DIA (Transparent, fully customizable feeds sourced trade-by-trade) versus Chronicle (Gas-efficient, fully verifiable oracle born inside MakerDAO ) — how they differ on type, coverage and what they’re built for.
| DIA | Chronicle | |
|---|---|---|
| Type | Push + Pull | Push |
| Update model | Open-source, transparent methodology: feeds are computed from raw trade-level data and can be customized per integrator. Lumina adds a gas-efficient layer. | Scribe: Schnorr signature aggregation decouples validator count from verification cost, so updates stay cheap as the validator set grows. |
| Chains | 50+ | Ethereum + L2s |
| Feeds | Custom + long-tail | 160+ |
| Security | Fully transparent, open-source data pipeline; custom feeds are auditable end-to-end. | Transparent validator set with cryptographic (Schnorr) aggregation; every update is independently verifiable. |
| TVS* | Specialized | ~$7.5B |
| Token | DIA | — |
| Best at | Transparency and long-tail coverage — list niche or RWA assets the big providers don’t carry | Lowest gas cost in the market (≈63% cheaper than Chainlink on Ethereum), with a strong RWA / institutional focus |
* Approximate total value secured — dated market snapshot (DefiLlama / provider reports, 2026).
Pick DIA when transparency and long-tail coverage matters most; pick Chronicle when lowest gas cost in the market (≈63% cheaper than chainlink on ethereum), with a strong rwa / institutional focus matters more.
