Imagine further that you’re owed a refund on your recent tax payment,orareawaitingapaycheckorsomepublicbenefit,orareborrowing from a bank or community development financial institution (“CDFI”) to start-up a business or grow a business you already operate. Presently these multiple transactions will likely occur over multiple “plat- forms”or“networks,”andwillrequiremultiple“paymentmedia”toproceed. You might pay the house-sitter in paper currency or over Venmo, say, then use a chip card or strip card at the store, slip coins into a parking meter, and send a check to a broker or tax authority. Your tax refund, in turn, might itself come as a check or direct deposit into a bank account you maintain, your wage or salary as paper, and your loan or other investment proceeds as a cashier’s check or a new account opened for you by a commercial or investment bank. These “polyglot” means of paying and being paid complicate your life in various ways. For one thing, you must carry multiple objects around with you, and keep in mind multiple passwords and PIN numbers. For another thing, the security—and privacy—afforded by some of these payment media will differ significantly from what’s offered by others. And, perhaps worst of all,insomeofthesecasesyourpaymentswon’t“clear”untilsomeappreciable v vi Prologue:MoneyWithout“Middlemen” timeafterthey“post”—“settlement”ofyourtransactionswilloftenbelagged, that’s to say, not occurring “in real time.” But these are just the most obvious worries or inconveniences thrown up by our “Babel” of multiple parallel payment systems. In many jurisdictions, the U.S. conspicuous among them, most payments other than those in cash require the maintenance of bank transaction accounts—the accounts with which chip cards and strip cards, not to mention most payment platforms like Zelle, Venmo and PayPal, are typically associated. Yet such accounts can be difficult to maintain, particularly for those who aren’t wealthy and can’t afford fees of the kinds banks and payment platform companies charge us. The result is that some 25% of the citizenry in the wealthiest country in the world, for example—the United States (“U.S.”)—are “unbanked” or “underbanked.” Small businesses fare little better—the “interchange” and related fees they must pay to facilitate electronic payments are prohibitive for many. That’s a bit odd in a “commercial republic” like that which the U.S. purports to be, let alone any “monetary exchange economy” like that of most if not all “developed” countries. In such republics and their economies, value-transfer and-storage platforms—that is, payment and savings modal- ities—surely amount to essential commercial and financial infrastructures, public goods that by definition ought to be freely available to all. Yet that is not all. Thanks to the intimate link between money and payment systems drawn out in this book, modern republics must modu- late transaction activity—that is, “money supplies” and “money velocity”—in order to manage “price stability” and “financial stability”—that is, “inflation” and “deflation,” “bubbles” and “busts.” Where the payments system makes use of intermediaries—banks, payment platform companies, and the like— the authorities charged with this form of maintenance must work through “middleman” institutions—commercial banks, “dealer” banks, and the like. This brings much leakage to credit and monetary policy, diminishing its efficacy in both inflationary booms and deflationary busts. In effect, public action is hostage to private interest. For public infrastructure is captive to private toll-takers. Now imagine a simpler, more elegant, more streamlined value-storage and -transfer architecture… Your iPhone or other “smart device” holds a digital wallet networked horizontally to all other citizens’ and businesses’ wallets andverticallytotherepublic’sfiscaland/ormonetaryauthorities—itsfinance ministry (“FM”) and/or its central bank (“CB”). To make payments to friends, employees, businesses, tax authorities, materials suppliers, or anyone elseintheirpersonalorprofessionalcapacities,yousimplycredittheirwallets Prologue:MoneyWithout“Middlemen” vii whiledebitingyours.Paymentstoyouoryourbusinesstakethesameform— creditings of your wallet and corresponding debitings of your payors’ wallets, all “in real time.” Yourwalletalsoservesasavalue-storagedevice—apersonaland/orprofes- sional digital “savings account.”The fiscal or monetary authority might also pay interest on our wallet accounts—as central banks do now on private sectorbanks’“reserveaccounts,”andasfinanceministriesdoonthesovereign debt instruments—treasury “bonds,” “bills,” and “notes”—that so many of their citizens (perhaps you yourself) purchase as safe savings vehicles. These rates then can be raised or lowered to encourage more or less saving accord- ingly as the republic’s monetary and fiscal agencies must encourage slower spending to lower inflation or accelerated spending to counteract deflation (a.k.a. “recession” or “depression”). Et voila, leak-proof monetary policy. But there is more. Because smart device ownership is far more universal than bank account ownership—in the U.S., for example, only 5%, not 25%, of the population is “unphoned”—the problem of the “unbanked” and“underbanked”isallbuteliminated.Paymentnetworkfeespaidbybusi- nesses,meanwhile,disappear.Inpresently“developing”countries,relatedly,a full banking and payments system can be had without trudging through the decades of slow steps the “developed” world had to traverse to establish full national “brick and mortar” banking and investment systems. Further, communities that find that various forms of presently unremu- nerated “care work” contribute to aggregate wealth and hence public revenue over time—a secondary schooler tutoring primary schoolers, for example, or a young person giving home care to an older person—can incentivize more such work by remunerating it over smart devices.The “proof of work” (“POW”) protocols that new digital payment technologies enable can for their part ensure real services—value adding services—are performed for these remunerations. These same technologies also afford means ofcryptographically protecting individuals’ and businesses’ digital identities and transactional privacy. The payment architecture can be programmed to replicate the privacy advantages now offered only by cash, while capturing the security advantages offered onlybyelectronicnetworking.Digitization,inotherwords,canbemade“all good,” with no offsetting “bad with the good” disadvantages or “tradeoffs.” In effect, what we’re imagining now is a digital infrastructure that isomor- phically mirrors the underlying credit and debit, the asset and liability, structures of all modern productive commercial societies. Legally and insti- tutionally speaking, all modern economies amount to massive social balance sheets,onwhichcomprehensive“double-entrybook-keeping”wouldinclude viii Prologue:MoneyWithout“Middlemen” everypublicandprivateunit’sdebtsandentitlements,allinterlinkedliability and asset structures. No actually tabulated balance sheet quite does this, of course (though we’ll find that central bank records quite nearly do it), but this is nevertheless the legal, monetary, and financial structure of all commercialsocieties—includingmostofthesocietiesofmodernAfrica,Asia, Europe, Oceania, and the Americas—established since the late medieval or early modern eras. Present-day payment and value-accounting practices obscure this shared underlying structure, and in so doing enable all manner of inefficiency and rent-extraction, as multiple for-profit entities purport to offer—for a price— bits and pieces of a dismembered commercial and financial infrastructure that should be—and can be—made freely available to all. The upshot is intolerable injustice and massively scandalous waste. It doesn’t have to be this way. While our present value-accounting, value- storage, and value-transfer systems are understandable outgrowths of an earlier time when the state of technology simply didn’t allow for comprehen- sive account-keeping across whole economies, that earlier time is now past. New modes of data-compiling, -storing, and -collating enable the construc- tionofliteralphysicalledgers(inelectronicdigitalform)thatreplicatethede facto ledgers that are all of our modern commercial and financial economies’ fund-stocks (“savings”) and fund-flows (“payments”). Something much like this compiling and tracking is done by our central banks worldwide already, for it’s the only way they can fulfill their public money-management mandates not “in the dark,” but transparently, with full knowledge,“inthefulllightofday.”Butwhatourpublicinstrumentalities— our central banks and finance ministries—benefit by we the citizens should benefit by too. Since they, our public agents, “keep” economy-wide macro ledgers, we, their principals, ought to be able to use them—to save and to spend, to invest and be invested in, through them. Happily, the new savings and payments technologies discussed in this book will enable just that. They will enable our savings and payments, and hence also our investment, modalities to catch up with our computing and communicationsmodalities.Thatwilleffectivelyconveytheproductivityand efficiencygainswroughtbythelattertoourpracticesandinfrastructuresthat make up the former.

They are accordingly acting quite swiftly to ensure that the public efficiencies offered by new technology remain restricted, for- profit, and thus expensive.

Praise for The Citizens’ Ledger “Computer scientists, financiers, and even some economists seem often to overlook the ways money, finance and accounting on the one hand, and money,banking,andcentralbanksontheotherhandallinteract.Oneresult isthattreatmentsofcentralbank-issueddigitalcurrencies(‘CBDCs’)tendto losesightofthefullrangeofcriticalconsequences–andopportunities!–that flow from alternative possible digital currency arrangements. After Hockett’s treatise, no such unsystematic or incomplete ‘siloed’ thinking will be possible. In highly accessible prose supplemented by simple intuitivediagrams,Hockettshowshowthetrillionsofcommercialandfinan- cial transactions that occur in our economies each day can be modeled as single national account books of millions of interlocking personal and insti- tutionalbalancesheets–full‘Citizens’Ledgers’thatdigitaltechnologyisnow able to replicate. The potential this opens is far more interesting – and far more exciting – than most current discussions of CBDC appear to appreciate. As Hockett demonstrates, the future now available to us includes transactional privacy andfreebankingservicesforallhouseholdsandbusinesses,leak-proofmone- tary policy for all central banks, and a transformed financial system that is once again geared toward production instead of mere speculation.” —U.S. Congressman Ro Khanna, Professor of Economics and author of Dignity in a Digital Age (2022) and Entrepreneurial Nation (2012) xi
