—March 2020 "Black Thursday" showed that liquidation itself can amplify the fall. VRC-10 and VRC-11 neither set $L$/$W$; $C(x)$ is monitoring and circuit-breaker input only and does not trigger on-chain auctions. Under extreme markets the pressure path is redemption run + reserve drawdown (public) or off-chain redemption run (private), not Maker-style cascade liquidation. VRC-12 (Bitsecurity) retains independent CDP liquidation thresholds—securities-layer risk is separate; do not conflate with PCIM public/private domains.

Three-chain closure (VRC-10 peg architecture)

The PCIM peg closes jointly through three chains; none is dispensable: (1) oracle chain—mint/redeem read the same TWAP + redundant median + anomaly circuit-breaker; (2) collateral chain—$C_0$ is the current tier (must be $>100\%$ for over-collateralization), no $L$/$W$; (3) arbitrage chain—when $x<x^*$, mint/redeem constrain $p$ to $[1-\varepsilon,\,1+\varepsilon]$.

VRC-10 / Bitcurrency

Public-domain currency standard. Competitively issued via Bitgold dynamic-tier over-collateralization, pegged to ISO 4217 fiat units (upper-tier stake ratio about 161.8%), for cross-ecosystem stable settlement. Global primary circulating media means VRC-10 only, not VRC-11 Privcurrency.

Exit of inferior money

Under parallel competition without forced parity, fiat with mismanaged monetary policy and its on-chain mappings lose C-money functions (cross-border settlement, open-ecosystem pricing, long-term store of value) because holders, merchants, and protocol routers do not voluntarily choose them—"bad money drives out bad money" in the literal competitive sense, not Gresham's forced-parity mechanism. Exit is functional marginalization, not the physical disappearance of symbols or domestic legal tender.

Reserve–circulation division of labor

Functional layering of public C-money: the reserve layer is fixed-supply Bitgold (BTG), unified collateral and POS stake; the circulation layer is a few (not pre-assigned by nationality) VRC-10 Bitcurrencies, carrying dynamic global medium and unit-of-account roles. Reserves should be "one"; circulation should be "few."

VRC-11 / Privcurrency

Private-domain stablecoin standard. For enterprises or closed trade circles, minted with Bitgold under-collateralization (61.8% stake ratio); permissioned whitelist circulation; names such as StarUSD, MicroUSD.

VRC-12 / Bitsecurity

Equity-type token standard. Enterprises stake Bitgold to issue; may map real-world assets (RWA) on-chain.

Bitgold (BTG)

Openverse native standard asset; total supply about 200 million, with roughly three-year halvings. As PCIM collateral, POS stake, and fee carrier, it underpins public- and private-domain currency issuance.

bit gold (Szabo's conception)

Nick Szabo's 2005 conception of online "bit gold" with verifiable scarcity: proof of work creates unforgeable scarce bits, distributed property title registration, and timestamp chains—a precursor to Bitcoin ideas; 1997's "The God Protocol" is a precursor to verifiable third-party substitution; 1999's "Trusted Third Parties Are Security Holes" is its institutional corollary; Finney's 2004 RPOW is an engineering middle step; 2017's "social scalability" aligns with this book's second dimension of "verifiability"; this book's appendix includes the bit gold original.

b-money (Wei Dai's conception)

Wei Dai's 1998 conception of distributed ledgers and proof of work; acknowledged in the References of Satoshi Nakamoto's Bitcoin white paper. A precursor link in the Nakamoto–Back–Szabo idea chain.

The God Protocol

Nick Szabo's 1997 concept: "God knows the outcome; humans can only verify"—an institutional precursor to verifiable third-party substitution, in the same lineage as bit gold and smart contracts.

Hashcash

Adam Back's 2002 proof-of-work mechanism against spam; Satoshi Nakamoto's Bitcoin white paper §4 embeds it in monetary issuance discipline.

RPOW (Reusable Proofs of Work)

Hal Finney's 2004 engineering prototype based on bit gold ideas: transparent server + remote attestation to verify work—a middle link between Szabo's conception and Nakamoto's chained ledger.

social scalability

Nick Szabo's 2017 concept: blockchain money's value lies in replacing interpersonal trust costs with verifiable rules, so strangers can collaborate without knowing each other—aligned with this book's second emergent dimension of "verifiability."

Filecoin (FIL)

Protocol Labs' decentralized storage network (storage-type DePIN), organizing storage delivery with Proof-of-Replication and proof of spacetime, with FIL incentivizing nodes.

