The Portable People: The Jewish Case for Bitcoin

The glass came down around midnight. By dawn, more than 7,000 Jewish-owned businesses had been smashed, 267 synagogues were burning, and 30,000 Jewish men were on their way to Dachau, Buchenwald, and Sachsenhausen. The Nazis called it Kristallnacht -- the Night of Broken Glass -- as if the violence had been done to windows rather than to people.

What is less remembered is what came next. Twelve days later, on November 21, Hermann Göring imposed the Judenvermögensabgabe, an "atonement tax" of one billion Reichsmarks levied on German Jews -- for the crime of having been attacked. Bank accounts were frozen. Safe deposit boxes were opened by decree. Gold, silver, platinum, and jewelry above a token allowance had to be surrendered at the local pawnshop, at prices the state set. Real estate became unsellable except to Aryan buyers at confiscatory discounts. In the months that followed, the Reich Flight Tax was raised again, until escaping Germany with any meaningful portion of one's wealth became a mathematical impossibility.

The lesson German Jews learned, in the cold light of November 1938, is the oldest lesson in Jewish history: a bank account is a permission slip. A deed is a permission slip. A wedding ring on your finger is a permission slip. Anything you own that the state can find, the state can take. And anything you own that you cannot carry across a border in your own head, you do not really own at all.

This is the lesson the Jewish people have been forced to learn, and re-learn, for two thousand years. It is also the lesson that, in 2008, an anonymous cryptographer made it possible -- for the first time in history -- to refuse.

II. The Portable People

Jewish history is, among other things, a history of expulsion. England in 1290. France in 1306, and again in 1394. Spain in 1492. Portugal in 1497. Provence, Naples, Bavaria, Vienna, Lithuania, Bohemia, the Papal States. Russia's May Laws and pogroms drove two million eastward Jews west between 1881 and 1914. Germany and Austria, of course, between 1933 and 1945. Iraq, Egypt, Yemen, Libya, Syria, and Morocco emptied of nearly a million Jews in the two decades after 1948. Iran after 1979.

Every expulsion follows the same template. First, restrictions on what Jews may own, where they may live, what trades they may practice. Then, a special tax. Then, a confiscation. Then, a deadline to leave -- with the contents of one's pockets and nothing more. Spain in 1492 gave four months. The Reich in 1938 charged for the privilege of leaving at all.

It is no accident that Jews became, disproportionately, dealers in diamonds, in gold, in portable arts, in skills that travel inside the skull. A diamond is the closest thing the physical world offers to censorship-resistant wealth: small, fungible enough, internationally recognized, and difficult -- though far from impossible -- for a customs officer to find. The wedding band, the gold tooth, the rolled banknote in the lining of a coat: these are not stereotypes. They are technologies. They are what a people develops when it cannot trust that the bank, the deed, or the king's word will be there in the morning.

But every one of these technologies fails under sufficient pressure. Customs agents at the German border in 1939 were instructed to slit the linings of coats. Jewelry was confiscated at the dock in Baghdad in 1951. Diamonds can be found in a body cavity by a doctor in uniform. Gold is heavy. A briefcase full of cash buys a single bribe and then it is gone. The history of Jewish portable wealth is a history of ingenuity defeated, again and again, by the simple fact that physical objects can be physically taken.

Until they couldn't.

III. What Satoshi Solved

In October 2008, a person or persons calling themselves Satoshi Nakamoto published a nine-page paper proposing a peer-to-peer electronic cash system. Most of the early debate about Bitcoin focused on its monetary properties -- the fixed supply of 21 million coins, the disinflationary issuance, the rejection of central bank discretion. These are interesting questions and reasonable people disagree about them.

But the monetary debate has always obscured the deeper invention, which is not economic but political. For the first time in human history, Bitcoin made it possible to own something of value that has no physical existence, cannot be located by a search of one's home or person, cannot be frozen by a bank, cannot be confiscated by a state, and can be transported across any border on Earth in the form of twelve words memorized in one's head.

Consider what this means against the template of Jewish expulsion.

Seizure. A government can freeze a Jewish-owned bank account with a phone call, as the Reich did in November 1938 and as Iran did in 1979. A government cannot freeze a Bitcoin wallet whose private key exists only inside one human being's memory. There is nothing to freeze. There is no counterparty to compel.

Confiscation. The Nazis ordered the surrender of gold and jewelry above a tiny allowance, knowing that physical objects must be stored somewhere and that storage is searchable. Bitcoin has no physical existence and no storage location. The wealth is the key, and the key can be twelve English words.

The flight tax. The Reich's exit tax worked because leaving Germany meant moving wealth through the banking system or carrying it physically across a guarded border. Bitcoin crosses borders at the speed of light and at the cost of a few dollars in transaction fees. A refugee who arrived in Lisbon in 1940 with nothing but the clothes on her back could, today, arrive with her family's entire net worth -- provided she remembered the words.

Discriminatory denial of service. For most of European history, Jews were forbidden to own land, join guilds, or hold certain professions. In the modern era, this becomes debanking -- the quiet refusal of financial services on the basis of identity, religion, or politics. Bitcoin's permissionless architecture renders this category of exclusion technically impossible. The network does not know who you are and cannot be made to care.

This is not a small thing. It is the first answer in two thousand years to the oldest material problem of Jewish life.

