Data philosophy
obsila is designed to transform public market, liquidity and network data into transparent research metrics. Where practical, calculations are performed from raw or minimally transformed source data rather than licensed proprietary indicators.
Current sources
| Source | Use | Typical refresh |
|---|---|---|
| CoinGecko / fallback market source | Spot market prices, market capitalization and broad market statistics. | Several hours |
| Blockchain.com public charts | Bitcoin historical market price and selected network statistics. | Daily / periodic |
| DefiLlama stablecoin data | Aggregate stablecoin supply and liquidity-growth calculations. | Periodic |
| Kraken public market data | ETH/BTC relative-strength history where used. | Daily / periodic |
| obsila calculations | Regression models, drawdowns, moving averages, volatility, risk and regime diagnostics. | Calculated from cached source data |
Caching
obsila intentionally favors reliability and low operating cost over high-frequency updates. Data is cached at the Cloudflare layer and may be reused across visitors. Slow-moving research charts do not require second-by-second updates.
Attribution and rights
Third-party data remains subject to the applicable provider terms and underlying rights. Inclusion on obsila does not imply ownership of third-party datasets. Before any commercial expansion, data-source licensing should be reviewed again against the intended use.
Corrections
If a source changes its methodology, endpoint, historical series or access policy, obsila may revise calculations or switch sources. Material methodology changes should be reflected in the Methodology page and model versioning.