Openverse (Layer 0, value-exchange layer)

Openverse is designed as Layer 0—a globally decentralized value-exchange layer: at the protocol layer it provides POS consensus, final-settlement anchoring, Bitgold staking, PCIM public issuance, VTP value routing, and cross-domain interoperability, so that Ethereum, Cosmos chains, consortium chains, and in-ecosystem application chains and other Layer 1 networks can all connect. In white-paper engineering terms, Hub Chain corresponds to the Layer 0 core chain (consensus and clearing anchor, not hosting application smart contracts); Zones correspond to native Layer 1 application chains within the ecosystem—an implementation layering, not the full architectural boundary.

VTP (Value Transfer Protocol)

The routing protocol of Openverse's Layer 0 value-exchange layer, analogous to HTTP for information networks, responsible for cross-chain and cross–Layer 1 value addressing, transfer, and finality confirmation.

DeFi Stability Mechanisms and Comparative Terms

CDP (Collateralized Debt Position)

An on-chain over-collateralized lending position: users lock crypto assets and borrow stablecoins at a collateral ratio; forced auction when the ratio breaches the liquidation line (typical MakerDAO/DAI design). VRC-10 belongs to the CDP family on the over-collateralization dimension but sets no liquidation/warning lines.

DAI

MakerDAO's decentralized over-collateralized stablecoin, collateralized by ETH and other on-chain assets, with parameters adjusted via liquidation lines and on-chain governance. PCIM/Bitcurrency belongs to the same over-collateralized CDP family in mechanism lineage, but with different parameters and risk paths.

Anchor Protocol

High-yield deposit protocol in the Terra/UST ecosystem; ~20% UST deposit APY subsidized by ANC token inflation (source: official white paper; not independently audited). When subsidies prove unsustainable, large holders exit first, compounding the UST death spiral.

Reserve redeemability

Lyons & Viswanath-Natraj (2020) framework: stablecoin pegs depend not only on reserve statements but on whether holders can redeem at face value in time; pegs are more fragile when OTC depth is thin. Ferraro, Kan & Sunderam (2022) add a "thin markets" dimension.

sophisticated-first exit

Liu, Makarov & Schoar (2023) on-chain evidence: in early UST depeg, large, high-information participants exited before retail; timing aligns with Anchor high-yield subsidies becoming unsustainable.

Algorithmic vs over-collateralized (stability-mechanism spectrum)

Ortiz & Witte (2023) ex-post comparison: algorithmic stablecoins (e.g. UST) redeem significantly faster under stress than over-collateralized CDPs (e.g. DAI)—the former are "confidence-collapse runs," the latter "collateral-shrinkage runs." Bullmann, Klemm & Pinna (2019) ECB three-dimensional classification (issuer accountability, decentralization of responsibility, collateral) further shows a systematic trade-off between algorithmic "innovativeness" and peg capacity. Assessment must classify first; do not conflate.

Co-instability

Gadzinski et al. (2024) structural-break and co-occurrence analysis of a multi-stablecoin panel: in Terra/LUNA, IRON/TITAN and similar events, algorithmic types were the primary receivers of shocks; fiat-collateralized and crypto over-collateralized CDPs were relatively more resilient after shocks—read separately from single-protocol TVL narratives.

Maker Endgame

MakerDAO's 2023 protocol-restructuring plan: split Maker into SubDAOs, restructure the MKR governance token, and continue post–Black Thursday evolution of liquidity modules such as D3M. Source: official Endgame Litepaper v1; not independently audited.

Algorithmic stablecoin

Pegs maintained mainly via dual-token burn/mint, algorithmic balance-sheet expansion, or high-yield subsidies, rather than hard collateral coverage consistently above 100%. Terra/UST (2022 collapse) is the canonical counterexample.

Death spiral

Under depeg pressure, an algorithmic stablecoin absorbs stablecoin supply by minting more of its native coin, further depressing the native price and deepening the depeg in a self-reinforcing loop. The 2022 UST/LUNA collapse is the landmark case.

Black Thursday

12 March 2020 ETH crash triggering MakerDAO liquidation spirals, zero-bid auctions, and DAI premium; the same day the Fed injected large liquidity. A comparative case of protocol money lacking a lender-of-last-resort function.

Verifiability

The second dimension of monetary emergence in the digital age (alongside Menger's "saleability"): whether rule execution, on-chain state, and history can be independently checked at low cost by any third party (including programs). Szabo (2017) "social scalability" states the same requirement from an institutional-collaboration angle.

Saleability

Core concept in Menger's origin-of-money theory: goods gain advantage as media of exchange by being more divisible, portable, and widely demanded; paired with verifiability.

