If Ethereum’s vision were ever fully realized, what would a free and decentralized society actually look like? That is the question running through Vitalik Buterin’s first novel, Snowmoon.
On Sept. 27, Buterin published the science fiction work on his personal website. The book spans 32 chapters and 103,000 English words, with a Chinese translation running beyond 170,000 characters. According to the release note described in the article, every plot point was written by hand, while AI was used only for spell-checking and formatting. The book is open-sourced under GPL v3.
At first glance, the project can look like a programmer’s ambitious side hobby. But the novel does more than tell a story. It places Buterin’s decade-long thinking on decentralized governance, privacy, mechanism design and pluralism inside a fictional world, then tests those ideas under pressure through domestic life, wartime danger and political argument.
A daily world secured by cryptography
The setting is a future that never had Bitcoin or Ethereum. Even so, the social logic of the world reads as a broad expansion of Ethereum’s political and technical imagination.
The main character, Gladias, is a citizen of Veridia, a highly developed decentralized governance society. In the opening scene, he is walking through the capital city of Meldan when a drone passes overhead. Before he can react, the zero-knowledge authentication protocol on his watch has already verified that the device is only a toy and that its navigation algorithm includes safety restrictions preventing it from coming within half a meter of a human without permission. His watch learns that the drone is not a threat, and nothing more is revealed.
The scene captures the book’s method in miniature. An abstract concept Buterin has discussed repeatedly in essays and technical writing — the everyday use of zero-knowledge proofs — becomes a warm street-level moment involving a parent, a city and children chasing a drone. The technical explanation is folded into the narrative itself.
Veridia’s institutions: tax, subsidy and decentralized oversight
Veridia is where the novel’s world-building is most detailed. Very little is banned outright. Instead, the society relies on a fine-grained system of taxes and subsidies to steer behavior.
Buildings pay an “aesthetics tax,” with ratings assigned by citizens selected through cryptographic sortition and then expressed through quadratic voting. A building widely seen as ugly is not demolished, but it is taxed more heavily.
Music performances are also taxed based on “social impact,” with five categories ranging from works that “strongly promote personal development and civic responsibility” at a 0% tax rate to performances that “strongly promote violence and hatred” at 40%.
These systems are administered by a decentralized organization called the Order of Steering. “Keepers” set tax standards. “Sentinels” audit individual businesses. Gladias is training as an “Acolyte,” and if his prediction score falls below 90, he has to wait another year for promotion.
The same world-building appears in domestic arrangements. Gladias has two biological children and co-raises two more children with another couple under Veridia’s rotating “co-parenting family” system, switching every six months. During one dinner scene, the family orders from an automated delivery truck called the Dzego food truck using handheld devices and pays in zipcoins. Transaction privacy is the default. Only Gladias and the restaurant know that a 10.5-zipcoin order took place.
A second narrative line under military occupation
The novel opens a second thread in Chapter 2.
Zei, a teenage character, lives in a country that has been under military occupation by the Arctic Empire for 100 years. On the surface, Dzego is controlled by a corrupt puppet government. Underground, it operates a secret education and governance network coordinated through cryptography.
Zei attends classes at a “decentralized university,” or DU. Classroom locations remain hidden until a few minutes before the session, when they are decrypted through encrypted broadcasts. The teaching spaces are lined with anti-signal foil, and students routinely scan the room with handheld devices to detect unknown electronics.
Dzego’s survival strategy is condensed into a line in a fictional language: “Gie fe kiu kai ci bin hu,” translated as “Root yourself, do not stick out.” In practice, that means replacing centralized heavy industry with distributed manufacturing and replacing vulnerable leaders with anonymous cryptographic coordination.
The climax of the chapter is a bombing. A bomb dropped by the Arctic Empire collapses the floor beneath Zei’s classroom. Had the room assignment not changed at the last minute, everyone would have died. Zei’s arm is broken by falling debris. At that point, cryptography is no longer a classroom abstraction. It is infrastructure that keeps people alive.
When the two worlds meet
The two storylines gradually converge. Gladias travels from Veridia to Dzego and becomes an adviser to the local resistance group known as Kungaupei. The second half of the novel shifts toward a larger geopolitical conflict: Veridia and Dzego join forces against the Arctic Empire and attempt to liberate the occupied province of Northglade.
That convergence puts two civilizational models into direct contact. Veridia represents a society built around decentralized governance, privacy and carefully designed institutional incentives. Dzego shows what cryptography and decentralization mean under coercion, surveillance and occupation. The same technical tools carry different weight depending on the structure of power around them.
The ending debate: should society have a goal?
