"The Library of Alexandria was the single greatest repository of human knowledge in the ancient world. When it burned, humanity lost irreplaceable records of our collective history."
History doesn't have to be lost anymore.
About the Library of UMA
We're building humanity's first incorruptible record of history—a decentralized archive that can never be burned, censored, or rewritten.
Why This Matters
Throughout history, those in power have rewritten the past to control the present. The truth has always been vulnerable.
Soviet Photo Editing
Stalin systematically erased political opponents from historical photographs after their execution or exile.
Orwell's Warning
George Orwell's dystopia predicted how authoritarian regimes would control the past to control the future.
Tiananmen Censorship
The Chinese government continues to censor and deny the events of the Tiananmen Square protests.
Digital Manipulation
AI-generated deepfakes and coordinated disinformation campaigns threaten historical accuracy at unprecedented scale.
The Solution
UMA's decentralized oracle creates an immutable record that no government or corporation can alter.
How It Works
UMA's Optimistic Oracle creates a decentralized verification system that ensures truth without central authority.
Event Submission
Real-world events are submitted to the UMA oracle with supporting evidence. Anyone can propose an event for verification.
Decentralized Verification
Token holders worldwide review and vote on the accuracy of submissions. Economic incentives ensure honest participation.
Permanent Recording
Verified events are permanently recorded on the blockchain. Once written, the record cannot be altered by anyone.
The Data Verification Mechanism (DVM)
UMA's DVM is a dispute resolution system that uses economic game theory to ensure accurate reporting. Voters stake tokens and are rewarded for voting with the majority. Bad actors who vote incorrectly lose their stake.

Built on blockchain technology, the Library of UMA leverages cryptographic guarantees to ensure permanence and immutability.
Immutable Records
Once an event is verified and recorded on the blockchain, it becomes cryptographically impossible to alter. No government, corporation, or individual can modify or delete the historical record.
Global Decentralization
The record is maintained by thousands of nodes worldwide. There is no central point of failure or control. The truth is protected by the collective security of the network.
Complete Transparency
Every verification, every vote, every transaction is publicly visible. Anyone can audit the process and verify the integrity of the historical record.
Eternal Permanence
Unlike physical libraries that can be destroyed, blockchain records persist as long as the network exists. The Library of UMA is designed to outlast civilizations.