CBDC and Digital Sovereignty

CBDC (Central Bank Digital Currency)

The digital form of central-bank liabilities, split into wholesale (inter-institution clearing) and retail (facing the public). BIS 2020 seven-central-bank principles position it as a digital extension of cash, not a replacement for commercial-bank credit intermediation.

Retail / wholesale CBDC

Retail CBDC faces individuals and firms directly and may trigger deposit disintermediation; wholesale CBDC upgrades the interbank final-settlement layer with limited public impact—Carapella & Fleischman (2020) position it as payments-system innovation, far less politically contested than retail disintermediation. Niepelt (2024) aligns the taxonomy with policy questions such as "can the public redeem public money at face value" and "can non-banks access central-bank liabilities."

Deposit disintermediation

The public shifts commercial-bank deposits into CBDC (direct central-bank liability, no counterparty risk), compressing banks' credit-creation base. Bindseil (2024) and Auer et al. (2022) note that shock size depends heavily on whether CBDC pays interest and whether holding caps apply—with zero interest and roughly €3,000 per-person caps, euro-area absorption is on the order of trillions of euros.

Payment-type / investment-type CBDC (Bindseil layering)

Payment-type CBDC is non-interest-bearing with holding caps, mainly a cash extension; investment-type CBDC pays interest, may strengthen policy-rate pass-through to bank liabilities, but also hardens the zero lower bound. The ECB digital-euro legislative draft leans toward payment-type design.

Tiered CBDC

Bindseil (2020) interest-tiering design: everyday payment balances keep zero or very low rates; holdings above a threshold face lower (even negative) CBDC rates, making CBDC marginally inferior to bank deposits and limiting disintermediation incentives.

Tiered privacy

Bindseil and Panetta (2021) privacy–compliance compromise for retail CBDC: small-value offline anonymity, large-value online auditability—alongside holding caps and waterfall mechanisms in the digital-euro legislative draft as control devices.

Waterfall mechanism

Companion to holding caps in the digital-euro legislative draft: excess CBDC balances automatically transfer back to bank accounts, preventing CBDC from becoming a store-of-value asset competing with government bonds. Kumhof & Noone (2021) list it among financial-stability design principles.

Unified ledger

BIS (2023) The Future Monetary System vision of programmable financial infrastructure: wholesale CBDC, tokenized deposits, and on-chain assets settle atomically on the same stack—not replacing banks with CBDC, but juxtaposing the final-settlement layer with a composable contract layer.

mBridge

BIS-led multilateral wholesale CBDC platform (Hong Kong SAR, Thailand, UAE, mainland China, and others), entering MVP in 2024, targeting cross-border PvP atomic settlement. Functionally overlaps on-chain stablecoins in remittance use cases; diverges on compliance and sovereign control.

Brunnermeier–Niepelt equivalence proposition

Under particular fiscal–central-bank coordination and frictionless assumptions, introducing CBDC can be equivalent to "central bank direct liability to the public + corresponding adjustment of the banking system," theoretically leaving the monetary-policy stance unchanged; once deposits flee into CBDC in a crisis, or CBDC pays interest without holding caps, the equivalence conditions fail.

Distributional Effects and Political Economy

Cantillon effect

Newly created money is distributed non-uniformly along injection paths: agents near the issuance channel gain purchasing power first; distal agents feel the increase only after prices rise, by which time new purchasing power has already been diluted by first movers. Cantillon (c. 1730) Ch. 7; contemporary QE distributional evidence.

Democracy in Deficit

Buchanan & Wagner (1977): democratic political incentives raise spending and cut taxes in booms, then stimulate again in recessions, while austerity is politically unpopular—producing a cross-cycle bias toward deficits and monetary expansion.

Agent Economy and M2M Settlement

M2M (Machine-to-Machine settlement)

Value transfer completed by programs under preset rules without step-by-step human approval; granularity down to a single API call or GPU-second intervals.

x402

HTTP 402 micropayment protocol (2025): server returns PAYMENT-REQUIRED; client Agent signs and retries with PAYMENT-SIGNATURE; facilitator completes on-chain stablecoin settlement. Constraint carrier is facilitator reputation.

MCP (Model Context Protocol)

Anthropic's Nov 2024 Agent tool-orchestration standard: tools/list/tools/call under JSON-RPC semantics standardize tool calls; orchestration layer separated from settlement layer—payments must close separately via x402/AP2 and the like.

A2A (Agent2Agent)

Google's 2025 standard for Agent discovery, task delegation, and capability cards; complementary to AP2 payment-authorization chains.

