DeepThought: a Reputation and Voting-based Blockchain Oracle. (arXiv:2209.11032v2 [cs.CR] UPDATED)

Thanks to built-in immutability and persistence, the blockchain is often seen
as a promising technology to certify information. However, when the information
does not originate from the blockchain itself, its correctness cannot be taken
for granted. To address this limitation, blockchain oracles -- services that
validate external information before storing it in a blockchain -- were
introduced. In particular, when the validation cannot be automated, oracles
rely on humans that collaboratively cross-check external information. In this
paper, we present DeepThought, …
