Uncovering the Hidden History of Bitcoin Oracles

When people talk about crypto oracles, Ethereum usually steals the spotlight. But Bitcoin actually used oracles way back in the day to handle real value for feeds, arbiters and key release services. I came across a study that looks through blockchain history to see what those early Bitcoin oracles were really up to. Tracking down this ancient data shows that understanding early network activity isn't as simple as you'd think.

The researchers set out to trace Bitcoin oracle use from its beginning through July 2026. To do this, they analyzed the full chain up to block 958,628, searched an 854-million-row public-key index and checked 1,149 Counterparty bets alongside archived DLC records and live Nostr relays. They found that while early contracts remain on the blockchain, many original event descriptions have disappeared. The study also revealed that public registries can be misleading, since 95% of pre-2018 Counterparty sources that declared an oracle fee were never bet on. Additionally, only 0.1% of archived Bitrated keys appear on-chain overall, compared with 10 of 19 keys captured in 2014. While sports dominated Counterparty volume, a daily price series dominated DLC announcements, showing how protocol rules shape what survives in the historical record.

If you want the full details, the paper is called On-Chain Archaeology of Bitcoin Oracles: Evidence of Use under Limited Observability and it was written by Giulio Caldarelli. You can find it at arxiv.org/abs/2610.11439.