AgentKit

Coinbase Developer Platform (Nov 2024) on-chain toolkit for Agents: framework-agnostic action providers, integrated with x402 for autonomous payment; custodial wallets reintroduce reputation constraints.

AP2 (Agent Payments Protocol)

Google's 2025 open Agent payment standard: Verifiable Credentials and Intent/Cart/Payment Mandates build an auditable authorization chain, extending A2A/MCP; constraint carriers are mandate signatures and issuer risk controls.

TAP (Trusted Agent Protocol)

Visa 2025 pilot: based on RFC 9421 HTTP message signatures, letting merchants cryptographically verify Agent identity and authorization; constraint carriers are card-network registration and public-key registries.

Agent Pay (Mastercard)

Mastercard's April 2025 agentic commerce offering: Agentic Tokens bind Agent identity and session limits (Know Your Agent); constraint carriers are card-network tokenization and issuer risk controls.

Lightning Network

Poon & Dryja (2016) Bitcoin off-chain payment-channel network, easing BTC main-chain throughput and micropayment friction; settlement still anchors to volatile BTC.

ERC-4337 / Account Abstraction

Ethereum account-abstraction standard: smart-contract wallets express spending rules in code (whitelists, limits, session keys); Agents submit "intents" that contracts adjudicate and execute.

DePIN (Decentralized Physical Infrastructure Networks)

On-chain order books and stake-slash organize trade in physical resources such as compute, bandwidth, storage, and wireless coverage (Akash, Render, io.net, Helium, Bittensor, and others). Delivery proofs are often off-chain; pricing often in volatile tokens; taxonomy in Ballandies et al. (2023).

soulbound token

Non-transferable on-chain credentials for Agent/node reputation, permissions, or completion records; conceptual framework in Weyl–Ohlhaver–Buterin (2022).

New Keynesian and Fiscal–Monetary Games

Flexible Inflation Targeting (FIT)

Central banks include both inflation and employment (output) gaps in the reaction function, trading off price stability against real fluctuations; Galí (2015) frames it as the main institutional form of internalizing distributional concerns within a discretionary framework; Taylor (1993) and Clarida–Galí–Gertler (1999) supply empirical benchmarks and formal surveys.

Taylor rule

Taylor's (1993) monetary-policy reaction function: the policy rate should adjust systematically with inflation and output gaps—becoming the empirical benchmark for New Keynesian "science" and many inflation-targeting regimes, between Friedman's k% fixed rule and pure discretion. Orphanides (2003) shows with historical data that actual policy often systematically departs from the rule-implied path.

Fiscal–monetary active–passive mix (Leeper 1991)

Leeper distinguishes which of monetary and fiscal policy "actively" sets the path and which "passively" accommodates: under "active fiscal, passive monetary" equilibrium, public-debt expansion is more likely to be fulfilled via inflation than tax adjustment—aligned with Sargent–Wallace (1981) unpleasant monetarist arithmetic.

Effective Lower Bound (ELB)

When the nominal policy rate nears zero, further cuts are constrained and the price tool of monetary policy loses force; Woodford (2003) and Eggertsson–Woodford (2003) argue that moderately positive inflation lowers the probability of hitting the ELB and supplies a welfare basis for roughly 2% inflation targets.

unpleasant monetarist arithmetic

Sargent and Wallace (1981): under high fiscal deficits, if the central bank long accommodates fiscal financing at low rates, higher inflation must eventually dilute the debt; programmable interest-bearing CBDC without caps may accelerate that path. Woodford (1996) gives the mirror constraint from public-debt dynamics: long-run price stability requires sufficient discipline on the debt stock. Canzoneri, Cumby, and Diba (2001) state the same logic as a fiscal solvency anchor.

Fiscal dominance

When public debt is large enough that monetary policy must prioritize debt sustainability, a nominally independent central bank is substantively fiscally constrained—rate hikes may trigger a government interest-expense crisis; rate cuts may tolerate inflation. Leeper's (1991) active–passive mix and Canzoneri et al. (2001) fiscal solvency anchor formalize the idea; Bassetto & Messer (2013) discuss contemporary versions under crisis unconventional operations.

Fiscal solvency anchor

Canzoneri, Cumby, and Diba (2001) AER 91(5): the long-run price level must be consistent with public-debt solvency; under active-fiscal, passive-monetary equilibrium, inflation becomes the equilibrium outlet for debt dilution—aligned with Leeper (1991) and Sargent–Wallace (1981). Sims (1994) Fiscal Theory of the Price Level (FTPL) gives a minimal model.

