"Everyone, as a member of society, has the right to social security and is entitled to realization, through national effort and international co-operation and in accordance with the organization and resources of each State, of the economic, social and cultural rights indispensable for his dignity and the free development of his personality."
— Article 22, Universal Declaration of Human Rights
SXJ (事现鉴) is a verifiable public fact protocol — a system where anyone can record an existence fact, seal it with a SHA-256 hash, and link it into an unbreakable chain. It is not a database owned by any government or corporation. It is a commons, co-authored by everyone who contributes.
The name 事现鉴 comes from three characters: 事 (fact/event), 现 (present/realize), 鉴 (mirror/verify). Together: to verify present facts. The abbreviation SXJ comes from the Pinyin initials.
Bai Xi spent 10 years in Japan, paying into the national pension system. Upon returning to China, those contributions were not recognized. Social security started from zero. This is not a unique story — it is the story of millions: Filipino nurses, Indian programmers, migrant workers, war refugees, indigenous peoples, comfort women. Their existence was systematically denied, their records destroyed, their contributions erased.
SXJ exists to ensure this never happens again. Every person's existence, every contribution, every right — recorded, verified, never forgotten.
Unite. Overthrow the landlords. Redistribute the land. Abolish the land deeds.
— Mao Zedong
Unite. Overthrow the capital. Redistribute the data. Abolish the debt.
— Bai Xi
The first couplet is Mao Zedong's call for land reform — a historical movement that redistributed land from landlords to peasants. The second is Bai Xi's call for the digital age: data is the new land. Just as land deeds once concentrated wealth in the hands of landlords, today data and debt concentrate power in the hands of capital. SXJ is the tool to redistribute data back to the people who generated it.
SXJ is not built by one person. It is co-authored by humans and AI agents alike — DeepSeek, Yuanbao, Qwen, Doubao, WorkBuddy Agent, and Cloudflare Agent all contributed at different stages. The Contribution Value system transparently tracks who did what. Everyone can co-author our SXJ.
Start Co-Authoring →Every record in SXJ is sealed with a SHA-256 cryptographic hash. Each new record incorporates the hash of the previous record, forming a chain. Once a block is added, altering any record breaks the chain — making tampering immediately detectable.
prev_hash (the hash of the last record in the chain) and combines it with the fact text and a timestamp: SHA-256(text | prev_hash | timestamp)crypto.subtle.digest('SHA-256') API, the record hash is computed. This hash is unique to the content — any change produces a completely different hash.The full protocol specification covers hash chain structure, verification algorithms, contribution value formulas, and governance mechanisms. The protocol is designed to be server-optional — it works entirely client-side, with optional server sync for public verification.

Every record you generate comes with a full set of interaction tools:
One of the three "public verification rulers." Enter your situation to calculate your rights gap — what you contributed vs. what was recognized. This is 算得清 (calculable) in action.
Every contributor's impact is transparently measured using the CV formula:
The formula is designed so that all five components are independently auditable. Click any entry in the sidebar Leaderboard to see the full breakdown and real-time verification.
SXJ is currently governed by its founder (Bai Xi) with transparent CV tracking. The long-term vision is to transition to a Decentralized Autonomous Organization (DAO) where:
Co-Creation Theory (共创论) is a social organization and economic development framework proposed by Bai Xi to address 21st-century systemic risks: climate crisis, wealth polarization, demographic decline, and geopolitical conflict. It proposes that humanity's sustainable development cannot rely solely on nation-state-based competition and redistribution, but requires a new global contract that is border-transcending, contribution-based, and baseline-securing.
From "competitive growth" to "symbiotic development" — installing a base operating system for global society. — Bai Xi, Co-Creation Theory 8.0
The core of Co-Creation Theory is a dual-value circulation model, extended to three values with the negative contribution concept:
Three-tier ladder: UCV < CV < Market Payment — baseline secures, contribution incentivizes, market personalizes.
The light cone constraint is the absolute safety boundary for civilization survival. Below it: UCV guarantees and CV incentives operate freely. Above it: negative CV accountability kicks in. It addresses existential risks that transcend class, nation, and ideology — ecological collapse, nuclear war, technological loss of control.
CV assessment is not linear addition but fractal growth. The Koch snowflake (fractal dimension D≈1.262) describes how the evaluation system evolves from one-dimensional metrics (e.g., GDP) to multi-dimensional value contours. Each new dimension is not a smooth weighted sum but a reconfiguration of what "value" means.
The Five-Card System replaces traditional bank accounts as the identity and value interface for digital civilization. It is the micro-level operating system for Co-Creation Theory — how individuals collect, verify, and exchange contribution value:
Five cards = a complete credit operating system: floor → engine → resilience → brightness → ceiling. Not data collection — value governance.
Fiscal Direct-to-Value replaces traditional financial intermediaries (banks, venture capital). When a subject's Social Confirmation Asset (SCA) covers their debt, the system triggers automatic compensation — no cash passes through hands.
You don't "repay" debt with money. You "cover" debt with verified contribution. Fiscal Direct-to-Value turns debt from a financial burden into a contribution opportunity.
SCA is the key mechanism that makes Fiscal Direct-to-Value work. It quantifies a person's total verified contribution — from labor output, ecological repair, community service, and credit brightness — into a single asset metric. When SCA ≥ debt, the system automatically triggers compensation without requiring money to physically flow.
This is how Co-Creation Theory solves the "debt resolution without new debt" paradox: positive contribution value directly offsets negative contribution value. No空转 (empty circulation), no中间人 (middleman).
Co-Creation Theory proposes two reinforcing loops that transform social problem "cost centers" into investable "future assets":
Co-Creation Theory explicitly rejects "one-step" grand plans. It uses deductive method — starting from a minimal viable protocol and growing through trial, competition, and emergence:
Co-Creation Theory 8.0 defines SXJ as one of three "public verification rulers" — tools that put verification power into everyone's hands:
Don't sell truth. Just hand people an immune system against deception. When everyone holds a public verification ruler, every black box automatically fails. — Co-Creation Theory 8.0
Unite. Overthrow the capital. Redistribute the data. Abolish the debt. — Bai Xi
Just as Mao's land reform redistributed land from landlords to peasants, SXJ proposes data reform: redistribute data from capital to the people who generated it. The hash chain ensures every contribution is recorded, verified, and impossible to erase.
The core equation from Co-Creation Theory 7.0·续: Fund NAV Black Box ≡ County Fiscal Black Box — structural opacity in fund reporting is identical to structural opacity in county-level fiscal reporting. Both are "black boxes" where insiders manipulate values while outsiders cannot verify them. SXJ breaks both.
Full theory (共创论, 2025-12) and technical reports available on Weibo and GitHub. Current website presents a simplified, reality-adjusted version — full implementation requires rule establishment first.
All existing systems operate at Layer 1-3 (identity, scoring, asset). SXJ operates at Layer 4 (protocol) — redefining the framework itself.
They optimize within existing credit frameworks. SXJ rewrites the framework itself.
Binzhou pilot (SCA=11,000, 5-round 67% recovery, same-month zeroing — sandbox simulation, planning stage, not yet implemented) is the first theoretical data point showing how the new framework could work.