IV. The Argument From "Never Again"

The phrase "Never Again" has, in much contemporary discourse, narrowed to mean "never again to us." This is an understandable contraction, but it is not the original meaning. The original meaning is structural. Never again may a people's wealth be made hostage to a state that has decided to destroy them. Never again may the rule of law collapse so completely that a tax notice and a confiscation order become the prelude to a train station and a camp.

Building durable institutions against tyranny is the work of constitutional design, of courts, of armies, of international norms. These are necessary and they are insufficient. They are insufficient because every generation produces fresh evidence that institutions can rot, that courts can be packed, that armies can be turned inward, and that international norms are observed mainly by those who do not need them. Theodor Herzl wrote Der Judenstaat not because he believed Vienna had become uninhabitable in 1896 but because he had watched the Dreyfus trial in Paris -- in the most civilized capital of the most liberal century -- and concluded that civilization was not, on its own, a guarantee.

What Bitcoin offers is not a substitute for the Jewish state, for the institutions of the diaspora, or for the moral and political work of building societies that do not turn on their minorities. It offers something more modest and more radical: an exit option that cannot be closed by the people one is trying to exit from. The historian Salo Baron called the lachrymose conception of Jewish history -- the idea that Jewish life is essentially a chronicle of suffering -- a distortion. He was right. But the long Jewish memory of what states have done to Jewish wealth is not lachrymose. It is empirical. And the empirical answer to that memory, until 2008, was: there is no answer. Only fewer of your eggs in any one basket, and a packed suitcase by the door.

There is now an answer. The answer is twelve words.

V. The Objections

A serious case requires a serious accounting of the objections.

The first is that Bitcoin is volatile, speculative, and has been associated with fraud, with criminality, and with a great deal of foolish wealth and foolish loss. All of this is true. It is also true of the diamond trade, of physical cash, of any instrument that exists outside the surveilled perimeter of the regulated financial system. The properties that make an asset useful to a Jewish refugee in 1939 are the same properties that make it useful to a money launderer in 2026. This is a feature of the underlying technology, not a bug, and it is the price of the protection. Cash has been used by every criminal in history. We do not, for that reason, propose to abolish it.

The second is that Bitcoin's value depends on social consensus, on network effects, on continued belief -- and that belief can collapse. This is true. It is also true of gold, of fiat currency, of land titles, and of the legal recognition of Jewish citizenship itself. Every store of value is, in the end, a social convention. The question is which conventions are robust against which failures. Bitcoin is uniquely robust against the specific failure mode that has destroyed Jewish wealth more often than any other: the decision of a sovereign to take it.

The third is that Jewish law -- halacha -- has complex things to say about money, about lending, about the prohibition on idolatry, and about the obligations of communal property. These are real questions and they deserve real rabbinic engagement. They are not, however, questions that distinguish Bitcoin from any other modern financial instrument. The Talmud accommodated bills of exchange in the Middle Ages and joint-stock corporations in the modern era. It is capable of accommodating cryptographic bearer instruments. The work has begun; it will continue.

The fourth, and most serious, is that an over-reliance on Bitcoin as an exit option could weaken the political will to build societies worth not exiting from. This is the deepest objection and it deserves the most direct answer. The Jewish answer to two thousand years of expulsion has never been only flight. It has been law, learning, institution-building, citizenship, and -- since 1948 -- sovereignty. Bitcoin does not replace any of these. It supplements them. It is the lock on the back door of a house whose front door one is still committed to defending. A people that has learned, the hard way, that even the best-defended houses sometimes burn, is entitled to a back door.

VI. The Quiet Revolution

Somewhere in the world tonight, a Jewish family in a place that is becoming uncomfortable -- and there are several such places, more than there were a decade ago -- is writing twelve words on a piece of paper, photographing them, memorizing them, and then burning the paper. The act takes about an hour. The wealth those twelve words represent can be a few hundred dollars or a few million. It does not matter. What matters is that, for the first time since the destruction of the Second Temple, the question "what do we take if we have to leave tonight?" has an answer that does not depend on the kindness of customs officials, the discretion of bankers, or the speed of one's feet.

This is not the only thing Bitcoin is. It is a speculative asset, a payments network, a political symbol, a community, a casino, and a great deal else. People will continue to argue about its monetary economics, its environmental footprint, and its appropriate regulation. These arguments will be carried on by people with stronger views and better credentials than mine.

But there is one argument that has not been carried on enough, and it is the one I have tried to make here. It is that a technology which renders confiscation technically impossible is not a curiosity. It is the most significant material development in the long history of a people who have been confiscated from more often than any other. The Jewish case for Bitcoin is not that it will make anyone rich. It is that, for the first time in two thousand years, the lock on the back door is one that no king, no commissar, and no Gauleiter can pick.

The glass came down in Berlin on a Wednesday night in November. The wealth went into the vaults of the Reich the following Monday. If the families on the trains that winter had been able to carry their savings out in the form of twelve words memorized between mother and daughter, the history of the twentieth century would not have been changed -- the camps were not, in the end, about money -- but a great many private histories within it would have been. Some grandchildren who were never born would have been born. Some lives that ended in Łódź or Salonika or Vilna would have ended, instead, in Lisbon or São Paulo or Tel Aviv.

We cannot give those lives back. We can, this time, give the next generation the tool that the last one did not have. That is the Jewish case for Bitcoin, and I do not think it is a small one.
