Truthbound Data Asserter

Connecting Physical Infrastructure with Decentralized Assurance

Truthbound brings data assertion to the Aptos blockchain, using the Optimistic Oracle V3 from UMA Protocol as its foundation, where data providers can submit off-chain data for validation and make it accessible on-chain for other decentralised applications.

Sample Data Assertions:

ID Data ID Data Description Status
1 WEATHER_LDN_20241015 { "temperature": 15, "precipitation": 0.2, "humidity": 60 } Represents the weather conditions in London on October 15, 2024. Independent parties can verify this by cross-checking with trusted weather data sources. Resolved
2 BTC_PRICE_20241016_12PM 27500 Asserts the price of Bitcoin at a specific time (October 16, 2024, at 12 PM). Data providers can bring in exchange data to verify the correctness. Resolved
3 VALIDATOR_0x1234_STATUS_20241016 { "status": "active", "balance": 3200, "performance_score": 95 } Details the status of a specific Beacon Chain validator on a particular date. It’s useful for tracking the validator’s status in real-time or at specific intervals. Resolved
4 LSD_ETH_20241016 { "staked_amount": 100, "liquidity_ratio": 1.05, "total_yield": 5 } Represents data related to a liquid staking derivative position, such as the amount staked in ETH, the liquidity ratio, and the yield accrued. Resolved
5 OFF_CHAIN_COMPUTE_20241016 { "input": [1,2,3,4,5], "algorithm": "FFT", "output": [15, -4, 3, 7, -2] } Provides an assertion for the result of an off-chain Fast Fourier Transform (FFT) computation. This shows how complex off-chain computations can have their results asserted on-chain for verification. Resolved
6 REPI_LA_20241015 678.23 Asserts the Real Estate Price Index (REPI) for Los Angeles on October 15, 2024. Useful for tokenized real estate or property derivatives. Resolved