Fiscal Theory of the Price Level (FTPL)

Sims (1994) minimal model: the price level is jointly determined by the fiscal path (tax and debt dynamics) and the monetary-policy regime; when fiscal policy is active, inflation can be an equilibrium adjusting variable. Read with Leeper's active–passive mix.

New Keynesian synthesis

Ball, Mankiw, and Romer (1988) knit nominal rigidities, rational expectations, and policy rules into a unified framework; Woodford (2003) and Galí (2015) develop it into welfare arguments for roughly 2% inflation targets and FIT; Walsh (2017) textbook Ch. 8–11 supplies teachable, estimable operational formulations.

Time inconsistency

Kydland and Prescott (1977): if optimal plans can be revised period by period, policymakers may depart from ex-ante optimal commitments; inflation targeting and operational central-bank independence can be read as institutional responses that strip rate decisions from the electoral cycle.

Good/Bad Competition and Free Banking (Part II)

Gresham's Law

Under legal parity (law-forced fixed exchange rates), overvalued bad money drives out undervalued good money—holders spend bad first and hoard good. Hayek stresses: it applies only under forced parity and must not be called an "inversion" of Thiers' direction under free float; contrast Rolnick–Weber (1986) empirics.

Gresham's Fallacy

Rolnick & Weber (1986) term: statistically alleged "bad drives out good" often fails in free-banking periods without forced parity—when discount is allowed, the direction aligns with Thiers. Mutually corroborating with Hayek's distinction at pp. 42–43.

Thiers' Law

Under free float without forced parity, currencies with continually worsening purchasing power are actively abandoned and relatively stable ones retained—good drives out bad. Argentina, Zimbabwe, Venezuela, and discount-clearing logic in free-banking literature align; Rolnick & Weber (1986) contrast it with Gresham by institutional premise, not as an "inversion" of the same law.

Free Banking

Historical institutional experiments in which private banks competitively issue notes under limited regulation and clear spontaneously. Scotland (1716–1845) and the positive narratives of U.S. economic historians White and Selgin, versus causal doubts from Rockoff, Calomiris, and Kroszner, form a historiographical debate; this book's stance: discipline can be partly endogenized in clearing networks, but depends on gold-standard shadows, lender-of-last-resort expectations, and judicial enforceability—on-chain verifiable rules fill an identification-cost gap; Selgin (1984) evolutionary model and White (1984) option clause appear under free-banking entries in the bibliography.

Option Clause

Liquidity management spontaneously adopted by Scottish free banks: under stress a bank could defer coin redemption of notes for six months while paying compensatory interest (usually 5%). Selgin and White treat it as one endogenous stabilizer of competitive issue; Calomiris questions whether it could operate independently once stripped of the Bank of England lender-of-last-resort shadow. White (1984) ch. 2, pp. 40–52 is a checkable page citation.

Clearinghouse (interbank clearing network)

Multilateral note clearing and discount-reflux mechanisms spontaneously formed by banks in the free-banking era; Timberlake (1984) and Dowd (1993) treat them as institutional embryos of supply discipline endogenized by competitive issue—full nodes on-chain structurally fill the same gap.

Bank Note Reporter

Nineteenth-century U.S. publications by which merchants authenticated and discounted state banknotes; Rockoff (1974) and Dwyer (1996) use their records to analyze wildcat banking and high-information-cost competition.

Wildcat Banking

In the U.S. free-banking era, locating headquarters in remote areas to reduce redemption requests while issuing heavily into distant cities. Dwyer (1996) shows the essence was arbitrage on authentication and redemption costs—surface outcomes sometimes resemble Gresham-style retention of inferior notes, but the trigger is information cost, not legal parity.

Par Laws

Legislation forcing notes to be accepted at face value and forbidding discount circulation. Rockoff and Selgin's historiography shows: par laws re-embed Gresham mechanisms in private banking—inferior notes stay in circulation. Structurally isomorphic to incentive distortions of on-chain "forced 1:1 pegs"; Selgin (2010) on the 1865 federal tax suppressing state banknotes.

Institutions and Comparative Concepts

Mint prerogative

The institutional power of a single actor to monopolistically define the unit of account and extract implicit revenue from dilution. This book seeks to dissolve the monopoly of the mint prerogative, not the existence of money as a medium of exchange.

Denationalization of money

Hayek's 1976 claim: abolish the central-bank monopoly of note issue and let private monies compete freely. This book builds on that to discuss protocolized, verifiable contemporary implementation paths.

Value internet

The long-run vision of open standards completing cost reduction and routing for value transfer; VTP, the VRC standard family, and multi-chain interoperability (e.g. IBC) form part of its tech stack.
