Chainlink co-founder Sergey Nazarov believes that growing the decentralization and scalability of oracle applied sciences are key to make sure belief within the DeFi ecosystem.

Oracles play a key position within the appropriate functioning of DeFI protocols by connecting them to real-world knowledge.

Nonetheless, the trustworthiness of oracles turns into compromised in cases the place they depend on a single knowledge supply to retrieve data. For example, in line with Nazarov, excessively centralized oracles enabled 5 latest flash mortgage assaults, which resulted in DeFi protocols dropping round $40 million.

Flash loans, a type of mortgage that doesn’t require any collateral, can be utilized to govern the worth of an asset and steal funds from a DeFi protocol.

“You do not wish to simply take one change [as a price discovery source] and hope for the most effective, as a result of if that one change turns into thinly traded or if anyone will get a flash mortgage, (…) then you definately’re ready the place anyone controls the outcomes in your DeFi protocol”.

In response to Nazarov, the one technique to forestall such assaults is ensuring that the protocol’s worth discovery mechanism depends on a number of knowledge sources. That’s the reason Chainlink focuses on constructing decentralized oracle networks.

“We’re sourcing knowledge from many various knowledge suppliers connecting us to a whole bunch of exchanges and due to this fact, wherever quantity shifts, Chainlink can correctly characterize the correct international worth”, he identified.

In response to Nazarov, a correctly functioning oracle community ought to be capable of scale accordingly with the scale of the worth locked within the DeFi protocol.