The final chapter returns to Meldan. The war has paused. Northglade has been liberated, though the Arctic Empire still retains its core territory. People in the streets are removing surveillance cameras installed during wartime. In shops, emergency rations are being replaced by red flowers used to celebrate liberation.
Gladias, Seila and Zei meet the Veridian politician Verdow in the parliament building. Their conversation forms the book’s central philosophical argument.
Zei says Veridia is missing a critical capability: forecasting the future. Existing systems of voting and audit measure present opinion, but they do not create a formal place where people state, “If we do X, Y will happen,” and then rise or fall based on whether those forecasts prove right. He proposes introducing AI, but only as “a participant, not the game itself,” allowing different people to choose different AI systems to assist decisions while humans remain accountable for outcomes.
Verdow pushes back with a deeper question: should a society have an overarching goal at all? In his view, the Arctic Empire is better than anyone else at executing goals. Build a perfect goal-executing machine, and what you get is the Arctic Empire.
Seila answers with the metaphor that gives the article its frame. She compares society to a lake. Every water molecule moves independently. There is no master plan, only countless particles following their own paths. Yet the surface still finds balance, because whenever one part drops below another, gravity pulls water in to level it out. In summer, a good society should move like water. In winter, it should freeze into ice to resist invasion.
Her line captures the novel’s political core: resist the Arctic Empire, but do not become it.
The final image is Gladias standing on the roof of the parliament building holding tea and rice, looking out over Meldan. Tree-covered districts stretch below him. Medieval-style towers rise above the canopy. A corporate headquarters shaped like an airplane still looks awkward in the skyline, though street-level trees hide it when people walk below. The final note is simple: “Meldan is home.”
When Buterin stops writing papers
The reading experience, as described in the article, carries a distinct tension. On one side, Snowmoon is plainly a novel written by a programmer. Emotional depth is limited in places. Gladias often feels less like a fully conflicted literary protagonist than a guide leading the reader through Veridia’s institutions. Some dialogues resemble governance-forum proposals. At moments, the information density is high enough to feel close to a research draft.
But the novel also does something Buterin’s blog posts have not. It makes governance mechanisms feel alive.
When Gladias stands at a concert, listens to violent lyrics, worries about how to score the band’s social impact and at the same time thinks about his own apprentice rating, the combination of quadratic voting, tiered taxation and reputation systems stops being a formula. It becomes a human decision made under bias, time pressure and imperfect information.
When Zei explains the second law of thermodynamics through information theory in class, only for the room to be destroyed by bombing, the importance of cryptography and decentralization shifts again. In Veridia, they improve governance. In Dzego, they are conditions for survival.
That contrast points to why fiction may have appealed to Buterin. A paper can show that quadratic voting has desirable preference-aggregation properties under Nash equilibrium. A novel can show a person giving a neutral rating to a violent metal band out of “raw intuition,” then feeling proud of that act. One is mathematical optimization. The other is human reality. A workable governance system, in this reading, has to hold both.
Water, ice and the politics behind the novel
The article argues that the book’s deepest layer lies in that last debate over whether society should have goals. Verdow says the Arctic Empire is a perfect goal-execution machine. Seila argues that an ideal society should resemble water rather than ice. Zei insists that AI should participate but never serve as the judge.
Read this way, those exchanges sound less like ordinary science fiction dialogue and more like Buterin’s response to current arguments over AI governance. When Sam Altman talks about AGI helping humanity achieve shared goals, Snowmoon asks an earlier question: do people really know what they want? And if desire is written into code and pushed to its limit, does the result become the Arctic Empire?
Buterin also released the novel under GPL v3. In the copyright note cited by the article, he wrote that readers may adapt the work into a film or animation, but must open-source the production process as well. That choice extends the book’s own theme: knowledge and creation should circulate as freely as water in Veridia’s imagined lake.
At the end of the AI-use statement, he added a line the article calls unusual for a programmer: “Snowmoon was written with love.”
A book-length answer to an Ethereum question
The novel runs 100,000-plus words, 32 chapters and four months of solitary writing, all in service of a story about defending freedom through cryptography. The article’s judgment is measured. The prose may not be polished, and the characters may have room to grow. Even so, it suggests Snowmoon may be one of the few works to use an entire book to seriously answer a single question: if Ethereum’s vision ever came true, what would everyday life look like?
The answer is warmer than the reader might expect. Not a cyberpunk wasteland of cold numbers, but a place with trees, dinner tables and children running after drones. A place where ugly buildings are not torn down, only taxed more. A place where someone can wear a purple privacy robe to a violent metal concert and then go home to eat Dzego takeout.
In the end, the novel leaves not a slogan, but a word: home.
